| | 2. | COMPANY OVERVIEW
| | -- | ----------------

Sierra Metals is a diversified Canadian mining company focused
on the production, exploration and development of precious and base metals in Peru and Mexico. The Company plans to continue growing
its production base through brownfield exploration investments within its properties. The Company’s key priorities are to
provide high returns on invested capital, to generate strong cash flows and to maximize shareholder value. The Company has three
producing mining properties and manages its business on the basis of the geographical location of its mining projects. The Peruvian
Operation (“Peru”) is comprised of the Yauricocha mine (“Yauricocha” or the “Yauricocha Mine”),
located in the province of Yauyos, its near-mine concessions, and exploration and early stage properties. The Mexican Operation
(“Mexico”) includes the Bolivar (“Bolivar” or the “Bolivar Mine”) and Cusi (“Cusi”
or the “Cusi Mine”) mines, both located in Chihuahua State, Mexico, their near-mine concessions, and exploration and
early stage properties. The Company’s strategic focus is currently on its operations, improving efficiencies, as well as
pursuing growth opportunities at, and surrounding, its operating projects. The Company is also considering other opportunities
to add value and expand through external growth. Exploration remains a key aspect of the improvement programs being implemented
at all three of the Company’s mines and there is optimism that these brownfield exploration programs will continue to add
increased economic tonnage going forward. Examples of this can be seen at Yauricocha with the Esperanza, Cuye-Mascota zones, at
Bolivar, with the Bolivar West and Northwest zones, as well as at Cusi, with the Santa Rosa de Lima Zone. These results provide
potential to further grow mineral resources and enhance shareholder value.

through the production of higher volumes of ore to reduce unit costs, strengthening its asset base, continuing to increase its
mineral reserves and resources at each of its mines, and exploring organic and external growth opportunities to enhance and deliver
shareholder value.

2019 Operational Highlights and Growth Initiatives



During 2019, the annual consolidated production of silver,
copper, zinc, lead and gold increased 24%, 17%, 6%, 28% and 50% respectively. During Q4 2019, the Company achieved record consolidated
quarterly ore throughput, driven by record quarterly ore throughput from the Bolivar and Cusi Mines. These results continued the
Company’s successful production increases realized during the first three quarters of 2019, which resulted in strong annual
consolidated production figures.



Metal production at Yauricocha increased 43% in Q4 2019
compared to Q4 2018 due to 20% higher ore throughput, 19% higher zinc head grade, and higher recoveries for all metals. At Bolivar,
28% higher ore throughput, and higher silver and gold head grades resulted in a 49% increase in copper equivalent pounds produced
in Q4 2019 compared to Q4 2018. The Cusi Mine realized a 5% increase in throughput, 8% higher silver head grade offset by lower
lead and gold head grades which resulted in silver equivalent ounces production that was in line with Q4 2018.



2019 Consolidated Financial Highlights



- Revenue from metals payable of $229.0 million in 2019 decreased
by 1% from $232.4 million in 2018. Revenues were lower due to the impact of lower realized metal prices and higher treatment costs
related to zinc.



- Yauricocha’s cost of sales per zinc equivalent payable
pound was $0.48 (2018 - $0.55), cash cost per zinc equivalent payable pound was $0.46 (2018 - $0.52), and AISC per zinc equivalent
payable pound of $0.79 (2018 - $0.73). Lower cost of sales and cash costs resulted from higher production and consequent 21% higher
sale of zinc equivalent pounds as compared to 2018. Sustaining capital costs for the year were 79% higher than those in 2018, resulting
in higher AISC per zinc equivalent payable pound compared to 2018.



- Bolivar’s cost of sales per copper equivalent payable
pound was $2.03 (2018 - $1.73), cash cost per copper equivalent payable pound was $1.73 (2018 - $1.44), and AISC per copper equivalent
payable pound was $2.86 (2018 - $2.13). The increase in cost of sales and cash cost per copper equivalent pound resulted mainly
from higher operating costs during the year. The increase in AISC per copper equivalent payable pound during 2019 compared to 2018 was due to higher cash costs and higher sustaining costs during
the year;

5


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




- Cusi’s cost of sales per silver equivalent payable ounce was $13.35 (2018 -
                                                                             $8.97), cash cost per silver equivalent payable ounce was $21.38 (2018 - $15.71), and AISC per silver equivalent payable
                                                                             ounce was $30.89 (2018 - $22.09). Unit costs for 2019 were higher at Cusi compared to 2018, as the slight increase in silver
                                                                             equivalent payable ounces could not offset the increase in cost of sales and sustaining costs during the year;



- Adjusted EBITDA(1)
of $65.3 million for 2019, which is a 27% decrease from the adjusted EBITDA of $89.8 million for 2018. This decrease was a combined
result of the lower consolidated revenue and higher operating costs;



- Net income attributable
to shareholders for 2019 was $4.4 million (2018: $18.8 million) or $0.03 per share (basic and diluted) (2018: $0.12);



- Adjusted net income
attributable to shareholders (1) of $13.9 million, or $0.09 per share, for 2019 was lower than the adjusted net income
of $29.0 million, or $0.17 per share for 2018;



- A large component of the net income for every period is
the non-cash depletion charge in Peru, which was $10.3 million for 2019 (2018: $10.5 million). The non-cash depletion charge is
based on the aggregate fair value of the Yauricocha mineral property at the date of acquisition of Sociedad Minera Corona S.A.
de C.V. (“Corona”) of $371.0 million amortized over the total proven and probable reserves of the mine;



- Cash flow generated from operations before movements in
working capital of $66.4 million for 2019 decreased compared to $90.1 million in 2018. The decrease in operating cash flow is mainly
the result of lower revenues generated and lower gross margins realized; and



- Cash and cash equivalents of $43.0 million and working
capital of $49.9 million as at December 31, 2019 compared to $21.8 million and $(8.3) million, respectively, at the end of 2018.
Cash and cash equivalents increased by $21.1 million during 2019 due to $39.6 million of operating cash flows after taxes and changes
in working capital, and $99.8 million drawn down from a secured corporate credit facility from Banco de Credito del Peru (“BCP”),
being offset by capital expenditures incurred in Mexico and Peru of $54.6 million, repayment of loans, credit facilities and interest
of $60.9 million and share repurchased during the year for $2.8 million.

| | 4. | OUTLOOK
| | -- | -------

2019 was a pivotal year for the Company, as it achieved
some key milestones towards its future expansion in Mexico and Peru.



The Yauricocha Mine operated at a rate of 3,600 tpd in the
last quarter of 2019 to compensate for the loss of 24-day production due to the illegal strike in the first half of the year. Studies
are already underway to provide further clarity and confidence for further operational production increases, thereby achieving
economies of scales and offset the impact of soft metal prices and high treatment charges. The receipt of the Environmental Impact
Assessment (“EIA”) in 2019 is an important step in the future throughput expansion at Yauricocha. During the first
half of 2020, the Company expects to receive the permit for the next phase of the tailings deposition facility and the expanded
waste rock facility.



The Bolivar Mine achieved approximately 3,600 tpd
of mill throughput in 2019 due to the successful completion of plant expansions earlier during the year. Additional
improvements such as installation of three flash floatation cells and parallel
configuration of the mill allowed for approximately 4,000 tpd during the last quarter of 2019. In 2020, the Bolivar Mine is expected
to average 4,250 tpd during the first half of the year and reach an average of 5,000 tpd by the fourth quarter. Further, the Company
is expecting to press release the NI 43-101 Reserve and Resource update before 31 March 2020, followed by a PEA in the second half
of 2020, with the expectation to increase the Bolivar Plant capacity beyond the 5,000 tpd throughput rate.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




Milling capacity at the Cusi Mine has been expanded to 1,200
tpd. However, mine development was delayed in 2019 due to a subsidence event, triggered by excessive and water inflows, thus limiting
mill feed during the year. For 2020, the focus at the Cusi Mine is on the optimization of the underground mine for consistent mill
feed of about 1,200 tpd.



The Company has continued to be successful in maintaining
positive operating cash flow generation from its existing operations in order to reduce debt levels, fund required capital expenditures,
and maintain liquidity. The $100 million Corporate Credit Facility, finalized in March 2019, provides the Company with additional
liquidity and will provide the financial flexibility to fund future capital projects in Mexico as well as corporate working capital
requirements. The terms of this credit facility allow a grace period of two years, which implies no principal repayments until
June 2021. Further, the interest rate on this credit facility is 3-month LIBOR plus 3.15 %.



On January 23, 2020, the Company issued the following guidance

Due to the increasing number of coronavirus
(COVID-19) infections in the country, the Peruvian Government declared a state of emergency on March 17, 2020 for a period of 15
days to contain the advancement of the virus, which restricts travel within the country and requires citizens to remain at home
with the exception of some essential services. On March 26, 2020, the Peruvian Government extended the state of emergency for an
additional 13 days until April 12, 2020. As such, all mining activities and permitting submissions in Peru have also been halted.
This will result in a delay in all permits being issued. Pursuant to this declaration, the Company has also ceased its mining operations
at the Yauricocha Mine, with the exception of emergency staff, as permitted by the Government. Due to the uncertainty of the effect
that the COVID-19 Pandemic could have on the Company’s operations and financial condition, and due to rapidly changing developments,
the Company is currently implementing proactive and reactive mitigation measures to minimize any potential impacts COVID-19 may
have on its employees, communities, operations, supply chain, and finances. This also includes preserving capital and deferring
capital programs, where appropriate, to improve liquidity. The Company is maintaining its guidance due to the operating flexibility
at the Yauricocha Mine and the current normal operations of its Mexican mines. Should any material changes occur, the Company would
update its guidance promptly, and expects to provide a more comprehensive update with more data points on metal prices and operating
developments as part of the Q1 2020 reporting process.



Further, as noted in a previous press release dated January
8, 2020, in anticipation of free cash flows during the year, the Company was contemplating returning capital to its shareholders,
for which the Company’s board of directors (the “Board”) had approved a plan to return up to $30 million to shareholders
in the 2020, which represented a portion of the EBITDA guidance noted above. Due to the highly uncertain economic situation as
a result of COVID-19 and its impact on the Company’s operations and metal prices, the Company has also decided to postpone
its contemplated share repurchase program.



Market Review and Trends



Metal Prices



One of the primary drivers of Sierra’s earnings and
ability to generate operating cash flows are the metal market prices. In 2019, while silver and gold prices averaged 4% and 11%
over their 2018 averages, prices for copper, lead and zinc averaged 8%, 11% and 14% lower than the prices in 2018. Metal prices
have been impacted by the market uncertainty stemming from the U.S-China trade war and weakening growth in China — the world’s
largest consumer of metals.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)


Gold and silver had a stellar year, as the prices continued
to grow throughout the year, except a slight decline in Q2 2019. Macro-environment and geo-political concerns, as always, have
been the key drivers for gold and silver. After raising the interest rates four times in 2018, the Federal Reserve took a pause
and gradually decreased interest rates three times in 2019, which impacted precious metals such as gold and silver positively.
Sierra’s average realized silver price for 2019 was $16.29 per ounce compared to $15.65 per ounce in 2018. Sierra’s
average realized gold price for 2019 was $1,404 per ounce compared to $1,269 per ounce in 2018.



Copper prices have been at the mercy of the US-China trade
war during 2019, which pulled and pushed the metal price throughout the year. Q1 2019 was riddled with the concerns over potential
copper supply shortage, helping prices to rise marginally over Q4 2018. This trend continued for part of Q2 2019, but the trade
tensions between US and China started pressurizing the prices lower. The introduction of significant tariffs over Chinese goods
added further pressure on an already slowing global macroeconomic outlook for the year. Copper had a turbulent third quarter, with
prices heating up during July, as both US and Chinese manufacturers reported lower-than-projected numbers, only to fall dramatically
by September, as the US-China trade talks continued to stall. Copper was the best-performing base metal in Q4 2019, as a tentative
trade deal and easing of tariffs helped prices. London Metal Exchange (LME) copper prices in the fourth quarter of 2019 averaged
$2.69 per pound, up 2% from the third quarter, yet below the annual average price of $2.96 per pound in 2018. Annual prices in
2019 averaged $2.73 per pound, down 8% from 2018 averages. Sierra’s average realized copper price for 2019 was $2.73 per
pound compared to $2.96 per pound in 2018.



Zinc prices trended upwards in the first quarter of 2019
mainly as a result of supply constraints. Stockpiles of the base metal at LME warehouses fell to their lowest levels in over two
decades during this period. Furthermore, Chinese production remained subdued, largely reflecting stricter environmental regulations
faced by smelters, thus accentuating the supply shortage in the market. However, zinc prices slipped after April, partly due to
signs of slowing global growth, along with the perpetually turbulent relationship between China and the United States. Sierra’s
realized zinc price for 2019 was $1.14 per pound compared to $1.31 per pound in 2018.



Lead prices traded in a range of $0.85 to $0.94 per pound
in 2019. Sierra’s realized lead price during 2019 was $0.91 per pound compared to $1.02 per pound in 2018.



Currency Exchange Rates



The results of Sierra’s operations are affected by
US dollar exchange rates. Sierra’s largest exposures are to the US dollar/Peruvian Nuevo Sol exchange rate and the US dollar/Mexican
Peso exchange rate which impacts operating and administration costs in Peru and Mexico incurred in Nuevo Soles and Pesos while
revenues are earned in US dollars. As at December 31, 2019 the US dollar/Peruvian Nuevo Sol exchange rate was 3.32 (December 31,
2018: 3.38) and the US dollar/Mexican Peso exchange rate was 18.87 (December 31, 2018: 19.64). A 10% change in the value of the
Nuevo Sol and Peso against the US dollar would have resulted in a change of $1.0 million and $1.1 million in the Company’s
net profit, respectively, assuming that our operational performance during 2019 was consistent with 2018.



The Company also has a minor exposure to the Canadian dollar
through corporate administrative costs.

The Peruvian Operation



Yauricocha Mine, Yauyos Province



Corona’s main asset, Yauricocha, is an underground
mine located in western central Peru in the Yauyos province, approximately 12 km west of the Continental Divide. The Yauricocha
property covers 18,778 hectares that straddle a 20 km strike length of the prolific Yauricocha fault, a major ore controlling structure
in this part of western central Peru. The mine is at an average altitude of 4,600 meters and has been producing for more than 68
years. Ore is processed at the on-site Chumpe plant using a combination of crushing, grinding and flotation and is permitted to
produce at a rate of 3,150 tpd, which we expect to increase to 3,600 tpd during 2020 upon receipt of the ITS permit. The ore is
treated in two separate circuits and is extracted from three different types of deposits which include the following:



| | - | A polymetallic deposit, containing
silver, lead, zinc, copper, and gold
| | - | -----------------------------------------------------------------------

| | - | A lead oxide deposit, containing lead,
silver and gold
| | - | ------------------------------------------------------

| | - | A copper oxide deposit, containing
copper, silver, lead and gold
| | - | ----------------------------------------------------------------



During 2019, the Company continued to explore the copper-molybdenum
porphyry, starting at the 720 level of the Klepetco tunnel using 3 diamond drills. Drill core returned from the holes intercepted
zones of porphyry style mineralization.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)


Previous evidence of porphyritic copper-molybdenum mineralization
had already been observed within the intrusive monzonite and had already been examined by Rio Tinto, performing geochemical sampling
in the Klepetco tunnel. The results of diamond drilling are quite encouraging and demonstrate the presence of the porphyry copper-molybdenum.
The areas of the anomalies of the Titan-24 geophysics are demonstrating a strong correlation between conductivity response with
the mineralized bodies, which helps in understanding the magnitude of mineralization and helps relate the discoveries of mineralized
bodies in Yauricocha, thus making the exploration objectives clearer.

The Yauricocha Mine production increased
despite the negative impact of the 28-day illegal strike in the first half of 2019. The Mine processed a total of 1,116,919 tonnes
during 2019, representing an 1% increase from 2018, and 321,701 tonnes in Q4 2019, representing a 20% increase compared to Q4 2018.
Zinc equivalent metal production in Q4 2019 increased by 43% due to higher ore throughput, higher head grades for zinc (19%), lead
and gold, and higher recoveries for all metals. The higher zinc head grade and zinc production realized during Q4 2019 was the
result of increased production from the high-grade small ore bodies (“cuerpos chicos”).



Year over year zinc equivalent production
was 19% higher in 2019 compared to the prior year. During 2019, the annual production of silver, copper, zinc, lead and gold increased
15%, 20%, 6%, 30% and 22% respective to 2018.

The Mexican Operations



Bolivar Mine, Chihuahua State



The Bolivar Mine is a contiguous portion of the 15,217 hectare
Bolívar Property land package within the municipality of Urique, in the Piedras Verdes mining district of Chihuahua State,
Mexico. During 2012, the Company achieved its first full year of commercial production at the Piedras Verdes plant, which is located
6 kilometres from the Bolivar Mine that had an initial capacity of 1,000 tpd. In September 2013, the
Piedras Verdes plant further increased its daily throughput capacity to 2,000 tpd by installing a new circuit. The expansion of
the plant, which included installation of a refurbished mill, an electrical substation with 1250 KVA of capacity, a secondary crusher
and a hydrocyclone cluster was completed in the first quarter of 2019. This helped grind size optionality and consequent improved
copper recoveries at the plant. Mill throughput during the fourth quarter of 2019 averaged almost 4,000 tpd, resulting in planned
annual production of 3,600 tpd for the year.



In Bolívar during the fourth quarter of 2019, 5,526
meters were drilled from the surface, as well as diamond drilling inside the mine. 159 meters were drilled inside the mine in the
Lower Gallo area. On the surface, 4,149 meters were drilled in Bolívar West to explore the extent of the deposit, exploring
the skarn deposit with semi-massive magnetite and scattered chalcopyrite nodules. 1,218 meters were also drilled from inside the
West Bolivar Mine looking for evidence of the Cu-Mo Porphyry.



Bolivar Mineral Resource Update



On December 31, 2019, the Company provided an update
to its Mineral Resource Estimate for the Bolivar Mine. This update was a result of drilling programs completed between November
2017 and September 2019, as well as production data up to September 2019; this Mineral Resource update includes 13,698 metres
of infill drilling and 41,553 metres of exploration drilling.



Mineral Resource Estimations have been conducted by Cliff
Revering, P.Eng of SRK Consulting (Canada.) Inc., a Qualified Person under NI 43-101, using Maptek VulcanTM and Leapfrog GeoTM
software.

The Bolivar Mine processed 1,269,697
tonnes in 2019, representing a 23% increase over 2018. The average daily ore throughput realized during the fourth quarter was
approximately 4,000 tpd, reaching 4,682 tpd for the month of December 2019, exceeding the 4,250 tpd target. Q4 2019 record throughput
was 348,434 tonnes, which was 28% higher when compared to Q4 2018. The higher throughput and higher gold and silver head grades
resulted in a 49% increase in copper equivalent production in Q4 2019 compared to Q4 2018, despite the 2% reduction in copper grades.
The development work performed during the year by increasing the ramps and access drives resulted in increased access to more minable
stopes which also contributed to the higher throughput. The Company is pleased with the progress made on the expansion plans at
the Bolivar Mine with production expected to increase steadily in 2020, reaching approximately 5,000 tpd by Q4 2020. The Bolivar
West zone is now contributing to approximately 40% of ore production and is expected to increase to 50% during 2020.



Copper equivalent production at the Bolivar
Mine increased 28% in 2019 compared to 2018, with copper production 15% higher, silver production 42% higher, and gold production
76% higher. In Q4 2019, copper production increased by 34% to 5,659,000 pounds, silver production increased 44% to 185,000 ounces,
and gold production increased 91% to 2,216 ounces compared to Q4 2018. The significantly higher silver and gold production is due
to higher silver and gold head grades in the Bolivar West zone, as compared to the El Gallo zone. The 49% increase in copper equivalent
production was driven by higher throughput, and higher silver and gold head grades.





Cusi Mine, Chihuahua State



The Company’s Cusi Mine encompasses 73 concessions
covering 11,977 hectares that include 12 historical mines, each located on a mineralized structure, which lie within 40 kilometers
of the Malpaso Plant located in Chihuahua State, Mexico. On January 1, 2013 the Company announced that the Cusi Mine achieved
commercial production.

At Cusi, 4,920.35 meters were drilled during Q4 2019
to support the development of the Santa Rosa de Lima vein and Promontorio to further verify the size and continuity of the ore
zone.

(1) Silver equivalent ounces and copper and zinc equivalent
pounds for Q4 2019 were calculated using the following realized prices: $17.42/oz Ag, $2.69/lb Cu, $0.92/lb Pb, $1.07/lb Zn, $1,506/oz
Au. Silver equivalent ounces and copper and zinc equivalent pounds for Q4 2018 were calculated using the following realized prices:
$14.63/oz Ag, $2.77/lb Cu, $0.89/lb Pb, $1.16/lb Zn, $1,238/oz Au. Silver equivalent ounces and copper and zinc equivalent pounds
for 12M 2019 were calculated using the following realized prices: $16.29/oz Ag, $2.73/lb Cu, $0.91/lb Pb, $1.14/lb Zn, $1,404/oz
Au. Silver equivalent ounces and copper and zinc equivalent pounds for 12M 2018 were calculated using the following realized prices:
$15.65/oz Ag, $2.96/lb Cu, $1.02/lb Pb, $1.31/lb Zn, $1,269.





Annual production at the
Cusi Mine was 285,236 tonnes in 2019, which was 53% higher than 2018. Total ore processed increased by 5% to 61,365 tonnes during
Q4 2019 compared to Q4 2018. The higher throughput was partially offset by lower head grades and recoveries for all metals, which
resulted in a 1% increase in silver equivalent production in Q4 2019 compared to Q4 2018.



Silver equivalent production
increased 27% during 2019 compared to 2018, as silver production increased 34% to 936,000 ounces, gold production increased 32%
to 493 ounces and lead production decreased 24% to 904,000 pounds. There was no zinc production during the year compared to 71,000
pounds in 2018. However, during Q4 2019, silver production was 11% higher while gold and lead production were 38% and 45% lower
than Q4 2018, respectively.

Net income attributable to shareholders for 2019 was $4.4
million (2018: $18.8 million) or $0.03 per share (basic and diluted) (2018: $0.12). The other major differences between these periods
are explained below.



Revenues



Net revenue from metals payable at the Yauricocha Mine in
Peru of $156.0 million for 2019 decreased by 8% compared to $168.7 million of revenues in 2018 primarily due to the increase of
zinc treatment and refining costs. During 2019, the annual sales quantities of silver, copper, zinc, lead and gold increased 19%,
19%, 4%, 31% and 107% respective to 2018. Average realized sale price for silver and gold increased by 2% and 9%, while those for
copper, lead and zinc decreased by 7%, 7% and 14% respectively, as compared to 2018.



Net revenue from metals payable in Mexico increased to $73.1
million for 2019 from $63.7 million in 2018, driven mainly by the increase in silver sales quantity by 20% at Bolivar and 19% at
Cusi, as compared to 2018. Average realized sale price per ounce for silver also increased by 18% and 19% at Bolivar and Cusi respectively.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




The following table shows the Company’s realized selling
prices for each quarter in 2019 and 2018:



|Realized Metal Prices |  | 2019 |       |  | 2018 |  
|--------------------- |  | ---- | ----- |  | ---- | -
|(In US dollars)       |  | Q4   |       |  | Q3   |  
|Silver (per oz)       |  | $    | 17.42 |  |      | $
|Copper (per lb)       |  | $    | 2.69  |  |      | $
|Lead (per lb)         |  | $    | 0.92  |  |      | $
|Zinc (per lb)         |  | $    | 1.07  |  |      | $
|Gold (per oz)         |  | $    | 1,506 |  |      | $



Yauricocha’s cost of sales per zinc equivalent payable
pound was $0.49 (2018 - $0.55), cash cost per zinc equivalent payable pound was $0.47 (2018 - $0.52), and AISC per zinc equivalent
payable pound of $0.80 (2018 - $0.73). Lower cash costs resulted from 43% higher equivalent zinc pounds. Cash costs for the year
included $1.6 million of charges related to the illegal strike in Q1 2019. The increase in the AISC per zinc equivalent payable
pound for 2019 compared to 2018 was a result of higher sustaining capital expenditures offset by the impact of higher zinc equivalent
payable pounds. Sustaining costs of $12.9 million were higher than $7.3 million spent in 2018 and comprised mainly of $5.3 million
of development costs, $3.9 million of mining equipment, $2.2 million for ventilation and $1.5 million for other mine and mill improvements.



Bolivar’s cost of sales per copper equivalent payable
pound was $2.03 (2018 - $1.73), cash cost per copper equivalent payable pound was $1.73 (2018 - $1.44), and AISC per copper equivalent
payable pound was $2.86 (2018 - $2.13) for 2019. Increase in cash costs at Bolivar was a result of high-cost development using
contractors. The increase in AISC per copper equivalent payable pound during 2019 compared to 2018 resulted from higher cash costs
and higher sustaining costs. Sustaining capital for the year was $10.3 million, which included development costs of $4.1 million,
mine improvements and equipment of $2.0 million, milling equipment of $3.8 million and $0.4 million of sustaining exploration costs.



Cusi’s cost of sales per silver equivalent payable
ounce was $13.35 (2018 - $8.97), cash cost per silver equivalent payable ounce was $21.39 (2018 - $15.71), and AISC per silver
equivalent payable ounce was $30.89 (2018 - $22.09) for 2018. Total cost of sales and sustaining costs at Cusi increased during
the year, while equivalent silver ounces almost in line with 2018. Sustaining costs at Cusi were $4.3 million, which included mine
and mill equipment $2.5 million, tailings dam costs of $0.9 million and $0.9 million of sustaining exploration costs.





Non-Cash Depletion, Depreciation and
Amortization



The Company recorded total non-cash depletion, depreciation
and amortization expense for 2019 of $36.1 million compared to $31.4 million for the same period in 2018.



A large component of the net income for every period is
the non-cash depletion charge in Peru, which was $10.3 million for 2019 (2018: $10.5 million). The non-cash depletion charge is
based on the aggregate fair value of the Yauricocha mineral property at the date of acquisition of Corona of $371.0 million amortized
over the total proven and probable reserves of the mine.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




General and Administrative Expenses



The Company incurred general and administrative expenses
of $19.5 million in 2019 compared to $18.9 million in 2018. The 3% increase in general and administrative costs in 2019 compared
to 2018 resulted mainly from increase in salaries and benefits offset by a decrease in consultancy and professional fees.



Adjusted EBITDA (1)



The Company recorded adjusted EBITDA of $65.3 million during
2019 (2018: $89.8 million) which includes $60.2 million (2018: $79.5 million) from the Peruvian operations and $9.2 million (2018:
$13.8 million) from the operations in Mexico. The decrease in adjusted EBITDA is due to the decrease in net revenues and higher
costs at the Mexican operations. Adjusted EBITDA is a non-IFRS measure that represents an indication of the Company’s continuing
capacity to generate earnings from operations before taking into account management’s financing decisions and costs of consuming
capital assets, which vary according to their vintage, technological currency, and management’s estimate of their useful
life. Adjusted EBITDA comprises revenue less operating expenses before interest expense (income), property, plant and equipment
amortization and depletion, foreign exchange variations, non-recurring provisions, share-based payments expense, and income taxes.
The Company considers cash flow before movements in working capital to be the IFRS performance measure that is most closely comparable
to adjusted EBITDA.

Income Taxes



The Company recorded current tax expense of $17.4 million
for 2019 compared to $24.4 million in 2018. The decrease was the result of the lower taxable income generated at both sites during
2019 compared to 2018.



During 2019, the Company recorded a deferred tax recovery
of $4.9 million compared to $0.9 million deferred tax expense in 2018. The main driver for the Company’s consolidated deferred
tax recovery is the non-cash recovery associated with the acquisition of Corona which has decreased period over period, in line
with the non-cash depletion charge mentioned previously.

Adjusted Net Income Attributable to
Shareholders (1)



Adjusted net income attributable to shareholders (1)of $13.9 million, or $0.09 per share, for 2019 was lower than the adjusted net income of $29.0 million, or $0.17 per share
for 2018. Adjusted net income is defined by management as the net income attributable to shareholders shown in the condensed interim
consolidated statements of income excluding the non-cash depletion charge due to the acquisition of Corona, the corresponding
deferred income tax recovery, and certain non-recurring or non-cash items. Accordingly, management considers this metric to be
more meaningful to measure the Company’s profitability than net income as it adjusts for specific non-cash items.



Other Comprehensive Income



Other comprehensive income (“OCI”) for 2019
was $10.0 million compared to OCL of $24.3 million in 2018. OCI includes a foreign currency gain of $0.7 million for 2019 (2018:
$(1.6) million). The unrealized foreign currency translation gain was caused by the strengthening of the Canadian dollar relative
to the US dollar during the period which resulted in a foreign exchange gain on the translation of the Canadian dollar net assets
into the Company’s US dollar presentation currency.

Measures section of this MD&A.



Cash Flows



Cash flow generated from operations before movements in
working capital of $66.4 million for 2019 decreased compared to $90.1 million in 2018. The decrease in operating cash flow is mainly
the result of lower revenues generated and lower gross margins realized, attributable higher operating costs.



Net cash flow of $(54.6) million (2018: $(49.3) million)
used in investing activities during 2019 consists of purchases of property, plant and equipment, capital expenditures related to
the Yauricocha shaft and tunnel development, and exploration and evaluation assets in Peru and Mexico.



A breakdown of the Company’s capital expenditures
of $54.6 million during the year ended December 31, 2019 is presented below:

Three months ended December 31, 2019 (compared to the three months ended December
31, 2018)



Net income attributable to shareholders for Q4 2019 was
$4.5 million, or $0.03 per share (basic and diluted), compared to net income of $(2.7) million, or $(0.01) per share (basic and
diluted) for the same period in 2018. The major differences between these periods are explained below.



Revenues



Revenues from metals payable from the Yauricocha Mine in
Peru were $42.2 million for Q4 2019 compared to $39.2 million in Q4 2018. The increase in revenues for Q4 2019 compared to Q4 2018
was due to a 20% increase in tonnes processed, higher head grades for all metals, except silver, and higher recoveries for all
metals. Increased revenues were realized due to the higher metal production, despite decreases in the prices of zinc (8%) and copper
(3%), and despite approximately 4,160 tonnes of unsold concentrate at year end.



Revenue from metals payable in Bolivar was $20.0 million
for Q4 2019, compared to $12.0 million for the same period in 2018, driven higher by 28% increase in throughput and higher silver
prices, offset by the impact of lower copper prices.



Revenues generated at the Cusi Mine for Q4 2019 were $2.8
million compared to $3.8 million for Q4 2018. Although throughput was 5% higher in Q4 2019 as compared to Q4 2018, grades were
lower (except silver) and recoveries were lower for all metals. Grades continued to be affected by the delayed development resulting
from heavy rains and subsidence during the previous quarter.



Yauricocha’s cost of sales per zinc equivalent payable
pound was $0.44 (Q4 2018 - $0.54), cash cost per zinc equivalent payable pound was $0.46 (Q4 2018 - $0.52), and AISC per zinc equivalent
payable pound of $0.83 (Q4 2018 - $0.73). Lower cost of sales per pound and cash costs per pound resulted from a 37% increase in
the number of zinc equivalent pound sold during the quarter as compared to the same quarter of 2018. Sustaining costs were higher
during the quarter mainly due to timing of expenditures and included $2.5 million of development costs, $2.3 million of mine equipment
and $0.8 million of other mine and mill improvements.



25


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)






Bolivar’s cost of sales per copper equivalent
payable pound was $2.44 (Q4 2018 - $2.11), cash cost per copper equivalent payable pound was $2.06 (Q4 2018 - $1.67), and AISC
per copper equivalent payable pound was $2.92 (Q4 2018 - $2.37) for Q4 2018. The increase in the AISC per copper equivalent payable
pound during Q4 2019 compared to Q4 2018 was due to higher cash costs and treatment and refining costs offset partially by higher
number of copper equivalent ounces sold.



Cusi’s cost of sales per silver equivalent payable
ounce was $25.29 (Q4 2018 - $11.04), cash cost per silver equivalent payable ounce was $42.12 (Q4 2018 - $18.96), and AISC per
silver equivalent payable ounce was $56.84 (Q4 2018 - $23.27) for Q4 2019. Higher costs at Cusi resulted from higher cost of operations
per tonnes mill and lower silver equivalent payable ounce. Sustaining costs were also higher during the quarter as compared to
the same quarter of 2018.





Non-Cash Depletion, Depreciation and
Amortization



The Company recorded total non-cash depletion, depreciation
and amortization expense for Q4 2019 of $9.2 million compared to $8.0 million for the same period in 2018.



A large component of the non-cash depletion, depreciation
and amortization expense is the depletion charge on the acquisition of Corona of $2.7 million for Q4 2019 compared to $2.5 million
for the same period in 2018. The non-cash depletion charge is based on the aggregate fair value of the Yauricocha mineral property
at the date of acquisition of Corona of $371.0 million amortized over the total proven and probable reserves of the mine.



General and Administrative Expenses



The Company incurred general and administrative expenses
of $5.2 million for Q4 2019, slightly higher than $5.0 million for Q4 2018.



Adjusted EBITDA



Adjusted EBITDA(1) for Q4 2019 was $19.1 million,
an increase of 25% compared to $15.3 million in Q4 2018. The increase in adjusted EBITDA was a result of higher revenues during
the quarter, as higher quantities of silver (6%), copper (10%), lead (20%), zinc (34%), and gold (83%) were sold during as compared
to Q4 2018.



Income Taxes



The Company recorded current tax expense of $5.2 million
for Q4 2019 compared to $5.3 million in Q4 2018. Current taxes were almost in-line with Q4 2018 as a result of the similar taxable
income generated during the quarter.



During Q4 2019, the Company recorded a deferred tax recovery
of $3.4 million compared to a deferred tax expense of $1.3 million in Q4 2018. The main driver for the Company’s consolidated
deferred tax recovery is the non-cash recovery associated with the acquisition of Corona which has decreased year over year in
line with the non-cash depletion charge mentioned previously.



26


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)








Adjusted Net Income Attributable to Shareholders



The Company recorded an adjusted net income of $7.2 million
for Q4 2019 compared to $0.8 million for Q4 2018. Adjusted net income is defined by management as the net income attributable to
shareholders shown in the condensed interim consolidated statements of income excluding the non-cash depletion charge due to the
acquisition of Corona, the corresponding deferred income tax recovery, and certain non-recurring or non-cash items. Accordingly,
management considers this metric to be more meaningful to measure the Company’s profitability than net income as it adjusts
for specific non-cash items.



Other Comprehensive Income (Loss)



OCI for Q4 2019 was $5.4 million compared to OCI of $(2.8)
million for the same period in 2018. OCI includes a foreign currency gain of $0.5 million in Q4 2019 (Q4 2018: $(1.1) million).
The unrealized foreign currency translation gain was caused by the strengthening of the Canadian dollar relative to the US dollar
during the quarter, which resulted in a foreign exchange gain on the translation of the Canadian dollar net assets into the Company’s
US dollar presentation currency.

Cash and cash equivalents of $43.0 million and working capital
of $49.9 million as at December 31, 2019 compared to $21.8 million and $(8.3) million, respectively, at the end of 2018. Cash and
cash equivalents increased by $21.1 million during 2019 due to $39.6 million of operating cash flows after taxes and changes in
working capital, and $99.8 million drawn down from a secured corporate credit facility from BCP, being offset by capital expenditures
incurred in Mexico and Peru of $54.6 million, repayment of loans, credit facilities and interest of $60.9 million and share repurchased
during the year for $2.8 million.



Trade and other receivables include $9.2 million (December
31, 2018 - $5.8 million) of Mexican value-added tax (“VAT”) receivables. The increase in VAT receivables is largely
due to the process to recover taxes being slowed down by the Government. The Company expects to collect or offset the VAT balance
against 2019 VAT payables. Amounts included in trade and other receivables are current and the Company has no allowance for doubtful
accounts as at December 31, 2019.

Financial Risk Management



The Company is exposed to financial risks, including credit
risk, liquidity risk, currency risk, interest rate risk and price risk. The aim of the Company’s overall risk management
strategy is to reduce the potential adverse effect that these risks may have on the Company’s financial position and results.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)






The Company’s Board of Directors has overall responsibility
and oversight of management’s risk management practices. Risk management is carried out under policies approved by the Board
of Directors. The Company may from time to time, use foreign exchange contracts, future and forward contracts to manage its exposure
to fluctuations in foreign currency and metals prices. The Company does not ordinarily enter into hedging arrangements to cover
long term commodity price risk unless it has the obligation to do so
under a credit facility, which would be approved by the Board of Directors.



| | (a) | Market Risk
| | --- | -----------



| | (i) | Currency Risk
| | --- | -------------



Currency risk is the risk that the fair
values or future cash flows of the Company’s financial instruments will fluctuate because of changes in foreign exchange
rates. The Company and its subsidiaries’ financial instruments are exposed to currency risk where those instruments are
denominated in currencies that are not the same as their functional currency; exchange gains and losses in these situations impact
net income or loss. The Company’s sales of silver, copper, lead and zinc are denominated in United States dollars and the
Company’s costs are incurred in Canadian dollars, United States dollars, Mexican pesos and Peruvian Nuevo Soles. The United
States dollar is the functional currency of the Peruvian and Mexican entities. The Canadian dollar is the functional currency
of all other entities. The Company also holds cash and cash equivalents, trade and other receivables, accounts payable and other
liabilities that are subject to currency risk.



The following are the most significant areas of exposure to currency risk:

The Company manages and monitors
this risk with the objective of mitigating the potential adverse effect that fluctuations in currencies against the Canadian dollar
and US dollar could have on the Company’s Consolidated Statement of Financial Position and Consolidated Statement of income
(loss). As at December 31, 2019, the Company has not entered into any derivative contracts to mitigate this risk.



A 10% appreciation in the US dollar exchange
rate against the Peruvian Nuevo Soles and the Mexican Peso based on the financial assets and liabilities held at December 31, 2019,
with all the other variables held constant, would have resulted in an increase to the Company’s net income of $2,053 (increase
in income in 2018 of $1,992).



A 10% appreciation in the Canadian dollar
exchange rate against the US dollar based on the financial assets and liabilities held at December 31, 2019 and 2018, with all
the other variables held constant, would have resulted in a negligible impact to the Company’s net income (loss).



| | (ii) | Interest Rate Risk
| | ---- | ------------------



Interest rate risk is the risk that the fair
values or future cash flows of the Company will fluctuate because of changes in market interest rates. The Company is exposed to
interest rate risk on its loans payable (note 10). The Company monitors its exposure to interest rates closely and has not entered
into any derivative contracts to manage its risk. The weighted average interest rate paid by the Company during the year ended
December 31, 2019 on its loans and notes payable in Peru was 5.58% (2018 – 4.26%). With all other variables unchanged a 1%
increase in the interest rate would have increased the Company’s net loss by $690 (2018 - $486).



| | (iii) | Commodity
Price Risk
| | ----- | --------------------



Commodity price risk is the risk that the
fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices (other than those
arising from interest risk or currency risk), whether those changes are caused by factors specific to the individual financial
instrument or its issuer, or factors affecting all similar financial instruments in the market.



30


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




As at December 31, 2019 and 2018, the Company
had certain amounts related to the sales of concentrates that have only been provisionally priced. Commodity price risk exists
solely in Mexico as the Company fixes metal prices with the purchaser of its concentrates for specific sales for which concentrates
have been delivered. The Company’s exposure to commodity price risk is as follows:



|                                 |  | 2019 |      |   | 2018 |

|10% decrease in gold prices      |  |      | (323 | ) |      | 



As at December 31, 2019 and 2018, the Company
did not have any forward contracts outstanding.



| | (b) | Liquidity Risk
| | --- | --------------



Liquidity risk is the risk that the Company
will not be able to meet its financial obligation as they fall due. The Company has in place planning, budgeting and forecasting
process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis and
its expansion and development plans. The Company tries to ensure that it has sufficient committed credit facilities to meet its
short-term operating needs.



In the normal course of business, the Company
enters into contracts that give rise to commitments for future minimum payments. The following table summarizes the remaining contractual
maturities and undiscounted cash flows as at December 31, 2019 of the Company’s financial liabilities and operating and capital
commitments:



|                                         |  | Within 1 year |        |  | 1-2 years |  |        | 2-5 years |  |  | After 5 years |  |  | As at  December 31, |

In the opinion of management, the working
capital at December 31, 2019, together with future cash flows from operations and available loan facilities, is sufficient to support
the Company’s commitments through 2020.



| | (c) | Credit Risk
| | --- | -----------



Credit risk is the risk that the counterparty
to a financial instrument might fail to discharge its obligations under the terms of a financial contract. Credit risk is primarily
associated with trade receivables; however, it also arises on cash and cash equivalents. The Company sells its concentrate to large
international organizations. The Company is exposed to significant concentration of credit risk given that all of its revenues
from Peru and Mexico were from two customers at each of the locations. At December 31, 2019 and 2018 the Company has not recorded
an allowance against trade receivables because it is confident that all of the balances will be collected in full when due and
there have not been any issues collecting balances owed to the Company in the past.



31


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




The Company’s policy is to keep its
cash and cash equivalents only with highly rated financial institutions and to only invest in government securities. The Company
considers the risk of loss associated with cash and cash equivalents to be low. The counterparty to the financial asset is a large
international financial institution with strong credit ratings and thus the credit risk is considered to be low.



| | 11. | OTHER RISKS AND UNCERTAINTIES
| | --- | -----------------------------

Foreign Operations



The Company currently conducts foreign operations and has
exploration properties in Peru and Mexico, and as such is exposed to various levels of economic, political and other risks and
uncertainties. These risks and uncertainties vary from country to country and include, but are not limited to, royalties and tax
increases or claims by governmental bodies, expropriation or nationalization, foreign exchange controls, import and export regulations,
cancellation or renegotiation of contracts and environmental permitting regulations. The occurrence of these various factors and
uncertainties cannot be accurately predicted and could have a material adverse effect on operations or profitability.



The Company currently has no political risk insurance coverage
against these risks. The Company is unable to determine the impact of these risks on its future financial position or results of
operations. Changes, if any, in mining or investment policies or shifts in political attitude in foreign countries may substantively
affect Company’s exploration, development and production activities.



Environmental Regulation



The Company’s activities are subject to extensive
laws and regulations governing environmental protection which are complex and have tended to become more stringent over time. The
Company is required to obtain governmental permits and, in some instances, provide bonding requirements under federal, state, or
provincial air, water quality, and mine reclamation rules and permits. Although the Company makes provisions for reclamation costs,
it cannot be assured that these provisions will be adequate to discharge its future obligations for these costs. Failure to comply
with applicable environmental laws may result in injunctions, damages, suspension or revocation of permits and imposition of penalties.
While responsible environmental stewardship is one of the Company’s top priorities, there can be no assurance that the Company
has been or will be at all times in complete compliance with such laws, regulations and permits, or that the costs of complying
with current and future environmental laws and permits will not materially and adversely affect the Company’s business, results
of operations or financial condition.





32


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)






Exploration, Development and Mining Risk



Sierra’s operations will be subject to all the hazards
and risks normally encountered in the exploration, development and production of base or precious metals, including, without limitation,
unusual and unexpected geologic formations, seismic activity, rock bursts, pit-wall failures, cave-ins, flooding, mud-rushes and
other conditions involved in the drilling, mining and removal of material, any of which could result in damage to, or destruction
of, mines and other producing facilities, damage to life or property, environmental damage and legal liability. Milling operations
are also subject to various hazards, including, without limitation, equipment failure and failure of retaining dams around tailings
disposal areas, which may result in environmental pollution and legal liability.



Loan Repayment Risk



The Company’s ability to repay its loans depends
on its future cash flows, profitability, results of operations and financial condition. The Company has prepared budgets based
on estimates of commodity prices, future production, operating costs and capital costs however the Company cannot assure you that
such revenues, production plans, costs or other estimates will be achieved. Actual revenues and production costs may vary from
the estimates depending on a variety of factors, many of which are not within the Company’s control. These factors include,
but are not limited to: commodity price fluctuations; actual ore mined varying from estimates of grade, tonnage, dilution, and
metallurgical and other characteristics; mine failures, slope failures or equipment failures; industrial accidents; natural phenomena
such as inclement weather conditions, floods, droughts, rock slides and earthquakes; encountering unusual or unexpected geological
conditions; changes in power costs and potential power shortages; exchange rate and commodity price fluctuations; shortages of
principal supplies needed shortages of principal supplies needed for operations, including explosives, fuels, chemical reagents,
water, equipment parts and lubricants; labor shortages or strikes; high rates of inflation; civil disobedience and protests; and
restrictions (including change to the taxation regime) or regulations imposed by governmental or regulatory authorities or other
changes in the regulatory environments. Failure to achieve revenue, production or cost estimates or material increases in costs
or material decreases in commodity prices could have a material adverse impact on the Company’s future cash flows, profitability,
results of operations and financial condition.



Title Risk



Although the Company believes that it has exercised commercially
reasonable due diligence with respect to determining title to properties that it owns or controls, there is no guarantee that title
to such properties will not be challenged or impugned. The Company’s properties may be subject to prior unrecorded agreements
or transfers or native land claims and title may be affected by undetected defects. There may be valid challenges to the title
of the Company’s properties which could impair development and/or operations of the Company.





33


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




Permit Risk



In the ordinary course of business, the Company will be
required to obtain and renew governmental permits and licenses for the operation and expansion of existing operations or for the
commencement of new operations. Obtaining or renewing the necessary governmental permits is a complex and time-consuming process.
The duration and success of the Company’s efforts to obtain and renew permits and licenses are contingent upon many variables
not within its control including the interpretation of applicable requirements implemented by the permitting or licensing authority.
The Company may not be able to obtain or renew permits and licenses that are necessary to continue its operations or the cost to
obtain or renew permits and licenses may exceed what the Company expects. Any unexpected delays or costs associated with the permitting
and licensing process could delay the development or impede operations, which may adversely affect the Company’s revenues
and future growth.





Estimates of Mineralized Materials are Subject to Geologic
Uncertainty and Inherent Sample Variability



Although the estimated resources have been delineated with
appropriately spaced drilling and sampling, both underground and surface, there is inherent variability between duplicate samples
taken adjacent to each other and between sampling points that cannot be reasonably eliminated. There also may be unknown geologic
details that have not been identified or correctly appreciated at the current level of delineation. This results in uncertainties
that cannot be reasonably eliminated from the estimation process. Some of the resulting variances can have a positive effect and
others can have a negative effect on mining and processing operations. Acceptance of these uncertainties is part of any mining
operation.



Estimates of mineralized material constitute forward-looking
information, which is inherently subject to variability. Although resource estimates require a high degree of assurance in the
underlying data when the estimates are made, unforeseen events and uncontrollable factors can have significant adverse or positive
impacts on the estimates. Actual results will inherently differ from estimates. The unforeseen events and uncontrollable factors
include geologic uncertainties including inherent sample variability, metal price fluctuations, variations in mining and processing
parameters, and adverse changes in environmental or mining laws and regulations. The timing and effects of variances from estimated
values cannot be accurately predicted.



Mineral Resources



Although the Company’s reported mineral resources
have been carefully prepared by qualified persons, these amounts are estimates only by independent geologists, and the Company
cannot be certain that any specified level of recovery of mineral will in fact be realized or that any identified mineral deposit
will ever qualify as a commercially mineable (or viable) ore body that can be economically exploited. Mineralized materials, which
are not mineral reserves, do not have demonstrated economic viability. Any material change in the quantity of mineralization, grade
or stripping ratio, or the metal price may affect the economic viability of the Company’s properties. In addition, the Company
cannot be certain that metal recoveries in small-scale laboratory tests will be duplicated in larger scale tests under on-site
conditions or during production.



Until an un-mined deposit is actually mined and processed,
the quantity of mineral resources and reserves and grades must be considered as estimates only. In addition, the economic value
of mineral reserves and mineral resources may vary depending on, among other things, metal prices.



34


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




Insurance Risk



The Company’s insurance will not cover all the potential
risks associated with a mining company’s operations. The Company may also be unable to maintain insurance to cover these
risks at economically feasible premiums. Insurance coverage may not continue to be available or may not be adequate to cover any
resulting liability. Moreover, the Company expects that insurance against risks such as environmental pollution or other hazards
as a result of exploration and production may be prohibitively expensive to obtain for a company of Sierra’s size and financial
means. The Company might also become subject to liability for pollution or other hazards which may not be insured against or which
the Company may elect not to insure against because of premium costs or other reasons. Losses from these events may cause the Company
to incur significant costs that could have a material adverse effect upon the Company’s financial condition and results of
operations.



Competitive Risk



The mining industry is competitive in all of its phases.
The Company faces strong competition from other mining companies in connection with the acquisition of properties producing, or
capable of producing, base and precious metals. Many of these companies have greater financial resources, operational experience
and technical capabilities than the Company does. As a result of this competition, the Company may be unable to maintain or acquire
attractive mining properties on terms acceptable to the Company or at all. Consequently, the Company’s revenues, operations
and financial condition could be materially adversely affected.





Sierra’s Common Shares may Experience Price Volatility



Securities of mineral resource and mining companies have
experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the
companies involved. These factors include macroeconomic developments in North America and globally, as well as market perceptions
of the attractiveness of particular industries. The price of the Company’s common shares is also likely to be significantly
affected by short-term changes in commodity prices and currency exchange fluctuation. As a result of any of these factors, the
market price of the Company’s common shares at any given point in time may not accurately reflect the long-term value of
the Company. Securities class-action litigation often has been brought against companies following periods of volatility in the
market price of their securities. The Company may in the future be the target of similar litigation. Securities litigation could
result in substantial costs and damages and divert management’s attention and resources.



Global Financial Risk



Financial markets globally have been subject to increased
volatility. Access to financing has been negatively impacted by liquidity crises throughout the world. These factors may impact
the Company’s ability to obtain loans and other credit facilities in the future and, if obtained, on terms favorable to Sierra.
The levels of volatility and market turmoil are on the rise, and the Company may not be able to secure appropriate debt or equity
financing, any of which could affect the trading price of the Company’s securities in an adverse manner.



35


Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)






Reliance on Key Personnel and Labour Relations



The Company’s operations are dependent on the abilities,
experience and efforts of key personnel. If any of these individuals were to be unable or unwilling to continue to provide their
services to the Company, there may be a material adverse effect on the Company’s operations. The Company’s success
is dependent upon its ability to attract and retain qualified employees and personnel to meet its needs from time to time. The
Company may be negatively impacted by the availability and potential increased costs that may be associated with experienced key
personnel and general labour. Sierra’s ability to achieve its future goals and objectives is dependent, in part, on maintaining
good relations with its employees and minimizing employee turnover. Work stoppages or other industrial relations events at any
of Sierra’s operations could lead to delayed revenues, increased costs and delayed operation cash flows. As a result, prolonged
labor disruptions at any of Sierra’s operations could have a material adverse impact on its operations as a whole.



Coronavirus (COVID-19)

The Company faces risks related to health
epidemics and other outbreaks of communicable diseases, which could significantly disrupt its operations and may materially
and adversely affect its business and financial conditions. The Company’s business could be adversely impacted by the
effects of the coronavirus or other epidemics. In December 2019, a novel strain of the coronavirus emerged in China and the
virus has now spread to several other countries, including Canada, Mexico and Peru, and infections have been reported
globally. The extent to which the coronavirus impacts the Company’s business, including its operations and the market
for its securities, will depend on future developments, which are highly uncertain and cannot be predicted at this time, and
include the duration, severity and scope of the outbreak and the actions taken to contain or treat the coronavirus outbreak.
In particular, the continued spread of the coronavirus globally could materially and adversely impact the Company’s
business including without limitation, employee health, workforce productivity, increased insurance premiums, limitations on
travel, the availability of industry experts and personnel, restrictions to its drill program and/or the timing to process
drill and other metallurgical testing, and other factors that will depend on future developments beyond the Company’s
control, which may have a material and adverse effect on the its business, financial condition and results of operations.
There can be no assurance that the Company’s personnel will not be impacted by these pandemic diseases and ultimately
see its workforce productivity reduced or incur increased medical costs / insurance premiums as a result of these health
risks. In addition, a significant outbreak of coronavirus could result in a widespread global health crisis that could
adversely affect global economies and financial markets resulting in an economic downturn that could have an adverse effect
on the demand for precious metals and our future prospects.

The claims associated with the Company’s Mexican operations
are discussed in detail below:

                                                                                                                                    Minerals, S.A. de C.V. (“P&R”) sued the Company and Dia Bras Mexicana (the “P&R Litigation”).
                                                                                                                                    P&R claimed damages for the cancelation of an option agreement (the “Option Agreement”) regarding the San

                                                                                                                                    In October 2011, the 8th Civil Court of the Judicial District of Morelos in Chihuahua issued a resolution that absolved the
                                                                                                                                    Company from the claims brought against it by P&R on the basis that P&R did not provide evidence to support any of

                                                                                                                                    mineral reserves are located; and (ii) pay $423 to P&R; the Company was not appropriately notified of this resolution. In
                                                                                                                                    February 2013, the Second Federal Collegiate Court on Civil and Labor Matters of the Seventeenth circuit in the State of
                                                                                                                                    Chihuahua (the “Federal Court”) granted the Company a temporary suspension of the adverse resolution issued by
                                                                                                                                    the State Court. In July 2014, the Federal Court ordered that the Company was entitled to receive proper notice of the
                                                                                                                                    adverse resolution previously issued by the State Court. This allows the Company to proceed with its appeal (writ of
                                                                                                                                    “amparo”) of the State Court’s previous resolution. The adverse resolution has been temporarily suspended
                                                                                                                                    since March 2013, which suspension will remain in place pending the writ of amparo. The amparo is being heard in the Federal

                                                                                                                                    non-appealable. On February 12, 2016, the Federal Court issued a new judgment ruling that the
State Court lacked jurisdiction to rule on issues concerning mining titles, and that no previous rulings by the State Court against
the Company shall stand. They ordered the cancellation of the previous adverse resolution by the State Court. On February 6, 2020,
the Company announced the settlement of the P&R Litigation.

| | (b) | In 2009, a personal action was filed
in Mexico against DBM by an individual, Ambrosio Bencomo Muñoz as administrator of the intestate succession of Ambrosio
Bencomo Casavantes y Jesus Jose Bencomo Muñoz, claiming the annulment and revocation of the purchase agreement of two mining
concessions, Bolívar III and IV between Minera Senda de Plata S.A. de C.V. and Ambrosio Bencomo Casavantes, and with this,
the nullity of purchase agreement between DBM and Minera Senda de Plata S.A. de C.V. In June 2011, the Sixth Civil Court of Chihuahua,
Mexico, ruled that the claim was unfounded and dismissed the case, the plaintiff appealed to the State Court. The process is in
the appealing court. The Company will continue to vigorously defend this action and is confident that the claim is of no merit.

The non-IFRS performance measures presented do not have
any standardized meaning prescribed by IFRS and are therefore unlikely to be directly comparable to similar measures presented
by other issuers.

Non-IFRS Reconciliation of Adjusted
EBITDA



EBITDA is a non-IFRS measure that represents an indication
of the Company’s continuing capacity to generate earnings from operations before taking into account management’s financing
decisions and costs of consuming capital assets, which vary according to their vintage, technological currency, and management’s
estimate of their useful life. EBITDA comprises revenue less operating expenses before interest expense (income), property, plant
and equipment amortization and depletion, and income taxes. Adjusted EBITDA has been included in this document. Under IFRS, entities
must reflect in compensation expense the cost of share-based payments. In the Company’s circumstances, share-based payments
involve a significant accrual of amounts that will not be settled in cash but are settled by the issuance of shares in exchange
for cash. As such, the Company has made an entity specific adjustment to EBITDA for these expenses. The Company has also made an
entity-specific adjustment to the foreign currency exchange (gain)/loss. The Company considers cash flow before movements in working
capital to be the IFRS performance measure that is most closely comparable to adjusted EBITDA.



The following table provides a reconciliation of adjusted
EBITDA to the consolidated financial statements for the three months and years ended December 31, 2019 and 2018:

Non-IFRS Reconciliation of Adjusted
Net Income



The Company has included the non-IFRS financial performance
measure of adjusted net income, defined by management as the net income attributable to shareholders shown in the statement of
earnings plus the non-cash depletion charge due to the acquisition of Corona and the corresponding deferred tax recovery and certain
non-recurring or non-cash items such as share-based compensation and foreign currency exchange (gains) losses. The Company believes
that, in addition to conventional measures prepared in accordance with IFRS, certain investors may want to use this information
to evaluate the Company’s performance and ability to generate cash flows. Accordingly, it is intended to provide additional
information and should not be considered in isolation or as a substitute for measures of performance in accordance with IFRS.

Cash Cost per Silver Equivalent Payable
Ounce, Copper Equivalent Payable Pound, and Zinc Equivalent Payable Pound



The Company uses the non-IFRS measure of cash cost per silver
equivalent ounce, copper equivalent payable pound, and zinc equivalent payable pound to manage and evaluate operating performance.
The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information
to evaluate the Company’s performance and ability to generate cash flows. Accordingly, it is intended to provide additional
information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with
IFRS. The Company considers cost of sales per silver equivalent payable ounce, copper equivalent payable pound, and zinc equivalent
payable pound to be the most comparable IFRS measure to cash cost per silver equivalent payable ounce, copper equivalent payable
pound, and zinc equivalent payable pound, and has included calculations of this metric in the reconciliations within the applicable
tables to follow.



All-in Sustaining Cost per Silver Equivalent
Payable Ounce, Copper Equivalent Payable Pound, and Zinc Equivalent Payable Pound



All-In
Sustaining Cost (“AISC”) is a non-IFRS
measure and was calculated based on guidance provided by the World Gold Council (“WGC”) in June 2013. WGC is not a
regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other
mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied,
as well as differences in definitions of sustaining versus development capital expenditures.



AISC is a more comprehensive measure than cash cost per
ounce/pound for the Company’s consolidated operating performance by providing greater visibility, comparability and representation
of the total costs associated with producing silver and copper from its current operations.



The Company defines sustaining capital expenditures as,
“costs incurred to sustain and maintain existing assets at current productive capacity and constant planned levels of
productive output without resulting in an increase in the life of assets, future earnings, or improvements in recovery or grade.
Sustaining capital includes costs required to improve/enhance assets to minimum standards for reliability, environmental or safety
requirements. Sustaining capital expenditures excludes all expenditures at the Company’s new projects and certain expenditures
at current operations which are deemed expansionary in nature.”



Consolidated AISC
includes total production cash costs incurred at the Company’s mining operations, including treatment and refining charges
and selling costs, which forms the basis of the Company’s total cash costs. Additionally, the Company includes sustaining
capital expenditures and corporate general and administrative expenses. AISC by mine does not include certain corporate and non-cash
items such as general and administrative expense and share-based payments. The Company believes that this measure represents the
total sustainable costs of producing silver and copper from current operations and provides the Company and other stakeholders
of the Company with additional information of the Company’s operational performance and ability to generate cash flows. As
the measure seeks to reflect the full cost of silver and copper production from current operations, new project capital and expansionary
capital at current operations are not included. Certain other cash expenditures, including tax payments, dividends and financing
costs are also not included.

Additional Non-IFRS Measures



The Company uses other financial measures, the presentation
of which is not meant to be a substitute for other subtotals or totals presented in accordance with IFRS, but rather should be
evaluated in conjunction with such IFRS measures. The following other financial measures are used:



| | · | Operating cash flows before movements
in working capital - excludes the movement from period-to-period in working capital items including trade and other receivables,
prepaid expenses, deposits, inventories, trade and other payables and the effects of foreign exchange rates on these items.

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)






The terms described above do not have a standardized meaning
prescribed by IFRS, and therefore the Company’s definitions are unlikely to be comparable to similar measures presented by
other companies. The Company’s management believes that their presentation provides useful information to investors because
cash flows generated from operations before changes in working capital excludes the movement in working capital items. This, in
management’s view, provides useful information of the Company’s cash flows from operations and are considered to be
meaningful in evaluating the Company’s past financial performance or its future prospects. The most comparable IFRS measure
is cash flows from operating activities.



| | 13. | related party transactions
| | --- | --------------------------

During the year ended December 31, 2019, the Company recorded
consulting fees of $200 (2018 - $200) to companies related by common directors or officers. At December 31, 2019, accounts payable
and accrued liabilities include $Nil (2018 – $Nil) with these related parties. Related party transactions occurred in the
normal course of business. As at December 31, 2019, the Company has accounts receivable outstanding from these related parties
of $Nil (2018 - $Nil).

| | (b) | Principal Subsidiaries
| | --- | ----------------------



The consolidated financial statements include
the accounts of the Company and its subsidiaries, which are entities controlled by the Company. Control exists when the Company
is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns
through its power over the entity. Subsidiaries are consolidated from the date that control commences until the date that control
ceases.



Non-controlling interests represent equity
interests in subsidiaries owned by outside parties. Changes in the parent company’s ownership interest in subsidiaries that
do not result in a loss of control are accounted for as equity transactions.

| | 14. | CRITICAL ACCOUNTING POLICIES AND ESTIMATES
| | --- | ------------------------------------------





Significant Accounting Judgments and
Estimates



In the application of the Company’s accounting
policies, which are described in note 2 of the Company’s December 31, 2019 consolidated financial statements, management
is required to make judgments, estimates and assumptions about the effects of uncertain future events on the carrying amounts of
assets and liabilities. The estimates and associated assumptions are based on management’s best knowledge of the relevant
facts and circumstances and historical experience. Actual results may differ from these estimates; potentially having a material
future effect on the Company’s consolidated financial statements.



The estimates and underlying assumptions are
reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if
the revision affects only that period, or in the period of the revision and future periods if the revision affects both current
and future periods.



The following are the significant judgments
that management has made in the process of applying the Company’s accounting policies and that have the most significant
effect on the amounts recognized in the consolidated financial statements:



| | (a) | Impairment Review of Asset Carrying Values
| | --- | ------------------------------------------



In accordance with the Company’s
accounting policy, at every reporting period, the Company assesses whether there are any indicators that the carrying value of
its assets or CGUs may be impaired, which is a significant management judgment. Where there is an indication that the carrying
amount of an asset may not be recoverable, the Company prepares a formal estimate of the recoverable amount by analyzing discounted
cash flows. The resulting valuations are particularly sensitive to changes in estimates such as long- term commodity prices, exchange
rates, sales volume, operating costs, and discount rates. In the event of impairment, if there is an adverse change in any of the
assumptions or estimates used in the discounted cash flow model, this could result in a further impairment of the asset. Also,
in accordance with the Company’s accounting policy, the Company capitalizes evaluation expenditures when there is a high
degree of confidence that these costs are recoverable and have a probable future benefit. As at December 31, 2019, management assessed
its mining property assets and exploration and evaluation expenditures for impairment and determined that no impairment was required.

| | (b) | Mineral Reserves and Resources
| | --- | ------------------------------



The Company estimates mineral
reserves and resources based on information prepared by qualified persons as defined in accordance with NI 43-101. These estimates
form the basis of the Company’s life of mine (“LOM”) plans, which are used for a number of important and significant
accounting purposes, including: the calculation of depletion expense and impairment charges, forecasting the timing of the payment
of decommissioning costs and future taxes. There are significant uncertainties inherent in the estimation of mineral reserves and
the assumptions used which include commodity prices, production costs, recovery rates and exchange rates may change significantly
when new information becomes available. Changes in assumptions could result in mineral reserves being revised, which in turn would
impact our depletion expense, asset carrying values and the provision for decommissioning costs.



| | (c) | Deferred Tax Assets and Liabilities
| | --- | -----------------------------------



The Company’s management
makes significant estimates and judgments in determining the Company’s tax expense for the period and the deferred tax assets
and liabilities. Management interprets tax legislation in a variety of jurisdictions and makes estimates of the expected timing
of the reversal of deferred tax assets and liabilities. In addition, management makes estimates related to expectations of future
taxable income based on cash flows from operations and the application of existing tax laws in each jurisdiction. Assumptions used
in the cash flow forecast are based on management’s estimates of future production and sales volume, commodity prices, operating
costs, capital expenditures, dividends, and decommissioning and reclamation expenditures. These estimates are subject to risk and
uncertainty and could result in an adjustment to the deferred tax provision and a corresponding credit or charge to the statement
of loss. The Company is subject to assessments by the various tax authorities who may interpret the tax laws differently. These
differences may impact the final amount or the timing of the payment of taxes. The Company provides for such differences where
known based on management’s best estimates of the probable outcome of these matters.



| | (d) | Decommissioning and Restoration Liabilities Costs
| | --- | -------------------------------------------------



The Company’s provision
for decommissioning and restoration costs is based on management’s best estimate of the present value of the future cash
outflows required to settle the liability. In determining the liability, management makes estimates about the future costs, inflation,
foreign exchange rates, risks associated with the cash flows, and the applicable risk-free interest rates for discounting future
cash flows. Changes in any of these estimates could result in a change in the provision recognized by the Company. Also, the ultimate
costs of environmental disturbance are uncertain and cost estimates can vary in response to many factors including changes to the
relevant legal requirements, the emergence of new restoration techniques or experience at other mine sites.



Changes in decommissioning and
restoration liabilities are recorded with a corresponding change to the carrying amounts of the assets to which they relate. Adjustments
made to the carrying amounts of the asset can result in a change to the depreciation charged in the consolidated statement of loss.

| | (e) | Functional Currency
| | --- | -------------------



The determination of a subsidiary’s
functional currency often requires significant judgment where the primary economic environment in which the subsidiary operates
may not be clear. This can have a significant impact on our consolidated results based on the foreign currency translation methods
described in the audited consolidated financial statements.



| | 15. | OFF BALANCE SHEET ARRANGEMENTS
| | --- | ------------------------------



The Company has no off-balance sheet
arrangements as at December 31, 2019.



| | 16. | DISCLOSURE CONTROLS AND INTERNAL CONTROLS OVER FINANCIAL REPORTING (“ICFR”)
| | --- | ---------------------------------------------------------------------------





Disclosure Controls and Procedures



The Company's management is responsible for designing and
maintaining adequate internal controls over financial reporting and disclosure controls and procedures, under the supervision of
the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of the financial statements in accordance with IFRS.



Management, including the CEO and CFO, has evaluated the
effectiveness of the design and operation of our disclosure controls and procedures as at December 31, 2019, as defined in the
rules of the Canadian Securities Administration. Based on this evaluation, they concluded that our disclosure controls and procedures
are effective in providing reasonable assurance that the information required to be disclosed in reports we filed or submitted
under Canadian securities legislation was recorded, processed, summarized and reported within the time periods specified in those
rules.



Internal Controls Over Financial Reporting



Management, including the CEO and CFO, is responsible for
establishing and maintaining adequate internal control over financial reporting, and used the framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission (COSO) to evaluate the effectiveness of our controls in 2019. Based on this
evaluation, management concluded that our internal control over financial reporting was effective as at December 31, 2019 and provided
a reasonable assurance of the reliability of our financial reporting and preparation of the financial statements.



No matter how well designed any system of internal control
has inherent limitations. Even systems determined to be effective can provide only reasonable assurance of the reliability of financial
statement preparation and presentation.

Changes in Internal Controls Over Financial
Reporting



There have been no changes in ICFR during the three months
ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, ICFR.



| | 17. | CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
| | --- | ----------------------------------------------------



This discussion includes certain statements that may be
deemed “forward-looking”. All statements in this discussion, other than statements of historical fact, addressing future
exploration drilling, exploration and development activities, production activities and events or developments that the Company
expects, are forward looking statements. Although the Company believes the expectations expressed in such forward-looking statements
are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments
may differ materially from those expressed in forward-looking statements. Factors that could cause actual results to differ materially
from those in forward-looking statements include market prices, exploitation and exploration successes, continued availability
of capital and financing, general economic, market or business conditions, and other factors which are discussed under “Risk
Factors” in the Company’s Annual Information Form dated March 27, 2020 available at www.sedar.com and at www.sec.gov
under the Company’s name.



The MD&A contains “forward-looking statements”
within the meaning of the United States Private Securities Litigation Reform Actof 1995 and “forward looking information”
within Canadian securities laws (collectively “forward-looking statements”) related to the Company and its operations,
and in particular, the anticipated developments in the Company’s operations in future periods, the Company’s planned
exploration activities, the adequacy of the Company’s financial resources and other events or conditions that may occur in
the future. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking statements
to the extent that they involve estimates of the mineralization that will be encountered if and when the properties are developed
or further developed. These statements relate to analyses and other information that are based on forecasts of future results,
estimates of amounts not yet determinable and assumptions of management.



These forward-looking statements include, but are
not limited to, relate to, among other things: future production of silver, lead, copper and zinc (the “metals”);
future cash costs per ounce or pound of the metals; the price of the metals; the effects of domestic and foreign laws, regulations
and government policies and actions affecting the Company’s operations or potential future operations; future successful
development of the Yauricocha, Bolivar and Cusi near-mine exploration projects and other exploration and development projects;
the sufficiency of the Company’s current working capital, anticipated operating cash flow or the Company’s ability
to raise necessary funds; estimated production rates for the metals produced by the Company; timing of production; the estimated
cost of sustaining capital; ongoing or future development plans and capital replacement, improvement or remediation programs;
the estimates of expected or anticipated economic returns from the Company’s mining projects; future sales of the metals,
concentrates or other future products produced by the Company; and the Company’s plans and expectations for its properties
and operations.

Risks and uncertainties relating to foreign currency fluctuations;
risks inherent in the mining industry including environmental hazards, industrial accidents, unusual or unexpected geological formations,
ground control problems, flooding and mud rushes; risks associated with the estimation of mineral resources and the geology, grade
and continuity of mineral deposits; the possibility that future exploration, development or mining results will not be consistent
with the Company’s expectations; the potential for and effects of labour disputes or other unanticipated difficulties or
shortages of labour or interruptions in production; actual material mined varying from estimates of grade, tonnage, dilution and
metallurgical and other characteristics; the inherent uncertainty of pilot-mining activities and cost estimates, including the
potential for unexpected costs/expenses and commodity price fluctuations; uncertain political and economic environments; changes
in laws or policies, foreign taxation, delays or the inability to obtain necessary governmental permits.



Any statements that express or involve discussions
with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance
(often, but not always, using words or phrases such as “expects”, “anticipates”, “plans”,
 “projects”, “estimates”, “assumes”, “intends”, “strategy”, “goals”,
 “objectives”, “potential” or variations thereof, or stating that certain actions, events or results “may”,

Sierra Metals Inc. Management’s Discussion and Analysis For the year ended December 31, 2019 (In thousands of United States dollars, unless otherwise stated)




This list is not exhaustive of the factors that may affect
any of the Company’s forward-looking statements. Forward looking statements are statements about the future and are inherently
uncertain, and the Company’s actual achievements or other future events or conditions may differ materially from those reflected
in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those
referred to in this MD&A under the heading ‘‘Other Risks and Uncertainties”. The Company’s forward-looking
statements are based on the beliefs, expectations and opinions of management on the date the statements are made, and the Company
does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs, expectations
or opinions should change, other than as required by applicable law. For the reasons set forth above, one should not place undue
reliance on forward-looking statements.





Cautionary Note to U.S. Investors Concerning
Estimates of Inferred Resources



This document uses the term “Inferred Mineral Resources”.
U.S. investors are advised that while this term is recognized and required by Canadian regulations, the Securities and Exchange
Commission (“SEC”) does not recognize it. Inferred Mineral Resources have a great amount of uncertainty as to their
existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred
Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may
not form the basis of economic studies other than a Preliminary Economic Assessment (PEA).



This document also uses the terms “Measured and Indicated
Mineral Resources”. The Company advises U.S. investors that while these terms are recognized by Canadian regulations, the
SEC does not recognize them. U.S. investors are cautioned not to assume that any part or all of mineral deposits included in these
categories will ever be converted into mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated
economic viability. Disclosure of “contained ounces” is permitted under Canadian regulations; however, the SEC normally
only permits the reporting of non-reserve mineralization as in-place tonnage and grade.
