## Exhibit 99.1

**EXHIBIT 99.1**

**Aura Reports Updated Mineral Reserves and Mineral Resources For The Year-Ended 2025, Highlighting year of Significant Growth in Mineral Reserve and Resource Portfolio**

ROAD TOWN, British Virgin Islands, April 01, 2026 (GLOBE NEWSWIRE) -- **Aura Minerals Inc. (NASDAQ: AUGO) (B3: AURA33)** ("**Aura**" or the "**Company**") is pleased to report updated Mineral Reserves and Mineral Resources ("**MRMR**") for its six operating mines: Aranzazu Mine, Apoena Mines, Minosa Mine, Almas Mine, Borborema Mine and MSG Mine, as well as its development projects including Era Dorada and Matupá. Between 2024 and 2025, Aura updated its MRMR models to reflect new data. Updates were driven by exploration drilling, revised geological interpretations, changes in mining methods, extraction plans, and economic parameters, including commodity prices that impacted cut-off grades and reserve classification, as well as M&A activities. The Company is also pleased to report that it has filed its annual report on Form 20-F for the fiscal year ended December 31, 2025 (the "2025 Annual Report") with the Securities and Exchange Commission (the "SEC"). The 2025 Annual Report can be accessed by visiting either the SEC's website at www.sec.gov or the Regulatory Filings section of the Company's investor relations website at https://www.auraminerals.com/en/investors/. Aura`s 2025 Annual Report included new S-K 1300 technical report summaries for Borborema, Almas, Matupá and Mineração Serra Grande as exhibits.

Rodrigo Barbosa, President and CEO of Aura commented, "2025 marked another year of disciplined execution and significant portfolio acceleration for Aura. We invested US$21.8 million in exploration, drilling over 106,500 meters while maintaining one of the industry's lowest discovery costs. The results have truly exceeded expectations. Our P&P reserves grew substantially from 3.4 million to 7.22 million GEO, driven not only by the successful acquisition of the MSG Project and new reserves at Era Dorada, but also by strong organic growth. This includes the robust update at Borborema, where we achieved meaningful reserve additions through higher gold prices, pit expansion and improved geological models — independent of the road relocation — as well as the successful addition of underground reserves at Almas' Paiol deposit. This growth significantly strengthens our production foundation for years to come. M&I resources increased 26% to approximately 3.49 million GEO, while Inferred Resources more than tripled (+200%), reaching 3.92 million GEO — boosted by the inclusion of MSG along with positive conversions and expansions at Borborema and Almas.

In all, we continue to walk the talk on our strategy: **(i) production growth:** in 2025 we produced 280k GEO and we expect to achieve over 600k GEO in the upcoming years; **(ii) Resources and Reserves growth**: we have increased to 7.2 million GEO, **(iii) additional growth and daily traded volume**: in 2025 we closed two acquisitions (MSG and Era Dorada) while we increased our ADTV from US$2 million in early 2025 to over US$90 million during the first three months of 2026. We are building a stronger, more diversified, and longer-life portfolio that positions Aura for sustainable growth and superior returns in the years ahead".

**Highlights:**

* In 2025, Aura executed 106,941m of drilling with a total exploration spend, inclusive of capex, of US$21.8
million, maintaining a low global discovery cost. The Company's strategy balanced near-term mine life extension with a strong focus
on long-term growth, advancing greenfield and brownfield targets while leveraging strategic M&A to expand its future resource base.

* **Consolidated Proven & Probable ("P&P")** Mineral Reserves were significantly
increased and totaled 7,223k GEO, primarily driven by: (i) the inclusion of the MSG Project in Aura's MRMR portfolio after acquisition;
(ii) Borborema Mineral Reserve update, due to the approval for the road relocation, and (iii) increase in P&P due to results of exploration
works performed in 2025, price cut-off increase and review of models, particularly at Borborema. Also, the P&P increased due to the
addition of Mineral Reserves at Era Dorada. 

**Metal price assumptions used for estimating Mineral Reserves were updated to reflect a significantly higher pricing environment while maintaining a conservative outlook:** gold at US$2,600/oz (up from US$2,000), copper at US$4.40/lb
(up from US$4.20), and silver at US$35.00/oz (up from US$25.00). 

![](fig1.jpg)

* **Exclusive Measured & Indicated (M&I)-** Mineral Resources decreased 52% to 3,173k
GEO, driven mainly by conversion to Mineral Reserve in Borborema and Era Dorada and conversion of M&I Mineral Resources at depth in
Paiol to Mineral Reserves (2P).

![](fig2.jpg)

* **Inferred Mineral Resources** increased by more than 200% to 3,917k GEO, primarily driven
by inclusion of the MSG Project; Borborema Mineral Reserve update and incorporation of Almas underground Mineral Reserve.

**Strong Ongoing Exploration Growth Trajectory:** 

**Pé Quente and Pezão** (Matupá Project): In 2024, Aura acquired the exploration rights over the Pé Quente Project, located in the State of Mato Grosso, Brazil, near the Matupá Project. Following positive exploration results, Aura exercised the purchase option in 2025, definitively acquiring the project for a total consideration of US$4.5 million, payable in installments between 2025 and 2028.Exploration activities in 2025 focused on detailed infill and extension drilling, with 57 drill holes totaling 9,978.16 m completed. The program confirmed the continuity of gold mineralization, expanded the mineralized footprint, and improved geological confidence across key zones. As a result of drilling campaigns conducted in 2024 and 2025, Pé Quente hosts approximately 287 koz Au of Indicated and Inferred Mineral Resources, representing a material addition to the Matupá Project's resource base. Aura has to filed a new S-K 1300 technical report summary with respect to the Matupá Gold Project, including an initial assessment of Pé Quente, as an exhibit to our 2025 Annual Report.

**Almas Mine** (Paiol Deposit): https://api.mziq.com/mzfilemanager/v2/d/7e088be0-b725-4cba-ab5e-4969a4ac92af/0f718b0a-6c06-6d6d-6ef9-7a8ce1dea720?origin=1In 2025, Aura advanced an intensive infill drilling program at the Paiol Underground, completing 32 diamond drill holes totaling 11,435.40 m, complemented by 8 directional drill holes totaling 3,109.80 m. The drilling confirmed the continuity of high-grade underground mineralization below the current open pit, supporting the development of a scalable underground operation. Key intercepts include 60.25 m @ 0.97 g/t Au (PAI-021-D1B) and 50.90 m @ 0.89 g/t Au (PAI-020-D2), defining broad mineralized envelopes suitable for bulk underground mining. These intervals host higher-grade internal zones, such as 4.50 m @ 5.37 g/t Au and 3.15 m @ 4.85 g/t Au, confirming the presence of high-grade shoots within the broader system. The infill program resulted in the addition of underground Mineral Resources and Mineral Reserves, and the mineralized bodies remain open at depth, with additional drilling planned for 2026. Beyond Paiol UG, Aura views the Almas district as a high-potential gold camp and continues, in parallel, to advance earlier-stage regional targets within the broader Almas area. These targets represent future optionality, with the potential to contribute additional Mineral Resources to the MRMR over the coming years. Aura has filed a new S-K 1300 technical report summary with respect to Almas as an exhibit to our 2025 Annual Report.

**Carajás:** During 2023 and 2024, Aura completed over 21,000 m of drilling, confirming continuous mineralization along a 7 km strike, delineating three key zones (Trend S, Trend SW, Trend N – Regional). The results highlight the target's strong potential. Assay results indicate copper grades ranging from 0.2% Cu to 0.5% Cu over thicknesses of approximately 50 m, mainly associated with disseminated sulphides in hydrothermally altered rocks. Within these broader zones, higher-grade copper intervals (>0.5% Cu) with typical thicknesses of 15 to 20 m, as well as semi-massive sulphide zones exceeding 1.0% Cu with average thicknesses of approximately 5 m (not true width), were identified. In 2025, Aura continued exploration activities to further evaluate the potential of the target, completing an additional 11,000 m of drilling aimed at improving geological understanding and data reliability. Exploration activities remain ongoing, and complementary geophysical surveys are planned for 2026 to refine target definition and support future exploration planning. The Company continues to view the project as a prospective copper system with potential for advancement through successive stages of evaluation.

**Aranzazu, Mexico**

Infill and deep drilling conducted between 2018 and 2025 in the Glory Hole (GH) zone successfully extended known mineralization and, in 2025, completed the conversion of the final level of the GHFW (Glory Hole Footwall) into the Mineral Resource and Reserve inventory. While lateral continuity within the GH zone is limited, the system remains open at depth with economic grades and mineable thicknesses (GHHW). Following the completion of the GHFW conversion, exploration efforts from 2026 onward will focus on the conversion of the GHHW (Glory Hole Hangingwall) and on new mineralized zones, including Esperança, where drilling in 2025 returned promising copper and gold results.

P&P Mineral Reserves increased by increased by 1.59 Mt (+14%), while metal content decreased by 57,077 GEO (-7%) and NSR declined by 9%, reflecting updates to the resource model. After depletion, total tonnes increased by 18%. A change in NSR cut-off compared to 2024 (+10%) was due to the update of the actual operating costs reviewed during the 2025 period; however, this compensated by a 10% increase in the NSR factors, driven by improved metal prices and recoveries aligned with the reserve grades.

M&I Mineral Resources decreased by 10% after depletion due to excluding areas that were no longer accessible in the mine and changing in prices and NSR formula.

Inferred Mineral Resources decreased by 7% in metal content, mainly due to conversion to M&I.

The Qualified Person for all changes since the date of last S-K 1300 technical report summary for this mine is Farshid Ghazanfari, P.Geo., Geology and Mineral Resources Manager for the Company.

**The charts below show changes in P&P Mineral Reserves, M&I Mineral Resources (Exclusive) and Inferred Mineral Resources for the Aranzazu Mine as of December 31, 2025, compared to July 7, 2025**

![](fig4.jpg)

**Apoena, Brazil**

The 2025 exploration campaign at Apoena was focused on the Nosde–Lavrinha corridor, with emphasis on the Lower Trap zone, which hosts the same style of mineralization historically mined at the Ernesto Mine. During the year, Aura completed approximately 11 km of drilling, targeting this zone to better assess its geological continuity and mineral potential. Partial results from the drilling program indicate the occurrence of mineralization within the Lower Trap, supporting the interpretation of a continuous mineralized system between Nosde and Lavrinha. Complete assay results are expected in Q1 2026, when Aura will be able to conduct a more comprehensive evaluation of the potential of this zone and define next exploration steps.

P&P Mineral Reserves decreased by 6% in metal content, despite higher gold prices, primarily due to depletion.

M&I Mineral Resources increased slightly by 33% in tonnes and 11% in metal content (after depletion) due to higher gold prices and lower cut-off. The grade decreased by 6%.

Notably, Inferred Mineral Resources increased by 10% in metal content, mainly at Nosde-Lavrinha and Ernesto Connection, supported by infill and exploration drilling.

The Qualified Person for all changes since the date of last S-K 1300 technical report summary for this mine is Farshid Ghazanfari, P.Geo., Geology and Mineral Resources Manager for the Company..

![](fig5.jpg)

**Minosa (San Andres), Honduras**

Proven and Probable (P&P) Mineral Reserves increased by 5% in tonnes and decreased by 8% in gold content as result of depletion from production in 2025 and change of model. Contributing factors also included, a larger and deeper designed pit due to change of gold price and a lower cut-off grade.

M&I Mineral Resources decreased by 9% due to conversion to Mineral Reserve and Inferred Resources decreased by 10% due to conversion M&I Mineral Reosurces. The Qualified Person for all changes since the date of last S-K 1300 technical report summary for this mine is Farshid Ghazanfari, P.Geo., Geology and Mineral Resources Manager for the Company.

**Almas, Brazil**

Late 2024 and early 2025, Aura commenced a deep drilling program(directional drilling) aiming to establish mineral resources and reserve the open pit below in the Paiol mine for an underground operation. Due to changing mining methods, Aura hired SLR consultants to update the technical report with the inclusion of underground mining operations and updated metal prices.

The updated technical report integrated open pit and underground life of mine (LOM) plan in Paiol after a successful drilling campaign. The LOM increased to 12 years with transition between mining areas which is supported by sequencing, geotechnical design parameters, and operational considerations.

The Almas Operation consists of three open pit mines (Paiol, Vira Saia, Cata Funda), and one underground mine (Paiol) currently under development. At present, the Paiol open pit is the sole ore source. Underground development at Paiol began in 2025, with initial underground production planned for 2028. Mining at the Vira Saia open pit is planned for 2027, followed by Cata Funda in 2030. Existing heap-leach reserves and low-grade stockpiles are also incorporated into the LOM plan.

Open pit operations will use conventional truck-and-shovel mining with 4.5 cubic metre (m³) excavators, front-end loaders, and 70-t haul trucks. The final pit designs were based on optimization studies, supporting a planned run-of-min (ROM) production rate of 3.0 Mtpa and approximately 141 Mt of waste over an eight-year open pit mining period.

The underground mine will be developed primarily using transverse sublevel stoping, with localized longitudinal stopes. Primary stopes will be filled with cemented rockfill, and secondary stopes with rockfill.

Ore feed will transition from the Paiol open pit to a combination of Vira Saia, Cata Funda, and underground production, before shifting entirely to stockpiles from 2033 to 2037, resulting in a 12-year processing period.

Across all deposits, the operation will mine 29.5 Mt of ore at 0.86 g/t Au, supplemented by 4.3 Mt of stockpiled ore averaging 0.55 g/t Au. Processing throughput will begin at 2 Mtpa in 2026, increasing to 3 Mtpa from 2027 onward.

By December 31, 2025, Proven and Probable Mineral Reserves (open pit) are estimated to total 24,723 thousand tonnes (kt), averaging 0.80 g/t Au and containing 634 kt Au and Probable Mineral Reserves (Paiol Underground) are estimated to total 4,817 kt, averaging 1.16 g/t Au and containing 180 thousand ounces (koz) Au.

By December 31, 2025, Proven Mineral Reserves (Stockpile) are estimated to total 4,338 kt, averaging 0.55 g/t Au and containing 77 thousand ounces (koz) Au.

Proven and Probable (P&P) Mineral Reserves increased 70% in tonnes (after depletion); despite a 19% grade reduction from lower cut-off, metal content rose 32% driven by open pit and UG integration (Paiol UG Mineral Reserves**:** 4.82 Mt @ 1.16 g/t Au, totaling 180 Koz).

By December 31, 2025, Open pit Measured and Indicated (M&I) Mineral Resources(exclusive) are estimated to total 4,323 thousand tonnes (kt) averaging 0.47 g/t Au and containing 65 kt Au and underground Indicated Mineral Resources are estimated to total 2,227 kt averaging 0.88 g/t Au and containing 63 koz Au.

M&I Mineral Resources decreased by 46% in tonnes and 54% by metal content (after depletion), due to the conversion to UG mineral reserves in Paiol, in Cata Funda and Vira Saia, and the change of models.By December 31, 2025, open pit Inferred Mineral Resources are estimated to total 3,071 kt averaging 0.76 g/t Au and containing 75 koz Au and underground Inferred Mineral Resources are estimated to total 3,744 kt averaging 0.67 g/t Au and containing 81 koz Au.

Similarly, Inferred Mineral Resources increased 93%, partially converted to M&I at Paiol and Cata Funda. At Paiol, Inferred Resources increased by 37% in metal content, driven by deeper drilling and the inclusion of UG resources not reported in 2024. At Vira Saia, Inferred Resources increased by more than 100%, supported by higher gold prices, lower cut-off, and a larger pit shell.

For more information, refer to the S-K 1300 technical report summary filed as an exhibit to our 2025 Annual Report.

![](fig7.jpg)

**Borborema, Brazil**

An updated Feasibility Study completed in March 2026, using a higher gold price and considering the relocation of the highway, outlined an anticipated average annual gold production of 57 koz, with an estimated LOM of 35 years. The technical report summary was filed as an exhibit to our 2025 Annual Report.

The paved highway (BR 226) to the south and the high voltage transmission line (HVTL) to the north—previously identified in the prior Technical Report (F-1 filing) as limiting infrastructure—no longer impose constraints on the pit design (see Aura press release February 26, 2026)

Aura owns the surface rights in the constrained pit area, which considers the current road design, and previous infrastructures, including the processing plant, which hasn't changed in this report. Aura has already started the operation considering the constrained pit.

The Life of Mine (LOM) schedule extends for approximately thirty-five years and four months. Key scheduling parameters include a nominal plant throughput of 2.0 Mt per year and adherence to Aura's existing mine plan during the initial two years of operation. The processing facility is limited to a maximum of 10% oxidized material in the feed blend. A low-grade stockpiling strategy is incorporated to increase the head grade during the early phases of the operation.

Mineral Reserves are defined within detailed engineered pit designs and life-of-mine (LOM) plans that are based on optimized pit shells. Mineral Reserves within these engineered pit designs were calculated using cut-off grades (COG) specific to each rock type, considering a gold price of US$2,600/oz with an exchange rate of R$5.5/US$1.0. Mineral Reserves include 3.2 Mt of stockpiled material. Mineral Reserves that have an effective date of December 31st, 2025, are estimated to be 70.6 Mt at 0.88 g/t Au grade.

Proven and Probable (P&P) Mineral Reserves increased significant in tonnes and metal content, with +170% in metal content vs. 2024, driven by highway relocation, gold price cutoff increase and expansion of the Mineral Reserve pit.

M&I Mineral Resources increased by 40% in tonnes and 16% in metal content (before depletion), supported by higher metal prices and lower cut-off grade.

Inferred Resources increased by 79% in metal content, driven by a larger pit shell and lower cut-off grade

![](fig8.jpg)

**Era Dorada, Brazil**

A new Feasibility Study completed in December 2025 by Ausenco outlined anticipated production of 1600 tonnes per day(t/d) The planned Life of Mine (LoM) extends for approximately 17 years (Average production of approximately 111koz GEO for the first 4 years)., with higher metal output scheduled in the early years through prioritized access to higher-grade areas. (see Aura's press release December 8, 2025 for more details). The technical report summary was incorporated by reference as an exhibit to our 2025 Annual Report.

Era Dorada has Proven and Probable Mineral Reserves of 1.7 million ounces gold, assuming 8.75 million tonnes at 6.01 grams per tonne gold.

Proven and Probable (P&P) Mineral Reserves kept stable when compared with the F1 2025 report. Although comparing with 2024, the new underground (UG) Mineral Reserve totaling 1.8 Moz Au was established for the Era Dorada Project, supported by a Feasibility Study completed released in December 2025, using a long-term gold price of US$2,000/oz.

Era Dorada has Exclusive Indicated Mineral Resources of 503 Koz gold, assuming 2.46 million tonnes at 6.36 grams per tonne gold.

M&I Mineral Resources Increased by 7% in metal content, driven by a higher gold price assumption (US$2,500/oz) applied in the Feasibility Study.

Inferred Resources increased by 21% in metal content, also reflecting the higher gold price (US$2,500/oz) compared to the initial Assessment report in 2025 (F1 Report).

**Matupá, Brazil**

Since the completion of the Feasibility Study in 2022, Aura has continued to advance regional exploration at Matupá, with the goal of identifying and developing satellite deposits to support long-term growth. Exploration and extension drilling programs have been a key focus, targeting numerous gold occurrences and anomalies within a 50km radius of the X1 deposit.The exploration efforts and drilling first were focused on Serrinhas target within Aura's concession. Later, Aura acquired the Pe Quente project, drilled significant intercepts and validate historical results during 2024 and 2025. The results of Pe Quente and Serrinhas drilling established Mineral Resource inventories for these two deposits and lead to an amendment to the existing Matupa Technical Report which released in March 2026 and was filed as an exhibit to our 2025 Annual Report.

At the Pé Quente the total drilling database includes 163 core holes and 39 air-core holes drilled between 2010 and the effective date of the technical report. The current core drilling database comprises 29,806.70 m.

At the Serrinhas target, drilling campaigns totalize approximately 45,348 m, distributed across 228 holes, including 212 DDH and 16 RC holes, drilled between 1996 and 2024. Pé Quente target has Indicated Mineral Resources of 124 Koz gold, assuming 5.68 million tonnes at 0.68 grams per tonne gold and Inferred Mineral Resources of 163 Koz gold, assuming 6.62 million tonnes at 0.77 grams per tonne gold.

Serrinhas target has Indicated Mineral Resources of 84 Koz gold, assuming 2.60 million tonnes at 1.01 grams per tonne gold and Inferred Mineral Resources of 118 Koz gold, assuming 4.61 million tonnes at 0.79 grams per tonne gold

Matupa Project Proven and Probable (P&P) Mineral Reserves kept stable when compared to the previous report as there was no mineral reserve established for Serrinhas and Pé Quente.

Matupa Project M&I Mineral Resources increased 89%, due to the inclusion of Serrinhas and Pé Quente.

No drilling was conducted in X1 in 2025. The inferred resources are limited at depth due to faulting, and further drilling will not increase them.

**The charts below show changes in P&P Mineral Reserves Estimates, M&I Mineral Resources Estimates and Inferred Mineral Resources Estimates for Matupá as of December 31, 2025, compared to December 31, 2024**.

**Caution Regarding Forward-Looking Information and Statements**

All statements other than statements of historical fact are forward-looking statements. Forward-looking statements relate to future events or future performance and reflect the Company's current estimates, predictions, expectations or beliefs regarding future events and include, without limitation, statements with respect to: expected production from, and the further potential of the Company's properties; the ability of the Company to achieve its longer-term outlook and the anticipated timing and results thereof; the ability to lower costs and increase production; the economic viability of a project; strategic plans, including the Company's plans with respect to its properties; amounts of mineral reserves and mineral resources; the amount of future production over any period; capital expenditure and mine production costs; the outcome of mine permitting and other required permitting; the outcome of legal proceedings which involve the Company; information with respect to the future price of copper, gold, silver and other minerals; estimated mineral reserves and mineral resources; the Company's exploration and development program; estimated future expenses; exploration and development capital requirements; operating costs; strip ratios and mining rates; expected grades and ounces of metals and minerals; expected processing recoveries; expected time frames; prices of metals and minerals; mine life; the ability of the Company to successfully maintain operations at its producing assets, or to restart these operations efficiently or economically, or at all; timing of anticipated technical reports on the properties; and the ability of the Company to continue as a going concern. Often, but not always, forward-looking statements may be identified by the use of words such as "expects", "anticipates", "plans", "projects", "estimates", "assumes", "intends", "strategy", "goals", "objectives" or variations thereof or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, or the negative of any of these terms and similar expressions.

Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Company, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Forward-looking statements in the 2025 Annual Report are based upon, without limitation, the following estimates and assumptions: the presence of and continuity of metals at the Company's projects at modeled grades; the capacities of various machinery and equipment; the availability of personnel, machinery and equipment at estimated prices; exchange rates; metals and minerals sales prices; appropriate discount rates; tax rates and royalty rates applicable to the mining operations; cash costs; anticipated mining losses and dilution; metals recovery rates, reasonable contingency requirements; our expected ability to develop adequate infrastructure at a reasonable cost; our expected ability to develop our projects including financing such projects; and receipt of regulatory approvals on acceptable terms.

Known and unknown risks, uncertainties and other factors, many of which are beyond the Company's ability to predict or control could cause actual results to differ materially from those contained in the forward-looking statements. Specific reference is made to the section entitled "Risk Factors" in our 2025 Annual Report, for a discussion of some of the factors underlying forward-looking statements, which include, without limitation, risks related to exploration, development and operations, market fluctuations and commercial quantities of minerals, funding needs, liquidity and going concerns, foreign operations, government regulations, consents and approvals, stakeholders, increases in production costs, construction and development of new mines, infrastructure, concentration of customers, environmental and safety regulations and risks, competition, retention of key personnel, uncertainty in the estimation of mineral resources and reserves, replacement of depleted mineral reserves, production estimates, currency risk, write-downs and impairments, mineral titles, market price of Shares and Brazilian Depositary Receipts ("BDRs"), insurance and uninsured risks, public company obligations, tax matters, information technology, labour and employment matters, nature and climatic conditions, risks inherent in acquisitions, reputational risk, risks associated with transportation and storage of ingots or concentrate, risks associated with joint ventures, illegal activity, litigation, enforcement of judgments, interests of the controlling shareholder, dividend policy and global financial conditions. Readers are cautioned that the foregoing list of factors is not exhaustive of the factors that may affect the forward-looking statements.

All forward-looking statements herein are qualified by this cautionary statement. Accordingly, readers should not place undue reliance on forward-looking statements. The Company undertakes no obligation to update publicly or otherwise revise any forward-looking statements whether as a result of new information or future events or otherwise, except as may be required by law. If the Company does update one or more forward-looking statements, no inference should be drawn that it will make additional updates with respect to those or other forward-looking statements.

**Caution Regarding Mineral Resource and Mineral Reserve Estimates**

The figures for mineral resources and reserves contained herein are estimates only and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that the mineral resources and reserves could be mined or processed profitably. Actual reserves, if any, may not conform to geological, metallurgical or other expectations, and the volume and grade of ore recovered may be below the estimated levels. There are numerous uncertainties inherent in estimating mineral resources and reserves, including many factors beyond the Company's control. Such estimation is a subjective process, and the accuracy of any reserve or resource estimate is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation. Short-term operating factors relating to the mineral resources and reserves, such as the need for orderly development of the ore bodies or the processing of new or different ore grades, may cause the mining operation to be unprofitable in any particular accounting period. In addition, there can be no assurance that metal recoveries in small scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. Lower market prices, increased production costs, the presence of deleterious elements, reduced recovery rates and other factors may result in revision of its resource and reserve estimates from time to time or may render the Company's resources and reserves uneconomic to exploit. Resource and reserve data is not indicative of future results of operations. If the Company's actual mineral resources and reserves are less than current estimates or if the Company fails to develop its resource base through the realization of identified mineralized potential, its results of operations or financial condition may be materially and adversely affected.

All forward-looking statements herein are qualified by this cautionary statement. Accordingly, readers should not place undue reliance on forward-looking statements. The Company undertakes no obligation to update publicly or otherwise revise any forward-looking statements whether as a result of new information or future events or otherwise, except as may be required by law. If the Company does update one or more forward-looking statements, no inference should be drawn that it will make additional updates with respect to those or other forward-looking statements.
