                   Homestake Mining Company and Subsidiaries


Notes to Condensed Consolidated Financial Statements (unaudited)
----------------------------------------------------------------


1.  General Information

    The condensed consolidated financial statements include Homestake Mining
    Company and its majority-owned subsidiaries, and their undivided interests
    in joint ventures (collectively, "Homestake" or the "Company") after
    elimination of intercompany amounts.

    The information furnished in this report reflects all normal recurring
    adjustments which, in the opinion of management, are necessary for a fair
    statement of the results for the interim periods. Results of operations for
    interim periods are not necessarily indicative of results for the full year.
    These unaudited condensed consolidated financial statements should be read
    in conjunction with the financial statements and notes thereto, which
    include information as to significant accounting policies, in the Company's
    Annual Report on Form 10-K for the year ended December 31, 1999.

    All dollar amounts are in United States dollars unless otherwise indicated.

    In June 1998, the Financial Accounting Standards Board ("FASB") issued
    Statement of Financial Accounting Standards No. 133 ("SFAS 133"),
    "Accounting for Derivative Instruments and Hedging Activities." SFAS 133
    requires that derivatives be recognized as assets or liabilities and be
    measured at fair value. Gains or losses resulting from changes in the value
    of derivatives are to be accounted for depending on the use of the
    derivatives and whether they qualify for hedge accounting as either a fair
    value hedge or a cash flow hedge. The key criterion for hedge accounting is
    that the hedging relationship must be highly effective in achieving
    offsetting changes in fair value or cash flows of the hedging instruments
    and the hedged items. SFAS 133 is effective for fiscal years beginning after
    June 15, 2000. In June 2000, the FASB issued SFAS 138, "Accounting for
    Certain Derivative Instruments and Certain Hedging Activities, an amendment
    of SFAS 133" ("SFAS 138"). Under the amended standard, certain components of
    the Company's precious metals hedging program may be excluded from the
    accounting requirements of SFAS 133 provided they meet certain criteria to
    qualify as a normal purchase and sale transaction. The Company has not
    determined whether its precious metals hedging contracts will meet the
    criteria for exclusion. The Company believes that changes in unrealized
    gains and losses on Homestake's derivative activities, to the extent subject
    to the requirements of SFAS 133 and SFAS 138, will qualify for hedge
    accounting and, to the extent effective, be deferred in other comprehensive
    income. However, there are many complexities to SFAS 133 and SFAS 138, and
    the Company currently is evaluating their impact on reported operating
    results and financial position. The effects of adopting the new standard are
    not reasonably determinable at this time. The Company expects to adopt SFAS
    133 and SFAS 138 effective January 1, 2001.

    In December 1999, the Securities and Exchange Commission (SEC) issued Staff
    Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
    Statements" which outlines the basic criteria required to recognize revenue,
    and provides guidance on the presentation and disclosure of revenue in
    financial statements filed with the SEC. SAB 101 is required to be
    implemented no later than the fourth quarter of 2000. The Company is
    awaiting additional implementation guidance, which is expected to be issued
    shortly by the SEC, in order to evaluate the effect, if any, that this
    bulletin may have on the consolidated financial statements.

2.  Acquisition - Argentina Gold Corp.

    In April 1999, Homestake issued 20.9 million common shares to acquire
    Argentina Gold Corp. ("Argentina Gold"), a publicly-traded Canadian gold
    exploration company whose principal asset is its 60% interest in the
    Veladero property located in northwest Argentina. The business combination
    was accounted for as a pooling of interests, and accordingly, Homestake's
    consolidated financial statements include Argentina Gold for all periods
    presented. The Company recorded business combination expenses of $3.5
    million and $4.8 million in the three and six month periods ended June 30,
    1999, respectively, related to this transaction.

4.  Write-downs and Other Unusual Charges

    During the second quarter of 1999, the Company determined that further
    participation in an exploration joint venture in Eastern Europe was
    unwarranted. As a result, Homestake recorded a write-down of $3.5 million
    related to the carrying value of this investment.

5.  Discontinued Operations

    The Company has a 16.7% undivided joint-venture interest in the Main Pass
    299 sulfur mine in the Gulf of Mexico. In July 2000, in view of continued
    low sulfur prices and increased operating costs, Freeport-McMoRan Sulphur
    LLC, the operator and 83.3% owner of the Main Pass sulfur mine, announced a
    phased closure of sulfur operations. Sulfur production is anticipated to
    phase out over a six to nine month period. The Company's joint venture
    interest was reflected as a discontinued operation at June 30, 2000. The
    Company wrote off the carrying value of sulfur property, plant and equipment
    amounts in 1997. Results for the three and six months ended June 30, 2000
    include provisions of $3.5 million for estimated operating losses during the
    closure period and $8.5 million for estimated remaining unaccrued mine
    reclamation and closure costs.

  Gold and Silver Contracts

  Homestake's hedging policy provides for the use of forward sales contracts to
  hedge up to 30% of each of the following ten year's expected annual gold
  production, and up to 30% of each of the following five year's expected annual
  silver production, at prices in excess of certain targeted prices.  The policy
  also provides for the use of combinations of put and call option contracts to
  establish minimum floor prices.

  In March 2000, the Company closed out and financially settled its remaining US
  dollar denominated silver forward sales contracts covering 3.6 million ounces
  maturing in 2000 and 2001.  The pretax gain of $3.3 million was deferred and
  is being recorded in income as the originally designated production is sold.
  At June 30, 2000, the unamortized portion of this gain was $2.4 million, of
  which $0.4 million was classified as noncurrent.  The noncurrent deferred gain
  on close-out of forward sales contracts at June 30, 2000 also includes $28.5
  million related to the 1999 close-out of gold forward sales contracts maturing
  in the years 2001, 2002 and 2003.  An additional $6.5 million of deferred
  gains on this transaction is classified as current and is included in accrued
  liabilities in the accompanying balance sheet at June 30, 2000.

10.  Segment Information

     The Company primarily is engaged in gold mining and related activities.
     Gold operations are managed and internally reported based on the following
     geographic areas: North America (United States and Canada), Australia and
     South America. The Company also has other foreign exploration activities
     and an oil recovery operation in the Gulf of Mexico, which are included in
     "Corporate and All Other". Within each geographic segment, operations are
     managed on a mine-by-mine basis. However, because each mine has similar
     characteristics, the Company has geographically aggregated its operations.
     As discussed in note 5, the Company's results from its sulfur operations
     are reflected as a discontinued operation, and therefore, have been
     excluded from the segment information.

11. Contingencies

    Environmental Contingencies

    The Comprehensive Environmental Response, Compensation and Liability Act of
    1980 imposes heavy liabilities on any person who discharges hazardous
    substances.  The Environmental Protection Agency publishes a National
    Priorities List ("NPL") of known or threatened releases of such substances.

    Homestake's former uranium millsite near Grants, New Mexico is listed on the
    NPL. Pursuant to the Energy Policy Act of 1992, the United States Department
    of Energy ("DOE") is responsible for 51.2% of past and future costs of
    reclaiming the Grants site in accordance with Nuclear Regulatory Commission
    license requirements. Through June 30, 2000, Homestake had received $29.3
    million from the DOE and the balance sheet at June 30, 2000 includes an
    additional receivable of $6.0 million for the DOE's share of reclamation
    expenditures made by Homestake through 1999.

    In 1983, the State of New Mexico filed claims against Homestake for natural
    resource damages resulting from the Grants site. To date, the State has
    taken no action to enforce its claims.

    Other Contingencies

    In addition to the above, the Company is party to legal actions and
    administrative proceedings and is subject to claims arising in the ordinary
    course of business. The Company believes the disposition of these matters
    will not have a material adverse effect on its financial position or results
    of operations.

12. Homestake Canada Inc. ("HCI")

    In connection with the 1998 acquisition of the minority interests in Prime
    Resources Group Inc., HCI issued 11.1 million HCI exchangeable shares. Each
    HCI exchangeable share is exchangeable for one Homestake common share at any
    time at the option of the holder and has essentially the same voting,
    dividend (payable in Canadian dollars), and other rights as one Homestake
    common share. A share of special voting stock, which was issued to the
    transfer agent in trust for the holders of the HCI exchangeable shares,
    provides the mechanism for holders of the HCI exchangeable shares to receive
    their voting rights.

    Homestake, through a wholly-owned subsidiary, owns all the common shares
    outstanding of Homestake Canada Inc. ("HCI"). At June 30, 2000, HCI had 6.6
    million HCI exchangeable shares outstanding, which were held by the public.

    Following the 1999 business combination with Argentina Gold, Homestake's
    investment in Argentina Gold was transferred to HCI in exchange for a
    Canadian dollar-denominated intercompany note payable by HCI to its parent
    company of approximately C$282 million (US$191 million). In accordance with
    United States generally accepted accounting principles, the assets,
    liabilities and shareholders' equity of Argentina Gold have been recorded in
    HCI's financial statements at the historical cost basis to the parent
    company. The difference between the historical cost basis of Argentina Gold
    shareholders' equity and its fair value at the date of transfer has been
    recorded as a reduction to HCI's shareholders' equity.

13. Subsequent Event

    In July 2000, Homestake purchased Case Pomeroy & Company, Inc.'s ("Case")
    25% interest in the Round Mountain mine for $42.6 million, increasing
    Homestake's ownership of the mine from 25% to 50%. The transaction was
    effected by Homestake purchasing 100% of the shares of Bargold Corporation,
    a wholly-owned subsidiary of Case. Purchase consideration consisted of 2.6
    million newly issued Homestake common shares and $25.9 million in cash. The
    transaction was effective July 1, 2000 and will be accounted for as a
    purchase. Purchase price allocations have not been finalized but are
    estimated at $3.4 million for net working capital and $44.7 million for
    property, plant and equipment, less $5.5 million for accrued reclamation.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results
         -----------------------------------------------------------------------
         of Operations
         -------------


(Unless specifically stated otherwise, the following information relates to
amounts included in the consolidated financial statements without reduction for
minority interests.  Homestake reports per ounce production costs in accordance
with the "Gold Institute Production Cost Standard.")

     The following provides information which management believes is relevant to
an assessment and understanding of Homestake Mining Company's ("Homestake" or
the "Company") consolidated results of operations and financial condition.  The
discussion should be read in conjunction with the Management's Discussion and
Analysis included in Homestake's 1999 Annual Report on Form 10-K.

     On April 29, 1999 Homestake issued 20.9 million common shares to acquire
Argentina Gold Corp. ("Argentina Gold"), a Canadian gold exploration company
whose principal asset is its 60% interest in the Veladero property located in
northwest Argentina.  The business combination was accounted for as a pooling of
interests, and accordingly, the Company's consolidated financial statements
include Argentina Gold for all periods.


RESULTS OF OPERATIONS

SUMMARY

     Homestake recorded losses from continuing operations of $2.7 million ($0.01
per share) and $17.3 million ($0.07 per share) in the quarter and six months
ended June 30, 2000 compared with income from continuing operations of $0.8
million ($0.00 per share) and $1.1 million ($0.01 per share) in the respective
1999 periods.

     Second quarter and year-to-date 2000 results include after-tax foreign
currency exchange losses of $6.2 million ($0.02 per share) and $17.4 million
($0.07 per share), respectively, primarily due to further weakening of the
Australian and Canadian currencies.  Second quarter and year-to-date results in
1999 include after-tax foreign currency exchange gains of $13.9 million ($0.05
per share) and $20.2 million ($0.08 per share), respectively, and non-recurring
charges of $7.0 million ($0.03 per share) and $8.3 million ($0.03 per share),
respectively.  Non-recurring charges in the 1999 second quarter and year-to-date
periods include a $3.5 million write-down of an exploration investment and
business combination expenses associated with the Argentina Gold acquisition.

     Excluding the effect of the foreign exchange gains and losses and the 1999
non-recurring charges, the Company recorded income from continuing operations of
$3.5 million ($0.01 per share) and $0.1 million ($0.00 per share), in the second
quarter and year-to-date 2000 periods, respectively, compared with net losses of
$6.1 million ($0.02 per share) and $10.8 million ($0.04 per share) for the
respective 1999 periods.  The stronger operating results are mainly due to
slightly higher realized gold prices, lower per ounce production costs, and
lower income taxes.

     On July 20, 2000, Freeport-McMoRan Sulphur LLC, the operator and 83.3%
owner of the Main Pass joint venture, located in the Gulf of Mexico, announced a
phased closure of the sulfur operations.  Homestake's 16.7% interest in the
joint venture was reflected as a discontinued operation at June 30, 2000.
Second quarter and year-to-date 2000 losses from discontinued operations
amounted to $13.9 million ($0.05 per share) and $15.3 million ($0.06 per share),
respectively, compared to $0.7 million ($0.00 per share) and $1.9 million ($0.01
per

share) in comparable periods in 1999.  The 2000 second quarter loss included
a non-recurring charge of $12 million, reflecting Homestake's $8.5 million share
of unaccrued reclamation and closure costs and a $3.5 million allowance for
projected operating losses during the shutdown period.  Homestake wrote off the
carrying value of its interest in Main Pass in 1997.  Including losses from
discontinued operations, Homestake recorded net losses of $16.5 million ($0.06
per share) and $32.7 million ($0.13 per share) in the three and six months ended
June 30, 2000 compared with net income $0.1 million ($0.00 per share) and a net
loss of $0.8 million ($0.00 per share) in the respective 1999 periods.

(1)  Ounces produced are expressed on a gold equivalent basis and include 83,500
(90,300 in 1999) ounces of gold and 3.3 million (3.8 million in 1999) ounces of
silver contained in ore and concentrates sold to smelters in the second quarter,
and 167,900 (160,500 in 1999) ounces of gold and 7.1 million (6.7 million in
1999) ounces of silver contained in ore and concentrates sold to smelters in the
year-to-date period.

(2)  Ounces produced include 2,800 and 5,600 in the quarter and year-to-date
periods, respectively, from the Quarter Claim in both 2000 and 1999.

(3)  Includes ounces of gold contained in dore and concentrates.

(4)  For comparison purposes, costs per ounce include estimated third-party
costs incurred by smelter owners and others to produce marketable gold and
silver.

(5)  Includes the effect of insurance proceeds received and credited to
processing costs of $1.1 million in the 2000 second quarter and year-to-date
periods, and $2.6 million and $4.6 million in the 1999 second quarter and year-
to-date periods, respectively.

(6)  Homestake reports per ounce production costs in accordance with the "Gold
Institute Cost Standard".

     Revenues from gold, ore and concentrate sales totaled $170.2 million and
$330.0 million in the second quarter and first six months of 2000, respectively,
compared to $169.1 million and $328.3 million, for the comparable periods in
1999.  Higher 2000 sales revenues reflect slightly higher average realized gold
prices, partially offset by lower sales volumes.  In the second quarter and
year-to-date 2000 periods, 616,100 and 1,184,300 equivalent ounces of gold were
sold at average realized prices of $288 and $291 per ounce, respectively,
compared to 630,900 and 1,185,000 equivalent ounces at average realized prices
of $283 and $290 per ounce a year ago.

     During the 2000 second quarter and year-to-date periods, the Company
produced 589,100 abd 1,185,400 equivalent ounces of gold at average total cash
costs of $185 and $189 per ounce, respectively, compared to 627,300 and
1,186,300 equivalent ounces at average total cash costs of $195 and $194 per
ounce in the comparable periods in 1999. Lower production in the 2000 second
quarter reflects decreased production from the United States and Canadian
operations, partially offset by increased production from the Australian
operations. Year-to-date production in 2000 approximated the prior year as
lower production from United States and Canadian operations was offset by
increased production from Australian operations.

     Production costs for the three and six-month periods ended June 30, 2000
declined to $113.0 and $218.0 million, respectively, from $118.9 million and
$223.2 million for the similar periods in 1999.  Lower costs reflect ongoing
cost containment efforts at the Company's operations and the impact of lower
Australian dollar exchange rates as well as, for the second quarter comparison,
lower production.  Cash costs per ounce during the 2000 second quarter and first
half periods declined by 5% and 3%, respectively, from the corresponding periods
of 1999.

     Homestake has been reporting its gold production and operating costs in
terms of equivalent ounces (co-product reporting) since the Eskay Creek mine
commenced production in 1995.  This approach was adopted due to the significance
of silver production at this mine (approximately 40%-45% of revenue depending on
the relative market values of gold and silver).  Since 1995, it has become more
common in the industry to report gold production using by-product reporting,
where silver revenue is credited against operating costs in the calculations of
costs per ounce.  Either method is acceptable under the Gold Institute
Production Cost Standard.  On a by-product basis, in the second quarter 2000,
Homestake produced 529,900 ounces of gold at an average cash cost of $174 per
ounce and in the first half of the year 1,058,000 ounces at $177 per ounce.



United States
-------------

     United States production decreased 11% to 146,800 during the second quarter
of 2000 compared to 165,400 ounces a year ago, primarily due to lower production
at the Homestake and McLaughlin mines, partially offset by increased production
from the Round Mountain mine. The weighted average United States cash cost
increased 6% to $213 per ounce during the second quarter of 2000 compared to
$201 per ounce a year ago.

     Homestake's wholly-owned Ruby Hill mine continued to be a strong performer,
producing 33,100 ounces at a cash cost of $99 per ounce during the second
quarter of 2000 compared to similar production at a cash cost of $100 per ounce
during the prior year's second quarter.

     Production from the Homestake mine decreased 23% during the second quarter
of 2000 to 44,100 ounces compared to 57,100 ounces a year ago.  The lower
production primarily was due to completion of milling of the remaining open-pit
stockpiles in December 1999 and lower ore grade and recoveries from underground
operations, partially offset by increased underground tonnage.  Production from
the processing of open-pit stockpiles in the 1999 second quarter totaled 6,300
ounces.  Cash costs per ounce during the second quarter of 2000 averaged $268
per ounce compared to $253 per ounce in 1999, primarily due to the absence of
the lower cost open-pit ore.  For the three and six month periods ended June 30,
2000, the average ore grade from underground operations at the Homestake mine
was approximately 10% lower than projected in the mine's 2000 production plan.
The Company is continuing to evaluate the potential causes of this grade
shortfall and various operating alternatives to improve the underground ore
grade.  If it is determined that the ore grade performance cannot be improved,
it is reasonably possible that a portion of the ore reserves at the Homestake
mine

would be rendered uneconomic and the remaining carrying value of the assets
impaired.  At June 30, 2000, the net carrying value of the property, plant and
equipment at the Homestake mine was $18.6 million.

     During the second quarter of 2000, gold production from the processing of
residual stockpiles at the McLaughlin mine decreased 21% to 26,400 ounces at a
cash cost of $239 per ounce compared to 33,600 ounces at a cash cost of $196 per
ounce a year ago.  Lower production and higher unit costs primarily were due to
lower ore grade and recovery as the higher-grade stockpiles were depleted in the
third quarter of 1999.

     Homestake's 25 percent share of production from the Round Mountain mine
increased 8% to 38,200 ounces during the second quarter of 2000 compared to
35,400 ounces a year ago, primarily due to increased tonnage processed on the
dedicated and reusable pads, partially offset by lower production from the mill.
Cash costs per ounce increased 9% to $225 per ounce in the second quarter of
2000, primarily due to marginally lower grades of ore mined and the processing
of higher cost inventories during the second quarter of 2000 compared to the
same period in 1999.  Effective July 1, 2000, Homestake increased its interest
in the Round Mountain mine to 50%.  This additional interest was acquired from
Case Pomeroy and Company, Inc. in exchange for total consideration of $42.6
million, consisting of $25.9 million in cash and 2.6 million common shares of
Homestake.  Included in the purchase price was Case Pomeroy's share of the joint
venture's working capital amounting to approximately $3.4 million.  This
acquisition is expected to add approximately 150,000 ounces to Homestake's
annual gold production, 1.5 million ounces of gold in proven and probable
reserves and 0.5 million ounces of gold contained in mineralized material.



Canada
------

     Canadian gold production decreased 15% to 221,800 ounces during the second
quarter of 2000 from 259,700 ounces in 1999, primarily due to decreased
production at the Eskay Creek mine and the absence of production from the now-
closed Snip mine, partially offset by slightly higher production from the Hemlo
operations.  During the second quarter of 2000, the weighted average total cash
costs per ounce from the Company's Canadian mines declined to $156 per ounce
from $160 per ounce a year ago primarily due to the absence of the higher cost
Snip mine production and operating efficiencies at the Hemlo operations.

     At the Eskay Creek mine, second quarter 2000 production totaled 142,600
gold equivalent ounces at an average cash cost of $138 per equivalent ounce
compared to 162,900 gold equivalent ounces at an average cash cost of $135 per
equivalent ounce a year ago.  Decreased production in 2000 primarily was due to
an extra shipment of ore carried over from the first quarter into the second
quarter in 1999.  Year-to-date production from Eskay Creek in 2000 was 3% higher
than the comparable period in the prior year.  Cash costs per equivalent ounce
increased slightly in 2000 compared to 1999 primarily due to lower ore grades.

     At the Hemlo operations, Homestake's 50% share of second quarter 2000
production from the combined Williams and David Bell mines increased to 79,200
ounces from 76,000 in the prior year, primarily due to increased throughput and
marginally higher grade.  Since June 1999, the Williams and David Bell mines
have been supplying ore to a single mill, which has resulted in the combined
operation achieving higher levels of productivity and lower costs.  The weighted
average cash costs per ounce decreased 6% to $188 per ounce during the second
quarter of 2000 compared to $201 per ounce a year ago.

     During the second quarter of 1999, the Snip mine produced 20,800 ounces of
gold at an average cash cost of $203 per ounce.  All mining and milling
activities at the Snip mine were completed during the second quarter of 1999
as the mine's reserves were depleted.  Active reclamation activities at the
minesite were completed in the fourth quarter 1999.

Australia
---------

     Australian gold production increased 9% to 214,100 ounces during the second
quarter of 2000 compared to 196,200 ounces in the comparable 1999 period,
primarily due to higher production at the Kalgoorlie operations, partially
offset by lower production from the Yilgarn operations and the absence of
production from the Peak Hill mine which was closed in 1999.  During the second
quarter of 2000, Australian weighted average total cash costs per ounce
decreased 17% to $195 per ounce from $236 per ounce during the second quarter of
1999 reflecting the weaker Australian dollar and the increased production from
the Kalgoorlie operations.

     During the second quarter of 2000, Homestake's 50% share of production from
the Kalgoorlie operations increased 39% to 101,000 ounces at a cash cost of $190
per ounce from 72,900 ounces at a cash cost of $278 per ounce a year ago.
Increased production and lower costs were achieved primarily through improved
operating performance, reflecting the resolution of mill gear problems which
hampered operations in the prior year's quarter, and the benefits derived from
owner mining.  The Super Pit operations completed the transition from contract
to owner mining in the first quarter of 2000.  During the 2000 second quarter,
the flotation circuit was upgraded to accommodate additional sulfide ore in
preparation for the ultimate phase-out of the underground Mt Charlotte mine, now
scheduled for the third quarter of 2001.

     At Homestake's 100%-owned Yilgarn operations, consisting of the Plutonic,
Lawlers and Darlot mines, second quarter 2000 production decreased slightly to
113,100 ounces from 116,800 ounces a year ago, primarily due to lower production
at the Lawlers mine, partially offset by higher production at the Darlot mine.
Production at the Plutonic mine in the 2000 second quarter approximated the same
amount as a year ago.  During the second quarter 2000, the weighted average cash
cost at the Yilgarn operations decreased by 7% to $199 per ounce compared to
$213 per ounce in 1999, primarily due to lower costs at the Plutonic and Darlot
mines, partially offset by the higher cost at the Lawlers mine.  Changes in
individual mine production were primarily related to changes in mill head grade.

     At the Peak Hill mine, final reclamation was completed in November 1999.
During the second quarter of 1999, the Peak Hill mine produced 6,500 ounces of
gold at an average cash cost of $179 per ounce.

South America
-------------

     Homestake's share of production at its 51%-owned Agua de la Falda mine
amounted to 6,400 ounces of gold at an average cash cost of $207 per ounce in
the second quarter of 2000 compared to 6,000 ounces at a cash cost of $176 per
ounce in the prior year.  Production increased primarily due to a higher
recovery rate, and cash costs per ounce increased primarily due to higher mining
costs and lower grade.

     Homestake has completed its first field season at the 60%-owned Veladero
project, located in northwestern Argentina.  Based on results from a 175,000-
foot drilling campaign consisting of 178 holes carried out between October 1999
and May 2000, and concurrent metallurgical, hydrological, geotechnical and
environmental studies, Homestake announced on

August 1, 2000 an updated assessment of the proven and probable reserves as well
as mineralized material present on the property. The proven and probable gold
reserves are now estimated to contain 5.5 million ounces of gold (Homestake's
share: 3.3 million ounces) contained in 118.3 million tons of ore grading 0.046
ounces of gold per ton. The reserve, which also contains 0.69 ounces of silver
per ton, is part of the recently announced and much larger mineralized material
totaling 391 million tons at a grade of 0.034 ounces of gold and 0.55 ounces of
silver per ton. When developed, Homestake expects the project to produce
approximately 500,000 ounces of gold (100% basis) per year for at least 10
years. Cash costs, including silver credits, are expected to average
approximately $160 per ounce over the life of the project with lower costs in
the early years. The capital cost at this early stage of project engineering is
estimated at $450 million (100% basis). Veladero is expected to be completed in
2003 and have its first full year of production in 2004. Additional drilling in
this area, scheduled for the next field season, could substantially expand
Veladero's reserves and economies of scale.


Other income for the three and six months ended June 30, 2000 includes foreign
currency exchange losses of $7.8 million and $21.9 million, respectively.  The
foreign currency exchange losses in the six-month period include $12.0 million
related to foreign currency exchange contracts and $9.9 million primarily
related to intercompany advances.  Other income for the three and six months
ended June 30, 1999 includes foreign currency exchange gains of $17.4 million
and $26.8 million, respectively.  The foreign currency exchange gains for the
six-month period in 1999 include gains of $16.9 million related to foreign
currency exchange contracts and $9.9 million primarily related to intercompany
advances.

Depreciation, depletion and amortization expense increased to $70.2 million
during the first six months of 2000 compared to $67.9 million in the comparable
1999 period.  The increase primarily reflects $1.7 million of depreciation
related to the new owner-mining equipment held under capital lease at
Kalgoorlie, and changes in the production mix, including the effect of increases
in production at mines with higher per-unit depreciation and amortization rates.
The 1999 year-to-date production also included production from the now-closed
Snip and Peak Hill mines which had been fully-depreciated in 1998.

Exploration expense for the first six months in 2000 decreased to $19.6 million
from $21.1 million during the corresponding period of 1999 primarily due to
timing differences and the capitalization of development costs at Veladero
effective April 1, 2000 following the determination of reserves, partially
offset by increased exploration at the Rio Frio and Del Carmen properties.

Income and mining tax expense for the first six months in 2000 decreased to $3.1
million compared to $17.1 million for the same period in 1999, primarily due to
the lower pretax results in 2000.  In addition, the first six months of 1999
included a charge of approximately $3 million related to the repatriation of
cash to the United States from the Company's Canadian subsidiaries.  The $3.1
million tax expense incurred in the first six months of 2000 primarily reflects
the geographic mix of pretax income and losses, foreign withholding taxes on
intercompany interest income, and Canadian mining taxes.  The Company's
consolidated effective income and mining tax rate will fluctuate depending on
the geographical mix of pretax income and losses.

Minority interests:  Minority interests' share of losses in consolidated
subsidiaries was $0.8 million for the first six months in both 2000 and 1999.

                        LIQUIDITY AND CAPITAL RESOURCES


     Cash provided by operations totaled $80.1 million during the first six
months of 2000 compared to $39.7 million during the same period in 1999.
Working capital at June 30, 2000 amounted to $259.4 million, including cash and
equivalents and short-term investments of $269 million.

     Short-term investments decreased by $130.5 million during the first six
months of 2000, primarily reflecting an increase in the proportion of
Homestake's interest-bearing portfolio of securities which have an original
maturity of less than three months.

     Capital expenditures increased 28% to $45.7 million during the first six
months of 2000 compared to $35.6 million a year ago.  Capital expenditures in
2000 include approximately $16.2 million at the Yilgarn operations (Plutonic,
Darlot and Lawlers mines) primarily for underground development work, $12.6
million at Kalgoorlie primarily for owner-mining equipment and a flotation
circuit upgrade, $5.8 million for development costs at the Veladero project, and
$4.6 million at the Homestake mine for various infrastructure and other capital
improvements, with the balance primarily related to sustaining capital at the
Company's other operating mines.  Capital expenditures of $35.6 million during
the first six months of 1999 included approximately $18 million at the Yilgarn
operations primarily for underground development work, with the balance
primarily related to underground mobile mining equipment purchases at the
Homestake mine and sustaining capital at the Company's other operating mines.

     The Company has a credit facility ("Credit Facility") providing a total
availability of $430 million.  This facility is available through July 14, 2003
and provides for borrowings in United States, Canadian, or Australian dollars,
or gold, or a combination of these.  At June 30, 2000, Canadian dollar
borrowings under the Credit Facility of $201.2 million (C$297.7 million) were
outstanding.  The Company pays a commitment fee on the unused portion of this
facility ranging from 0.15% to 0.35% per annum, depending upon rating agencies'
ratings for the Company's senior debt.  The credit agreement requires a minimum
consolidated net worth, as defined in the agreement (primarily shareholders'
equity plus the amount of all noncash write-downs made after December 31, 1997),
of $500 million.  Interest on the Canadian dollar borrowings is payable
quarterly and is based on the Bankers' Acceptance discount rate plus a stamping
fee.  At June 30, 2000, this rate was 6.93%.

     Debt repayments, net of borrowings under the Credit Facility during the
first six months of 2000 were $37 million compared to $61 million for the six
months ended June 30, 1999.  Net debt repayments in 2000 reflect the repayment
of $135.0 million of the 5.5% convertible subordinated notes ("Convertible
Notes") which matured on June 23, 2000, and principal payments of $1.2 million
under capital leases, less Canadian dollar-denominated borrowings of $99.2
million (C$149.5 million) drawn under the credit facility.  The repayment of the
Convertible Notes was financed by the Credit Facility borrowings and existing
cash and equivalents.  During the first six months of 2000, the Company also
received $6.7 million of capital lease proceeds related to additional owner-
mining equipment at Kalgoorlie.  In the first six months of 1999, the Company
repaid $149.6 million of Australian dollar-denominated borrowings under the
Credit Facility and $10.0 million of South Dakota pollution control bonds and
repurchased $2.4 million Convertible Notes.  The 1999 debt repayments were
financed with existing cash and equivalents and by Canadian dollar-denominated
borrowings of $101 million (C$150.million) under the Credit Facility.

                   Homestake Mining Company and Subsidiaries


Foreign currency, gold and other commitments

     Homestake's precious metals hedging policy provides for the use of forward
sales contracts to hedge up to 30% of each of the following ten year's expected
annual gold production, and up to 30% of each of the following five year's
expected annual silver production, at prices in excess of certain targeted
prices.  The policy also provides for the use of combinations of put and call
option contracts to establish minimum floor prices.  Homestake does not hold or
issue financial instruments or derivative financial instruments for trading
purposes or to create hedge positions in excess of forecast identifiable
exposures.

     During the second quarter and year-to-date 2000 periods, the Company
delivered or financially settled 51,270 and 142,540 ounces of gold at average
prices of $355 and $335 per ounce, respectively, under maturing forward sales
and option contracts.  In addition, during the first quarter of 2000, the
Company delivered or financially settled 655,000 ounces of silver at an average
price of $6.30 per ounce under maturing forward sales and option contracts.
During the second quarter and year-to-date 1999 periods, the Company delivered
or financially settled 177,500 and 235,000 ounces of gold at average prices of
$312 and $324 per ounce, respectively, and 830,000 and 1,585,000 ounces of
silver at an average price of $6.37 and $6.35 per ounce, respectively, under
maturing forward sales and option contracts.

     In March 2000, the Company closed out and financially settled its then-
remaining US dollar-denominated silver forward sales contracts covering 3.6
million ounces maturing in 2000 and 2001.  The pretax gain of $3.3 million
realized on this transaction was deferred and is being recorded in income as the
originally designated production is sold.  At June 30, 2000, the unamortized
portion of this gain was $2.4 million, of which $0.4 million was classified as
noncurrent.  The noncurrent deferred gain on close-out of forward sales
contracts at June 30, 2000 also includes $28.5 million related to the 1999
close-out of gold forward sales contracts maturing in the years 2001, 2002 and
2003.  An additional $6.5 million of deferred gains on this transaction is
classified as current and is included in accrued liabilities in the accompanying
balance sheet at June 30, 2000.

     The foregoing hedging activities increased revenues in the second quarter
and year-to-date 2000 periods by approximately $4 million and $8 million,
respectively, compared to increases in revenues in the 1999 second quarter and
year-to-date periods of approximately $8 million and $14 million, respectively.

     The Company's hedge portfolio has essentially no unprotected call options,
floating lease rate exposure or margin call requirements.  The estimated fair
value of the Company's remaining gold hedging position at June 30, 2000 is
approximately $12 million and encompasses almost 1.5 million ounces at an
average price of $365 per ounce.

     Under the Company's foreign currency protection program, the Company has
entered into foreign currency option contracts to minimize the effects of a
strengthening of either the Canadian or Australian currencies in relation to the
United States dollar.  Realized and unrealized gains and losses on this program
are recorded in other income.  At June 30, 2000, the Company had a net
unrealized loss of $5.3 million on open contracts under this program.  In July
2000, the Company discontinued its foreign currency protection program.  Option
contracts outstanding at June 30, 2000 are expected to remain in place until
maturity.

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting
for Derivative Instruments and Hedging Activities."  SFAS 133 requires that
derivatives be recognized as assets or liabilities and be measured at fair
value.  Gains or losses resulting from changes in the value of derivatives are
to be accounted for depending on the use of the derivatives and whether they
qualify for hedge accounting as either a fair value hedge or a cash flow hedge.
The key criterion for hedge accounting is that the hedging relationship must be
highly effective in achieving offsetting changes in fair value or cash flows of
the hedging instruments and the hedged items.  SFAS 133 is effective for fiscal
years beginning after June 15, 2000.  In June 2000, the FASB issued SFAS 138,
"Accounting for Certain Derivative Instruments and Certain Hedging Activities,
an amendment of SFAS 133" ("SFAS 138").  Under the amended standard, certain
components of the Company's precious metals hedging program may be excluded from
the accounting requirements of SFAS 133 provided they meet certain criteria to
qualify as a normal purchase and sale transaction.  The Company has not
determined whether its precious metals hedging contracts will meet the criteria
for exclusion.  The Company believes that changes in unrealized gains and losses
on Homestake's derivative activities, to the extent subject to the requirements
of SFAS 133 and SFAS 138, will qualify for hedge accounting and, to the extent
effective, be deferred in other comprehensive income.  However, there are many
complexities to SFAS 133 and SFAS 138, and the Company currently is evaluating
their impact on reported operating results and financial position.  The effects
of adopting the new standard are not reasonably determinable at this time.  The
Company expects to adopt SFAS 133 and SFAS 138 effective January 1, 2001.

     In December 1999, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial Statements
"which outlines the basic criteria required to recognize revenue, and provides
guidance on the presentation and disclosure of revenue in financial statements
filed with the SEC.  SAB 101 is required to be implemented no later than the
fourth quarter of 2000.  The Company is awaiting additional implementation
guidance, which is expected to be issued shortly by the SEC, in order to
evaluate the effect, if any, that this bulletin may have on the consolidated
financial statements.


Gold Prices

     The market price for gold is based on a worldwide market.  Gold prices are
subject to volatile price movements over short periods of time and are
influenced by numerous factors over which Homestake has no control, including
expectations with respect to rates of inflation, the relative strength of the
United States, Canadian and Australian dollars, interest rates, global or
regional political or economic crises, demand for jewelry and industrial
products containing gold, speculation, and sales by central banks and other
holders and producers of gold in response to these factors.

     Future results will be impacted by such factors as the market price of gold
and, to a lesser extent, silver, the Company's ability to expand its ore
reserves, and fluctuations of foreign currency exchange rates.  The Company
believes that the combination of cash, short-term investments, available lines
of credit and future cash flows from operations will be sufficient to meet
normal operating requirements, planned capital expenditures, and anticipated
dividends.

Year 2000 Compliance


     The Year 2000 (Y2K) issue is the result of computerized systems using two
digits rather than four to identify an applicable year.  Date-sensitive systems
may recognize a date using "00" as the year 1900 rather than the year 2000.
This could result in a system failure or miscalculation causing disruptions to
business operations.  In 1999, the Company completed a review of its computer-
based information systems and, where needed, Y2K compliant upgrades for the
Company's core financial systems were installed and tested.  To date, no
significant Y2K problems have been encountered and none are expected.
Homestake's management information systems and operations staff will again
monitor critical operations during the December 31, 2000 - January 1, 2001 Y2K
rollover dates.

(b)  CAUTIONARY STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
     1995


     Certain statements contained in this Form 10-Q that are not statements of
     historical facts are "forward looking statements" within the meaning of the
     Private Securities Litigation Reform Act of 1995.  Such statements are
     based on beliefs of management, as well as assumptions made by and
     information currently available to management.  Forward looking statements
     include those preceded by the words "believe," "estimate," "expect,"
     "intend," "will," and similar expressions, and include estimates of
     reserves, future production, costs per ounce, dates of construction
     completion, costs of capital projects and commencement of operations.
     Forward looking statements are subject to risks, uncertainties and other
     factors that could cause actual results to differ materially from expected
     results.  Some important factors and assumptions that could cause actual
     results to differ materially from expected results are discussed below.
     Those listed are not exclusive.

     Estimates of reserves and future production for particular properties and
     for the Company as a whole are derived from annual mine plans that have
     been developed based on mining experience, assumptions regarding ground
     conditions and physical characteristics of ore (such as hardness and
     metallurgical characteristics), expected rates and costs of production, and
     estimated future sales prices.  Actual production may vary for a variety of
     reasons, such as the factors described above, ore mined varying from
     estimates of grade and metallurgical and other characteristics, mining
     dilution, actions by labor, and government imposed restrictions.  Estimates
     of production from properties and facilities not yet in production are
     based on similar factors but there is a

     greater likelihood that actual results will vary from estimates due to a
     lack of actual experience. Cash cost estimates are based on such things as
     past experience, reserve and production estimates, anticipated mining
     conditions, estimated costs of materials, supplies and utilities, and
     estimated exchange rates. Noncash cost estimates are based on total capital
     costs and reserve estimates, changes based on actual amounts of unamortized
     capital, changes in reserve estimates, and changes in estimates of final
     reclamation. Estimates of future capital costs are based on a variety of
     factors and include past operating experience, estimated levels of future
     production, estimates by and contract terms with third-party suppliers,
     expectations as to government and legal requirements, feasibility reports
     by Company personnel and outside consultants, and other factors. Capital
     cost estimates for new projects are subject to greater uncertainties than
     additional capital costs for existing operations. Estimated time for
     completion of capital projects is based on such factors as the Company's
     experience in completing capital projects, and estimates provided by and
     contract terms with contractors, engineers, suppliers and others involved
     in design and construction of projects. Estimates reflect assumptions about
     factors beyond the Company's control, such as the time government agencies
     take in processing applications, issuing permits and otherwise completing
     processes required under applicable laws and regulations. Actual time to
     completion can vary significantly from estimates.

     See the Company's Form 10-K Report for the year ended December 31, 1999,
     "RISK FACTORS" and "CAUTIONARY STATEMENTS" included under Part I - Item 1,
     for a more detailed discussion of factors that may impact on expected
     future results.
