                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.  INTRODUCTION

The Company, which is incorporated in British Columbia, presents all financial
statements in United States dollars and under generally accepted accounting
principles as practiced in the United States for interim financial information,
and the instructions for Form 10-Q applicable to a going concern, which
principles, except as otherwise disclosed, assume that assets will be realized
and liabilities will be discharged in the normal course of business.  The
Registrant and certain of its subsidiaries (collectively, the "Debtors") filed
petitions for relief under Chapter 11 of the United States Bankruptcy Code on
January 16, 1998 (the "Filing").  The Debtors are presently operating their
business as debtors-in-possession subject to the jurisdiction of the United
States Bankruptcy Court for the District of Nevada (the "Bankruptcy Court").

These unaudited consolidated financial statements should be read in conjunction
with the financial statements and notes thereto included in the Company's Annual
Report on Form 10-K.  In the opinion of management, the financial information
set forth in the accompanying unaudited interim consolidated financial
statements reflects all adjustments necessary for a fair statement of the
periods reported, and all such adjustments were of a normal and recurring
nature.

2.   REORGANIZATION CASE

Substantially all liabilities as of the date of the Filing are subject to
resolution under a plan of reorganization to be voted upon by the Debtors'
creditors and confirmed by the Bankruptcy Court.  Amended and Restated schedules
have been filed by the Debtors with the Bankruptcy Court setting forth the
assets and liabilities of the Debtors as of the date of the Filing as shown by
the Debtors' accounting records.  Differences between amounts shown by the
Debtors and claims filed by creditors will be investigated and reconciled.  The
amount and settlement terms for such disputed liabilities are subject to
allowance by the Bankruptcy Court.  Ultimately, the adjustment of the total
liabilities of the Debtors remains subject to a Bankruptcy Court approved plan
of reorganization, and, accordingly, the amount of such liabilities is not
presently determinable.

Under the Bankruptcy Code, the Debtors may elect to assume or reject real estate
leases, employment contracts, personal property leases, service contracts and
other executory pre-petition contracts, subject to Bankruptcy Court approval. 
The Debtors continue to review leases and contracts and cannot presently
determine or reasonably estimate the ultimate outcome of, or liability resulting
from, this review.  Additional information with respect to the Debtors' Chapter
11 case is set forth in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1997.

On July 17, 1998, a Joint Plan of Reorganization (the "Plan") was filed with the
Bankruptcy Court for four of the individual debtor entities, Diamond Hill
Mining, Inc.  (DHMI), Montana Tunnels Mining, Inc.  (MTMI), Florida Canyon
Mining, Inc.(FCMI), and Pegasus Gold International, Inc.  (PGII).  The Plan
calls for the reorganized PGII to be redomesticated in Delaware and to become
the corporate parent of reorganized DHMI, FCMI, and MTMI.  Priority claims and
convenience claims (vendors with claims under $10,000) will be paid in full, in
cash.  Other vendor claims will be paid cash equal to 75 percent of the claim
amount with the remainder paid in common stock of reorganized PGII.  Guaranty
claims in respect of the Revolving Credit Agreement, guaranty claims in respect
of foreign exchange contracts, and Pegasus Gold Corp.  claims will be paid in
common stock of reorganized PGII.  The Plan must be accepted by each class of
allowed claims whose rights are impaired.  A class is deemed to have accepted
the Plan if creditors holding at least two-thirds in amount and one-half in
number of the allowed claims have voted for the Plan.  A hearing date has been
set for August 25, 1998 to approve the content of the Disclosure Statement
respecting the Plan.  The Bankruptcy Court has fixed October 8, 1998 as the date
for a hearing on the confirmation of the Plan.  Upon confirmation of the Plan, a
consummation date will be established.

On July 31, 1998, a Joint Liquidating Plan of Reorganization (the "Liquidating
Plan") was filed with the Bankruptcy Court for the remaining fourteen debtors in
bankruptcy, including Pegasus Gold Inc., Pegasus Gold Corp., and the other non-
operating debtors.  The Liquidating Plan provides for the separate liquidation 

                                                                              7

of each debtor, such that each debtor's estate will be liquidated and
distributions made to holders of allowed claims against that debtor.  The
Liquidating Plan does not provide for substantive consolidation of the debtors.
Priority claims will be paid in full, in cash.  Secured claims will either
remain unaltered, satisfied by agreement, or the collateral will be abandoned to
the claimant.  General unsecured claims will receive a pro rata distribution of
available remaining cash.  A hearing date has been set for September 11, 1998 to
approve the content of the Disclosure Statement respecting the Liquidating Plan.
The date for a hearing on the confirmation of the Liquidating Plan has not yet
been established.

If the Plan and the Liquidating Plan are not confirmed, there can be no
assurance that the debtors or any other parties in interest would be able to
formulate and confirm any other plans.

6.   RECENT ACCOUNTING PRONOUNCEMENTS

In June 1997, Statement of Financial Accounting Standards No.  130 (SFAS 130),
"Comprehensive Income", was issued.  SFAS 130 establishes standards for
reporting and display of comprehensive income and its components in a full set
of general-purpose financial statements.  SFAS 130 is effective for fiscal years
beginning after December 15, 1997, and requires restatement of earlier periods
presented.  The Company has applied this standard effective January 1, 1998.

In June 1998, Statement of Financial Accounting Standards No.  133 (SFAS 133),
"Accounting for Derivative Instruments and Hedging Activities", was issued. 
SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, (collectively referred to as derivatives) and for hedging activities.
It requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value.  SFAS 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999.

                   FINANCIAL CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

OVERVIEW

The Registrant and certain of its subsidiaries (collectively, the "Debtors")
filed petitions for relief under Chapter 11 of the United States Bankruptcy Code
on January 16, 1998 (the "Filing").  The Debtors are presently operating their
business as debtors-in-possession subject to the jurisdiction of the United
States Bankruptcy Court for the District of Nevada (the "Bankruptcy Court").  As
a result of the Filing, the cash requirements for the payment of accounts
payable and other liabilities that arose prior to the Filing are in most cases
deferred until a plan of reorganization is approved by the Bankruptcy Court.

The Company recorded a net loss of $10.2 million ($0.25 per share) in the second
quarter of 1998, compared  to a net loss of $3.2 million ($0.08 per share)
during the same period in 1997.  The increased loss is the result of a 27
percent decline in production, a 32 percent decrease in the realized price per
ounce of gold, and $2.4 million in net charges for reorganization items,
combined with a decrease of $0.8 million in other income. These items were only
partially offset by a 10 percent decrease in total production costs per ounce,
and lower general and administrative, exploration, and care and maintenance
expenses.  The loss before reorganization items and income taxes for the second
quarter of 1998 was $7.9 million ($0.19 per share).

The year-to-date net loss of $20.4 million ($0.49 per share) is worse than the
1997 loss for the same period of $3.2 million ($0.08 per share) due to lower
production, lower realized prices for gold, reorganization items, and a decrease
in other income.

GOLD PRODUCTION

The following chart details gold production, cash costs and total production
costs per ounce by location for the three months and six months ended June 30,
1998 and 1997:

___________
(1)  Effective January 1, 1997, the Company adopted the gold production cost
     standard developed by the Gold Institute in order to facilitate comparisons
     among companies in the gold industry.  Cash production costs reported in
     prior periods have been restated as cash operating costs and total cash
     costs in accordance with the new standard.  Cash operating costs calculated
     under the new standard include all operating costs (including overhead) at
     the mine sites, but exclude royalties, production taxes and reclamation and
     are reported net of by-product credits.  Total cash costs include royalties
     and production taxes, but exclude reclamation.  Total production costs
     remain unchanged and include reclamation in addition to depreciation,
     depletion and amortization.

REVENUES

GOLD:  Revenue from the sale of gold decreased 50 percent to $20.4 million
during the second quarter of 1998 as a result of a 27 percent decline in gold
production and a 32 percent decrease in the realized price per ounce.  Lower
production reflects the fact that the Company has shutdown operations at Mt.
Todd, Beal Mountain, Zortman, and Black Pine which added 24,297 ounces to
commercial production during the second 

                                                                            11


<PAGE>

quarter of 1997.  Year-to-date gold revenue has decreased 51 percent as a 
result of lower production and lower realized prices.

Average realized gold prices for the second quarter of 1998 and 1997 were $300
and $441 per ounce, respectively, compared to average second quarter COMEX gold
prices of $300 and $343 in 1998 and 1997, respectively.  The decline in the
average realized gold prices per ounce during the quarter and for the year-
to-date is the result of the closeout of all of the Company's forward sales
contracts during December 1997 and January 1998.

OTHER METALS:  Sales of other metals decreased $2.9 million to $6.6 million in
the second quarter of 1998.  Lower production of all metals, combined with
decreased prices for zinc and lead, were only partially offset by higher
realized prices for silver.  Realized prices were $5.41 per ounce, $0.47 per
pound, and $0.22 per pound for silver, zinc, and lead, respectively, compared to
$4.85, $0.56, and $0.24, respectively, in the second quarter of 1997.  

Year-to-date revenue from the sale of other metals decreased 20 percent to $14.2
million as a result of lower production of silver and lead and lower realized
prices for zinc and lead.  Realized prices were $5.57 per ounce, $0.46 per
pound, and $0.25 per pound through the first six months of 1998, compared to
$4.67, $0.55, and  $0.27, respectively during the same period in 1997.

OPERATING COSTS

The average total cash cost of production decreased seven percent to $273 per 
ounce of gold in the second quarter of 1998 from $295 per ounce in the second 
quarter of 1997.  For the year-to-date, total cash costs decreased 13 percent 
to $258 in 1998 compared to $296 in 1997.  Decreased cash costs reflect 
higher by-product credits per ounce year-to-date, lower royalties, and the 
shutdown of operations at Mt. Todd, Zortman, Black Pine, and Beal Mountain, 
which were high-cost mines during 1997.  Total cash costs per ounce at 
Florida Canyon decreased 15 percent.   In 1997, the site was mining harder, 
more abrasive ore, resulting in higher mining and crushing costs.  At Montana 
Tunnels, cash costs increased slightly during the quarter as a result of 
lower by-product credits per ounce. For the year-to-date, total cash costs 
are 15 percent below the prior year due to higher by-product credits per 
ounce, lower unit costs of production and lower royalties.  Higher total cash 
costs at Black Pine for the year-to-date are attributable to the lower 
production associated with residual leaching.  At Diamond Hill, 1997 cash 
costs for the second quarter and year-to-date are the result of settlement 
adjustments of previously shipped ore.  No batches were run in the first six 
months of 1997.  In 1998, the high cash costs are due to lower grade ore 
processed in the June campaign.

Depreciation and amortization charges decreased 17 percent to $85 per ounce in
the second quarter of 1998, compared to $103 per ounce in 1997.  For the year-
to-date, depreciation and amortization charges decreased from $104 per ounce in
1997 to $84 per ounce in 1998.  The decrease reflects the property write-downs
recorded in the third and fourth quarters of 1997, which significantly reduced
the Company's property, plant, and equipment balances.

Exploration and evaluation expenses of $0.6 million in the second quarter of
1998 are 49 percent lower than during the same period in 1997 due to cutbacks in
program expenditures in South America and lower overall planned expenditures for
exploration.  For the year-to-date, expenses of $1.4 million are 42 percent
below the first six months of 1997.

Care and maintenance costs decreased to $0.1 million in the second quarter of
1998, compared to $1.6 million during the same period in 1997.  The decrease
reflects the accrual of expenses at Zortman in the fourth quarter of 1997 in
conjunction with property write-offs recorded, and the accrual of remaining mine
closure and reclamation costs.  The costs incurred thus far in 1998 represent
land holding costs at Pullalli pending completion of the sale of that property.

Compared to 1997, general and administrative expenses decreased 21 percent to
$1.8 million in the second quarter of 1998 and 22 percent to $3.9 million for
the year-to-date, primarily as a result of fewer employees, reduced outside
fees, decreased travel costs associated with the Company's foreign operations,
and an overall cost savings program undertaken at the corporate level. 
Professional fees incurred as a result of the 

12


<PAGE>

Filing are separately classified as reorganization items in the Consolidated 
Statement of Income and Comprehensive Income.

OTHER INCOME (EXPENSE) AND TAXES

Interest income for the first and second quarters of 1998 has been classified as
a reorganization item.  The interest was earned on cash balances accumulated due
to the deferral of payments to creditors as a result of the Filing.  Cash and
cash equivalents in the first six months of 1998 included proceeds from the
closeout of the Company's forward contracts in December 1997 and January 1998.

Interest expense in the second quarter of 1998 was unchanged from the same
period in the prior year.  In 1997, all interest associated with the Revolving
Credit Facility (the "Revolver") and the Convertible Subordinated Notes (the
"Notes") was capitalized against the construction of the Mt. Todd Project. 
Interest expense for 1997 represents interest on capital lease obligations.  In
1998, interest expense includes interest accrued on outstanding debt balances in
the pre-petition period from January 1 to January 15, 1998, as well as interest
on capital lease obligations for the first and second quarters.  No interest has
been accrued on the Revolver or the Notes since the Filing. There was no
interest capitalized in the first six months of 1998. 

The Company has also recorded $0.9 million in losses from the sale of its shares
in Argosy Mining ($0.1 million) and the write-off of its investment in Dakota
Mining ($0.8 million).

The Company recorded a charge of $3.5 million associated with the write-off of
remaining deferred debt issuance costs associated with the Notes and the
Revolver.  This charge has been classified as a reorganization item.

The Company has classified $4.5 million of professional fees related to the
Chapter 11 proceedings incurred in the first six months of 1998 as a
reorganization item.  This amount includes $2.9 million recorded in the second
quarter.

Equity in net income of affiliates in 1997 is comprised of the Company's
proportionate share of earnings from the Emerging Markets Gold Fund, which was
liquidated and its assets distributed in the second quarter of 1997.

FINANCING, CAPITAL INVESTMENT, AND LIQUIDITY

At June 30, 1998, the Company had working capital of $58.6 million.  Cash and
cash equivalents totaled $26.2 million at June 30, 1998, compared to $22.6
million at the end of 1997.

OPERATING ACTIVITIES

Cash flow used in operating activities was $2.5 million for the first half of
1998, compared to cash flow generated from operations of $24.8 million during
the same period in 1997.  Decreased cash flow from operations is due to lower
production and lower realized prices for gold.  Cash flow used in operations
before working capital changes was $8.2 million for the first six months of 1998
compared to cash flow generated from operations of $19.6 million for the same
period in 1997.

INVESTING ACTIVITIES

During the first half of 1998, the Company invested $1.6 million in property,
plant and equipment, compared to $48.7 million in 1997.  1998 expenditures have
primarily been for leach pad expansion at Florida Canyon and development at
Diamond Hill.  1997 expenditures included $24.4 million for expansion at Mt.
Todd, $4.4 million at Florida Canyon, $2.8 million at Pullalli, $2.9 million at
Zortman, $6.5 million at the Company's other operating mine sites and corporate
office, and $7.7 million of capitalized interest. 

FINANCING ACTIVITIES

Cash flow provided by financing activities for the first half of 1998 includes
$35.7 million received from the closeout of forward contracts in January 1998,
less repayment of $26.3 million under the Revolver resulting 

                                                                            13


<PAGE>

from the set off of proceeds received on the closeouts.  During 1997, cash 
flows from financing activities included borrowings under the Revolver of 
$19.6 million and $0.8 million raised from the issuance of common stock to 
the employee savings plan and through stock option exercises. 

CONCLUSION

The Company believes that the $26.2 million in cash and cash equivalents on hand
will be adequate to meet its current liquidity and capital expenditure
requirements; however, cash flow generated by or used in operations is subject
to certain risks that could materially impact available cash.  Until a plan of
reorganization is approved, the Company's long-term liquidity and the adequacy
of its capital resources cannot be determined.

YEAR 2000

As a result of the Company's uncertain future, the Company has not yet completed
a review of its computer-based operations and financial systems for the purpose
of developing a plan that will ensure that all of these systems will be Year
2000 compliant, nor has management determined what the potential cost of
compliance might be.  The Company expects to begin implementation of any
necessary corrective measures in the fourth quarter of 1998.

SAFE HARBOR

Some of the statements contained in this report are forward-looking 
statements, such as estimates and statements that describe the Company's 
future plans, objectives or goals, including words to the effect that the 
Company or management expects a stated condition or result to occur.  Since 
forward-looking statements address future events and conditions, by their 
very nature, they involve inherent risks and uncertainties.  Actual results 
in each case could differ materially from those currently anticipated in such 
statements by reason of factors such as production at the Company's mines, 
changes in operating costs, changes in general economic conditions and 
conditions in the financial markets, changes in demand and prices for the 
products the Company produces, litigation, legislative, environmental and 
other judicial, regulatory, political and competitive developments in areas 
in which the Company operates, and technological and operational difficulties 
encountered in connection with mining activities.
