BARRICK AND HOMESTAKE ANNOUNCE MERGER PLAN US$2.3 BILLION SHARE EXCHANGE TO
CREATE INDUSTRY LEADER

TORONTO, JUNE 25, 2001 . . . Barrick Gold Corporation and Homestake Mining
Company today announced plans to merge, creating a new leader in the gold
industry - both in quality and scale. The combined company is expected to have
a market capitalization of US$9 billion, double that of the nearest
competitor. It will be the second largest gold producer with the lowest cash
costs of any major producer and have approximately US$900 million in cash. The
merged company's earnings and cash flow are expected to be the highest in the
industry.
     "This strategic merger combines the operational, financial and human
resources of two great companies to create the preeminent global gold mining
company," said Randall Oliphant, President and Chief Executive Officer of
Barrick. "We are establishing a platform to build on, with strengths that
better position us to generate profitable growth."
     "We are teaming up with the financially strongest partner," said Jack
Thompson, Chairman and Chief Executive Officer of Homestake. "This merger is
the next natural step in a process that has seen Homestake transform itself
from a high-cost, U.S. asset-based company, to a low-cost, global producer
over the last decade."

PREMIUM OFFERED
     Under the merger agreement, Barrick is offering to exchange 0.53 of a
Barrick share for each of Homestake's 263.3 million outstanding shares, which
represents a value of US$8.71 for each Homestake share. This is a premium of
31

per cent based on the June 22, 2001 closing price of US$6.65 for Homestake
shares on the New York Stock Exchange and a premium of 27 per cent based on
the US$6.87 average closing price of Homestake's shares over the last 10
trading days. Following the merger, holders of exchangeable shares of
Homestake Canada will be entitled to exchange their shares into Barrick common
shares based on the same ratio.
     The Boards of Directors of both companies have unanimously approved the
transaction. Barrick has signed commitment agreements with certain
shareholders and directors of Homestake, who hold approximately 12% of
Homestake's outstanding shares and have agreed to vote in favor of the merger.
     The transaction is intended to be tax-free for U.S. income tax purposes
and is subject to regulatory and Homestake shareholder approvals. No approval
by Barrick shareholders is required. The transaction is planned to be treated
as a pooling of interests under U.S. Generally Accepted Accounting Principles
(GAAP) and is expected to close in the fourth quarter of 2001.
     Since the transaction will further increase Barrick's United States
shareholder base, and in order to bring the company in line with its peer
group, Barrick will adopt U.S. GAAP as its primary basis of communicating
financial results upon completion of the merger.

COMPLEMENTARY ASSETS
     "Homestake's high-quality, low-cost assets are very complementary to
Barrick's. Our production profile is enhanced by Homestake's annual production
of approximately 2 million ounces at similar low costs," said Randall
Oliphant. "In addition to becoming the largest producer in Canada and the
United States, we will be the second-largest producer in Australia."
     "This transaction opens a new chapter in Homestake's 125-year history,"
said Jack Thompson, who becomes a member of the Board of Directors of the
merged company. "Our great legacy will be carried on in a combined company
that will reinforce Homestake's long-held tradition of operating excellence,
technical innovation and financial strength."

LEADER IN QUALITY AND SCALE
     In terms of financial strength, the merged company is expected to have:

     o    Industry-high earnings and cash flows; backed by





Barrick Gold Corporation                                           Page 3 of 4

     o    The industry's only A-rated balance sheet; and

     o    A Premium Gold Sales Program that offers protection during periods
          of low gold prices, while maintaining complete flexibility to
          participate in higher prices.
               With the inclusion of Homestake's 2-million-ounce hedge
               position, the merged entity will have a combined gold forward
               sale position totaling 18 million ounces, at an average annual
               minimum price of US$345 per ounce. This is roughly three years
               of production and 22 per cent of reserves, providing floor
               price protection on approximately two-thirds of production
               through 2003 and a declining portion thereafter. The combined
               position provides a comfortable level of gold price protection
               for the merged entity, and is in line with the historic
               parameters of Barrick's program.
          Based on 2000 pro forma results, the combined company had:
     o    Production totaling 6 million ounces of gold at cash costs of US$156
          per ounce, the lowest of any major gold producer; with a
     o    Reserve base of 79 million ounces, among the least sensitive to
          lower gold prices in the industry.

FINANCIALLY ACCRETIVE
     The merger is expected to create annual cost-saving synergies of
approximately US$55 million (after-tax) beginning in 2002. The majority of
these savings will be realized in the tax, exploration and administrative
areas. "With the operating and financial synergies for shareholders, this
transaction is expected to be financially accretive for both Barrick and
Homestake," said Randall Oliphant. A joint integration team has been formed to
maximize synergies and to ensure efficient integration of the newly merged
company.

LEADING PRODUCER IN LOW-RISK LOCATIONS
     The merger creates a company with low geo-political risk, with 54% of its
reserves in North America and Australia, 33% in South America, and 13% in
Tanzania.
     Based in Toronto, the merged company's major properties will include:
Barrick's Goldstrike Property in Nevada, Pierina Mine in Peru and Bulyanhulu
Mine in Tanzania, and Homestake's Eskay Creek and Hemlo Mines in Canada and
Kalgoorlie Mine and Yilgarn Operations in Australia.

     The combined company will also have an attractive pipeline of projects
that provide excellent leverage to a rising gold price. These include a
combined resource of 35 million ounces at Barrick's Pascua-Lama Project on the
Chile/Argentina border and the adjacent Veladero District, owned 60 per cent
by Homestake and 40 per cent by Barrick before the merger.
     Homestake produced 2.2 million ounces of gold at a cash cost of US$174 an
ounce in 2000. At year-end 2000, the company had gold reserves of 20.8 million
ounces.
     Barrick produced 3.7 million ounces of gold in 2000 at a cash cost of
US$145 an ounce. At year-end 2000, the company had gold reserves of 58.5
million ounces.
