PRESS RELEASE - NEW YORK, SEPTEMBER 17, 2002
For Immediate Release
All amounts in United States dollars

Barrick Sets Out New Growth Plan

--------------------------------------------------------------------------------
Announcement Highlights

o    Planned $2-billion mine development program

o    Expected to contribute 2 million ounces at $125 per ounce

o    Continued high levels of production expected from current operations

o    A goal of doubling earnings by 2006, based on $325 gold price,
     significantly improving ROE

o    Forward Sales position expected to be reduced by one-third to 12 million
     ounces by end of 2003

--------------------------------------------------------------------------------

Barrick Gold Corporation (ABX: NYSE/TSE) announced today a new growth plan
designed to make the Company the world's largest and most profitable gold
producer, and the industry's major growth stock.

     Barrick's growth plan draws on the financial strength provided by the
Company's $1 billion cash balance, A-rated balance sheet and expected free cash
flows of $500 million annually from its operating mines supported by a
12-million-ounce forward sales position.

DEVELOPMENT OF PIPELINE TO MAKE BARRICK INDUSTRY'S MAJOR GROWTH STOCK

"We expect this to be one of the largest development programs ever undertaken by
a gold producer," said Randall Oliphant, President and Chief Executive Officer.
"The unique position we are in today is the culmination of our focus on
acquiring quality mines and exploration and development properties during a
period of weak gold prices and developing them as gold prices strengthen, using
our development expertise."

     The five-year, $2-billion development plan calls for an average 2 million
ounces of additional annual gold production for the first ten years at expected
cash costs of $125 per ounce - 29% lower costs than the current production base
- maintaining Barrick's low cost position in the industry.

     The following are expected start-up dates, average annual production rates,
and cash costs for the four projects over their first decade:

o    Alto Chicama (2005): 500,000 ounces at $130 per ounce;

o    Cowal (2005): 270,000 ounces at $170 per ounce;

o    Veladero (2006): 530,000 ounces at $155 per ounce; and

o    Pascua-Lama (2008): 800,000 ounces at $85 per ounce.

     Overall, higher production and lower costs are expected in the initial
years. In the case of Alto Chicama, the operating cost estimates are based on
assumptions related to its Pierina-like similarities in geology and metallurgy.

     Under the plan, Barrick's net production is expected to rise by 1.2 million
ounces, or 21%, to 6.9 million ounces in 2006 at lower costs. As a result, the
Company is targeting a doubling of earnings by 2006 based on a $325 gold price.
Barrick's four new projects are estimated to have an internal rate of return of
14% at

BARRICK GOLD CORPORATION                                           PRESS RELEASE

<PAGE>

$325 gold (11% at $300 gold) - well above its 8% cost of capital.

     "Strong top and bottom line growth positions Barrick as the only growth
stock among major gold producers," said Mr. Oliphant. "Our growth plans couldn't
come at a better time. As the industry faces declining production and rising
costs, we stand to benefit the most from rising gold prices. We are the only
major gold company to set out four-year growth metrics for earnings competitive
with top performing growth companies in any industry sector. "

CONTINUES TO REDUCE HEDGING - FORWARD SALES POSITION EXPECTED TO DECLINE BY
ONE-THIRD BY END OF 2003

In light of the current environment, Barrick also announced plans to reduce its
forward sales position, primarily through scheduled deliveries from production.
As a result, the Company anticipates a reduction in its forward sales position
from 17.9 million ounces to a target of 12 million ounces by the end of next
year, based on market conditions. This equates to 15% of the Company's current
gold reserves as compared to 22% at present. The Company also plans to continue
to reduce its call option and variable price sales contract position, with a
target of 1.5 million ounces by the end of 2003.

     "We are further reducing our hedge position for three main reasons: 1)
interest rates are at 40-year lows, leading to lower forward premiums; 2)
Barrick has never been stronger financially; and 3) the outlook for gold prices
is positive," said Jamie Sokalsky, Senior Vice President and Chief Financial
Officer.

     Mr. Oliphant added: "This is an exciting new time in the history of Barrick
and the gold industry. Barrick's growth plan makes us uniquely positioned to
benefit from strengthening gold prices."

     As well as having a pipeline of new projects, Barrick has stepped up its
exploration and development budget to $95 million in 2002, the largest in the
industry.

     The Company will be providing detailed updates on each new project in the
coming months as it advances project development, including optimizing
feasibility studies, permitting and further expanding the reserve base.

     Barrick is a leading international gold producer with the industry's only
A-rated balance sheet, a portfolio of long-life, low-cost operations on four
continents and proven and probable reserves of 82.3 million ounces of gold.
Barrick's shares are traded under the ticker symbol ABX on the Toronto, New
York, London and Swiss Stock Exchanges and the Paris Bourse.

                   At a Glance - Barrick Development Projects*

ALTO CHICAMA

Description:

o    Located in North-central Peru, about 175 km from Barrick's Pierina Mine.

o    Oxide mineralization similar to Pierina, with high-grade gold surface
     outcroppings and good metallurgy.

Background:

o    Barrick announced the Alto Chicama discovery on April 23, 2002, and after
     an intensive drill program focused on the Property's Lagunas Norte deposit,
     and more than doubled the inferred resource estimate on July 10.

Current Mineralization Status:

o    Updated resource classification as at September 16, 2002: indicated
     resource totaling 103 million tons of ore; grade: 0.056 oz/ton; 5.74
     million oz and inferred resource totaling 33 million tons; grade .046
     oz/ton; 1.53 million ounces(1).

o    Resource remains open to the south and southeast.

Activities Underway:

o    2002 exploration budget increased to $35 million from initial $5 million.

o    Program focused on infill and step out drilling at Lagunas Norte to expand
     resource.

o    Additional drills are targeting gold showings identified within 15km radius
     of discovery.

o    Conducting metallurgical test work and mine and process planning.

Timeline:

o    Feasibility study scheduled for 2003.

o    Exercise of option to acquire mineral rights expected in 2003.

o    Filing of permit applications anticipated in 2003 with the submission of
     the feasibility study.

o    Construction targeted to begin in late 2003/ early 2004.

o    Production targeted 2005.

Capital Cost Estimate:

o    Capital cost estimate based on assumptions related to similarity with
     Pierina deposit and expected similarity of process design etc. would result
     in capital costs in the $300 to $350 million range.

o    Capital costs are expected to rise if the resource continues to expand.

Production Profile:

o    Based upon Pierina performance, the production profile is expected to
     average 500,000 oz/year at $130/oz cash cost over first decade.

o    Higher production and lower costs are expected in the earlier years as
     mining begins on high-grade surface outcroppings.

1. Resource calculations were prepared by employees of Barrick under the
   supervision of Alexander J. Davidson, P. Geol, Senior Vice President,
   Exploration of Barrick, and Alan R. Hill, P. Eng, Executive Vice President,
   Development of Barrick. The resource has been calculated on a block modeling
   basis, using blocks of 10x10x5 meters and a cut-off grade of 0.50 g/tonne
   (0.14 oz/ton) for oxide mineralization and 0.75 g/tonne (.022 oz/ton) for
   sulphide mineralization. A total of 298 diamond drill holes have been drilled
   and assayed in the area of interest. Drill hole spacing averages between 50
   and 100 meters. A drill hole radius of 50 meters was used for purposes of
   calculating the resource. Resources which are not reserves do not have
   demonstrated economic viability. For additional information see Barrick's
   press release of April 23rd and July 10, 2002.

   purposes, Industry Guide 7 (under the Securities Exchange Act of 1934), as
   interpreted by the Staff of the SEC, requires completion of a full
   feasibility study in order to classify mineralization as a reserve.
   Accordingly, for U.S. reporting purposes, the mineralization at Veladero is
   classified as indicated resources.
