          A press release was issued by Barrick Gold Corporation ("Barrick") on

ITEM 4:   SUMMARY OF MATERIAL CHANGE

          On January 18, 2005, Barrick received confirmation from the Peruvian
tax authority, SUNAT, that it would not be appealing the Tax Court's decision in
favour of Barrick regarding SUNAT's tax assessment of Barrick's Pierina Mine for
the 1999 and 2000 fiscal years. As a result of SUNAT's confirmation, Barrick
recognized a US$141 million reduction in current and deferred tax liabilities
and a US$21 million reduction of other costs. The effect of this gain was
recorded in Barrick's fourth quarter, 2004 financial results.

ITEM 5:   FULL DESCRIPTION OF MATERIAL CHANGE

          On December 27, 2002, Minera Barrick Misquichilca S.A. ("MBM"), an
indirect, wholly-owned subsidiary of Barrick, received an income tax assessment
of US$41 million from the Peruvian tax authority SUNAT. On July 9, 2003, the
assessment was reduced to US$32 million, excluding interest and penalties, upon
SUNAT's acceptance of part of the claim submitted by MBM. The tax assessment
related to a tax audit of Barrick's Pierina Mine for the 1999 and 2000 fiscal
years. The assessment mainly related to the revaluation of the Pierina mining
concession for the purpose of determining its tax basis. Under the valuation
proposed by SUNAT, the tax basis of the Pierina assets would change from what
was previously assumed, with a resulting increase in current and deferred income
taxes. The full life of mine effect on

Barrick's current and deferred income tax liabilities of US$141 million was
fully recorded at December 31, 2002, as were other related payments of
approximately US$21 million due for periods through 2003.


          On September 30, 2004, the Tax Court notified Barrick of its decision
on the matter in Barrick's favour. On January 18, 2005, Barrick received
confirmation from SUNAT that it would not be appealing the Tax Court's decision.
As a result of SUNAT's confirmation, Barrick recognized a US$141 million
reduction in current and deferred tax liabilities and a US$21 million reduction
of other costs. The effect of this gain was recorded in Barrick's fourth
quarter, 2004 financial results.
