BHP Limited (BHP) today announced a cash offer of C$21.00 per share for all of
the outstanding Class A Subordinate Voting Shares ("Class A Shares") and Class
B Multiple Voting Shares ("Class B Shares") of Dia Met Minerals Ltd (Dia Met).
The BHP offer is supported by the Dia Met Board of Directors and values Dia
Met's equity at C$687 million (approximately A$897 million) on a fully diluted

Dia Met is a publicly traded Canadian mineral exploration and development
company with a primary focus on diamonds.  The company's principal asset
is a 29 per cent joint venture interest in the Ekati TM diamond mine, Canada's
first commercial diamond mine.  BHP is the operator of the Ekati TM diamond
mine and owns a 51 per cent joint venture interest.  Mr Charles Fipke and
Mr Stewart Blusson own 10 per cent of the joint venture respectively.

Acquisition of the additional 29 per cent interest in the Ekati TM joint
venture is strategically important to BHP and its plans for the marketing of
Ekati TM diamonds, including continuation of current branding initiatives,
and the development of new marketing initiatives on a larger scale than would
otherwise be possible.  Given the success of Ekati TM diamonds in the
marketplace and BHP's own marketing efforts, a consolidation of ownership of
this asset is considered an excellent outcome.

The Dia Met Board of Directors has unanimously agreed to recommend the offer
to its shareholders and will co-operate to implement the transaction.  Dia Met
has represented to BHP that it believes all of the Directors and senior
officers of Dia Met intend to tender their shares to the offer.  In addition,
major Dia Met shareholders, Marlene Fipke and David Mackenzie, who together
own approximately 20 per cent of the Class A Shares and 39 per cent of the
Class B Shares, calculated on a fully diluted basis, have irrevocably agreed
to tender their shares to the offer.  Dia Met has agreed to not solicit any
competing offer and has further agreed to pay a termination fee of C$20
million to BHP in certain circumstances.

The Dia Met Board initiated the auction process on 17 October, 2000 after
being advised that Mrs Fipke and Mr Mackenzie were seeking to sell their
shares in the company.

President BHP Minerals Ron McNeilly said: "The Ekati TM diamond mine is a
world class asset and BHP has previously indicated its intention to expand
its presence in the diamond industry.  The industry is presently undergoing
a period of consolidation and, by increasing our ownership in Ekati TM, BHP
has the opportunity to extract maximum value from this asset."

The offer price represents a premium of 23 per cent on the Class A Shares
and a premium of 15 per cent on the Class B Shares based on their trading
prices immediately prior to the 17 October, 2000 auction announcement by Dia

The offer will be mailed to all registered holders of Class A Shares and
Class B Shares shortly and is conditional on BHP acquiring at least 75 per
cent of each class on a fully diluted basis.  The offer is subject to some
regulatory approvals, which are expected to be forthcoming.
