RELEASED ON BEHALF OF TERTIARY MINERALS PLC: 21 February 2002 TERTIARY TOPS UP ITS TREASURY AHEAD OF TANTALUM AND PLATINUM DRILLING PROGRAMMES · Company Raises £356,000 At 25p Per Share Tertiary Minerals Limited, the AIM listed explorer which this month was awarded rights to the world's largest known tantalum deposit in Saudi Arabia, has made a small placement of new shares at 25p each to raise £356,000 bringing its cash position to over £500,000. The company is due to start drilling programmes in March at its Rosendal tantalum deposit in Finland and in April at its promising Norwegian platinum prospects. Tertiary's chairman, Mr. Patrick Cheetham said: "The small fund raising was designed to keep down dilution for existing shareholders to the minimum and yet fund all our requirements until warrants become exercisable in November (at 12p per share). That should bring in another £1.5m of funding towards our bigger goals." Further information: Patrick Cheetham, Tertiary Minerals. Tel: 01625-626203 Ron Marshman, City of London PR. Tel: 020-7628-5518
