RELEASED ON BEHALF OF TERTIARY MINERALS PLC:

GENERAL CONSENSUS OF IMPROVING OUTLOOK FOR TANTALUM DEMAND SAYS TERTIARY.

  • Company Progressing Its Two-Pronged Strategy For Involvement In Tantalum
  • Assay Results Awaited From Infill Drilling At Rosendal Project
  • Winter Geophysical Programme Upgrades Status Of Gallujavre PGM Prospect

In its interim report for the six months ended March 31, 2002, AIM-listed Tertiary Minerals plc says it is delivering on its two-pronged strategy for involvement in the tantalum business. This comprises the modest-scale Rosendal project in Finland that can be fast-tracked to production, and the huge Ghurayyah project in Saudi Arabia, capable of supplying substantial amounts of tantalum in 3-5 years time when supply shortfalls are predicted.

Furthermore, it believes there is now evidence that the weakness in the tantalum market has tailed off, with several producers recently reporting increasing demand. "It is generally agreed that the outlook for tantalum demand is for continuing long-term growth", Tertiary states.

At Rosendal, assay results are awaited from the infill drilling programme on the main pegmatite dyke in which all of the previously published resources (1.3m tonnes grading 289g/t tantalum pentoxide) are located.

Meanwhile, the programme of metallurgical process-development testwork has commenced at the 385m tonne Ghurayyah project with the objective of evaluating various process technologies for this major tantalum resource to form the basis for a preliminary technical and economic evaluation.

The Finnmark platinum group metals project in northern Norway has now advanced to the drilling stage following a major geophysical exploration programme during the winter which downgraded the Porsvann prospect but upgraded Gallujavre. There, outcropping low-grade nickel-copper mineralisation, with values of 2.5g/t combined platinum, palladium and gold, was discovered last summer in the largest of the ultramafic intrusives known in the Finnmark region.

Exploration of the company's base metal projects has been assigned lower priority, but new drilling targets for zinc have been identified in Sweden.

The Group operating loss for the half-year was £144,555, including £4,213 of bank interest income. At March 31, Tertiary had £458,125 in cash following a placement of 1.42m shares in February at 25p each. At the end of April, Dr Michael Price retired as a non-executive director. He has been replaced by former BHP-Billiton exploration chief executive Mr David Whitehead.
