Tertiary Minerals PLC 26 January 2000 TERTIARY MINERALS PLC TERTIARY ADDS TO ITS SWEDISH PORTFOLIO WITH ZINC PROJECT IN HISTORIC BERGSLAGEN MINING DISTRICT Application Covers 9 Sq Kms - First New Prospect Since Aim Listing Previous Assays Showed Up To 18.8p.c Zinc Drilling Programme Planned For 'High Priority' Windfall Project Tertiary Minerals plc, which is focusing its efforts on base and precious metals exploration in Sweden, has made the first addition to its portfolio since it listed on London's Alternative Investment Market (Aim) in September, 1999. The company, through its wholly owned subsidiary Tertiary Gold Ltd, has applied for an exploration permit covering a 9 sq. km area surrounding old mine workings at Djuragruven in the north east part of the historic Bergslagen mining district of south- central Sweden. Surface sampling at Djuragruven in the 1980s by SGAB, a former state owned prospecting company, returned assays up to 18.8p.c. zinc. The dimensions of the mineralisation are not clear, however, because of the low amount of surface exposure in the area. Djuragruven is located some 120km west of Tertiary's Windfall zinc-silver project where the company's previous drilling has defined two zones of open-ended, zinc-silver rich mineralisation at Vindfall and Sortarnan over 400m and 100m respectively. Drill intersections up to 7.7m at 10.9p.c. zinc and 91g/t silver were obtained at shallow depths in the company's latest drilling programme. Tertiary says its objective is to evaluate new projects such as Djuragruven quickly, alongside exploration of its core portfolio - at present six projects in Sweden. Windfall remains a high priority project for the company. A geophysical test programme will begin there on January 31, 2000, over the known mineralisation to see if it has a clearly identifiable geophysical response which would allow this exploration technique to be used to 'map out' any potential extensions to the know mineralisation and to identify additional drilling targets. A new drilling programme is planned to start at Windfall in early spring this year.
