Tertiary Minerals PLC (AIM:TYM, OTC:TTIRF) has released latest exploration results from Target A1 at its Mushima North project in Zambia, where it has now extended the deposit.
The polymetallic silver-copper-zinc prospect lies 28 kilometres east of the historic Kalengwa copper-silver mine, and recent drilling has intersected broad mineralised zones, including 58 metres at 49 grams per tonne silver, 0.26% copper and 0.16% zinc from 8 metres downhole.
The mineralisation extends to a depth of 84 metres and remains open in multiple directions. Elevated levels of bismuth, antimony and gallium were also reported.
Mushima North now has a surface footprint of approximately 450x400 metres and remains open to the north/northwest, to the south/southeast and at depth.
"The silver grades and widths intersected to date (supported by copper and zinc values) are comparable in terms of silver equivalent grades to several polymetallic, open-pit silver deposits currently being explored and mined elsewhere in the world and for which Mineral Resources estimates have been reported," said managing director Richard Belcher.
"We therefore believe this could represent a significant discovery for the company."
Belcher added: "We hope to be able to fast-track the project along the valuation pipeline towards a maiden mineral resource estimation in the next 12 months."
