Tertiary Minerals plc (AIM: TYM) has reported more results from Phase 2 drilling at its Mushima North Project in Zambia, including its highest silver and copper grades so far.
Hole 25TMNAC-038 intersected 58 metres at 49 g/t silver, 0.26% copper and 0.16% zinc (72 g/t silver equivalent or 0.94% copper equivalent) from 8 metres. This included 9 metres at 124 g/t silver and 0.73% copper (185 g/t silver equivalent or 2.40% copper equivalent) from 57 metres, with mineralisation continuing at the end of the hole.
The drilled footprint has now been extended 100 metres north, covering an area of 450m by 400m, and remains open in several directions.
Highlights:
Ø Highest-grade silver/copper mineralisation intersection to date on the project:
· 58m at 49 g/t Ag, 0.26% Cu and 0.16% Zn (72 g/t Ag equivalent or 0.94% copper equivalent) from 8m downhole (hole 25TMNAC-038).
§ Including: 20m at 86 g/t Ag, 0.44% Cu and 0.24% Zn from 46m downhole.
§ And: 9m at 124 g/t Ag, 0.73% Cu and 0.25% Zn (185 g/t Ag equivalent or 2.40% copper equivalent) from 57m downhole. The hole ended in mineralisation.
Ø Results include high-grade copper mineralisation (9m at 2.40% copper equivalent) and suggest the presence of a previously unknown zone of high-grade copper mineralisation, which is open to the north.
Ø Mineralisation footprint extended by a further 100m to the north, now over a 450 by up to 400m area, and remains open to the north/northwest, south/southeast and at depth.
Richard Belcher, Managing Director of Tertiary Minerals plc, commented:
“We are thrilled to report not only our best intersection of silver mineralisation so far on this project, but also higher-grade copper mineralisation with individual metre samples returning grades of up to 1.68% copper. Hole 25TMNAC-038 returned 58m at 72 g/t silver equivalent (or 0.94% copper equivalent) from near surface. This hole also included our best copper intersection so far at 9m at 2.40% copper equivalent (185 g/t Ag silver equivalent) from 57m downhole, with the hole ending in mineralisation. Significantly, the high copper and silver values are from the northern most drill line, so the mineralisation remains open to the north and at depth.
“These additional results have also extended the surface footprint of the mineralisation to the north by approximately 100m. The mineralisation footprint is now approximately 450m by 400m within a northwest-southeast orientation and remains open to the north/northwest, south/southeast and at depth. These results further support our bulk tonnage, open pit silver exploration model as well as the additional potential for copper and adds further credence to the significance of this discovery for the Company.”
