Tertiary starts deeper drilling on promising target at Mushima North
Tertiary Minerals has started with a 1 500 m air core and reverse circulation drilling programme on the Mushima North project, in Zambia.
The drilling is focused on the Target A1 area and will test along strike and downdip continuations of mineralisation.
Drilling of this same target late in 2024 returned drill intersections of 57 m of gold grading 25 g/t, copper grading 0.20% and zinc grading 0.15% from 14 m downhole; and 65 m of gold grading 23 g/t, copper grading 0.14% and zinc grading 0.27% from 69 m downhole.
Target A1 is located 28 km east of the historic Kalengwa copper/silver mine that is currently under development.
Tertiary MD Richard Belcher says the initial 1 274 m drilling programme at Target A1 identified near-surface polymetallic mineralisation over a width of 350 m and downhole intervals of up to 67 m, with many of the holes ending in mineralisation.
The new drill programme has been designed to follow up on these highly encouraging drilling results and will both test the surface footprint of silver and zinc anomalies of a strike extent of 1.6 km and 300 m wide, as well as the downdip potential to a depth of up to 150 m.
Tertiary owns 90% of Copernicus Minerals, which holds 100% of the Mushima North project.
