Really solid update from Tertiary today on their Mushima North project in Zambia. The company’s clearly moving fast and the results from Target A1 are genuinely encouraging.
They’ve hit broad, shallow zones of mineralisation right from surface, including:
• 58m @ 49 g/t silver, 0.26% copper, 0.16% zinc (≈0.94% CuEq) from 8m
• 73m @ 32 g/t silver, 0.16% copper, 0.24% zinc (≈0.64% CuEq) from 11m
• With a high-grade section of 9m @ 124 g/t silver & 0.73% copper (≈2.4% CuEq) – and that hole actually ended in mineralisation.
The zone is around 450m x 400m, starts from as little as 2m depth, and remains open in all directions. They’re also seeing traces of antimony, gallium and bismuth, which adds a bit of critical-minerals interest.
Tertiary’s now doing mineralogy and gold assays to see how the metals are linked, and they’ve brought in consultants to check if there’s already enough data for a JORC Exploration Target. If so, that could be a major step toward a first resource.
Next phase will focus on drilling outwards and deeper to prove continuity and build scale – the aim being to reach maiden MRE territory if the results hold up.
And it’s not just A1: there are several big untested targets nearby –
• A2: copper-in-soil anomaly about 6km SW,
• B1/B2/B3: strong EM and soil anomalies 4–7km NW,
• C1: historic hole with 33m @ 0.24% Cu that ended in mineralisation right over a BHP-defined IOCG gravity target.
Put together, this could easily be a district-scale IOCG system, only 28km from the old Kalengwa copper-silver mine (5.2% Cu, 40 g/t Ag).
If the upcoming gold assays, metallurgical work and exploration target come back well, TYM might finally have something serious
