Tertiary Minerals plc has started to produce a JORC-compliant exploration target for Target A1 prospect at the Mushima North silver-copper-zinc project in Zambia.

Bara Consulting Ltd has been engaged for the work, expected to complete during the first quarter of 2026, following silver analysis results from recent drilling.
Additional mineralogical study results are also due in the coming weeks.
Target A1 is a copper-in-soil anomaly, measuring 3.1 km by 1.7km, where 3.083m drilling to date has confirmed copper, silver and zinc mineralisation over an area 450m by 400m and to a depth from near surface to 84m.
Mineralisation remains open both to the north/northwest, south/southeast and at depth.
Tertiary said it had to pause recent drilling, representing phase III, due to early, heavy rains.
Additional drilling in the north of the target area intersected the “best copper results so far” from a pXRF analyser in the field.
Intersected mineralisation from near surface included 95m at 0.41% copper from 10m downhole.
The results include 47m at 0.58% copper from 58m downhole, 25m at 0.75% copper from 80m, and 8m at 1.13% copper from 89m.
Managing director Richard Belcher added that the A1 exploration target would reveal tonnes and grades and an understanding of its potential.
“This will also provide valuable guidance on the planning of future drilling during the next field season as we work towards our goal of producing a maiden mineral resource estimate by Q4 2026.”
Mushima North lies in the prospective iron-oxide-copper-gold region of Zambia.
