True North Copper (ASX:TNC) announces an updated mineral resource estimate (MRE) for its Wynberg Gold-Copper Project, located on a granted mining lease 25km east of Cloncurry.
The company has expanded the combined measured, indicated, and inferred resource to 1 million tonnes (Mt) at 1.86 grams per tonne gold (Au) and 0.25% copper (Cu).
The updated JORC resource contains 61,000oz Au and 3,000 tonnes Cu at a 0.40g/t Au cutoff grade. The estimate integrates recent drilling and refined geological modelling, increasing confidence in the deposit.
True North says the update boosts its total Cloncurry Copper Project resource base to 17.75Mt @ 0.73% Cu and 0.26g/t Au, containing 128,000 tonnes Cu and 152,000oz Au.
The company adds it also underpins the assumptions outlined in the Wynberg Scoping Study.
Managing Director Andrew Mooney says the updated MRE demonstrates that Wynberg is “not solely a gold project, but a gold-copper system with potential for further growth and development flexibility”.
Wynberg hosts 416,000 tonnes @ 2.12g/t Au and 0.41% Cu in measured resources; 568,000 tonnes @ 1.69g/t Au and 0.14% Cu in indicated resources; and 34,000 tonnes @ 1.42g/t Au and 0.09% Cu inferred resources.
Notable copper intercepts from recent drilling include 27.82m @ 1.2g/t Au and 1.0% Cu from 6.18m, including 20.04m @ 1.6g/t Au and 1.33% Cu from 9.98m.
Additional intercepts returned 46m @ 1.8g/t Au and 0.42% Cu from 8m, and 34.4m @ 3.9g/t Au and 0.44% Cu from 20m, including 9.1m @ 7.9g/t Au and 1.06% Cu from 32.4m.
True North intends to undertake field rock chip and soil sampling ahead of drilling growth targets at Burnt Ute and strike extensions at Wynberg.
True North Copper is a mineral explorer focused on copper, silver, gold, and cobalt in Queensland’s Mt Isa region.
