A 1,500m reverse circulation (RC) drilling program is testing advanced targets at Cosmo’s Mt Venn and Eastern Mafic Projects in the Yamarna district of Western Australia.

At Mt Venn, the program will chase up high-grade zones and extensions to thick copper mineralisation discovered back in late 2021, where hits included up to 46m at 0.80% copper from 141m including 12m at 1.26% copper from 155m.

Mobilisation of a down-hole electromagnetic (DHEM) survey crew has begun surveying drill holes at Eastern Mafic, around 7km to the east of Mt Venn.

The DHEM crew will then survey four holes at Winchester, about 50km north of Mt Venn, that were drilled in 2020 to test EM targets.

Drill-ready targets

Cosmo Metals (ASX:CMO) Managing Director James Merrillees says the team is excited to be embarking on a new RC program designed to follow-up on high potential drilling and geophysical targets at Mt Venn.

“With a geophysical crew on site, we eagerly anticipate working up drill-ready targets at Mt Venn, Eastern Mafic and Winchester.

“We’re looking forward to delivering a raft of exciting exploration news flow in the second half of the year from our work programs.”

Opportunity for a meaningful discovery

The Winchester Project (E38/2129) is owned in joint venture with Ausgold (ASX:AUC) with Cosmo currently holding a 75% interest.

With numerous untested targets, and elevated PGE’s and gold in historical drilling as compared to the Mt Venn and Eastern Mafic projects, the project has seen no on-ground work since 2020 when drilling by Great Boulder (ASX:GBR) intersected several zones of mineralisation.

These zones, which remain open, include 4.4m at 0.8% copper, 4.7 g/t silver, 0.08% nickel and 0.01% cobalt from 201.86m.

CMO believes Winchester represents an excellent opportunity for a meaningful discovery in the company’s Yamarna Project.
