Cornish Metals constrains Wide Formation mineralisation
South Crofty developer Cornish Metals has announced final drilling results from its exploration of the Wide Formation adjacent to the existing South Crofty mine in Cornwall.
The 14 hole, 8,993 m drilling programme successfully tested the geometry and continuity of tin mineralisation within a 2,500 by 800 m extent. The drilling also intersected mineralisation discovered earlier in 2024 at the Great Flat Lode and the Great Flat Lode Splay.
The company said the results have increased overall confidence in its exploration model and confirm the potential of systematic exploration drilling to make new discoveries and expand the South Crofty mineral resource.
Cornish Metals highlighted intercepts of 10.55 m at 0.19% Sn including 1.49 m at 0.72% within the Wide Formation, as well as intercepts of 1.56 m at 0.76% Sn, 2.07 m at 0.85% Sn, and 1.96 m at 0.66% Sn within high-grade ‘dropper’ zones between the Great Flat Lode and Wide Formation.
Additionally, the drilling intercepted copper within a new structure for 2.11 m at 5.48% Cu and 0.58% Sn.
Cornish Metals Interim CEO and Director Ken Armstrong commented the drilling has “validated the Wide Formation as a new, large-scale, tin-bearing exploration target that is potentially accessible from the underground workings at South Crofty.” Continuing, he said the new discovery of polymetallic tin and copper “further demonstrates the exploration potential of the South Crofty area”.
In July, Cornish Metals announced the completion of the sale of its royalties at the Mactung and Cantung tungsten projects in Canada for a total of US$4.5 million, and the sale of its Nickel King project in June for approximately US$5.9 million. The company said it would use the proceeds of these sales to continue development of South Crofty.
We are pleased to see positive exploratory drilling results from Cornish Metals, and we look forward to seeing further work to potentially expand the South Crofty mineral resource, which is the world’s highest-grade tin resource not currently in production.
