Cornish Metals Inc said it had intersected multiple high grade copper-tin-zinc mineralised zones based on the remaining results from Phase I drilling at its United Downs project in Cornwall.
TARGETS
The results include those from the Mount Wellington and United Mines targets within the project which lies some eight kilometres east of the South Crofty tin project.
The Canadian company added that all four of the remaining drill holes had intersected multiple mineralised zones.
DRILLING
Cornish Metals completed two drill holes (MW22_001 and MW22_002), totalling 1,334 metres, at the Mount Wellington target.
The company tested the down dip extensions of both Mount Wellington mine (tin-zinc) and United Mines (copper-tin-zinc-silver).
Two drill holes (UD22_01 and UD22_01A), totalling 1010.61m, in the central part of the United Downs project, tested the down dip extension of United Mines.
RESULTS
MW22_001 intersected several high-grade zinc zones including:
2.05m grading 6.05% zinc from 87.03m;
4.25m grading 5.51% zinc from 249.40m, and;
0.80m grading 6.48% zinc from 362.53m.
MW22_002 intersected several polymetallic zones, including:
1.49m grading 6.17% copper, and 67g/t silver from 326.00m;
4.89m grading 2.21% copper, and 19g/t silver from 548.36m;
1.66m grading 1.09% tin from 560.61m, and;
2.42m grading 3.70% tin, and 9.09% zinc from 649.41m.
MINERAL RESOURCE
“The high-grade zinc intersections in MW22_001 require further work to determine continuity along strike and to depth to establish the mineral resource potential,” added the company in a statement.
“High grade tin intersects were encountered in UD22_01 and UD22_01A, confirming a potential transition from high grade copper to high grade tin at depth, similar to the mineralisation transition seen at South Crofty Mine.
“High-grade copper and tin intersections beneath United Mines have now been observed over a strike length of approximately 1,350m and the zone is open along strike and to depth.”
High-grade tin intersects previously reported support the belief that tin grades increased with depth, similar to the mineralisation transition seen at South Crofty, said the company.
Cornish Metals is considering its next steps for United Downs.
