Cornish Metals Inc (AIM:CUSN, TSX-V:CUSN, OTC:SBWFF) said multiple zones of mineralisation were intersected from nine holes drilled to test the Trenares Lode target within the United Downs project in Cornwall, England.
"The Trenares Target drill programme has been successful in demonstrating the presence of multiple zones of mineralisation in an area of the United Downs project that is underexplored, has never been mined and represents a compelling exploration target,” said chief executive Richard Williams.
Highlights from the assay results include 2.42 metres (m) grading 2.88% tin and 1.43% zinc; 3.34m grading 2.48% zinc and 22 grammes per tonne (g/t) silver; 0.90m at 10.30% zinc and 18 g/t silver; 1.52m at 0.72% tin, 1.69% zinc and 14 g/t silver; and 0.62m grading 1.46% tin, 5.23% zinc and 18 g/t silver.
“The presence of high-grade tin and zinc warrants further follow-up exploration,” said Williams. “Once we are in receipt of all remaining drill programme assays, we can evaluate the priority targets for follow up work."
The drilling programme at United Downs has been completed, although results are pending for a further five holes drilled into the Mount Wellington, UD Lode, and United Mine targets. In addition, results from eight holes drilled at the Carn Brea South Target, located about 2km southeast of the South Crofty mine site, will be released in due course, the company said.
The United Downs project covers, or is located immediately adjacent to, four former copper and tin producing mines and is situated about 8km east of South Crofty, the company’s high-grade, underground tin project.
The drill rig has now been moved to South Crofty to start work on an 8,000-12,000m drill programme designed to collect samples for metallurgical testwork as part of a feasibility study and subsequent construction decision for the South Crofty mine.
The drilling programme will involve three rigs testing the eastern, central, and western part of the mine complex. The other two drill rigs are expected to arrive at South Crofty over the next four to six weeks.
The South Crofty project covers the former producing South Crofty tin mine which closed in 1998 following more than 400 years of continuous production.
