Advancement Of The High Grade South Crofty Underground Project
VANCOUVER - Cornish Metals Inc. reported on advancing its high-grade South Crofty underground tin project through to delivery of a Feasibility Study, as well as exploring its additional mineral rights located in Cornwall, SW England. It has commenced a minimum 8,000 meter drill program at South Crofty. The program is designed to collect samples for metallurgical testwork as part of the Feasibility Study.
Richard Williams, CEO, said, “This drill program allows us to accelerate the South Crofty Feasibility Study in advance of dewatering the mine and will provide key information for the mineral processing flowsheet, especially the amenability of the mineralized zones to ore sorting which, if successful, will present an opportunity to deliver higher grade feed and reduce the size of a process plant.”
The geology at South Crofty comprises metasediments (locally termed “killas”) overlying an intrusive granite body. The killas typically hosts vein structures (“lodes”) containing polymetallic copper – tin – zinc mineralization, whereas the underlying granite hosts lodes that are predominantly tin only. The granite hosted tin mineralization (“Lower Mine”) is the focus of ongoing work at South Crofty.
