South Crofty critical minerals project.

Project Description
South Crofty is in the lowest quartile of the industry cost curve, ranking among the lowest-cost tin producers.

The proposed mine is based on mined throughput of about 500 000 t/y and processing of about 250 000 t/y following preconcentration at an average tin grade of 1.89%.

Production of tin in concentrate is expected to exceed 49 000 t over the 14-year life-of-mine, averaging about 4 700 t/y in the first five years after ramp-up.

Potential Job Creation
The project is expected to create more than 300 direct jobs, and a further 1 000 indirect jobs.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 6% (real) discount rate, of £237-million and internal rate of return of 23%.

Capital Expenditure
Preproduction capital is estimated at £198-million, with a payback of 3.3 years.

Planned Start/End Date
First tin production is targeted for mid-2028.

Latest Developments
Cornish Metals has developed a drilling programme that, subject to funding, will start with underground development and continue during  production.
