Work is underway to upgrade the pilot plant to 65 tonnes per month of tin concentrate.
AfriTin will use knowledge gained from the pilot operation as part of a bankable feasibility study after which plant production will ramp up to up to 5,000 tons per year.
Alongside the pilot operation, AfriTin will carry out a detailed exploration programme and map out a long-term mine plan.
The company raised £6mln in May to fund the exploration plans and work on the bankable feasibility study.
Losses in the year to February were £1.53mln.
