Meeka Metals has secured a greater-capacity ball mill than envisaged in its definitive feasibility study in May for its Murchison gold project in WA, paving the way for significantly enhanced economies of scale. The company says the $318,000 purchase reduces its DFS mill capex by 75 per cent, lifts processing capacity by 30 per cent to 640,000 tonnes per annum and increases ore processing options.
