Red River Resources Ltd. on Dec. 20 estimated an increase in the mine life for the West 45 polymetallic massive sulfide deposit, part of the Thalanga zinc project in central Queensland, Australia, to at least 2019.
The company expects the increase after the ore reserve estimate for the deposit was updated to 600,000 tonnes at 11.6% zinc equivalent, from 400,000 million tonnes at 15% zinc equivalent previously.
West 45 is the first deposit to be mined at Thalanga as part of restart operations at the project. Underground mining at the deposit started in April, the company said.
The total ore reserve for the Thalanga operations has increased to 2.1 million tonnes at 11.9% zinc equivalent, and the mineral resource now stands at 2.3 million tonnes at 15.5% zinc equivalent.
