Great Panther Mining (TSE:GPR) (NYSEAMERICAN:GPL) can now process higher grade ore due to a plant upgrade at its Tucano gold mine in Brazil ,an asset that came through its now-completed acquisition of Beadell Resources.
The plant has now seen the successful commissioning of the supplemental liquid oxygen supply system, which will allow for the processing of the higher-grade sulphide ore and achieve designed and budgeted gold recoveries, the metals miner said.
The system has been operational since the start of May and has successfully processed sulfide ore at grades as high as 2 g/t (grams per ton) gold with high (94%) recoveries.
"We are very happy to successfully conclude what was probably the most important single element in the Tucano turnaround, which is ongoing and progressing well. This is also a critical accomplishment for the new Great Panther Mining team, as we integrate our teams into one," said CEO James Bannantine.
By way of comparison, Great Panther revealed that from May 1 to May 13, it milled 83,201 dry tonnes, at a feed grade of 1.75 g/t of gold, recovering 4,429 ounces of the yellow metal, a 94.5% recovery rate.
In April this year, Great Panther milled 254,700 tonnes, at a feed grade of 0.98 g/t, recovering 7,020 ounces, a recovery rate of 87.6%.
Gold production expected to increase
Gold production is expected to increase during the month of May as mill availability improves and the mill is turned back to full capacity.
The addition of the oxygen system completes the recent plant upgrade of ball mill, thickener, additional CIL tankage and oxygen supply to handle the mine's future sulfide production.
Great Panther operates three mines, including Tucano in Amapá State, Brazil, and two primary silver mines in Mexico: the Guanajuato Mine Complex and the Topia Mine.
It is also evaluating the restart of the Coricancha project in Peru and expects to make a decision on whether or not to restart the project in June this year.
