Great Panther Provides Update on Tucano Gold MineCanada NewsWireVANCOUVER, May 14, 2019TSX: GPR | NYSE American: GPLVANCOUVER, May 14, 2019 /CNW/ - GREAT PANTHER MINING LIMITED (TSX: GPR; NYSE American: GPL) ("Great Panther", the "Company") is pleased to announce the successful commissioning of the supplemental modular liquid oxygen supply system ("Supplemental Oxygen") at the Tucano Gold Mine in Brazil ("Tucano"), which is designed to allow for the processing of the higher-grade sulphide ore produced by the mine and achieve designed and budgeted gold recoveries.The Supplemental Oxygen has been operational since start of May and has successfully processed sulfide ore at grades as high as 2 grams per tonne gold ("g/t Au") with high (94%) recoveries. The following provides a summary of the plant performance. Tucano Plant Report Summary(1) Q1 – 2019April, 2019May 1 – 13, 2019Dry ore milled (tonnes)747,200254,70083,201Feed grade (g/t Au)1.110.981.75Gold recovery (%)88.087.694.5Gold recovered (oz)23,4707,0204,429(1) Full first quarter summary from January 1 – March 31, 2019. Prior to the installation of the Supplemental Oxygen, Tucano was limited to processing primarily lower grade oxide material. Preliminary results demonstrate the ability to process Tucano's highest-grade sulfide materials with recovery rates exceeding planned rates. James Bannantine, President and CEO stated: "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."Processing plant availability and utilization for the period of May 1st to 13th was lower than designed capacity levels to facilitate testing and optimization during the commissioning of the Supplemental Oxygen, and due to higher than planned maintenance of the SAG mill. As a reference, gold produced from May 1st to May 13th was based on plant utilization of 73%. Gold production is expected to increase during the month of May as the SAG mill availability improves and the mill is turned back up to full capacity. The addition of the Supplemental Oxygen completes the functionality of the recent plant upgrade of ball mill, thickener, additional CIL tankage and oxygen supply to handle the mine's sulfide production going forward.
