VANCOUVER, BC, Dec. 30, 2021 /CNW/ - Great Panther Mining Limited (TSX: GPR) (NYSE-A: GPL) ("Great Panther" or the "Company"), a growing gold and silver producer focused on the Americas, announces that it intends to file a defense to three Notices of Infraction (the "Notices") that were delivered by the Amapa State Environmental Agency (the "Agency") to its Brazilian subsidiary, Mina Tucano Ltda. ("Mina Tucano"), on December 21, 2021. The Notices were issued in connection with the Agency's investigation of a fish mortality event at Areia and Silvestre Creeks, and its assertion that the incident was caused by a leak in a reclaimed water pipe at the Mina Tucano mine site.

Mina Tucano is actively investigating whether there could be any connection between the fish mortality event and the Tucano mine site.  Based on its initial investigation, including independent reports on fish toxicology and water quality received by Mina Tucano on December 28, 2021, the Company has prepared  a formal defense against the position taken by the Agency. The Notices impose aggregate fines of 50,000,000 Brazilian reals, payable by January 30, 2022.  The Company intends to appeal the amount of the fines and timing of any payment in its defense statements.
