Great Panther Announces Agreement with Nyrstar to Defer Coricancha Bond Requirements

TSX: GPR | NYSE American: GPL

VANCOUVER, BC, June 29, 2020 /PRNewswire/ - Great Panther Mining Limited (TSX: GPR); (NYSE-A: GPL) ("Great Panther" or "the Company") announces an agreement with Nyrstar International B.V. and Nyrstar Netherlands (Holdings) B.V. (together, "Nyrstar") and NN2 Newco Limited, the parent of the Nyrstar entities, to amend certain agreements (the "Amending Agreements") in respect of the Company's remediation obligations in connection with Great Panther's 2017 acquisition of the Coricancha mine ("Coricancha") from Nyrstar. The amended agreements include the Share Purchase Agreement under which the Company purchased Coricancha from Nyrstar and the related agreement for Coricancha under which Nyrstar agreed to fund a portion of the bond to secure remediation costs for Coricancha in future in respect of a permanent closure of the mine.

Under the Amending Agreements, Nyrstar has agreed to extend its remediation bond obligations beyond the original June 30, 2020 expiry date. The Amending Agreements provide that Nyrstar will maintain a $7.0 million bond until June 30, 2021 and $6.5 million for the following year, effectively deferring Great Panther's funding requirements for these amounts until June 30, 2022.

"We are very pleased with this agreement with Nyrstar that reduces our short-term funding requirements and improves our ability to advance Coricancha in a manner that meets our mutual interests," stated Rob Henderson, President and CEO. "This latest agreement highlights Great Panther's commitment to realizing Coricancha's significant potential, particularly with the recent strength in gold and silver prices."

The Amending Agreements provide that Great Panther will use commercially reasonable efforts to seek an amendment to a closure plan for certain legacy tailings facilities which Nyrstar is obligated to fund. The objective of the amendment is to seek a technically superior closure plan for approval by the Ministerio de Energía y Minas de Perú with potentially lower costs. In addition, Great Panther has agreed to pay interest on the bond amounts Nyrstar has agreed to continue to fund at an annual rate of 3-month USD LIBOR plus 5%, and to defer any relocation of the legacy tailings until an agreement on a modified closure plan is achieved or there is a legal requirement to move the tailings. The Amending Agreements also provide Nyrstar with certain offer rights for Coricancha concentrates which are secondary to those of a third party. The Amending Agreements do not impact on the maximum reclamation obligation that Nyrstar is obligated to fund under the Share Purchase Agreement.
