NYSE American: GPL | TSX: GPR

GREAT PANTHER MINING LIMITED (NYSE American: GPL; TSX: GPR) ("Great Panther", the "Company") announces that its wholly owned subsidiary, Minera Mexicana el Rosario, S.A. de C.V. ("MMR"), has entered into a US$10 million concentrate prepayment agreement with the IXM Group ("IXM"), one of the world's largest physical metal traders, headquartered in Geneva, Switzerland. MMR wholly owns and operates the Company's Mexican mining operations.

In consideration of an off-take agreement with a subsidiary of IXM at market-based commercial terms for 100% of the gold-silver concentrates produced from the Guanajuato Mine Complex ("GMC") in 2020 and 2021, IXM has agreed to advance a US$10 million prepayment to MMR on December 30, 2019. The prepayment will be repaid on December 31, 2020 and will bear interest at an annual rate of 3-month USD LIBOR plus 5%. Great Panther has issued a guarantee to IXM with respect to the prepayment. There is no hedging of the price of gold or silver associated with the off-take or prepayment agreement.

"We are pleased to be partnering with IXM in Mexico for our GMC concentrates over the next two years," stated Jeffrey Mason, Interim President and CEO. "Securing the sale of this off-take at competitive market terms, while strengthening our balance sheet with US$10 million at an attractive cost of capital, positions us well to achieve our strategic objectives as we move into 2020."
