TSX: GPR | NYSE American: GPL

VANCOUVER, BC, July 9, 2020 /PRNewswire/ - Great Panther Mining Limited (TSX: GPR) (NYSE-A: GPL) ("Great Panther" or "the Company") announces second quarter (Q2) 2020 production results from its three 100% owned mines: Tucano in Brazil, and Topia and the Guanajuato Mine Complex (GMC) in Mexico.  Consolidated quarterly production totalled 38,540 gold equivalent ounces (Au eq oz) and included record monthly production in June at Tucano since its acquisition in early 2019.

Q2 2020 Highlights

• Produced 38,540 Au eq oz on a consolidated basis, including 36,356 gold ounces (Au oz) and 142,457 silver ounces (Ag oz)
• Produced 35,421 Au oz at Tucano, 35% higher than Q1 2020 and 18% higher than Q2 2019
• In June, set new Tucano monthly production record of 15,389 Au oz since acquisition
• Recommenced production at Topia and GMC following COVID-19 related shutdown in April and May
• Strengthened the balance sheet with a US$16 million bought deal financing, adding to the March 31, 2020 cash position of US$39 million

Great Panther President and CEO Rob Henderson commented, "In Brazil, Tucano outperformed this quarter despite the challenges of COVID-19, and in Mexico, Topia and GMC have returned to stable production following the lifting of government mandated restrictions on mining.  I would like to thank our teams for delivering these strong results while prioritizing the safety and health of our people and communities and adjusting to these unprecedented times."

On a consolidated basis, Great Panther expects to produce 146,000-158,000 Au eq oz in 2020.  This reflects the addition of 2020 production guidance for Topia which is being provided for the first time.  Details are included in the 2020 Guidance section near the end of this news release.

Q2 2020 production results are preliminary and subject to adjustment with Great Panther's Q2 2020 earnings results, scheduled for release after the close of markets on August 5, 2020.  A conference call will follow on August 6, 2020.

COVID-19 Response

Great Panther has developed and implemented significant COVID-19 prevention, monitoring and response plans following the guidelines of the World Health Organization and the regulatory agencies of each country in which it operates to ensure a safe work environment.  Protocols include mandatory medical screening and testing on arrival at site, mandatory medical leave, training sessions on health awareness and new health and safety protocols, physical distancing and increased sanitation measures, and updated operating procedures.  Specific areas have been prepared for the isolation, testing and care of employees showing COVID-19 symptoms.  All confirmed cases of COVID-19 are in isolation and being monitored by Company health professionals with regular reports to health authorities.

Q2 2020 Consolidated Operating Results

Silver production was impacted by government-imposed restrictions on non-essential business operations in Mexico in response to COVID-19, which limited mining activities in the country for most of April and May.  Great Panther's mining operations in Mexico recommenced operations in June following the lifting of restrictions.

Tucano

Tucano produced 35,421 Au oz in Q2 2020, an increase of 18% compared to Q2 2019 due to increased ore processing rates, higher gold grades and higher recoveries.  Despite particularly adverse weather conditions in Q2 2020 and the implementation of measures to manage COVID-19, Tucano also achieved a 21% increase in material mined relative to Q2 2019, benefitting from the implementation of operational improvements.  Notably, June 2020 production of 15,389 Au oz set a new monthly production record since the time of acquisition in March 2019.  The 35% increase in Q2 2020 production relative to Q1 2020 was primarily due to higher gold grades.

Mining activities continue uninterrupted at Tucano at this time as the state of Amapá in Brazil has not introduced measures to restrict mining activities in response to COVID-19.  Separately, Great Panther has implemented numerous health and safety measures to protect against the spread of the virus, working closely with local health and labour authorities to protect its people and local communities.  The Company continues to monitor the situation closely to be in a state of preparedness.

The investigation following the geotechnical incident which suspended mining at Tucano's Urucum Central South pit in Q4 2019 is ongoing under the supervision of independent engineering consultants Knight Piesold.

Mexico Operations

Great Panther's Mexican operations produced 3,122 Au eq oz in Q2 2020 or 280,911 Ag eq oz.  Mining operations in Mexico were suspended for the months of April and May following a directive of the Mexican Federal Government to mitigate the spread of COVID-19.  Production resumed in early June, following a government order adding mining to the list of essential services.

Topia

Topia produced 146,208 Ag eq oz in Q2 2020, a decrease of 65% compared to the same period in 2019 due to the COVID-19 related shutdown in the months of April and May.

As disclosed on March 9, 2020, Great Panther ceased depositing tailings on the Topia Phase II tailings storage facility ("TSF") following a recommendation from the Company's independent tailings management and geotechnical consultants.

During the suspension of non-essential activities due to COVID-19, Great Panther continued monitoring the conditions on Phase II and installed additional geotechnical instrumentation. In addition, tests were carried out to determine the state of the tailings in Phase I.  Extensive work has been carried out to identify and reduce the flow of water into the base of the TSF.  Monitoring indicates it is safe to return to stacking in Phase II, subject to receipt of a final report from consultants who will also provide a revised stacking plan.  The Company has now also received the required government approvals and a permit to start stacking on Phase III, which becomes available after constructing gabion walls and erosion controls around the base of the facility.  In the meantime, there is sufficient capacity at the temporary tailings storage location to continue operations.

Guanajuato Mine Complex

GMC produced 134,703 Ag eq oz in Q2 2020, a decrease of 65% compared to the same period in 2019 due to the COVID-19 related shutdown in the months of April and May.
