Great Panther Intersects New High-grade Mineralization at Tucano; Appoints Vice President Exploration
Vancouver – June 23, 2020 – Great Panther Mining Limited (TSX: GPR. NYSE-A: GPL) (“Great Panther” or “the Company”) announces initial drill results from the 2020 drill program at its wholly owned Tucano gold mine in Brazil. These results are part of an ongoing 55,000 metre, $6.6 million resource definition drill program focused on both near-mine and regional targets. To date, 12,000 metres of drilling have been completed, including 6,000 metres of near-mine diamond and reverse circulation drilling at the Tapereba (TAP) AB1 and AB3 open pits. The ongoing drilling is being conducted with three rigs and results will be incorporated into an updated Resource and Reserve statement due for release in fourth quarter of 2020. Drilling rates are expected to advance as Tucano enters the dry season in July.
Highlights of the near-mine drill program include intervals of 29.4 metres grading 15.99 grams per tonne gold (g/t Au) in hole DD018 and 16.7 metres grading 10.96 g/t Au in hole DD009, as outlined in Table 1. A full table of all significant intercepts drilled to date can be found on the Company’s website at www.greatpanther.com/operations/operations-overview/.

Notes:
| · | DD = diamond drilling; RC = reverse circulation |
| · | Highlight drill results are +25 gram*metre intervals intersected in drilling this year. |
| · | True widths are estimates based on current geologic knowledge but may vary after resource modelling. Certain intersections are necessarily oblique to the mineralized zones due to access constraints due to topography and pit development. |
Great Panther President and CEO Rob Henderson commented: “The 2020 exploration program at Tucano is a top priority. The focus to date has been on converting inferred resources to measured and indicated and we are encouraged by the number of significant zones that have exceeded expectations either in grade, width, or both. We are working to capitalize on Tucano’s significant exploration potential, both in the existing pits and on regional targets in this largely unexplored area.”
Tapereba represents two-thirds of the seven-kilometre Tucano mine trend, with TAP AB1 and AB3 located toward the southern end (see Figure 1). They are the largest and deepest pits on the trend, containing an average resource grade of 2.33 g/t Au (refer to the Tucano Technical Report dated December 31, 2019 and released on March 25, 2020, available on the Company’s website at www.greatpanther.com).

Appointment of Vice President Exploration
Great Panther also announces the appointment of Nick Winer to the position of Vice President Exploration. Mr. Winer has extensive international experience in both major and junior mining companies, largely focused on Latin America where he has been involved in the discovery of world-class gold and base metal deposits. He was involved with the initial resource/reserve definition program at Tucano from 1996 to 2000, initially as Exploration Manager for BHP Minerals and later as Exploration Manager for AngloGold Ashanti.
Mr. Winer commented: "I am excited by the opportunity to be involved with Great Panther’s exploration program at Tucano. The region offers significant upside potential as it has been largely unexplored. Great Panther is demonstrating that they mean to change this."
Prior to joining Great Panther, Mr. Winer was Vice President Exploration for AngloGold in Colombia and later for all of South America. He was Chief Operating Officer of Horizonte Minerals and has held Exploration Manager positions in Brazil for BHP and AngloGold, and senior exploration positions for BHP in Chile and Ghana.
Mr. Winer’s focus will be on advancing Great Panther’s exploration programs in Brazil, Mexico and Peru. He holds a BSc in Geology and Geophysics from Macquarie University in Sydney, Australia, and is a member of AusIMM. He currently resides in Brazil.
Qualified Person and QA/QC
The technical information contained in this news release has been reviewed and approved by Nicholas Winer, Member of the AusIMM, a Qualified Person (QP) for the purposes of National Instrument (NI) 43-101. Drill program design, implementation, and interpretation of results were performed by Great Panther geologists and overseen by the QP. A Quality Assurance/Quality Control (QA/QC) program consistent with NI 43-101 and industry best practices was carried out by the Company regarding drill core logging and sampling. The QA/QC program included the regular insertion of standards, blanks and duplicates into the sample batches, as well as further umpire sampling by an independent certified laboratory.
The majority of results were produced by the Tucano laboratory, which carries out preparation on all samples at Tucano and has independent sample preparation lines for grade control and resource definition. Initial assays are performed by the Tucano laboratory and all samples to be included in the resource definition model are forwarded to the accredited SGS laboratory in Belo Horizonte, Brazil.
Great Panther uses industry standard QA/QC practices for all sample batches, including those to be assayed by the Tucano and certified SGS laboratories. These QA/QC procedures and associated assay results were independently reviewed and approved by RPA as part of the NI 43-101 Tucano Technical Report dated December 31, 2019 and released on March 25, 2020, available on the Company’s website at www.greatpanther.com).
