Great Panther Mining Limited provided an exploration update on its 2019 results and 2020 plans for its two Mexican mining operations: the Topia Mine and the Guanajuato Mine Complex ("GMC"), which includes the Guanajuato Mine and the San Ignacio Mine. GMC - San Ignacio Mine: The 2020 exploration drill program, comprising up to 8,500 meters, will focus on in-fill drilling along the Purisima, Purisima Bo, and Melladito South structures, as well as testing additional exploration targets along the Purisima and a nearby hanging wall structure. Part of these efforts will be focused on testing areas in the historical San Ignacio Mine (Purisima structure) that were previously developed but not exploited. The 2019 drilling program (7,535 metres in 30 holes) successfully tested and in-filled the Nombre de Dios 2, Purisima, Purisima Bo, and Melladito South structures. Development at San Ignacio is moving along the Melladito South vein into the old San Pedro Mine area where the orebody intersects the Purisima veins. This is an area of historical mining where the Company benefits from access in order to plan exploitation of the silver-gold mineralization both on strike and down dip of old workings. The San Ignacio quartz veins are epithermal in nature with economically interesting vertical extents of 100-200 metres. An update on the San Ignacio NI 43-101 Mineral Resource Estimate will be released in the first quarter of 2020. GMC - Guanajuato Mine: At the beginning of 2019, the Company made the decision to halt production at the main Guanajuato mines in order to focus on exploration for higher-grade resources. Three drills completed 8,832 meters in 126 holes, mainly underground, and focused on the Valenciana, Pozos, and Promontorio areas. In addition, the mine exploration team has re-mapped and sampled most accessible areas, including the upper Spanish era workings, and developed multiple new drill targets. Based upon the success of this 2019 program, the Company is working towards the resumption of mining in 2020. The 2020 exploration program, comprising 14,400 meters, will include infill drilling in the Promontorio and Pozos areas, and expand northward to test the north flank of the Cata area and the Valenciana to Guanajuatito area. The continued focus of the program will be on building mineral resources along the Veta Madre structure, a complex multiphase quartz breccia system up to 30 metres across, with economic portions found within the main Veta Madre and along hanging wall and footwall contacts. Great Panther's Guanajuato property covers a 4.2 kilometre strike length of the Veta Madre with mining in steep south plunging zones with vertical aspects of up to 500 metres. An update of the Guanajuato NI 43-101 Mineral Resource Estimate will be released in the first quarter of 2020. Topia Mine: The 2020 exploration drill program will comprise 2,500 metres and focus on building mineral resources along the San Juan, Madre, Hipolito, La Prieta, Cantarranas, La Dura, Union de Pueblo, Higuera, and Oliva veins. The 2019 drilling (5,344 metres in 25 holes) initially tested many of these targets with success as evidenced. The NI 43-101 Mineral Resource Estimate for the Topia Mine will be updated by July 2020. Veins in the Topia District, although narrow, display good continuity and are optimally mined using the resue (modified cut and fill) mining method. The primary veins are polymetallic and epithermal in nature, can be traced 4-5 kilometres across the property and typically have a vertical extent of 100-150 metres. Operations at Topia are currently ongoing in 14 different mines, with ore being trucked to a central, upgraded and modernized processing facility. Lead and zinc concentrates are produced, with most of the silver and gold reporting to the lead concentrate. Exploration drilling at Topia is pragmatically driven, considering logistics, geological potential, costs, and operational priorities. Drill program design, implementation, and interpretation of results were performed by Company 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.
