Great Panther Provides 2020 Exploration Plans for Tucano Gold Mine

NYSE American: GPL  |  TSX: GPR

VANCOUVER , Feb. 6, 2020 /CNW/ - GREAT PANTHER MINING LIMITED (NYSE American: GPL; TSX: GPR) ("Great Panther", or the "Company") is providing an exploration update for its wholly owned Tucano Gold Mine ("Tucano") in Brazil.  Great Panther acquired the mine in March 2019 and conducted 17,400 metres of exploration drilling through the balance of 2019.  Concurrent with the drill program, an evaluation of Tucano's extensive land package was initiated, which is ongoing.  Exploration is divided into "near-mine" and "regional" categories, with a total of US$6.6 million (55,000 metres) budgeted for 2020.

"With a three-fold increase in drilling metres planned for 2020, we are working to capitalize on Tucano's exploration potential," stated Jeffrey Mason, Interim President & CEO.  "We have identified near-mine targets that could lead to the development of new mineralized zones, and we are prioritizing prospects for new discoveries farther afield.  In addition, with the current gold price well above the prices used in the historic pit shell designs, we are analyzing opportunities to expand the existing pits."

NEAR MINE EXPLORATION

An important consideration for near-mine exploration is the distinction between oxide ore and sulphide ore (fresh rock) in that historic production at the mine was focused on the oxide ore due to mill processing constraints.  The completion of a plant upgrade in 2019 enabled the processing of sulphide ore, achieving gold recoveries of about 92%, and opens up the depth extensions for evaluation and exploration.  Furthermore, current gold price levels provide the potential to widen and deepen some open pits, and delineation drilling is being undertaken between the current pit outlines and proposed deeper pit shells.  The 2020 near mine exploration program will consist of 10,000 metres of reverse circulation ("RC") and 18,000 metres of diamond core drilling ("DD") and the following describes the plans for individual target areas.

TAP AB
The four TAP AB pits are entirely in oxide ore and are considered to have expansion potential.  Secondary mineralized zones in the footwall (Carbonate Lodes) and hanging wall (NEO and NEO North Lodes) are to be drilled in more detail as they provide potential to reduce strip ratios and support a deeper pit.  A combined 9,000 metres of RC and DD is planned for 2020 to better define these zones.  Recent intersections below the currently scheduled $1,250/oz pit shell include good grades and widths (see table below and Great Panther press release of July 30, 2019) and, in conjunction with a higher gold price, justify deepening the pits, wherein gold grades increase.

Torres / TAP AB South
A total of 11,000 metres of RC and DD drilling is planned for 2020 to test the southern extension of the AB1 zone adjacent to the existing pit.  This area is located at the structural intersection of the NW-SE trending 'D' zones and the main North-South mine trend and is considered to be a favourable geological setting for mineralization.

Urucum East Pit
An Exploration Report has been filed and accepted by the Agência Nacional de Mineração (Brazilian Mines Ministry) and Great Panther expects the issuance of an Environmental Permit and the granting of a Mine Operating Concession in 2020.  The current resources are based on near surface material and 4,500 metres of additional RC and DD drilling is planned in 2020 to prove up the deeper continuation of the ore.

Urucum North Pit and Underground
Diamond drilling in 2019 was completed just below the existing pit floor in order to better define mineralization for the purposes of targeting a deeper pit.  In contrast, the 3,500 metre 2020 infill drilling program will target the upper "Central Lode" for underground potential and will be based on an improved understanding of the structural controls of higher-grade ore shoots as defined by the 2016 Prefeasibility Study ("PFS").  The Central Lode lies approximately 100-150 metres below the existing pit floor and the South Lodes 1 and 2 lie 100-200 metres below that horizon.  Urucum North has the advantage of good ground conditions in fresh rock that could allow reasonable development rates to optimize underground pre-production costs and time.

URSO / TAP AB3 East
The drill program would seek to extend gold mineralization to depth along a 500 metre strike length, as good grades have been intercepted at depths of 180 metres in oxide material.  A further 5,700 metres for URSO / TAP AB3 East (incremental to the current planned 55,000 metres for entire Tucano program) of RC and DD is being evaluated for 2020 and, if warranted, deeper drilling could ultimately test the underground potential of these zones.

Duckhead
Following a review of previous work, it was concluded that no additional drilling is required at this historic high-grade pit in order to recommence production.  Further, past mining was conducted based on a $1,100/oz pit shell while there is sufficient justification for a pushback to a $1,450/oz pit shell.  Engineering is underway and resumption of mining activity could commence as early as the fourth quarter of 2020.

REGIONAL EXPLORATION

Great Panther holds approximately 2,350km² in various stages of licensing covering a largely unexplored greenstone belt in the Guyana Shield.  The Company's exploration team is strategically prioritizing concessions according to their proximity with respect to Tucano's mill and geological potential.  Most of these targets are early stage based on airborne magnetics, soil sampling, Auger and Rotary Air Blast ("RAB") drilling.  Approximately 27,000 drilling metres are planned for regional exploration in 2020, including 18,000 metres of RAB and 9,000 metres of Auger drilling.

The technical information contained in this news release has been reviewed and approved by Marcelo Batelochi, Director of Exploration and a Qualified Person for the purposes of National Instrument 43-101.  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.
