VANCOUVER, July 30, 2019 /CNW/ - GREAT PANTHER MINING LIMITED (TSX: GPR; NYSE American: GPL) ("Great Panther", the "Company") reports that the first results from in-mine exploration since the Company acquired the Tucano Gold Mine on March 5, 2019 are returning high gold grades over notable widths below the existing TAP AB3 ("AB3") open pit.  Results from 10 of the first 12 holes have returned intersections such as 15.35 g/t Au over 13.55 metres, including 30.94 g/t Au over 5.35 metres, in hole 19TABDD001; and 13.00 g/t Au over 25.50 metres, including 63.40 g/t Au over 5.00 metres, in hole 19TABDD010.  A summary table of drill results (uncut, undiluted) is presented below and plan maps and sections can be found on the Company website here.

Highlights of Mineralized Intervals From TAP-AB3 2019 Exploration Drill Holes

"These first results from the in-mine drilling are highly encouraging and are the first step in unlocking the potential that we see at Tucano," stated Jim Bannantine, President & CEO.  "We have already made significant operational improvements and gold production is increasing.  Exploration of Tucano is a key focus for Great Panther with the objective of increasing the mine life and ultimately enhancing the economics and with the goal of returning significant value for our shareholders."

Tucano's in-mine exploration program (the "In-mine Program") is prioritized on infill drilling below the AB3 and Urucum pits where mineralized zones have demonstrated high potential for depth extension.  These high-grade results from AB3 will add more confidence to the mineral resource estimates and are expected to increase the life of mine of the final pit.  The drilling at AB3 covered a strike length of approximately 350 metres and has locally extended the mineralized zones by more than 100 metres below the existing pit.  Significantly, some of these intersections are below the final pit outline and indicate the potential for an underground resource at AB3.  At Urucum, a prefeasibility study has already been completed on an underground mining scenario below the existing pit.

The In-mine Program contemplates approximately 7,450 metres in 36 holes from two rigs.  To date a total of 12 holes totaling approximately 2,400 metres have been drilled.  The In-mine Program is designed to convert Inferred Resources to Measured & Indicated, while an additional medium-term program will test other near-mine targets.  A further regional exploration program is in the planning stages and will focus on regional exploration of the extensive land package surrounding the Tucano Gold Mine.

The Tucano Gold Mine is located in the Guyana Shield, which was once connected to West Africa and contains many world-class deposits.  Tucano belongs to the sub-category of greenstone-hosted gold deposits known as Iron Formation Hosted Gold Deposits, which includes notable mines such as the historic Homestake Mine, South Dakota (44 million gold ounces produced) and the Musselwhite Mine, northern Ontario (>7 million gold ounces in past production and reserves).

Sample Preparation, Analysis and Security

Drill cores were sampled and logged on-site, then shipped to the independent SGS-Geosol lab in Vespasiano, near Belo Horizonte (Brazil) for preparation and analyzed for gold using a 30-gram sub-sample and fire assay with AAS finish (FAA313 method).  Over-limit samples, 100 g/t gold, are re-analyzed for gold using a 30-gram sub-sample and fire assay with gravimetric finish (FAG323 method).  Control samples, comprising 14% of the sample shipment include standards (5%), lab duplicates (5%), field duplicates (2.5%), and blanks (1.5%).  Drill program design, Quality Assurance/Quality Control ("QA/QC") and interpretation of results were performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices. 

Qualified Persons

The foregoing technical information contained in this new release has been reviewed and approved by Fernando A. Cornejo, P.Eng., Vice-President Projects & Technical Services and Marcelo Batelochi, Director Exploration Brazil, both Qualified Persons (QPs) for the purpose of National Instrument 43-101.
