In Q4 2019 production for GMC was sourced from both the San Ignacio Mine and limited areas of the Guanajuato Mine for which mining had been suspended for the previous three quarters to allow for a focussed exploration program. This explains the lower year-over-year production levels, as planned by the Company. The exploration program at the Guanajuato Mine advanced with three drill rigs in operation with the objective of outlining in-situ blocks of higher-grade mineralization and increased mill feed from the Guanajuato Mine in 2020.  The Company expects to release an updated NI 43-101 Mineral Resource estimate before the end of March 2020 for the San Ignacio and Guanajuato mines. The Topia Mineral Resource update is targeted to be completed in July 2020.

Corporate Update and Outlook

Tucano Gold Mine – Urucum Central South Pit (“UCS”)

As noted in October 2019 Company press releases, a geotechnical issue in the west wall of UCS was discovered on October 6, 2019.  As a result of this issue, UCS was removed from the fourth quarter 2019 production plan to secure and monitor the pit.  Great Panther has carried out a structural review and identified a combination of structures that are somewhat unique to UCS in the zone of the failure.  This combination of structures was not observed, nor evident elsewhere in other Urucum pits or Tap pits.  Prior to the restart of drilling and blasting operations at UCS in mid-2020, a more extensive geotechnical investigation is planned that includes core drilling and structural mapping to identify the critical structure in the UCS pit so that appropriate steps can be taken. To partly compensate for the loss of UCS production in the fourth quarter of 2019, production from the Urucum North and Urucum South pits was accelerated.

As previously reported in the October 30, 2019 press release, the Company has engaged consultants to advise on conventional measures required to bring UCS safely back into production.  Unloading and pre-stripping of free-diggable failed material from the top of the open pit has currently commenced under strict geotechnical controls.  Pre-stripping that requires drilling and blasting is scheduled to commence in mid-2020 following the rainy season, while ore mining is targeted for 2021, as originally planned.

Mineral Resource and Mineral Reserve Updates

The Company has engaged Roscoe Postle & Associates Inc. (“RPA”) as its independent mining and geological consultants in connection with the preparation of an updated Mineral Resource and Mineral Reserve estimate for Tucano with an effective date of September 30, 2019. The completion and announcement of the updated Mineral Resource and Mineral Reserve (“MRMR”) estimate is expected before the end of March 2020 for Tucano, as are updates for the Guanajuato and San Ignacio mines.  An update of the MRMR for Topia is planned for July 2020.

Exploration Outlook

Expanded exploration activity at Tucano and GMC is a strategic priority for the Company in 2020.  At Tucano, Great Panther has planned approximately 55,000 metres of drilling as an initial program to be completed during the year, with an emphasis on the first half of the year.  Most of this drilling will be focussed on targets contiguous to mining areas in the existing north-south trending mine corridor, designed to discover resources and reserves that can be added to the existing mine plan.  Approximately 3,500 drilling metres are currently scheduled to target extensions from the open pit resources to potential underground deposits.

The regional exploration program at Tucano is focussed on three of the most prospective regional targets in Tucano’s expansive land package.

Ongoing progress and results of the Tucano exploration will be evaluated at mid-year, with the potential to further expand and refine exploration activities in the second half of 2020.

At GMC, the 2020 drilling program calls for 8,500 metres at the San Ignacio mine and approximately 14,400 metres at the Guanajuato mine.  The 2019 drilling program has already delivered returns in terms of resource blocks that are being engineered into the short term mine plan.  The 2020 GMC program is similarly focussed on adding resources that can augment the existing near and medium term mine plan, and further increase the output from the Guanajuato mine to complement San Ignacio planned ore feed for 2020.


In July 2019 Great Panther reported completion of a Bulk Sample Program wherein the Company had milled 5,100 tonnes of newly mined ore from the Constancia and Escondida veins, confirming key operating assumptions, including productivities, grades, and mill operation contained in its Preliminary Economic Assessment (“PEA”) announced in May 2018.  In October 2019, an ore processing campaign commenced to mill approximately 28,000 tonnes of additional old ore stockpiles that were determined to be economically viable.  This milling campaign to generate incremental net revenue is expected to be completed in the first quarter of 2020, after which time, the mine will return to care and maintenance while the Company conducts additional engineering and operational planning to further optimize and de-risk the project.
