Great Panther Mining Limited is a new intermediate gold and silver mining and exploration company listed on the TSX and on the NYSE American. Great Panther operates three mines including the Tucano Gold Mine in Amapá State, Brazil, and two primary silver mines in Mexico: the Guanajuato Mine Complex and the Topia Mine.  Great Panther also owns the Coricancha Mine in Peru, which is expected to restart operations in 2020.

The Tucano Gold Mine is located in Amapá State in northern Brazil. The mine is approximately 200 kilometres from Macapá, the state capital.  It is currently the second largest gold producer in Brazil, producing around 145,000 ounces per year from several open pit mines wit ore processed through SAG mill and CIL infrastructure, capable of treating sulphide ore.  Great Panther acquired the mine through the friendly acquisition of Beadell Resources Limited in a transaction that closed in March 2019.

The Guanajuato Mine Complex produces silver and gold concentrate and is located in central Mexico, approximately 380 kilometres north-west of Mexico City, and approximately 30 kilometres from the Guanajuato International Airport.

The Topia Mine is located in the Sierra Madre Mountains in the state of Durango in northwestern Mexico.  The mine produces concentrates containing silver, gold, lead and zinc and earns revenue from custom milling of third-party ore at its processing facility.

On June 30, 2017, Great Panther completed the acquisition of the Coricancha Mine in Peru. The Coricancha Mine is a gold-silver-copper-lead-zinc mine located in the central Andes of Peru, approximately 90 kilometres east of Lima, and has been on care and maintenance since August 2013. The Coricancha Mine has a permitted and operational 600 tonnes per day processing facility along with supporting mining infrastructure. The Company completed a Bulk Sample Program in June 2019 and expects to restart operations in 2020.

Great Panther Mining's exploration properties include the El Horcón, Santa Rosa and Plomo projects in Mexico and the Argosy project in Canada. The El Horcón project is located 100 kilometres by road northwest of Guanajuato, Santa Rosa is located approximately 15 kilometres northeast of Guanajuato, and the Plomo property is located in Sonora, Mexico.    The Argosy property is located in the Red Lake Mining District in Northwestern Ontario, Canada.

The Company continues to evaluate additional mining opportunities focus on the Americas.

Producing -


The Tucano Gold Mine is located in Amapá State in northern Brazil. The mine is approximately 200 kilometres from Macapá, the state capital, and is accessible by the Brazilian federal highway BR-210, or by chartered aircraft.  It is currently the second largest gold producer in Brazil, producing around 145,000 ounces per year from several open pit mines.  Formerly a heap leaching operation, it ran from late 2005 until January 2009, producing approximately 292,000 troy ounces of gold from 8.8 Mt of ore. The property was put under care and maintenance due to problems treating the increasingly transitional material. Beadell Resources Limited acquired the property in 2010 and the process plant was upgraded with the addition of a SAG mill and CIL infrastructure, capable of treating sulphide ore. From November 2012 to June 30, 2017, 17.0 Mt at 1.34 g/t gold containing 735,294 ounces of gold were processed, feed was made up of a blend of pit oxide ore, sulphide ore, spent ore, and historic stockpiles.  Great Panther acquired Beadell Resources Limited in a friendly transaction that closed in March 2019, and holds a 100% interest in the project.


The Guanajuato Mine Complex is Great Panther Silver's flagship operation. The property consists of 32 claims, totalling 2,621 hectares. The concessions are 100% owned by Great Panther's Mexican subsidiary, Minera Mexicana El Rosario, S.A. de C.V. The main claim block covers 4.2 km of the highly significant Veta Madre vein structure and is located on the Central Plateau of Mexico in the State of Guanajuato. The City of Guanajuato, where the mines are located, is 380 km by road northwest of Mexico City and is serviced by an international airport near the city of Leon.


The San Ignacio Mine covers approximately four kilometres of strike length on the La Luz vein system, which is parallel to, and five kilometres west of the principal Veta Madre structure that hosts Great Panther Silver's Guanajuato Mine Complex. Great Panther holds a 100% interest in the Property through its wholly owned Mexican subsidiary, Minera Mexicana El Rosario, S.A.de C.V.


The Topia Silver-Lead-Zinc property is located in the heart of the Topia Mining District in west-central Durango State, Mexico. The property is accessible by road from the city of Durango by traveling north for approximately 200 km on paved Highway 23, and west for 150 km on a paved and gravel road to the town of Topia. The town is presently served by daily small-aircraft flights to the city of Culiacán, which lies 100 km to the southwest. Topia is the principal centre for the area with schools, shops, a small hospital, and public telephone and internet access.

Advanced Exploration -


On June 30, 2017, Great Panther closed the acquisition of the Coricancha Mine, in the central Andes of Peru, from Nyrstar NV (for terms of the acquisition, please refer to the December 19, 2016 press release). The Mine is located in the Province of Huarochirí, approximately 90 km east of Lima and is accessed by the Central National Highway connecting Lima to La Oroya. The travel time by road from Lima is approximately three hours to the processing plant and lower level of the mine. The operation is located in an area of significant relief, and elevations at the property range between 3,000 and 3,920m above sea level.

The Coricancha Mine holds many of the licenses and permits necessary to re-start operations; all valid and in good standing. The project includes an operational 600 tonne per day flotation and gold BIOX® bio-leach plant along with supporting mining infrastructure. The Coricancha Mine has been on care and maintenance since August 2013 when it was closed due to falling commodity prices. The property comprises more than 3,700 hectares in the prolific Central Polymetallic Belt and production at the mine dates back to 1906. Gold-silver-lead-zinc-copper mineralization (approximately 80% gold-silver by value) occurs as massive sulphide veins that have been mined underground by cut and fill methods.

Great Panther completed a Preliminary Economic Assessment in May 2018 and a Bulk Sample Study in June 2019, and expects to restart operations in 2020.

Exploration - 


El Horcón is a Gold-silver-zinc-lead exploration project situated 50 kilometres north of the city of Leon (Guanajuato State), in the state of Jalisco, Mexico, approximately 470km northwest of Mexico City.  More importantly, it is approximately 100 kilometres by road and within trucking distance to Great Panther’s Cata processing plant in Guanajuato.

The property is located on the northwest trend of the prolific Guanajuato mining camp, and hosts mineralized epithermal veins similar to those observed at Great Panther's existing operations. El Horcón is a historic mining operation but the extent of past production is unknown.  It hosts nine known veins, with the Diamantillo Vein traceable on surface for more than four kilometres. Several underground workings exist, the most extensive of which is the Diamantillo Tunnel.

Gold, silver, lead, and zinc mineralization occurs in quartz-calcite veins along structures, the largest of which is the Veta Madre, with a strike length of five kilometres.  There has been limited previous drilling in recent times and Great Panther has conducted only 2,147 metres in 24 holes.  As a result of this work, a small NI 43-101 compliant resource exists, however, given that an operation here would not require a stand-alone plant, the project is potentially viable as a satellite to Guanajuato.  For this reason, the resources are considered to fall under the umbrella of the GMC.

Great Panther owns a 100% interest in the project. There are no known environmental liabilities associated with the mineral claims.


Santa Rosa is a silver-gold exploration project, located approximately 15 kilometres northeast of Guanajuato.  The Project includes a cluster of non-contiguous mineral claims, with most covering segments of historically known veins within the Sierra Vein System.  An additional two claims staked further north make up a total area of approximately 20,400 hectares.  While exploration here is grass-roots in nature, the project is within trucking distance of the Cata processing plant, and it is being evaluated as a potential satellite.

There are no resources on the Santa Rosa Project and no known environmental liabilities associated with the mineral claims.
