GSilver Furthers Consolidation of the Guanajuato Mining District
VANCOUVER, BC / ACCESSWIRE / August 4, 2022 / Guanajuato Silver Company Ltd. (the “Company” or “GSilver“) (TSXV:GSVR)(OTCQX:GSVRF) is pleased to announce that it has closed the purchase of Great Panther Mining Ltd.’s (“Great Panther“) (TSX:GPR) Mexican subsidiary Minera Mexicana Rosario S.A. de C.V. (“MMR“), which owns the currently operating Topia mine and production facility in the state of Durango, Mexico (“Topia“), and the San Ignacio mine, the Valenciana Mine Complex (“VMC“), and the Cata processing plant in Guanajuato, Mexico (the “MMR Acquisition“), first announced in the Company’s news release of June 29, 2022.
- GSilver expands to five mines and three production facilities.
- Production from San Ignacio expected to restart within 90 days
- Continued production from the Topia Mine anticipated to exceed 1.1 million AgEq ounces this year.
Closing the MMR Acquisition
GSilver and Great Panther closed the MMR Acquisition on August 4, 2022 with the execution of customary closing documents in Mexico and Canada and with the payment to Great Panther of US$14,700,000, subject to certain closing adjustments, satisfied with US$8,000,000 in cash and the delivery to Great Panther of 25,787,200 common shares of the Company.
Chairman and CEO James Anderson commented, “We look forward to integrating our new assets with current operations expeditiously. GSilver plans to restart the San Ignacio mine as soon as practicable, and deliver its silver and gold mineralized material to our El Cubo plant for processing. In the months ahead, we plan to do the same at the Valenciana Mine Complex – shipping mineralized material to El Cubo for processing – prior to re-starting the Cata mill in 2023. Meanwhile, at Topia, our other new asset, work will begin immediately to assess optimization opportunities to existing operations in both the mine and the plant.”
MMR Assets Purchased:
Great Panther referred to its five mines near the centre of Guanajuato as the “Guanajuato Mine Complex” or “GMC”. From north to south, these mines are called Guanajuatito, Valenciana, Cata, Los Pozos, and Promontorio. Henceforth, GSilver will refer to these mines collectively as the “Valenciana Mine Complex” and to the accompanying processing plant, which has a nameplate capacity of 1,200 tonnes per day, as “Cata”.
VMC has been in near continuous operation since the 1500s and is situated along the highly productive Veta Madre (‘Mother Vein’), encompassing a strike length of 4.2km. Valenciana became one of the premier silver mines in the world and, for a time, accounted for up to one-third of global annual silver production.
Historical in-situ measured and indicated resources at the Valenciana Mine Complex, as reported by Great Panther (effective date: July 31, 2021), totalled 251,666 tonnes grading 250 gpt Ag and 1.76 gpt Au (400 gpt AgEq) for 3.23M AgEq ounces, with additional inferred resources of 220,760 tonnes grading 225 gpt Ag and 1.95 gpt Au (391 gpt AgEq) for 2.77M AgEq ounces. See the mineral resources table for Valenciana below. (1)
The Cata processing plant, which forms part of the Valenciana Mine Complex, has a nameplate capacity of 1,200 tonnes per day (36,000 tonnes/month) and remains in good working condition. The plant is a traditional crushing, grinding and floatation system that produces a high-grade silver-gold concentrate.
Valenciana was put on care and maintenance by Great Panther in November 2021 because of a lack of tailings capacity.
The San Ignacio Mine is located approximately 20km by road west of the city of Guanajuato and 38km from GSilver’s El Cubo mill. Mineralization exists within an epithermal quartz vein system called ‘La Luz’, which is a large regional tectonic structure that also hosts Endeavour Silver’s Bolanitos Mine.
San Ignacio has operated for 10 years, with high grade silver and gold material continually trucked to Great Panther’s Cata mill for processing. GSilver intends to transport material from San Ignacio to El Cubo for processing.
Historical in-situ measured and indicated resources at San Ignacio as reported by Great Panther (effective date: July 31, 2021) totalled 267,828 tonnes grading 145 gpt Ag and 2.80 gpt Au (384 gpt AgEq) for 3.30M AgEq ounces, with inferred resources of 445,217 tonnes grading 178 gpt Ag and 2.65 gpt Au (404 gpt AgEq) for 5.78M AgEq ounces. See the mineral resources table for San Ignacio below. (1)
San Ignacio was put on care and maintenance by Great Panther in January 2022 due to a lack of tailings capacity.
Topia Mine and Mill, Durango, Mexico:
Great Panther has operated the Topia Mine in north-eastern Durango since 2004; the mine includes a 260 tonnes per day flotation processing plant that is currently operating at close to full capacity. The mineral deposits at Topia are different than those seen at Valenciana and San Ignacio, which exclusively produce precious metals. Mineralization at Topia exists as polymetallic epithermal veins that contain high-grade concentrations of silver, zinc, lead and gold. The Topia veins consist mainly of massive galena, sphalerite, and tetrahedrite in a gangue of quartz, barite, and calcite.
Historical in-situ measured and indicated resources at Topia as reported by Great Panther (effective date: March 31, 2021) totalled 331,800 tonnes grading 609 gpt Ag, 1.84 gpt Au, 4.4% Pb and 4.5% Zn (1,041 gpt AgEq) for 11.10M AgEq ounces, with inferred resources of 274,600 tonnes grading 592 gpt Ag, 1.44 gpt Au, 3.35% Pb and 3.63%Zn (932 gpt AgEq) for 8.22M AgEq ounces. See the mineral resources table for Topia below. (1)
Topia is currently in operation; the mine produces a lead-silver-gold concentrate and a separate zinc concentrate.
Valenciana and San Ignacio – Effective Date: July 31, 2021
Topia mine – Effective Date: March 31, 2021
GSilver is not treating these estimates as current mineral resources as a qualified person on behalf of GSilver has not done sufficient work to classify these estimates as current mineral resources. (1)
Closing the MMR Acquisition – Details:
On closing of the MMR Acquisition today, GSilver paid US$14.7M to Great Panther as follows:
- US$8.0M in cash.
- US$6.7M in GSilver common shares at a deemed price of C$0.335 per share, for a total of 25,787,200 GSilver shares (the “Consideration Shares“).

- These estimates have been extracted from the following National Instrument 43-101 technical reports filed by Great Panther under its profile on SEDAR at www.sedar.com and use the definitions of “Mineral Resource” set forth in the CIM Definition Standards, adopted May 10, 2014, by the Canadian Institute of Mining, Metallurgy and Petroleum:
- NI 43-101 report on the Guanajuato Mine Complex dated February 28, 2022 (effective date July 31, 2021) prepared on behalf of Great Panther by Robert F. Brown, P. Eng, and Mohammad Nourpour, P. Geo., (together the “GP Qualified Persons“) and titled “NI 43-101 Mineral Resource Update Technical Report on the Guanajuato Mine Complex, Guanajuato and San Ignacio Operations, Guanajuato State, Mexico” (the “Guanajuato Report“); and
- NI 43-101 report on the Topia Mine dated February 11, 2022 (effective date March 31, 2021) prepared on behalf of Great Panther by the GP Qualified Persons and titled “NI 43-101 Report on the Topia Mine Mineral Resource Estimates as of March 31, 2021″ (the “Topia Report“),
Such estimates are subject to certain assumptions regarding grade, metal prices, currency exchange rates, costs, metals production rates, schedule of development, labour, consumables and other material costs, markets and market prices as more particularly set out in the reports. AgEq oz were calculated using 85:1 Ag:Au ratio. AgEq gpt and AgEq oz figures reported for Topia have been extracted from Great Panther’s news release dated February 11, 2022.
The Guanajuato resources were estimated from six area-specific block models at Guanajuato, and eighteen block models at San Ignacio. A set of 44 wireframes representing the mineralized zones served to constrain the block models and data subsequently used in Inverse Distance Cubed (ID3) Au and Ag grade interpolation. The geological interpretation was provided by Great Panther. Wireframe modelling was completed using MICROMINE and Leapfrog 3D geological modelling software and grade estimation and geological modelling completed using by MICROMINE software. See the Guanajuato Report for further details of the key assumptions, parameters, and methods used to prepare the resource estimate.
The Topia resources were estimated from 10 mine area-specific block models. A set of 60 wireframes representing the mineralized zones (veins) served to constrain both the block models and data subsequently used in Inverse Distance Cubed (ID3) gold, silver, lead, and zinc grade interpolations. Each block residing at least partly within one of 60 wireframes received a grade estimate. The full operational cost cut-off value as calculated by Great Panther’s mine operating staff ranges from US$202 to US$345/tonne for different areas based on full mine operating costs (mining, milling, administration). Block model silver, gold, lead, and zinc grades have been converted to an US$ NSR value using an NSR “calculator” which takes into effect metal prices (long term projected to be US$20.00/oz silver, US$1,650/oz gold, US$0.85/lb lead, and US$1.20/lb zinc), plant metallurgical recoveries of 92.4% for Ag, 55.4% for Au, 94.3% for Pb, and 90.5% for Zn, concentrate shipping charges, and proprietary smelter terms. Blocks with an NSR value equal to or greater than the operations full cut-off costs were tabulated into the mineral resource estimate for each zone. The cut-off value was applied to each block estimated in the resource block model. Mineral Resource blocks are only considered Measured or Indicated if they are within 10m or 20m of underground channel sampling associated with mine development. See the Topia Report for further details of the key assumptions, parameters, and methods use to prepare the resource estimate.
GSilver is not treating these estimates as current mineral resources as a “qualified person” on behalf of GSilver has not done sufficient work to classify the estimates as current mineral resources and therefore such estimates should not be relied upon. A thorough review by GSilver’s “qualified person” of all historic data, along with additional exploration and validation work to confirm results and estimation parameters, would be required in order to produce a current mineral resource estimate for the Valenciana and San Ignacio mines and Topia.
