Guanajuato Silver Company Ltd. (TSX-V:GSVR) (OTCQX:GSVRF), a growing Mexican-based precious metals producer,is pleased to provide an update on the 2024 drilling program and other exploration and development initiatives at the Company’s wholly owned Pinguico Project located in Guanajuato, Mexico.
Highlights
James Anderson, Chairman & CEO, said, “We value our Pinguico gold and silver project for its near-term organic growth potential within Guanajuato Silver’s growing portfolio of mining assets. Over the past two-years, our focus has been on processing Pinguico’s low grade above ground historical stockpiles; preparing to expand the Level 4 access corridor and drive toward the historical underground stockpile; drilling the near surface San Jose and El Pinguico vein structures; and drilling towards the conceptual target of the probable intersection of the regional Veta Madre structure and the historically high-grade El Pinguico vein.”
Pinguico Extensional Drilling
In 2024, drilling was conducted on the southern portion of the property with the objective of exploring the El Pinguico and San Jose veins along strike to the south. A total of 446 metres were drilled in three drill holes with the following results. Unless otherwise noted, all references in this news release to silver equivalent or AgEq have been calculated using 85:1 gold/silver (Ag/Au):

Pinguico Deep Drilling
In 2024, a single deep drill hole – SP24-003 – was drilled to a 659m core length to advance the Company’s understanding of the relationship between Veta Madre and the El Pinguico vein structure at depth. This drill hole successfully intersected a broad (approximately 60m in core length), highly altered, deformation zone associated with the Veta Madre fault zone – the first time Veta Madre proper has been intersected on the Pinguico property. Within this zone, which is located within the highly productive Guanajuato Conglomerate Unit, the drill hole encountered an interval of stockwork with 0.56 gpt gold over an estimated true width of 1.13m.

After further studying the implications of this potentially important interval, the Company plans to drill a deeper hole toward the interpreted intersection of El Pinguico and Veta Madre in Q2, 2025.

Pinguico Underground Development
At Pinguico, underground mining activities resumed in mid-year, with the objective of continuing the advance at level 4 toward the historical underground backfill stockpile. Mine drifting has advanced over 75 meters to date with the development of a 4m x 4m fully serviceable crosscut. The Company expects to complete the advance in Q2, 2025. During the quarter, production from development contributed an estimated 2,562 tonnes with an average grade of 1.19 g/t gold, 102 g/t silver for 203 g/t silver equivalent.
The underground stockpile ranges from 25 metres to 100 metres in thickness and has an indicated mineral resource of 25,600 tonnes grading 166 g/t silver and 1.67 g/t gold for contained metal of 136,600 ounces of silver and 1,375 ounces of gold.

About Guanajuato Silver
GSilver is a precious metals producer engaged in reactivating past producing silver and gold mines in central Mexico. The Company produces silver and gold concentrates from the El Cubo Mine, Valenciana Mines Complex, and the San Ignacio mine; all three mines are located within the state of Guanajuato, which has an established 480-year mining history. Additionally, the Company produces silver, gold, lead, and zinc concentrates from the Topia mine in northwestern Durango. With four operating mines and three processing facilities, Guanajuato Silver is one of the fastest growing silver producers in Mexico.
Sampling and quality assurance/quality control
Drill core was first reviewed by a Company geologist, who identified and marked intervals for sampling. The marked sample intervals were then cut in half with a diamond saw; half of the core was left in the core box and the other half was removed, placed in plastic bags, sealed and labeled. Intervals and unique sample numbers are recorded on the drill logs and the samples are sequenced with standards and blanks inserted according to a predefined QA/QC procedure. The samples are maintained under security on site until they are shipped to the analytical lab. The analytical work reported on herein was performed by Corporacion Quimica Platinum S.A de C.V., Silao, Guanajuato, Mexico which is independent of GSilver. To validate the Company’s assay results and its preparation procedures, GSilver sends additional random samples representing approximately 20% of all analytical samples to Bureau Veritas in Hermosillo, Sonora, Mexico. Bureau Veritas is an ISO/IEC (International Organization for Standardization/International Electrotechnical Commission) geo-analytical laboratory and is independent of GSilver and its “qualified person”. In order to further validate the Company’s assay results and its preparation procedures GSilver sent additional random samples representing approximately 10% of all analytical samples to SGS Mexico, S.A de C.V, Durango, Mexico. SGS is also an ISO/IEC geo-analytical laboratory and is independent of GSilver and its “qualified person”. Core samples were subject to crushing at a minimum of 70 per cent passing two millimeters, followed by pulverizing of a 250-gram split to 85 per cent passing 75 microns. Gold determination was via standard atomic absorption (AA) finish 30-gram fire assay (FA) analysis, in addition to silver and 34-element using fire assay and gravimetry termination. Following industry-standard procedures, blank and standard samples were inserted into the sample sequence and sent to the laboratory for analysis. Data verification of the analytical results included a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to ensure accurate and verifiable results.
