- Guanajuato Silver Company Ltd. is a precious metals producer, primarily engaged in the reactivation, operation, and development of historic silver and gold mines in central Mexico. The company produces silver and gold concentrates from its El Cubo Mines Complex, which features high-grade epithermal-vein underground mining with 45,000 tonnes per month processing capacity; the Valenciana Mines Complex, encompassing over 4km strike length along historic veins active since the 1500s; and the San Ignacio Mine, where high-grade silver-gold material feeds nearby processing; as well as silver, gold, lead, and zinc concentrates from the Topia Mines Complex in Durango state, utilizing separate lead-silver-gold and zinc circuits. It operates three processing facilities, including the El Cubo mill, Valenciana-area Cata mill, and Topia facilities, serving the prolific 480-year-old Guanajuato Mining District and targeting bulk precious metal concentrates for international markets. Incorporated in 1978 under British Columbia law and headquartered at 999 Canada Place in Vancouver, Canada, the company trades on the TSX Venture Exchange under ticker GSVR.V.
In recent developments, Guanajuato Silver signed a definitive agreement on November 21, 2025, to acquire the Bolanitos gold-silver mine and related assets from Endeavour Silver Corp. for up to US$50 million, including US$40 million upfront (US$30 million cash and US$10 million in shares) and US$10 million in contingent production-based payments, with closing expected in January 2026 pending TSXV approval; this transaction adds Bolanitos' 1,600 tonnes per day flotation plant, three producing mines (San Miguel, La Luz, Lucero), the past-producing Golondrina and Cebada mines, and the Belen exploration project, enabling integration of San Ignacio material to boost mill utilization from 73% and expand to five operating mines. The company also announced the temporary closure of the Cata mill for optimization ahead of Bolanitos integration, redirecting Valenciana material to El Cubo to maximize plant efficiencies; additionally, in Q3 2025 it reported an $11.3 million working capital increase driven by mine cash flows. Previously known as Vangold Mining Corp., it acquired key assets like Valenciana, San Ignacio, and Topia from Great Panther Mining in 2022, establishing its current multi-mine platform.
