(Kitco News) Guanajuato Silver is integrating the Bolanitos gold-silver mine into its operations in Mexico’s historic Guanajuato mining district following a $50 million acquisition from Endeavour Silver. The purchase, which closed Jan. 15, 2026, links the Bolanitos operation with the company’s nearby San Ignacio mine, creating logistical and operational synergies across neighboring assets.
Speaking with Kitco Mining in Toronto, Chief Executive Officer James Anderson said the two operations share the same mineralized structures. “Our San Ignacio mine is immediately adjacent to Bolanitos,” Anderson said. “These mines are the same structures, the same vein systems that run through our claims.”
The integration allows Guanajuato Silver to process San Ignacio material at the Bolanitos plant, reducing haulage distances from about 30 km to roughly 2 km. The facility has a processing capacity of about 1,600 tonnes per day, and Anderson said the shorter haul provides an immediate efficiency advantage.
In previous years, San Ignacio material was transported roughly 30 km to another processing facility in the district. The shorter haul could allow Guanajuato Silver to increase throughput while lowering transportation costs as it works toward utilizing more of the plant’s installed capacity.
The acquisition also reflects the company’s broader strategy of consolidating assets within the centuries-old Guanajuato mining district. Anderson said Guanajuato Silver has acquired and restarted five silver and gold mines over roughly the past five years as it builds scale in the region.
“There’s this camp that's 450 years old, so everywhere you go, there’s other opportunities,” Anderson said, referring to dormant mines, waste piles, and tailings that could become economic under stronger metal prices.
District consolidation remains incomplete. Anderson noted that Fresnillo, one of the world’s largest silver producers, owns additional historic properties in the region that could shape future consolidation opportunities.
Operational performance may also depend on metal prices. Guanajuato Silver operates relatively small underground mines that historically carried higher costs, meaning stronger silver prices could significantly improve margins. “$25 silver is a lot different for our company than $80 silver,” Anderson said. “This is a totally different environment.”
The company is also advancing development work at the Pinguico project, where Anderson said Guanajuato Silver is working toward building an underground stockpile that could eventually be processed at the nearby El Cubo plant, located about eight kilometers away.
Beyond internal development, Anderson said the company intends to continue pursuing acquisitions as it expands within the district. “We like to call ourselves Mexico’s fastest growing silver mining company,” Anderson said. “We’ve acquired and put back into production five mines over the last five years.”
