The Cerro Blanco project is located approximately 80 kilometres east of Guatemala City, near the border with El Salvador and only five kilometers from the Pan American Highway. The nearby the town of Asuncion Mita—a community of nearly 15,000—provides excellent infrastructure for the project.
Cerro Blanco, Guatemala
The deposit at Cerro Blanco has been defined over a strike length of one kilometer and is open at depth, to the north and south. The resource is from a typical hot spring-style epithermal, low-sulfidation or quartz-adularia-type, vein deposit. The vein system is within Tertiary volcaniclastic sediments, andesitic and dacitic welded tuff rocks and, to a lesser extent, in Cretaceous limestone and fine to coarse siliceous to argillaceous clastic sediments. The stockwork vein system extends in a northwest trend for three kilometers before reaching post-mineral basalt cover. A sinter and silica replacement blanket is underlain by basin-fill volcaniclastic rocks including re-worked Cretaceous sediments and is underlain at depth by a thick, pervasively chloritized, dacitic welded tuff. Stockwork quartz/calcite veining is pervasive in the permeable volcaniclastic sequence and forms more discrete but generally higher-grade veins near and in the dacite.
