The Lobos project is located in northwestern Sonora, Mexico. The property 2,830 hectare lies along the Sea of Cortez, approximately 90 km from Puerto Penasco, the largest major center in the region. Silvermex owns100% of the project.
Geology
A sequence of Tertiary volcanic flows and agglomerates, varying in composition from andesite to rhyolite, overlay a granitic batholith that forms the base of the lithological column in the region. The entire sequence has been subjected to severe tectonic forces producing wide breccia zones, faults and fractures that are often intruded by dikes. In many locations this sequence is covered by Quaternary conglomerates and basalts and Recent alluvial deposits.
In the northwest and southern portion of the claim block the geology consist of a granodiorite basement intruded by an intrusive of granitic composition. Rhyolite dikes and tectonic breccias are often hosted in zones of weakness in the granite. The regional north-west to south-east trend exposed is exposed for 350 meters before plunging below the volcanic sequence.
These tectonic breccias zones appear to be important controls as they host stockworks of quartz-chalcedony veins and veinlets and black calcite that appear to be related to the silver, lead, zinc sulphide (shalerite), zinc oxide (calamine) and copper mineralization. Moderate to strong oxidation of pyrite, forming boxworks of limonite, and sericite are common alteration products in the breccias.
In the southern portion of the claim, a similar mineralized breccias zone with strong oxidation and quartz-chalcedony veins and veinlets has been identified. This zone offers additional exploration opportunity.
Exploration
Since the completion of the initial sampling program, no additional work has been completed on the Lobos project. The early stage exploration project remains in the Company's inventory for a time when management determines an opportune time to diversify the focus of its exploration efforts.
