Geology and Mineralization
The El Quevar property is characterized by silver-rich veins and disseminations in Tertiary volcanic rocks that are part of an eroded stratovolcano. Silver mineralization at El Quevar is hosted within a broad, generally east-west-trending structural zone and occurs as a series of north-dipping parallel-sheeted vein zones, breccias and mineralized faults situated within an envelope of pervasively silicified brecciated volcanic rocks and intrusive breccias. There are at least three sub-parallel structures that extend for an aggregate length of approximately 6.5 kilometers. There are numerous additional target areas on the project that have not yet been tested.
Several volcanic domes (small intrusive bodies) have been identified and mineralization has been found in breccias associated with these domes, especially where they are intersected by the structures.
The principal metal value at Yaxtché is silver, with lesser amounts of lead, zinc, and copper minerals, and accessory gold and antimony. The principal gangues are quartz, pyrite, and barite.
