Though topography is steep in the surroundings of Las Minas, extensive mining has been carried out throughout some of the most challenging areas. At present, all of the targets being investigated offer very easy access, being on level ground near roads. The total relief on the project is just under 800m.

At an altitude of 1400m, Las Minas has a temperate climate, with summer maximum temperatures of 28°C and winter minimums of 4°. The rainy season from June through September is not intense, with stiff showers possible in the late afternoons and over nights. Most exploration activities can be accomplished 12 months a year.

Mexican Gold maintains a friendly, constructive relationship with the local inhabitants and town councils. The company makes regular donations to local schools and town facilities. During exploration programs, Mexican Gold is the town’s largest employer and our employees are proud to be a part of the excitement surrounding the potential revival of the mining traditions of the region.

The package of cretaceous carbonate rocks and plutonic intrusives is the horizon of economic interest. Up to 1000m of its stratigraphy is intermittently exposed by the erosion of deep canyons between the high volcanic plains and the low-lying coastal strip. Many of these canyons mark the presence of structures within the carbonate platform, some of which can be traced for tens of kilometres. The carbonate rocks are relatively pure and only weakly deformed, with locally extensive marble development up to 500m in thickness and skarn of up to 200m when in contact with large volumes of plutonic rock.

The most prominent and economically important intrusive lithology in the Las Minas area is a highly evolved, medium grained dioritic phase composed of calcium-rich plagioclase, generally 10 to 15% hornblende +/- biotite and various Fe-Ti oxides. On the Mexican Gold claims this dioritic rock forms a thick sill underlying the entire claim area, a stock complex over 2km in diameter, and numerous smaller dikes and sills. All of these types of intrusive features have Au-Cu-Ag mineralized skarn and other mineralization styles and commodities associated with them. The historic mines and showings on the Mexican Gold claims are found, regardless of commodity affiliation, over 800m of stratigraphy. The system is interpreted as a mid-crustal, high temperature environment.

Santa Cruz

The Santa Cruz deposit is a series of dipping, stacked lenses 8-40m thick, located 100 to 150m above the SE portion of the El Dorado. These mineralized lenses occur within a greater package of exo and endoskarn in a corridor approximately 185m wide by 120m thick by 120m deep. Between the two deposits is marble or inter-mineral endoskarn dikes and sills, much of it lying in the intermittent hyrothermal breccia zone. Santa Cruz is exposed on a steep slope along its entire west side, and continues across a small canyon in to the Nopaltepec target.

Much of the character of the mineralization at Santa Cruz is very similar to El Dorado, though the former features notable sulphide redistribution (both destruction and re-concentration), likely through the action of multiple interpenetrating dikes and sills of calcic dioite and endoskarn.

There is also further suite of silica-poor minerals (olivine-augite-serpentine) proximal to a sheeted dike complex (or stock) which marks the south end of the marble / skarn / mineralization.

This vertically-extensive volume of intrusive rock is virtually identical in chemistry, mineralogy, texture and alteration schemes to the dioritic sill underlying the region, and shows mineralized skarn developed on its north contact.
