The 100% Riverside owned Clemente Silver Project was acquired using Riverside's 44,000 location proprietary database. It is within close proximity to five active gold-silver mines in the region, including the Cerro Colorado Mine only 7 km to the SE. Clemente is centered on the Sonora-Mohave megashear, a controlling rich belt of orogenic gold and silver deposits approximately 700 km long. The Project has exceptional infrastructure with power, water and road access making the targets easily accessible and cost effective for future drill testing.
An initial field work program discovered high grade silver exceeding 2 kg/t (60 oz/t) in outcrops. The program consisted of 152 rock chip samples and returned assay values from < 5 g/t up to 2,900 g/t silver and gold values from 5 ppb up to 5.4 g/t. Multiple samples returned values over 50 g/t silver, which is uncommon for this region of Mexico and indicates a potentially highly significant target.
Three main mineralized zones that have been identified at Clemente, known as Nuevo Mundo, Mundo and Santa Elena. A fourth high potential target area has a magnetic anomaly under shallow cover just north of the high grade gold and silver outcrops.
Multiple silver/gold workings are located throughout the property, enabling Riverside geologists to gain a better understanding of mineralization potential and sub-surface geology and alteration. Primary exploration targets adjacent to these abandonded mines that show extensive silver mineralization, including a rock chip sample of 2,900 g/t silver.
The Project is dominated by strong hydrothermal alteration, breccias and veining in a basement rock sequence of Precambrian/Cambrian meta-sediments and Precambrian granites that have been multiply sheared with abundant stockwork quartz veining, similar to other areas of the Mojave-Sonora Megashear. Mineralization hosting sediments are primarily dolomites and arenites that have varying extents of alteration suggesting different depths of possible emplacement of mineralization. The Precambrian granites are composed of a 1.8 Ga and a 1.1 Ga suite, reflected in textural variations. These wall rocks act as brittle and locally reactive hosts to epithermal and mesothermal hydrothermal metal bearing fluids that deposited abundant silver along with gold and local base metals.
The primary metallic exploration target is adjacent to abandoned mines and along major through-going shears with extensive silver mineralization. The silver values are of particular note because of pure precious metal zones, as well as silver with base metal target zones. Results were drawn from numerous stockwork veins with variable strikes and dips that indicate high potential for stockwork with wider disseminated mineralization over 10 km of strike length. The veins have historic workings only within the upper oxide zones with minor relict sulfides. The veins can now be tested further through geophysics, trenching, and follow up drilling.
