GR Silver Mining and Kingsmen Resources released results from drilling programs in Mexico during the week. Both companies’ results are from just one hole at each property.

GR Silver Mining results are from a step-out drill hole that indicates continuity in the Parallel Breccia Target 500 m from the outlined resource at the San Marcial deposit within its Plomosas project in Sinaloa. Although mineralization at San Marcial has been recognized as of intermediate sulfidation epithermal affinity, the latest drillhole is reaching a higher temperature alteration assemblage, with tourmaline-actinolite-albite-K feldspar, overprinted by quartz-pyrite and late-stage irregular chlorite-hematite veining. Coupled with the high copper and tungsten (up to 0.62% W over 9 m) values, GR Silver is interpreting an epithermal porphyry related system.

Kingsmen Resources provided results from drilling at the 8,500 ha Las Coloradas project in Chihuahua. The hole was drilled on the La Soledad structure “to test for depth extensions to the mineralization mined by ASARCO in the period 1943-1952”. The mineralization intercepted includes sphalerite, galena, arsenopyrite, pyrrhotite, and pyrite, returning high values of pathfinder elements antimony, bismuth, indium and arsenic. The deposit type is very likely to belong to the intermediate sulfidation epithermal system category, as many other deposits in the Parral mining district.
