The Tres Hermanas Property comprises 3671 hectares , covering a mountainous area in the vicinity of the village of San Sebastian Rio Dulce, some 50 kilometers southwest of the City of Oaxaca. The property consists of three contiguous claims, owned 100% by Continuum Resources Mexico S.A., a subsidiary of Continuum Resources Limited. The center of interest is the old Tres Hermanas Mine, which was exploited on five levels for silver prior to the Mexican War of Independence. These adits were mapped and sampled in 1926, but are no longer accessible. Studies in 1926 demonstrated that the deposit yielded average grades of 8.24 oz/t Ag, 4.67 % Pb and 10.77 % Zn and these studies also concluded that that the average ore contained 5.4% Galena, 16.2% sphalerite and 13.7% pyrite, with minor copper sulfides.
The deposit consists of a system of veins following shears. The main vein in the old workings has been described as somewhat erratic in width and mineralogy. Although there is some quartz of epithermal character, most of the vein is sulfides. Silver, lead, zinc and molybdenum are the elements of value, while the gangue includes pyrite, arsenopyrite and barite, in addition to some quartz. Much of the sulphides occur as a fine, black intergrowth.
Recent sampling conducted by Continuum geologists has demonstrated anomalous values contained within the footwall and hanging wall of the main structure over tens of metres. This “Halo” mineralization contains anomalous values of Cu, Pb, Zn, Ag, and Mo. Exploration objective going forward will consist of evaluate the width, depth and strike extents of both the halo, and high grade vein style mineralization.
