Exploring the Sierra Madre of Mexico for gold and base metals.
The Company has the mining rights to about 1.4 kilometers of strike length of this vein system in the southeastern part of the Property, and 300 meters of strike length north of the internally held third-party concession. In the southern area, principal veins include La Tárantula, Tatemales and Macuay. These veins strike northwesterly and dip steeply to moderately northeasterly. Near-vertical northerly trending veins between La Tárantula and Tatemales Veins include La Víbora and El Nito Veins. These are mineralized tension gashes or Riedel shears between the larger northwesterly trending structures. In the northern area, principal veins are Lentes, Tlacuaches, Chiveras and Huaraches. These veins strike northwesterly, but dip southwesterly, not northeasterly like the veins to the south. Hostrocks in both the northern and southern areas are bimodal ignimbrites and shoshonites of probable Paleocene age.
In this area, the principal structure is La Tárantula oriented 325°/55° NE. The Company has sampled about 450 meters of strikelength northwest and southeast of Cerro La Flauta del Placer. La Víbora is orthogonal to La Tárantula with an orientation of 188°/81° WNW. La Víbora is characterized by shingle breccias of elongate rock cemented by microcrystalline grey quartz and sulfide. Shingle breccias form by episodic spalling and detachment of rock slabs from fault planes. El Nito outcrops about 975 meters northwest of La Víbora and is oriented 330°/80° NE. It is up to 1.7 meters wide and consists of rose quartz breccia with radial black mica surrounding the breccia fragments. It has been sampled over 100 meters of strike length. No diamond drilling has been done at El Placer Sur.
