Toachi Mining Inc., has completed a series of new high grade trenching results and encouraging stream sediment sampling results extending to 1.1 km the known VMS corridor footprint towards the north including trenching of 2.5m of 5.36 g/t Au, 71.18 Ag, 2.14% Cu, 3.22% Pb & 10.86% Zn. Exploration work and resource drilling results completed to date suggest that the La Mina VMS Deposit belongs to a subset of VMS deposits where sulfides have replaced favorable horizon(s) of unconsolidated volcanic and volcano-sedimentary material through a specific mechanism of hydrothermal activity at the paleo sub-seafloor level (after Piercey, S. J., 2015). High-grade massive sulfide mineralization at La Mina is overlain by a thick sequence of mafic volcanic and volcaniclastic rocks with incipient chlorite-epidote-hematite alteration. However, the immediate hanging wall contact to the VMS ore zone has been subsequently affected by the final waning phases of hydrothermal activity, and consequently exhibits a distinct geochemical signature. This thin contact horizon shows silica ± hematite metasomatic replacement with anomalous geochemistry in combinations of many or all of these elements (Au, Ag, As, Ba, Sb, Hg, Cu, Pb, Zn). The above observations were used as a vectoring tool along with understanding of the La Mina deposit lithostratigraphy and unique alteration styles in defining the immediate hangingwall and the footwall to the known VMS ore horizon.
