In 2018, seven gold-bearing veins were examined and sampled, and several more were discovered during successive property visits. Based on personal observations of mineralised exposures, artisanal diggings/pits, tunnels and adits, individual veins have estimated minimum observed lengths of 50 metres up to 400 metres. They are generally parallel, with azimuthal trends from 030o to 060o, and overall steep to sub-vertical dips, generally from NW 60o to 85o. Vein widths may reach 0.5 metres, e.g. at Esperanza-Bonanza. Associated alteration is typically characterised by chlorite+/-carbonate+/-argillic minerals +/- sulphide mineralisation. Alteration widths may range from several cm to almost a metre.
Without systematic exposure of the veins, it is difficult to determine width (and grade continuity) of any one vein. Veining does pinch and swell, which is a normal phenomenon for the area, and in some cases, splits or branchiates.
In June, 2020, 10 channel samples were collected under remote supervision by R. Sanabria with a local geologist in representative areas of the vein.
The tunnel mapping and sampling notes the variability of gold values in punctual locations along the vein, ranging from 102.42 g/t Au in the higher end to 15.74 g/t Au in the lowest end. The vein ranges between 10cm and 35cm wide, locally blowing up to 50cm in width. Vein is characterized by a gangue of quartz, and minor carbonates (Calcite, Mn-Calcite), chlorite and sericite. Sulphides range from 10% to almost 80%, with pyrite being the dominant sulphide (>50% of the total sulphide content)) with variable amounts of galena, sphalerite and chalcopyrite. Gold to sulphides ratio seems to be conspicuous along the entirety of the vein.
