Osino Resources Corp. announced assay results from the shallow drill program to collect bedrock samples at Twin Hills Extension. The drill program tested a portion of the gold anomaly in calcrete which stretches for 8km to the southwest from the original 3km Twin Hills prospect. Calcrete is a hardened, calcium-rich layer in or on top of a soil which is formed as a result of climatic fluctuations in arid and semiarid regions. Calcite is dissolved in groundwater and, under drying conditions, is precipitated as the water evaporates at the surface. Rainwater saturated with carbon dioxide acts as an acid and dissolves calcite and then redeposits it on the surfaces of the soil particles; as the spaces between soil particles are filled, an impermeable crust is formed. This crust can vary from less than 1m to more than 50m thick. Bedrock drilling was carried out on two fence lines with holes 20m apart for a total of 49 holes. The holes were drilled vertically through calcrete to test the top of the weathered bedrock with the objective of confirming that gold anomalies at surface correlate with gold in the bedrock. The average thickness of the calcrete in this area is 19m and the bedrock lithology in all holes is biotite schist, similar to the lithology outcropping at Twin Hills. The maximum gold assay value was 2.3g/t and a further seven bedrock samples had values between 0.3g/t and 1.1g/t gold. These results indicate that the gold anomalies in calcrete at surface over the 11km strike length are representative of gold in the bedrock below the thick cover. In addition, the highest values at surface on the two lines drilled are directly above the highest bedrock grades 19m below. This close spatial correlation means that surface calcrete samples can be used to detect gold in bedrock under deep cover.
