The 100% Rackla owned, Rivier Property consists of 116 quartz claims covering 2,404 hectares, located in the Watson Lake Mining District 80 kilometres southeast of Ross River, Yukon. The Rivier claims are in good standing until 2022.
The Property was staked in 2010 to cover the source area for anomalous gold and arsenic values detected in regional stream sediment samples. Rackla discovered gold mineralization in carbonate-altered ultra mafics of listwanite lithology. The mineralization is classified as listwanite-associated lode gold type. Pathfinder elements in silt, soil, and rock geochemistry match signature for these types of deposits. The mineralized listwanite exists as an alteration product of and around a structurally controlled ultramafic body that is central to the property.
Three main mineralized zones in the listwanite were identified by a soil geochemistry program, with soils >2 g/t Au in each of the three zones. Summer field programs from 2020 have focused on the listwanite mineralization. The North Zone is a 1.7 km long zone of carbonate alteration and anomalous gold. The South and West Zones are more isolated areas where the listwanite rim outcrops and corresponds with anomalous soil and rock geochemistry.
An airborne magnetic survey conducted by Precision GeoSurveys Inc. correlates very well with mapped geology and geochemistry. The unaltered ultramafic core shows up as a strong magnetic high with a distinct magnetic-lows that rim that coincides with the gold in soil anomalous listwanite. The magnetic low extends to the northeast where the mapped listwanite goes undercover. This leaves the potential for an extension of mineralization and potential location for the hydrothermal feeders.
Using the airborne magnetic survey and the field mapping and sampling, Rackla has outlined high priority drill targets and are planning to drill-test them in the upcoming 2021 field season. A 5,000-meter drill program is being designed for the spring of 2021.
