In 1992, Major General Resources drilled a gold showing on the regional Fry-McVean shear zone located several hundred meters to the north and parallel to the 2-mile long subordinate Riedel shear zone target. The best drill intersection was 24 g/t Au over 0.5 m other holes returned assays of 2.65 g/t Au over 1.7 m and lower.
In 2008 the position of the 32-km long Fry-McVean shear zone was revealed by Ontario Geological Survey mapping.
By examination of the Ontario Geological Survey’s airborne magnetic and VLF-EM survey maps, this writer identified the 8.5 km long Riedel shear zone that is the focus of exploration. 110 miles to the west of the 26 million ounce Campbell-Red Lake mine at Red Lake is hosted in Riedel shear zones with proximate iron carbonate alteration near the ore veins.
In 2011, this writer conducted a 1,087 humus soil sample survey to cover the Fry-McVean shear zone and the subordinate Riedel shear zone. The survey revealed that a 2-mile length of the Riedel shear zone corridor was anomalous with 314 anomalous indicator element assays. This target is open to the east for an additional 2.5 miles.
The writer examined the anomalous corridor by ground truthing scattered outcrops near the overburden-covered anomalous sample stations. This work revealed that the mafic volcanic flows in the outcrops had been altered metasomatically to iron carbonate (ferric dolomite) rock by hydrothermal solutions with accessory tourmaline crytals. These minerals are gold indicators that are found proximate to gold deposits at Timmins and at Red Lake Ontario.
The identification of major long and wide CD anomalies (50 -100 m wide) within a long and wide Riedel Shear Zone (8.5 km long X 400 m wide) combined with 314 anomalous gold indicator anomalies in the nearby soil over a 2-mile strike length, together provide a means of identifying gold drill targets with a high degree of integrity. The CD anomalies are probably due to sulphide minerals in the Riedel shears within the concealed bedrock that have generated the indicator element ions in the humus soil-namely: As, Fe, Sb and Mo together with Au.
In 2020, this writer commissioned Abitibi Geophysics to conduct a 17-line VLF-EM ground survey over half of the 2-mile long gold target,
Abitibi Geophysics reported their Interpretation of the
VLF-EM data. Abitibi identified a minimum of eight (8) conductive axes of 100 to 500 m in length, as well as eight (8) isolated conductive sources on the Linjog Lake grid.. On the Unnamed Lake grid, four (4) conductive axes (100 m to 400 m strike length), and two (2) isolated conductive anomalies were reported.
The identification of major long and wide CD anomalies (50 -100 m wide) within a long and wide Riedel Shear Zone (8.5 km long X 400 m wide) combined with 314 anomalous gold indicator anomalies in the humus soil located close to or over the CD anomalies on the 2-mile target strike length, together provide a means of identifying gold drill targets with a high degree of integrity. The CD anomalies are probably due to sulphide minerals in the concealed bedrock that have generated the indicator element ions in the humus soil-namely: As, Fe, Sb and Mo together with Au.
Karous-Hjelt Current Density (CD) anomalies from ground VLF-EM surveys have revealed orogenic gold deposits on line profiles (pseudo-sections)in the following mines:
o Padavurra gold mine in India
o Cominco’s Snip mine in British Columbia
o And Harte Gold Mine;s Sugar Zone gold mine
o
Hence, CD anomalies together with related Apparent Resistivity (AR) anomalies are used to identify targets for gold discovery. An AR anomaly was identified over the Fenelon gold discovery of Wallbridge Mining in Abitibi, Quebec.34 proposed diamond drill hole sites and profiles at Linjog Lake and Unnamed Lake are designed to intersect strong Current Density anomalies and/or humus gold geochemical anomalies. Maps of the drill hole locations and tables of proposed drill hole data have been prepared.
