Wilkinson Mountain: Gabbro with disseminated chalcopyrite
In the Wilkinson Mountain area, the initial discovery of quartz float containing up to 2.05% Cu (#148) occurred in 2015. To the north, near Mount McNair, a cluster of gabbro boulders containing up to 1% disseminated Cu (chalcopyrite), over an area measuring approximately 200 m x 150 m, was located up-ice from the original discovery (#224). In 2016, subcrop or outcrop containing a similar style of mineralization, with up to 0.6% Cu, was identified 550 m northwest of the original Mount McNair boulder cluster (#289).
In 2017, two lines of IP, 2 km long and approximately 800 m apart, were acquired. A mafic dyke out crop at the northwest end of L84E-1300N is coincident with anomalous Cu values in soils. As interpreted from the IP data, this dike is at least 400 m wide, plunges 45° to the southeast, and extends to depths of more than 450 m. A chargeability inversion anomaly exists under the main road, on station # 500N of IP Line 0, and a similar anomaly exists on Line 1, at approximately the same location. IP line data (2 South), collected in 2015, is also interpreted as a chargeability high coincident with high Cu assays from surface, approximately 4 km to the southeast of Mount McNair.
A campaign of five IP lines was performed during the summer of 2019 and the lines revealed a continuity in chargeability anomaly of the previous IP's done in 2017. The chargeability seems to indicate a large target under and along the main Bathurst road close to Mount McNair. Last October a trenching survey uncovered outcrop of metasediment with mineral anomalies up to 74 ppm Cu, 27.5 ppm Co, 51 ppm Ni, 63 ppm Zn, 3.54% Fe, and 0.31% S. This trench was excavated 10 m west of IP L4 of 2019.The chargeability (25-26) there indicates mineralization close to the surface.
Follow up work in 2020 tentatively includes trenching, additional soil geochemistry and IP surveys, aero-mag and aero-vlf. We are presently looking at new drone technology.
