Oct 17, 2019 (Therese Pettigrew) - The stripping exposed a pyrite-mineralized chert with calc-silicate and graphite horizon. The horizon is plus two meters in width, is stratified with calcareous metasediments, and trends in a W-S.W. direction. This prospective zone was traced for some 140 meters through cross trenching (Assessment report 42E12NW0443).

Oct 17, 2019 (Therese Pettigrew) - Trench No. 3 returned an assay of 0.23 Au/ton over 0.30 meters from a pyrite-mineralized chert. In trench No.1, a sample taken across 1.10 meters of chert and graphitic metasediment assayed 0.26 oz/ton Au. All of the 4 holes drilled carried anomalous gold values over widths of 20 to 30 feet. The best assay result was obtained in drill hole 84-52 which assayed 4.24 to 5.07 ppm Au over 0.33 m. The anomalous gold values were associated with sulphide mineralization. The diamond drilling program traced the anomalous chert horizon for approximately 150 m along strike (Assessment report 42E12NW0443).
