Mineralization Comments

Jun 29, 2020 (Therese Pettigrew) - Both the North and South showings are shear zone hosted and are located at either end of a metadiorite intrusion. Graham Bousquet personnel traced the northern showing for a distance of 61 m with an average width of 0.61 m. Here quartz veining, pyrite, arsenopyrite and sparse chalcopyrite were encountered but only grab samples containing arsenopyrite contained significant gold values of up to 0.30 ounce per ton. Four X-ray diamond drill holes (134.1m) sunk under the northern showing encountered massive and silicified andesite, feldspar porphyry, diorite and chert with "augen flow structures" which are interpreted to be felsic spherulitic flows. Only sparse pyrite was encountered in the drill core and no assays higher than 0.01 ounce gold per ton were returned. At the northern showing gold is more likely to occur in sulphide rich altered wallrock than in quartz veins or sulphide poor wallrock within the shear zone. Traverses by the 1987 OGS field crew in the area around the north showing located several additional east-northeast trending shear zones within the metadiorite pluton, many of which are silicified. One area of potential economic interest occurs approximately 300 m west-southwest of the pits. Here extensive quartz veining, pervasive silicification, carbonitization and tourmalinization with up to 10 percent pyrite occurs in massive to sheared quartz diorite. Samples collected by B. Berger returned less than 2 ppb gold, up to 18 ppm arsenic and up to 525 ppm tungsten (288-289A). A sample of similar material 128 collected by L. Chorlton (geologist, Ontario Geological Survey) returned 230 ppb gold when assayed. Scheelite was identified by means of an ultraviolet lamp in sample 289A (Berger, 1989). A grab sample from the 1996 program by Corona returned 0.227 opt Au. Also along the north mineralization trend, grab samples collected in 1990 by A. Glatz returned 10.83 g/t Au and 21.74 g/t Au (Assessment report 52F16SW2003)
