Mineralization Comments

Nov 26, 2019 (Therese Pettigrew) - At the Dillman 1 and 2 gold showings, stripping revealed two quartz vein exposures which may be parts of a single structure. The veins both fill fracture/jointing controlled dilation zones, and both maintain a strike of 080 to 090 degrees despite containing a series of small open folds. The two veins are separated by about 100 metres of intervening ground where outcrop is sparse. Both showings are hosted within pillowed to massive mafic volcanics, and both display similar, varying degrees of oxidation and alteration of wallrock for a distance of up to 0.5 metres on either side of the vein. Wallrock alteration consists of variable silkification, chloritization, and a peculiar banding due to "gneissic" segregation of feldspar and mafic silicates. At the more easterly of the showings, a 5 to 20 cm wide quartz vein has been traced for a distance of about 38 metres. At both ends of the stripped area the vein disappears, and may be offset beneath relatively deep overburden. Grab samples of altered wallrock have returned gold values ranging from 0.002 to 0.081 oz/ton. Chip samples including wallrock and quartz have assayed from 0.002 to 3.043 oz/ton gold, most commonly returning values around 0.20 oz/ton. Chip and grab samples consisting solely of quartz have assayed between 0.001 and 8.837 oz/ton gold, with most values occurring between 0.20 and 0.75 oz/ton. At the westerly showing, a 5 to 45 centimetre wide quartz vein has been traced for a distance of about 20 metres along strike. At both ends of the stripped area, the vein appears to pinch out against northeasterly-trending zones of shearing, at the edge of areas covered by relatively thick overburden and jumbled bedrock. Assays here ranged between 24 ppb and 1366 ppb (0.033 oz/ton) gold for altered wallrock, with most values below 100 ppb (0.003 oz/ton). Representative samples across the altered wallrock and vein returned values ranging from 713 ppb (0.023 oz/ton) to 0.431 oz/ton gold. Grab and chip samples consisting entirely of quartz returned assays ranging from 0.03 to 2.822 oz/ton gold, with most assays falling between 0.30 and 0.70 oz/ton (Assessment report 52F04SW0001).
