Lithology

Lithology Comments

May 27, 2016 (A Wilson) - The hole was collared beneath some 37 m of overburden in brecciated dacitic tuff in which at least 2 low grade auriferous quartz-carbonate veins occur. The attitude of any fault related to this breccia is not known. It may be part of the Barnet Creek Fault Zone. However similar bad ground conditions caused by breccia were described in the R.C. overburden drill holes 150 m northwest of DDH 98 ME-01. Hence it is possible that the drilled area is at or near the intersection of two fault systems. These could be the north-south Barnet Creek Fault Zone and possibly a northwest system in the trough near the Kinojevis-Blake River contact. This hole and the preceding holes on the west side of Barnet Creek define a wide zone (approximately 500 m) of hydrothermal alteration within which low grade auriferous quartz carbonate veins have been found. Whether or not veins containing ore grade gold values occur in this target area can only be determined by additional drilling.

Mineralization

Mineralization Comments

May 27, 2016 (A Wilson) - In the far north of the survey area, overburden drill holes 81-08, 81-22, and 81-23 carry strong Au values in the basal till. DDH 81-23 returned a best sample of 10,000 ppb Au over 1 foot (76.0 to 77.0 ft.). The highest Au analysis, 173 ppb Au, was obtained in sample 25122 from 80.77 - 81 .84 m depth. This zone is dominated by high alteration and shearing, 30º calcite veins and quartz-calcite veins and 2%-3% pyrite as 3 mm seams. Note that the sludge from this section contained 43 ppb Au. This sample is also anomalous in Cd (1 .1ppm) and is enriched in Pb (46 ppm). Anomalous Au (31 ppb) was also found in sample 25136 from 167.58 -169.10 m. This zone is marked by abundant hematized quartz-calcite veins with up to 1% disseminated pyrite. This sample is also anomalous in As (25 ppm), Cd (1.3 ppm) and Sn (20 ppm). Sludge was not recovered from this part of the hole. The best assay from DDH 92ME-01 assayed 0.17 g/t Au over 1.1 m. Drill hole 98ME-01 was collared in a major fault zone in dacitic tuff in which three gold-bearing quartz carbonate veins were encountered. Assay values for gold were 0.4 g/t over 2 m and 0.42 g/t over 0.75 m and 0.2 g/t over 1 m. The hole exhibited hydrothermal alteration (carbonate, silica and hematite) throughout its full length of 224 m. The source of the gold in the till anomalies is believed to be auriferous quartz-carbonate veins within the Barnet Creek Fault Zone. Additional drilling is recommended to help define a potential economic source of gold. From this and previous drill programs it is concluded that the gold in basal till anomalies on the claim group are related to auriferous quartz carbonate veins. The structural controls could be the Barnet Creek Fault Zone and intersecting northwest trending faults.
