There was no reported work at the Chivas Gold Zone until 2014, when Thompson and Posescu ran a single 700 m long soil line on a break in slope in the area. Most of the soil samples returned highly anomalous gold values with a high of 11.00 ppm Au, 12.70 ppm Ag and 11.4 ppm Te. During 2016, a large soil sampling program was completed and the Chivas Zone now represents the largest gold-in-soil anomaly on the property of greater than seven square km (3.5 km x 2 km). In addition, Brixton conducted geological mapping and contracted Quantec to survey 15.5 km of Titan24 DC/IP geophysics over the Chivas Zone.
The Chivas Gold Zone is a new large scale multi-million ounce gold target that is drill ready:
- First exploration work in 2014 returned up to 11 g/t Au (soil-talus fines).
- 7 km2 (gold-in-soil + IP high) anomaly and is open to the NW/SE.
- 2016 work included 1306 soils and 15.5km of IP geophysical work and mapping.
- Soil-fines returned up to 16.7 g/t Au in 2016.
- Au-Te-Cu-Ag geochemical signature hosted in Stuhini volcanics.
- Cripple Creek type Au-Ag-Te Epithermal and intrusion-related vein/disseminated type: Golden Mile Kalgoorlie WA (Au-Te-Ag), Timok in Serbia (Tethyan Cu-Au, Bi-Te belt), Bi-Te, Emperor-Tuvatu, Fiji (Au-Te).
- No drilling to date in the area.
The Chivas Zone is dominated by Upper Triassic Stuhini Group mafic volcanics. Two diorite intrusive units that cut the Stuhini rocks were mapped in the area during 2016. These intrusions were not previously recognized. The red-line unconformity was mapping on the western margin about 800 m west of the new large gold anomaly.
The Company collected a total of 1,306 soil samples during 2016 at the Chivas Zone. Results have delineated a substantial 7 km2 gold-in-soil anomaly at the Chivas Zone with a predominant northwest trend. The strike length of the anomaly is 3.5 km long and up to 2.0 km wide and remains open to the NE and SE. Using a 100 ppb cut off for the soil results, 478 samples are greater than 100 ppb Au, 257 samples are greater than 200 ppb Au, 132 samples are greater than 400 ppb Au, 53 samples are greater than 800 ppb Au and 2 samples are greater than 10,000 ppb with the two highest being 14,800 and 16,700 ppb Au.
In 2016, Brixton contracted Quantec Geoscience to run an IP survey over the Chivas area. The IP survey was conducted over 15.5 km of Titan24 DC/IP dipole-dipole array. The seven survey lines were orientated in a north-south direction at 300 m spacing with 50 m stations. The IP survey at the Chivas Zone succeeded in identifying a strong near surface chargeability high anomaly with a 2.4 km strike length and up to 1.8 km in width. The chargeability anomaly is open to the NW/SE and at depth.
