Chivas Gold Zone Project Summary

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.
  • No previous drilling was done prior to 2017 in the area.

2017 Summary: Phase One

Brixton completed ten NQ-sized core drill holes for a total of 2,455 metres at the Chivas Zone. Drilling at the Chivas Zone was designed to test the gold-in-soil anomaly identified in 2016. The gold-in-soil anomaly at the Chivas Zone covers a 7 square kilometre area and has corresponding chargeability anomalies from the 2016 Titan-24 DC/IP survey. In 2017 Brixton collected 517 soil and 56 rock samples throughout the property and completed two weeks of 1:2500 and 1:5000 scale geological and alteration mapping at the Chivas Zone. Aerial Lidar was conducted over a 210 square kilometre area. Brixton expanded its claim group from 996 square kilometres to 1,114 square kilometres.

Thorn Project 2017 drill results are pending at this time.

Thorn Project Soil Results

Using a 100 ppb cut off for the soil results, 69 samples are greater than 100 ppb Au, 44 samples are greater than 200 ppb, 28 samples are greater than 400 ppb, 12 are greater than 800 ppb with the two highest samples being 4,900 and 6,920 ppb Au.

Geological Mapping at the Chivas Zone Identifies a New Copper Trend at Thorn

Mapping was successful in identifying a 115m by 1200m open-ended corridor of copper mineralization with up to 1.14% Cu and 2.15 g/t Au from surface rock sampling. The best values from rock grab samples were 4.49 g/t Au, 4.38% Cu and 443 g/t Ag.

Mineralization is dominantly hosted by quartz-carbonate-py+/-galena-sphalerite-sulphosalt veins and polyphase breccias cutting Stuhini Group volcanic rocks and is interpreted as being related to an epithermal system transitional to a Cu-Au-Mo porphyry system.

Geology was mapped by Marcus van Wermeskerken, B.Sc., he stated “there is a fairly well developed zoning in both alteration and mineralization, centered on the main porphyry intrusion. Starting at the centre, there is a distinct trend along which a porphyry type mineralization exists as disseminated chalcopyrite, malachite, quartz stockwork zones with sericite. Outwards from this core, there is a zone of scattered polymetallic veins and fault breccias, hematite, chlorite, epidote and patchy potassic alteration. This alteration-mineralization was measured on one side of the cuprous corridor for 600 metres. This suggests there was a significant heat pump at the time of mineralization. This is only at the very apex of what could potentially be a much larger intrusion below. A significant amount of epithermal type mineralization (polymetallic veins, chalcedony veins-breccia and argillic alteration zones) was noted, which is typical in the periphery of porphyry systems, suggesting potential for a mineralized system below.”

A reconnaissance soil line in a new area 2.7 kilometres south from the southern end of the Chivas Zone returned  an anomalous copper-in-soils area with a single rock sample returning 4.38% Cu and 0.8 g/t Au (see map).


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 boundary was mapped in the area of the gold anomaly.


The Company collected a total of 1,306 soil samples during 2016 at the Chivas Zone returning a high of 6,700 ppb Au. 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 in a NW/SE trend and up to 2.0 km wide and remains open.

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.
