2017 Thorn Gold-Silver Project, British Columbia
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. Please see map at the link:http://brixtonmetals.com/wp/wp-content/uploads/2016/12/Chivas-Geology-NR-A2017.jpg
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 link to map above).
About the Chivas Gold Zone (Thorn Project)
The Chivas Gold Zone was first identified in 2014 when the Company collected 16 soil samples along a break in slope where 12 of the 16 samples where anomalous (above 30 ppb Au) in gold with a high of 11,000 ppb Au was found. There was no previous work reported from this area of the property and this zone represents an important new mineralized target. The Chivas Zone is located about 3 kilometres southwest from the western edge of the sediment hosted Outlaw Gold Zone where hole 128 intersected 59.65m of 1.15 g/t Au, 5.64 g/t Ag, and about 4 kilometres south from the silver rich Oban Diatreme Zone where hole 60 intersected 95m of 628 g/t Ag and 1.71 g/t Au. Host lithology to mineralization at the Chivas Zone is Triassic Stuhini group mafic volcanics. The 7 square kilometre gold-in-soil anomaly and the IP chargeability anomaly clearly define an open-ended northwest trend. The red-line boundary (Triassic-Jurassic unconformity) was mapped about 800 metres west of the Chivas anomaly. According to Kyba and Nelson of the BCGS, most major deposits in northwestern BC, including KSM, Brucejack and Eskay Creek, occur within 2 km of this regional red-line marker, which implies major regional-scale faults as metal-rich fluid pathways.

2017 Atlin Gold Project, British Columbia
Results from 26 rock samples returned a high of 24 g/t Au. Twelve of the 26 samples were greater that 0.1 g/t Au. The samples were collected in the vicinity of historic trenches on the LD claims; however, at the time of sampling the trenches were reclaimed and filled in. Brixton conducted an airborne magnetic survey of eight flight lines covering a total of 4,571 line kilometres of high resolution magnetic data. The traverse lines were flown East-West at a spacing of 200 metres with control lines flown North-South at a separation of 2000 metres. Nominal terrain clearance was specified at 100 metres above ground. Compilation of historic data and interpretation of the airborne magnetic survey is ongoing. Please see link to the Map showing the LD claims:
Historical work on the LD claims includes 330 g/t Au (mini-bulk sample), 1,615 g/t Au (rock grab sample) and 3m of 9.39 g/t Au (drill core). Brixton’s land package in the Atlin gold camp offers large target areas for exploration in search of Barkerville style or California style mother-lode gold deposits that may exist in prospective host rocks that are masked by overburden.

2017 Langis-Hudson Bay Ag-Co Project, Ontario
Historical data compilation continues for the Langis area. Following the acquisition of the Penna lands from Agnico at the Langis site, four rock grab samples from the Penna #7 shaft dump area were submitted for analysis. The table below provides details which returned up to 18% silver and 16% Cobalt. Samples contained abundant native silver.
