The Glenfiddich developed prospect is hosted in a stock of dioritic feldspar porphyry related to the Late Cretaceous Windy Table Complex. The prospect is located east of the confluence of Camp Creek and La Jaune Creek. Several outcrops indicate a steep, northeast striking planar zone of intense silicification (vuggy silica). The outcrop contains abundant vugs up to 50 centimetres across but not containing euhedral quartz.

The Glenfiddich Zone represents high sulphidation veins with silver-copper-gold mineralization present as vuggy silica, pyrite, tetrahedrite plus/minus chalcopyrite plus/minus enargite. The zone contains vuggy quartz veins crosscutting intense pyrophyllite plus/minus quartz plus/minus sericite plus/minus orthoclase alteration.

In 2013, drill hole THN13-121 intersected an upper zone of quartz-pyrite veining (formerly B Zone) and a lower zone of sulfosalt-pyrite mineralization corresponding to two faults. The entire hole contains intense pyrophyllite alteration.

In 2014, Glenfiddich drill hole THN14-125 intersected 66.90 metres grading 17.03 grams per tonne silver, 0.30 gram per tonne gold including 3.00 metres grading 70.97 grams per tonne silver, 2.13 grams per tonne gold (Figure 9, Assessment Report 35192).

In 2014, Brixton Metals established an inferred resource estimate, compliant with NI-43-101 standards of 21.5 million ounces of silver equivalent (7.4 million tonnes, grading 89.75 grams per tonne silver equivalent), for the Oban, Glenfiddich and Talisker zones combined (Assessment Report 35192). The Glenfiddich portion of the above combined total is 2.1 million tonnes grading 0.48 gram per tonne gold, 16.01 grams per tonne silver and 0.13 per cent copper (Assessment Report 35192, page 32).

Based on limited core review in 2018, mineralization in the Oban, Talisker and Glenfiddich zones are polymetallic (silver- gold plus/minus lead, zinc, copper) and related to heterolithic breccias (especially at the Oban Zone) and intermediate-to-high-sulphidation veins. Sulphide content commonly exceeds 5 volume per cent primarily as pyrite but with significant galena, sphalerite, tetrahedrite/tennantite, chalcopyrite and boulangerite. For the Oban, Glenfiddich and Talisker area, increasing copper toward the bottom of the deep hole THN13-119 has been noted previously. Selenium and tellurium show a pronounced southward gradient from the Oban holes toward and across Glenfiddich. Glenfiddich holes THN13-121 and 122 contain 2 to greater than 8 parts per million selenium and 3 to 20 parts per million tellurium (Assessment Report 38219). Talisker hole THN13-120 is also selenium and tellurium-anomalous but less so than the Glenfiddich holes. Possible interpretations for these findings are a deeper porphyry copper-gold centre possibly resides beneath Oban or a porphyry centre beneath or near the Glenfiddich holes.

Work History

In 2013, Brixton Metals drilled 35 diamond drill holes during a two-phase exploration program for a total of 6.078 metres at the Oban, Talisker and Glenfiddich zones, collected 1,368 soil samples and 13 rock samples, conducted a specific gravity survey on drill core, contracted SRK Consulting Canada Inc. to perform detailed structural analysis of the Thorn Property and carried out reclamation and physical work (Assessment Report 34506). Geochemical analyses resulted in doubling the extent of mineralization in the Oban diatreme breccia and near surface mineralization was drilled at the Glenfiddich Zone where 2.21 metres grading 583.05 grams per tonne silver, 10.62 per cent copper and 2.55 grams per tonne gold was intersected (Assessment Report 34506). In 2013 thirteen rock grab samples were collected for geochemical analysis from the Oban Zone area, the Glenfiddich Zone, and from south of La Jaune creek (G Zone?). Six were collected during phase two, with five collected as follow up on a high-grade soil anomaly along Camp Creek identified during phase one, and one collected from mineralized Oban breccia recently exposed due to a mudslide.

In 2014, Brixton Metals drilled 8 holes totalling 1,287.46 metres at the Outlaw zone and Glenfiddich, collected 16 soil samples and completed further reclamation and physical work. As a result of drilling 464 metres in 4 holes on the Glenfiddich, the zone was extended along strike and to depth. 2014 drilling expanded the strike of the zone and confirmed the historic drill results. All four holes intersected gold-silver mineralization.

In 2018 Brixton Metals Corporation examined and sampled intrusive and volcanic rocks from drill core and outcrop at the Chivas Zone (THN17-149); as well as drill core from select holes at the Oban (THN11-60 and THN13-119), Talisker (THN11-56) and Outlaw (THN14-128) zones in order to assess district-scale mineralization and metal zoning. The collection of 15 samples for petrographic analysis was carried out in order to document intrusive rock mineralogy and mineralization styles from Chivas, Oban, Talisker and Outlaw (104K 083).

In 2019, Brixton conducted geological mapping and soil and rock geochemistry at the Chivas zone expanding the porphyry target to 3 kilometres along strike which remains open. Brixton completed a 9.1 line-kilometre Induced Polarization-magnetotelluric survey across the Camp Creek copper corridor, which also contains the Oban diatreme breccia pipe and Glenfiddich zone. This survey showed a chargeability high over the Oban zone. Intersections of porphyry-style copper-gold-molybdenum mineralization in multiple 2019 drill holes in the Camp Creek Corridor targets:

THN19-150 (Oban): 554.70 metres at 1.97 grams per tonne gold equivalent (97.00-651.70 metres);

THN19-151 (Oban): 256.87 metres at 2.31 grams per tonne gold equivalent (100.18-357.05 metres);

THN19-162 (Glenfiddich): 230.82 metres at 0.27 per cent copper equivalent (323.00-553.82 metres);

THN19-163 (north of Oban near Camp Creek): 9.03 metres 0.29 gram per tonne gold, 2.87 grams per tonnes silver and 0.2 per cent zinc. (Press Release, Brixton Metals Corp., Dec.19, 2019). Drill hole THN19-163 was designed to test the high chargeability anomaly delineated by the fall 2019 TITAN 24 DCIP Survey conducted in the Camp Creek area. The hole intersected gold-silver-zinc mineralization, which is hosted mainly in a matrix rich diatreme breccia unit and consists of sulphides as disseminated or veins.

In 2020, Brixton Metals Corporation completed 3,025 metres of drilling within 16 core holes on the Central Outlaw zone and on the new West Outlaw zone. A total of 1473 rock samples and 5588 soil samples were collected throughout the Thorn property (Press Release, Brixton Metals Corp., Dec.15, 2020).

In June 2021, an updated mineral resource for the Glenfiddich openpit deposit was reported at 1 240 000 tonnes inferred grading 15.41 grams per tonne silver, 0.45 gram per tonne gold and 0.12 per cent copper (Burrell, H., Deiss, A.M. [2021-06-23]: Thorn Property NI 43-101 Technical Report Sutlahine River Area, British Columbia, Atlin Mining Division).
