Chairman and CEO Gary R. Thompson Stated, “We are very excited about the new discoveries that were made at the Thorn Project in 2021. This season is shaping up to be transformative for Brixton as we continue to demonstrate the potential of this emerging copper-gold porphyry belt within the 2600 square kilometer, wholly owned Thorn Project. We plan to be drilling multiple large-scale targets with a minimum of 2 drills turning all season.”
Camp Creek Copper Porphyry Target
Brixton Metals made significant progress in 2021 on the blind Camp Creek Copper Porphyry Target. A total of 2662.78m of core was drilled with THN21-183 being the deepest hole on the property. Drill holes 162, 181,183 and 184 show copper, gold, silver and molybdenum grades, as well as porphyry index values (MPIx), increasing with depth and ending in mineralization. The bottom of holes 183 and 184 are approximately 286m apart.

Collaborators at UBC’s Mineral Deposit Research Unit (MDRU) identified four geochemically distinct porphyry phases, with “porphyry X” being the primary mineralized unit. Porphyry X is a crowded plagioclase porphyry of Cretaceous age, characterized by well-defined stacked biotite, a feature typical of mineral-related porphyry phases. Mineralization is also hosted in Triassic Stuhini Group sedimentary rocks, which are intruded by the porphyry phases. Radiometric dating of these porphyries using the U-Pb zircon method showed they were emplaced approximately 85 million years ago, confirming an age similar to the Pebble copper-gold-molybdenum deposit in southwest Alaska. The reference to Pebble is important because pre-faulting architecture by Goldfarb et al. (2013) place Thorn inboard of Pebble during deposition and that about 1100km of dextral displacement has occurred post accretion, moving Pebble to where it is located today. MDRU conducted short-wave infrared (SWIR) analyses and interpretation. The SWIR analyses indicate higher temperatures towards the west-northwest, please see Figure 2 below.

The Camp Creek porphyry mineralization is thought to have a footprint of about 1km by 2km based on the surface expression of several different high-sulphidation mineralized zones including the Talisker and Glenfiddich Zones and the Oban Diatreme Breccia Zone.
The aim of the 2022 drilling at Camp Creek will be to test for the high-grade core of this copper dominant porphyry system with 4 to 6 deep holes with the aid of drill-wedges.
The Trapper Gold Target
The Trapper Gold Target was a major focus of the 2021 season. Following the 2020 acquisition of the Trapper claims and royalties, this was the first full exploration season conducted by Brixton which successfully highlighted the gold endowment of the target.
Brixton drilled 15 holes for a total of 3107.34m. Standout holes include THN21-186 that reported 139.00m of 2.14 g/t Au including 11.5m of 19.25 g/t Au and THN21-195 with 84.00m of 1.1 g/t Au. Table 1 below provides the 2021 Trapper drill results, including the balance of the 2021 Trapper drill results not previously released.
The Trapper Target consists of volcanic and volcaniclastic rocks of the Upper Triassic Stuhini group, which are intruded by Cretaceous quartz diorite, interpreted as part of the Thorn Magmatic Suite. The quartz diorite is associated with high-grade gold mineralization at Trapper, including a broad gold zoning that extends into the Stuhini volcanic rocks.

Geochronology was completed at Trapper yielding an age date from U-Pb Zircon method of 85.2 ± 1.2 Ma for the quartz diorite, the primary lithology which hosts gold mineralization. This Cretaceous age date is contemporaneous with the porphyry host rocks at Camp Creek Porphyry Target. Terrane Geosciences was contracted to conduct a structural mapping in the area, please see Figure 3 below. At surface, soil and rock geochemistry outline a 4km north-northwest gold trend and up to 1.5km in width with 2021 rock grab samples assaying up to 135.5 g/t Au. Gold-in-soil values have a strong positive correlation to lead and zinc. Several new copper-gold-silver showings were discovered outside the Trapper Gold trend in 2021 with values up to 23.5 g/t Au and 5.2% Cu.

Trapper will be a primary drill target for the 2022 season including 10,000-15,000m of drilling, with additional mapping, geochemical and geophysical surveys.
Outlaw Gold Target
The Central Outlaw Target is located more than 3km to the southeast from the Camp Creek Target. Gold Mineralization is hosted with clastic sediments as Triassic Stuhini group interbedded siltstone-graywacke where a gold-in-soil anomaly is about 5km long in an east-west trend. Mineralization is stratiform and within structural controlled areas and is thought to be to related to Jurassic dacite dykes that intrude the sediments. The Central Outlaw Zone has seen most of the drilling to date providing a continuous strike of 600m with drill results up to 59m of 1.1 g/ Au. The highest surface rock grab sample was from the East Outlaw area returning 22.98 g/t Au. Please see Figure 4 below for the gold-in-soils and the Central and East Outlaw drilling and rock sample results.
The plan at the Outlaw Target in 2022 is to drill for continuity and extension of gold mineralization between the Central and East Zone through 4-6 widely spaced drill holes.

Metla Copper-Gold Porphyry Target
Metla is a copper-gold porphyry anomaly within the Thorn Project and is located about 15km to the Southeast from the Trapper area. The Metla claims were acquired in 2020 from Stuhini Exploration. Major rock units at Metla include sedimentary and mafic- to ultramafic-intrusive rocks of the Stikine assemblage, volcanic and volcaniclastic rocks of the Stuhini Group, Late Cretaceous to Paleocene felsic intrusive rocks, and hydrothermal breccia dykes that crosscut all of the previous units. Recent U-Pb zircon age dating indicates that the Au-Cu bearing granodiorite is Triassic in age, 220 +/- 3.1 Ma. Several distinct styles of mineralization occur in the Metla area including potassic altered diorite unit with bornite, chalcopyrite and chalcocite that returned 4.7% Cu, 1.8 g/t Au, 31 g/t Ag. Showings of massive pyrite, chalcopyrite and sphalerite are hosted in the hydrothermal breccia where rock samples have returned up to 62.7 g/t Au and 4.54% Cu. A 1989 trench by Cominco returned 9m of 4.6 g/t Au.
The 2022 exploration program will include extensive geochemistry, geological mapping and airborne radiometric and electrical geophysical surveys over the Metla target and will be used to define drill targets.

Plum Copper Target
The Plum Target is located 8 km east of the Metla Target, immediately west of Tatsamenie Lake. The geology is dominated by Mississippian volcanic rocks of the Stikine assemblage, with local Lower Permian limestone. The aforementioned rocks are intruded by Triassic and Jurassic diorites and Eocene mafic dykes. Copper mineralization is vein-hosted with chalcopyrite and pyrite, including local chalcocite. This mineralization is found within broader zones of silica and pyrite alteration. Grab samples collected in 2020 found multiple occurrences with greater than 1% Cu, including one rock grab sample assay of 3.32% Cu.
Follow-up prospecting, mapping and soil-rock sampling is planned for 2022.

East Copper Porphyry Target
The East Target is located 25km east of Metla and 17km north-northeast of the Golden Bear Mine. The geology is dominated by Middle to Late Triassic quartz diorite and granodiorite intrusive rocks, with windows of Stuhini Group volcanic rocks. There are two main copper showings on either side of the Samotua River. The Ant showing is to the west and includes a 2km x 0.8km gossan with associated copper soil anomaly. Copper values in rocks reach up to 3.62% Cu and have not yet been drill tested. The Bing showing is on the east side of the river and includes widespread copper +/- molybdenum mineralization as disseminations and within porphyry style veining stockworks. Limited historic drilling here did not target the area hosting the most anomalous samples. Surface rock grab samples have returned up to 5.15% copper and 145 g/t silver.
Follow up mapping and rock-soil sampling are planned for 2022.

West Copper Porphyry Target
The West copper target is located 5km west-southwest of the Camp Creek Target. Geology at the West Target is comprised of Triassic volcanic rocks of the Stuhini Group, and Jurassic argillite and conglomerate of the Laberge Group. These Mesozoic volcanic and sedimentary rocks are cut by an Eocene granite (54.2 +/- 0.8Ma) and alkali feldspar granite batholith of the Sloko-Hyder Plutonic suite, some of which has been locally metamorphosed. Mineralization is vein-hosted and disseminated, with porphyry-style quartz-pyrite-chalcopyrite veins in the Eocene intrusive and Stuhini volcanic rocks. A float sample collected in 2020 assayed 4.27% Copper.
Follow-up mapping and rock sampling are planned for 2022.

South Gold-Copper Target
The South Target is located approximately 35 km south of the Trapper Target. Geology includes greenstones of the Whitewater Metamorphic Complex, coarse clastic sedimentary rocks of the Stikine Assemblage and Late Triassic quartz diorite intrusive rocks. Known mineralization includes vein-hosted chalcopyrite and disseminated pyrite and chalcopyrite, although only reconnaissance geochemistry surveys have been completed in the target area to date. The target includes one of the highest-grade gold samples in silts from the BC Regional Geochemical Survey, with 990.7 ppb Au and elevated Cu-Ag-As. This RGS sample is one of the highest in BC. For reference, the highest RGS value in the entire KSM-Brucejack-Treaty area is 618 ppb and the highest RGS value in the Golden Triangle is 1,087 ppb Au at Johnny Mountain.
Follow up soil-rock geochemical surveys, prospecting and recon-mapping are planned for 2022.
