Chairman and chief executive officer Gary Thompson stated: "Classic boots on the ground work continues to identify new mineralized outcrop on a regular basis on the Thorn project with lots of ground yet to cover. We are looking forward the completion of the 2023 geochemistry program aiding in new drill targets for next season."

2023 summary

The 2023 exploration season on the Thorn project started mid-May and continues, with surface geochemical sampling being conducted across multiple target zones to date. Regional fieldwork has been focused on advancing early-stage exploration targets such as the Metla, North and Bing targets with the goal of generating drill-ready targets for the 2024 field season. Additionally, reconnaissance geochemical sampling has also been completed on multiple regional exploration target areas across the 2,863-square-kilometre project to test new areas for potential porphyry and epithermal style mineralization. While the majority of 2023 assay results are yet to be received, highlights from initial assay results are reported herein for the Metla, West, North, Bing and Trapper targets.

West target

The West target is located approximately five km southwest of Thorn Camp and six km west of Brixton's Camp Creek Cu-Mo-Au porphyry target and hosts significant copper-silver mineralization. Assay results from 2023 surface rock grab samples have returned 18 samples greater than 1.0 per cent copper, including 11 samples greater than 5.0 per cent copper. Highlights from recent assays include, 16.7 per cent copper and 327 g/t Ag from sample D200955, 16.3 per cent copper and 817 g/t Ag from sample D200956, as well as 16.2 per cent copper and 725 g/t Ag from sample D200326 sampled from semi-massive quartz-base metal sulphide veins hosted in a propylitic altered quartz-hornblende diorite. Additional work is continuing at West target to further define the extents of the mineralization and determine the potential for porphyry copper mineralization in the area.

Metla target

The Metla target claims were acquired by Brixton in 2020 and is an early-stage porphyry-epithermal target located 25 km southeast of Thorn camp. A large geochemical sampling program completed in 2022 field season returned significant assay results for both gold and copper. See NR dated Jan. 23, 2023. Fieldwork in 2023 has focused on expanding upon 2022 results and highlights from initial assay results are listed in the second attached table, including 52.5 g/t Au and 51.7 g/t Au from surface samples D200670 and D200671 collected form polymetallic quartz veins hosted in a foliated quartz-diorite. Additional results include 4.5 per cent Cu and 3.8 per cent Cu from samples D200674 and D200609 collected from quartz-pyrite-chalcopyrite veins. Geological mapping and geochemical sampling are continuing across the Metla target which continue to broaden the copper-gold mineralized footprint and scale potential in this area.

North target

The North target is located approximately 10 km north of Thorn camp and is actively being explored for its porphyry Cu-Mo-Au potential. The target hosts a similar geological setting to the Camp Creek porphyry target. Surface rock, soil and talus fines samples have been collected over a 60 square km area, expanding upon historic work and testing new areas to help focus future exploration efforts including geological mapping.

Bing zone-East target

The Bing zone is approximately an 18 square km area within the East target located 50 km southeast of Thorn camp and was recently acquired by Brixton in 2022. Historic work on the target included geological mapping, surface geochemical sampling and diamond drilling which had identified a broad area of porphyry-copper style mineralization. As the majority of Bing has limited outcrop, fieldwork has focused on extending soil sampling grids to help define focus areas for exploration. Recent and historic soil sampling has identified a three by four km area of anomalous copper mineralization with high porphyry index indicator elements.

Trapper gold target

The Trapper gold target is an intermediate-sulphidation epithermal target and has been one of the main focus areas for drilling since 2021. The 2023 drill program has been continuing since late-June targeting larger stepout areas as well as more proximal infill stepouts to the main mineralized zone. While 2023 drill hole assays are pending, some initial surface rock grab samples have been received. The majority of 2023 fieldwork at Trapper has focused on sampling areas outside of the main drilling zone to assist future drill targeting as well as test nearby areas for a potential porphyry-related source to the Trapper mineralization. Highlights from initial assays received to date are listed in the third attached table and include 19.9 g/t Au, 138 g/t Ag and 0.2 per cent Cu from sample D200444 and 15.2 g/t Au and 23.8 g/t Ag from sample D200287.

Rocks collected are select grab samples of mineralized outcrops within each of the target areas and do not represent the entire target.

Vice-president of exploration, Christina Anstey, stated, "We are very encouraged to see the positive initial results from our 2023 geochemical sampling programs across many of our regional exploration targets and we look forward to completing additional follow-up work and receiving the bulk of the assay results expected in the months to come."

Rock samples were prepared by ALS Minerals preparation facility in Whitehorse, YT, and assayed at ALS Laboratory Facilities in North Vancouver, B.C. ALS Minerals Laboratories is registered to ISO 9001:2008 and ISO 17025 accreditations for laboratory procedures. Samples were analyzed for gold by fire assay with an atomic absorption finish, whereas Ag, Pb, Cu and Zn, and 48 additional elements were analyzed using four-acid digestion with an ICP-MS finish.

2023 Thorn project regional exploration targets

While the main focus for 2023 as been on high-priority target definition, additional fieldwork has been conducted across multiple target zones including the South, Central, Moly Valley, Icy and Val targets, as well new target areas that have seen limited or no previous exploration work on the Thorn project. Assay results are pending for the majority of surface geochemical sampling and the 2023 drilling and fieldwork programs are projected to continue until early to mid-October. Brixton aims to advance its current drill targets while developing the project-wide district scale potential for mineralized deposits related to porphyry and epithermal environments at Thorn.

About the Thorn project

The wholly owned 2,863-square-kilometre Thorn project is located in northwestern British Columbia at the northern trend of the Golden Triangle, Canada, approximately 90 km northeast of Juneau, Alaska. The Thorn project hosts a district-scale 80 km megatrend of Triassic to Eocene, volcano-plutonic complex with several styles of mineralization related to porphyry and epithermal environments. Fourteen large-scale copper-gold targets have been identified for further exploration.

Quality assurance and quality control

Quality assurance and quality control protocols for drill core sampling were developed by Brixton. The gold, silver, copper, lead, zinc and molybdenum duplicate assay results are well correlated, and it is the qualified person's opinion that strong precision is inferred within the reported analytical results. Core samples were taken between 0.5 m and 2.5 m intervals based on lithology and mineralization. Blank, duplicate (lab pulp) and certified reference materials were inserted into the sample stream for at least every 20 drill core samples. Core samples were cut, bagged, zip-tied and sent directly to ALS Minerals preparation facility in Whitehorse, Yukon. ALS Minerals Laboratories is registered to ISO 9001:2008 and ISO 17025 accreditations for laboratory procedures. Samples were analyzed at ALS Laboratory Facilities in North Vancouver, B.C., for gold by fire assay with an atomic absorption finish, whereas Ag, Pb, Cu and Zn, and 48 additional elements were analyzed using four-acid digestion with an ICP-MS finish. The 2022 Thorn project analytical results have been determined to be high quality and have passed this QA/QC review.

The standards, certified reference materials, were acquired from CDN Resource Laboratories Ltd., of Langley, B.C., and the standards inserted varied depending on the type and abundance of mineralization visually observed in the primary sample. Blank material used consisted of non-mineralized siliceous landscaping rock. A copy of the QA/QC protocols can be viewed at the company's website.
