Brixton Metals Reports Up to 96.9% Gold Recovery and 97.3% Copper Recovery from Three Zones of the Camp Creek Porphyry-Epithermal System

Brixton’s Camp Creek metallurgical tests show high gold and copper recoveries across all zones.

What the company is saying

Brixton Metals Corporation (TSXV:BBB, OTCQX:BBBXF) is reporting initial scoping-level metallurgical results from the Camp Creek system at its wholly owned Thorn Project in British Columbia. The company emphasizes that all three main mineralization styles—Porphyry X, Oban Breccia, and high-sulphidation veins—responded well to conventional gravity and rougher flotation, with gold recoveries up to 96.9% and copper rougher recoveries above 97%. Gary R. Thompson, Chairman and CEO, frames these results as a key step toward the maiden Mineral Resource Estimate (MRE), expected in Q1 2027, and highlights the scale and vertical zoning of the system. The announcement stresses the technical rigor of the testwork, referencing independent analysis by SGS Canada Inc. and detailed QA/QC protocols. The company also signals that further metallurgical work, including cleaner flotation and assessment of lead, zinc, and antimony, will follow. The tone is confident and data-driven, focusing on recoveries, grades, and the upcoming resource estimate rather than speculative economic projections.

What the data suggests

The disclosed metallurgical results show gold recoveries between 88.8% and 96.9% and silver recoveries from 88.2% to 95.7% across three mineralization styles. Porphyry X composite achieved 97.2% copper, 88.4% molybdenum, and 88.3% gold recoveries, with a rougher concentrate grading 3.20% Cu, 0.32% Mo, 2.05 g/t Au, and 43.7 g/t Ag. The Oban Breccia composite returned 93.1% gold and 93.9% silver recoveries, with a rougher concentrate grading 9.94 g/t Au, 2,966 g/t Ag, and 2.30% Cu, and a copper rougher recovery of 97.3%. High-sulphidation veins composite delivered 96.9% gold and 95.7% silver recoveries, with gravity concentration alone recovering 6.0% of the gold into a 279 g/t Au concentrate. Historical intercepts include 554.70 m of 0.57 g/t Au, 43.18 g/t Ag, and 0.24% Cu (Oban Breccia, THN19-150) and 967.71 m of 0.25% Cu, 0.09 g/t Au, 2.39 g/t Ag, and 186 ppm Mo (Porphyry, THN22-201). Copper equivalent calculations use US$4.75/lb Cu, US$3,500/oz Au, US$50/oz Ag, US$20/lb Mo, and recoveries of 97.1% Cu, 92.9% Au, 92.6% Ag, and 73.0% Mo. The technical data is comprehensive for an early-stage metallurgical program, but no economic or resource figures are provided yet.

Analysis

The announcement is a technical update on initial metallurgical testwork at the Camp Creek system, providing detailed and specific recovery and grade data for three mineralization styles. The majority of claims are realised and supported by explicit numerical results (e.g., gold and silver recoveries, head grades, and drill intercepts). Forward-looking statements are limited to the next phase of testwork and the timeline for the maiden Mineral Resource Estimate (MRE), expected in Q1 2027, which is more than a year away. There is no evidence of exaggerated or promotional language; the tone is proportionate to the technical results disclosed. No large capital outlay or immediate earnings impact is discussed, and the operational update is appropriate for an exploration-stage company. The only minor inflation is the qualitative phrase 'responded well,' which is not benchmarked, but this does not materially affect the overall signal.

Risk flags

• ●The project remains at an early stage, with only initial metallurgical testwork and no resource estimate or economic assessment yet completed. This means there is significant uncertainty about the ultimate size, grade, and economic viability of the deposit.
• ●The timeline to the maiden Mineral Resource Estimate extends into Q1 2027, introducing execution risk related to further drilling, testwork, and potential delays in resource modeling or permitting.
• ●Metallurgical recoveries, while high in scoping-level tests, may decrease in subsequent cleaner flotation stages or at larger scale, and the company acknowledges that final recoveries are typically lower than rougher-stage results.
• ●The presence of elevated lead, zinc, and antimony—especially in the Oban Breccia—may complicate concentrate quality or processing, and deportment of these elements has not yet been fully assessed.
• ●No financial, cost, or capital intensity data is provided, so investors cannot yet assess the potential economic return or funding requirements for advancing the project.

Bottom line

Brixton’s initial metallurgical results from Camp Creek at the Thorn Project show strong gold and copper recoveries across all tested mineralization styles, with gold recoveries up to 96.9% and copper rougher recoveries above 97%. These technical results are encouraging for the potential of the system but remain early-stage, with no resource estimate or economic study yet available. The next major milestone is the maiden Mineral Resource Estimate, targeted for the first quarter of 2027, and further metallurgical work is needed to address concentrate quality and the impact of secondary metals. Investors should see this as a positive technical update but recognize that value realization is long-term and subject to significant execution and geological risk. The most important takeaway is that Camp Creek demonstrates promising metallurgy, but the project’s scale, economics, and timeline to production remain unproven.

Announcement summary

(TSXV:BBB, OTCQX:BBBXF) Brixton Metals Corporation announced initial scoping-level metallurgical testwork results from the Camp Creek system at its wholly owned Thorn Project in NW British Columbia, Canada. The company tested three composites representing the main mineralization styles at Camp Creek: Porphyry X (copper-molybdenum-gold porphyry at depth), the near-surface Oban Breccia, and high-sulphidation gold-silver-copper veins of the upper Camp Creek system. All three composites responded well to conventional gravity concentration and rougher flotation. Combined gravity and rougher flotation gold recoveries ranged from 88.8% to 96.9%, and silver recoveries ranged from 88.2% to 95.7%. The Porphyry X composite (0.52% Cu, 0.22 g/t Au, 519 ppm Mo) achieved rougher flotation recoveries of 97.2% copper, 88.4% molybdenum, and 88.3% gold into a rougher concentrate grading 3.20% Cu, 0.32% Mo, 2.05 g/t Au, and 43.7 g/t Ag, for an overall gold recovery of 88.8%. The Oban Breccia composite (3.77 g/t Au, 1,280 g/t Ag, 0.93% Cu) achieved overall recoveries of 93.1% gold and 93.9% silver, with a rougher concentrate grading 9.94 g/t Au, 2,966 g/t Ag, and 2.30% Cu, and a copper rougher recovery of 97.3%. The high-sulphidation veins composite (3.44 g/t Au, 148 g/t Ag, 0.77% Cu) achieved overall recoveries of 96.9% gold and 95.7% silver; gravity concentration alone recovered 6.0% of the gold into a concentrate grading 279 g/t Au. The Camp Creek system has a history of wide, well-mineralized intercepts, including 554.70 m of 0.57 g/t Au, 43.18 g/t Ag, and 0.24% Cu in the Oban Breccia (THN19-150), and 967.71 m of 0.25% Cu, 0.09 g/t Au, 2.39 g/t Ag, and 186 ppm Mo in the porphyry (THN22-201). Copper equivalent (CuEq) was calculated using US$4.75/lb Cu, US$3,500/oz Au, US$50/oz Ag, and US$20/lb Mo, and recoveries of 97.1% Cu, 92.9% Au, 92.6% Ag, and 73.0% Mo. The Oban Breccia and high-sulphidation veins rougher concentrates carried 40.2% and 46.9% of the feed mass, respectively, reflecting head sulphur grades of 12.0% and 17.2%. The next phase of testwork will include cleaner flotation to reject sulphide and upgrade the concentrates, and will assess the deportment of lead, zinc, and antimony. The results will be incorporated, with the 2026 drill results, into the maiden Camp Creek Mineral Resource Estimate (MRE), which is being prepared with APEX Geoscience Ltd. and is expected in the first quarter of 2027. Gary R. Thompson, Chairman and CEO, stated that the initial metallurgical results show each mineralization style responds well to a conventional gravity and flotation flowsheet, with gold recoveries up to 96.9% and copper rougher recoveries above 97%. The Camp Creek system includes the Glenfiddich, Northside, and Talisker vein systems and the Oban diatreme breccia, with the porphyry beginning at approximately 300 m depth and intersected by drilling to depths of more than 1,500 m. Selected previously reported drill intercepts include 95.00 m of 1.70 g/t Au and 628.00 g/t Ag from 6.00 m depth in THN11-60 (Oban Breccia), including 9.25 m of 3.04 g/t Au and 2,984.00 g/t Ag; 554.70 m of 0.57 g/t Au, 43.18 g/t Ag, and 0.24% Cu from 97.00 m depth in THN19-150 (Oban Breccia); 16.00 m of 3.40 g/t Au, 96.08 g/t Ag, and 0.59% Cu in THN25-322 (Glenfiddich); 14.75 m of 1.71 g/t Au, 149.00 g/t Ag, and 1.25% Cu in THN26-372 (Glenfiddich), including 1.50 m of 11.30 g/t Au, 971.00 g/t Ag, and 8.33% Cu; and 28.35 m of 1.63 g/t Au, 76.79 g/t Ag, and 0.61% Cu in THN25-325 (Northside). Deep drilling since 2020 has returned intervals such as 976.52 m of 0.22% Cu, 0.07 g/t Au, 2.06 g/t Ag, and 154 ppm Mo in THN21-183; 967.71 m of 0.25% Cu, 0.09 g/t Au, 2.39 g/t Ag, and 186 ppm Mo in THN22-201, including 150.00 m of 0.60% Cu, 0.19 g/t Au, 5.13 g/t Ag, and 391 ppm Mo; and 647.83 m of 0.26% Cu, 0.11 g/t Au, 2.70 g/t Ag, and 274 ppm Mo in THN24-307, including 50.00 m of 0.54% Cu, 0.58 g/t Au, 5.33 g/t Ag, and 176 ppm Mo. Several holes ended in mineralization, and the porphyry remains open in multiple directions. Metallurgical composites were prepared from drill core sampled under Brixton's protocols, with core samples mostly taken at 1.50 m intervals and high-grade intervals at 0.50 to 1.50 m intervals. Blank, duplicate, and certified reference materials were inserted at a combined rate of up to 15%. Samples were analyzed at ALS Laboratory Facilities in North Vancouver, British Columbia, for gold by fire assay and for Ag, Pb, Cu, Zn, and 48 additional elements by four-acid digestion with ICP-MS finish. Brixton received initial scoping-level metallurgical test results from SGS Canada Inc., an independent laboratory, with each composite ground to a target primary grind size of 80% passing 75 µm (P80) and processed through a Knelson concentrator and Mozley table, followed by rougher flotation. The Porphyry X composite assayed 0.22 g/t Au, <10 g/t Ag, 0.52% Cu, 519 ppm Mo, and 3.37% S. The Oban Breccia composite assayed 3.77 g/t Au, 1,280 g/t Ag, 0.93% Cu, 5.73% Pb, 2.80% Zn, 0.44% Sb, and 12.0% S. The high-sulphidation veins composite assayed 3.44 g/t Au, 148 g/t Ag, 0.77% Cu, and 17.2% S. Gold head grades calculated from metallurgical balances were higher than direct head assays for all three composites (0.40, 4.45, and 4.53 g/t Au, respectively). The Oban Breccia rougher concentrate carried 40.2% of the feed mass, and the high-sulphidation veins rougher concentrate carried 46.9% of the feed mass.
