Brixton Metals (TSX-V:BBB) has achieved 97% gold recovery from initial metallurgical testing at the Trapper target within its flagship Thorn Project in British Columbia, Canada.
The scoping-level test work was conducted on a single ‘high-grade’ composite sample assaying 10.3 grams per tonne gold (Au) and 27.6g/t silver (Ag).
A separate screened metallic assay returned 13.9g/t Au, which Brixton says indicates the presence of coarse gold.
Gravity concentration recovered 12.3% of the gold into a concentrate representing just 0.08% of the feed mass, grading 1,486g/t Au.
Subsequent rougher flotation of the gravity tailings recovered a further 96.6% of the remaining gold into a rougher concentrate grading 33.9g/t Au and 91.8g/t Ag.
Together, the gravity and rougher flotation processes achieved a combined gold recovery of 97%.
“We are encouraged by the first metallurgical results from Trapper, where scoping-level test work returned 97% combined gravity and rougher flotation gold recovery,” Brixton Chairman and CEO Gary R Thompson says.
The results provide an initial indication of gold recoveries at Trapper as the company prepares a maiden mineral resource estimate (MRE).
Final drill assays support resource estimate
Alongside the metallurgical results, Brixton has reported assays from the final two drill holes expected to contribute to the maiden MRE.
Both holes intersected broad zones of near-surface gold mineralisation, including higher-grade intervals.
One hole returned 120m grading 0.67g/t Au and 3.91g/t Ag from 19.5m depth.
The second intersected 138m grading 0.80g/t Au and 2.34g/t Ag from 29m depth, including a 0.5m interval grading 37.10g/t Au and 13.90g/t Ag from 57m depth, where visible gold was identified.
Thompson says both holes were specifically positioned to support the maiden resource estimate, which the company expects to release in early 2027.
Broader exploration at Thorn
The Trapper target covers a gold-in-soil anomaly measuring approximately 4km by 1.5km, with visible gold previously identified in drill core and surface outcrops.
It forms part of Brixton’s larger 2,945km² Thorn property in northwest British Columbia.
Earlier this month, Brixton also reported the identification of a new ‘high-grade’ gold-copper-silver vein through ongoing exploration at Thorn.
Brixton Metals is a Canadian exploration company focused on advancing its five exploration projects.
