Among its latest highlights, hole LM18-16 intersected 7.87m at 2,787.26g/t silver and 0.27% cobalt, including 1m at 15,436g/t silver, 1.98% cobalt and 0.47% nickel.
Chairman and CEO Gary Thompson said the 1m interval was "spectacular" and equivalent to 12.67% cobalt, or 537 ounces per tonne of silver.
The results are the latest in a number of high-grade intercepts from Brixton's Cobalt Camp properties, where the company started drilling in January after closing a C$3 million (US$2.3 million) private placement.
It said the Langis mine had historically produced more than 10.4 million ounces of silver and 358,340 pounds of cobalt, and the Hudson Bay mine had produced 6.4Moz of silver and 185,570lb of cobalt.
The company had C$4.5 million in cash and no debt last month and counts Rob McEwen, Hecla Mining and Eric Sprott among its shareholders.
Brixton shares closed up 9.52% yesterday to C23c, capitalising it at $14.7 million.
