Brixton Metals Drills 855.0m of 0.52% CuEq, including 109.87m of 0.86% CuEq all

within 1562.35m of 0.34% CuEq at Camp Creek Target on its Thorn Project

VANCOUVER, British Columbia, S eptember 21, 2023 (GLOBE NEWSWIRE) - Brixton Metals

Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce

the first 2023 drill results from its Camp Creek Copper Porphyry Target on its wholly owned Thorn

Project located in Northwest British Columbia, Canada.

Highlights

• Hole THN23-261 is the longest copper interval drilled at Camp Creek to date

o 1562.35m of 0.34% CuEq (0.19% Cu, 0.05 g/t Au, 2.81 g/t Ag, 180 ppm Mo)

o Including 855.00m of 0.52% CuEq (0.29% Cu, 0.06 g/t Au, 2.44 g/t Ag, 314 ppm

Mo)

o Including 109.87m of 0.86% CuEq (0.51% Cu, 0.08 g/t Au, 3.70 g/t Ag, 498 ppm

Mo)

o Significantly expanding the footprint of the Camp Creek porphyry mineralization

VP of Exploration, Christina Anstey, stated, “We are excited by the extent of the porphyry copper

mineralization at the Camp Creek Target and that this hole encountered 580 m of the main

mineralized porphyry. The copper mineralization remains open in several directions.”

Hole THN23-261 was drilled at an azimuth of 350.3 degrees, a dip of -79.4 degrees, with the collar

at an elevation of 780m and reached 1650m depth. This hole was designed to test the potential

extension of known porphyry mineralization encountered in holes THN21-184 (821.25m of 0.54%

CuEq including 318.25m of 1.03% CuEq) and hole THN22-221 (779.65 of 0.41% CuEq including

234.00m of 0.63% CuEq) that were drilled in 2021 and 2022 respectively. Hole THN23-261 is a

significant step-out and has successfully expanded mineralization by 468m towards the east from

hole THN21-184 and 245m to the southeast from hole THN22- 221 at a depth of - 400m elevation

below sea level (see Figure 2). Copper mineralization is largely hosted within the Cretaceous aged

Porphyry X unit and the Triassic Stuhini Group sediments of which both have been cut by several

unmineralized post-mineral dykes. Hole 261 intercepted the broadest intercept of Porphyry X to date

totaling 586.26m within a 756.07m interval. The hole ended at 1650m in P orphyry V , a newly

recognized non-mineral porphyry phase which also appears to cut the Porphyry X unit . Hole 261

yielded 1562.35m of 0.34% CuEq, including 855.00m of 0.52% CuEq, including 630.00m of 0.57%

CuEq, including 221.49m of 0.68% CuEq, and including 109.87m of 0.86% CuEq (see Table 1).

Table 1. Select Mineralized Intervals For Drill Hole THN23-261.

The true width of the mineralized intervals have not yet been determined.

Copper Equivalent (CuEq) is calculated based on US$ 3.82/lb Cu, US$ 1863.32/oz Au, US$ 22.59/oz

Ag, $US 23.19/lb Mo. These prices represent the approximate 1 year moving averages of metal

prices and calculations assume 95% recovery.

CuEq % = (Cu % + (0.711384* Au g/t) + (0.008624 * Ag g/t) + (0.000607 * Mo ppm)) * 0.95

Drill hole THN23 -258 was drilled at an azimuth of 111.69 degrees, a dip of - 78.62 degrees, an

elevation of 619m and was drilled to a total depth of 1130.00m. The objective of hole 258 was to test

for porphyry copper mineralization to the south of hole THN21- 183 and to test below the high-

sulphidation vein-breccia system encountered in previous near surface drill ing at the Glenfiddich

Zone. Hole 258 is located south-southeast from hole 183 at a pierce point of -400m elevation below

sea level. THN23-258 did not encounter the main mineralizing Porphyry X unit and the dominant

lithology was hornfels altered Stuhini Group sediments. Assay results returned 1109.40m of 0.20%

CuEq, including 330m 0.31% CuEq, and 32m of 0.54% CuEq (see Table 2 for details). Although no

Porphyry X was intercepted within hole 258, porphyry-style alteration was observed suggesting that

the hole was drilled along the edge of the system.

Drill hole THN23-259 was drilled at an azimuth of 187.36 degrees, a dip of -81.00 degrees, at collar

elevation of 757m and to a depth of 522.06m. The hole was designed to test for the eastern extension

of mineralization previously drilled in hole 184, however it was abandoned due to poor ground

conditions and did not reach its target depth. Hole 259 returned 2m of 0.63% CuEq, notable for its

elevated silver at 19.61g/t Ag. The targeted location at depth will be tested with a follow -up hole

during the 2023 season from a different pad location.

Drill Hole THN23 -260 was drilled at an azimuth of 357.10 degrees, a dip of -81.21 degrees, at a

collar elevation of 829m to a total depth of 1196. 62m. Hole 260 was designed to test for porphyry

copper mineralization below the near -surface, high-sulphidation veins at the Talisker Zone. Broad

intervals of prominent skarn-type alteration with sphalerite mineralization were encountered with only

narrow copper intervals suggesting that this far-north step-out location is more distal to the core

system. Hole 260 returned 753.50m of 0.12% CuEq, including 10.50m of 0.35% CuEq.
