at its Thorn Project
VANCOUVER, British Columbia, January 14, 2025 (GLOBE NEWSWIRE) - Brixton Metals
Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce
its regional prospecting-soil sampling program results and remaining drill results from its 2024
season at the wholly owned Thor n Project located in NW British Columbia, Canada. The Thorn
Project is an underexplored copper -gold porphyry district with many large-scale exploration target
areas identified.
Highlights
• Discovery of two new porphyry targets on trend along the Camp Creek corridor . The larger
of the two zones is called Catalyst which is located 6-8 km from the Camp Creek Porphyry.
Rock grab and chip samples of porphyry style stockwork veins from Catalyst returned up to
0.56% copper, 2.87 g/t gold, and 30.0 g/t silver. See Figures 1 to 5.
• Discovery of a porphyry style stockwork vein zones within a 3 km by 1.5 km altered area at
the Sentinel Target. Rock sampling from the main Sentinel area generated results of up to
1.54% copper, 0.54% molybdenum, 0.2 g/t gold and 21.7 g/t silver. See Figures 1, 6, and 7.
• Regional rock samples assaying up to 46.9 g/t gold and 35.3% copper (at Calibre), 1525 g/t
silver (at Misty).
Chairman and Chief Executive Officer, Gary R. Thompson, P.Geo., stated, “Our boots on the ground
exploration approach has generated three new and exciting copper-gold porphyry targets that have
never been drill tested. Brixton plans to drill some of these new targets in 2025 as well as follow up
drilling on the Trapper Gold Target and Camp Creek Copper-Gold Target.”

Technical Discussion
The 2024 exploration season at the Thorn Project included an extensive surficial sampling and
geological mapping program with a total of 1143 rocks, 316 soils and 28 stream sediment samples
collected. In addition to sampling, a TerraSpec mineral spectrometer was utilized scanning
approximately 2000 rock chips collected over the last two field seasons from across the project. The
resulting short-wave infrared (SWIR) spectra data is used to assist in vectoring towards concealed
porphyry deposits. Regional field work was focused on supporting 2024 drilling and advancing early-
stage exploration targets to generate drill targets for the 2025 field season. Sampling was conducted
across multiple target zones with highlights discussed below.

Copper Equivalent (CuEq) is calculated based on US$ 4.02/lb Cu, US$ 2105.6/oz Au, US$ 25.16/oz
Ag, $US 20.99/lb Mo. These prices represent the approximate metal prices and calculations assume
95% metal recoveries.

Catalyst-Tempest
At the end of the 2024 field season, two new Cu-Au-Mo porphyry targets were discovered adjacent
to the northeast striking Camp Creek fault that hosts the Camp Creek and Cirque porphyry targets.
With porphyry deposits often occurring in clusters or alignments , the new showings highlight the
prospectivity of this major structure. Both of the new targets are hosted in Late Cretaceous porphyritic
biotite-feldspar diorite intrusions with a U-Pb zircon geochronology sample returning an age date of
86.6 +/- 0.6 Ma. Overlying the porphyry are Windy Table volcanics with age dates of ~85- 82 Ma.
Field relationships between geological units suggest that mineralization at the new targets occurred
prior to the deposition of Windy Table volcanics and are therefore of similar timing to the Camp Creek
Porphyry.
The Catalyst showing, located 6 km northeast of the Camp Creek Porphyry Target, is defined by a
300 m long exposure consisting of stockwork quartz-chalcopyrite-molybdenite A veins hosted within
a strong quartz-sericite-pyrite alteration zone. The showing is located within a broader 1.6 km by 1
km northeast trending alteration zone hosting phyllic to argillic assemblages, which transitions into a
broader area of propylitic alteration. Soil sample assays suggest that Cu-Au-Ag-Mo mineralization
extends up slope from the sampled vein zone.
Rock samples from the Catalyst showing returned up to 0.56% Cu, 0.11% Mo, 2.87 g/t Au, and 30.0
g/t Ag, including a 1.55 m chip across a stockwork vein zone which assayed 0.46% Cu, 68 ppm Mo,
and 0.37 g/t Au (see Table 3). The anomalous gold values from samples containing porphyry style
veins are encouraging for the potential of a gold- rich porphyry system . A total of 93 soil samples
were collected with results up to 0.16% Cu, 0.24 g/t Au, 89 ppm Mo.

The Tempest showing is located 4.5 km east of the Camp Creek Porphyry and 2.5 km south of the
Catalyst showing, hosting a 500 m by 600 m zone of moderate to strong sericite-clay-pyrite altered
porphyry with high sericite crystallinity identified from the SWIR data. At the northwest end of the
target, a n area with limited outcrop exposure contains stockwork quartz-chalcopyrite-pyrite-
molybdenite A veins and pyrite-sericite D veins. The presence of copper sulphides , porphyry style
veins, and widespread sericite alteration indicates close proximity to a mineralizing intrusion. The
extents of alteration and mineralization are currently open to the west, north and east under cover of
glacial till and post-mineral volcanic deposits. A magnetic high to the north of the showing suggests
potential continuity of the hydrothermal system to the north. Rock sampling at Tempest returned up
to 0.36% Cu, 0.28 g/t Au, 10.8 g/t Ag, and 104 ppm Mo.

Sentinel Target
Sentinel is a newly recognized Cu- Mo porphyry target located within the East Target. The East
Target hosts several mineralized Late Cretaceous intrusions, including at the Bing and Icy Cu -Mo
porphyry targets. Sentinel is underlain by Late Triassic intrusive rocks and intermediate to felsic
volcanics of interpreted upper Cretaceous age. The target was first identified by a large clay anomaly
from Sentinel -2 remote sensing satellite data and follow -up talus fines sampling over the area
generated a large Mo-Cu anomaly.
In 2024 sampling and geological mapping was focused within the anomalous area leading to
discovery of multiple zones of stockwork porphyry style quartz veining accompanied by potassic,
phyllic, and argillic alteration assemblages that zone out to propylitic alteration, all within a 3 km by
1.5 km area. Vein density was systematically mapped, highlighting zones of greater than 10% quartz
veining and locally up to 30%. Sulphide abundance is low in the main vein zones, coinciding with low
copper values, and is interpreted to be the result of a leached cap. It is believed that sulphide
abundance should increase with depth below the leached cap. Rock sampling from the main Sentinel
area generated results of up to 1.54% Cu, 0.54% Mo, 0.2 g/t Au and 21.7 g/t Ag (see Table 4).
Extensive copper oxides were sampled 3.5 km to the southeast of the stockwork vein zone, hosted
in a potassium feldspar altered monzonite with samples assaying up to 1 .12% Cu. This area has
seen limited work and will be further investigated in 2025.

Calibre
The Calibre Target encompasses the region southwest of Brixton’s Camp Creek Cu- Au-Ag-Mo
porphyry and Trapper Gold Targets and hosts significant copper -silver-gold mineralization.
Numerous new showings were discovered in areas with no historic samples. Late Triassic to Eocene
intrusive and volcanic rocks host polymetallic veins with assays up to 46.9 g/t Au, 1040 g/t Ag, 35.3%
Cu (see Table 5). Of the 121 grab samples collected, 16 returned greater than 1% Cu. Of particular
interest are mineralized and altered intermediate to felsic volcanics of probable Late Cretaceous age,
not previously recognized in the area. This stratigraphically significant unit is associated with multiple
epithermal and porphyry mineral occurrences within the Thorn Project, including the Camp Creek,
Cirque, Catalyst-Tempest, and Sentinel Targets, and provides a favourable setting for magmatic -
hydrothermal alteration. The new showings will be further evaluated for porphyry and epithermal
potential in 2025.
