Brixton Metals Discovers Multiple Porphyry Systems at the North Target on its
Thorn Project
VANCOUVER, British Columbia, December 16, 2024 (GLOBE NEWSWIRE) - Brixton Metals
Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce
North Target drill hole results of the 2024 season from its wholly owned Thorn 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
• Brixton Metals’ maiden drill program at the North Target has intercepted a Mo-Cu porphyry
system with mineralization starting from surface consisting of:
o Multiple generations of porphyry-style quartz and quartz -anhydrite veins hosting
molybdenite, pyrite, and chalcopyrite accompanied by potassic alteration halos
o Anomalous copper and molybdenum within multi-kilometer scale alteration zones of
phyllic, potassic, and propylitic alteration centered around multi- phase crowded
porphyritic diorites
• A ground magnetotelluric geophysical survey has identified numerous conductive features
that correlate with zones of hydrothermal alteration
• Geochronology sampling highlights discovery potential of Thorn Project with multiple
metallogenic epochs identified
Vice President of Exploration, Christina Anstey, stated, “The results from the North Target highlight
the extraordinary discovery potential of the Thorn Project. Intersecting multiple porphyry systems in
an area that has seen minimal historical exploration is a testament to the strength of our technical
approach. These early findings not only confirm the presence of a robust mineralized syste m, but
also set the stage for further exploration to uncover higher-grade zones and additional targets across
this expansive and underexplored district.”

Technical Discussion
The North Target is located approximately 10km northwest of the Camp Creek Porphyry Target.
Prior to the 2024 field season, exploration at the North Target has been limited to small and sporadic
surficial sampling programs and has never been drilled. Through compilation of historic work and
geological mapping by Brixton Metals, multiple porphyry, epithermal, and skarn mineral occurrences
accompanied by large alteration footprints have been identified within a north -northwest trending
11km by 4km area, highlighting the potential for a large mineral system. The North Target is underlain
by Stuhini Group upper Triass ic mafic volcanics and Laberge Group lower Jurassic sedimentary
rocks. These units are intruded by multiple Late Cretaceous to Eocene intrusions.
The 2024 field season commenced with a SPARTAN Ma gnetotelluric (MT) geophysical survey
consisting of a 108 station grid with 1-kilometer spacing. This was followed up by 4 drill holes at the
Wild Moly and Main Gossan target areas for a total of 2,266m.
Wild Moly
Wild Moly has a surface expression of strong quartz -sericite-pyrite alteration with quartz -
molybdenite-chalcopyrite veins and a coincident low resistivity feature identified from the MT survey.
This target was tested with two drill holes for a total of 1,071m leading to the discovery of a previously
unrecognized Mo- Cu porphyry system . While copper grades average 0.04% in THN24- 312 and
0.06% in THN24-313, narrow intervals have returned >0.1% Cu and further work will evaluate the
potential for zones of higher-grade copper. With an at least 1.8km by 1.2km area of phyllic alteration
mapped at surface, the system remains open in all directions.
THN24-312 was drilled at an azimuth of 128.2 degrees, a dip -65.0 degrees, and to a depth of 650m,
targeting the highest density of mapped quartz veins and center of the low resistivity anomaly. The
drill hole collared into a crowded biotite-quartz-feldspar diorite porphyry from surface to 602.85 m
where Stuhini mafic volcanic tuffs and breccias were intersected until end of hole. Mineralization
occurs in quartz-anhydrite veins with pyrite-molybdenite and rare chalcopyrite. Potassium feldspar
and biotite alteration forms halos to veins with a pervas ive sericite -pyrite overprint. THN24-312
returned 638.00m of 0.023% Mo, 0.04% Cu from 12.00m, including 55.00m of 0.047% Mo, 0.05%
Cu from 595.00m.

THN24-313 was drilled from the same pad and collared at an azimuth 308.1 degrees, a dip of -65.1
degrees, and to a depth of 421m, testing a copper-in-soil anomaly. The hole collared into the diorite
porphyry until 116.35m where the lithology became Stuhini mafic volcanic dominant with sub -50m
intervals of porphyry. As with THN24 -312, porphyry-style mineralized quartz veins with potassic
halos were intersected throughout until alteration became chlorite-epidote-magnetite-pyrite
dominant at depth where i t is interpreted that the hole transitioned to the margins of the porphyry
system. THN24-313 returned 409.00m of 0.013% Mo, 0.06% Cu from 12.00m, including 19.00m of
0.12% Cu, 0.011% Mo from 275 .00m. The best copper values occur with in mafic volcanics at the
contact with the diorite porphyry.

Main Gossan
The Main Gossan consists of a 2.5km by 3.2km altered area with p ropylitic, sericitic, and locally
potassic alteration assemblages, widespread pyrite, and isolated occurrences of chalcopyrite,
copper oxides, and molybdenite at surface. It is underlain by Laberge Group sedimentary rocks
which are cut by multiple intrusive phases. The Main Gossan was tested with two holes totaling
1,195m targeting areas where porphyry -style quartz veins were observed on surface with a
coincident northeast trending conductive feature. The 2024 drilling has confirmed the presence of a
porphyry system at the Main Gossan.
THN24-296 was collared at an azimuth of 159.5 degrees, a dip of -68.8 degrees, and to a depth of
530m and THN24-298 was collared from the same pad at an azimuth of 245.1 degrees, dip of -60
degrees, and to a depth of 665m . Both holes collared into Laberge mudstone to conglomerate
horizons which are intruded by a hornblende- biotite-quartz-feldspar diorite porphyry. Chlorite-
epidote-magnetite-pyrite was the dominant alteration assemblage with structurally controlled zones
of sericite-pyrite overprint. Mineralization consisted of disseminated pyrite, commonly >5%, with rare
quartz-molybdenite and quartz -sphalerite-galena-chalcopyrite veins. Both holes ended in an
intrusive breccia with elevated copper values, including THN24-296 which returned 39.00m of 0.04%
Cu and 0.005% Mo from 492.50 meters to end of hole. While the Main Gossan holes returned no
significant intercepts, the widespread propylitic alteration suggests drilling intersected the margins of
a concealed porphyry system.

Geophysics
The MT survey has identified numerous near-surface conductive features across the target area.
With the survey successfully highlighting the Wild Moly porphyry discovery as a resistivity low, further
ground-truthing of other anomalies is planned for the 2025 field season . One resistive feature of
interest is a 3km wide donut-shaped conductor located at the south end of the target area (Figure
3). The flanks of the conductor correspond with quartz -sericite-pyrite alteration and the central
portion is interpreted to be covered by post -mineral volcanics. The geophysical data will be further
evaluated and will incorporate petrophysical properties collected on drill core and surface samples
into a constrained inversion.
Geochronology
A Re-Os geochronology sample from a molybdenite vein at the Main Gossan has returned an age
date of 58 +/- 0.2 Ma. While mineralization at the Main Gossan and Wild Moly are interpreted to be
Paleocene in age, 3km south of the Main Gossan, U-Pb zircon age dating of a porphyritic intrusion
with weak chalcopyrite mineralization has returned 85.5 +/- 0.7 Ma, coeval with the mineralizing PX
porphyry at the Camp Creek Porphyry Target. Along with known Late Triassic mineralization in the
central portions of the property and Neogene epithermal mineralization adjacent to the Thorn Project
at Newmont’s Hearts Peak Property, these results highlight the discovery potential of the area with
multiple metallogenic epochs identified.
