PETROGRAPHIC ANALYSES AND GEOPHYSICS SUPPORT
PORPHYRY COPPER-GOLD DEPOSIT POTENTIAL ON
PJX RESOURCES’ DEWDNEY TRAIL PROPERTY
Toronto, Ontario – May 10, 2023 – PJX Resources Inc. (“PJX”) is pleased to announce that results from Vancouver
Petrographics’ (“VanPetro”) thin section and polished section analyses of rock samples from the Estella Basin support
porphyry copper-gold deposit type potential on the Dewdney Trail Property. Deposit potential is also supported by
large (5 km diameter) ring features in airborne magnetic data that may define the margins of collapsed plutons at
depth. Porphyry copper-gold deposits often occur above and along pluton margins.
Porphyritic intrusions (alkalic porphyries, felsitic rhyolite, trachylatite), breccias, meta-sediments, carbonates, plus
quartz-filled veins comprise the various Estella Basin samples that were analyzed by VanPetro laboratory . Typical
porphyry deposit alteration assemblages (Ca -Mg-Fe-carbonates, pyrite, epidote, seri cite, chlorite) as well as
disseminated and vein copper minerals were identified and are similar to those that characterize alkalic porphyry
copper-gold deposits.
The Estella Basin target area, with gold-copper-silver mineralization related to alkalic intrusions, is one of a number of
target areas on PJX Resources 116 km² Dewdney Trail Property in the Sullivan Mining District.
John Keating, President of PJX commented: “It has taken 10 years to consolidate the mineral rights to the Dewdney
Trail Property and the historical Estella mine. Geological and geophysical data combined with copper and gold
mineralization in soils and porphyry intrusions at surface all support the potential to discover porphyry type deposits
on the Dewdney Trail Property. There are multiple drill ready targets that we plan to test for the first time this year.”
Factors supporting porphyry deposit potential include:
• Differentiated intrusions with porphyritic r ock types ranging from syenite to granodiorite in composition.
• Hydrothermal breccias.
• Copper sulphide and pyr ite mineralization in veins and disseminated in the fine-grained groundmass of
various porphyry phases (see photo A).
• Clustering of multiple and varied intrusions.
• An exposure level that indicates only the top of some intrusions are exposed. This supports the potential for
additional mineralization at depth.
• Airborne geophysical Magnetic and EM signatures of the intrusions that are similar to known p orphyry
copper-gold deposits elsewhere in the world. Th ese include large ring features (5 km across) that may
represent the margins of multiple plutonic phases (magmatic centers) at depth that could generate porphyry
and intrusion related deposits (see figures 1 and 2).
• Large co incident soil geochemical anomalies of gold, co pper, arsenic, molybdenum and other metallic
elements associated with mineralized intrusions and geophysical targets (see figures 3 to 6).

VanPetro’s assessment indicates that this is a micro-fractured porphyritic quartz-bearing syenite dominated by fine
to very coarse, subhedral to euhedral K -feldspar phenocrysts (in places, replaced by calcite), intergrown with
accessory plagioclase phenocrys ts and quartz, floati ng w ithin a groundmass that is dominated by K -feldspar,
intergrown with plagioclase, quartz, muscovite flakes, plus minor apatite and scattered calcite spar. Pyrite,
chalcopyrite (copper sulphide) blebs and hematite are scattered in th e groundmass. Discont inuous veinlets,
crosscutting phenocrysts and groundmass are filled with calcite and quartz. A separate grab sample of this phase of
porphyry with quartz veins analyzed 6.9 g/t gold, 447 g/t silver, 1.1% copper.

• Estella Basin’s First target to test is the syenite/alkalic intrusion associated with gold, copper and silver
mineralization discovered last year. Intrusion appears as a magnetic high (red colour).
• Additional targets are the Donut shaped magnetic anomaly and a syenite/alkalic porphyry with limited
access at the base of a cliff . Porphyry copper-gold deposits are known to have a magnetic high and/or a
donut shaped magnetic signature.
• Two large ring features in the magnetic data (approximately 5 km across) outline what may be the outer
margins of multiple collapsed plutons at depth that could generate porphyry copper-gold type deposits.
• The possible plutons (magmatic centres) are aligned along a major north trending overturned anticline fold
axis that would provide loci for plutons.
• Note how the syenite/alkalic porphyry intrusions and donut shaped magnetic anomaly occur along the ring
features. Porphyry copper-gold deposits are known to occur along the margin of plutons.

• Mapping suggests that t he more conductive areas (pink to red colour s) are related to sedimentary rocks
containing iron sulphide, carbonaceous material, and possible massive sulphide mineralization.
• The more conductive areas appear to disappear in the centr e where a large area of lower conductivit y
(diffuse red) may represent a pluton at depth.
• The lower conductivity area may have been created when the pluton absorbed the conductive iron sulfides
and carbonaceous material that are often required to form copper-gold porphyry type deposits.
• The ring feature, about 5 km across, represents the outer margin of the possible pluton.
• Alkalic/syenite porphyry in trusions and the donut shaped magnetic anomaly occur along the ring feature.

Note how anomalous concentrations of gold, copper, arsenic and molybdenum occur in proximity t o porphyry
intrusions, and the large donut shaped magnetic anomaly that may represent a potential copper-gold porphyry type
deposit at depth.
