Significant Porphyry South Copper Results

Cu-Mo Mineralised Hydrothermal Breccia Zone Discovered

Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), a strategic development
and mineral exploration company focused in Nevada, USA, is pleased to announce
rock sample assay results confirming a copper-molybdenum (Cu-Mo) mineralised
hydrothermal breccia nested within the Company's Porphyry South target at its
100% owned Pilot Mountain Project ("Pilot Mountain" or the "Project)
located within the prolific Walker Lane Mineral Belt in Nevada, USA. Pilot
Mountain is the Company's flagship tungsten asset where drilling on the
deposit continues with a plan to continue to pre-feasibility engineering study
in 2025. Tungsten skarn deposits globally can be associated with source
intrusive rocks and "porphyry" bulk mineralisation. Exploration for both
deposit types has been part of the Company's broader geological model and
exploration programme.

On 11 November 2024 results were released from a widely spaced sampling
programme which returned elevated copper results from the Porphyry South
target*. The results supported the possibility of a copper-rich shell existing
within this target and the Company immediately commenced a more comprehensive
sampling programme, the results of which are presented herein.

Highlights:

 

§  Significant copper (Cu) and molybdenum (Mo) mineralisation identified
within an outcropping mineralised hydrothermal breccia zone at the Porphyry
South Target.

 

§   The hydrothermal breccia zone has returned the first at-surface
high-grade copper results from this burgeoning porphyry target, further
supporting the potential for a higher-grade copper mineralised shell within
the molybdenum-rich mineralised porphyry system identified by drillhole
PM24-002(1).

 

§   Highlight rock chip samples from various breccia outcrops include:
1.93% Cu, 204 ppm Mo and 0.94% Cu, 287 ppm Mo.

 

§   The Porphyry South target, one of 3 porphyry targets identified to date
at Pilot Mountain, has a current surface expression of 1,250m x 1,500m. This
represents a substantial target for further exploration, along with the nested
380m long, east-west striking mineralised breccia zone, which warrants
immediate follow up.

 

§ The surface copper mineralisation complements the highly anomalous downhole
molybdenum enrichment noted in diamond drillhole PM24-002, which is the only
drillhole at the Porphyry South target.

 

Oliver Friesen, CEO of Guardian Metal, commented:

"We are very pleased with the confirmation of high-grade copper and molybdenum
mineralisation at surface from a newly discovered mineralised breccia found
within the Porphyry South target. These results validate our belief in the
significant potential of Pilot Mountain as a large-scale multi-metal project.
The discovery of a hydrothermal breccia zone with outcropping Cu-Mo
mineralisation is a game-changer for this underexplored target area and
underscores the potential scale and quality of this asset."

 

Further Information

 

Previous rock chip sampling across the Porphyry South target identified
elevated Cu and Mo concentrations across the expansive zone of
quartz-sericite-pyrite ("QSP") hydrothermal alteration. Subsequent geological
fieldwork across this area has identified an outcropping, highly oxidised,
magmatic-hydrothermal breccia which can be traced for several hundred metres
and other gossanous outcrops (Figure 1 & 2). Copper surface showings
across the area include chrysocolla, malachite and chalcocite associated with
oxidised sulphide bearing quartz veins. Magmatic-hydrothermal breccias are
thought to form during the porphyry intrusion, they can often contain
high-grade mineralisation because of their intrinsic permeability (Figure
3).(2)

 

The rock chip sample assay results from multiple outcrops of hydrothermal
breccia and gossans (indicating oxidised sulphides) at Porphyry South are
presented in Table 1 and Figure 4. These results illustrate the presence of a
copper mineralised shell within the molybdenum mineralised porphyry system
discovered by PM24-02, and further support the Company's belief that a large
but almost entirely untested sub cropping Cu-Mo porphyry system exists within
the Project.
