Pilot Mountain - Significant Drill Results
Desert Scheelite: Further Very High-Grade Tungsten & Copper Results
Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), a strategic mineral exploration and development company focused in Nevada, USA, is very pleased to announce further drillhole assay results from the Company's ongoing drilling campaign at its 100% owned Pilot Mountain tungsten Project ("Pilot Mountain" or the "Project) located in Nevada, USA.
Laboratory assay results from drill core samples have been received from the next batch of drillholes covering PM24-014 to PM24-017 with some further very high-grade tungsten and copper results being intersected as well as one of the longest mineralised intervals ever drilled at Pilot Mountain from PM24-017. To date 37 drillholes have been completed, the 38th drillhole is currently underway (Fig. 1).
Oliver Friesen, CEO of Guardian Metal, commented:
"Tungsten, classified as a 'Dual-Use' metal, is indispensable in both modern industrial and military applications, making it critical for U.S. national and economic security. Given the current geopolitical climate and the United States' tungsten import reliance, the timing could not be better for Guardian Metal to be advancing its 100% owned Pilot Mountain tungsten Project located in mining friendly Nevada.
"With these latest high-grade tungsten and copper drill assay results now reported, we are one step closer to updating the Mineral Resource and mine plan for inclusion in our pre-feasibility study and to the Company's ultimate goal of supporting the United States' onshoring efforts for this very important Dual-Use metal."
Desert Scheelite Highlights:
§ Laboratory assay results confirm diamond drillhole PM24-017 at Desert Scheelite has intersected a 46m mineralised interval, one of the longest recorded to date at Pilot Mountain.
§ PM24-017 downhole highlight drill intersections comprise:
o 46m @ 0.413% W03, 12.2g/t Ag, 2,476ppm Cu & 0.37% Zn from 66.4 - 112.4m (46m @ 0.55% WO3Eq* or 2.04% CuEq**); including
- 10.8m @ 0.681% W03, 1.2g/t Ag, 684ppm Cu & 0.18% Zn from 66.4 - 77.2m (10.8m @ 0.72% WO3Eq* or 2.67% CuEq**); and
- 7.6m @ 0.917% W03, 29.2g/t Ag, 10,982ppm Cu (1.098%) & 0.64% Zn from 101.2 - 108.8m (7.6m @ 1.36% WO3Eq* or 5.04% CuEq**).
§ PM24-014 downhole highlight drill intersection comprises:
o 15.1m @ 0.141% W03, 45.2g/t Ag, 12,923ppm Cu (1.292%) & 0.65% Zn from 20.4 - 35.5m (15.1m @ 0.68% WO3Eq* or 2.54% CuEq**).
§ The vast majority of the intercepts above are located entirely within the planned pit shell and locally represent a significant upgrade from the low grade block model that occupied the area beforehand.
§ Individual standout extremely high-grade assay result of 1.5m @ 5.02% Cu (25m - 26.5m downhole depth) from PM24-014 represents the second highest drilled copper assay results achieved from Pilot Mountain to date.
*,**Copper and W03 Equivalent ("WO3Eq") are calculated using a tungsten price of $330/MTU, a zinc price of US$1.3407/lb, and copper price of US4.0334/lb and a silver price of US$31.31/Oz.
Cautionary note: The metal equivalent calculations do not consider any metallurgical factors and assume 100% recovery and 100% payability of all metals, as a result the stated equivalents are provided for illustrative purposes only.
Copper Porphyry Update PM24-004:
Company geologists have completed a further review of assays previously reported from PM24-004. Significantly, high-grade copper was intersected within a mineralised quartz monzonite (porphyry). Mineralisation includes disseminated chalcopyrite and molybdenite in the quartz monzonite as well as an approximately 0.4m wide chalcopyrite-pyrite-quartz vein. Assays across this interval returned 2.8m @ 1.00% Cu & 18.7 g/t Ag, including 0.4m @ 2.96% Cu & 47.3 g/t Ag.
On 11 November 2024 the Company announced the findings of a study which supported the likelihood that a copper rich zone may exist within the Porphyry South target.1 The presence of high-grade copper successfully intercepted within a porphyry interval from PM24-004 further increases the prospect of copper enrichment within Porphyry South as well as other porphyry targets across Pilot Mountain.

Chalcopyrite, pyrite and molybdenite are also disseminated in the quartz monzonite. Qtz = quartz, Cpy = chalcopyrite, Py = pyrite, QM = quartz monzonite.
