Guardian Metal Resources PLC Announces Pilot Mountain - Significant Drilling Results

Rhea-AI Summary

Guardian Metal Resources (GMTLF) has announced significant drilling results from its Pilot Mountain tungsten Project in Nevada. The company reported several high-grade tungsten and silver intersections from drillholes PM24-029 to PM24-039 at the Desert Scheelite zone.

Key highlights include:

• Drillhole PM24-034: 27.1m @ 0.46% W03, 32g/t Ag, with 5.3m @ 1.08% W03
• Drillhole PM24-038: Multiple intervals including 18.5m @ 0.28% W03 and 18.2m @ 0.25% W03
• Notable silver results up to 434g/t from PM24-034

The company is finalizing the last Desert Scheelite drillholes before moving to geotechnical drilling for the pre-feasibility study. Guardian has received a Notice Level permit for 20 drill pads at the Project's Garnet zone and is planning drilling at the newly discovered copper breccia zone within the Porphyry South target area.

Positive

• High-grade tungsten and silver intersections in multiple drill holes
• Received permit for 20 new drill pads at Garnet zone
• Discovery of new mineralized copper breccia zone
• Project advancing toward pre-feasibility study

Negative

• None.

Desert Scheelite: Further Very High-Grade Tungsten & Silver Results

LONDON, UNITED KINGDOM / ACCESS Newswire / March 3, 2025 / Guardian Metal Resources plc (LON:GMET)(OTCQX:GMTLF)('Guardian Metal' or the 'Company'), a strategic mineral exploration and development company focused in Nevada, USA, is 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 at the Desert Scheelite zone covering PM24-029 to PM24-039 (Table 1) with some further very high-grade tungsten and silver results being intersected (Table 2). To date, 51 drillholes have been completed.

The final planned drillholes into Desert Scheelite will be completed in the following weeks following which attention will be turned to geotechnical drilling to support the planned pre-feasibility study. The Company is also finalising the first ever geological model for the Gunmetal zone with drillholes to planned thereafter. Guardian has also received a Notice Level permit which allows for the excavation of 20 drill pads at the Project's 'Garnet' tungsten-copper-silver-zinc zone. Finally, preliminary drill planning is underway to target the newly discovered mineralised copper breccia zone within the Porphyry South target area located immediately south of Desert Scheelite.

Oliver Friesen, CEO of Guardian Metal, commented:

"As the need for a domestic U.S. mined source of tungsten continues to accelerate, we are pleased to able to produce another positive set of drilling results from the ongoing Pilot Mountain drilling campaign.

"Our Nevada based operating team is working hard to complete the final few Desert Scheelite drillholes, following the completion of which, they will commence work on the geotechnical drillholes to support the Project's pre-feasibility study. Work is also being progressed at the Project's Garnet and Gunmetal zones which host polymetallic tungsten-silver-copper-zinc mineralisation very similar to what is found at Desert Scheelite. We consider these as being low-hanging fruit targets given the historical widely-spaced drilling which uncovered significant intervals of skarn-style polymetallic mineralisation.

"We are also pleased to report that initial preparations are now underway for the Company's first ever boots on the ground work programme at Tempiute and we anticipate providing an update to the market covering more details in short order.

"As work progresses across our Nevada-based tungsten portfolio, the push to secure domestic supplies of critical and defence-related metals only strengthens the strategic positioning of Guardian Metal Resources within the U.S. and abroad."

Desert Scheelite Highlights:

• Of significance within this particular batch of results is the mineralised widths (>0.10% WO₃) encountered throughout several holes as well as the intersection of multiple broad mineralised intervals. These include mineralised 14.2m and 7.8m intervals in PM24-029, 19.4m and 27m intervals in PM24-031, 18.5m and 18.2m intervals in PM24-038 as well as multiple others throughout the holes reported herein

• Some of the most significant individual silver results from the 2024/2025 drilling programme were received from this batch of results including 434g/t (PM24-034), 345g/t (PM24-038), and two 355g/t Ag results from PM24-038.
