Pilot Mountain, Nevada - Significant Drill Results

Desert Scheelite: PM24-012 Intersects Outstanding Tungsten Mineralised Intersection

Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), a strategic development and mineral exploration 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 Project ("Pilot Mountain" or the "Project) located within the prolific Walker Lane Mineral Belt in Nevada, USA.

The laboratory assay results from the first diamond drillhole were covered in the Company's announcement on 18 September 2024 which may be viewed through the link below:

https://www.londonstockexchange.com/news-article/GMET/pilot-mountain-significant-drill-result/16670512

Laboratory assay results from drill core samples for the next twelve holes (PM24-002 to 013) have confirmed:

1.   An outstanding mineralised intersection in drill hole PM24-012 at Desert Scheelite which the Company believes will deliver a material upgrade to the resource model within this area.

2.   Confirmation of a molybdenum-rich mineralised porphyry system at the Porphyry South target area.

3.   The Desert Scheelite Parallel West Zone is tungsten rich.

4.   The balance of Desert Scheelite drillholes continue to increase confidence for updating the existing Mineral Resource estimate ("MRE").

The Pilot Mountain diamond drilling programme commenced in May 2024 and to date 24 holes have been completed for a total of 3,211 metres drilled. The 25^th drillhole is currently underway (Fig. 1).

Desert Scheelite Highlights:

§ Laboratory assay results (Table 2) confirm diamond drillhole PM24-012 at Desert Scheelite has intersected the best tungsten intercept ever recorded at Pilot Mountain including 39.3m of 'very high-grade' tungsten mineralisation.

§ The PM24-012 downhole drill intersection comprises:

o 39.3m @ 0.735% W0₃ (tungsten trioxide), 39.7g/t Silver (Ag), 0.44% copper (Cu) and 0.30% zinc (Zn) from 66 m.

-     including 19.8m @ 1.219% W0₃, 69.6g/t Ag, 0.75% Cu and 0.15% Znfrom 82.5 m.

§ Significantly, the vast majority of the PM24-012 high grade intercept is located within the open pit shell as envisaged in the previous scoping level mine design and presents the opportunity to upgrade the previous block model for this area in the planned MRE update (Fig. 2). The Company believes this result will lead to a material increase in the resource model within this area.

§ PM24-012 standout extremely high-grade individual assay results include 2.90% W0₃ (100.8m - 102.3 downhole depth which also includes 696g/t Ag) representing the highest ever single tungsten assay result achieved across Pilot Mountain within any recorded drill programme to date.

§ Following the receipt of these outstanding assay results, the Company has moved the drill rig back to the area of Desert Scheelite where PM24-012 was undertaken to test for extensions of this zone in multiple directions.

§ The Company's CEO has scheduled a site visit commencing the end of this week to review the PM24-012 core and to evaluate core as drilling progresses from this new zone. 

§ The balance of Desert Scheelite drillholes continue to increase confidence in the existing MRE. Resource upgrade and infill represents a very important step required to enable the completion of the Pre-Feasibility Study.

§ PM24-012 highlight interval above on a metal equivalent basis comprises 39.3m @ 3.45% CuEq (copper equivalent) and 1.02% WO₃Eq (tungsten equivalent).

The Copper Equivalent is calculated using a tungsten price of $330/MTU, a zinc price of US$1.4163/lb and a silver price of US$31.52/Oz. The W0₃ Equivalent ("WO₃Eq") is calculated using a copper price of US4.4115/lb, a zinc price of US$1.4163/lb and a silver price of US$31.52/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.

Porphyry South Highlights:

§ Assay results from the Company's first ever porphyry focussed drillhole at Pilot Mountain, PM24-002 (& PM24-002A) into the Porphyry South target, has confirmed the presence of what the Company believes is an arc-related porphyry molybdenum (Mo) system.

§ Arc-related porphyry molybdenum deposits are a substantial source for molybdenum metal and may have anomalous concentrations of tungsten. The deposits typically contain low-grade mineralisation (0.03-0.22 % Mo) as molyb-denite, but are large-tonnage, making them amenable to bulk mining open-pit techniques.¹

§ Mo results for PM24-002/A directly correlate with increased vein density and very highly anomalous Mo was intersected intermittently throughout the entire hole including:

From (m)	To (m)	Mo (ppm) #
25	28	347
37	40	236
90.5	93.6	266
188.7	191.1	529
215.2	218.5	268
223.8	225.7	1,170
270.4	273.4	413
321.4	324	507

350.6	353.6	235

# ALS method ME-ICP61

§ Given recent developments regarding, 1) the delineation of the Company's Porphyry West and North Targets²as well as, 2) the possibility that W-Ag-Zn-Cu skarn-related zones at the Project may be related to one large porphyry system³, the confirmation of an Arc-related mineralised Mo porphyry system at Porphyry South is considered significant.

§ With results in hand the Company is working with all available data to place this interval within the context of the overall mineralised porphyry system(s). Notice permit amendments are awaited which cover multiple drillholes into the various porphyry targets at Pilot Mountain.

§ Future drill holes are planned to investigate areas with greater quartz vein density, which is where the potassic core associated with the highest grades in most porphyry systems is likely to be found.

§ In addition to the tungsten, copper, silver, zinc and garnet potential (currently being investigated), the confirmation of a Mo-rich porphyry adds another metal of interest to the Project going forward.

§ Given the strong copper shows found at surface across the Project, as well as within the various skarn deposits,  it is believed that the porphyry may have the potential to host a copper-rich porphyry shell, and this hypothesis will be investigated further.

Desert Scheelite Parallel West (DSPW) Highlights:

§ Drillhole PM24-003, the first of two drillholes completed into the previously untested DSPW zone, returned 3.5m @ 0.235% WO₃. This confirms that the DPSW skarn-zone (with a large surface expressions of circa 600m by 100m) is tungsten rich, representing another important development for the Project.

§ The Company is conducting further investigations of any at surface mineralisation within this zone to help guide future drilling into this target. Further drill pad locations are also included in the drilling permit notice amendment that was most recently submitted to enable further drilling to be undertaken at DSPW.

Oliver Friesen, CEO of Guardian Metal, commented: 

"It is safe to say we are extremely excited about the results reported today, including PM24-012 which has delivered a globally significant tungsten result. Not only did we intersect 39.3m of 1.02% W0₃Eq**, but this extended interval is located almost entirely within the scoping level open pit mine design, in an area which was previously occupied by relatively low grade material from the previous resource model.

"The drillholes reported today confirm that further exploration and drilling is needed to fully assess the Project's potential, of which we believe we have just scratched the surface. With the US $2.75m strategic North American financing recently completed at 27p, we are very well funded and look forward to continuing to drive this extremely exciting Project forward at a time when the U.S. needs secure supplies of tungsten."
