Pilot Mountain - Significant Drilling Results

Desert Scheelite: Further High-Grade Tungsten, Copper, Silver & Zinc

Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), 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 final batch of drillholes at the Desert Scheelite zone covering PM25-41 to PM25-052 (Figure 1, Table 1) with results confirming further significant high-grade tungsten mineralisation over significant widths (Table 2).

To date, a total of 82 drillholes have completed, with 61 drillholes at Desert Scheelite, including 49 resource holes, 7 geotechnical holes and 5 metallurgical holes. At the Garnet Zone all 20 planned resource drillholes have previously been completed and at Porphyry South a single drillhole has been completed to date.

Oliver Friesen, CEO of Guardian Metal, commented:

"We are very pleased to now have all of the results in hand from the Desert Scheelite resource drilling, marking another important step toward our goal of delivering Mined in America tungsten to the United States market. Once again, this latest batch of assays has confirmed zones of high-grade tungsten, copper, silver and zinc, with numerous holes returning significant widths of tungsten mineralisation.

"We now eagerly await initial results from our inaugural Garnet Zone drilling and look forward to commencing drilling at Tempiute in the coming weeks. With multiple rigs soon to be mobilised across our Nevada based co-flagship tungsten projects, Guardian Metal is entering one of its most active and potentially value-accretive periods in the Company's history, with significant news flow expected over the coming months."

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 a mineralised 21.6 m interval in PM25-043, a 33.9 m interval in PM25-045, a 45.7 m interval in PM25-047 and a 24.4 m interval in PM25-051 as well as multiple others throughout the holes reported herein. It is worth noting that the intersections in holes PM25-042, PM25-043 and PM25-045 could be significantly wider accounting for four sample intervals with no core recovery.

§ High-grade individual assay results up to 1.09% W0₃, 9.98% zinc (Zn), 337ppm silver (Ag), and 1.3% copper (Cu) with select highlight interval of 8.23m of 1.23 % WO₃Eq or 4.26 % CuEq from PM25-045 nested within a broader 33.9m continuously mineralised interval from that drillhole.

§ Initial Garnet Zone drilling analytical results are expected imminently with inaugural results released to the market in the coming weeks.

§ Several samples from the Company's newly staked 'Pilot North Project' are now in the laboratory with results expected in the coming weeks.

^* Metal Equivalents: Copper Equivalent ("CuEq") and W0₃ Equivalent ("WO₃Eq") are calculated using a tungsten price of US $485/MTU, a zinc price of US$1.241/lb, a copper price of US$4.34/lb and a silver price of US$37.39/Oz (see Table 3).

** Includes up to 1.37m core loss around 115.67m downhole.

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.

Table 2 notes: Summary of certificated assay results provided by accredited laboratory ALS USA Inc

Analytical methods utilised: ME-ICP61 for all samples, with ME-ICP61 overlimit samples also analysed using Ore Grade packages Ag-OG62, Cu-OG62, Pb-OG62, Zn-OG62, and W-XRF15c for high-grade tungsten.

ppm: parts per million, 10,000 ppm = 1%

a: ALS method ME-ICP61;

b: WO₃ % from method ME-XRF15c

c: ALS method Zn-OG62

?: denotes WO₃ % calculated using W ppm (ME-ICP61) calculated as W % multiplied by 1.2611

F: denotes Zn % from overlimit methodZn-OG62

ß denotes Cu % from overlimit method Cu-OG62

? denotes Ag g/t from overlimit method Ag-OG62
