Pilot Mountain - Significant Drill Result

Desert Scheelite: First Drillhole PM24-001 Intersects Three Strongly Mineralised W-Zn-Ag-Cu Intervals

Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), a strategic development and mineral exploration company focused in Nevada, USA, is pleased to announce the first diamond core 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. 

Laboratory assay results from drill core samples confirm diamond core drillhole PM24-001 from the Desert Scheelite deposit has intersected three zones of highly significant tungsten mineralisation together with ancillary zinc, silver and copper (see Table 1 & Table 2).

Oliver Friesen, CEO of Guardian Metal, commented: 

"Guardian Metal could not have asked for a better start to the Pilot Mountain drilling programme with the significant assay results achieved in the first drill hole PM24-001. The results demonstrate three distinct strongly mineralised tungsten-silver-zinc-copper intervals with the deepest interval remaining open at depth.

"Drilling has been ongoing since May and we are currently partway through the 21^st hole, with drilling continuing at pace.

"The coming weeks and months will undoubtedly be the busiest period for Guardian Metal to date and we are looking forward to providing the market with commercial/technical updates, including further assay data and interpretation, as results continue to flow in from the laboratory.

"With Guardian Metal's investment in exploration and development and with the outstanding Project findings to date we consider Pilot Mountain to be a uniquely valuable strategic asset which we believe can contribute to various U.S. national security objectives, especially as, currently, there is no domestic production of tungsten, a much-needed critical defence metal."

 

HIGHLIGHTS:

 

§ Laboratory assay results confirm diamond drillhole PM24-001 at Desert Scheelite target (Figure 1) has intersected three strongly mineralised intervals totalling 38.7m of 'high-grade'¹ tungsten mineralisation.

 

§ PM24-001 high-grade downhole drill intersection composites comprise:

 

o 9m @ 0.37% W0₃ from 69.1m (with 2.48% Zn, 43.7g/t Ag, 433ppm Cu)

 

o 27.9m @ 0.42% W0₃ from 96.6m (with 1.30% Zn, 23.1g/t Ag, 1,245ppm Cu)

 

-     including 8m @ 0.84% W0₃ from 108.7m

 

o 1.8m @ 0.42% W0₃ from 150m to end of hole (with 1.44% Zn, 7.6g/t Ag, 217ppm Cu), interval remains open at depth and the Company is considering extending the hole.

 

§ Review of historical drilling records shows PM24-001 is one of the most strongly mineralised drillholes completed at Pilot Mountain/Desert Scheelite to date.

 

§ Individual standout very high-grade assay results include 1.37% W0₃ (108.7m - 110.2m downhole depth) and 1.44% W0₃ (114m - 115.5m downhole depth) which are some of the highest ever single drill assay results achieved across Pilot Mountain to date (see green interval in fig. 1).

 

§ Core sample assay results from ALS analytical method ME-ICP61 returned upper limit of detection ("overlimit") results for 20 tungsten samples (>3,000ppm W) and 15 zinc results (>10,000ppm Zn), three silver results (>100g/t Ag), and one lead result (>10,000ppm Pb). Overlimit samples were reanalysed utilising specific high-grade analytical packages².

 

§ The Company considers all three of the strongly mineralised zones within PM24-001 to be near surface, within the context of possible future mining options, further highlighting the importance of the Desert Scheelite tungsten deposit and the Pilot Mountain Project as a whole, and adding further impetus to its successful development pathway.

 

§ Based on various historical reports the Company has decided to selectively assay PM24-001 for gold (via fire assay) which is now underway.

 

§ Strong visual garnet mineralisation intersected throughout mineralised skarn-interval in PM24-001 (see fig. 1).

 

§ The Pilot Mountain diamond drilling programme commenced in May 2024 and to date 20 holes have been completed. The 21^st  drillhole is currently underway.

 

§ Drill core samples are submitted for laboratory assay in batches following detailed geological and geotechnical logging, results are subject to thorough quality control and quality assurance (QA/QC) verification and interpretation prior to release. The results for PM24-001 constitute the first batch of results. Subsequent batches will be released following completion of QA/QC verification and interpretation of results. Strong unreported visual results are pending including select scheelite (fig. 3) and chalcopyrite (fig. 4) dominate visuals which are available below.
