Rhea-AI Filing Summary

Guardian Metal Resources PLC (GMTL) reported new tungsten drilling results from the Tremor and Good Hope Zones at its 100%-owned Pilot Mountain project in Nevada. At the Tremor Zone (north), mineralization has been confirmed over about 200m of strike and 190m of dip, with key intercepts including 64.15m @ 0.20% WO3 (including 14.27m @ 0.34% WO3) in hole PM26-088 and 15.20m @ 0.28% WO3 in PMR26-078. At the near-surface Good Hope Zone, results included 12.95m @ 0.79% WO3 from 12.19m in GH26-01 and 13.11m @ 0.42% WO3 from 2.13m in GH26-02, together representing an apparent 23m thickness at an average 0.58% WO3. The Tremor discovery has prompted relocation of the planned tailings storage facility, which the company states is not expected to materially affect project costs or timeline. No mineral resource estimate has yet been prepared for Tremor or Good Hope; further drilling and evaluation are required.

Positive

  • Exploration at Pilot Mountain delivered high-grade tungsten intercepts at both the Tremor and Good Hope Zones, supporting potential expansion of mineralization beyond the current Pre-Feasibility Study resources.

Negative

  • None.

Filing Explained

The September 14 filing leaves the new zones at an early exploration stage: most Tremor assays remain pending, and neither Tremor nor Good Hope has a mineral resource estimate, so their contribution to Pilot Mountain is not yet quantified.

Defense Production Act investment US$6 Investment by U.S. Department of War in 2025 to support Pilot Mountain PFS
Pre-Feasibility Study financial
"beyond the mineral resources incorporated into the recently completed Pre-Feasibility Study"
A pre-feasibility study is an initial assessment that evaluates whether a proposed project or investment idea is worth exploring further. It involves examining basic factors like costs, potential benefits, and possible challenges, similar to conducting a preliminary check before deciding to invest more time and resources. This helps investors determine if pursuing the project further is practical and likely to be successful.
tungsten-skarn technical
"The Tremor Zone is a blind tungsten-skarn discovery that is obscured"
A tungsten‑skarn is a type of mineral deposit formed when hot, metal‑bearing fluids from an igneous intrusion react with nearby carbonate rocks, creating calc‑silicate (skarn) minerals that concentrate tungsten-bearing ores such as scheelite or wolframite. For investors, the term signals a specific geological setting that can host economically recoverable tungsten, affecting how companies estimate resource size, grade, mining methods and potential project value — similar to spotting a concentrated vein of metal in the rock.
Tailings Storage Facility technical
"adjacent to the tailings storage facility ("TSF") proposed in the recently completed PFS"
A tailings storage facility is a managed site—often a lined pond or engineered dam—where mining companies store the wet waste left after extracting minerals. Investors care because these sites carry long-term risks and costs (environmental damage, spills, regulatory fines, cleanup and closure liabilities) that can quickly reduce a mine’s value, halt production or trigger costly remediation, much like a leaking landfill can suddenly force unexpected expenses and legal trouble.
condemnation drilling technical
"Mineralization was identified during condemnation drilling completed within an area"
Condemnation drilling is the targeted boring of holes to test soil or rock on a specific parcel of land to see if it contains contamination, voids, or material that would make part of the site unusable or unsafe. Think of it like lifting a few floorboards to check for rot before deciding which rooms in a house can be rented out. Investors care because the results determine whether portions of a property must be set aside, cleaned up, or dropped from development plans, which directly affects costs, timelines and the value of a project.
Defense Production Act regulatory
"under Title III of the Defense Production Act of 1950, as amended, invested"
A U.S. law that lets the federal government prioritize, allocate, and financially support the production and supply of goods and services needed for national defense or major emergencies. For investors, it can quickly change a company’s sales outlook and production plans by directing contracts, speeding approvals, or providing subsidies—like a city mayor telling factories which products to make during a crisis—so affected companies may see rapid revenue or cost shifts.
Competent Person regulatory
"acts as the Competent Person under the AIM Rules - Note for Mining"
A competent person is a qualified, experienced professional who reviews, verifies and signs off on technical or regulatory information—such as reserve estimates, safety reports or clinical findings—so the public can trust the disclosure. Like a licensed inspector or trusted referee, this person brings documented skills and legal accountability to the statement, which matters to investors because their endorsement reduces uncertainty, helps assess risk, and supports fair valuation of a company’s claims.

 Tungsten Drilling Results Support Potential Resource Growth at Pilot Mountain
 
Guardian Metal Resources plc (NYSE.A: GMTL, LON: GMET, OTCQB: GMTLF), a strategic exploration and development company focused on tungsten in Nevada, USA, is pleased to announce positive tungsten drilling results from the newly discovered Tremor Zone and the previously untested Good Hope Zone both located on its 100%-owned Pilot Mountain tungsten project (“Pilot Mountain” or the “Project”) in Nevada. The drilling results provide further evidence of the potential to expand the mineralization identified at Pilot Mountain beyond the mineral resources incorporated into the recently completed Pre-Feasibility Study (“PFS”).
 
The Tremor Zone, a blind tungsten-skarn discovery announced on 4 June 2026, was identified by the Company's in-house technical team while drilling a target adjacent to the tailings storage facility ("TSF") proposed in the recently completed PFS. The drilling results achieved to date have prompted a  relocation of the planned TSF, which requires a revised design but is not expected to materially affect project costs or timeline.¹ Following the receipt of results from the discovery hole PMR26-077, follow-up drilling has been undertaken to test the Tremor Zone's extent along strike and at depth. In parallel, the Company has completed its first-ever drill holes at the Good Hope Zone, one of the Project's at-surface skarn targets that had, until now, remained untested by the Company.
 

Highlights
 
■
Extensive tungsten mineralization confirmed over 200m strike distance at the Tremor Zone (north), with mineralization remaining open in multiple directions, providing future potential to supplement the Pilot Mountain mineral resources. Drill results for the Tremor Zone (south) are pending.
 
■
Tremor Zone (north) significant downhole drill hole intersections included:
o
PM26-088: 64.15m @ 0.20% WO3 from 139.97m, including:
-         14.27m @ 0.34% WO3 from 147.68m;
 
o
PMR26-078: 15.20m @ 0.28%WO3 from 259.08m;
 
o
PM26-090: 5.11m @ 0.34% WO3 from 101.19m.
 
o
PM26-097 intersected several zones of tungsten mineralization, including
-         16.60m @ 0.19% WO3 from 53.23m downhole including 10.77m @ 0.23% WO3 from 59.06m;
-         44.08m @ 0.18% WO3 from 86.03m downhole including 6.17m @ 0.22% WO3 from 86.03m, and also including 10.84m @ 0.27% WO3 from 111.42m; and,
-         6.68m @ 0.23% WO3 from 144.72m.
 
■
Good Hope Zone drilling returned multiple tungsten drill intersections from near surface, located within 1.1 to 1.3km of the existing Pilot Mountain mineral resource areas. Good Hope downhole drill hole intersections included:
o
GH26-01: 12.95m @ 0.79% WO3 from 12.19m;
o
GH26-02: 13.11m @ 0.42% WO3 from 2.13m. GH26-01 and GH26-02 were twinned holes, with the latter being drilled to recover the upper part of the zone and together they represent a combined apparent thickness of 23 meters which carries an average grade of 0.58% WO3; and,
o
GH26-07: 13.32m @ 0.15% WO3 from 65.84m.
 
Notes: No Mineral Resource Estimate has been prepared for the Tremor Zone or the Good Hope Zone and further drilling and evaluation will be required to determine their significance to the broader Pilot Mountain Project. Significant mineralized intersections of 5m apparent width at or above the PFS Desert Scheelite and Garnet deposit Mineral Resource Estimate cut-off grade of 0.04% WO3 are summarized in Table 1 and Table 2. Drill collar locations are stated in Table 3 and shown in Figure 1.
 
 
Oliver Friesen, CEO of Guardian Metal, commented: 
 
"We have always maintained that Pilot Mountain has significant exploration upside, and these results reinforce the potential to expand tungsten mineralization beyond the mineral resources that underpin our recently completed Pre-Feasibility Study. The Tremor Zone did not form part of the PFS mineral resource, yet drilling continues to highlight meaningful size and scale, with mineralization remaining open in multiple directions. This has been sufficient for us to relocate the proposed TSF and preserve the option to incorporate the Tremor Zone into a future mine plan. At the Good Hope Zone, the first holes ever drilled have returned strong tungsten grades from surface, close to the existing resource areas.
 
"With numerous exploration targets still to be drill tested, we see potential to add further tungsten resources, subject to further drilling and evaluation, while the DFS, engineering and permitting advance in parallel and at pace as we work to make Pilot Mountain the first new tungsten mine on U.S. soil in over a decade."
 
 
Further Details
 
Tremor Zone
 
The Tremor Zone is a blind tungsten-skarn discovery that is obscured by alluvial cover with no direct surface outcrop. Mineralization was identified during condemnation drilling completed within an area that was under consideration as a location for the TSF. The initial discovery drillhole, PMR26-077 (reported on 4 June 2026), intersected five distinct zones of tungsten-rich skarn mineralisation.1
 
To date, 8,140 meters across 37 holes of combined core and reverse circulation (“RC”) drilling targeting the Tremor Zone and other condemnation targets has been completed, with the majority of Tremor Zone assays still pending. Mineralization has been confirmed in two separate areas, the northern and southern Tremor Zones, with drilling to date focused on the northern zone. Within the northern zone, mineralization has been confirmed over ~200m of strike extent and ~190m of dip extent and mineralization remains open in multiple directions. Results are still pending for the southern zone which has been intersected in one hole located 180m south of the northern zone and remains open for extension in multiple directions.
 
The Tremor Zone is located within a part of the Pilot Mountain Project that is royalty free. While the Tremor Zone was not incorporated into the PFS, the Company has retained flexibility within its infrastructure planning to allow for its potential inclusion in future studies, subject to further drilling and technical evaluation.
 
 
Good Hope Zone
 
The Good Hope Zone is one of the Project's at-surface tungsten skarn zones, which had been identified as offering resource growth potential. Mineralization is exposed in a window below younger Tertiary volcanics and is hosted in east-west striking, gently north-dipping beds of Luning Formation limestone adjacent to a large body of quartz monzonite intrusion, which is the causative intrusive phase across Pilot Mountain. The Good Hope Zone is located ~1.3km north of the Desert Scheelite resource area and ~1.1km east of the Garnet resource area. Mineralization at the Good Hope Zone has been defined over a strike length of ~100m starting from surface and down dip for ~65 meters. Mineralization is bound on the west by post-mineral faulting, which opens exploration and expansion potential seeking the offset portion of the zone.
 
The inaugural drill programme at the Good Hope Zone comprised 1,682m of combined core and RC drilling across 13 holes. Results confirm near surface high-grade mineralization and the potential to add new mineral resources in the future.
