Pilot Mountain - Garnet Update

Guardian Metal Resources plc (LON:GMET, OTCQX:GMTLF), a mineral exploration company focused on tungsten, copper, silver, gold and lithium within Nevada, USA, is pleased to announce an update regarding its 100% owned flagship Pilot Mountain Project ("Pilot Mountain" or the "Project") located within the Walker Lake Mineral Belt in Nevada, USA.

On 8 February 2024, the Company highlighted the significant garnet potential that exists at Pilot Mountain. This announcement may be viewed through the link below:

Highlights:

§ As part of multiple project development steps that are currently progressing in parallel, garnet bulk sampling will be commissioned imminently with a circa 300kg composite sample to be shipped to a highly respected laboratory for detailed metallurgical testing within the next few days. The bulk sample consists of approximately 118m of half-core samples taken from six different historical drillholes.

§ Industrial garnet is demonstrated to comprise an average of 40% of many mineralised intervals across the known deposit areas (Desert Scheelite & Garnet). Considering the size of the mineral resource at present, the Company is of the belief that the industrial garnet component, subject to completion of the metallurgical study, could be material to overall Project economics.1,2

§ The results will be incorporated into the pre-feasibility study ("PFS") work that is currently being progressed by the Company in association with its engaged engineers and environmental specialists. A detailed report is expected to be in hand from the engaged engineers shortly and next important steps required for the planned PFS will commence shortly thereafter.

§ The Company has made significant drilling progress since its last update on 25 June 2024 and a further drilling update is expected to be released to the market shortly. Geophysics results from the Company's largest ever geophysical campaign are expected imminently and will be released to the market as soon as possible.

Oliver Friesen, CEO of Guardian Metal, commented:

"We are now in the midst of what is without a doubt the busiest period in the Company's history. There are several exploration and development workstreams that are all in progress and moving forward together.

"Since the garnet potential was first investigated by the Company, and determined to be potentially significant, it has been high on our list to get the next steps in motion. The exploration crews who are doing a fantastic job in the field, alongside their daily duties associated with ongoing drilling, were able to prepare the bulk sample that will be shipped shortly for metallurgical testing. This work is being supervised by our retained metallurgical specialist and we are very pleased to have him work alongside us to oversee this important study.

"These results will form the basis of important next steps which include determining the recoverability of the various garnet species, how they fit into the current flow sheet and following that their effect on overall project economics.

"With lots of workstreams moving forward at present, I am very much looking forward to releasing further updates to the market in short order."

The Pilot Mountain project is an advanced exploration and mineral resource definition stage project located in Mineral County in western Nevada. The project covers an area of 14.80 km2 (3,904.1 acres) and is located 200km southeast of Reno and 18km east of Mina, Nevada. It is well situated for the supply of power, water and skilled labour and proximity to transport infrastructure in Mineral County and is centred around four existing mineral deposits: Garnet; Good Hope; Gunmetal and Desert Scheelite, all of which possess significant skarn-style tungsten-copper-silver-zinc mineralisation. The Pilot Mountain project consists of 176 active lode mining claims and 4 filed mill site claims. The four mill site claims filed at the former Dunham mill site have secure access to groundwater supply sufficient for the proposed project.

Garfield Project

The Garfield Project is an exciting copper-gold-silver prospect consisting of 65 lode mining claims covering 9.18 km2 (2,268 acres) located in Mineral County, Nevada, approximately 14km due east of the town of Hawthorne and 120km due west-northwest of Tonopah. Exploration to date has included detailed geochemical sampling and follow up analysis which highlighted the presence of both porphyry and skarn-type mineralisation and alteration at the 'High-Grade Zone'. Further to this, mapping, prospecting and rock sampling was recently completed with results confirming presence of high-grade copper, silver and gold mineralisation as well as leading to the bedrock discovery of the Pamlico Au Zone with individual rock samples up to 18.35g/t Au, 1,225g/t Ag & 1.89% Cu. Following this, geochemical analysis of the full suite of data confirmed the strong presence of porphyry style mineralisation across the Project, as well as potentially overprinting epithermal style mineralisation leading to increased gold-silver prospectivity.
