Empire Metals upgrades to OTCQX, enhancing accessibility for U.S. investors

Empire Metals Limited (LON:EEE; OTCQX:EPMLF), the resource exploration and development company, is pleased to announce that it has advanced to trade on the OTCQX® Best Market ("OTCQX"). The Company has upgraded to OTCQX from the OTCQB® Venture Market and will begin trading today on OTCQX under the symbol "EPMLF". U.S. investors can find current financial disclosure and Real-Time Level 2 quotes for the Company on www.otcmarkets.com. U.S. investors can find current financial disclosure and Real-Time Level 2 quotes for the Company on www.otcmarkets.com.

Empire Metals continues to gain momentum through ongoing achievements in drilling results, metallurgical advancements, and product development at the Pitfield Titanium Project. These accomplishments have led to an upgrade for Empire on to OTCQX.

The cross-trading of Empire's ordinary shares on OTCQX is expected to enhance the visibility and accessibility of its shares to U.S. investors, who will also benefit from greater liquidity from a broader pool of potential investors globally. OTCQX is also the highest-level trading venue of the OTC Markets Group Inc. on which 12,000 U.S. and global securities trade.

By trading on OTCQX, Empire will engage directly with US investors, providing them with the same level of information and disclosure available to shareholders in the United Kingdom, but through US-facing platforms and portals. Additionally, the OTCQX cross-trading facility will enable US investors to access Empire's ordinary shares in US dollars, during US market hours.

Commenting on the announcement, Shaun Bunn, Managing Director, said:

"I am delighted to announce our upgrade to OTCQX. Building on the Company's international shareholder base, this further enhances the accessibility and visibility of our shares to both U.S. institutional and retail investors.

"Trading on OTCQX offers even more investors a pathway to participate in Empire's growth and gain exposure to titanium - a strategically important critical mineral with strong fundamentals. We look forward to welcoming new U.S. investors as shareholders."

About OTCQX

The ability to trade Empire's existing ordinary shares on AIM will remain unaffected by the OTCQX listing. The OTCQX Market is designed for established, investor-focused U.S. and international companies. To qualify for OTCQX, companies must meet high financial standards, follow best practice corporate governance, and demonstrate compliance with applicable securities laws. Graduating to the OTCQX Market from the OTCQB Market marks an important milestone for companies, enabling them to demonstrate their qualifications and build visibility among U.S. investors.

About Empire Metals Limited

Empire Metals is an AIM-listed and OTCQX-traded exploration and resource development company (LON: EEE, OTCQX: EPMLF) with a primary focus on developing Pitfield, an emerging giant titanium project in Western Australia.

The high-grade titanium discovery at Pitfield is of unprecedented scale, with airborne surveys identifying a massive, coincident gravity and magnetics anomaly extending over 40km by 8km by 5km deep. Drill results have indicated excellent continuity in grades and consistency of the in-situ mineralised beds and confirm that the sandstone beds hold the higher-grade titanium dioxide (TiO₂) values within the interbedded succession of sandstones, siltstones and conglomerates. The Company is focused on two key prospects (Cosgrove and Thomas), which have been identified as having thick, high-grade, near-surface, in-situ bedded TiO₂ mineralisation, each being over 7km in strike length.

An Exploration Target* for Pitfield was declared in 2024, covering the Thomas and Cosgrove mineral prospects, and was estimated to contain between 26.4 to 32.2 billion tonnes with a grade range of 4.5 to 5.5% TiO₂.  Included within the total Exploration Target* is a subset that covers the in-situ weathered sandstone zone, which extends from surface to an average vertical depth of 30m to 40m and is estimated to contain between 4.0 to 4.9 billion tonnes with a grade range of 4.8 to 5.9% TiO₂.

The Exploration Target* covers an area less than 20% of the overall mineral system at Pitfield which demonstrates the potential for significant further upside.

Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal or pigment quality product at Pitfield, to realise the full value potential of this exceptional deposit.

The Company also has two further exploration projects in Australia; the Eclipse Project and the Walton Project in Western Australia, in addition to three precious metals projects located in a historically high-grade gold producing region of Austria.

*The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. See RNS dated 12 June 2024 for full details.
