Locksley Resources Limited ( ASX: LKY / OTCQX: LKYRF / ADR: LKYLY ) (“ Locksley ” or “ the Company ”) is pleased to announce the successful completion of a heavily oversubscribed capital raising ( “Placement”) , securing firm commitments to raise approximately A$17 million via a placement of new shares at A$0.24 per share to domestic and international professional and institutional investors.

The Placement was led by well established U.S. institutional investors, providing a strong endorsement of Locksley’s strategy to deliver a fully integrated U.S. based ‘Mine to Market’ critical minerals supply chain. Their participation brings not only capital but aligned sector expertise and ongoing engagement that supports the Company’s downstream development objectives within the United States.

The raise was conducted under the Company’s refreshed placement capacity pursuant to ASX Listing Rules 7.1 and 7.1A, following shareholder approval at the Annual General Meeting held on 28 November 2025.

Strategic Execution Enabled by the Placement

Proceeds from the Placement will accelerate execution across the following:

• Rapid Advancement of drilling, assay programs and structural mapping to define mineralisation across the Mojave Project

• Acceleration of downstream processing and American-made conversion planning for antimony products

• Enhanced positioning for engagement with federal level funding initiatives, supporting Locksley’s role within the U.S. critical minerals ecosystem

• Accelerated progression toward first-mover status in restoring domestic U.S antimony supply, aligned with national security and industrial demand

• Continuous parallel execution of permitting, stakeholder engagement, engineering and project scheduling

Locksley Managing Director, Kerrie Matthews, commented:

“The depth of support across both international and Australian institutional markets represents a strong validation of our strategic pathway. In particular, the strong level of U.S. participation aligns directly with our downstream ambitions and reinforces the commercial relevance of our development plan.

The involvement of leading U.S. institutional investors is more than capital allocation; it is a strategic endorsement of Locksley’s emerging role within the domestic U.S critical minerals sector. This support comes at a time when the U.S administration is emphasising critical minerals as a national security priority and seeking to reduce reliance on foreign-controlled processing capacity.

With this institutional backing, Locksley is positioned to advance its contribution to a U.S. based supply chain for antimony and rare earths.

Importantly, this funding allows us to execute at pace while continuing to progress federal engagement initiatives. The capital secures our ability to accelerate exploration, development planning, and downstream partnerships, unlocking the full potential of the Mojave Project.

We are delighted to welcome these new investors to the register and look forward to working with partners who can support our long-term growth agenda.”

MOJAVE PROJECT

Located in the Mojave Desert, California, the Mojave Project comprises over 491 claims across contiguous prospect areas, namely, the North Block/Northeast Block and the El Campo Prospect. The North Block directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials’ claims, highlighting the strong geological continuity and exploration potential of the project area.

In addition to rare earths, the Mojave Project hosts the historic “Desert Antimony Mine”, which last operated in 1937. Despite the United States currently having no domestic antimony production, demand for the metal remains high due to its essential role in defense systems, semiconductors, and metal alloys. With significant surface sample results, the Desert Mine prospect represents one of the highest-grade known antimony occurrences in the U.S.

Locksley’s North American position is further strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE & antimony production. With its maiden drilling program planned, the Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security.
