Locksley Resources Expands Regional Exploration Strategy after Adding 249 New Claims to Mojave Project

Locksley Resources (ASX: LKY) has increased its landholding at the Mojave rare earths project in California to more than 40 square kilometres with the staking of 249 additional claims.

The new ground abuts the company’s existing tenure adjacent to claims owned by US-based MP Materials, including the Mountain Pass mine—North America’s only producing rare earths mine and processing facility.

The additional claims strengthen Locksley’s competitive positioning within one of the most prospective critical minerals regions in the US, and provide it with a broader platform to advance new exploration and development opportunities.

Expanded Regional Exploration

Locksley has elected to accelerate and expand its exploration activities in the region to focus on existing antimony and rare earths prospects and target additional commodities identified across the new claims.

One priority area will be a substantial historical shaft (with an estimated depth of more than 15 metres) the company discovered during a recent surface geological and structural mapping campaign at Mojave.

The shaft’s vein orientation strikes north-to-northeast and is similar to that at the Desert antimony prospect, supporting the developing geological interpretation of multiple north-to-northeast striking structures across the project.

The company has since submitted the grab samples it collected from the prospect for laboratory analysis.

Favourable Claims Geology

Locksley’s new southeast claims encompass the favourable geology that hosts the Mountain Pass mine and carbonatites.

The northern claims are 3 kilometres along strike from Dateline Resources’ (ASX: DTR) Colosseum gold project, and the US geochemical database indicates polymetallic and precious metals occurrences in the adjoining area.

Importantly, several of the new claims directly adjoin the Mountain Pass larger claim package, underlining the strategic significance of Locksley’s footprint within the Mojave Corridor.

This positioning enhances the potential for exploration discovery and long-term commercialisation pathways, including downstream processing partnerships in line with US government priorities for supply chain resilience.

Strategic Material Enhancement

Locksley technical director Julian Woodcock said the expanded landholding would materially enhance the company’s strategic presence in the region.

“With additional ground abutting our existing claims and adjoining the Mountain Pass larger claim package, we are exceptionally well-positioned to advance a diversified pipeline of exploration and downstream opportunities across antimony, rare earths, other critical minerals, and precious metals potential,” he said.

The company has now completed its claim-staking activities and initiated the filing process in anticipation of receiving mineral rights.

Brokers and Analysts Visit

Locksley recently hosted a site visit at the Mojave project for a group of brokers and analysts, providing them with first-hand exposure to the scale of the expanded tenure and planned drilling activities at the Desert antimony mine and the El Campo rare earths prospect.

The visit underscored strong geological potential across the company’s project portfolio and highlighted its commitment to advancing exploration and development activities in the critical minerals hub.

“With the US government increasingly focused on securing domestic supply chains for critical minerals, Locksley is well placed to deliver a mine-to-market solution for antimony and rare earths,” chair Pat Burke said.
