Highlights

  • Mojave tenure exceeds 40 sq km in California's Mojave Desert, directly adjacent to MP Materials' world-class Mountain Pass rare earth mine.
  • Initial rock-chip sampling returns high-grade antimony and rare earth assays across El Campo and North Desert structural corridors.
  • Tottenham Copper-Gold Project in NSW's Cobar region adds Australian VMS base metals exposure.
  • LKY shares closed at $0.064, market cap $24.05 million, down 87.07% over 12 months amid significant equity dilution.

In a single staking campaign, Locksley Resources (ASX:LKY) assembled 40 square kilometres of California ground next to the United States' only operating rare earth mine — and then found antimony on it.

Aggressive Expansion Across California's Mojave Belt

Locksley Resources has substantially grown its mineral tenure across the Mojave Critical Minerals Project, situated in the Mojave Desert mining corridor of southern California in immediate geological proximity to MP Materials' world-class Mountain Pass rare earth mine. Locksley has staked hundreds of contiguous federal mineral claims, assembling a district-scale landholding exceeding 40 square kilometres. Intensive field geological campaigns are targeting high-grade antimony and heavy rare earth element mineralisation across the El Campo, North Desert, and prospective structural corridors.

The strategic expansion into high-grade antimony comes at a critical geopolitical inflection point. Stringent global trade restrictions and international export bans have triggered historic supply deficits in the physical antimony market, prompting US industrial and defence agencies to aggressively prioritise domestic supply. Initial surface reconnaissance and rock-chip sampling across the Mojave tenure have returned exceptionally high-grade antimony and rare earth assays.

US Defence Metals and Magnet Rare Earths

Antimony is indispensable for national defence munitions, armour-piercing ammunition, night-vision equipment, infrared sensors, and solar glass manufacturing. With the United States currently reliant on foreign imports for virtually all its antimony requirements, establishing commercial domestic resources carries immense strategic and commercial value.

The Mojave project also hosts high-grade concentrations of magnet rare earth oxides including neodymium, praseodymium, dysprosium, and terbium — vital components in high-performance permanent magnets for electric vehicle drivetrains and wind turbines. Complementing the American critical minerals strategy, Locksley retains 100% of the Greater Tottenham Copper-Gold Project in the Cobar region of New South Wales, providing exposure to high-grade volcanic-hosted massive sulphide copper-gold deposits in Australia.

Market Valuation and Renewed Investor Interest

Shares in Locksley Resources settled at $0.064 on 2 October 2026, easing $0.001 or 1.54% across an intraday band of $0.062 to $0.065 on heavy trading turnover of 1,683,793 shares. The company commands an equity market capitalisation of $24.05 million. Over the preceding 12 months, the stock declined 87.07%, reflecting substantial equity dilution and broad-based market scepticism toward early-stage critical minerals exploration.

However, recent heavy trading liquidity demonstrates renewed investor interest following the company's aggressive antimony targeting. Locksley has maintained a disciplined, focused expenditure strategy directing available capital toward ground validation, environmental permitting, and active community engagement in California.

Path to First Drill Hole

Locksley's immediate operational roadmap centres on securing Plan of Operations approvals from the US Bureau of Land Management to permit maiden diamond core drilling at priority antimony and rare earth prospects across the Mojave Project. Commencement of drilling will represent a defining technical milestone for the company.

Concurrently, systematic geochemical trenching and ground geophysical surveys across the El Campo prospect are refining drill targets. Management is also engaging with US governmental critical minerals funding agencies and commercial processing groups to explore strategic development partnerships.

Cross-Border Exploration Risks

Permitting mineral exploration and mining operations in California involves rigorous environmental compliance review under state and federal frameworks, which can result in lengthy administrative delays. As a company without commercial mining revenues, Locksley depends on external equity capital markets to fund intensive drilling programmes, exposing shareholders to potential dilution.

Project economics also remain vulnerable to volatility in international antimony and rare earth pricing, as well as complex metallurgical processing requirements for extracting pure critical metal concentrates from mixed mineralisation.
