Locksley Resources Limited (OTCQB: LKYRF | ASX: LKY) has expanded its landholding in California’s Mojave Critical Minerals Corridor, staking 249 new claims and boosting its total to 491 exploration claims. The acreage adjoins MP Materials’ Mountain Pass Rare Earth Mine — the only rare earths producing mine in the U.S. — and secures ground rich in antimony, rare earth elements (REEs), and polymetallic prospects. This strategic expansion strengthens Locksley’s exploration pipeline and positions the company in one of North America’s most important critical minerals districts.
Dateline Resources Limited (OTCQB: DTREF | ASX: DTR) has launched an accelerated 10,000-metre drilling program at its 100%-owned Colosseum Gold-REE Project in San Bernardino County, California.

The site already hosts a 1.1 Moz gold resource, while new geophysical surveys identified high-priority REE and breccia pipe targets.
Power Metallic (OTCQB: PNPNF | TSXV: PNPN) remains a standout Canadian critical minerals exploration story, advancing a portfolio of gold, silver, nickel, copper, and platinum group metals (PGMs) assets vital to the global EV supply chain. The company’s projects are strategically aligned with surging demand for battery metals driven by electrification and clean energy mandates. A recent high-profile board appointment of former Canadian Minister of Energy & Natural Resources Seamus O’Regan Jr. has further strengthened market confidence and institutional visibility, positioning Power Metallic as an emerging contender in the next wave of battery metals development.
MineralRite Corporation (OTCID: RITE) achieved a major milestone as its shares were designated Penny Stock Exempt by OTC Markets. This status removes regulatory hurdles for penny stocks, simplifies investor access, and broadens the base of institutional investors and broker-dealers able to trade RITE. CEO James Burgauer described the designation as a transformational milestone, expected to reduce trading friction and enhance shareholder value.

Focused on clean water solutions and eco-friendly refining processes, Sidney is developing sustainable technologies designed to deliver both economic benefits and long-term environmental protection. The company emphasizes its broader vision to create a sustainable future through toxin-free mineral recovery and green innovation.
