Locksley Resources (ASX:LKY | OTCQX:LKYRF | FSE:X5L) extends high grade silver corridor at Mojave Project

Locksley Resources has reported the delineation of a high grade mineralised silver corridor at its Mojave Project in California, following an extensive program of surface reconnaissance and rock chip sampling across the North Block.

The results represent a material extension of known mineralisation and add further technical depth to a project that already hosts antimony and rare earth element targets in a strategically important U.S. jurisdiction.

Highlights

• Rock chip sampling returned assays of up to 409 g/t Ag from the Mojave Project North Block

• The interpreted mineralised corridor extends almost 3 km from the Silver Prospect

• Associated base metal mineralisation was recorded, including up to 4.2% Cu, 1.5% Pb and 1.5% Zn

• Twelve rock chip samples exceeded 30 g/t Ag

• Mineralisation is interpreted as a polymetallic quartz vein system trending northwest to southeast

The reported results are drawn from a reconnaissance and surface sampling campaign designed to test the strike extent of high grade silver mineralisation first identified in late 2024.

That work has now confirmed a consistent northwest to southeast oriented mineralised corridor extending from the Silver Prospect, through the historic Hendricks Shaft area, and approximately 600 m further to the east southeast, resulting in an interpreted strike length of almost 3 km.

Sampling across the North Block has been extensive, with a total of 398 rock chip samples collected to date.

Approximately 260 of those samples were taken along the interpreted mineralised corridor between the Desert Antimony Mine and areas extending up to 5.6 km to the southeast.

The mineralisation style observed across the corridor is described as polymetallic quartz veining, with several high grade samples exhibiting gossanous selvages and boxwork textures, which are interpreted as indicators of weathered sulphide rich mineralisation at surface.

Visual copper mineralisation, including malachite staining within outcropping veins at historic workings, provides further confirmation of base metal enrichment within the broader silver system.

From a strategic perspective, the silver corridor is positioned by management as complementary to Locksley’s core focus on antimony development at Mojave.

The project also includes rare earth element targets and hosts the historic Desert Antimony Mine, which last operated in 1937, with the combination of silver, base metals, antimony and rare earths within a single project area underpinning Mojave’s emerging status as a multi commodity exploration asset.

Commenting on the results, Managing Director and CEO Kerrie Matthews said

“Defining a 3 km mineralised trend with surface results of up to 409 g/t silver and 1.5% copper is a highly encouraging outcome. Importantly, this discovery complements our core antimony development strategy and gives exposure as a diversified U.S. critical minerals company, providing shareholders with upside to precious metals, base metals, and strategic minerals within a single, high quality project area.”

Locksley has outlined a systematic next phase of work, including detailed geological mapping between the Silver Prospect and the newly defined southeastern extension, petrological and geochemical studies to better understand mineralisation timing and associations, and an assessment of geophysical survey options such as VLF EM, IP and electromagnetic methods.

The stated aim is to refine structural interpretations and delineate high priority drill ready targets along the corridor.

In a broader industry context, the identification of an extensive high grade silver corridor within the Mojave Project adds further technical and strategic optionality to Locksley’s U.S. asset base.

While exploration remains at a surface evaluation stage, the scale and grade of the reported mineralisation underline the geological potential of the North Block and reinforce Mojave’s relevance within the evolving U.S. critical and precious metals landscape.
