Locksley Resources has completed a high-resolution underground light detection and ranging (LiDAR) survey at the Desert Antimony Mine (DAM) prospect, part of its Mojave project in San Bernardino County, California, US.  

The survey produced a detailed 3D representation of the historic mine workings, creating a framework to guide resource drilling and future mine redevelopment planning.

Results confirm approximately 236m of underground development distributed across four distinct levels, extending through a strike length of around 130m.  

The 3D data clearly outlines three previously mined areas, identified through open stopes of the mineralised quartz-carbonate-stibnite veins that align with known historical production.  

This information is expected to support refinement of geological interpretation and underpin Locksley Resources’ upcoming targeted drilling campaign. 

Locksley managing director and CEO Kerrie Matthews said “The LiDAR dataset has given us an increased level of geological detail and understanding of historical mining at the DAM that didn’t exist before.

“The survey has confirmed the position of the historically mined stibnite-bearing veins and the quality of this data materially enhances our ability to progress drilling design with far greater precision. Importantly, this work also underpins our broader Mine-to-Metal US growth strategy by supporting a fully domestic antimony supply chain in the US.” 

The completion of the LiDAR survey marks a significant milestone in Locksley Resources’ execution of its US critical minerals strategy. 

The survey serves as a framework as the company progresses towards the redevelopment of the DAM. 

Further steps include conducting detailed geological mapping of the underground workings at DAM, scheduled for November, and integrating the LiDAR survey data into the 3D geological model to support preparation of a Joint Ore Reserves Committee (JORC) exploration target.  

Additionally, Locksley Resources will evaluate ground conditions within the historic workings to enable detailed underground sampling. 

The adoption of LiDAR technology is a key elememt of Locksley Resources’ data-driven, accelerated mine redevelopment strategy aimed at re-establishing domestic US antimony supply innovation. 

Earlier in September, the company added 249 additional claims to its landholding of more than 40km² of highly prospective critical minerals in California’s Mojave region.
