Locksley Resources produces antimony concentrate to advance US supply ambition

• Locksley Resources produces antimony concentrate of 68.1%, well above marketable requirements of 55%.
• Concentrate achieved with only two tests, requiring minimal flowsheet development
• Next steps will involve bulk samples from underground workings and antimony ingot production

Special Report: Locksley Resources is another step closer to supplying antimony in its US mine-to-market strategy after producing high-grade concentrate from Desert antimony mine samples at its Mojave project in California.

LKY achieved a concentrate grading 68.1%, well in excess of the marketable requirement of 55%.

The concentrate was produced after just two preliminary tests, indicating mineralisation at Mojave project holds minimal impurities and will require minimal flowsheet development to maximise recoveries and grades.

Locksley Resources (ASX:LKY/OTCQB:LKYRF) said producing an antimony concentrate of this grade aligned the company with US government priorities for a fully integrated antimony supply chain.

With China restricting exports of antimony, demand for the critical mineral has grown rapidly due to its importance in defence and industrial applications.

Expanding metallurgical test program

With a market-grade antimony concentrate in hand, LKY is now looking to use QEMScan technology to develop an understanding of Mojave ore characteristics.

The company will collect a larger sample from the underground workings at the Desert antimony mine prospect to expand the metallurgical testwork.

Locksley will undertake flotation optimisation, gravity separation testwork and ore sorting with the goal of producing a larger volume of concentrate for use in pilot tests to produce ingots, oxide and trisulphide samples.

LKY will also provide a sample of concentrate to Rice University to begin Deep Eutectic Solvent extraction testwork using DeepSolv™ technology.

DeepSolv™ promises to address traditional issues with the dominant processing method, pyromet, which requires high energy inputs and creates high emissions.

LKY is developing DeepSolv™ alongside Rice University as a low energy input, high recovery percentage, ore-agnostic processing method capable of being scaled up easily via modular plants.
