ROK Resources Inc. reported significant advancements and milestones in its lithium project: (i) successful results from a direct lithium extraction pilot project, (ii) successful production of pure battery grade lithium carbonate, (iii) expected timing of direct lithium extraction (DLE) field pilot, (iv) increased acreage in core operating area, and (v) update on the delivery of the Preliminary Economic Assessment (PEA). Direct Lithium Extraction: Pilot Test Results: The Company, through its ownership in Hub City Lithium, has successfully completed a large-scale pilot using the ILiAD DLE Platform developed by EnergySource Minerals (ESM), a privately held process technology company focusing on DLE in North America. The pilot, which processed 87,000 litres of brine from the Viewfield project area, successfully recovered 8,300 litres of concentrated eluent with an average lithium concentration of 1,430 mg/L(representing a 7.5x concentration from the feed brine provided).

An average lithium recovery of >90% and an impurity rejection rate of 99.62% were also verified by ESM. Hub City Lithium plans to ship the highly concentrated eluent to a 3rd party for refinement into battery grade lithium carbonate. Production of Battery Grade Lithium Carbonate: Hub City Lithium has confirmed successful production of 99.95% pure battery grade lithium carbonate, Hub City Lithium's first brine-to-battery-grade lithium carbonate production.

After direct lithium extraction, the eluent was refined into battery-grade chemicals at Saltworks' headquarters in British Columbia. This work was executed with Saltworks' proprietary concentrating, refining, and converting technology and expert technical team, employing novel technology that lowers the cost and greenhouse gas impact of lithium chemical production.
