ROK Resources Inc. announced the successful completion of a multi-layer perforation and swab test of a wellbore strategically located on one of Hub City Lithium Corp. Subsurface Crown Mineral Dispositions located in the Mansur Area of Saskatchewan. Third-party laboratory testing returned lithium concentrations in the Duperow formation of up to 148 mg/l. The Test Results should allow for the development of a three-layer lithium brine project with high lithium concentrations expected throughout the target intervals.

The Company expects to develop the three individual zones utilizing horizontal wellbores. ROK, as manager of operations to Hub City Lithium, is currently finalizing a 43-101 resource report for the Mansur Area which is expected to be completed during First Quarter 2023. In parallel with the Resource Report the Company has begun working on the development plan and Preliminary Economic Assessment (" PEA ") which it expects to complete during Second Quarter 2023.

In addition, the Company is currently working with a third-party direct lithium extraction technology provider who is expected to process the Company's brine through a pilot test as early as Quarter 1 2023, which will assist in the PEA. The Company continues to work on testing and evaluating its Viewfield Area which is thirty-five miles southeast of the Mansur Area and has a footprint of 47,360 net acres of land.
