NOT FOR DISTRIBUTION TO THE U.S. NEWSWIRE OR FOR DISSEMINATION IN THE UNITED STATES

REGINA, SK / ACCESSWIRE / February 21, 2023 / ROK Resources Inc. ("ROK" or the "Company") (TSXV:ROK)(TSXV:ROK.WT) is pleased to announce the successful drilling and multi-layer perforation and flow test of a wellbore strategically located on one of Hub City Lithium Corp. ("Hub City Lithium") Subsurface Crown Mineral Dispositions located in the Viewfield Area of Saskatchewan. Third-party laboratory testing returned lithium concentrations in the Duperow formation of up to 259 mg/l (the "Test Results"). According to public records, these Test Results are the highest lithium concentrations ever recorded in a brine in Canada.

Test Results: 2-22-7-9W2M

Note: Independent laboratory testing was conducted by Isobrine Solutions (Edmonton, Alberta)

Cam Taylor, CEO of ROK, commented "The elevated lithium concentrations and high flow rates across six zones make this a very exciting lithium brine well for ROK and for the Saskatchewan and Canadian Lithium industries. Based on public data these are the highest lithium concentrations tested in Canada to date. Seeing such high lithium concentrations in six zones provides us with a second project area for development alongside the previously announced multi-zone Mansur area project."

Next Steps

The Company will drill additional test wells within the area as part of its continued evaluation. These high lithium concentrations in six target intervals suggest the potential for a six-layer lithium brine project. Further work will be done to identify surface drilling pads large enough to allow for the production of multiple horizontal wellbores within the pilot project area.

A 43-101 resource report ("Resource Report") for the Mansur area has now been expanded to include the Viewfield area and is expected to be completed during Q1 2023. In parallel with the Resource Report the Company has begun working on the Mansur development plan and Preliminary Economic Assessment ("PEA") which it expects to complete during Q2 2023. Further, the Company plans to do additional drilling in the Viewfield area as part of the data gathering towards a second PEA dedicated to the Viewfield area which is expected in Q4 2023.
