ROK Resources Inc. announces record lithium concentrations

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.

Detailed Test Results

Electric Submersible Pump (“ESP“) Flow Test #1

Combined perforations from the Wymark D, E and F zones from 1,820 meters to 1,844 meters was flow tested for 41 hours at an average rate of 304 m3/day. The test resulted in a post clean up average of 215.3 mg/l.

Electric Submersible Pump Flow Test #2

Combined perforations from all zones from 1,820 meters to 1,911 meters were flow tested for 54.5 hours at an average rate of 550 m3/day. The test resulted in a post clean up average of 204.5 mg/l.
