As briefly described in the Company's news release dated May 10, 2021, the Separation Rapids work program will be focused on geological mapping and geochemical sampling to follow up on new lithium pegmatite occurrences on the claims acquired in 2018 on the northwestern part of the property. A similar work program involving geochemical surveys and detailed geological mapping and sampling is planned for the Lilypad property with a focus on identifying additional cesium occurrences. Both programs are designed to identify new drill targets for a follow-up fall diamond drilling program.
