SlimTrades 300 ppm Lithium CutoffYes, very good observation Slimtrades about 300 ppm cutoff.
Most of what Spearmint is drilling through "Continuous" Lithium clay material down to 260 feet will most likely be "ore" grade material above 500 PPM.
Very little cost of Blasting materials, no Rockbreaker needed, very little wear & tear on truck boxes, No costly capital & operating Crushing plant required, Musk already on it and working on the most cost effective "alternative" processing methods of Lithium clay processing, a benefit to All Clayton Valley developers.
So, all SPMT needs to do is continue with well planned drilling, building the resource inventory and initiate preliminary mineralogy and metallurgical test work.
The SPMT Lithium clays should exhibit similar characterization as the Cypress/Noram Lithium material.
Noram and Cypress have already done most of the metallurgical leg work so SPMT benefits greatly from that work, that is, what has been learned about the most cost effective process to generate battery grade Lithium.
