CobaltX holds 5 tenaments aound the Mnt Isa region - one of which is a stock pile of cobalt already out of the floor, previously mined in the early 1900's, cobalt grades believed to be in the ~3% range. Which is extremely high for cobalt grades, but was considered uneconimical back then.
Very cheap atm as the steams gone out in the minerals sector... makes for a cheap entry if your bullish on Cobalt and wanna take a position in a company with strong cobalt assets (also has lithium)
