Ann: Drilling Program Commences at Mt Cobalt, page-14

That's typically the case with laterite ore types. What we have at Pembroke is sulphides

Point of difference is with laterites it's easy to dig it up (ore is usually shallow) but a lot more complex to process. In laterite deposits cobalt is usually a credit mineral attached to Nickel and copper deposits. An average size laterite processing plant is priced between $800-1000m

With sulphides, the ore is basically in ready end product state (minus dilution and impurities). Sulphide deposits are usually deep and hence harder to extract. The processing is a lot simpler because they are already in end chemical state. Just need to crush, clean, concentrate. And off to market for sale.

Some of the biggest Nickel deposits in the world (eg Norilsk) are sulphides but not many have been found and exploited in recent times. ANW and Pembroke/Mt Cobalt (if found significant) could in fact be of world significance and much easier/quicker/cheaper to exploit. plus of course we're in a safe mining jurisdiction with predictable mining code at a time when these metals are in high demand.
