This deposit has been known since 2010.
Non-JORC resource: 159mtn @ 1.045% nickel and 0.07% cobalt
Total limonite (high iron) and saprolite (low iron) resources were estimated at 159mtn @ 1.045% nickel and 0.07% cobalt at a specific gravity of 1.2 by Kaiser in 1993.
This is a historic estimate and is not a JORC compliant resource. Tropical laterite deposits Tropical laterite deposits such as those at San Jorge and Santa Isabel (Takata) have much more favourable metallurgical characteristics than “dry land” laterites.
This has seen development of many mining operations worldwide from Cuba in the west to Indonesia, New Caledonia, the Philippines and more recently, Papua New Guinea in the South Pacific. Tropical deposits offer a variety of development options ranging from direct shipment to smelters, high pressure acid leach (HPAL) processing, atmospheric leach processing and heap leach operations.

Yes, like I said low grade and rarely are nickel concentrate from laterite nickel ore suitable for EV battery which uses nickel sulphate (mainly from specific nickel sulphide concentrate).
