I believe this statement is bring misread“Several lab tests yielded a portion of recovered nickel with concentrate grades in excess of 30%. The next phases of work will focus on continued flowsheet optimization and developing a broad base of test samples. These are essential given the wide range of mineralogy in these types of deposits which typically results in nickel recoveries for a specific block ranging from 10-15% to as much as 60%.”
what i'm reading we did get portion of recovered nickel in excess of 30% but our average is 26% for the overall M&I resource .. with 41% grades for HGC but the higher grade HGC is 31% nickel in concentrates for the HGC in the M&I category or for most of the first minning sequence of 280 million tons..the sulfur is helpfull for heat while combined with oxygen in the smelting process, it's a fuel
now the wide range of mineralogy in these types of deposits is a broad statement for all deposits not singling CNC deposits wich can range in specific blocks from 10-15% to as much as 60%
Fe or iron recoveries are decent
Cobalt is low but as stated expected as thesesamples contain primarily heazlewoodite (rather than pentlandite) which contains little cobalt. PGM assays are pending
