The scavenger tail and 1 st cleaner tail of the LCT-1 were submitted to Terra mineralogical services Inc. for
PGE mineralogy. PGE minerals predominately occur as liberated particles in the Ni 1 st cleaner tail. In
contrast, only minor amounts of liberated grains (all of them sperrylite) are deported to the Ni scavenger
tail, whereas the bulk of PGE minerals reports to this sample as inclusions or intergrown with gangue
minerals. Most of the non-liberated PGE minerals occurring in the Ni 1 st Cleaner Tail are intergrown with
pyrrhotite and only minor amounts are associated with magnetite or silicate gangue. In the Nickel
scavenger tail, two-thirds of the PGE minerals are also intergrown with sulphide (chiefly pyrrhotite), yet
approximately 21% are also associated with silicate gangue. It is note worthy that almost half of the Pt
losses (mineral sperrylite) is as small liberated particles. PGE mineralogy results are presented in
Appendix G.
7. Concentrate Analysis
The potential for the deposit is known to contain various impurity elements which may result in penalties
or bonus payments at the smelter. In order to complete the study, full multi-element analysis was
conducted on concentrates produced from each locked cycle test. 7e and Co ICP-Scan for the LCT-1
products were also conducted. Tables 29-32 list the results. The concentration of various elements in
locked cycle test concentrates from master composite feed material are presented, mainly as ICP results,
in Appendix B.
