13.0 MINERAL PROCESSING AND METALLURGICAL TESTING Two historical metallurgical test programs and one current program were used for reference in the design of the process facilities in this PEA. The reports for the 1988 test work by Lakefield, Inco Tech, and CANMET were unavailable. However, the prefeasibility report from WGM was available and contained the results from the test work as described below. The G&T technical report from May 2011 was reviewed and the pertinent results are presented below. The latest program results from SGS are also presented in this section. The design of the process was based on these test results and the estimated flotation grades and recoveries. 13.1 L AKEFIE L D , I NCO T ECH, AND CANMET – 1998 Drill core rejects from the 1987 drilling program were tested in 1988 and 1989 at Lakefield, Inco Tech, and CANMET to investigate the metallurgical behaviour and obtain data on the mineralization. This test work was summarized in the WGM 1989 prefeasibility report. Additional test work was done at CANMET in the 1990s and was summarized in Cabri et al. (1993). Analysis of preliminary metallurgical tests in early 1988 indicated that a bulk concentrate of about 5% copper and 4% nickel would achieve recoveries up to 95% of the copper, 85% of the nickel, 80% of the platinum and 80% of the palladium. This was produced from a feed whose analysis was 0.87% copper, 0.65% nickel, 1.03 g/t platinum and 0.75 g/t palladium. Additional samples of material from the Wellgreen deposit were tested during the second half of 1988 at Lakefield. Lower grade materials included in these samples more closely approximated the material that could be anticipated from an open pit operation. The major improvement to the results was the inclusion of high speed conditioning prior to the cleaning step of the bulk concentrate. This resulted in an increase in the grade of concentrates with an increase in recovery. The results from these flotation tests are shown in Table 13.1. The results from testing lower grade material utilizing the high speed conditioning are shown in Table 13.2.
