Vancouver, B.C., May 15, 2019, Serengeti Resources Inc. (SIR: TSX-V) announces the results of the first of a number of metallurgical tests being conducted on samples from the Kwanika Project which is controlled by Kwanika Copper Corporation (“KCC”), a private company jointly owned by Serengeti Resources Inc. (65%) and Posco International Corporation (35%). This test work is continuing, and full results will be released in the Pre-Feasibility Study scheduled for completion in Q3, 2019.
The metallurgical test program is being conducted to investigate metallurgical performances of various mineral samples to a conventional flowsheet. The locked cycle test (LCT) results show that the sample constructed from the proposed open pit area responded well to the conventional processing flowsheet tested. On average, approximately 88.3% of the copper and 73.5% of the gold are recovered into a Cu-Au concentrate containing approximately 25.1% Cu and 23.4 g/t Au. Impurity levels of the concentrate are low.
The processing flowsheet includes rougher and scavenger flotation followed by regrinding of the rougher concentrate and four stages of cleaner flotation. The primary grind size was targeted at 80% passing 75 µm. A number of samples are being tested in the program including:
- Three composite samples, representing the proposed open pit, west underground area and east underground area comprised of coarse assay reject material from the 2018 drill program.
- Approximately 15 variability samples, representing various head grade, spatial location and lithological variations and sample type, including coarse assay rejects vs drill core.
The pair of test results from duplicate samples from the open pit composite sample are summarized in the table below.
The Au-Cu concentrate produced from the LCT 1 test was assayed for main impurities which may affect concentrate quality. The assay indicates that in general the impurity levels of the concentrate are low. Most of the impurity levels are expected to be much lower than the penalty thresholds specified by most of the smelters, excluding fluorine which may be close or slightly higher than the requirement of some smelters.
The test work is ongoing on the two underground master composite samples and the variability test samples. In general, the two underground samples show similar metallurgical responses when they are tested using batch open circuit test procedure. The LCT tests have been arranged to verify the metallurgical performances of the two underground composite samples.
The metallurgical test work is being conducted by Metallurgical Division, Bureau Veritas Commodities Canada Ltd., located in Richmond, British Columbia and supervised by Dr. John Huang, a Senior Metallurgist with Tetra Tech Canada Inc.
