Montréal, Quebec–March 06, 2023 – Sama Resources Inc. (“Sama” or the “Company”) (TSX-V: SME; OTC-PK: SAMMF) is pleased to announce completion of the latest metallurgical test program applying a modified process flowsheet to its Samapleu-Grata nickel (“Ni”), copper (“Cu”), cobalt (“Co”) and platinum group elements (“PGE”) Project in Ivory Coast, West Africa. The latest metallurgical testwork comprised enhanced Locked Cycle Tests (“LCT”) on composites from the Samapleu Main and Grata deposits, and batch testing on a composite from the Samapleu Extension zone. This testwork was completed by Blue Coast Research Ltd (“BCR”), a leading metallurgical testing and consulting company based in Parksville, British Columbia.


“The metallurgical testing at Blue Coast Research continued improving the already excellent recoveries and concentrate grades using the Locked Cycle Tests. The high-grade nickel and copper concentrates are very attractive and of great value which could be further enhanced by the payable precious metals.” stated Dr. Marc-Antoine Audet, President & CEO of Sama Resources Inc.


A slightly refined version of the processing scheme described in the January 24, 2023 press release has now been applied to all three composites. This scheme relies entirely on flotation to produce direct saleable concentrates without the need for any further on-site metallurgy. The scheme is widely used in the industry and is relatively inexpensive. It is well-suited for application on remote mine sites.

The recent work culminated in locked cycle testing of the Grata and Samapleu Main composites. In these tests, both composites were subjected to the same scheme, and both responded similarly. This suggests material mined from both sources can be processed through the same plant and most likely can be blended.

Copper, nickel and cobalt results are highlighted below:

Copper concentrate Nickel concentrate
Grade, % Recovery, % Grade, % Recovery, %
Copper Nickel Cobalt Copper Nickel Cobalt Copper Nickel Cobalt Copper Nickel Cobalt
Samapleu Main Zone 26 1.2 0.05 83 3 3 1.6 13 0.5 9 67 51
Grata 27 1.1 0.04 88 4 4 1.3 13 0.5 6 72 61


Copper flotation yielded 83-88% copper recovery, to concentrates assaying 26-27% copper. Nickel and cobalt misplacement to the copper concentrate was 3-4%. Nickel flotation yielded 67-72% nickel recovery to concentrates assaying 13% nickel. Cobalt recoveries were 51% and 61% for the Samapleu Main and Grata composites respectively.

In both cases a combined 60% of the palladium was recovered to the copper and nickel concentrates, the majority being recovered to the nickel concentrate. The palladium grades are expected to yield attractive payment terms from smelters. Platinum grades should in most cases be high enough to attract some payment, with recoveries to both concentrates of 47% and 62% from the Samapleu Main and Grata composites. Gold may also attract a small pay from both copper concentrates:

Copper concentrate Nickel concentrate
Grade, % Recovery, % Grade, % Recovery, %
Platinum Palladium Gold Platinum Palladium Gold Platinum Palladium Gold Platinum Palladium Gold
Samapleu Main 1.8 6.4 1.4 12 19 26 2.8 7.6 0.3 35 41 10
Grata 1.1 7.3 1.2 22 23 43 1.5 8.7 0.3 40 37 12


The Samapleu Extension composite was also subjected to two batch tests using the chosen flowsheet, primarily to assess the applicability of the same flowsheet to this part of the resource. No locked cycle tests were run on this composite. The tests yielded very similar concentrate grades to the locked cycle tests, again with good selectivity evident between the copper and nickel concentrates. Recoveries were somewhat lower, whichcan be ascribed to the batch nature of the test, even in locked cycle mode copper and nickel recoveries are still expected to be lower for this material.

Key results are shown below:

Copper concentrate Nickel concentrate
Grade, % Recovery, % Grade, % Recovery, %
Copper Nickel Copper Nickel Copper Nickel Copper Nickel
Samapleu Extension Zone 28 0.8 67 1 2 16 8 48


The copper and nickel concentrates assayed 19 and 21 grams per tonne (“g/t”) combined Pt/Pd respectively. Platinum and palladium would both attract good payment terms from such concentrates, while gold, assaying 4 g/t, will attract good pay from the copper concentrate. Cobalt assayed 0.8% in the nickel concentrate. Recoveries of these minor metals are difficult to project from batch tests but like copper and nickel, appear somewhat lower for Samapleu Extension based on this composite.
