[{"type":"text","content":" MONTREAL, March 14, 2018 (GLOBE NEWSWIRE) -- Sama Resources Inc. (TSXV:SME) (“SME” or the “Company”) today reports that SRG Graphite Inc. (“SRG”) has today announced progress in the development of its mineral processing flowsheet designed in conjunction with DRA Americas and SGS Canada. Additionally, SRG has received positive testwork results on the expandable properties of its graphite flakes from the Lola deposit. Sama holds a control position in SRG of 24,658,267 shares representing 43.93% of the issued and outstanding shares of SRG and is considered an insider for reporting purposes. The key result highlights are as follows: Preliminary testwork suggests wet scrubbing as an alternative to traditional grinding is possible, which would reduce capital and operating costs while promoting flake size preservation. Ongoing testwork suggests the developed flowsheet would allow for 95%-98% Cg concentrate to be produced over all size fractions. Performed expandability testwork on +50mesh and +80mesh graphite concentrate obtained 350ml/g and 300ml/g, respectively, well over industry requirements. Scrubbing TestworkA first round of test work is ongoing at SGS Canada Lakefield, with focus on the grinding method, flotation and flowsheet development. SGS Canada conducted positive preliminary testwork, using rotary scrubbing for mineral size reduction and graphite liberation. These results support the hypothesis that, for SRG Graphite’s weathered mineralized material, wet scrubbing alone, instead of the conventional primary grinding, is sufficient to produce the particle size required and ensure graphite liberation for flotation. The wet scrubbing method promotes graphite flake size preservation during mineral size reduction. “The Installation of rotary scrubbing circuit presents a great opportunity for the reduction in capital and operating cost, as rotary scrubbing equipment is typically less expensive and consumes less electric power compared to conventional (SAG, rod or ball mill) grinding circuit employed for the same feed rate and processing duty” said Volodymyr Liskovych, P.Eng. Senior Process Engineer, DRA. Flowsheet RefinementIn addition to the ongoing testwork for SRG’s preliminary economic assessment, SGS processed a 120kg bulk sample of material from the Lola deposit using its latest flowsheet. The resulting grade c...
