[{"type":"text","content":" GRAND BAIE, Mauritius, Feb. 20, 2020 (GLOBE NEWSWIRE) -- Alphamin Resources Corp. (AFM:TSXV, “Alphamin”, or the “Company”) wishes to highlight some of the key technical results of its newly filed updated NI 43-101 technical report for the Bisie Tin mine located in the Democratic Republic of Congo. The results include an improved Life of Mine profile and changes in Mineral Reserves and Resources. Updated Mineral Resources: Mineral Resources were updated as at 30 June 2019. The previous Mineral Resource estimate was as of 9 May 2016. The table below summarises the changes in Mineral Resources for the Mpama North orebody. Changes in Mineral Resource at 0.50% Sn Cut-Off Grade, 30 June 2019 Classification Quantity (Mt) Grade (%) Tin Content (kt) 2016 2019 2016 2019 2016 2019 Measured Resources 0.46 0.33 4.31 4.75 19.6 15.6 Indicated Resources 4.14 3.99 4.55 4.59 188.4 183.4 Inferred Resources 0.54 0.48 4.25 4.57 22.8 21.8 Total Mineral Resources 5.14 4.80 4.50 4.60 230.8 220.8 Percentage change -6.6% 2.3% -4.3% All tabulated data has been rounded and as a result minor computational errors may occur. Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability. Mineral Resources are reported inclusive of Mineral Reserves. Alphamin has an 80.75 percent interest in ABM. The Gross Mineral Resource for the Project is reported. 2019 figures reflect depletion by mining from mine surveys as at 30 June 2019 and an estimate of the extent of artisanal mining to 725 RL. The decrease of 10kt in contained tin is attributable as to 2.4t from depletion through mining activities by 30 June 2019 and 7.7t following a revised interpretation of the artisanal mining base. No other changes have been made to the Mineral Resource, no exploration data has been added to the database and cut-off grades have remained the same. Updated Mineral Reserves: Mineral Reserves were updated as at 31 December 2019 to take account of the revised Life of Mine (LOM) plan following a change in mining method from the previous Sub-Level Caving (SLC) mining method to Open Stoping with Hydraulic Backfill (LHS). The decision to transition from SLC to the LHS mining method was made to reduce safety and technical risks associated with SLC in the underground environment encountered at Mpama North. The previous Mineral Reserve estimate was as of 6 ...
