[{"type":"text","content":"\n Further re [Preliminary Economic Assessment]BKM Copper Deposit Preliminary Economic Assessment UpdateVANCOUVER, British Columbia, March 02, 2016 (GLOBE NEWSWIRE) -- Asiamet Resources Limited (\"ARS\" or the \"Company\") is pleased to advise that a Preliminary Economic Assessment (\"PEA\") on the Beruang Kanan Main (\"BKM\") deposit within the Company's 100% owned KSK Contract of Work in Kalimantan, Indonesia, is advancing well in line with plan and budget. The independent PEA is expected to be delivered at the end of the first quarter this year.The PEA is a conceptual study evaluating the potential economic viability of developing an open pit mine and heap leach SX-EW processing facility to treat near surface copper resources delineated in the 2015 BKM Resource estimate (ARS Announcement October 21, 2015). ARS estimates that approximately 25% of global copper supply is produced using the heap leach, solvent extraction and electro-winning (\"SX-EW\") process and the opportunity for ARS to assess the application of this proven technology to produce copper metal at the BKM site is expected to greatly enhance the attractiveness of the project.Significant progress is being made across all of the PEA inputs with positive results reporting from each of the study areas in line with the Company's expectations. Progress for each of the PEA component study areas is summarized as follows:Metallurgy and Resources - Recent studies have significantly advanced the metallurgical understanding of the deposit. Sequential copper assaying was completed on 1,918 drill samples to characterize the distribution of leachable copper mineralization within the preliminary open pit design. The metallurgical testing program comprises both acid only and bacterially assisted acid bottle rolls, and short acid column tests. The test work program is being undertaken in Core Resources laboratory in Brisbane, and the extended leaching tests are providing encouraging results from both the acid only and bacterial assisted methods. High short term (55 day) recoveries of +70% have been obtained from the acid only leaching. Bacterial leach tests are continuing with recoveries to date consistent with expectations given copper head grade and leach residence time. Leach tests are showing mild acid production in the latter part of the leach, a factor which shou...
