[{"type":"text","content":" VANCOUVER, British Columbia, July 05, 2018 (GLOBE NEWSWIRE) -- Monument Mining Limited (TSX-V:MMY) (FSE:D7Q1) “Monument” or the “Company” reports on progress made with the basic gold processing plant design and the Front End Engineering Design (“FEED”) for its Selinsing Gold Sulphide Project (“SGSP”) in Malaysia. Additional testwork programs from independent consultants have pushed out the completion date which is now aimed for mid-August, 2018. Process and Engineering Design The basic gold processing plant design and FEED form a major part of the Feasibility Study. It is aimed to convert the existing oxide gold treatment processing plant to a sulphide treatment gold processing plant. As a result, it would allow additional flotation process and BIOX® process to be added to the existing plant with certain alterations to the existing process. To date both design packages have been delivered for Monument’s review, subject to further optimization should it be required upon additional flotation test work. Basic Metallurgical Process Design The design of the new processing facilities featuring: flotation, BIOX® oxidation, counter current decantation, neutralisation and conventional CIL processing has now been completed by Orway Mineral Consultants (“Orway”) and delivered to Monument for review. CIL tailings will undergo conventional cyanide detoxification prior to the Activated Sludge Tailings Effluent Remediation (“ASTER™”) process. A water recovery thickener will recover the bulk of process water from flotation tailings, neutralisation and ASTER™ discharge. The thickener underflow will be pumped to the existing tailings storage facility (“TSF”). The BIOX® process is a patented technology for pre-treatment of sulphide-based refractory ores and concentrates ahead of a conventional cyanide leach for gold recovery. Outotec, the owner of the patent has produced an ASTER™ process design package for the biological destruction of residual cyanide and thiocyanate. Operation of the ASTER™ process, as successfully practised at the Runruno BIOX® plant in the Philippines, will provide clean water for milling and flotation and prevent the poisoning of the BIOX® microbes by cyanide compounds. FEED Contromation Energy Services (“CES”) has submitted the engineering design of the new processing facilities. The 3D model of the...
