Monument Updates on Intec Pilot Plant Commissioning at Selinsing
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb. 3, 2016) - Monument Mining Limited (TSX VENTURE:MMY)(FRANKFURT:D7Q1) "Monument" or the "Company" reports that it is pleased to announce the results from the first trial of the Intec pilot plant commissioning program. As announced in the September 24, 2015 news release, the Company completed the construction of the Intec Pilot Plant and placed it into commissioning at the Selinsing gold mine site in Malaysia. The pilot plant was built as a part of the Intec Trial Testing Program to exploit Intec's sulphide dissolution and gold recovery technology using the existing Selinsing Gold Processing Plant under the Interim Intec license.
During the first trial, the Intec pilot plant was successfully commissioned achieving "steady state" for 7 days where various parameters were tested using different sulphide feed stock materials drawn from selected ore samples in Buffalo Reef and Selinsing Deeps. The purpose of the pilot run was to demonstrate two main aspects of the process: bench scale batch test work results can be duplicated in a continuous flow process and the process can be successfully scaled-up. The following table shows the results of gold extraction tests on Intec leach residue samples.

The second trial of the pilot plant commissioning will now commence to test the response of ores containing varying amounts of pyrite and arsenopyrite using sulphide ores from Buffalo Reef and Selinsing Deeps. It will allow the effects on overall gold recovery of sulphide pre-concentration by gravity and flotation methods to be compared. The second trial is being carried out following recommendations by, and agreement with Orway Mineral Consultants (WA) Pty Ltd of Perth, Western Australia who are engaged by Monument to oversee and report on the pilot plant operation.
