Monument Updates on Intec Pilot Plant Commissioning at Selinsing
Vancouver, B.C., February 3, 2016, Monument Mining Limited (TSX-V: MMY and FSE: 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.
A drill team has been deployed to the field to collect representative ore samples for the second pilot plant run. Those samples will be concentrated by flotation and fed into the pilot plant for testing. The results of this second pilot plant run are anticipated to be available in May 2016 for Orway to complete economic analysis of the Intec technology based sulphide gold recovery process. The economic analysis will be incorporated into an updated NI43-101 technical report, targeted for release by June, 2016.
In conjunction with the Intec trial test work, Selinsing has commenced flotation work to produce fresh concentrate samples for bench-scale testing ahead of the second pilot plant run. Flotation results to date are shown below:
|Ore Sample||Recovery, %||Calculated Head|
|Au||S||Au, g/t||S, %|
|BR South B1||97.87||98.40||2.54||2.64|
|BR South B2||97.71||99.59||2.98||1.73|
|BR Central B1||97.58||99.47||2.34||1.36|
- BR South B1 and BR South B2 are two separate representative grade samples of the Buffalo Reef South area of the orebody.
- BR Central B1 is one type (stibnite-rich) of two types of ore in the Buffalo Reef Central area of the orebody.
