Name of the Project
Okvau gold project.

Location
Mondulkiri province, eastern Cambodia.

Project Owner/s
Renaissance Minerals, a wholly owned subsidiary of ASX-listed Emerald Resources.

Project Description
Okvau has an independent Joint Ore Reserves Committee-compliant initial ore reserve of 14.3-million tonnes at 2 g/t gold for 907 000 oz at an average all-in sustaining cost of $754/oz over an initial seven-year life-of-mine.

The project involves the development of an openpit and a two-million-tonne-a-year processing plant to produce 106 000 oz/y of gold on average.

The deposit will be mined using conventional openpit mining methods from one pit at a relatively constant mining rate. Mining will be undertaken by drilling and blasting ore and waste, with loading and hauling undertaken by a mining contractor.

The proposed processing plant will use a single-stage crushing circuit and semiautogenous grinding milling circuit, sulphide flotation and regrind mill, followed by conventional cyanide leaching.

Tailings from the process plant will be disposed of in a dedicated tailings storage facility.
