TRES-OR (GHANA) LIMITED GOLD PROCESSING PLANT OPERATIONAL

Tres-Or Resources Ltd. has completed fabrication on the gold recovery plant built for its operations in Ghana, West Africa. Tres-Or (Ghana) Ltd. provides mining and related services in connection with the Agudee gold project, a group of concessions held by a local syndicate of companies located in the Atwina Mpanua district of the Ashanti region in Central Ghana (see Stockwatch Sept. 14, 2009). Tres-Or Ghana and its contractors, Oasis Engineering Ltd., have completed assembling a 200-tonne-per-hour alluvial gold plant recovery system on the Agudee project site. Testing of the component motors, water system and electrical systems is complete.

The gold-bearing gravels (ore) are processed and concentrated on the barge. Gold is mechanically separated and concentrated and the remaining gravel or tailings are discharged from the rear of the barge while the excavator extracts and expands ore from the front of the barge. Gold-bearing gravels are fed into the feeder hopper at the front of the plant and tailings are discharged from the rear of the barge. For a continuous mining process ore is fed to the hopper with the barge moving forward as the gravels in the canal are mined to bedrock. Using this method the ore pit is constantly moving forward and filling the pond behind, effectively reclaiming the mined ground as it moves forward. Operating costs are much reduced because trucks for ore delivery, and tailings disposal, are not required with this method of alluvial mining. The "floater" plant leaves a very small environmental footprint, as well as being a cost effective way of processing ore and eliminating separate tailings disposal. No chemicals or mercury are used in the recovery process.

Testing confirms up to 95-per-cent mechanical recovery of gold which averages 20 carats to 22 carats from the source. Final gold recovery from concentrate using gravity feed systems for the mineral table circuit is fully operational.
