Simba Mines Inc. Completes Bulk Sampling and Testwork Aug 8, 2005 8:00:00 AM BAY CITY, MI and TORONTO -- (MARKET WIRE) -- 08/08/05 -- Simba Mines Inc. (OTC: SBAMF). Simba advises that 900 kgs of oxide ore from the copper ore outcrop have been sent to a specialist laboratory in Western Australia for metallurgical testing.
The material is now being analyzed to confirm copper recovery and reagent consumption and determine preliminary design parameters for the heap leach via column leach testwork.
The samples were selected in accordance with protocols agreed with the metallurgical consultants designed to verify the results of the earlier drilling program. Each sampling location was located by GPS for incorporation into Simba's 3D model.
The bulk samples of oxide ore represent 20% of the ore body. Planning has commenced for the recovery of a bulk sample of the nonoxidised ore representing the remaining 80% of the orebody: this will be extracted through the excavation of a small opencast pit.
Relogging, resampling and surveying have been completed successfully. Simba's exploration team has also completed the location and verification of all the original Peres trenches. This information has allowed reconfiguration of the Peres survey to a modern United Transverse Mercator grid.
About Simba
Simba holds through its subsidiaries, an 80% interest in the Cachoeiras de Binga licence in Angola, covering 3615 sq. km in Angola, through its wholly owned subsidiary Sociedade Mineira Simba Jamba LDA. Work to date has established a measured and inferred resource of 58.1 million tonnes at 2.14% copper which is a contained copper resource of 1.3+ million tonnes. The sharing split is Simba 80% and Angolan nationals 20%.
Mining of the resources will be undertaken through conventional heap leaching plus solvent extraction electro mining SXEW to produce LME grade copper cathode.
Initial plant production capacity is planned to be 20,000 tonnes per annum (approximately 44 million lbs) with capital costs estimated at US $35 million. Following upgrading confirmation of the geological resource, it is anticipated that the plant capacity will be increased in Year 3 to 40,000 - 50,000 tonnes per annum (approximately 88 - 110 million lbs of copper). The mine is located near the coast with much infrastructure already in place.
