Kenai Resources Ltd.: Trial Gold Mining Planned at Sao Chico, Brazil
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/02/12 -- Kenai Resources Ltd. (TSX VENTURE: KAI) ("Kenai") is pleased to announce that it is planning trial mining at the Sao Chico gold project in northern Brazil following an internal review of the recent high grade gold drill results in the central Waldimiro Structure, underground mine planning and the results of metallurgical testwork.
An application is being prepared and will be lodged during April for a GUIA(1) (Guia de Utilizacao, ie trial mining use permit) licence to mine and process an initial high grade underground tonnage. Subject to finance and permitting, production using mechanised mining and highly selective shrinkage stoping will commence at the maximum 50,000 underground tons of high grade gold bearing material permitted under the GUIA in the first quarter of 2013. The high grade gold potential of the Waldimiro Structure can be seen in the longitudinal section in Figure 1 and from the data in Table 1.
The decision to plan for underground GUIA production also followed discussions with a neighbouring gold project, to consider processing the high grade Sao Chico underground tonnage at the existing mill facilities to produce gold dore. That project is fully permitted, including tailings storage facilities. A detailed review of available plant capacity and possible flow sheet modifications will be required prior to a final decision being made.
Metallurgical testwork results have been received from SGS Lakefield laboratories, from several unoxidised samples taken from the underground Waldimiro Drive. Gold recoveries of 99% were obtained from three different methods, ie whole ore cyanidation leaching, gravity separation and flotation, and gravity separation and cyanidation. From 30 samples, an average in-situ density of 2.71 tonnes per cubic meter was estimated.
Ongoing drilling at the project is also planned in conjunction with trial mining. As fully detailed in the news release of November 29th, 2011, Kenai believes that the Sao Chico project is highly prospective. The Sao Chico project is located within the wider AP 12836 exploration licence covering 1,436 hectares, with the AP now held in the name of Gold Aura do Brasil Mineracao Ltda ("GOAB").

Kenai's NI 43-101 Technical Report on the Sao Chico project is now being updated that will include an initial mineral resource estimate for the project. Ground based geophysics is planned in the Sao Chico project area for delineation of additional drilling targets.
A feasibility study of the trial mining has not been completed and there is no certainty the proposed operation will be economically viable. A PEA (Preliminary Economic Assessment) report is being prepared for the initial 50,000 ton GUIA trial mining operation. The PEA will consider priorities for further core drilling to improve knowledge of the potential of the two recently discovered high grade gold zones at the Sao Chico deposit, and the as yet untested potential along strike and to the north of the demonstrated high grade zones.
Background to the Sao Chico, Brazil project
The Sao Chico gold project is located along a prominent NW-SE trend, the Tapajos Gold Trend, which is the most mineralized zone within the Tapajos Mineral Field in central-northern Brazil. The Tapajos field was the site of the biggest gold rush in Brazilian history in the late 1970's and 1980s when approximately 500,000 garimpeiros (artisanal miners) rushed to the area to exploit extensive areas of newly discovered alluvial gold. Approximately 20 to 30 million ounces of gold (unofficial government figures) were produced from these operations before the easily won alluvial gold deposits were largely depleted. The garimpeiros have little expertise in underground mining and environmental considerations and were thus urged by the government to consolidate their small claims and form joint ventures with established mining companies. The area has had little exploration by modern exploration methods compared to other equivalent gold fields in the world.
