Amara expects to announce a significant increase on the existing Yaoure Central resource (249,000 ounces - 4.9Mt at 1.6g/t(ii)) in Q1 2013 based on the results of the 2011/2012 drilling campaign.
Phase one of a metallurgical test campaign to understand the leaching kinetics of the mineralised material at Yaoure has been completed where variability leach and CIL recoveries averaged well in excess of 90%. The results also confirmed the non-refractory nature of the gold mineralisation and will be reported in full with the resource update.
Phase two of the test work, which is designed to identify the optimal processing route, will include tests such as heavy medium separation, gravity, flotation, the effect of grind and simulated heap leach via coarse bottle rolls. This test programme is expected to be completed by the end of May 2013 and the results will be announced thereafter.
This report includes certain "forward-looking information" within the meaning of applicable Canadian securities legislation.
All statements other than statements of historical fact included in this report, including, without limitation, the positioning of the Company for future success, statements regarding exploration, drilling results, resource calculations and potential future production at Yaoure, and future capital plans and objectives of Amara, are forward-looking information that involve various risks and uncertainties. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from Amara's expectations include, among others, the Company's ability to delineate sufficient sulphide resources for the development of a CIL/CIP operation, risks related to international operations, the actual results of current exploration and drilling activities, changes in project parameters as plans continue to be refined as well as future price of gold. Although Amara has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Amara does not undertake to update any forward-looking statements that are included herein, except in accordance with applicable securities laws.
The diamond drilling programme at Yaoure was undertaken by two independent drilling contractors. Drill cores for assaying were taken at a maximum of two metre intervals, typically one metre, and were cut with a diamond saw with one-half of the core placed in sealed bags. The core samples were sent to the Intertek sample preparation facility in Yamoussoukro, Cote d'Ivoire, prior to fire assay, mainly at Intertek Minerals Ltd in Accra, Ghana, but also at the SGS laboratory in Tarkwa, Ghana). In addition, two batches of samples (two holes) were sent to Bureau Veritas in Abidjan, Cote d'Ivoire, for sample preparation and fire assay. The core samples were crushed down to minus 2 mm, with half the sample then being pulverised down to 85% passing 75 microns, prior to analysis for gold by fire assay using a 50 g sample. As part of the Company's QA/QC procedures, internationally recognised standards, duplicates and blanks were inserted. The laboratories used are independent of the Company.
