  Excellent Recoveries Confirm Heap Leach Potential

West African Resources Limited (Perth, Australia ASX, TSXV: WAF) is pleased to report preliminary metallurgical test work results from the Mankarga 5 Deposit located on the Tanlouka Permit, part of its Boulsa Project, in Burkina Faso.


Gold recoveries confirm heap leach potential of oxide ore at the Mankarga 5 deposit, Boulsa Gold Project, Burkina Faso. Gold recoveries of up to 91.5% and averaging 82.5% in coarse feed size heap leach amenability cyanidation test work after 120 hours. Many samples still leaching after 120 hours, higher leach extractions would have been achieved if the test duration was extended. Very low cyanide consumption of 0.3-0.4kg/t. Rapid leach kinetics with average gold extraction more than 50% after eight hours. Mankarga 5 deposit contains near-surface oxide and transitional Indicated Resources (at a 0.5 g/t cut-off) estimated at 6.6 million tonnes at a grade of 1.2g/t gold containing 252,000 ounces gold; and oxide and transitional Inferred Resources (at a 0.5 g/t cut-off) estimated at approximately 2.7 million tonnes grading 0.9 g/t gold containing 75,000 ounces gold (ASX: 14/4/14). Scoping study for a low-cost heap leach project, targeting near term cash-flow from Mankarga 5 deposit, to be released later this quarter. West African aims to be a +50,000oz per annum gold producer within two years, subject to study outcomes.
