West African Resources Excellent Gold Recoveries Confirm Further Potential at Boulsa Gold Project
09.07.2014 | ABN Newswire
Perth, Australia (ABN Newswire) - West African Resources Ltd. (ASX:WAF) (CVE: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.Managing Director Richard Hyde commented on the metallurgical test work:
"These excellent results demonstrate further project potential after the heap leach starter project which will focus on generating cash flow from the oxide material of the Mankarga 5 deposit. We look forward to reporting the results of the scoping study heap leach starter project by the end of this month."
The results from the 100(mu)m bottle roll tests were conducted across all ore types and are very positive, showing high recoveries and low cyanide consumption (Table 1 below and also in link below). These results represent potential recoveries from conventional milling and CIL processing. The test work program is continuing and results will be reported as they are received.

Near-term Strategy
The Company aims to be a +50,000oz per annum gold producer within two years via a low-cost heap leach starter project at the Mankarga 5 deposit, subject to study outcomes. West African has secured a second-hand 1.6Mtpa heap leach plant as part of its plan to fast-track development of Mankarga 5. Detailed metallurgical test work is underway on Mankarga 5 drill core in Perth. Results of this test work will be incorporated into the scoping study which will be released by the end of July. The proposed project development schedule for Mankarga 5 is shown in link below.
