TORONTO, ONTARIO--(Marketwired - Jun 2, 2014) - Desert Gold Ventures Inc. (TSX VENTURE:DAU) (the "Company" or "Desert Gold") is pleased to record extensive metallurgical test work conducted on bulk mining samples from the recently drilled and sampled Barani East Gold Deposit (the "Deposit") indicates gold recoveries up to 85%. The company is currently engaged in a feasibility study to support fundraising for the development of a mine on the deposit.
Process Design
A two ton bulk sample of ore collected from the Barani east prospect was submitted to Peacocke Simpson & Associates (Pty) Ltd's minerals processing laboratory in Harare, Zimbabwe for bulk metallurgical work.
The company has commissioned an engineering design team from Appropriate Process Technologies (Pty) Ltd (Johannesburg, South Africa) ("APT") for plant design. APT specialises in the manufacturing of modular mineral processing plants and are designing a plant to optimise the economic exploitation of the resource. The latest tests indicate that a low capital cost plant comprising a wash and screen (2 mm) circuit, with minor crushing, feeding to a Knelson gravity concentrator will recover 40.3% of the gold. The tailings from the Knelson concentrator were fed to a Knelson continuous variable discharge concentrator (CVD) from which concentrates with a mass yield of approximately 11% were subjected to a cyanide leach, which resulted in an additional 25% of the gold to be recovered. Although this process, in aggregate, generates a lower recovery of the gold (65%) compared to other processing alternatives, this configuration requires the least capital investment, being some 80% cheaper than the alternative maximum recovery design plan, and having the lowest operating costs. Tailings with the unrecovered gold will be stockpiled as an asset for later re-treatment.
About the Project
The Barani East Gold Deposit occurs on the Desert Gold's Farabantourou Permit located in Western Mali. The permit falls on the Senegal-Mali Fault Zone ("SMFZ"), 40km south of Sadiola Mine and 50km north of the Loulou-Gounkoto mine complex (Fig. 1). Both these mines are on the SMFZ.
Barani East is the first of 6 prospects with proven gold mineralization expected to be developed by Desert Gold on the permit. The project has been drilled to a depth of 120m with mineralization open to depth in the southern part of the deposit (Fig. 2).

The Resource
The company has focused drilling on the Barani East prospect and has completed a maiden mineral resource estimate, which indicates a total of 108,100 oz gold in the indicated and inferred categories with average grades of 2.50 g/t gold at a cut-off value of 1.0 g/t gold. (Table 1). This resource is currently defined to a maximum depth of 120 m below surface over a strike length of 400m. The deposit is tabular, mineralisation varying in thickness from 4.5m to 15m, and dipping to the east between 45deg and 60deg. The gold mineralisation is associated with quartz hematite rocks and kaolinite veins within siltstone and shale.
Farabantourou Strategy
Desert Gold's Farabantourou permit strategy is to develop the other 5 known gold prospects to a mineral resource definition stage similar to what has been achieved at Barani East. Funding for drilling on the other 5 prospects will be provided out of mining revenue from a low cost opencast mining operation on Barani East. A feasibility study is being concluded to define the CAPEX and related operational cost associated with a potential mining operation to extract the resource as defined from surface. High grade Au intersections of 9.99g/t over 4m and 8.60g/t over 3.5m at 120m vertical depth show potential for developing an underground resource at Barani East following the exploitation of the open pit resource.
