Sarama Resources Acquires the Bondi Gold Deposit in Burkina Faso From Orezone Gold - Seite 2
Location & Strategic Fit
The Bondi gold deposit is located within the 168km² Djarkadougou exploration property (the "Property") which lies adjacent to Sarama's 2.1Moz3,4 Au South Houndé Project in south western Burkina Faso (refer Figures 1 and 2). Bobo-Dioulasso, Burkina Faso's second largest city, is located approximately 75km to the west and is linked by a paved highway that transects the Property. The mineral resources within the South Houndé and Karankasso Projects are each located approximately 30km (straight line) from Bondi, presenting an opportunity to ultimately combine the three deposits by trucking feed to a central processing facility.
Metallurgical testwork by Sarama at the South Houndé Project has identified several processing flowsheets including heap leaching for oxide material and a staged tank-based plant for hard rock material. The combination of Bondi and the South Houndé Project puts Sarama in a position where, building on recent exploration success, it can contemplate development options via several possible processing routes.
Exploration & Mineral Resources Estimate
Since 1998, Orezone and others have conducted systematic exploration on the Property, including approximately 80,000m drilling (reverse circulation and diamond core), which culminated in the delineation of sub-vertical, shear-zone hosted mineralisation along a strike length of 4.1km. The mineralised lodes are up to 24m in width and have been intersected to a vertical depth of approximately 320m by the deepest drilling (refer Figures 3 and 4). Gold is associated with disseminated sulphides (predominantly pyrite) in quartz veins and veinlets that are hosted by quartz-feldspar-porphyry, sheared arenite-argillite and mafic dykes. Alteration envelopes of varying composition are also present.
In 2009, Orezone published a Mineral Resource for Bondi (see note on Historical Estimate below), reported at a cut-off grade of 0.5g/t Au2, comprising:
- 4.1Mt @ 2.1g/t Au for 282,000 oz Au (measured and indicated); and
- 2.5Mt @ 1.8g/t Au for 150,000 oz Au (inferred)
This Historical Estimate included a high-grade component (reported at a cut-off grade of 2.0g/t Au) of 1.4Mt @ 4.2g/t for 186,000 oz Au (measured and indicated)2, which reflects several shoot-controlled, high-grade zones within the lodes.
