VANCOUVER - Sarama Resources Ltd. ("Sarama" or the "Company") is pleased to announce that preliminary metallurgical testing at its flagship South Houndé Project in south-west Burkina Faso has returned encouraging results, indicating potential for heap leach processing of oxide mineralisation. Sarama is conducting the testwork to establish a range of alternatives for the development of the South Houndé Project, with the heap leach concept presenting an attractive low-cost alternative.

Highlights

  • Average gold extraction of 90.2% for oxide composite sample in intermittent bottle roll testwork1
  • Variability testwork on high-grade mineralisation samples returned an average extraction of 93.0%. Variability testwork on sediment-hosted mineralisation returned an average extraction of 75.4%. Both samples had low to moderate reagent consumptions1
  • Visual observations suggest that oxide material readily forms a stable feed when agglomerated with cement
  • Agglomeration testing indicates moderate cement requirements with 6-10kg/tonne addition rate yielding acceptable pellet strength and column slump levels2
  • Percolation testing indicates that high solution flow rates through the agglomerated product can be achieved
  • Column leach testing has commenced on composite sample using agglomeration with cement addition of 10kg/tonne
  • Oxide component of the Inferred Mineral Resource at South Houndé Project contains 298 koz of gold3

1. Samples control crushed to -25mm and -8mm screen sizes, prior to leaching by sodium-cyanide solution in intermittent bottle roll test over a 10 day period

2. <10% column height slump adopted as acceptable limit for 80mm diameter column with ~400mm charge height

3. 6.82 Mt @ 1.4 g/t Au for 298 koz reported above 0.4 g/t Au
