Farabantourou Project – Barani East
- Extensively drilled out by Hyundai and Desert Gold
- Initial indicated and inferred resources reported for Barani East
- The deepest intersect of mineralisation at Barani-East was made at a depth of 120m whilst the
deepest end-of-hole reached 190m terminating within oxidised material, suggesting the oxidation zone may extend beyond 200m
Barani East mineral resource statement was made by Minxcon Consulting, November 2015. This resource statement was made in compliance with the specifications set out by the Canadian Code for reporting of resources and reserves as prescribed in the National Instrument 43-101.

Metallurgy Test
- Metallurgy – early results identify >90% recoverable by CIL,
- Gravity Concentration and Cyanide Leaching Pilot testing completed in 2014.
Number Concentration Step Description Result 1 Semi-batch Knelson Knelson concentration of -2 mm material 40.3% gold recovery was achieved
- n the minus 2 mm material
2 CVD Knelson CVD on semi-batch Knelson tails Mass pull of 11.2% at a recovery of 46.1% 3 Spirals Spiral processing of CVD concentrate Mass pull of 21.6% at recovery of 61.8% gold 4 High intensity leach Leaching of spiral and CVD concentrate Gold recovery of 93.4% after 24 hours 5 Normal leach Normal leaching on CVD tails Gold recovery of 55% after 24 hours
Based on this testwork, the following processing steps were envisaged:

- Crushing of scrubber oversize with the product recycled to scrubber;
- Semi-batch Knelson processing of scrubber undersize;
- CVD Knelson and spirals processing of semi-batch tails;
- High-intensity leaching of CVD/spiral concentrate; and
- Deposition of CVD/spiral and high intensity leach tails onto a dedicated tailings storage facility
(“TSF”).
