The Pandora prospect was discovered while on aerial reconnaissance in February 2012. It lies in the Oklila exploration permit. Rock-chip, chip-channel sampling and detailed geological mapping, revealed the presence of a major high-grade epithermal quartz vein system. Extensive channel sampling shows persistence of grade over a 2.6 km strike length of the Pandora vein (including Pandora and Pandora South). The vein is up to 10m wide, and averages more than two meters width over the 2.6km strike length. Grades vary from 5ppb Au to 54.5g/t Au (RX08032).

Highlights from the chip-channels include:
P-Ch-17 with 1.9m @20.35g/t Au,
P-Ch-23 with 3.44m @ 7.77g/t Au,
P-Ch-29 with 8.1m @ 2.04g/t Au,
PS-Ch-04 with 5.0m @ 10.87g/t Au,
PS-Ch-06 with 2.35m @ 13.17g/t Au.

Further work identified several sub-parallel veins linked to Pandora, the new veins are the Pyrrha and Castalia veins. Pyrrha is a narrow vein (up to 1.7m) outcropping along a 1km strike with highlight chip-channels such as: Pb-Ch-08 with 0.85m@14.23g/t Au, Pb-Ch-17 with 1.7m@6g/t Au, also high grade grab samples such as RX06380 @71.6g/t Au. The Castalia vein outcrop along 600m before going under basalt cover (highlight sample: RX08156 @3.4g/t Au).

A mineralized set of narrow veins along the Pandora vein was identified as fractured accommodation zones on the major fault and named Thyia zone. The veins are multiple in a short area and strike E-W instead of the usual NW-SE rift axis trend.

The Pandora vein is believed to be linked to the major vein found beyond the Thyia zone in the North-western part. This low grade structure identified as Pandora Far West outcrop for another 3km before going under basalt cover from the mountain range of the Gaggadé horst. Highlight samples includes NW-Ch-13 with 0.6m@4.8g/t Au and grab sample up to 4.9g/t Au (RX08118).

The 2.5km of high grade veins formed by the Pandora and Pandora South vein set is a high priority target. Since 2012, 1036 samples including rock and soil were assayed with extensive geochemistry studies including major and rare multi-element. In terms of grade, continuity and width, the Pandora vein is unmatched by any other prospect in the country.

A diamond drilling programme is being prepared for Q4 2016.
