Orca Gold Block 14 ProjectWater
Sudan, North Africa
The Orca Gold Block 14 Project is located close to Sudan’s border with Egypt
GCS was initially appointed as the hydrogeological consultant to assist with groundwater exploration activities for the Pre-Feasibility Study in 2016. The study progresses to Definite Feasibility in 2017/2018. Exploration was carried out in Area 5 on the basis that two existing boreholes had for many years reliably supplied water. An airborne conductivity survey carried out by SkyTEM covering an area of 1080km² in conjunction with geological mapping.
Drilling of 17 exploration boreholes in Area 5 and four (4) test production boreholes commenced in April 2017 and was completed in September 2017. Groundwater was intersected at an average depth of 75m below surface or 437 meters above mean sea level (mamsl) and the main aquifer system (higher yielding zone) around 100m below surface or 410 mamsl. Static groundwater elevation is in the order of 443 mamsl. The main airlift yields ranged between 3.3l/s and 11.9l/s (the maximum flow measured by the V notch).
The aquifer contains 100 Million m³ in the Measured Resource category and a further 40 Million m³ in the Indicated Resource category.
