Heritage Cases

The prospecting area was identified through aerial photographs. The extent of the prospecting area will be 459.2268 hectares. Information from Geological surveys will be used in order to determine where the test pits will take place. This will in turn help to determine the boundaries of the proposed prospecting area for more detailed surveying. PHASE 1 Geological desktop studies and surveys in order to try and identify the gravel run. Various geological maps and instruments will used to identify if alluvial gravel deposits might be present on the application area. 6 Months are needed for Phase 1 PHASE 2 In Phase 2 test pits will be made (3m x 2 m x ± 2.5m deep), on a grid of 100 x 100meters and where necessary on a 50 x 50 meters grid where the gravel outcrops. This test pits are made with a 30 ton excavator, to determine if any diamond bearing gravel does occur. This test pits will be closed up immediately before the excavator move on to the next one. It is envisaged that 100 test pits will be made over the application area. 6 Months are needed for Phase 2. Expected disturbance: 3m x 2m = 6m2 x 100 = 600m2 (0.06 ha). PHASE 3 A bulk sample to a total of 23’040m³ gravel will be taken, consisting of trenches 10 x 30 x ± 2.5m (deep). With the average gravel depth of ±2.5m, (1.5m thickness) 10 trenches will be needed to get to 23’040m³. These trenches will be ±100 m apart from each other; the envisaged positions of the trenches will be indicated on a map at the end of Phase 2. The topsoil will be removed with an excavator and stored on a separate stockpile for rehabilitation purposes. The overburden will then be stripped and placed on the side of the excavation. The gravel is then removed with an excavator and transported with a frond-end loader to the washing plant consisting of a 14 feet pan. The puddle is washed directly back into the excavation. The rough out of the pan will also be put directly back into the open excavations. The concentrate out of the pan will be sorted by hand where the diamonds will be recovered and the grade of the prospecting area determined. 24 Months are needed for Phase 3. Expected disturbance: 10m x 30m = 300m2 x 10 = 3’000m2 (0.3 ha). Thus total disturbance over the life of the prospecting right (3 years) are: 0.06 ha + 0.3 ha = 0.36 ha
