 Type of Mining: Alluvial diamond prospecting, using geological desktop study, test pits and bulk sampling.
 Mineral Resource: Diamonds Alluvial (DA) & Diamonds (in Kimberlite).
 Prospecting Process:
Phase 1: Field Mapping Geological desktop studies will initially be done to confirm the area of interest. Further field work, testing and mapping of the possible reserve and gravel runs to confirm the areas for test pits. This will mostly be done by a professional geologist assigned to the proposed project. 3 Months will be required for the assessments by geologist.
Phase 2: Test pits will be made (3m x 2 m x ± 2.5m deep), on a grid of 100 x 100 meters and where necessary on a 50 x 50 meters grid where the gravel outcrops. These test pits are made with a 30 ton excavator, to determine if any diamond bearing gravel does occur. This test pits will be closed immediately before the excavator move on to the next one. They will be examined visually, and a picking sample will be taken if necessary. It is envisaged that 100 test pits will be excavated, and 6 months are needed for Phase 2.
Phase 3 Bulk Sampling To determine if the gravel does have diamonds the gravel needs to be taken out and tested, by putting it through the washing process. Trenching will be used to open the gravel to get a representative sample for testing. The trenches will be ±10 x 60 x ± 3.5 m (deep). In one trench ± 2100m³ (± 2400 ton) gravel will be exposed depending on the gravel depth and tested with 14 feet washing pan at a rate of 8m³ (10 ton) an hour it all depends on the depth of the gravel, which amounts to 1’280m3 per month treated through the washing pan. The total prospecting area is 774.1337 hectares, thus it is anticipated that because of the variable gravel depth, a bulk sample of ±30’720m³ over the total area is needed to get a representative sample. 1’280m3 (Gravel) will be tested per month by making trenches on different locations over the whole prospecting area, where the possibility of diamond bearing gravel was identified with the test pits in 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 14 feet pan. All processing will be done on site and the pubble will be washed directly back into the excavation. The rough out of the pan and oversize stones 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. Taken at an 8 hour working day, 5 days a week and 20 days a month, the applicant will be able to process 1’280m³ a month, depending on variables such as breakages and weather conditions. The moving of the pan and processing of 30’720m³ will take about 24 months (2 years) for Phase 3, which will result in ±14 trenches to be excavated and rehabilitated over the 774.1337 hectares. See Figure 4 for Ore Processing Flow Sheet.
Phase 4: Final Geological Report after completion of all test pits evaluation and final processing of all bulk samples the qualified geologist will assemble all test results and evaluated the finding with the area applied for. A final geological report will be compiled to bear the results of all test work done and how feasible further applications for renewal or migration to a mining right will be. 3 Months is needed for Phase 4
