Description of Activities to be followed Activities Description of phases Associated structures and infrastructures The Mineral Ingwe Plant Hire (Pty) Ltd intends to mine for Diamonds (Alluvial) (DA) situated on the Voetpaddrift 94 HP 94 HP (over a certain portion of remaining extent), Wolmaransstad district, and 5 hectares in total. See Appendix 1(a) – Locality Map for location of application area. The alluvial diamond gravel will be mined over the whole of the application area. The extend The gravel is on average 1 meter thick with a topsoil layer which varies between 300 and 500 millimeters. The area that was identified and demarcated is shown on the attached sketch plan. The gravel reserve on these 5 hectares is estimated at 75’000m³ or ± 84’975 tons and the total material to be moved is 75’000m³. Mining method The above area will be mined through opencast excavations where the topsoil will be stripped separately and stockpiled. The gravel is then removed with a 30 ton excavator and placed next to the excavation. A Front -end Loader takes the gravel to the 14 feet washing pan which is fed at a rate of 6m³ an hour, 48m³ a day and 5’280m³ a month. All the rough are first placed back into the bottom of the excavation, hereafter the puddle out of the pan is pumped directly back into the open excavation. After the puddle dried off, the topsoil is put back on top again. The excavations will be 60m in length 10m wide and ±1 meters deep on average. Only one excavation will be opened at a time. The total estimated reserve of gravel is 75’000m³ taken at a production rate of 5’280m³ a month it will take 24 months to work the estimated reserve of ±75’000m³. The production rate is taken at 5280m³/month. The gravel which is relatively shallow (1 meter) and the low production rate of the applicant make this 5 hectare to be worked sustainable over a period of two years. There will be a plant area with ablution facilities and roads to the excavations. Equipment to be used includes: * 1 x Frond end loader or 1 x Excavator; * 1 x Tipper truck * 1 x 14 feet washing pan * 1x Power plant * Pipes and water pump. The grade The grade of this gravel is estimated at 0.3 carat per 100 ton of gravel and $650 a carat, which can give 255 carats of diamonds. The small operation can last for 24 months and can be profitable.
