Proposal Description
Raubex Construction (Pty) Ltd. intends to mine for Gravel (G5 &G7) and Stone Aggregate; Gravel (St) situated on the farm Rietfontein 156 (over a portion of the Remaining Extent), Heilbron district. The gravel/aggregate will be mined over the whole of the application area. The gravel reserve is situated over an old quarry (existing) which will be re-work to fully exploit the mineral reserve over this demarcated area. The gravel will be used in different facets of road construction and maintenance.
It is foreseen that the mineral is on average 12 meters deep, with an estimated overburden layer of 1.5m -2 m, which can be less in places as mining have already occurred over the terrain. This will be removed and place on the side of the pit to be used as safety berms and to keep surface water out of the pit. The identified and demarcated area, which are 5 hectares in total, includes the entire mining area. See Figure 2: Sketch plan. The gravel reserve on these 4 hectares (0,2 hectare for stockpile and plant area) is estimated at ±486’400m³.
The above area (existing mined quarry area) will be mined through opencast quarrying where the rock will be blasted where necessary and removed with an excavator onto a stockpile and fed by a frond end loader into the screening/crushing plant. A stockpile will be created at the screening plant and loaded on the trucks for transporting to the clients, on demand. It is envisaged that some of the gravel will be loaded directly onto the trucks without any processing. But most of the material produced will be used inhouse for road maintenance or construction projects. The mineral (gravel/stone) will either be load and hauled to end users or stockpiled on site to be moved as needed. The total estimated reserve of gravel/stone is ±486’400 m³ taken at a production rate of 4’000m³ a month, which will take 121 months to work the estimated reserve. The gravel/stone which is ±10m thick and the relatively medium production rate of this operation make these 4 hectares to be worked sustainable over more than five years.
