| Popis: |
In terms of Bulgaria's physiographic division, the prospect area is located within the East Rhodopean sub-region, which is part of the East Rhodopean-Strandzha region. The Ada Tepe prospect, which is under consideration, is located approximately 3 km southwest of the town of Krumovgrad and 1 km west of the Krumovitsa River. The Krumovgrad district is characterised by a moderate hilly to low-mountainous topography. The "Khan Krum" field includes four sections - Ada Tepe, Kaklitsa, Sarnak and Skalak. On this stage mining works are developed only in the area of Ada Tepe. The ore at Ada Tepe will be open-pit mined. The mining method will be a conventional open cut drill, blast, load and haul operation. Processing of ore to concentrate is done after primary crushing and grinding within the gold-silver concentrate production facility (process plant) with fully enclosed transfer. Flotation using reagents and dewatering produce the end product – gold-silver concentrate. All rock material without economic gold and silver values and therefore classified as mining waste, that includes rock materials, waste from enrichment, soil, ores and low grade ores are stored in an Integrated Mining Waste Facility (IMWF) located approximately 200 m south-southeast of the open pit. The IMWF is designed to store both dewatered process tailings and waste rock from mining. |
