Schedule to align the deposit
Schedule of construction
- Reaching a base ramp of about 2100 m in length to a depth of about 410 m.
- At the end of the ramp, the immediate transition into the deposit 4 and thus the recording of tungsten and flourspar extraction takes place.
- Establishment of the connection between base ramp and exploratory shaft (weather connection and escape route).
- Parallel to the ore production in the deposit 4, a secondary ramp in the deposit 5 (tin) and then in the deposit 3 is produced in order to mine later both deposites at the same time.
- Build the technical infrastructure at the bottom of the base ramp.
These includes, among others:
- primary crusher,
- Building the dewatering and water treatment plants as well Workshops and material stores.
Building of the technical infrastructure on surface (sewage treatment plant, rainwater treatment, process water treatment and electrical connection).
- Building sanitary tract and administrative facility as well as mine rescue site.
- Construction of the treatment plant on surface.
