SUMMARY
• Geological and geomechanical examinations allow to define the
geological structure of the deposit more precisely.
• Mine layout designs are set up and based on geomechanical
reconnaissance and geological model of the deposit. This allows
to minimalize the risk of unexpected events, increase the
resource recovery ratio and allows to predtict the quality of output
material.
• Mine production schedules are made upon created mine layout
design and geological models.
