• Field work is preceded by a reconnaissance survey of the area to preliminarily determine the scope of road construction and repair works, assess the condition of main access routes and existing mine workings, identify suitable conditions for establishing a base camp, determine water supply sources, and address other general organizational matters.

  • During the reconnaissance survey, the scope of mining and excavation works is determined, including the clearing of trenches, establishing trench alignments and drill-hole collars, and planning the routes for bulldozer cuts.
