Services that keep an open-pit operation moving.

Contract Mining

Nsimbi Mining Services partners with mining companies to provide contract mining services, delivering tailored solutions, expert personnel, and cutting-edge equipment for all aspects of mining operations.

• Drilling services — precision-focused exploration and production drilling.
• Load and haul — efficient material movement with reliable heavy-duty fleets.

Load and Haul Services

Our load and haul services provide complete support for the transportation of materials within your mining operation. We offer a wide range of heavy-duty equipment, from haul trucks to loaders, designed to optimize the efficiency and safety of material movement.

Blast Hole Drilling

We drill accurately placed, correctly sized blast holes for the explosive charges that break rock ahead of loading. Hole diameter, depth, spacing and burden are set to the bench design, so fragmentation stays controlled and the loaders, haul trucks and crushers that follow can run efficiently.

Exploration Drilling

We provide exploration drilling to sample the ground ahead of mine planning, using diamond core drilling for continuous, intact rock samples and reverse circulation (RC) drilling for faster, lower-cost chip sampling at depth. Core drilling gives a solid cylindrical sample suited to detailed geological logging and structural analysis, while RC drilling delivers crushed cuttings from a known depth, suited to grade control and resource definition over larger areas.

Borehole Drilling

We drill boreholes for water supply and for pit dewatering, lowering the water table and controlling groundwater inflow so bench and highwall stability is not compromised as an open pit deepens and expands. Dewatering boreholes range from deep, large-diameter production wells to shallower drainage holes around the pit perimeter.

Dewatering

We design and run the pumping systems that keep an open pit dry as it deepens, matching the method to the inflow: sump pumping around the excavation for straightforward drainage, wellpoint systems where a shallow water table needs to be lowered evenly across an area, and deep well systems, each fitted with its own submersible pump, where a larger volume needs to be drawn down ahead of the working face.

Mining Equipment & Technical Support

We supply certified, quality-assured equipment and drilling tools that enhance safety and improve operational productivity, guaranteeing reliability and durability even in the toughest environments. Rental units are also available whilst repairs are carried out on existing machinery, to ensure minimal loss of production time.

• Quick-ship — fast-moving spares dispatched against urgent breakdowns.
• On-site — parts delivered and fitted at your operation.
• Bulk order — scheduled resupply of consumables, oils and drilling tools.
