Contract miningSouth Africa

A premier contract mining partner for safe, technology enabled underground operations, precision blasting and sustainable site reclamation.

The work, chapter by chapter

Mining is done by people.

Every tonne that leaves a mine has passed through somebody's hands. A crew secured the ground above it. A team planned the blast that freed it. Somebody swept the panel so that none of it was left behind.

RIG Mining is that somebody. Wholly owned by RIHM Investment Group, we are a services partner focused on safe, efficient and responsible operations. We combine operational expertise, modern equipment and digital innovation to support mine performance and resource recovery.

01Ground support and rehabilitation

  • An underground gallery cut through dark rock, lit from the far end
  • A tunnel with support frames standing along one wall
  • A haulage carrying pipes and cables along the rock, with water on the floor
  • Rail tracks running along an underground haulage

Nothing moves until the ground is safe.

Before a single tonne is hauled, the excavation has to be made secure. Our crews install rock bolts, anchors, mesh, lacing, elongates, steel sets and shotcrete to patterns approved by the rock engineer.

The same teams bring tired workings back into service, rehabilitating declines, cross cuts, return airways and primary haulages so that production can return.

02Precision blasting and mine development

Controlled energy, planned to the last detail.

Reef and waste development, redevelopment blasting in stalled panels, and controlled slyping to clear hanging wall and sidewall. Each blast is designed in software, timed for the rock it will meet and watched by seismic monitoring.

The aim is fragmentation that keeps processing costs low, with no disturbance to the people, buildings and ecosystems nearby.

StandardFragmentation and safety focus

  • 01

    Technical expertise

    Certified technicians and engineers, using controlled methods matched to the geology.

  • 02

    Innovative solutions

    Blast design software, seismic monitoring and predictive analytics.

  • 03

    Safety standards

    Extensive safety plans, training programmes and a zero incident focus.

  • 04

    Operational efficiency

    Optimal fragmentation and a fast response that cuts time lost between blasts.

  • 05

    Environmental stewardship

    Dust suppression during blasting and rehabilitation of blasted sites.

  • 06

    Equipment and technology

    Modern, well maintained equipment chosen for reliability.

03Vamping, sweeping and ore recovery

What was left behind still has value.

Vamping and sweeping recover residual ore, broken rock and fines from active and mined out panels. It is careful, physical work, and it turns ground that was written off into tonnes on the belt.

The same crews clear mud, desilt sumps, wash down with high pressure water and handle hazardous waste, leaving every panel clean and safe.

StandardOre recovery focus

  • A loader and trucks moving red ore in a yard

04Stockpile management

  • A bulldozer shaping a stockpile, seen from directly above
  • Excavators working coloured ore, seen from the air

Know what is on the ground.

Ore that has been mined and moved still has to be counted. We monitor and manage stockpiles with drone technology and predictive analytics, so the volumes on the ground are known and accounted for.

It gives planners a figure they can trust and takes the guesswork out of reconciliation.

05Environmental reclamation

Leave the land in working order.

Reclamation keeps the environmental impact of mining to a minimum and returns mined land to useful purposes. We restore ecosystems, bring back native plants and animals, and improve soil structure and pH.

Erosion control and drainage management keep the land stable and the water clean, and the work meets the statutory obligations that every mine carries.

StandardEnvironmental compliance

  1. 01

    Conservation of natural resources

    Natural ecosystems restored on land that was mined, including plants, animals, water and soil.

  2. 02

    Erosion control and drainage

    Erosion reduced and drainage improved to keep land stable and water clean.

  3. 03

    Restoration of soil quality

    Fertility rebuilt with organic material, better soil structure and controlled pH.

  4. 04

    Community empowerment

    Jobs, tourism potential and a better quality of life for the people living nearby.

  5. 05

    Compliance with regulations

    Mining companies carry statutory obligations. We help our partners meet them.

Technology enabled. People led.

Technology tells us what is happening. People decide what to do about it.

Every tool we bring to a site is there to make a crew safer and a decision better. That is why our monitoring, our planning and our training are built around the people doing the work.
