Capabilities

Five disciplines.
Audit-grade output.

From greenfield reconnaissance to grade control and compliance audits — every Optimine service is built for Namibian ground conditions and Southern African reporting standards.

01 / Service

Exploration Drilling

Diamond core programmes that read the rock.

Optimine runs surface and deep diamond core programmes across Namibia and the wider Southern African region. From greenfield reconnaissance to brownfield resource definition, we deliver core that geologists can build models on.

Our crews are drilled in chain-of-custody sampling, oriented core, and structural logging support — the work that turns metres into a defensible NI43-101 or JORC report.

RC Drilling

Reverse Circulation. Speed without compromise.

RC is where Optimine moves fast. Our multi-purpose rigs and crew rotations are built to keep penetration rates high while protecting sample integrity through every metre.

Cyclones are tuned, splitters calibrated, and chip trays logged digitally on the bench — so the laboratory receives representative pulps and the geologist gets a record they can defend.

On-site sample security
Grade-control optimised

Underground Drilling

Below the surface, on plan.

Underground programmes demand crews who think before they collar. Optimine pairs compact rigs with experienced drillers to extend ore bodies, infill resources, and de-risk extraction in active workings.

We integrate directly with mine ventilation, traffic, and blasting plans — so the rig is a partner on the level, not a bottleneck.

Operational Optimisation

Squeeze cost out, push throughput up.

Optimine started in iron and steel. We bring that heavy-industry discipline to mining operations — reviewing logistics, maintenance, and procurement chains end-to-end.

The deliverable is not a slide deck. It is reduced downtime, practical contract terms, and a maintenance regime your site teams can actually run.

QAQC & Compliance

NI43-101 & JORC, audit-ready.

A professional geologist oversees every Optimine QAQC programme. Standards, blanks and duplicates are inserted on a documented schedule, laboratory turnaround is tracked, and umpire laboratories are engaged on critical batches.

Our registered engineers convert and independently certify data outputs — so you get a fully defensible resource statement without engaging an external Competent Person.
