Operational advisory
Review of drilling practices, planning and workflow to lift output and reduce the hidden costs that build up across a shift.
Drilling Consultancy
Top-Hammer & DTH Drilling Consultancy
Technical and practical expertise that helps mining and drilling contractors in East Africa drill faster, run rigs longer and lower their cost per metre.
Overview
Hands-on advice rooted in real rig experience
MMST is a mining consultancy specialised in top-hammer and down-the-hole (DTH) drilling. We combine technical knowledge with practical, on-the-ground experience to solve the problems that quietly erode productivity — premature consumable wear, poor hole quality, avoidable downtime and unplanned breakdowns.
We work alongside your team and your machines, from Pantera and Flexiroc to SmartRoc, Ranger and Atlas Copco rigs, to find practical gains you can sustain. Our recommendations are designed to be acted on by the people who run the rigs every day, not left on a shelf.

Scope of work
What we advise on
From day-to-day rig performance to long-term fleet decisions, our consultancy covers the full drilling lifecycle.
Drilling optimisation
Tuning of feed, rotation, percussion and flushing parameters to improve penetration rate, hole quality and consumable life.
Rig troubleshooting
Root-cause diagnosis of recurring faults, drifter problems and breakdowns so you fix the cause, not just the symptom.
Technical training
Practical coaching for operators and maintenance crews on best-practice drilling, daily checks and rig care.
Rig selection
Independent guidance on choosing the right top-hammer or DTH rig and configuration for your ground conditions and targets.
Cost & consumable strategy
Advice on bits, rods, shanks and parts strategy to balance consumable spend against productivity and rig availability.
Who it is for
Built for mining & drilling contractors
Our consultancy is designed for operations that depend on drilling productivity day after day.
Mining contractors
Quarry & mining operators
Operations running top-hammer or DTH fleets that want higher penetration rates and lower cost per metre on production drilling.
Drilling contractors
Drilling & blasting contractors
Contractors who live or die by rig availability and drilling speed, and need their machines and crews performing at their best.
Fleet owners
Fleet owners & managers
Teams planning new rig purchases or rationalising a mixed fleet who want independent, vendor-aware technical input.
Our approach
A structured, practical engagement
We keep our process simple and transparent — understand the operation, find the real constraints, and leave you with changes your crews can actually run with.
Start a conversationAssess
We listen to your team, review current drilling practice, rig data and consumable usage to understand where time and metres are being lost.
Diagnose
We pinpoint the real constraints — whether they sit in drilling parameters, rig condition, maintenance habits or parts strategy.
Recommend
We deliver clear, prioritised recommendations and, where useful, hands-on coaching for operators and maintenance crews.
Support
We back the plan with genuine spare parts and maintenance support, and stay reachable as conditions change on site.
