+What does NIKHI GROUP do?
Our core business is renting mining drill rigs in-country in Burkina Faso and West Africa. We buy PRD rigs and rent them to exploration, mining and quarry projects. From our Dubai headquarters we also run import, export, re-export and cross-trade operations.
+Which countries do you serve for rig rental?
Burkina Faso, Côte d'Ivoire, Mali, Guinea, Ghana, Togo and Benin. See our markets.
+Which rigs are available now?
The PRD OZ RC reverse-circulation rig (450 m RC capacity, 140 mm holes) is in our fleet and available now. The other PRD rigs on our rig rental page are available on request: we source the right one for your project.
+What is RC (reverse circulation) drilling?
RC drilling uses a dual-wall drill pipe and a down-the-hole hammer: compressed air goes down between the two walls and lifts the rock chips up the inner tube to the surface, where a cyclone and splitter collect a sample for every metre. It is fast and gives low-contamination samples, which is why gold explorers in West Africa use it for exploration and grade control. Read more in RC drilling explained.
+How much does RC drilling cost per metre?
There is no single price: cost per metre depends on depth and hole diameter, ground conditions, total metres, programme length, mobilisation distance and what is included with the rig. Productive hours matter most. See RC drilling cost per metre and what decides the rental price, then send us your programme for a quote.
+Do you manufacture the rigs?
No. The rigs are manufactured by PRD Rigs. NIKHI GROUP buys PRD rigs and rents them in-country, so you get the equipment without the capital outlay.
+How do I get a rig rental quote?
Use the quote form, WhatsApp or phone. Tell us the drilling method, hole diameter, target depth, site location, expected duration and start date — that is what we need to match the rig and price the rental.
+Which drilling methods do you support?
Reverse circulation (RC), DTH and rotary blast hole, quarry and dimension stone, and horizontal dewatering drilling. See drilling services.
+Do you work in French?
Yes. Our team works in English and French, and this website is available in both languages.
