01
RAB / AC
Rotary air blast and air core drilling. Steel or tungsten blades cut through soft ground while cuttings are lifted by compressed air injected into the hole. A fast, low-cost reconnaissance method.

Who we are
A mineral specialisation built on more than ten years of drilling
Elohim Drilling was founded in 2019, continuing the business of BATIMALI, the group’s original water well and foundation drilling company. It was created to specialise in mineral drilling and serve the growing needs of the extractive sector in West Africa.
Building on more than a decade of BATIMALI experience, Elohim represents MMD-Holding’s move into more technical, higher value work in mining: exploration sampling, grade control, water supply and geotechnical investigation.
Our methods
Three drilling techniques, one chain of accountability
From surface reconnaissance to deep coring, we mobilise the method that suits the geological objective and the ground, without multiplying contractors.
02
Reverse circulation (RC)
A destructive method giving accurate metre-by-metre sample recovery. Because the sample returns inside the drill rod, contamination from the walls of the hole is avoided.
- Depth
- up to 350 m
- Use
- Exploration, grade control
03
Diamond core (DD)
A diamond-impregnated annular bit cuts a cylindrical core of solid rock. The most complete geological and structural return, essential to resource work.
- Depth
- up to 1,200 m
- Use
- Resources, structural
Depths are indicative of each method. Contractual depths depend on the programme and on the rig mobilised.
Where we work
Drilling for mining, construction and water
| Field | Service | Methods |
|---|---|---|
| Mineral exploration | Soil and subsurface sampling, prospecting campaigns, delineation drilling | RAB/AC, RC, DD |
| Grade control | Defining ore grade in open pit operations, waste-to-ore boundaries, data for mine planning and blasting | RC |
| Mine infrastructure | Control, dewatering and ventilation holes, and holes for underground services | RC, DD |
| Construction and geotechnical | Surface and subsurface investigation, physical properties of soil and rock for earthworks and foundations | RAB/AC, DD |
| Water and dewatering | Drilling and casing of wells for process plant supply, dewatering and lowering the water table ahead of excavation | Down-the-hole hammer |
Our footprint
A presence built across the sub-region
Côte d’Ivoire
Expanding prospecting operations and commercial coordination for Ivorian programmes.
Mali
Strategic partnership with Sud Mining on the Minkoro and Linguekoro properties, in collaboration with Desert Gold.
Guinea
Work carried out through the MMD-Holding group on various gold projects.
Burkina Faso
Technical assistance and prospecting in sensitive areas.
Equipment and crews
Complete crews, self-sufficient on site
- Integrated shift crew — site supervisor, driller, offsiders, mechanics, electrician, welder and HSE officer.
- Logistical self-sufficiency — service trucks, light vehicles, air compression and water supply integrated into the drilling spread.
- On-site maintenance — mechanics and welders embedded in the shift to limit production downtime.
- Geological supervision — geologists, surveyors and safety technicians mobilised according to the programme.
Rig types our crews are experienced on
- Schramm 600
- EDM 2000
- UDR 1000
- UDR 1200
- Exploroc E100
- Rock L8
- KWL 1600
- Drill Star 5000
- LF90
- LF160
- GT450
Experience gained by our drillers and mechanics over their careers. The rigs actually mobilised on a contract are specified in each proposal.
Safety and compliance
HSE, sample traceability and vendor pre-qualification
Working for an industrial mine demands documentary discipline as much as operational discipline. We organise for both.
HSE standards
An HSE officer embedded in every shift crew, personal protective equipment, pre-shift briefings and procedures aligned with the requirements of international mining clients.
Sample traceability
Metre-by-metre bagging, sequential numbering, chip trays for control, insertion of quality control samples to the client’s protocol and handover to a partner laboratory.
Pre-qualification pack
Corporate, tax and social documentation, insurance certificates, HSE plan, equipment data sheets and crew CVs provided on request for know your contractor checks.
The context
The market we operate in
West Africa is one of the most active gold provinces in the world. The figures below come from official sources, with the reference year stated.
| Country | Gold production | Year and source |
|---|---|---|
| Ghana | 130 tonnes gold content, estimated | 2024, USGS Mineral Commodity Summaries 2025 |
| Ghana, national figure | 5,077,425 ounces, of which 2,200,143 from small-scale mining | 2024, Minerals Commission of Ghana |
| Mali | 70 tonnes gold content, estimated | 2024, USGS Mineral Commodity Summaries 2025 |
| Burkina Faso | 60 tonnes gold content, estimated | 2024, USGS Mineral Commodity Summaries 2025 |
| Côte d’Ivoire | 41.857 tonnes achieved; 47 tonnes forecast | 2021 and 2024 forecast, Ivorian Ministry of Mines |
| World production | 3,300 tonnes, estimated | 2024, USGS Mineral Commodity Summaries 2025 |
USGS estimates and national statistics do not use the same scope: USGS reports gold content, while administrations publish declared production, sometimes excluding small-scale mining. Both are shown as published.
