Drillex OÜ

What Drillex OÜ does

Drillex International (legal entity Drillex OÜ) is a privately held Bulgarian-headquartered drilling services contractor founded in 1995, providing exploration and production drilling to the global mining and mineral exploration industry. The company operates four service lines — Diamond Drilling (wireline core extraction with diamond-bit tooling), Reverse Circulation Drilling (pneumatic hammer drilling to depths up to 500 metres), Grade Control Drilling (real-time, RC-based ore-body definition to 300 metres for open-pit mining optimization), and Geo-technical Drilling (engineer-supervised site analysis for construction projects) — delivered through a fleet of approximately eight drilling rigs (GEMEX, CORTECH, BARKOM, ALTON) supported by DENAIR/Atlas Copco/Sullair/Doosan compressors, ARC 1310 boosters, Solids Removal Units, track carriers, and vehicles.

The business model is a hybrid of professional-services project contracts (multi-year, quote-based, scope-defined) and, as of February 2025, a usage-based equipment rental stream monetizing the existing fleet. Go-to-market is consultative enterprise field sales, with direct engagement of mining majors, mid-tier producers, and junior explorers across a Balkans-plus-Oceania footprint anchored by offices in Kostinbrod (Sofia, Bulgaria), Bor (Serbia), Vareš (Bosnia and Herzegovina), and Australia. Disclosed enterprise customers include Tethyan Resources, Mundoro Capital, Medgold Resources, Dundee Precious Metals (Krumovgrad and Chelopech operations), Boart Longyear, and Avala Resources. The company holds TUV Austria ISO 9001/14001/45001 certifications, markets a "zero harm" safety culture, and is led by General Manager Richard (Richie) Rose. No funding rounds, no headcount disclosure, and no revenue figures are available in the source material, limiting financial visibility.

Products and services

• Diamond Drilling Exploration diamond drilling service that extracts solid core samples from depth for geological examination, using industrial diamond bits set in a soft metallic matrix mounted on core barrels attached to drilling rigs. Aimed at mining and mineral exploration companies seeking high-quality core presentation and orientation for ore deposit verification.
• Reverse Circulation (RC) Drilling Pneumatic drilling method using a reciprocating piston hammer driving a tungsten-steel drill bit, capable of reaching depths up to 500 metres with dry rock chip samples via a differential pressure air lift system. Designed for mining and mineral exploration companies needing fast and effective exploration drilling.
• Grade Control Drilling RC-grade control drilling service for open pit mining operations that defines ore grades and blocks to optimize ore extraction, mine planning, and blasting patterns, with depth capacities up to 300 metres and real-time grade guidance on desired depth, angle, and alignments. Aimed at mining operators requiring productivity and sample quality.
• Geo-technical Drilling Geotechnical drilling service performed under engineer supervision for site analysis to establish ground suitability for construction of buildings, tunnels, highways, and dams, evaluating rock and soil conditions and underground water levels. Targeted at construction and infrastructure companies requiring site safety assessment.
