Exploration drilling demands equipment that is productive, reliable and adaptable, often operating far from established infrastructure and in some of the world's most challenging environments. As programmes progress from early-stage reconnaissance through to resource definition, drill rigs must often accommodate changing drilling methods, deeper holes, varying ground conditions and environments, all while maintaining safety and efficiency.

Exploration Drill Masters (EDM) is an original equipment manufacturer (OEM) dedicated exclusively to exploration equipment. The company designs and manufactures a comprehensive range of diamond, reverse circulation (RC) and multipurpose (MP) exploration rigs, along with horizontal minesite dewatering rigs and a broad portfolio of hands-free rod handling solutions for any drilling method. This focused approach enables EDM to support exploration contractors and mining companies with equipment engineered specifically for the realities of mineral exploration projects.

Built in the Andes: experience shaped by demanding conditions

Established in Chile in 2008, EDM developed and proved its early equipment in the high-altitude, extreme cold and geologically complex conditions of the Andes Mountains. Operating in this environment placed immediate demands on rig durability, performance, and serviceability — challenges that helped define EDM's design philosophy.

Delivering consistent performance at altitude and in remote terrain allowed EDM to build a strong reputation for productive, efficient exploration rigs. That reputation extended beyond South America, supporting steady international growth and positioning EDM as a recognised exploration OEM across multiple regions. Today, the company enjoys significant global reach, with Africa and the Americas representing its largest and most active markets.

A complete exploration rig portfolio

Exploration programmes are rarely uniform. Contractors may require high-capacity diamond rigs for deep coring, efficient RC rigs for rapid sample generation, or flexible multipurpose machines that can adapt as project requirements evolve. EDM's portfolio reflects this operational reality.

The company manufactures dedicated diamond and RC rigs, as well as multipurpose machines that deliver flexibility without compromising productivity. In addition, EDM offers a range of horizontal mine-site dewatering rigs. Equipment can be supplied in configurations ranging from simple hydraulic control systems to fully electric-over-hydraulic (EoH) rigs with PLC and touchscreen control interfaces, depending on project requirements.

Across the range, emphasis is placed on usability, robust construction, practical machine layouts and straightforward service access. Components are selected for durability in harsh environments, while designs prioritise ease of maintenance - a critical factor in sustaining uptime at remote exploration sites.

Advancing safety through hands-free rod handling

Reducing manual handling and improving operator safety remains a key focus across the drilling industry. EDM has made sustained investment in hands-free rod handling systems designed to reduce operator exposure, fatigue and repetitive manual tasks.

EDM's rod handling solutions include diamond pipe handlers, RC pipe handlers, large diameter water well pipe/casing handlers and horizontal pipe presenters, that can be integrated onto multiple different machines and maximise safety without compromising productivity.

Growth across AME Africa and the Middle East

EDM's expanding presence across Africa and the Middle East reflects the suitability of its equipment for demanding exploration environments and remote locations. In these regions, where drill rigs must operate reliably in high temperatures, abrasive dust conditions and in locations where logistics and technical support can be limited.

EDM's manufacturing approach for these regions prioritises robustness, simplicity and serviceability, supporting sustained performance and productivity over long drilling campaigns. Combined with practical on-site commissioning, training and technical support, this focus has enabled the company to establish long-term relationships with exploration contractors and mining companies operating across diverse jurisdictions.

Collaboration as a manufacturing philosophy

A defining aspect of EDM's approach as an OEM is its emphasis on collaboration. Exploration projects frequently present unique technical and logistical requirements, including drilling depths and hole diameters, site conditions, transport and access constraints, varying safety requirements, and local regulatory frameworks.

EDM works closely with clients to configure equipment that aligns with specific project objectives. This may include adapting rig layouts, integrating custom safety systems or tailoring rod-handling solutions. By focusing on how equipment will be used in the field, EDM ensures its rigs deliver practical value throughout the life of an exploration programme.

Looking ahead

As exploration continues to push into more remote and technically demanding regions, with improved safety and increasing levels of automation, the expectations placed on drilling equipment manufacturers continue to rise. OEMs must deliver safer systems, higher productivity and greater adaptability, while maintaining reliability under sustained use.

From its origins in Chile's Andes to a global footprint spanning almost every continent, EDM has built its reputation on engineering and manufacturing exploration drilling equipment capable of unmatched performance and safety in the most demanding environments.
