Compare diamond core drilling and conventional rock drilling for mineral sampling. Explore sample quality, geological detail, speed, costs, ground conditions, and rig selection to determine which method best supports your exploration objectives and how CORTECH can help configure a suitable solution.

Who makes core drilling rigs in India? Compare PRD Rigs, Kores Engineering, and KLR, plus Epiroc and CORTECH as international options. Learn how to assess NQ/HQ/PQ depth ratings, wireline equipment, service support, and total cost before choosing a surface diamond-core rig.

Compare surface and underground core drills for geological exploration. Learn how collar location, borehole geometry, wireline recovery, site safety, and full-program cost shape the right rig choice—and what to send a manufacturer before requesting a quote.

This article compares small-scale prospecting and large-scale mine development from an operational, and equipment strategy perspective. It explains how to scale a drilling fleet, when to add rigs, and how CORTECH's fully hydraulic wireline diamond drill solutions can support both early exploration and mine development.

This article examines how diesel-hydraulic and electric-hydraulic rigs power modern core surface drilling projects in 2026. It compares fuel and electricity cost structures, operator experience, and site scenarios, then outlines a practical framework and monitoring approach to help drilling fleets match rig architectures to specific project conditions and achieve more predictable cost per meter.

Learn the real engineering differences between surface drilling rigs and underground drilling rigs. Compare structure, hydraulics, safety, and cost‑per‑meter, and see how CORTECH’s fully hydraulic wireline core rigs support both exploration and in‑mine drilling programs.
