As Australia’s premier drilling contractors with an innovative fleet of drill rigs, Numac provides drilling services across New South Wales and has an outstanding track record of managing all quality, safety and environmental requirements to the highest industry standards. We work with clients across a diverse variety of industries to deliver drilling solutions for projects such as:

Mineral exploration drilling programs

Our highly-trained operators have taken our sonic drill rigs down to over 100m in unconsolidated formations to provide full mineral sample recoveries from 0-100m. Projects include mineral exploration and large diameter bulk sampling for major mining companies.

Groundwater sampling, mapping and profiling

Our direct-push drill rigs are fitted with Geoprobe® SP16 samplers to collect groundwater samples from unconsolidated materials at depths ranging from near ground surface to over 30m. We’ve worked on a range of projects including hydrogeochemical research and groundwater resource characterisation.

Municipal water production bore drilling and installation

We work on water production projects in varying capacities, including as principal contractor on large-scale municipal water well construction projects. Clients include state-owned drinking water and wastewater companies and privately-operated water treatment plants.
