Numac recently completed a mineral exploration drilling program with a sonic rig in unconsolidated formations for Nickel Laterite.

One of the highlights of 2017 was being involved in the Sydney Metro Geotechnical investigation in Sydney Harbour. Numac was presented with an opportunity to use one of our Sonic drill rigs from a overwater in close proximity to the Harbour Bridge.

Numac are very proud to be awarded 3rd party accreditation from Best Practice Certification for our Safety (AS/NZS 4801), Quality (ISO 9001) and Environmental (ISO14001) 

As Australia's leading provider of High Resolution Site Characterisation (HRSC), Numac welcomes back David Heicher from Dakota Technologies for his keynote presentation at Cleanup 2017:

".....look for a cost-effective method for characterising shallow groundwater resources in remote Northern Australia"

Numac Drilling Services Australia was awarded a public tender by Hunter Water to manage and undertake the drilling and installation of 15 municipal water production bores within the existing use regional aquifer.

Using tracers to Investigate aquifer recharge. A wide a range of tools wre employed to gather data including monitoring wells, the Hydraulic Profiling Tool (HPT), Geoprobe push tube soil sampling and the SP16 groundwater sampler in this investigation.

Early 2016 saw 2 Geoprobe machines running double shift for a large scale environmental assessment. The investigation included a large Membrane Interface Probe (MIP) investigation which we believe was a first for Singapore. 

Sonic Drilling is taking off in Australia and is quickly becoming the preferred tool in both Environmental and Geotechnical site investigations. After a couple of years of use this is the lowdown on where we see the value.
