Sonic Drilling

Designed for efficiency and precision, sonic drilling employs high-frequency, resonant energy generated within a sonic head to propel a core barrel or casing into subsurface formations via high frequency oscillation.

Widely used in geotechnical, environmental and groundwater investigations sonic drilling stands out for its ability to produce high-quality sample recovery in diverse and extremely challenging geological conditions.
Unconsolidated and hard formations are easily overcome, without the use of drilling fluids and additives, whilst providing continuous core sample and seamless casing advancement via a cleaner drilling solution.

At Hagstrom, we utilise state-of-the-art sonic drilling technology for rapid penetration through challenging geology, providing safe, efficient and on-time drilling solutions for any project.

Our sonic drilling expertise covers a range of applications, from helping to determine mining and processing methods, to resource mine planning and control.

We can assist with:

• Geotechnical assessment of Tailing Storage Facilities and embankments
• Producing accurate-to-depth samples in extremely challenging geology, such as paleochannel, with 100% recovery
• Identification of groundwater inclusive of monitoring well, pumping well and production bore installation.
• Determining ore and residual resource values in tailings piles
• Mapping hard formations within ore bodies and clay content (slimes)
• Sonic coring up to 10” sample diameter
• Pre-collaring overburden prior to advancement of Diamond Drilling “tails” during exploration drilling

Our project experience covers a range of commodities including iron ore, cobalt, nickel, silver, lithium, phosphates, gold (placer), manganese and coal.
