Brown Bros (NZ) Ltd are held in high esteem within the mining and quarry exploration industry.
Our rigs are purchased new from respected overseas manufacturers and are chosen for their rugged construction, high capacity and lower down times, as required in the difficult and abrasive environments.
Mining and quarry exploration drilling is undertaken to estimate the resource volume, determine the amount of overburden, or to direct mining operations to the ore body. Geological resources can include sand, pumice, china clay, sulphur, coal, gold and other materials.
All terrain equipment

Mineral and quarry drilling methods include:
