Mining, Quarrying & Gas

Monteath & Powys have a great deal of experience undertaking work for mining, quarrying and gas projects throughout New South Wales.  With offices based in Newcastle, Muswellbrook, Gunnedah and Sydney, we are well placed to service any project in the Hunter Valley, Central West, North West and Illawarra areas of the state.

Our Surveyors have many years of experience in both underground and opencut operations for coal, metalliferous, coal seam gas and pipeline projects. We can carry out surveys for any purpose to meet contractual conditions or legislative needs, including meeting the requirements set out in the Survey and Drafting Directions for Mining Surveyors.
