Gold and Mining Services



McNeill have a strong history within gold, coal and mineral exploration throughout the South Island.

The McNeill fleet is comprised mostly of highly mobile, wheeled units making for easy, cost-effective site access.  Our equipment is specifically designed for New Zealand’s harsh alluvial gravels effectively achieving a wide range of testing and sampling options including; air core open hole, diamond core and RC sampling and sonic geotechnical sampling.

Teamed up with water bore drilling, drainage and dewatering rigs and piling and anchoring capabilities, we have every site and mining situation covered.

Combine great equipment, expert operators, established procedures and good relationships with local bodies - it’s no wonder McNeill have been chosen for the variable conditions of Southern alluvial operations.
