What Byrnecut Offshore Pty Ltd does

Byrnecut Offshore Pty Ltd is a privately held Australian underground contract mining company headquartered in Perth and founded in 1987. The company provides integrated underground mining services to gold and base metals (primarily copper) mine operators, supplying management, labour, equipment, and materials under long-term contracts that often span from feasibility through life-of-mine. Core service lines are Underground Contract Mining, Raise Drilling (using Robbins 61R rigs), Shaft Sinking, and Training and Development supported by immersive-technologies simulators.

Operationally, Byrnecut runs a multimillion-dollar fleet of specialized underground mining equipment (including Sandvik DD421 longhole drill rigs) and deploys thousands of personnel across 13+ countries spanning Oceania, Africa, Europe, Asia, and the Americas. The customer base is concentrated among Tier-1 mining operators, including Newmont (Telfer), Barrick (Kibali), B2Gold (Fekola), and Ivanhoe Mines (Kamoa-Kakula), with several engagements structured as multi-year or life-of-mine contracts.

The revenue model is contract-fee-based: Byrnecut negotiates individual long-term agreements with mining clients for underground development and production work, including raise drilling, boxhole boring, shaft boring, shaft sinking, shotcreting, and feasibility/design studies. Go-to-market is direct enterprise field sales targeting major mining operations globally. The broader Byrnecut Group includes eight wholly-owned subsidiaries (Jetcrete, Raising Australia, Mining Plus, Quattro Project Engineering, Murray Engineering, Fuze, Sano Health, BOAB) that extend the platform into shotcreting, raise drilling, mining consultancy, engineering, technology, and health services.
