Available to hire
I’m a mining surveyor and mine geology technician with 11+ years of experience supporting open-pit mining operations. I handle mine surveying and geological support across tasks like setting out mining boundaries, conducting stockpile surveys, calculating coal and waste volumes, and keeping mine plans and survey information up to date.
I’m also experienced with GNSS/GPS and Total Station operations, including RTK workflows, and I’ve worked with laser scanning using Mapttek I-Site technology. Alongside technical accuracy, I focus on safety, quality control, and effective documentation—whether mapping geological contacts, sampling rock/coal/soil, or preparing technical reports that support day-to-day mining decisions.
