Dr Gary McArthur

The first 23 years of Gary McArthur’s work experience (1971-1993) were spent as a career mine geologist, with lengthy periods at Mount Isa (Cu), Jabiluka (U-Au), Cleveland (Sn-Cu) and Hellyer (Zn-Pb-Ag-Cu). At Hellyer in Tasmania, he led the post-discovery geological team for 10 years through the drilling delineation stage, feasibility assessment, mine development and ultimately, into full production. This was followed by 5 years as part of Aberfoyle’s senior feasibility team providing geological and resource/reserve input for potential acquisition ventures and advanced exploration projects.
In the field of resource estimation, he has had lengthy experience since 1980 with the geostatistical assessment of mineral resources over a large variety of deposit styles and remains a fluent user of Datamine mining software. His association with metallurgists at Hellyer led to the development of groundbreaking advances in the often-neglected area of ore characterisation. Concurrent research on sulphide microtextures within the Hellyer VHMS deposit led to the award of Ph.D. from the University of Tasmania in 1997.
In 1998, Dr McArthur formed McArthur Ore Deposit Assessments Pty Ltd (MODA) to provide specialised consulting services in the fields of ore microscopy, resource/reserve evaluation, mine geology and data analysis. In the field of mineralogical services, either descriptive mineragraphy or quantitative mineralogy can be provided from sulphide rock samples or ground metallurgical samples. Clients can call upon Dr McArthur’s lengthy experience in all aspects of mine geology for assistance with project feasibility work, due diligence, technical audits, detailed 3-D interpretations, resource/reserve assessments or general mentoring.
