Tom Kendall is a Consulting Engineer with 25 years’ experience in mining, mineral dressing and heavy industry. He has specialist expertise in materials handling, underground mine infrastructure, heap leach and CIP technology. Tom gained his initial nine years operations experience in underground mines, mineral beneficiation plants and quarries with WMC Resources and CSR Readymix, and is the holder of a WA Quarry Manager’s Certificate of Competency.
Tom has fifteen years experience as a consulting engineer in Kalgoorlie, culminating in the merger of Kendall Engineers with Sinclair Knight Merz in 1997. He left Sinclair Knight Merz in 1999 to take control of Holtfreters, a general engineering works based in Northam WA, which has been servicing WA industry for 50 years. The Holtfreters project office in Perth was established as a result of Tom’s joining Holtfreters and is undertaking engineering design and consulting work as well as smaller turnkey design and construct projects.
Tom has undertaken a wide variety of exciting projects in his career. Some involved full project design and management of mine infrastructure and treatment plants such as Bellevue and Higginsville in the WA goldfields. Others have been ground-breaking projects such as using mechanical ore sorters to separate nickel ore from gangue and the design of a high pressure pumping system to de-water the Golden Mile beneath the Kalgoorlie Super Pit in a single 700 metre vertical lift through a suspended pipe.
With most of his experience gained in close proximity to the operations of the eastern goldfields of WA, Tom has a ready appreciation of the potential impact of design philosophy on operating costs and life cycle costs.
