Biography
Kathy Ehrig completed her Ph.D. degree in geology at the University of California-Berkeley in 1991. She left San Francisco in 1992 to commence working on the genesis of the Olympic Dam deposit in Australia and to provide mineralogical support for the Olympic Dam processing plant. In 2006, she moved to Adelaide to lead the development of the Olympic Dam geometallurgy program. However, she has remained focused on using mineralogy to solve processing issues, unraveling the complex geologic history of the Olympic Dam deposit, and using deposit-scale geologic/mineralogical insights as inputs into discovering new iron oxide copper-gold deposits.
She has cosupervised 14 Ph.D. students and nine postgraduate researchers working on Olympic Dam based projects. She has shared the geologic/geometallurgical knowledge gained from Olympic Dam and surrounding prospects by authoring or co-authoring more than 125 published papers and delivering mor than 65 presentations.
She received the 2017 Professional Excellence Award from the Australasian Institute of Mining and Metallurgy (AusIMM) and a degree of Doctor of Science honoris causa from Flinders University in recognition of her contribution to the geologic and geometallurgical understanding of the Olympic Dam deposit. Other awards include the Geological Society of Australia Bruce Webb Medal (2018), the Society of Economic Geologists Silver Medal (2020), the Australian Geoscience Council Roy Woodall Medal (2020), and the Australian Academy of Sciences Haddon Forrester King Medal (2022). She is a chartered professional of the AusIMM.
