John was born in Western Australia, growing up in the small mining town of Leonora and then later in the Perth Hills. Both John’s parents are University of Western Australia geology graduates and his first three years out of school he took on formative work with his father as an exploration field assistant throughout WA. In 2014, he began an undergraduate degree in geology and finance at UWA which included a semester abroad at HEC Montreal, Canada. Throughout his undergraduate studies John applied himself in several geology vacation programs undertaking exploration activities associated with Sandfire Resources’ DeGrussa Cu-Au Mine, Evolution Mining’s Mungari Operations in the Kundana Au camp, and Pilbara Minerals’ Pilgangoora Li-Ta Project. During his vacation program at the Pilgangoora Li-Ta Project John first gained exposure to rare-metal pegmatites and for him what is an enormity of questions that remain to be answered about the genesis and exploration criteria of this exciting and emerging economic mineral system. John went on to complete an honours year for geology in 2018, and with the supervision of Tony Kemp and support of Pilbara Minerals, he produced a first class thesis entitled “Evidence for multi-stage phase evolution and metallogenesis in the Pilgangoora Li-Ta pegmatite district, East Pilbara Terrane, Western Australia”. John enjoyed 14 months of full-time employment as an exploration geologist following on from his honours year.

John commences a PhD study in March 2020 at UWA and the Centre for Exploration Targeting under the supervision of Associate Professor Tony Kemp and Professor Steffen Hagemann, and with the support of UWA’s Robert and Maude Gledden Postgraduate Research Scholarship and the Minerals Research Institute of Western Australia. His research is once again concentrated on rare-metal pegmatite genesis, this time at the scale of the northern Pilbara Craton where he aims to employ field mapping, geochronology, geochemistry and isotopic studies to elucidate the petrogenesis of the late Mesoarchaean Split Rock Supersuite granites and their associated pegmatite fields. The project will specifically focus on the geological processes linking granites and pegmatites, the sourcing of rare-metals (Be, Cs, Li, Nb, Sn, Ta), and the regional geodynamic controls and local structural controls that lead to emplacement of this important mineral system.
