Meet our small team that achieve lots.
Undoubtedly a great mob behind the successful Perth Gem and Mineral Show
Peter Willems
President
Peter grew up in Hobart where he showed interest in minerals from a young age, plaguing mum’s washing machine. He studied a BSc, majoring in Geology at the University of Tasmania. In 2014, he was awarded the Christopher Holmes Scholarship Award for outstanding achievement in Mineralogy. Through university, Peter ran a hobby business as a mineral dealer, sourcing minerals from across the world as well as regular field collecting.
As a graduate, Peter worked at Regis Resources in open cut mining, across four contrasting orogenic gold deposits, and in exploration across nine deposits and prospects. Peter has worked in underground mining at Sandfire Resources since September 2017, including secondment as a Geotechnical Engineer. He used his combined knowledge from underground Geology and Geotechnical activities to build a structural model for DeGrussa, which has become an integral entity for the Technical Services team.
Peter has a passion for mineralogy and is both president of MinSocWA and of PGMS Sub-Committee. Evidently, he has become the head of the Perth Gem Mineral Show & team. He also represents one third of The Outback Gem Co., sourcing and selling mineral specimens from around Australia.
Kylie Matonia
Secretary (and lots more)
Kylie Matonia is a born and bred South Australian, who swapped out the wineries and rolling hills of Adelaide for the red dirt of the Western Australian Outback. She has worked in exploration in SA and Indonesia, as well as mining operations in WA. Partial to a nice specimen or two, and passionate about education, sharing geological wonder and bringing people together. Extraordinarily committed to make the Perth Gem and Mineral Show the event that Western Australia deserves, Kylie has invested countless hours in getting things done for the team.
Kylie used her public relations skills to bring numerous geoscience actors on the table, gathering interest of the industry, and thus securing the future of the show. Her dedication in the mineral world is such that Kylie has now joined the Mineralogical Society of Western Australia, strengthening the links between the two entities.
Nicolas Hébert
Co-Founder / Webmaster
Nicolas is a geologist at Dalgaranga Gold mine for Gascoyne Resources. After graduating from his M.Sc of Geological engineering in France, he prospected several gem-producing areas across South-East Asia.
Nicolas fossicked many French historical mineral occurrences from the Vosges Mountains to the Alps and Massif Central looking for smoky quartz, fluorite, along with minor Cu-Bi-Mo-As-Sb mineralisation. His more recent trips focused on marble-hosted paragenesis, with a strong emphasis on Luc Yen (Vietnam) and Mogok (Myanmar) incredible mineral diversity.
Soon after emigrating to WA, Nicolas got involved with MinSocWA by offering lectures on the ruby/spinel assemblage found in these regions, and another talk for the Australasian seminar on the color of blue spinels. He since has done a few others about faden quartzes for PGMS 2021 and discussed the orange fluorescent minerals from Mogok at Tucson Symposium 2022. The idea of bringing a show of similar stature as the one in Sainte-Marie-Aux-Mines to Perth seemed obvious. Quite naturally, Nick joined the group of enthusiastic young members as the 2021 PGMS treasurer and social content manager. His role in the team is now is solely focused on the website development.
Mitchell Elphick
Social Media Manager
Mitch is one of the general committee team members organising the inaugural Perth Gem and Mineral Show.
A WA local, he finished his B.Sc in Geology at Curtin University in 2015 and has been exploring, mining and rummaging around the bush causing mischief ever since.
He is currently working for Fortescue Metals Group as a Geologist in the Iron Ore division, and has previously worked for several years exploring the wilds of Western Australia for Gold, Base Metal and Lithium deposits.
With a keen interest in gemstones from a young age he naturally gravitated towards lapidary, mineral collecting and hoarding as many rocks as humanly possible.
In 2019 he co-founded @theoutbackgemco with the goal of artisanal mining and dealing in Australian minerals, this ongoing enterprise with co-founders @case.y__ and @rock__licker has taken them to some of the most iconic mineral occurrences in WA.
Mitch is a keen geologist, an advocate for mineral heritage and very excited to be a part of The Perth Gem and Mineral Show.

Casey Elphick
Co-Founder
Casey is a WA local, growing up on the Darling Scarp where a childhood of rock-hopping quickly evolved into a passion for rock hunting, climbing, trading and studying.
Casey graduated from Curtin University in 2018, with a B.Sc in both Geology and Environmental Biology. In 2019 she co-founded @theoutbackgemco with Pete and Mitch whilst working for Fortescue Metals Group as a Geologist. She has since entered the world of Hydrogeology, where she can be found chasing groundwater across the Pilbara.
Casey has always been passionate about science communication, and is excited to help establish the PGMS as a space for geoscience enthusiasts to collaborate, educate and inspire.
John Mill
Treasurer 2022
John is a good guy, with lots of experience, joining the 2022 team.
After managing MinSocWA’s as treasurer for years, John was naturally to be involved in progressing Perth towards having a top class gem and mineral show.
