Biography:

Josh is undertaking a Ph.D at the Department of Earth Science, Durham University, within the Volcanology Research Group. His Ph.D. focusses upon the migration and infiltration of evolved magmatic liquids, and volatile and trace element enrichment, within the Klokken syenite intrusion. Klokken is located within the Gardar Igneous Province of South Greenland. Magmas within the province are typically enriched in LILE, HFSE and F and host a number of Tier 1 REE-Nb-Ta-Zr ± U deposits (e.g. Kvanefjeld, Kringlerne and Motzfeldt). Better characterisation of the migration of late-stage, evolved melts such as those identified at Klokken has wider implications for our understanding of ore forming processes in magmatic systems.

A graduate of Cardiff University (UK), Josh holds a First Class Masters degree (MESci (Hons)) in Exploration and Resource Geology, with a thesis on unconventional diamond host rocks. His thesis was awarded the “SRK Consulting Prize” at the 36th Mineral Deposits Studies Group (MDSG) Conference. He is an elected Fellow of the Geological Society of London and a was recently awarded a Graduate Fellowship of the Society of Economic Geologists and a Pam Edgar Fellowship of the Institute of Materials, Minerals and Mining (IOM3).

He holds expertise in the exploration and targeting of gold, base and specialists metals, and diamonds in Proterozoic and Archaean terranes, including seven years of experience throughout Greenland. Josh was employed by the partially state owned national mineral exploration company, NunaMinerals A/S (“NUNA”) for six years, most recently as the company’s Chief Geologist, managing an annual exploration budget of £1.5-2.2 million. During his time as Chief Geologist he developed the company’s flagship Vagar gold project located within the Paleoproterozoic Nanortalik Gold Belt of South Greenland, resulting in the most significant gold discovery in Greenland to date (e.g. 11 metres at 80.2 g/t gold). He was also responsible for a Joint Exploration Agreement between NUNA and Korean state owned, Korea Resources Corporation (KORES) for a REE-Nb project in West Greenland, an Option and Joint Venture Agreement between NUNA and Greenland Rare Earth Projects Ltd for a REE-Nb-Ta-Zr project in South East Greenland, and an Alliance Agreement between NUNA and Rio Tinto. Josh was Director of Nanoq Resources Ltd during which time he managed gold exploration within the Archaean Tartoq greenstone belt, South West Greenland. He has also managed brown field exploration projects on behalf of Angel Mining PLC at Nalunaq gold mine (Greenland’s first gold mine) and more recently consulted to to SRK Exploration Services (UK) Ltd and Arctic Resources Capital (and its subsidiaries).

Josh has been a guest speaker and expert panelist at the British Government’s Department of Trade and Industry, advising policy makers and UK businesses on foreign direct investment in the Arctic’s emerging exploration and mining industry. Recently he was an expert panelist on two Mineral Assessment Workshops co-hosted by the Greenland Government’s Ministry of Mineral Resources and the Geological Survey of Denmark and Greenland, on orogenic gold and titanium-vanadium deposits in Greenland. Josh has also lectured on a Masters-level module in Metallogeny at the University of St Andrews where he was a Tutor in Earth Sciences.

Josh is a member of the North Atlantic Craton Conference organising committee – held in St Andrews in 2014 and Edinburgh in 2016. The NAC conference has successfully promoted and cemented mutual co-operation internationally between academia, industry and policy makers regarding mineral deposits associated with the Archaean North Atlantic Craton and adjoining Proterozoic Mobile Belts and has the wider aim of coagulating exploration efforts across Canada, Greenland and Fennoscandina. Owing to its popularity it has become a bi-annual meeting and will be held again in 2018.

Josh is a Member of the Institute of Materials, Minerals and Mining; Member of the Mineralogical Society of Great Britain and Ireland; and a Member of the Prospectors and Developers Association of Canada.
