A member of the department’s Volcanology & Magmatism Research Group, Josh’s Ph.D focusses upon the formation of igneous layering, the migration and infiltration of evolved magmatic liquids, the rheology of crystal mushes, and volatile and trace element variations within the Klokken syenite intrusion. Klokken is located within the Mesoproterozoic Gardar Igneous Province of South Greenland. Magmas within the province are typically enriched in LILE, HFSE and F and a number of intrusions host Tier 1 REE-Nb-Ta-Zr ± U deposits (e.g. Kvanefjeld, Kringlerne and Motzfeldt).
Melt infiltration through, and interaction with, a crystal mush is a poorly understood part of the magmatic system, yet has a fundamental bearing on volcanic, magmatic and ore-forming processes at a range of scales. The Klokken intrusion provides a remarkable natural laboratory in which to study melt-mush interaction processes at a micro- to macro-scale. Improved characterisation of reactive liquid flow has wider implications for our understanding of ore forming processes in magmatic environments for a range of commodities (including Cr, PGE, Au, REE, Nb, Ta, Zr and U).
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 within the North Atlantic Craton.
Josh has significant expertise in the exploration and targeting of gold, base and specialists metals, and diamonds in Proterozoic and Archaean terranes in the Arctic and Africa, including seven years of experience throughout Greenland. He was employed by Greenland's partially state owned national mineral exploration company, NASDAQ-listed NunaMinerals A/S (“NUNA”) for six years, most recently as the company’s Chief Geologist, managing an annual exploration budget of up to £2.2 million GBP.
As Chief Geologist at NUNA he was responsible for the most significant gold discovery in Greenland to date (e.g. 11 metres at 80.2 g/t gold) at the company’s Vagar gold project. Vagar is located within the Palaeoproterozoic Nanortalik Gold Belt of South Greenland that also hosts the Nalunaq gold deposit (Greenland’s first gold mine which produced 10.65 tonnes gold between 2004 – 2013 at an average grade of 15 g/t). Josh was also responsible for a Joint Exploration Agreement between NUNA and the 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 Mining & Exploration Ltd.
Josh was Founder and Managing Director of Nanoq Resources Ltd during which time he developed the Tartoq gold project (Archaean greenstone-hosted gold) in SW Greenland, which was sold to AEX Gold Inc. (formally Alopex Gold Inc.; CVE:AEX) in 2016. He has also managed brown field exploration projects on behalf of Angel Mining PLC at Nalunaq gold mine and provided consultancy to SRK Exploration Services (UK) Ltd and Arctic Resources Capital on gold and graphite exploration projects in Greenland.
Josh was recently a consultant geologist for Mkango Resources (LSE:MKA; TSX-V:MKA) on their 10,900 meter diamond drilling program at the Songwe Hill carbonatite-hosted REE project in southern Malawi (and surface exploration of the Nkalonje carbonatite). He is currently External Senior Consultant with Helvetica Exploration Services GmbH, Switzerland.
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 at several 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, magmatic titanium-vanadium and uranium deposits in Greenland.
Josh is currently a postgraduate demonstrator on the modules "Volcanology and Magmatism" and "Igneous and Metamorphic Geochemistry and Petrology". He has also lectured on a Masters-level module in Metallogeny at the University of St Andrews where he was a Tutor in Earth Sciences (2014 - 2015), and has co-supervised BSc and MGeol level research projects with Prof. Adrian Finch, on mineralisation associated with alkaline magmatism.
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, learned societies 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.
