Gold at Yukon Geoscience Forum

Rob Chapman presented a talk entitled ‘Fingerprinting of ore deposit styles in central Yukon using detrital gold mineralogy’  ‘to the Yukon Geoscience Forum, in Whitehorse Yukon on 20th November. The forum was attended by approximately 400 delegates from industry, Government Geological surveys and Canadian Universities. In addition Rob gave a talk entitled ‘Gold Grains are really complicated things’ to the Yukon Placer Miner’s forum on Nov 19th. The Forum is an annual event organised by the Yukon Geological Survey and addresses various aspect of geology, engineering and licensing relevant to the buoyant placer mining industry in Yukon.

NERC DTP PhD projects

New ores-related DTP PhD projects are now open for applications, deadline 8 January. The three projects are looking at: Regional-scale controls of gold using structural modelling and geochemical approaches; relationships between gold geochemistry and microstructure; and experimental approach to gold precipitation. Please get in touch if you have any questions.

Tiny gold grains could hold key to copper deposit 'DNA'

The outcomes of a study by Rob Chapman and MSc student Tom Mileham funded by Geoscience BC (a British Columbia government funded agency) were the subject of a dedicated press release last week. The study identified a generic compositional signature in gold grains formed in alkalic copper-gold porphyries in British Columbia.

Three new MGeol research projects start in 2017

The final year of the ‘Mgeol’ 4 year degree program at Leeds now contains a research project which corresponds to just under half the year’s workload. This year three students have elected to study ore geology related topics.

Lauren Tuffield is investigating specific mineral systems which form complex inclusions in gold grains from specific localities in the Yukon. These mineral assemblages typically contain elements such as Cu, Ag, Pb, Bi, S, Te, and Se. Lauren will investigate mineral stability fields to constrain the conditions of formation of the gold particle host. In addition she will use trace element maps generated through TOF LA-ICP-MS to investigate how such inclusions form.

Tom Matthews is addressing on of the UK’s geological mysteries; the unknown source of the placer gold exploited during the Sutherland Gold rush of 1869. Tom will be looking at the mineralogy and trace element compositions of gold grains from throughout the Sutherland goldfield and relating these to somewhat rare specimens of float to identify plausible geological models for the genesis of the gold.

Jakub Skrzynecki is working with the USGS, focussing on gold bearing mineralization in Alaska. Jakub is characterizing the mineralogy of hypogene and placer gold from several occurrences in the vicinity of the Pogo Mine. The aim is to identify whether gold derived from intrusion- related mineralization exhibits a characteristic signature that may be applied in the context of exploration.

PhDs welcome

A warm welcome to our three new PhD students. Hugh will be looking at the evolution of porphyry-epithermal gold systems using trace element mobility and concentration; Georgian's project will be about physio-chemical controls on gold-bearing veins in the British and Irish Caledonides; and James will research into structural controls of orogenic gold in Northern Ireland and implications for orogenic gold genetic models. We are all delighted to have them in the team.

Rob in Alaska

Rob Chapman was invited to contribute to fieldwork in Alaska which forms part of a USGS project investigating gold metallogeny in the Tintina gold belt. The fieldwork was also supported by the Yukon-Alaskan Metallogeny project based at the Minerals Deposit Research unit at UBC, Vancouver. The fieldwork involved characterization of mineralization in various in situ occurrences in the environs of the Pogo mine, and collection of detrital gold to evaluate its potential as a pathfinder.

Rob gets around!

Dr Rob Chapman has been appointed as External Examiner at Camborne School of Mines for the Mining Geology MSc program and the new Mineral Exploration MSc programme. He has also been invited by the National Science and Engineering Research council of Canada (NSERC) to be a panel member for the renewal of the ‘NSERC-Agnico-Eagle Industrial Research Chair in Mineral Exploration” at Laval University, Quebec.

Welcome to our new students

We would like to welcome three new PhD students: 

Hugh Graham: Trace element mobility and concentration in Cu-Au magmatic hydrothermal systems (Supervised by Dan Morgan, David Banks, Rob Chapman, Steven Stackhouse)

Georgian Manuc: Mineralized veins: how did they get there? A combined physiochemical approach to vein formation. (Supervised by Taija Torvela, Rob Chapman)

Also, a warm welcome to James Ball, recipient of a 2-year Undergraduate Research & Leadership Scholarship. James will be contributing to the Caledonian gold mineralization studies.

Leeds at AMEBC Roundup 2017

OMG had again a strong presence in Vancouver at the Association of Mineral Exploration British Columbia Roundup in January 2017. Rob Chapman, Carl Spence-Jones, Taija Torvela, and seven MGeol students spent a fruitful few days at the talks and posters, interacting with industry, and looking at rocks. OMG presented three posters:

Spence-Jones C, Chapman R, Banks DA: Evaluation of trace elements in gold by LA-ICP-MS: preliminary results of placer lode studies in British Columbia.

Chapman R, Banks DA, Spence-Jones C, Borovinskaya O, Grimshaw M: Trace Element Quantification in Gold by Laser Ablation Inductively Coupled Plasma Mass Spectrometry.

Torvela T, Accotto C, Elliston F: Structural interpretation of the Nadaleen Trend, Yukon.

Matt's CSIRO visit

Matt Grimshaw, a PhD student in the OMG, recently gained a scholarship to undertake a 3-month internship at the Australian Resources Research Centre in Perth. Read about Matt's visit here.
