MDRU's 2012 Roundup Reception
MDRU hosted a reception for representatives from MDRU's Foundation Members, Corporate Members, researchers, staff and students on Sunday, January 22, 2012 to kick off Roundup festivities in celebration of MDRU's 23rd year. Held at the swanky Westin Bayshore Hotel's International Suite, the reception brought together students and researchers from past MDRU initiatives, many of whom are now leading the industry as exploration managers. MDRU Director Craig Hart delivered remarks highlighting emerging MDRU research projects and upcoming sponsorship opportunities, providing an exciting glimpse into MDRU's future for 2012.

Craig Hart talking about the PIMS project at Tuesday's Technical Session.

At Tuesday morning's Technical Session, Public Geoscience: Preparing for the Next 100 Years, Craig Hart presented results from a recent MDRU project PIMS ‐ Porphyry Indicator Minerals as a New Exploration Tool for BC Porphyry Deposits. This pilot project highlighted the promising early results from research by Farhad Bouzari, which identified easy methods for characterizing the intensity of alteration in common resistate accessory minerals from porphyry systems.

MDRU hosted a Trade Show booth with the Department of Earth and Ocean Sciences during the multi-day event. Thanks to those that dropped by and chatted with the many graduate students and researchers at the booth.

Leapfrog 3D Structural Modelling Short Course
Following a busy week of Roundup activities, Leapfrog representative and expert user Dr. Andy Abraham, delivered a rousing review of Leapfrog's capabilities through a series of practical exercises and theoretical discussion to a select audience of MDRU students, corporate members and professionals from Teck Resources Ltd., Kinross Gold Corp., Castle Peak Mining Ltd., and Goldcorp Inc. Leapfrog's value in a competitive spatial visualization market is its rapid 3D visualization capabilities, and the ability to model geological data and predict ore geometry through the input of structural controls. MDRU has been proud to include Leapfrog among the many investigative resources available to our students and researchers.

Yukon Gold Rocks

Murray Allan and Tim Wrighton panning for gold in the Yukon.

The Yukon Gold Project team braved -35C temperatures as it held another successful technical meeting for sponsor companies in Whitehorse in November. The project has provided significant advances in the understanding of the nature and timing of mineralization in the Dawson Range and White Gold Districts. In addition, Project Leader Murray Allan gave a summary talk on the metallogeny of the project area at the Geoscience Forum, 19-23 November 2011, Whitehorse, Yukon. He also presented this talk later in December at the Vancouver Mining Exploration Group (MEG) "White Hot Yukon – Rocks and Beyond " short course. Craig Hart also presented a talk at the workshop, entitled Tintina Gold Province - The Next Generation. Both talks are available to members on the MDRU website.

Graduate students on the Yukon Gold project presented some of their research as posters at the Yukon Geoscience Forum. All of the posters listed below are viewable by MDRU Members on the Members Area of the website at www.mdru.ubc.ca.

UBC professor Kenneth Hickey and Post-Doctoral Fellow Shaun Barker ran the event for the sold out group of 60 participants. The course was sponsored by the Geological Association of Canada®, Aurora Geosciences, and Yukon Geological Survey.

Northwest Mining Association Conference, 30 November–2 December, Reno, Nevada

Craig Hart, Karie Smith, and PhD Candidate Trent Newkirk managed the MDRU booth at the Northwest Mining Association Conference held at John Ascuaga's Nugget Casino Resort. This conference gives MDRU the opportunity to reinforce its connections with US-based companies and representatives from Nevada's many gold mines.

Craig Hart, Karie Smith, Thomas Bissig and Greg Dipple attended the Prospectors & Developers Association of Canada Convention at the Metro Toronto Convention Centre, Toronto Ontario, March 4-7, 2012. MDRU and EOS made a big splash with a shared booth and flew the flag high.

UBC – SEG Student Chapter Update

Volcano in the Philippines.

The UBC SEG Student Chapter is stepping into high-gear with the organization of the 2012 international field trip to the Philippines in May 2012. The trip will include seven mine visits and exploration properties, and exciting geological discoveries such a hike of Mount Pinatubo, and a visit of the Rice Terraces World Heritage site. The trip will be attended by eight students from the UBC-SEG Student Chapter, eight industry participants and some graduate students from the University of the Philippines.
The Chapter also recently conducted short courses including an ioGas geochemistry workshop, training in portable and bench-top XRF apparatus, and hosted a presentation on El Indio by SEG Honorary Lecturer Dr. Kevin Heather.
Upcoming events include a field trip to the Gibraltar Mine, a student-industry mixer in the first half of April. More information on our website http://seg.eos.ubc.ca/

Yukon Gold Project Researcher Murray Allan and his wife, Sanya Pleshakov, are the beaming new parents of the department's first 2012 baby: Nicolaas Alexander Pleshakov Allan. Nico arrived in the midst of a blustery snowstorm, shortly after midnight on January 19, 2012. The department are thrilled for Murray and Sanya as they take on this new chapter!

Congratulations also to Abdul Razique and family as they are now blessed with a healthy son. Zubaida and son Saif-ur-rehman are both now at home and in good health.

And finally, to add to the good news, Peter and Christine MacDonald were overjoyed to welcome their first child, son Henry Russell MacDonald, born February 11th.

Congratulations and best wishes to both the new and veteran parents in our group!
