New Project Opportunities

MDRU is initiating several new and exciting collaborative research projects with industry for 2012 and beyond. We are looking for indications of interest from those companies who wish to consider participating. In particular we are planning to expand our successful "PIMS-Porphyry Indicator Minerals" project to include industry participants, follow-up with a second and expanded phase of the "Turkey-Tethyan Metallogeny Project", and to initiate a new "Carbonate Alteration Footprints" project to take advantage of newly developed in-house analytical technologies. Additionally, the next phase of the "Carbon Sequestration in Mine Wastes" project will go forward in 2012, and we will have a project on "Gold Grain Characterization" to supplement work we've been doing with placer gold geochemistry. As always, we are keen to start new projects related to "Kimberlites, Xenoliths & Diamonds". Lastly, we still have a couple of spots left for participants in our "Colombia Gold & Porphyry Project". We look forward to working with those interested companies in developing objects that will frame the final proposals. Read More.

The UBC SEG Student Chapter

SEG group at Myra Falls, Vancouver Island

The UBC SEG Student Chapter continues to provide many exciting activities for its members. Earlier in 2011 the chapter ran three field trips; a major trip to the Major Ore Deposits of the Yilgarn Craton of Western Australia; an trip touring the key geological and ore deposit features of the NW USA; and a short, four-day trip to investigate Sicker Group and VMS potential on Vancouver Island. Since September this year a weekend trip to Myra Falls VMS deposit on Vancouver Island was run and attended by 11 students (photo at left). Several short-courses are being organized for the coming months including; a tour of the ACME laboratories; a structural geology course to be run by SRK Consulting; and a geochemistry software course by ioGlobal. Finally, the Student Chapter would like to announce that our 2012 International Field Trip will be to the Republic of the Philippines! This trip will focus on Cu-Au porphyry systems but will also include low-sulphidation epithermal gold as well as chromium deposits. This is exciting news and a call for industry participants will be forthcoming.

Fluid Inclusion Laboratory … in High Definition

Fluid Inclusions

MDRU's fluid inclusion facility recently received a boost, with the arrival of a new high-resolution digital video and visualization system to complement its high-quality microscope and heating-freezing equipment. The facility is designed for fluid inclusion analysis in the temperature range -196°C to 600°C which makes it suitable for fluid inclusions in almost all ore deposit environments. The optical system also transmits and detects light at near-infrared wavelengths, allowing users to detect and analyze fluid inclusions in some opaque minerals such as enargite, chalcocite, stibnite, molybdenite, and wolframite. For more information about the fluid inclusion facility, contact Murray Allan.

KXD - Kimberlites, Xenoliths & Diamonds

Kimberlite thin section image

UBC's Diamond Exploration and Volcanology laboratories are open to new collaborations with industry sponsors to study kimberlites, kimberlite-derived mantle xenoliths or diamonds. Kimberlite-specific studies of volcanic facies can constrain a geological model of the pipe which is essential for accurate resource estimates and mine planning. Petrographic and thermobarometric studies of mantle xenoliths can assess diamond potential by mapping the "diamond window" below the kimberlite. Diamond research can also constrain the parent rock for the diamonds to provide customized exploration methods that use indicator minerals for specific areas. MDRU has a long history of collaborative KXD research projects. Check out www.mdru.ubc.ca/home/research/diamonds/ for current and previous projects.

MDRU Porphyry Footprints Technical Meeting

The Final (year 3) MDRU Porphyry Footprints Technical Meeting was held in Butte, Montana in mid-Sept.  The meeting included a regional tour of the extensive variations in the Butte alteration footprint.  Results of the research was presented by John Dilles, Scott Halley, and Richard Tosdal to the assembled industry sponsors.  The results from MSc theses by Tatiana Alva (MDRU), Julia Cohen (OSU) were also incorporated.  The meeting also included a workshop on using ioGas software to interrogate the data from the project.

This project was sponsored by Barrick Gold Corp., BHP Billiton Ltd., Teck Resources Ltd., Freeport-McMcoRan Exploration Corp. and Vale Exploration Canada Inc.

Esther in the field

This report presents the preliminary interpretations of an ongoing PhD thesis project by Esther Bordet. The report documents new mapping and proposes an improved stratigraphic and structural model for the Eocene period in the Nechako Basin. Characterization of the nature, thickness and structural framework of Eocene volcanic rocks in the Nechako region provides new insights into the area's Early Cenozoic history and will provide a more robust framework for future mineral and oil & gas exploration in the Nechako region.
