About the Workshop

The Lake Superior region has long been recognized for hosting world class ore deposit of native copper and Cu(-Ni) sulfides associated with igneous rocks of the 1.1Ga Midcontinent Rift.  The production of low-sulfide palladium-rich ores from the Archean Lac des Iles intrusion near Thunder Bay since 1993 has added a new deposit type to the area. However, some of the most stimulating mineral discoveries in the past decade have been magmatic Ni-Cu-PGE sulfide deposits associated with small ultramafic-mafic conduit-type intrusions, such as Eagle (MI), Tamarack (MN) and Current Lake (ON), emplaced during the early stages of Midcontinent Rift magmatism. 

This is the sixth in a series of professional workshops organized by UMD’s Precambrian Research Center. The PRC welcomes the Society of Economic Geologists as a cosponsor of this year’s workshop.  The goal of the workshop is to familiarize participants with 1) the geological setting, mineralogy, textures, geochemistry and geophysical attributes of magmatic ore deposits, 2) how such deposits are explored, mined, processed, and remediated, and 3) the types and characteristics of Cu-Ni-PGE deposits that occur in the Lake Superior region.

The workshop includes two days of short course lectures presented by internationally and regionally renowned experts on Cu-Ni-PGE deposits.  It also includes five days of field excursions showcasing core displays and mine visits to the most important deposits in the Lake Superior region - including an underground tour of Rio Tinto’s new Eagle Mine.

Notice of Acceptance and Cancellation Policy
Upon receipt of a completed registration form and full payment, a preliminary notice of acceptance will be sent. Because up to 20 PRC member slots are reserved until Friday, June 28th, it is possible that the remaining 30 or so slots may be filled before that date.  If this occurs, registrants will be put on a wait list and any unused member slots will be apportioned after June 28th. The number of regular and PRC member slots remaining will be periodically updated at the top of this page.

A full course refund will be given if notice of cancellation is received by Friday, September 27th.  Our program obligations make it necessary to assess a charge equal to one-half of the course fee for later cancellations.  No course refund is possible after the course begins on October 6th.

Graduate Student Registration
Up to seven graduate students currently enrolled in accredited M.S. or Ph.D. programs in Canadian or US colleges during the 2013-2014 academic year may attend the workshop at a discounted registration rate of $1000.  Student registrations must be accompanied by:

  • a letter by the student briefly describing how the workshop pertains to their thesis research and their career goals.
  • a letter of recommendation from their thesis advisor commenting on the qualifications of the student and the usefulness of this workshop to the student’s thesis research.

Student registrations do not initially require payment of fees.  If more than 7 students register, the seven most qualified students will be chosen and notified on August 30th.  Upon notification of acceptance into the workshop, students will be expected to pay the registration fee by September 20th.

Arriving in Duluth
Duluth, the world’s largest freshwater inland port, is located at the western tip of Lake Superior, midway between the Twin Cities of Minneapolis / St. Paul and the Canadian border.  Nestled in the hills overlooking the largest of the Great Lakes, the city offers breathtaking scenery and serves as the gateway to abundant recreational opportunities. This time of year, the fall colors will be near or just past peak.
