Advances in Exploration Geochemistry

Course Instructor:
Sarah Rice, ALS Global

Course description: 

Geochemistry is a primary tool for mineral exploration. Modern technology offers a myriad of options for geochemical sample analysis.  This one day short course will address appropriate types of sample preparation and analysis for geochemistry of unaltered, altered, and mineralized rocks in mineral exploration. The course will cover various procedures for sample preparation, methods of analysis, combinations of analyses, and precision of data.
The Advances in Exploration Geochemistry portion of the short course will include presentations describing new and improved analytical techniques that have significantly affected surficial exploration for buried deposits, isotopic analysis providing new vectors to mineralization and insights into ore forming processes, and new horizons in mineralogy-geochemistry integration in exploration. Course participants should have a basic understanding of geochemical prospecting but we won’t hit you with any mass balance equations or solubility constants.  The course is designed for geologists, geochemists and prospectors interested in learning about recent advances in this field.

Application of Airborne Geophysics to Minerals Exploration in Alaska

Course Instructors:
Ken Witherly, Condor Consulting, Inc., Lakewood, CO
Abraham Emond, DGGS, Fairbanks, AK

Course description: 

The State of Alaska has supported airborne geophysical surveys in the state since the mid-1990s. Surveys flown have been primarily concurrent EM and magnetics surveys but some mag-only have also been carried out. While primary flown to help the minerals industry map geology and assist in locating new mineral deposits, these surveys have also assisted in environmental and geotechnical assessments, including the mapping of permafrost zones in developed and semi-developed areas. This survey program is the most extensive of its kind in the country. While the main focus of this workshop will be on the state-backed airborne EM and magnetics surveys, the USGS-supported aeromagnetics and gravity programs will also be discussed as they are in many ways complementary to the state’s program.

The workshop will be made up of the following segments:
-review the theory behind the geophysical techniques used
-discuss the state program and how data can be accessed
-present examples of using these surveys for exploration in Alaska for minerals, environmental and geotechnical purposes
-provide a series of case studies from Alaska and the Yukon where airborne geophysics has been used to help locate/define mineral deposits

 Level of knowledge-the geophysical component will be suitable for a geological audience


 Registration Available Soon!

Abraham Emond is responsible for the distribution, promotion, publication, and archiving of the DGGS geophysical data collection. These data are critical to Alaska's resource exploration, transportation, and environmental stakeholders. He also manages the acquisition of new geophysical data for the benefit of the State of Alaska. DGGS data collection primarily contains high quality airborne magnetic, electromagnetic, and radiometric data.

Prior to joining DGGS, Abraham worked as a geophysicist for Rio Tinto and various junior exploration companies. He earned a Bachelor’s Degree in Geophysics from Colorado School of Mines and Master’s Degree in Geophysics from the University of Utah.

Abraham enjoys exploring Alaska’s riverside geology with his wife (a geologist) and two young children.

Sarah Rice started her career as a research laboratory assistant at Queen’s Facility for Isotope Research, working on applications of isotopic analysis in exploration geochemistry. She moved on to ALS Geochemistry as a technical contact in client services in 2011, and currently works as Senior Geochemist in Vancouver, Canada, partnering with clients to design custom-fit analytical solutions for complex projects and providing training and development both internally and externally. She has a B.Sc. in geology (2007) and a M.Sc. in geochemistry (2012) from Queen’s University, Canada.

Ken Witherly graduated from UBC (Vancouver Canada) with a BSc in geophysics and physics in 1971.

He then spent 27 years with the Utah/BHP Minerals company during which time as Chief Geophysicist, he championed BHP’s programs in airborne geophysics which resulted in the development of the MegaTEM and Falcon technologies. In 1999, Ken helped form a technology-focused service company that specializes in the application of innovative processing and data analysis to help drive the discovery of new mineral deposits.
