Speaker Spotlight: David Cooke

24 January 2019

David Cooke is the Director of ARC Industrial Transformational Research Hub for Transforming Mining Value Chain at the University of Tasmania. David and his research team have been researching porphyry copper and epithermal gold deposits of the circum-Pacific region for over 30 years. They have investigated the geodynamic environments of mineralisation, intrusive history and the magmatic-hydrothermal transition, fluid compositions, ore-forming processes and genetic associations between porphyry and epithermal systems.

Over the past 14 years, David and his team have been studying geochemical halos to porphyry and epithermal deposits, developing new exploration tools for the minerals industry. This work, sponsored through AMIRA International, led to the team being awarded the inaugural AMIRA International Award for Geoscience Research Excellence in 2012.

David is an associate editor of Economic Geology, and is Director of both the TMVC ARC Industrial Transformational Research Hub, and CODES – the Centre for Ore Deposit and Earth Sciences. David received the Society of Economic Geologists’ Thayer Lindsley lecturer award in 2005, the SEG Silver Medal in 2013, and the Australian Academy of Science’s Haddon Forrester King Medal in 2018.

David will present his paper on Friday 5 April, 2019.

We recently asked David some questions about PACRIM. See his answers below:

1. Can you provide an insight into what your presentation will cover at PACRIM 2019?

My talk will provide attendees with an overview of the exploration footprints of porphyry deposits. The presentation will begin with a review of the conventional geophysical and geochemical techniques we use to discover porphyry deposits. I will then introduce new geochemical exploration techniques that we have been developing that allow detection of the geochemical footprint of porphyry deposits at much greater distances than previously attainable. I will then demonstrate the capacity of this new technique through a case study of its application to aid detection of the giant Resolution porphyry Cu-Mo deposit in Arizona.

2. What do you hope delegates will learn/take away from your presentation?

I hope that delegates will see that these new exploration tools have the potential to aid them in mineral exploration, particularly with regards to decision-making early in exploration campaigns in areas ranging from partially to totally covered.

3. What are you looking forward to most about PACRIM?

I am looking forward to the opportunity to learn about the latest advances in mining and exploration around the Pacific Rim, and also to the networking opportunities that this meeting will provide.

4. What is the biggest challenge you have faced in your career?

Working underground in a mine with active geothermal discharges; the ambient temperature locally reached 70C, with 100% humidity. Very extreme working conditions!

5. What advice would you give to a young professional beginning their career in the resources sector?

Take every opportunity to visit as many ore deposits as you possibly can. The best geologists have seen (and understand) the most rocks.
