Speaker Spotlight: Dave Craw

10 January 2019

Dave Craw’s presentation at PACRIM is titled: Orogenic deposits: new approaches to old goldfields in New Zealand.

Dave is the Professor of Economic Geology at University of Otago, New Zealand. Along with numerous students, he has been conducting research on various aspects of orogenic gold deposits for the past 35 years. His research topics have ranged from regional geological settings and specific deposits, fundamental processes of fluid flow and gold mobility in active and ancient orogenic belts, mineral processing mineralogy, and downstream environmental effects and mitigation of gold mining activity.

Dave will present his paper on Thursday 4 April, 2019.

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

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

I will talk about New Zealand orogenic gold deposits in the context of SW Pacific Rim geology. Traditional exploration targets have focussed on quartz vein systems. However, the target is enhanced by considering lower grade hydrothermal alteration zones with or without associated quartz veins. From this perspective, structural control is the key feature: both local and regional.

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

The importance of structural control and tectonic setting.

New Zealand is prospective for new discoveries, and also is an excellent place to gain new understanding of the processes of orogenic gold mineralisation.

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

I enjoy discussions with a range of people, from mine geologists to senior academics, especially when they disagree with me. That is when progress is made.

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

Finding time to keep up with the rapid changes in data, information, and knowledge in economic geology, and gaining the research funding to do the work that these changes have inspired.

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

Get as much hands-on experience with as many different deposit types as possible. Work in different stages in resource development, from exploration to mine site environmental issues and mine closure; they all involve the same rocks and minerals.
