Central Colorado Humanists: Sunday Science

March 1 @ 10:00 am - 11:30 am

On the first Sunday of every month, join the Central Colorado Humanists for Sunday Science.

About the Event

Come join the Central Colorado Humanists as they feature their own CCH members and friends in a variety of science-oriented talks and discussions. Sunday Science covers topics in all areas of science, hard and soft, from psychology to climate change, plant ecology to NASA space missions. It is also a great opportunity to meet fellow Humanists, make new friends, and learn about new ideas. All are welcome!

Each presentation is informative and features a science topic understandable by both scientists and non-scientists. A question and answer period will follow the talk. Light refreshments will be available, and you are invited to bring a plate of goodies to share. And, in the interest of our environment, please consider carpooling and bringing your own reusable coffee mug or beverage container.

Doors will open at 9:30am so participants can have refreshments and be seated when the program begins promptly at 10am. Admission is free and the public is welcome. Please join us!

This Month: Modern Gold Mining – The “Hole” Truth


The talk will discuss common methods that today’s gold mining industry uses to extract and process ore, including open-pit and underground mining techniques, as well as post-mining reclamation. The intent is to be informative and factual, with no intention of trying to either glamorize or vilify the industry. Mr. Leach will draw on his nearly 25 years of experience as a mine geologist for Newmont Mining Corporation to describe how mining operations are conducted. The talk will cover aspects of so-called “hard rock mining”, as opposed to placer mining, which is quite a different animal.

Speaker Bio:

Brad Leach earned his BS in Geology from The College of Wooster in Wooster Ohio, and an MS in Geology from Vanderbilt University, Nashville, TN. After teaching high school Earth Science for a few years, he took an entry-level geologist job with mining firm Newmont Mining Corporation in Elko, Nevada. Much to his surprise, he ended up staying with Newmont for his entire 25-year career, where he had the opportunity to work in nearly all facets of mining geology in countries all over the world. He is retired now, and moved to the Salida area in 2013. He enjoys being involved with several volunteer activities in the community, and enjoys hiking and fishing as well as amateur sports car racing.
