April General Meeting Presentation:

The Precious Metals: What Makes Them Tick?
From Astronomy, Chemistry, Geology, and a side of Einstein!


by Mark Leatherman – CMS Member


Abstract: It is no secret that gold, silver, and platinum have long served as metal nobility due to their rarity, high economic value, ability to resist corrosion, and usage as investments and currency. In the mineral collecting realm, their value easily skyrockets many-fold over metal spot prices if superb crystal forms are involved (and with many potential exquisite specimens being sent to ore crushers in mining operations). With beauty and scarcity being at the forefront of many descriptions (think of the miraculous specimens displayed at the 2017 Denver shows!), it is often easy to overlook what intrinsically makes precious metals exactly that from nature’s point of view. In this talk, we will dig into the atomic nature of these metals, how they were originally made, why they “act” the way they do, how these traits connect into geology and the types of rocks and crystal forms they are found in, and why it is miraculous on why we have them in the first place!


Bio: I have been collecting minerals since elementary school, and rockhounding since I could drive. I started with collecting fossils from outcrops and old quarries in my homeland of northeast Ohio and have collected from and studied mineral deposits in every state I have lived in; a list that includes Michigan, Missouri, Indiana, and Minnesota before coming to Colorado in 2015. I received my B.S. in Geology from Central Michigan University, where I started researching pegmatite minerals, and my M.S. from the University of Missouri-Columbia in geochemistry-economic geology. I have worked for Newmont Gold here in Colorado, as well as an exploration geologist for Duluth Metals, Ltd. scouring the Duluth Igneous Complex - in northeastern Minnesota - for Cu-Ni-Platinum Group Element deposits. I currently teach geology and chemistry courses at Arapahoe Community College in Littleton, and Red Rocks Community College in Lakewood.
