Program: Yuma King—A Potential New Major Graphite-Graphene Deposit in West Central Arizona: An Update
Abstract: Exploration for porphyry copper mineralization on the Yuma King property about 20 km SW of Bouse in west-central Arizona has serendipitously revealed the presence of a large body of graphite-bearing rock that contains a significant graphene component. The graphite-graphene mineralization is inferred to have been formed by frictional heating and shearing associated with SW directed thrusting in early Laramide time circa 89-85 Ma. The graphite is contained in a relatively flat lying dark gray carbonaceous phyllitic meta-mudstone body about 500 feet thick, as established by drilling in June/July 2016. A strongly non-magnetic body believed to correlate with the thicker graphite unit is present in the area Y01 and AV11-02 drillholes. This magnetic low occupies at least a square kilometer and is inferred to be the main ‘guts’ of the graphite-graphene bearing rock. In addition, in about the middle of the 500 foot section, an 80 foot zone of ‘high grade’ carbonaceous rock that averages about 89% black mudstone with significant flake graphene bearing graphite occurs.
The carbonaceous kerogen rich mudrock protolith for the flake graphene was deposited as part of the early to mid Cretaceous McCoy Mountains Formation. The best graphite-graphene (in terms of black color and 'magic tape' field testing for graphene) seems to be associated with shear fabrics presumably associated with the overlying McVay thrust. Raman Spectrometry has confirmed the presence of a significant disordered graphene component.
Speaker Bio: Stan Keith has 40 years of exploration experience focusing on ideas, exploration and discovery for minerals and energy. Stan is a prolific writer and speaker and has authored hundreds of technical reports and publications. His marathon, 3 day, magma-metal series workshops and field trips have been presented to the mineral industry, major companies in the oil and gas industry, and various government agencies. Beginning in 2000, Stan and colleagues began to apply the MagmaChem model to oil and gas, which led to the concept of the serpentosphere, the hydrothermal origin of kerogen and its conversion to graphene. Throughout his career, he continually returns to the reality of the field, testing ideas through geologic mapping. He received a B.S. degree in Philosophy in 1971 from the University of Arizona and an M.S. degree in Geology from the University of Arizona in 1975. Stan and the research team at MagmaChem are known for their ideas and exploration tools, developed from the relationship between magmatism and various kinds of mineral resources, for example, porphyry coppers. These resources now also include petroleum and graphite/graphene.
Change in Dinner Pricing Structure
Our new dinner fee pricing structure is as follows:
Members and Guests of Members: $30
As before, dinner includes two drink tickets thanks to our generous sponsors. Annual membership is still $25. Memberships from other local sections will be recognized as qualifying for the member dinner price.
Boy Scout Mining in Society Merit Badge Event!
Freeport is sponsoring another Boy Scout Mining in Society Merit Badge Workshop in Miami on Saturday, 22 October 2016. It will be held at the Museum (old high school) from 8:00 AM to 3:30 PM.
Will and Pam Wilkinson are looking for volunteers to help man the different stations where Scouts will work on requirements to earn the merit badge. Please let us know if you are available to volunteer!
Know Any YOUNG Miners?
Tell them about Young Miners of Arizona! Initiated in 2015, this new Arizona SME Section targets members with 15 years or less experience in the mining industry. It is a great transition for newly graduated students to connect with their peer group. Click the links below for more information!
