The digital photos washed out the green of the Bobcookite crystals, but they are best seen on the second and third photos. Elsewhere the yellow is mostly Ferrinatrite. Bobcookite is named for Dr. Robert Cook.

"Bob" is probably best known for his column in Rock and Minerals magazine “Connoisseur’s Choice”, which is a featured essay on a single cabinet-sized specimen thought to be the most aesthetic known for the species. This column has made a bimonthly run since 1993. The amount of research that is required for this article every other month is an incredible task. Not only is the specimen described as being the “best of” for that particular mineral, but a thorough description of the mineral’s crystallography, and physical characteristics are given. It doesn’t stop there. Bob describes all the best and classic localities for that mineral and dives into how the mineral occurs and its associations. In short, these columns are an invaluable resource for all mineral enthusiasts. If this was not enough on Bob’s plate, he also serves as executive editor for Rocks & Minerals magazine (25 years) and a professor of geology and Department head at Auburn University in Alabama (35 years). He is now professor emeritus.

Dr. Cook has authored two books: “Minerals of Georgia” a publication of the Department of Natural Resources of Georgia (1978) and Co-authored “Mineralogy of Alabama” for the Alabama Geological Survey (1982).

Of late he is currently Vice President of Exploration for “US Critical Minerals, LLC”, a company devoted to solving the US critical mineral deficiency.

Bob has consulted for the United States Department of Defense (DOD), the National Aeronautics and Space Administration (NASA), the United States Department of Justice (DOJ), and the United Nations (UN) according to US Critical Minerals, LLC.

Colorless prismatic crystals to about 0.75mm in Cuprobismutite with some Quartz. Cannonite is a rare mineral that can be found as an alteration product in copper-bismuth-gold sulfide deposits. The type locality is at the Tunnel Extension No. 1, Marysvale, Piute Co., Utah.

Cannonite is named in honor of the late "Bart" Cannon V (1950-2019), mineral collector and microprobe operator. The microprobe was in his basement along with many other analytical machines.

Curetonite is named in honor Forrest Cureton II (1932-2020) and his son Michael E. Cureton (1960 -). I first met Forrest in Pollock Pines, California in 1997 at the NCMA, when I traded Sincosite for rare minerals from Nevada. Forrest and his wife, Barbara, had a robust mineral dealership, The Cureton Mineral Company, for many years and later sold out to Tony Nikischer of Excalibur minerals. You can hardly view a rare mineral collection and not see many of the minerals with his old labels. Forrest was still field collecting a year or two before his death at 82. I encourage you to read more about Forrest in the Mineralogical Record label archive.
