Minerals, Mining Museum Subject Of Friday Lecture

Advertisement

Dick Zimmerman of the Arizona Mining and Mineral Museum will be a guest lecturer at Gila Community College at noon on Friday. His lecture is open to the public in the Community Room at the college.

Zimmerman will discuss and answer questions about the museum's history from before the turn-of-the-century when Arizona was still a territory.

He will give a PowerPoint presentation on the indoor and outdoor exhibits the museum offers and talk about upcoming projects, such as the semi-annual family days, the annual gem show and annual mineral symposium.

Zimmerman, a retired aerospace engineer, began collecting fossils and minerals 30 years ago as a hobby.

He operates two Wickenburg area mines for collectible minerals. He mines cerussite crystals (lead carbonate) at Amethyst Hill.

"Cerussite looks like glittery snowflakes only much bigger with a bit of a metallic luster," he said.

Barite crystals (barium sulfate) and lead ore come from his Midnight Owl mine.

"I don't like golf, so I dig rocks now and then," Zimmerman said. "I will also speak briefly about the historic and present mineralization in the Payson area."

The Arizona Mining and Mineral Museum is located at 1502 W. Washington in Phoenix. Call (800) 446-4259 or visit http://mines.az.gov/General/museum.html.
