The Arizona Geological Society is grateful to Freeport-McMoRan Copper and Gold for their generous support of our student members.
Freeport-McMoRan Copper and Gold is sponsoring student dinners at the 2014 AGS monthly meetings.
On Saturday, April 26, 2014, the AGS spring field trip is planned for Freeport-McMoRan’s Christmas porphyry copper deposit in Gila County, Arizona.
The Christmas deposit is situated at the southeastern end of the Dripping Springs Mountains and is one of the last largely undeveloped deposits remaining in the prolific porphyry copper province of southeastern Arizona. The planned program will include an examination of core and stops at significant geologic outcrops in the vicinity of the mine.
