New exhibit of historical mining maps opens in Tucson

Arizona Geology Blog - Tue, 2015-06-23 19:42
 The Arizona Historical Society has opened a new exhibit in Tucson of the map collection of Robert Lenon.
Robert Lenon was a surveyor and mining engineer from Patagonia, Arizona. In addition to creating a vast number of maps depicting mining resources in the Sonoran desert region of Southern Arizona and Northern Mexico, Lenon collected historical maps dating back to the mid-1800s. The exhibit features highlights from the map collection and items from Lenon's engineering office.

Admission to the museum is $1. The museum is located at 949 E. 2nd Street Tucson, AZ 85719
Parking is one block west of the museum in the Arizona Historical Society garage at the northeast corner of E. 2nd Street and N. Euclid Avenue. Use the E. 2nd Street entrance to the parking garage. Parking is free for museum and library visitors (validated in the museum).

Bill introduced to overturn Resolution copper mine land exchange

Arizona Geology Blog - Sat, 2015-06-20 15:24
Two Arizona congressmen, Raul Grijalva (Tucson) and Ruben Gallego (Phoenix), introduced legislation to reverse the federal land exchange that is allowing the giant underground Resolution copper mine to be developed near the town of Superior. 

The land swap was approved last year along with a number of other land actions as part of a large defense bill.

The bill traded 2,400 acres of federally owned land for 5,300 acres acquired by Resolution Copper of private recreational, conservation and cultural lands across Arizona identified by conservation and other groups as priorities.

The San Carlos Apaches oppose the mine because of concerns about continued access to the Oak Creek Flat and Apache Leap areas [top right].   Requirements of the land exchange legislation according to Resolution Copper are that:
  • The USFS must complete a FEIS before exchange of the lands.
  • Resolution Copper will convey 110 acres of company owned land, which will be combined with 697 acres of federal land to create the Apache Leap Special Management Area (SMA). This SMA permanently protects Apache Leap and the legislation requires a management plan be developed with stakeholder input.
  • Resolution Copper must maintain public access to Oak Flat Campground (post FEIS) until it is no longer safe.
  • Increase consultation with affected Native American tribes to find mutually acceptable measures to address concerns.
Specifically, H.R.2811 would "repeal section 3003 of the the Carl Levin and Howard P. "Buck" McKeon National Defense Authorization Act for Fiscal Year 2015."

State Geologists field trip into Petrified Forest National Park back country

Arizona Geology Blog - Sat, 2015-06-20 11:48
The post-meeting field trip for the 107th Annual Meeting of the Association of American State Geologists (AASG) went to Petrified Forest National Park and Meteor Crater last Thursday.











Park naturalist and paleontologist Adam Marsh led the 50+ participants on a back country hike to an early Triassic 'dying ground' site that he and his team are currently excavating.   The dig area was literally covered with weathered-out bone fragments and teeth from a number of pre-dinosaur fauna as well lots of petrified wood. The prime excavation site was exposing more intact materials.   Despite the 96F temperature, we had a difficult time getting everyone to leave the stop and hike back to the bus.

AZGS hosted the meeting in Flagstaff starting last Sunday and running through Thursday.

State Geologists annual meeting underway in Flagstaff

Arizona Geology Blog - Wed, 2015-06-17 13:58


AZGS is hosting the 107th Annual Meeting of the Association of American State Geologists (AASG) in Flagstaff this week.   Over 150 attendees are participating from state geological surveys, federal counterparts, professional organizations, and industry.     We have a variety of technical sessions on geoscience topics including induced seismicity, mineral resources, ground collapse, sustainability of state surveys, groundwater, and data preservation.

USGS Acting Director Suzette Kimball laid out a proposal for expanded collaboration between USGS and State Geological Surveys on a number of priority areas around resources, hazards, mapping, and environmental topics. 

A field trip to Grand Canyon on Tuesday, provided opportunities to discuss land use management, geology in national parks, outreach and education, as well as giving the attendees an introduction to Arizona geology.

Wildcat Silver changes name to reflect growing interest in lead, zinc

Arizona Geology Blog - Tue, 2015-06-09 06:17

Interesting news item that Wildcat Silver Corporation has changed its name to AZ Mining Inc.  The new website is http://www.azmininginc.com/.
 
The company said the change "reflects both the Company's focus on its Hermosa property located near Patagonia in southern Arizonaand the poly-metallic nature of the mineralization on the two current projects."   

Richard Warke, the Company's Chairman and CEO said, "The recently released drill results from the first five holes on our Hermosa North West drill program confirm we have the makings of a potentially significant zinc/lead/silver deposit on our hands. As a consequence, we felt this was the right time to re-brand the Company given its current focus on North West and our history and commitment to mineral exploration in Arizona."
