NASA and industry partner to impact asteroid into Arizona to mine for rare earths

Arizona Geology Blog - 8 hours 20 min ago
NASA and a consortium of mining companies announced plans today to capture a metal-rich asteroid  as it passes by Earth, with the intent of sending it to Arizona, where it will be mined for rare earth elements.  Rare earth minerals are in increasing demand for technology applications including hybrid cars and cell phones, but China dominates the world market raising concerns about supply disruptions.NASA proposes sending a small rocket to asteroid Heise-2014 discovered by an amateur astronomer last year who is the world's wealthiest breeder of thoroughbreed seahorses, that would nudge it out of orbit and towards lands controlled by the McCrory Asteroid Mineral Alliance (MAMA) west of Phoenix, Arizona.   A company spokesperson downplayed the chances that the asteroid would be significantly off target when it lands (or "impacts" as the news media says).    Company president  Art McCrory, issued a statement from at an undisclosed location on the Canadian shield, saying,  "A gazillion tons of rock and metal hurled towards Arizona at 25,000 miles per hour, what could go wrong?"   He closed by wishing us luck and asking that we let him know how it worked out before retreating to his underground bunker with the former Miss Rhenium of 2006.
NASA noted that Meteor Crater, Arizona was formed by an impacting body without damaging property 50,000 years ago, so there should be no worries this time around either.   In fact, NASA and MAMA may sell tickets to view the landing from ringside seats.  Dark glasses will be provided to spectators.
That's the news this April 1, 2015.    [Happy April Fool's Day!]

According to the announcement from the governor's office, Senate Bill 1441 was sponsored by State Senator Steve Smith after a fourth-grade class at Copper Creek Elementary School in Tucson had the idea and reached out to him about it.

“These students helped create a bill that had bipartisan support and will now be forever part of Arizona’s history,” said Governor Ducey. “A crucial driver of our economy, copper is represented on our state seal and is one of Arizona’s ‘5 C’s’ along with climate, cattle, citrus and cotton.

Arizona produces nearly 2/3 of all the copper used in the U.S.

Battle over museum transfer heats up

Arizona Geology Blog - Thu, 2015-03-26 20:35
The bill to transfer the former Mining & Mineral Museum from the Arizona Historical Society to the Arizona Geological Survey is generating heated debate.   Although both AHS and AZGS have taken official neutral positions on SB1200, supporters and opponents are squaring off.  [Right, artists rendition for the proposed Centennial Museum to be built in the former museum space The building is currently vacant.]   The Arizona Capitol Times posted the most detailed report on the museum transfer published so far, by reporter Rachel Leingang at
http://azcapitoltimes.com/news/2015/03/26/bill-would-reopen-mining-museum-but-budget-problems-remain/

The Friends of the Arizona Historical Society circulated a letter urging opposition to the bill, arguing 
  • The Historical Society is efficiently and effectively maintaining the Mining and Mineral Museum  and it should stay where it is.
  •  Leaving the Museum where it is currently will allow it to progress and flourish.
  • It makes sense and is good government for the Museum to stay with the state agency that runs museums.   
The lobbyist for AHS also raised the issue with the House Appropriations Committee that AZGS does not run museums.


Proponents of the transfer sharply disputed the claims in the letter from the Friends of the AHS during the same hearing, particularly the statement that AHS inherited a museum that was already closed.   In fact, AHS took the Mining and Mineral Museum in 2010 and shut it down in 2011 in anticipation of converting it to the Centennial Museum.


Today, the proponents started a petition drive aimed at the Governor, calling on allies to counter the letters and calls coming from the other side.

In an email sending around the petition that we received this afternoon, supporters are told:


"Feel free to print copies and get signatures wherever you can. At work or at school.  In the supermarket or stuck in traffic.  On the golf course, or at the gym.  Chase down the fishing boat or ATV ahead of you this weekend.
Put some on telephone poles and restroom walls.  Ask K Mart and Costco to put it on their bulletin board. Have kids give one to the teacher. Take some along when you walk the dog (possible dual use). Offer prison inmates a cigarette for a signature. Tell the kids they don't have to do their homework if they sign. Tell the mail man you will never let the dog out again if he / she signs. Ring doorbells and tell people they won the Readers Digest Sweepstakes (just sign here).
Be creative. Be sneaky. Be determined. BE SUCCESSFUL"  SB1200 must now go to the full House for consideration.

Dropping rent provision keeps museum bill alive

Arizona Geology Blog - Wed, 2015-03-25 19:54
The Arizona House Appropriations Committee today approved SB1200, transferring the former Mining & Mineral Museum building to AZGS to create a new Mining, Mineral, and Natural Resources Educational Museum.   It also transfers $428,300 per year in funding from the Arizona Historical Society budget to AZGS to pay for the rent and salary of one curator.

The bill had been held due to amendments in the House and Senate that would have waived the $360,000 per year rent on the building for two years, with those funds to be used for restoration, maintenance, and operations.   However, waiving the rent charged to AZGS meant the State would have to find those funds elsewhere, and thus put a significant price tag on the bill.     To get the bill through the Committee, the sponsor, Sen. Gail Griffin agreed to removing the rent waivers, making it nominally revenue neutral.   The bill as it stands now, would provide funds to pay the rent and salary and benefits per year for one curator but nothing else.

There is also a report from last December estimating the cost of building upgrades at $2.1 million to reopen the facility for its new functions.  Those costs are not considered in the revenue neutral determination.

If signed into law, AZGS will be responsible for finding funds to develop exhibits for the now empty building, create the education program, stock a gift shop, hire gift shop staff and any other staff such as a museum director or fund raiser.   Supporters of the former Mining and Mineral Museum assured the committee that the gift shop will make the museum self-supporting and that no more paid staff are needed beyond that to make this a world class destination site for tourists.  

As the agency that will be responsible for creating something the Historical Society could not achieve with more staff and funding than we will be given, we are not so confident.   If assigned this task, AZGS will do the best we can with the resources we can find. But we need to temper expectations, especially from those who think a new museum can be operating in time for the opening of the school year in August-September, if we took possession in July.

The bill has to go to the full House for approval and then to a Senate-House conference committee to reconcile the different versions.

Calling for support to reauthorize the National Geological & Geophysical Data Preservation Program

Arizona Geology Blog - Sun, 2015-03-22 14:43


Reauthorization of the USGS National Geological and Geophysical Data Preservation Program (NGGDPP) is coming up in Congress and the State Geological Surveys are lining up support from geoscience data users.   We are asking our data users to add their names to a letter to Congress supporting reauthorization.
AZGS has been one of the most successful  competitors for limited federal funds.  The program requires that we put up Survey matching funds, 1 to 1 for each federal dollar.  Our focus the past four years has been digitizing the massive files we inherited from the merger of the Arizona Dept. of Mines & Mineral Resources.    We have ~800,000 pages of mining and mineral resource files, 10,000 maps, and 7,500 historical photos. [See photos]  In addition to scanning and digitizing at the highest resolution the software can handle, every document and map is georeferenced and documented with extensive metadata for search and discovery.   All data are posted online for free viewing and downloading at http://minedata.azgs.az.gov/.
The letter the State Geologists are circulating says archived and heritage geological and geophysical data can yield energy and mineral discoveries worth billions of dollars and generate tens of thousands of jobs. The NGGDPP supports important Federal-State partnerships that achieve mutually beneficial goals related to the rescue and accessibility of invaluable geoscience data.

Geoscience data are critical and of immediate concern to the Nation’s economy, well-being, and security. Examples include the following:


·         Location, abundance, sustainability, and quality of water supplies
·         Domestic energy sources, such as oil, gas, coal, geothermal, and renewables; reduction of carbon emissions
·         Domestic sources of metals and critical minerals
·         Identification, mapping, and prediction of geologic hazards such as earthquakes, volcanic eruptions, sinkholes and landslides
·         New technological breakthroughs require re-examination of samples and data; data historically deemed insignificant may become paramount to new discoveries
·         Training the next generation of geoscientists, especially geologic mappers

All of these issues rely on the analysis of geological and geophysical samples, collections, and data that already exist. They have been acquired at the cost of hundreds of millions of dollars and in most instances are irreplaceable. Regrettably, these vital materials are often in poor states of preservation and access, and in danger of permanent loss. Many of this nation’s geological data repositories, most of which are maintained by State Geological Surveys, are now at or near their storage capacity. Some have exceeded their capacity and are relying on temporary, non-climate-controlled portable storage. Expansion of these facilities requires significant capital costs. While industry and government have made substantial investments to acquire geoscience data and collections for over 150 years, volumes of expensive and arduously obtained subsurface information are currently at risk of disposal or ruin. Once these data are lost, they probably will never be replaced.

Congress established the National Geological and Geophysical Data Preservation Program (NGGDPP) through the National Energy Policy Act of 2005 [PL 109-38, Sec. 351] to address these issues. We acknowledge and support the role of the US Geological Survey (USGS) in administering this program, which includes the development and compilation of state and federal data inventories, data standards, creation of a National Digital Catalog, strategic planning, and collaboration regarding preservation techniques. This vital work can continue, however, it requires Congressional reauthorization.

We commend your efforts to strengthen our nation’s capacity to address the challenges associated with energy, as well as critical and strategic mineral resources. The reauthorization of the NGGDPP will greatly assist in these endeavors.

Federal fracking rules: nothing to see in Arizona

Arizona Geology Blog - Sun, 2015-03-22 13:48

The Bureau of Land Management issued rules last week for hydraulic fracturing on Federal and Indian lands.  This is mainly aimed at all the wells being drilled into shales for oil and gas.  There is no shale oil or shale gas development in Arizona, and the potential has been generally viewed as minor.  All of the oil and gas production in Arizona is from a small number of wells (~16) on the Navajo Reservation just south of the Utah border.   A few exploratory wells have been hydraulically fractured in the past 50 years in the state for testing but none were ever put into production.  No producing well in Arizona was fracked.    [Right, diagrammatic cross section showing the horizontally drilled and fractured producing section, below the aquifer.

The Mining Law Blog summarized the final rules requiring the operator to: "submit additional information with its APD including wellbore geology, location of faults and fractures, and the depths of all usable water; implement and monitor a cementing program during well construction; perform a mechanical integrity test; store waste fluids in “rigid enclosed, covered or netted and screened above-ground storage tanks; and disclose chemicals used in the fracking activity."

The Arizona Oil & Gas Conservation Commission does not regulate wells on Tribal lands.    AZGS provides the administrative and technical support for the Commission.

Museum transfer bill passed by Arizona House committee

Arizona Geology Blog - Tue, 2015-03-17 08:04
The Energy, Environment, and Natural Resources Committee passed the museum transfer bill, SB1200, by 9-0 on Monday.  It now goes to the full House for approval and then on the to Governor for signature.

SB1200 transfers the building that housed the former Mining and Mineral Museum from the Arizona Historical Society to the Arizona Geological Survey to be converted to a Mining, Mineral, and Natural Resources Education Museum.

The building has been vacant and unused since it was closed in 2011 in preparation for converting it to a centennial museum.  However, private funding was not forthcoming and Gov. Brewer had committed to not using state money for it.

SB1200 sponsor Sen. Gail Griffin yesterday said she was confident the private sector would provide $2.5 million to complete the necessary building upgrades to open the new museum.

AZGS has taken a neutral position on the bill due to the uncertainty over funds needed to open and operate the facility.

Centennial museum bill hearing scheduled in State House

Arizona Geology Blog - Thu, 2015-03-12 16:51
The Arizona House Committee on Energy, Environment, and Natural Resources will hold a hearing on Senate Bill 1200 on Monday, March 16, in hearing room HHR1 in Phoenix at 2 p.m.

SB1200 transfers the former Mining and Mineral Museum building and collections to the Arizona Geological Survey to be re-opened as the Mining, Mineral, and Natural Resources Education Museum.      The language in the bill is taken almost verbatim from the language establishing the Centennial Museum in 2010 that was never built due to lack of funding. [Right, view of main floor in former Mining & Mineral Museum. Credit, Jan Rasmussen].  The museum was emptied and many exhibits and displays loaned or given away and specimens on loan returned to their owners.

The new museum is expected to include agriculture, livestock, timber, and tourism in addition to the mining and mineral themes from the old museum that was closed in 2010.  A advisory council appointed by the Governor, representing all those stakeholder constituencies would oversee development of the new museum concept.

The Senate approved the bill two weeks ago, with a floor amendment exempting AZGS from paying rent on the building for the first year, so that those funds could be used for salaries, operations, maintenance, capital costs to re-open the building, creating displays, and education programs.  The museum is expected to be self-supporting after that first year, except for one state-funded curator.

US89 readying to re-open after two years of reconstruction following massive landslide

Arizona Geology Blog - Wed, 2015-03-11 20:08
 ADOT announced today that US89 will re-open on March 27, more than two years after a landslide tore up a section of the highway causing $45 million in direct costs and uncounted economic losses to the city of Page and commercial traffic routed across a long detour.   A massive rock buttress was constructed at the base of the slope because landslide deposits extend along essentially the entire mountain front.    The figures below show the  size and location of the buttress but because of the scale of the project it is difficult to fully comprehend it.   ADOT has an extensive photo gallery and history of the project online - 
https://www.flickr.com/photos/arizonadot/sets/72157649404759425/

 Excerpts from ADOT's announcement are below:


Two years after a landslide ripped apart a 500-foot section of US 89 and split the communities of Bitter Springs and Page, the Arizona Department of Transportation anticipates reopening the highway to traffic on the afternoon of Friday, March 27, barring any potential weather delays or mechanical breakdowns during the paving process, which began today.

Page Unified School District buses are expected to be the first vehicles to pass through newly rebuilt roadway. Students from the Bitter Springs and Marble Canyon areas have been among the most impacted by the US 89 closure, which has remained in place following the Feb. 20, 2013, geologic event approximately two miles north of the US 89/US 89A junction near the community of Bitter Springs.

Following the paving of Temporary US 89 in August 2013, US 89T has served as the detour route for motorists headed to and from the Page and Lake Powell areas, but residents and students in the Bitter Springs and Marble Canyon communities have still had to go out of their way to travel to and from Page and Lake Powell.

Prior to the March 27 reopening, crews will be completing the paving, install rumble strips and guardrail, and add temporary striping and pavement markers along the roadway.
Prior to launching the $25 million repair project last summer, which included removing approximately one million cubic yards of rock material to realign the roadway and construct a downslope rock buttress at the base of the Echo Cliffs to stabilize the area, ADOT had to clear several hurdles to move the project forward.

The ultimate repair of US 89 is the final step in fulfilling ADOT’s three-pronged approach to the US 89 landslide incident, which included providing immediate emergency access, conducting a geotechnical investigation and restoring essential traffic to the area. Paving US 89T (Navajo Route 20) has been the short-term solution for motorists driving to and from Page.

After an extensive geotechnical assessment identified the necessary repairs in July 2013, ADOT retained an engineering firm and developed plans for the eventual repair; finalized all federally required environmental reviews that included cultural, biological and water quality measures; and completed plans for the required right-of-way easements.

ADOT, along with the Federal Highway Administration, Navajo Nation, Navajo Division of Transportation and the Bureau of Indian Affairs, were able to expedite the environmental, utility and right-of-way clearance process, knowing that the use of US 89T was a temporary fix, especially for the Bitter Springs area communities.

The US 89 landslide repair project is eligible for reimbursement through the Federal Highway Administration’s emergency relief program, which provides funding to state and local agencies for the repair or reconstruction of highways, roads and bridges that are damaged in natural disasters and catastrophic failures.
