The May episode of "Arizona Mining Review" is now posted on our YouTube channel at  http://youtu.be/TpAPvJ7E-Rs
Our guests included Joe Bardswich with Northern Vertex talking about the Moss gold mine,   Jerry Aiken and Matt Monte with Passport Potash on the status of their proposed Holbrook mine, and David Newlin about the community response to potash mining in the Holbrook area.
AZGS minerals chief Nyal Niemuth offered a brief update on mining news, and Kim Patten and Christy Caudill gave a demo of the National Geothermal Data System.

The State Geologists annual meeting got underway yesterday in Deadwood, South Dakota, with committee meetings and kickoff icebreaker. The formal program started this morning with a keynote from Elizabeth Eide, from the National Research Council.  She described the challenges of mission realities, quoting Mick Jagger, "you can't always get what you want, but if you try sometime, you just might findyou get what you need."

AZGS is holding the annual meeting of the State Geothermal Data project that we are managing, in conjunction with the AASG meeting, since 44 of the state surveys are project partners.   We have numerous presentations and breakout sessions spread through the next three days on completing the last year of the DOE-project and developing a sustainability plan following that.

ADOT has 8 videos posted on different aspects of the Bitter Springs landslide that closed US89 south of Page this winter.    The latest offers a status report and initial findings from the ongoing investigations.



Wayne Ranney's posted an excellent analysis of the situation at his Earthly Musings blog - 
http://earthly-musings.blogspot.com/2013/05/status-update-highway-89-slump-and-road.html

ADOT's contractors have found a shear zone between depths of 105 and 125 feet below the roadway, which puts it in the Chinle Formation, the clay rich unit that is the base of mega-landslides throughout the region.

Wayne raises the question of whether US89 can be rebuild across the giant landslides that cover the slope heading up through the "Big Cut" to Page.

ADOT is preparing to pave Navajo Route 20 (N20) as a detour at a cost of $28 million.     The question is whether the geotechnical investigations find that the challenges of rebuilding US89 can be overcome and if so, can the costs be justified.  If not, it would seem likely that N20 becomes the new primary corridor.

A magnitude 2.8 earthquake struck about 22 miles west of Page, Arizona at 6:32 a.m. local time this morning.  [Right, orange star marks epicenter.   Red line is an active fault. Credit, USGS]

We were in Pittsburgh last week, running live demos of the National Geothermal Data System at the annual meeting of the American Association of Petroleum Geologists which drew over 5,000 attendees.   [Right, AZGS geologist/geoinformatics specialist Christy Caudill and I pose just before the exhibit hall opens to attendees]

We had a steady stream of folks stop by to try out the test version of NGDS which now has over 17,000 data sets, over 5 million records, and a wide variety of data types that are relevant not only to geothermal exploration and development but are valuable resources for geologic investigations and other natural resources.    Data are coming from state geological surveys, universities, and labs in every state.  Our first Canadian data are now online and more international connections are in development.

The system currently serves over 1.25 million oil and gas and water wells and we expect that number to triple by year end.   The open source, online, distributed system also makes data interoperable, a breakthrough approach that is dramatically reducing the time needed to integrate data from different sources.

A national study of groundwater depletion since 1900 includes reviews of Alluvial Basins and the deep confined aquifer in Black Mesa Basin in Arizona.

The Alluvial Basins include 72 distinct basins in south-central Arizona, covering 212,000 square kilometers, filled with as much as 3,000 meters of unconsolidated alluvial fill.    The use of Colorado River water and recharge of basins, has halted or even reversed groundwater declines in some basins since 1980, but it appears that cumulative groundwater withdrawal as of 2008 was 102 cubic kilometers.


Groundwater withdrawal from the multiple zones in the Navajo ("N") aquifer in northeast Arizona has increased since the 1960s for municipal and industrial uses,  cumulatively totaling an estimated 0.22 cubic kilometers by 2008.

A new report from the USGS warns that on the high demand basis for nuclear power through 2035, the identified resources from operating and developing mines is inadequate.

In the report, Critical Analysis of World Uranium Resources, they found that "This analysis indicates that mine development is proceeding too slowly to fully meet requirements for an expanded nuclear power reactor fleet in the near future (to 2035), and unless adequate secondary or unconventional resources can be identified, imbalances in supply and demand may occur."   [Right, head frame of the Arizona #1 uranium mine, currently operating in northern Arizona.  Courtesy, Denison Mines]

"At 2010 rates of consumption, uranium resources identified in operating or developing mines would fuel the world nuclear fleet for about 30 years. However, projections currently predict an increase in uranium requirements tied to expansion of nuclear energy worldwide.  In the low demand case, uranium identified in existing and developing mines is adequate to supply requirements. However, whether or not these identified resources will be developed rapidly enough to provide an uninterrupted fuel supply to expanded nuclear facilities could not be determined."

 The presentations from the annual Peer Review of US DOE funded geothermal projects are now posted online.  AZGS presented the progress and results on the National Geothermal Data System we run on behalf of the Association of American State Geologists. NGDS is in a beta test mode, with over 17,000 data sets comprising more than 5 million records currently.  That number is expected to double or triple by year end.

The Geothermal Technologies Office funds 154 research and development projects leveraging nearly $500 million in total combined investment, and 95 of the those projects presented at the annual Peer Review event. Each project represents a growing technology sector in conventional hydrothermal, low-temperature and co-produced, or Enhanced Geothermal Systems (EGS) technologies, as well as technical and non-technical research and analysis.
Each year, DOE requires a rigorous review of investments by independent, qualified peers to assess key achievements in geothermal development and to meet strategic DOE guidelines. Peer Review offers geothermal stakeholders an opportunity to learn about the projects funded by DOE across a wide spectrum of technical complexity and funding magnitude, from research and development to demonstration and analysis. The event also opens a dialogue with other respected researchers in geophysics, geochemistry, modeling, tools, and more.
 
The U.S. Department of Energy (DOE)'s Geothermal Technologies Office Peer Review meeting was held on April 22-25,  in Denver, Colorado.

ASU's School of Sustainability is using a crowd-sourcing approach to map global carbon dioxide (CO2) emissions.  The research team "developed a website with a Google Earth interface that makes it easy for everyday people around the world to enter information. The website, “Ventus,” aims to create a complete list of global power plants, something that does not exist and is needed to fully comprehend the global carbon emissions cycle."

 The Utah Geological Survey has released a geologic map of the Glen Canyon Dam area of southern Utah and northern Arizona (provided as two plates-east and west parts), which is one of several maps recently completed by the Utah Geological Survey that provide complete geologic map coverage of Lake Powell and Glen Canyon National Recreation Area.

The announcement says "Glen Canyon Dam, completed in 1964, is anchored in Jurassic Navajo Sandstone, the oldest formation exposed in the map area. Jurassic and Cretaceous strata are cut by a few small faults and warped by broad shallow folds. Surficial deposits consist of extensive river and stream terrace gravel, eolian sand, and minor alluvium and talus. The map is based on new field mapping and aerial photograph interpretation and is provided as two plates in PDF format with a 12-page explanatory booklet that describes map units."

Arizona mining companies are having a hard time finding qualified candidates for even high paying jobs, and that's symptomatic of  the industry nationwide.  

SME and GSA are offering a webinar on "Emerging Workforce Trends in the U.S. Energy and Mining Industries" on Thursday, May 23.


Following is the announcement from the two professional societies:
Access to energy and mineral resources is essential to support the United States' high standard of living, economy, and security. The outlook is bright for U.S. energy and mining jobs as these industries should continue to grow and pay well, but the nation will have to overcome a looming retirement bubble and low number of prospective employees skilled in science, technology, engineering, and math (STEM).  Some innovative solutions are being pursued, but more action is needed if the nation is to maintain a skilled workforce able to supply its energy and mineral needs.  The National Research Council (NRC) report Emerging Workforce Trends in the Energy and Mining Industries:  A Call to Action examines the current and future workforce situation for the non-fuel mineral, oil and gas, coal, nuclear, geothermal, solar, wind, and carbon sequestration sectors and frames some steps the nation can take to help ensure it meets the country’s future needs in these industries.

Leigh Freeman and Jerry Ventre, professionals with the mining and solar industries, respectively, were members of the NRC committee that authored the report.  They’ll provide a brief synopsis of the report and take questions from the audience.

• LEIGH FREEMAN is the principal and general manager of Downing Teal, Inc. He has over 30 years of domestic and international experience in the resource industries.  Early in his career, Mr. Freeman served in technical, management, and executive positions with large and small resource companies.  He serves in leadership roles for the Society of Mining Engineers, Society of Economic Geologists, Industrial Minerals Association, International Center for Appropriate and Sustainable Technologies, as well as Montana Tech, South Dakota School of Mines, University of Arizona, and Queen’s University. Mr. Freeman received his B.S. in geological engineering from Montana Tech of the University of Montana.
  
  
  
• GERARD (“JERRY”) VENTRE is a consultant in photovoltaic (PV) systems engineering, specializing in workforce development, system design, and product assurance. He has over 35 years of experience in research, development, design, systems analysis, and education. For 20 of those years, he led the PV and distributed power programs at the Florida Solar Energy Center, a research institute of the University of Central Florida. During that time he also managed the U.S. DOE’s Photovoltaic Southeast Regional Experiment Station, with emphasis on test, evaluation, and application of PV and advanced technologies.  He received his B.S. degree in aerospace engineering, and his M.S. and Ph.D. degrees in aerospace engineering and applied mechanics from the University of Cincinnati.

Arizona made the front page of The Northern Miner last week, with headline stories on Passport Potash's program in the Holbrook basin, and the sale of BHP's Pinto Valley copper mine.

The weekly paper is one of the leading news sources for the mining industry.

The Arizona Dept. of Transportation says there is currently no timetable for reopening US 89 which was closed earlier this year because of a landslide near Bitter Springs, south of Page [photo credit, ADOT].   Instead, the unpaved Navajo Route 20 (N20) is going to be paved starting at the end of the month to offer an alternate route. ADOT expects it to be complete in late summer.  The paving project was projected to cost $28 million.   The Federal Highway Administration has approved $35 million for repairs to US89.

An ADOT announcement says:

• This schedule assumes that the necessary agreements which are currently pending are finalized and in place.
• Improvements to US 89T (N20) will pave the unpaved 27-mile segment of N20 and includes the installation of fencing, cattle passes, cattle guards, and signage. 
• ADOT will consider bus pullout opportunities adjacent to US 89T (N20).
• Commercial vehicle traffic (trucks) will be allowed on US 89T (N20) once paving is complete.
• Once the paving is completed, ADOT would designate the route as US 89T (N20) and would provide roadway maintenance services.  After repairs to US 89 are complete, US 89T (N20) will be relinquished to the Bureau of Indian Affairs.

US 89 Landslide Area

• Development of the Draft Final Geotechnical Report is anticipated to be complete at the end of May.  The Draft Final Report will provide recommendations for roadway repair.
• There is currently no timetable for reopening US 89, but ADOT is committed to restoring this important travel route as soon as safely possible.
• Strict security measures on US 89 are being enforced to ensure the safety of the crews and emergency vehicles.  This area is still considered unstable and is not safe for public travel. US 89 is closed to all traffic with the exception of authorized ADOT crews and emergency vehicles.  Additional security fencing and ongoing efforts to monitor the site are in place to prevent security breaches.
• In the event of an emergency, the public is encouraged to contact Navajo Emergency Services at 928.283.3111. 

Resolution Copper is facing a raft of challenges in its goal to develop one of the world's largest copper mines outside Superior, Arizona, but may go ahead with the project even if the controversial federal land exchange is not approved by Congress. 

 Parent company Rio Tinto cut the project budget substantially last year as part of a global belt-tightening and lack of progress in the land exchange the company wants to ensure the can go forward.   Resolution's other parent, BHP, just sold the Pinto Valley mine which had been the presumed site for the millsite and tailings.    Public support in the Superior area is waning as a result of these actions so Resolution staff are out on the road telling their story and answering questions.    Even so, polls show an 85% favorability in the greater Superior area.   [Right, head frame for shaft #10.  Credit, Nyal Niemuth, AZGS]

Vicky Peacey, senior manager of environmental and external affairs for Resolution provided an update to a crowd of about 150 yesterday in Tucson at the monthly Arizona Mining Alliance meeting.   She explained that regardless of the land ownership status the mine proposal would have to do National Environmental Policy Act (NEPA) studies on the full project and environmental impacts.  She also indicated the possibility that the project could go forward without the federal land exchange, although that is not their preferred route. Vicki noted that many mines are developed on federal lands but doing so would mean a large reduction in economic benefits to local and state governments.

The permitting process is expected to take the rest of the decade with first mining projected in 2020.   The company has invested about $1 billion so far, and expects to eventually spend $6 billion getting the project ready for production.   The mine should produce 1 billion pounds of copper per year making it one of the top 5 in the world.

The Arizona Corporation Commission says they have "ordered former Scottsdale resident John M. McNeil, California resident [and former Edmonton Oilers owner] Peter Pocklington and their affiliated companies to pay $5,149,316 in restitution and a $100,000 administrative penalty for committing securities fraud in connection with a gold mining venture" near Quartzite, Arizona.   The ACC announcement went on to say:

The Commission found that, while not registered as securities salesmen or dealers in Arizona, respondents McNeil, Pocklington and their affiliated companies— Crystal Pistol Resources, LLC, Crystal Pistol Management, LLC, and Liberty Bell Resources I,LLC — told at least 120 investors that they had obtained mineral rights to a placer mine outside of Quartzite, Arizona, and would begin mining and processing gold on the site within a short period of time. The Commission found that the respondents obtained at least some investors by making unsolicited telephone calls to them and that some investors were taken to the mine site, which was located on U.S. Bureau of Land Management land. Additionally, the Commission found that Crystal Pistol prepared newsletters in which it claimed to be offering one of the most lucrative dividend plans in the mining business and that hedge funds and banks were interested in the project. The Commission found, however, that the estimates of gold resources on the respondents’ website were not supportable with the methods currently available in the industry. In settling this matter, the respondents neither admitted nor denied the Commission’s findings, but agreed to the entry of the consent order. CBC News in Canada reports that Pocklington issued a news release saying that his "company has worked diligently and honestly with its investors and any errors were the result of inexperience and naivete, not malice or avarice, and were quickly rectified."

The situation of the Navajo Generating Station [right, credit NGDS], a coal-fired power plant in Page, Arizona is complex.    It is a major economic engine for the Navajo Nation, a major supplier of power for the Central Arizona Project, a target of the EPA for air quality, and the focus of debate on all those topics.   Alan Dulaney,  Water Policy Administrator for the City of Peoria, wrote a column in this month's issue of the Arizona Hydrological Society newsletter that brings some of these complex interactions into focus.  It is reprinted below with approval of Alan and AHS:
Navajo Generating Station hangs by a thread. So stated David Modeer, General Manager of the Central Arizona Water Conservation District (CAWCD), on May 1 in Glendale. And the fate of a major portion of the reasonably priced, replenishable water supply for central Arizona hangs with it. The Central Arizona Project has been a goal for Arizona since 1912. Arizona takes 1.5 million acre-feet each year off the Colorado River and moves it through Maricopa, Pinal, and Pima Counties. But a tremendous amount of power is needed to move that water uphill to Tucson. Navajo Generating Station (NGS) provides that power, and keeps CAP water rates reasonable. Without reasonable rates, farmers have made it clear that they will pump mostly groundwater again, and municipal users would soon follow. All the progress that has been made since the 1980 Groundwater Management Act in moving the three most populous counties to sustainable water supplies could be undone. And it all comes to a head with NGS, which is facing a myriad of challenges to its continued existence.NGS sits on Navajo Nation land. On Monday night, April 29, the Navajo Tribal Council discussed the proposed lease extension which would allow NGS to operate beyond 2019. They came up with a new lease (10 amendments), voted 20-1 to accept their version, and President Ben Shelly signed it. But Salt River Project, which operates NGS, has said it will not accept the changes. NGS takes 34,000 acre-feet each year of Upper Basin Colorado River water from the Navajo Nation allotment for cooling, leaving only 17,000 acre-feet for the Navajo Nation. The Navajos want all their water back. They also want more control over the plant, and want the US Bureau of Reclamation to sign the lease. SRP and the other partners believe promises of more money and jobs will prevail. SRP must continue negotiating with the Navajos - but a new lease is by no means certain. In my opinion, non-Reservation folks do not truly grasp what the Navajos want, which is control over their own natural resources and cultural traditions. This is not a situation that can be resolved with more money; both sides are operating under different assumptions. I am not hopeful that a new lease will be possible as long as the two sides talk past one another.Just a couple of weeks ago, Nevada Power suddenly announced that they would seek legislative permission to withdraw as a partner in NGS. We already knew that Los Angeles Power and Water was withdrawing, but the Nevada announcement came out of the blue. I suspect that continuing uncertainty with the lease - and beyond that, new coal contracts, EPA visibility rule requirements costing up to $1.1 billion in retrofits, and other challenges still unresolved - caused Nevada to decide that withdrawing would be the best option. Who will be next to bolt?Arizona has done more water planning than any other state in the Union. The CAP canal is proof of that. Because of our water resources expertise, we sometimes think that our structure of water rights and engineering is unshakeable. It has brought us years of sustainable water at reasonable prices. Yet as David Modeer noted, uncertainty rules CAP from here on out. Only one thing is certain: the era of cheap water is over.Alan Dulaney,City of Peoria
