Study: Rosemont Copper mine has lost $3 billion in value due to permitting delays

Arizona Geology Blog - Tue, 2015-07-28 19:42
Permitting delays have reduced the economic value of the proposed Rosemont copper mine by $3 billion according to a new study commissioned by the National Mining Association.

NMA commissioned  the  study "Permitting, Economic Value and Mining in the United States", "to demonstrate the economic impact of mining project permitting delays in the United States."   The study researched "selected mining projects at various stages of operations and permitting, in a number of states, to assess the delays that are associated with mine permitting."

The Rosemont copper project south of Tucson was one of the case studies analyzed for the study,   They concluded that "the Rosemont Copper project in Arizona continues in its attempts to secure permits, five years after the originally
planned start date of 2010. Over this period, the value of the project has fallen from $18 billion to $15 billion despite much higher copper prices."

The key findings are that :

  • Unexpected delays in the permitting process alone reduce a typical mining project’s value by more than one-third.
  • The higher costs and increased risk that often arise from a prolonged permitting process can cut the expected value of a mine in half before production even begins.
  • The combined impact of unexpected, and open-ended, delays and higher costs and risks can lead to mining projects becoming financially unviable.







The study found that permitting in the US takes 7-10 years compared to 2-3 years in Canada and Australia, countries with comparable environmental requirements.   I spoke with Katie Sweeney, General Counsel for NMA on our video magazine "Arizona Mining Review' and she said the solution is not to weaken environmental regulations but to require permitting agencies to coordinate their reviews and abide by deadlines.    There is also federal legislation being proposed to require agencies to complete their reviews within specific time-frames, comparable to those in other developed countries with stringent environmental standards.

Bomb threat empties state office complex

Arizona Geology Blog - Tue, 2015-07-28 13:50
A bomb threat to the Attorney General's office prompted evacuation this morning just after 10 am, of the State Office Complex in Tucson where AZGS is  housed.   Police just gave us clearance to return to our offices after 3 and a half hours.  They brought in bomb-sniffing dogs and a robot from the Tucson Police Bomb Squad [right, robot rolling off the ramp.  bottom, robot on its way to investigate backpack. Trucks in the street carried the canine units].

News reports say similar threats were called into the Attorney General's offices in Phoenix and Prescott.  The Tucson office was the last to be cleared because of a suspicious backpack found outside our building entrance that was situated such that if it was a bomb, would have been aimed at people leaving the main entrance.  The robot unit was sent in to investigate along with officers in body armor and blast gear.

From conversations with officers on the street, nothing was found., and we  were allowed to return about 1:30 pm.     For most employees, our vehicles were in the parking garage and not accessible.   After about 2 hours they brought in city buses so state employees could get in out of the heat which has been just under 100F.  A lot of folks headed to nearby stores and restaurants for an early lunch and cooler air.

How would Arizona handle a major earthquake in California?

Arizona Geology Blog - Sun, 2015-07-26 11:21
We recently got an inquiry referencing a blog post I did some time back about whether Californians might stream into Arizona looking for shelter and assistance if a major earthquake strikes that area.

We turned to our colleagues at the Arizona Division of Emergency Management and Mariano Gonzalez, Jr., State Plan Coordinator, provided this information about the State Emergency Response and Recovery Plan (SERRP) relative to earthquake evacuation from California to Arizona:
1.  The SERRP is an all-hazards plan.  It contains 15 Emergency Support Functions, and Logistical Support and Specific Incident Annexes.2.  Arizona is a member of the Emergency Management Assistance Compact, an agreement of mutual aide and support amongst the States.3.  State agencies have specific rules, laws, and authorities that may allow them to engage immediately in their subject matter area in support of other states' requests.  In this case, a state agency may ask for coordination support from the State Emergency Operations Center to supplement their response work, whether in-state or at the request of another state.4.  FEMA Region IX has constructed a Concept of Operations Document with Arizona to allow for immediate synchronization of efforts in a catastrophic situation affecting Arizona and/or other states in Region IX's area.
These elements allow for rapid support in the initial response, short-term and long-term recovery.
The recent I-10 bridge failure in California demonstrated #2 and #3 above, as ADOT and CALTRANS worked to coordinate traffic control, information flow to the public, and situation reports regarding safety of the rest of the road infrastructure along I-10.  Hats off to ADOT for keeping the Arizona State EOC fully informed of their support to CALTRANS, including the use of WEBEOC to inform all concerned in a real-time basis.
This background supports the answer to Evacuation of California as a result of a catastrophic earthquake.  Arizona would support California's request for evacuation support and reception.  It would be upon California to define and determine (and inform) Arizona how it would map and time the evacuation.  Both Arizona and California's transportation and emergency management agencies would be closely involved in developing this timeline and the support needed. This timeline would be incident specific, and could change on the fly.
It is important to note that California has not engaged with Arizona, to my knowledge, in the past regarding evacuation planning as a result of a catastrophic earthquake.  We would welcome the opportunity.As a final note, cursory research of after action reports and available academic research indicated to our office that residents in California affected by earthquakes in the last thirty years were unwilling to evacuate.  Instead, they chose to camp in available spaces (parks, shelters, etc.) nearby to wait to go back in and rebuild/repair.   
Mariano shared that ADEM would like to work with California to develop a Concept of Operations document to better coordinate and cooperate in the event of a big quake.

Renewed interest in oil and gas exploration in Mohave County

Arizona Geology Blog - Fri, 2015-07-24 08:15

The recent news that a geophysical contractor is carrying out seismic exploration in the Golden Valley area of Sacramento Valley in Mohave County [right, marked by red pin. Credit Googlemaps], reminds me that I blogged about Vanterra Energy's plans for that area back in 2009 - http://arizonageology.blogspot.com/2009/09/deep-oil-test-planned-near-kingman.html
 
Vanterra Energy which owns oil and gas leases in the area may have "farmed out" their acreage to another company that would earn an interest in the acreage by funding seismic and drilling a well to 12,000 ft.




My post in 2009 stated:



Forest Gate Energy announced today a partnership with Vanterra Energy and plans to drill a deep exploratory oil well in the Sacramento Valley of Arizona, southwest of Kingman.

The press release said, "Forest Gate and Vanterra are planning to drill an 11,000 foot well targeting the Navajo sands at 6000 feet, the Mississippian carbonates at 9,160 feet, and the Devonian carbonates at 10,160 feet.. A drill site has been selected using the results of a seismic program acquired by Phillips Petroleum in 1981 and subsequently licensed to Vanterra."

Forest Gate said they have run geochemical and geophysical surveys over the prospect. They compared the target as similar to the Grant Canyon oil field in Nevada [above, generalized geology of oil fields in Railroad Valley, NV, based on work done by Don French], which occurs in a block of Paleozoic sediments, down-dropped along a basin-bounding fault and perpendicular block faults.

Seismic exploration for oil and gas underway in Mohave County

Arizona Geology Blog - Thu, 2015-07-23 20:15


A seismic exploration company is carrying out a geophysical exploration program in Golden Valley in Mohave County to assess the potential for oil and gas deposits.    The company's  'thumper' trucks [right, credit Nodal Seismic] send vibrations into the ground which bounce off different geologic units and are recorded at the surface by seismic sensors.    The seismic signals provide a map of the shape and nature of rocks in the subsurface.
According to news reports, California based Nodal Seismic is collecting the seismic data for what I interpreted to be a 'spec' survey.  In other words they would not be "shooting" the seismic data (a historical term when dynamite was used to send the signals into the ground) for an oil company client but would collect it in order to sell it to petroleum companies to generate interest in the oil and gas potential of the area.    

Update 7-24-15, 8am: Since I wrote this, I understand Vanterra Energy may have an agreement with another company that would earn an interest in their leased acreage by funding the seismic acquisition and drilling of an exploratory well.
An article in the Kingman Daily Miner quoted residents as worrying about the impact of hydraulic fracturing or 'fracking' on their groundwater.   First, this is only a geophysical exploration program.  No one has proposed drilling any wells.  And even if wells were drilled, hydraulic fracturing is a technique that is used in only certain geologic environments.  We have not seen anything to suggest that geology in Golden Valley would be suitable for fracking.
The Arizona Oil & Gas Conservation Commission permits and regulates all oil and gas drilling and would specifically have to approve any hydraulic fracturing operations.
So, don't panic.   There are a lot of 'ifs' before any of this would lead to drilling or development.   There have been over 1,100 wells drilled for oil and gas in Arizona and only a handful ever produced and they are on the Navajo Reservation just on the border with Utah.

Sudden passing of Bill Dickinson

Arizona Geology Blog - Tue, 2015-07-21 07:34
We just learned from his family that William "Bill" Dickinson, Professor Emeritus in the Dept. of Geosciences at the University of Arizona, died in his sleep early yesterday morning while doing field work in Tonga.


His bio on Wikipedia notes that Bill was a member of the U.S. National Academy of Sciences. Prior joining the University of Arizona, Bill was a professor at Stanford University. He joined the UA faculty in 1979.

Dickinson is renowned for his work in plate tectonics, sedimentary geology and Pacific Oceana geology and is considered one of the foremost experts on the geology of the Colorado Plateau. Dickinson is one of the founders of the Gazzi-Dickinson Method and its primary application, QFL diagrams and their use in sandstone provenance.

Dickinson's research includes studying the potsherds (historic or prehistoric fragments of pottery) of Pacific Oceana. Over the years, he has visited hundreds of Pacific Islands collecting and dating sherds.

Only 10% of applicants get permits to visit famous "Wave" crossbedded sandstone site

Arizona Geology Blog - Sun, 2015-07-19 19:45
The Bureau of Land Management issues permits for only 20 visitors per day to visit the iconic Wave red sandstone crossbeds in the Paria Canyon - Coyote Buttes Special Management Area.   Only about 10% of the 73,000 annual applicants currently get permits.  BLM is seeking public comments on its proposal to increase fees and restructure the permit system.   [Right, photo credit Arizona Highways, Jeremy Jordan]

The area has become world famous in the past 20 years, attracting large numbers of foreign visitors on top of the growing popularity of the site among US hikers.


The Arizona [Flagstaff] Daily Sun reports that 
The changes suggested by BLM will transition all permitting in the area to an online system, including swapping a next-day walk-in lottery system for a 48-hour online one. Half of the 20 daily permits issued for Coyote Buttes South and North, where The Wave is located, are currently issued in the next-day lottery, which can attract more than 100 people per day... That same portion, 10 per day, will move to the 48-hour lottery, allowing people to better plan ahead for their trip.

The BLM’s draft plan also will raise fees, including an increase from $5 to $10 per person per night for overnight camping in Paria Canyon and an increase of the permit fee for Coyote Buttes North and South from $7 and $5 per person per day, respectively, to $12 per person per day. A $6 service fee would be charged by the online system for each permit issued.
 The St. George [Utah] Spectrum says the public is invited to provide feedback on the permit process and proposed fee increases, both of which are addressed in the Paria Canyon-Canyon Buttes Special Management Area Draft Business Plan, by August 17.

Comments may be submitted to BLM at  345 E. Riverside Drive, St. George, Utah, 84790-6714 or via email to blm_az_vcnm@blm.gov

Getting back on the grid

Arizona Geology Blog - Sun, 2015-07-19 19:25
We're back in Tucson and connected to the rest of the world online after a brief sojourn to the family cabin in northwest Wyoming.   My first time off in 14 months came after completing major deliverables for our two biggest funded projects due at the end of June.

The drive took us along the section of US89A rebuilt and recently reopened after a massive landslide took out a section of the road and rerouted traffic in and out of Page. ADOT engineered a huge buttress downslope to stabilize the megaslide area (right).

My blogging is way down the past year and more due to the press of so many projects but I have a good sized stack of items to write about.

Copper price plummets

Arizona Geology Blog - Sun, 2015-07-12 13:59


Copper has fallen 19 cents at the start of the past week, and was down 30 cents the past month.   The close on Wednesday  was $2.42/lb after briefly touching $2.40.  The price rallied back to $2.54 by week's end.  
Phoenix-based Freeport McMoRan Copper & Gold, the world's largest publicly traded copper producer saw their stock plummeted to $16.03 intraday.on Wednesday.
The price drop is not restricted to copper but is affecting all metals.  Arizona produces about two-thirds of the copper used in the US, so the price has a big impact on jobs and the economy.

Better management of wildfires in Arizona

Arizona Geology Blog - Fri, 2015-07-03 11:40

It's been a good year for fire management in Arizona, says AZGS geologist Dr. Ann Youberg. Ann is our resident expert on dealing with post-fire effects including debris flows, mudslides, and related hazards. She's often on the ground before the fires are out, working with state and federal forestry teams to assess the damage and potential for geologic hazards threatening people and property.

Ann says a lightning strike started a wildfire, the Camillo Fire, southeast of Mormon Lake on June 14th. [Right, Inciweb map of extent of Camilo fire. July 3, 2015] Because conditions were good within the forest, the Forest managed the fire for resources. This is now called Box and Burn. The Forest draws a box around the area within which the fire can continue to burn. These are low to moderate severity fires that are good for the ecosystem. The Fire Management team uses back burns to establish the exterior lines/boundaries and interior ignitions are used to get the fire to move into areas they particularly want burned within the box. This box was an astounding 46,000 acres. The Fire Management team released the final update; the fire “only” burned 23,866 acres. Although they didn’t get their whole box burned, having that much at low to moderate is awesome, to say the least. There were other Box and Burns around the state this June, due to the very nice weather we’ve had. Two were down in the Peloncillos, one is on the San Carlos Res, and another is on the Kaibab plateau.  There  may be others. All in all, a good fire year in Arizona so far.

Johnson Camp copper mine plans to resume operations, open 150 jobs

Arizona Geology Blog - Fri, 2015-07-03 11:27
News reports say that the bankrupt Johnson Camp copper mine in Dragoon, could be sold by the court receiver by mid-July to a Hong Kong based company and reopened after that.  [Right, view of pit. Credit, Nord Resources]

The Willcox Range News says once the assets are sold for $8.4 million to Mars Resources LLC free and clear of liens and claim, the operation will produce 150 new jobs, and the company expects another $5 million in spending for goods and services.

Nord Resources described the Johnson Camp Mine, as an open pit "copper mine and production facility located 65 miles east of Tucson, Arizona. The property consists of 59 patented lode mining claims (889 acres), 92 unpatented lode mining claims (1,494 acres) and 509 acres of fee simple lands totaling 2,892 acres. The on-site copper production facility includes a 4,600 gallon per minute solvent extraction plant and tank farm, a 52,000 lb/day capacity electrowinning plant with 74 cells, 8 million gallons of solution storage and other related equipment."

Governor appoints members to Oil & Gas Conservation Commission

Arizona Geology Blog - Fri, 2015-07-03 10:23
Gov. Doug Ducey reappointed four members and one new member to the Arizona Oil & Gas Conservation Commission.  This is the first time in a number of years that all the positions are filled.

The AZOGCC consists of five members appointed by the Governor and one ex-officio member, the State Land Commissioner. The Arizona Geological Survey (AZGS) provides administrative and staff support. Current Commission members include J. Dale Nations, Tucson, Chairman; Stephen R. Cooper, Casa Grande; William C. Feyerabend, Prescott Valley; Frank Thorwald, Sun City; Robert L. Wagner, Mesa; and Lisa Atkins, ex-officio member and State Land Commissioner.    

The Commission has no staff of its own, so the Arizona Geological Survey provides technical and administrative support to the Commission and carries out its decisions.

Jerome's Sliding Jail landslide is moving

Arizona Geology Blog - Sun, 2015-06-28 18:10
In the 1930s a landslide in the center of the city of Jerome is credited with moving the jail house hundreds of feet downslope.  In fact, the building was moved to get it on more stable ground.  But this spring, part of the landslide started moving again.    City officials have blocked off part of a parking lot where large cracks are continuing to grow. [Top, view to the northwest, with Sliding Jail in center background.  My photo.] ADOT is monitoring the movement because of the potential for impacts on US 89A.  Otherwise there does not seem to be much of a threat to property, in large part due to the city keeping development off the old landslide complex.

AZGS is working with city and ADOT officials to monitor and assess the movement.   [Bottom, view to the east.  The pipe carries away rain runoff to prevent it from running into the slide mass. My photo.]

"Arizona Mining Review" covers breccia pipe uranium, USGS mineral resource plans

Arizona Geology Blog - Sun, 2015-06-28 09:34
The June episode of Arizona Mining Review is now on YouTube at https://youtu.be/PGhJT945Ksw

The interview with Dr. Jon Spencer, Chief Geologist here at AZGS, about his new report on potential uranium-bearing breccia pipes in northwest Arizona is drawing a lot of attention.   He and his co-authors project one to two orders of magnitude greater numbers of collapse features, breccia pipes and corresponding mineral resources as currently known.

I also talk with former Pennsylvania State Geologist about USGS's revised  plans for mineral resource reports.  George led a panel discussion at the recent State Geologists Annual Meeting in Flagstaff, on mineral resources.

New report indicates massive increase in uranium potential in northwest Arizona

Arizona Geology Blog - Thu, 2015-06-25 09:10


We released our new report yesterday “Partial database for breccia pipes and collapse features on the Colorado Plateau, northwestern Arizona” (http://www.azgs.az.gov/news_releases2015.shtml#jun24) that found concentrations of breccia pipes 10 to 100 times higher than previously known, in two test study areas.  Breccia pipes are primary targets for uranium and other minerals.   We believe that same density of pipes extends across the entire region, which would make the area one of the largest and richest uranium districts in the world.  
I interviewed lead author Jon Spencer on our video magazine Arizona Mining Review which was webcast yesterday and is online at https://www.youtube.com/watch?v=PGhJT945Ksw.
We will be sharing this report with our congressional members to help them make informed decisions about the proposed Grand Canyon Watershed National Monument.
A 1989 USGS study mapped 1294 breccia pipes in the region.  Subsequent USGS maps and new investigations by AZGS identified at least 1,000 additional features in just two small study areas (outlined in red in map above).  It appears from this work that the number of likely breccia pipes is one to two orders of magnitude greater than previously recognized. The study raises the possibility that the higher concentration of breccia pipes extends across the entire region.


Mineralized breccia pipes—pipe-like masses of broken rock—may contain high-grade uranium ore and variable amounts of copper, gold, silver, vanadium and other mineral ore. More than 71 mineralized breccia pipes have been discovered in the region, and as of 2010, nine of these pipes yielded more than 10,500 metric tons of uranium.

Breccia pipes are vertical formations, typically a few tens to hundreds of feet across and hundreds to thousands of feet in vertical extent. The pipes formed more than 200 million years ago within Paleozoic and Triassic rocks over a broad area around Grand Canyon. The pipes formed as groundwater, flowing through Redwall Limestone dissolution breccias and along fracture zones, dissolved more limestone, causing collapse of overlying rocks and possibly creating sink holes.

This new map is accompanied by an Excel Workbook database with three datasets. The datasets are drawn from geologic maps produced by the U.S. Geological Survey and from mapping by geologic consultant and co-author Karen Wenrich. The datasets include point locations and comments on features identified as 1) breccia pipes, 2) collapse structures that might be breccia pipes, and 3) circular features that might be collapse features or breccia pipes.

Some features occur in more than one dataset, so the total number of features is less than the 3,286 features comprising the three datasets. GIS data as ArcGIS shapefiles built from the three datasets are included with this publication.

US Geological Survey geoscientists estimated that roughly 8% of breccia pipes contain some mineralization (Wenrich and Sutphin, 1988). A fraction of those are likely to host economic concentrations of minerals. 

In 2012, the U.S. Department of the Interior withdrew from mining 1,006,545 acres of federal lands in northern Arizona for a 20-year period to prevent further exploration or development of uranium on those lands. Withdrawal curtails new exploration of breccia pipes and limits production to those pipes with valid existing mineral rights.

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.
