The presentation also highlighted the extensive environmental studies that have been undertaken to design and operate the project in order to meet high environmental standards, as well as the environmental permitting, management and monitoring work that is ongoing to protect surface water and groundwater. Detailed reclamation plans and performance bonding (to ensure the safe and professional closure and reclamation of the mine upon completion of mining) is required before the project can be built.  These plans must be reviewed every three years by the Nevada Division of Environmental Protection.  The Yerington land conveyance, as directed by Congress, will also provide distinct opportunities to convert, rather than demolish, mine facilities such as buildings, power lines, water supply and wastewater treatment, and roads for other economic uses upon completion of mining.


Environmental Specialists Tim Leedy and Mark Hanley conduct groundwater sampling and monitoring seven days a week. Four people are presently employed at Pumpkin Hollow to manage the environmental aspects of the project including a network of 25 monitoring wells.  As the project transitions to production, additional management and monitoring will be conducted on air, water, mine rock, tailings and waste to insure that environmental resources are protected.

JULY 22, 2015 – 6 PM – Pioneer Crossing Convention Center


Please join us for a public information meeting to learn about the Pumpkin Hollow Project.

On Thursday, July 9, Nevada Copper Corp. published a revised feasibility study that describes an integrated open pit and underground mine with a 70,000 ton per day process plant. Combined with the passage of the Yerington Land Conveyance by Congress in December 2014, the company sees the opportunity to develop the Integrated Project (2 mines, one mill) instead of a smaller underground mine and mill first and then a second open pit mine and mill.  The Integrated Project greatly enhances the attractiveness of and opportunity to finance the bigger project.  At the same time we have nearly completed receipt of all necessary permits to develop the integrated project.

With all of this progress, we believe it is a good time to conduct a public information meeting to let the local community know all the things we are doing and will be doing.  This includes safety, environmental and reclamation programs, management and use of groundwater and surface water, construction, mining and processing operations, and the most frequently asked questions about jobs, training and hiring.

Our goal is to ensure our mine is the safest and most productive mine with minimal impact on the environment.  We intend to convert mine facilities to other future economic uses and reclaim mine rock and tailings storage areas, and restore natural vegetation ……  A responsible approach to mining. 

Before Nevada Copper begins production and makes its first penny from copper, it needs to invest $1 billion!

We first must:

  • Complete the land conveyance and state permitting
  • Secure financing for the project
  • Complete the main production shaft to 2,160 feet below the surface
  • Sink a second ventilation-emergency egress shaft
  • Develop the underground mine access drifts (or tunnels)
  • Construct processing facilities
  • Construct water, power and road access, as well as shops and offices
  • Recruit and train a workforce for mining and milling operations
  • Obtain and assemble mine shovels, excavators and haul trucks and other equipment for mining
  • Initiate underground and open pit mining

All of Nevada will benefit from the taxes and jobs created by the Pumpkin Hollow Mine Project. Over the period of active production, the Integrated Project would create approximately 900-1,000 direct jobs. In addition, the mine will employ contractors (indirect jobs) and create other “induced” jobs such as local retail or service businesses, teachers and other public services. Total direct, indirect and induced jobs created by this project are estimated to be 3,000-3,500.

We at Nevada Copper, Pumpkin Hollow Project are committed to an on-going consultation with the Yerington community and to provide updated information on the progress of our project as it moves along.

“Right Place. Right Time. Right People. Right Way.”

Nevada Copper Pumpkin Hollow Project Update

April 23, 2015 – Nevada Copper Corp. (TSX: NCU) (“Nevada Copper” or the “Company”) is pleased to announce results for an initial three diamond drill holes from the current open pit drilling program and to provide a project update at the Company’s 100 percent owned Pumpkin Hollow project located near Yerington Nevada.


  • Initial three drill holes yield strong results from new open pit drill program with particularly pleasing results from two new drill holes in the saddle zone between the North and South pits;
  • Underground drill program from 1,900 foot level to commence in May;
  • New integrated feasibility study results scheduled for release before the end of May;
  • Progress on federal land acquisition progressing according to plan with permitting progressing concurrent with land acquisition; and
  • MOU signed with large international steel company to assess opportunities to exploit Pumpkin Hollow’s significant iron ore resource.

Open Pit Drilling Results
Targeted drilling continues on the open pit deposit with the goals of testing the ultimate extent of the deposits, and identifying areas that may have economic copper mineralization but are currently categorized as waste due to lack of drill data.

The drill program which started in late February currently has three drill rigs on site. The current drill program will consist up to 74,000 feet (22,600 meters) of drilling. The first drill holes were drilled in the North Deposit to follow up open prospective areas identified in early 2013 drilling. Drill hole NC15-02 was drilled along the edge of the South deposit where mineralization was open. The table below summarizes the drilling results received for drill holes NC13-10; NC-15-01 and NC15-02. Assays for the remaining drill holes will be posted as results are received.

Greg French, Vice President of Project Development & Exploration, commented, “The current drill program is focused on the saddle zone mineralization located between the North and South pits and the open and inferred mineralized areas on the edges of the open pit deposits. The initial drill holes reported continue to expand mineralization. NC15-02 drilled along the southern portion of the South Deposit, discovered at shallow depths, a 125.5 meter zone averaging 0.42% copper. Mineralization remains open and the drill hole location in the current pit design is expected to upgrade currently classified waste material in that area.”

Drill hole NC13-10 was drilled in the Saddle Zone between the North and South open pit deposits. The mineralization correlates well with adjacent holes and bottomed in mineralization. This hole finished up a pre-collared hole from the previous 2013 drilling. The lower zone of intersected 62.4 meters (204.8 feet) true thickness averaging 0.27% copper and continues to push mineralization out and should convert mineral classification.

Drill hole NC15-01 also drilled in the Saddle Zone between the North and South deposits intersected two thick mineralized zones that correlate with adjacent holes but with slightly lower grade. The largest zone intersected 103.7 meters (340.3 feet) true thickness averaging 0.23% copper. There are also localized zones of high grade within low grade. The hole expanded mineralization within the present designed pit.

Drill hole NC15-02: South Deposit, intersected several zones of shallow mineralization along the southern edge of the deposit. The upper zones have expanded the existing mineralization. The lower zone 125.5 meters (411.7 feet @ 0.42% Cu), 88.7 meters (291feet) true thickness, is new, as several adjacent holes were only drilled as shallow pre-collars. Drill hole NC15-02 has expanded the mineralization. Follow up drilling for this expanded area and newly discovered mineralization is planned.

Underground Drill Program
Underground drilling of the East deposit is expected to commence in May 2015 from drill stations on the 1,900 foot level. The underground drilling program will consist of up to 26,000 feet (7,900 meters) of delineation and development drilling which will focus on further enhancing the high grade zones within the current mineral reserve, especially in areas planned for mining in the early years. This drilling program will also provide additional data for mine development designs while expanding the open mineralized areas.

Management believes that the program has the potential to improve the overall copper production grades especially in the early years while also allowing for expansion of the combined Eastern underground copper reserve boundaries that remains open in several directions.

Integrated Feasibility Study
Significant progress has been made on the Integrated Feasibility Study (“IFS”) with results targeted for release on or before May 28, 2015. The IFS envisages a single, large 70,000 tons/day concentrator with dual sources of mill feed comprising an average of 63,500 tons/day of open pit ore blended with 6,500 tons/day of high grade ore from the Eastern underground deposits. The IFS will incorporate all available current information, including approximately 32,500 feet (9,900 meters) of new drilling data from 2012 and 2013, mine plans, engineering work and updated capital and operating costs for both the open pit and underground operations associated with this development.

Federal Land Acquisition and Permits
Since passage in December of Congressional legislation that authorizes the transfer of federal lands to City and private ownership, Nevada Copper has been fully engaged with the Bureau of Land Management (“BLM”) and the City of Yerington to complete the land conveyance. The necessary agreements between the BLM and the City of Yerington are now in place to allow for the many activities to proceed toward the purchase of approximately 10,400 acres of land under the legislation. These activities include surveying, land valuation, and including compliance of the acquisition with provisions of the National Historic Preservation Act and National Environmental Policy Act. Nevada Copper and its consultants are working closely with the BLM and supplying additional resources to them as necessary to expedite the sale process.

Upon closing of the land conveyance, the City will convey 6,430 acres of private land to Nevada Copper. Adding this acreage to the 1,560 acres of private land that Nevada Copper currently controls, means that the Company will have a total of 7,990 acres (12.8 square miles) available for the large scale integrated open pit and underground mine development.

Permitting of the large open pit and underground integrated project is continuing according to plan. This permitting involves modification of our existing State air pollution control and reclamation permits to allow for the larger open pit operation and a 70,000 tons/day concentrator. Permitting is scheduled to be completed by mid-2015 concurrently with closing of the land acquisition.

Iron Concentrate Study
The Company recently executed a Memorandum of Understanding (“MOU”) with a large multi-national steel producer to assess opportunities to exploit the large Pumpkin Hollow iron resource. Measured and indicated iron mineral resources total 395 million tons grading 32.1% iron using a 20% cutoff, as disclosed in a 43-101 Technical Report filed on SEDAR in 2013. The assessments would include drill sampling, mine planning, engineering studies and metallurgical work. These studies will determine if a byproduct magnetite (iron oxide) stream from the copper tailings at a future Pumpkin Hollow concentrator would be suitable as feed for downstream iron ore processing for use in steelmaking. Other work would focus how mining plans could be modified to deliver additional magnetite in the copper concentrator feed while minimizing loss of copper. Magnetite recovery circuits are not uncommon at copper operations which contain magnetite in their mill feed. Examples are the Candelaria IOCG mine in Chile and Glencore’s Earnest Henry mine in Australia.

Along with low cost power, Pumpkin Hollow has close proximity to rail infrastructure which is important for moving the larger tonnages associated with any future iron ore production. The possibility of adding iron revenues at minimal or no cost has not been factored into any previous feasibility studies, nor in the current IFS to be released in May.

Workforce Information Update 2015



CatHaulNevada Copper has received a number of job inquiries recently at the Pumpkin Hollow Project.  However, hiring of a construction or operations workforce is many months out, since mine financing must be secured before further construction can be undertaken.

The passage of the National Defense Authorization Act of 2014 by Congress that included Yerington Land Conveyance and the $200 million financing were exciting milestones and put us in a strong position to continue development of the project.  The Company is re-evaluating the project development strategy based on an exploration program and project studies currently underway.

The Company has constructed a 24-foot diameter, 1,900-foot deep, production-sized shaft and 600 feet of lateral development (authorization mine “tunnels”).  This work was performed by Cementation, USA, a specialized shaft-sinking contractor.  During this phase of the project, a workforce of about 30-50 people were employed.

Completion of the land conveyance in October 2015 now affords Nevada Copper an opportunity to design and develop the project in the most cost effective manner.  The project is now located entirely on private land,  is fully permitted and “shovel-ready” for development. The company continues to work on planning and engineering design.  Once the necessary financing is secured and detailed design studies have been completed, development of the project and construction could be initiated and operations would follow several years later.

At this time we cannot accurately forecast the times when these different activities will occur.  Persons interested in employment opportunities or job training should monitor our website and social media site on Facebook for information on start-up of construction and operations:




  • Mining engineers
  • Metallurgical engineers
  • Electrical engineers
  • Civil engineers
  • Mechanical engineers
  • Structural engineers
  • Environmental engineers
  • Geologists
  • Hydrologists
  • Accountants
  • Supply chain professionals
  • Underground miners
  • Surface miners
  • Equipment operators
  • Supervisors
  • Electricians
  • Mechanics
  • Hoist operators
  • Safety professionals
  • Environmental technicians
  • Information systems and technology specialists

In the future, after Nevada Copper has obtained financing and would be able to begin construction, prospective job applicants will be asked to register with Nevada JobConnect. That information will be provided on this website at that time.

In the event that the Pumpkin Hollow Project starts operations, the company anticipates directly employing 750-800 people at the mine for a period of approximately 18 years.  In addition there will be approximately 100-500 people employed during various stages of construction. Based on the 2.5 job multiplier (Nevada Mining Employment Impacts 2014 (Page 123)) direct,  indirect and induced employment created by Pumpkin Hollow could be approximately 2,500.  Historically, mining jobs are among the highest-paying positions in Nevada. Nevada Mining Association reports that the average miner in Nevada earns $91,936 per year (Nevada Mining Industry Average Wages, page 114).

The Pumpkin Hollow project is still in the planning stages, so please check this website periodically to monitor project development and possible future employment.
