Vancouver, British Columbia - Cardero Resource Corp. ('Cardero' or the 'Company') (TSXV: CDU, Frankfurt: CR5) is pleased to announce that it has engaged Global Resource Engineering of Denver Colorado ('GRE') to complete a Preliminary Economic Assessment ('PEA') for the Company's Zonia Copper Oxide Project, located in Yavapai County, Arizona USA.
'We are pleased to move forward with the engineering process on the advanced Zonia project. We believe this PEA will provide us with confirmation of the viability of the project and gives us a road map that assists with the production of a Feasibility Study' says Stuart Ross CEO of the Company.
Zonia Copper Oxide Deposit
The Zonia Copper Oxide Project has been held under private ownership for almost 100 years and has undergone comprehensive exploration, metallurgical studies and mine development planning. The majority of the mineralized area was pre-stripped during previous open-pit mining operations at Zonia in 1966, as 17 million tons were mined with 7 million tons stacked on heap leach pads, producing cement copper up till 1975. The property has been drill tested with almost 700 drill holes (60,000 meters). This high-density drilling covers 30% of the property and defines the current resource estimate, reducing technical risk on the deposit.
The Zonia copper deposit has a north-easterly strike length of about 2,400 m (8,000 ft) and horizontal width varies from 60 m (200 ft) to 460m (1,500 ft). The deposit consists of multiple mineralized zones that dip at various angles to the northwest. The zones are generally in the order of 200 ft (60 m) wide and commonly occur in sub-parallel groups of three or more. Most of the deposit has been drilled to depths of 120 m (400 ft) or less. Deposit highlights include:
- Measured and Indicated Resources of 76.8 million short tons grading 0.33% copper containing 510 million pounds of copper (0.2% copper cut-off grade).
- Inferred Resources of 27.2 million short tons grading 0.28% copper containing 154.6 million pounds of copper (0.2% copper cut-off grade).
- Low strip ratio of 1:1 waste to mineralized material in base case.
Preliminary Economic Assessment
GRE will use the existing Zonia Copper Project resource estimate and historical metallurgical reports as the basis for the new NI 43-101 Technical Report.
Multi Scenario Analysis will be used to evaluate the project economic results using a range of total copper cut-off grades to determine the most economic option. This will include development or updating of pit optimization parameters for Lerchs Grossman or floating cone miner pit optimization, and review of the block model, mine topography, heap leach pad, waste dumps and SX-EW plant sites.
Preliminary pit and phase designs will be completed, which will form the basis for the resource statement and production schedule for the selected scenarios. The pit design will include layout of haul roads for ore and waste transport and will also include preliminary design and sizing of the waste rock dump(s).
GRE will review metallurgical test work and update the process design if needed. This will include a review of existing test work reports and evaluation of existing assumptions: acid consumption, recovery, crush size, and others. A metallurgical balance will be developed and the process flowsheet modified as required.
Preliminary ancillary facilities designs will also be updated as required, including the heap leach pad, size, location and configuration for optimum new resource tonnage.
GRE will create a preliminary water balance for the complete site, including water consumption by the heap leach and will update capital and operating costs (mine and plant) using Infomine Mine, and Mill Equipment costs and Mining cost models, as well as in-house expertise.

ABOUT CARDERO RESOURCE CORP.
Cardero Resource Corp., headquartered in Vancouver, is a resource company focussed on building a minerals exploration and development company. Cardero has the exclusive option to acquire up to a 100% interest in the Zonia Copper Oxide Project, located in Arizona. Zonia is a near-surface copper-oxide resource and a brownfields site having already been mined in the late 1960s and '70s.
The entire resource (NI 43-101 as amended and dated October, 2017), as currently defined, is located on private land and Cardero's plan going forward is to complete detailed engineering in anticipation of permitting the Project.
In September 2016, Cardero completed staking a total of 57 claims, the Silver Queen block, covering 424.5 hectares (1,049 acres) adjacent to the southeast edge of Zonia. The Company has plans for exploration work on the Silver Queen claims which will include geological mapping, soil sampling and geophysics.
The Company also has two option agreements covering five nickel-cobalt properties in south eastern British Columbia the, Kootenay Project totalling approximately 8,000 hectares. The Project is within the prospective Lardeau Group, which hosts numerous volcanogenic massive sulphide deposits, including the past-producing Goldstream mine located north of Revelstoke.
