VANCOUVER, June 16, 2015 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces a new Preliminary Economic Assessment (PEA) and a mineral resource update incorporating all drill results through 2014 from the newly discovered YellowJacket high-grade gold deposit (Table 1 and 2) at its North Bullfrog project.  The PEA results have outlined a potential, high margin, oxide mining project with low development/capital cost projections (Figure 1 and 2) in the current gold price environment.

Jeff Pontius Corvus Gold CEO states… "The results from this initial analysis of the North Bullfrog deposits have clearly illustrated the economic potential of this new and emerging Nevada Gold District.  The unique mix of a high-grade vein/stockwork deposit surrounded by oxide heap leach deposit has resulted in a potentially exceptional, low strip, open pit, mining project in one of the best jurisdictions in the world.  By using a conservative US$900 gold price driven Whittle^TM pit to define the PEA base case pit design the project demonstrates potential to perform well in the current gold price environment.  The existing project infrastructure and advanced permitting work linked with simple oxide processing offers the opportunity for a low Capex, high margin operation with near term production potential. Utilizing the new high-grade YellowJacket deposit as our proof of concept, we have begun a District wide exploration and development program to identify other large vein systems as well as follow-up resource expansion drilling of the YellowJacket deposit, both of which could add significant potential to the North Bullfrog project and Corvus as a whole."

The PEA is based on the North Bullfrog resource model (as at June 16, 2015) which consists of material in the measured, indicated and inferred classifications.  Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the PEA will be realized.

PEA Results

The PEA assumes development of a conventional drill and blast, surface mine using haul trucks and front end loaders, milling of higher grade mineralization with gravity-cyanide leaching, of the YellowJacket mineral resource, and heap leach processing of low grade mineralized material from the Sierra Blanca, Jolly Jane, and Mayflower mineral resources .  Mineralized material from the YellowJacket vein and stockwork mineral resource would be delivered to a processing plant incorporating a gravity concentration circuit with intense cyanide leaching of the gravity concentrate followed by cyanide leaching of the gravity tail product. Tail materials would be stored in a conventional, lined tailing storage facility (TSF). Lower grade disseminated mineralization would be processed by heap leaching of run of mine (ROM) material. Ultra-high intensity blasting would be performed to minimize particle size for enhanced heap leach recoveries and would allow transport and stacking on a heap leach pad using a feeder/conveyor/stacker system.  Gold and Silver in leachate solutions would be recovered from carbon from both process plants and a doré would be produced in a refinery located in the Mill.  Sensitivity of the projected financial performance of the North Bullfrog project is listed around the Base Case assumption of a constant gold price of US $1,200 per ounce in Table 2.

The PEA uses gold and silver recoveries for a gravity-cyanide leach mill that are estimated from two sets of metallurgical composite samples developed from PQ core materials generated in YellowJacket drilling programs during 2013 and 2014. Gravity concentrate samples were developed using a Knelson^TM concentrator. The Knelson^TM feed was ground to P80 -0.21mm (-65 mesh). The produced gravity concentrate was then re-ground to P80 -0.044mm (-325 mesh), and subjected to intense cyanide leaching. The leached concentrate was then re-combined with the gravity tail product and ground to P80 -0.074mm (-200 mesh) before the final cyanide leach to maximize gold and silver recovery. Average recoveries of 86.8% for gold and 71.4% for silver were assumed for the mill process plant.

Heap leach metallurgical recovery estimates are based on column leach testing data for composite samples constructed from Mayflower, Jolly Jane, and Sierra Blanca 2012 PQ core drilling. A total of 23 column leach tests have been run at McClelland Laboratories at a particle size of 80% passing -19 mm (-3/4 inch) for the four resource areas. The process recovery assumptions reflect consideration of particle size resulting from ultra-high intensity blasting with a particle size of P80 -84mm (-3.3 inch), similar to a primary crushing product, scaling for the effects of vertical lift heights of > 10m (30 ft) and a leach time of 1000 days. The leach pad production model predicts an average gold recovery of 74%, and an average silver recovery of 6% of the fire assay grade.

A summary of the PEA results for the base case gold price assumption of US $1,200 is listed in Table 3. Working capital and initial fills, which are recovered at the end of year 1 and at the end of the project respectively, were estimated to be US $16.4 M.  Operating costs included in the PEA were based on mining, processing, administration and reclamation, and are listed in Table 4, where they are normalized to process tonnage and recovered gold ounces.  Total LOM cash operating costs are projected to be US $635 / produced Au oz and LOM capital cost (adjusted for recovery of pre-strip mining, working capital recovery and initial fills recovery) was estimated to be an additional US $206 / produced Au oz.

The Company cautions that the PEA is preliminary in nature, and is based on technical and economic assumptions which will be further evaluated in more advanced studies.  The PEA is based on the North Bullfrog resource model (as at June 16, 2015) which consists of material in the measured, indicated and inferred classifications.  Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.  The current basis of project information is not sufficient to convert the mineral resources to mineral reserves, and mineral resources that are not mineral reserves do not have demonstrated economic viability.  Accordingly, there can be no certainty that the results estimated in this PEA will be realized.  The PEA results are only intended as an initial, first-pass review of the potential project economics based on preliminary information.

Scheduled resource and mining geometries for the PEA were defined by Lerch Grossman optimization using a US $900 gold price, current prevailing mining costs, and the latest metallurgical data for the project.

Cash Flow Model Inputs and Assumptions

Mineral Resources - The analysis included measured, indicated and inferred mineral resources in the mining and economic study.  Measured and indicated mineral resources make up 91% of the mill gold production plan and 17% of the heap leach production plan with the remainder being inferred mineral resource.  

Project Schedule- The project schedule assumed a one (1) year period for construction of the mine infrastructure, and the initiation of mining at the YellowJacket and Sierra Blanca mineral resources. Mining was assumed to start at Mayflower in year 4 and at Jolly Jane in year 7.  Production from the four mineral resources was blended to level the required number of haul trucks with a peak mining rate of 89,300 tonnes per day.

Mining Method - A standard surface mine using a drill, blast, load, and haul mining plan was used for the study, assuming a 50 degree pit slope.  The mine volume was defined by Lerchs-Grossman optimization methods and the resulting mining volumes were used to develop a production plan that would be robust in a declining price market. Heap leach mineralization was assumed to be blasting using new, ultra-high intensity blasting to improve fragmentation for higher ROM leach recoveries without crushing. Within the mining shapes indicated by the Whittle^TM analyses, a processing cut-off grade of 0.1 g/t gold was used for selection of mineralized material to be sent to the heap leach processing facility and 0.372 g/t for mineralized material to be sent to the mill processing facility.  Conceptual locations for the crusher, heap leach feeder/conveyor, and overburden dumps were used to estimate truck haulage cycles, and the production schedule was constrained by the truck fleet capacity.

Processing Methods - A conceptual heap leach model was developed for the northern area of North Bullfrog to be operated at a peak placement rate of 58,000 tonnes (average rate of 44,400 tonnes) of mineralized material per day, with all material assumed to be blasted to 80% - 84mm (-3.3 inch), and transported and placed by a conveyor/stacker system. The higher grade, YellowJacket vein and stockwork mineralization was assumed to be crushed and milled at a rate of 3,000 tonnes/day with a final grind size of 80% -0.074mm (-200 mesh). Gold would be recovered by intense cyanide leaching of a gravity concentrate and a final cyanide leaching of tail products. Both of these processing approaches are supported by metallurgical test data.

Gold Recovery Model - Mill process recoveries were estimated from metallurgical testing of gravity concentration, intense cyanide leaching of the gravity concentrate, and final cyanide leaching of the tail products. A total of six different sample composites were created from PQ core developed in 2013 and 2014 drilling programs, and were tested to characterize the variation of vein and vein stockwork materials. Heap leach process recoveries were estimated based on the results of column leach testing of composite samples created from the 2012 PQ core metallurgical drilling program.  A total of 23 sample composites from the 3 current resource areas were prepared from 2012 PQ core and used to create duplicate column tests at a nominal crushed size of 80% -19 mm (-3/4 inch).  The column leach test data was used with recovery models that simulated the ROM particle size gradation, the effects of time for 1000 days leaching and leach pad loading geometry to project the produced gold and silver. The recovery model predicted LOM average gold recovery to be 74% of contained gold content and 6% of contained silver content.

Operating and Capital Cost Estimates - Preliminary capital and operating costs were developed using information available from other Nevada milling and heap leach operations, a commercially available mining and development cost database, plus all available project technical data and metallurgical/process related test work.  Detailed design work, used to assess the potential for a smaller scale start up mine, has been used to refine the capital cost estimate.  Preliminary configurations of the site infrastructure alternatives (mill, heap leach pad, tailing storage facility, overburden storage facility, roads, shops, offices, etc.) have been evaluated and an arrangement was defined as the basis of capital cost estimates.  Capital costs were developed based on a nominal mining rate of 44,400 tonnes of mineralized material per day. Total processed material would be 163.7 M tonnes.  Major mobile equipment was assumed to be financed over the first five years of life.  All costs are in constant US$ from Q2 2015. No escalation was applied in the financial model.

Taxes and Royalties - Taxes and royalty charges were included in this PEA.  Taxes included the Nevada Mineral Net Profit tax at the maximum rate of 5% of cash flow net of operating costs, depletion and depreciation of capital costs. US Federal taxes were 26% of cash flow net of operating costs, depletion and depreciation of capital costs. Net smelter return (NSR) royalties apply to about 15% of the projected gold production with a 4% NSR on the Mayflower production and a 1-4% NSR on a portion of the Jolly Jane production (the Company has buy-out rights on all royalties).

Revenue - Revenue was determined in the base case financial model assuming a constant US $1,200 per gold ounce gold price. All sensitivities to gold price assumptions were assessed using constant US$ prices.

New Resource Calculation

The new mineral resource calculation reflects the benefits of the detailed 2014 infill drilling program leading to better defined vein/stockwork zone (Table 6 & 7).  The high average grade of the YellowJacket deposits along with its simple, oxide, high gold silver recoveries and open pit mining potential has produced an attractive near-term mining target.  In addition the new mineral resource has been calculated at a lower base case resource price of US $1,200 (April 1, 2014 resource used US $1,300 gold price), which has produced a more robust project.  The insight gained from the new detailed drilling of YellowJacket has been instrumental in defining and prioritizing Corvus' 2015 new discovery high-grade vein system exploration targets where drilling will begin this month.

****-The Mineral Resources above are effective as of June 16, 2015.
*****-Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

The Resource estimation is based on 280 drill holes with 41,314 gold composites. Geologic volumes were defined and used to constrain the estimation. Heap leach resources were estimated by regular Kriging. The YellowJacket vein and stockwork were estimated using Inverse Distance Cubed calculations.  To define the reasonable prospect of economic extraction, Metal Mining Consultants Inc. confined the resources to mining volumes defined by Whittle ^TM analysis. There are no known legal, political or environmental risks that could materially affect the potential development of the mineral resources.

YellowJacket High-Grade Resource

The YellowJacket mineral resource area is immediately east of the Sierra Blanca deposit and was modeled as a specific zone within the greater Sierra Blanca open pit deposit.  The zone has a North-Northwest trend and is currently defined by the Josh Vein on the west and the Liberator Fault on the east. This zone includes vein and stockwork vein type mineralization which remains open along strike and at depth.  In addition the 2014 drilling found several parallel, splay veins to the main Josh Vein which needs further drilling to assess their potential to expand the YellowJacket deposit.  Follow-up resource expansion drilling on the YellowJacket deposit is scheduled to follow the first two phases of District "new discovery" exploration drilling. 

Exploration Implications of the New YellowJacket Model

The new YellowJacket mineral resource model and its exceptional continuity and structural association is an important "proof of concept" for the occurrence of other large, high-grade, vein systems in the North Bullfrog project area.  This new detailed understanding of the deposit has formed the basis for an expanded new discovery exploration initiative in the District which started in May of this year.   One of the fundamental understandings gained for the 2014 infill drilling of the YellowJacket has been the timing and orientation of structural activity that created openings for high-grade vein/stockwork formation.  This knowledge linked with new property wide, detailed mapping, and age dating information has outlined a number of similar settings to the YellowJacket deposit which hold promise for other future high-grade discoveries.  Corvus' 2015 District–wide exploration drilling program is focused on testing up to 10, new high priority, high-grade vein targets this year in its effort to discover a new Bullfrog or YellowJacket type deposit.      

Mineral Resource Modeling Results

The North Bullfrog district-wide mineralization inventory includes four deposit areas, YellowJacket, Sierra Blanca, Jolly Jane, and Mayflower (Figure 1).  Mineralization occurs in two primary forms: (1) broad stratabound bulk-tonnage gold zones such as the Sierra Blanca, Mayflower, and Jolly Jane systems; and (2) moderately thick zones of high-grade gold and silver mineralization hosted by vein and stockwork vein zones dominantly at the YellowJacket deposit.

The structurally controlled vein and stockwork mineralization in the YellowJacket Deposit was modelled separately to prevent smearing of high-grade mineralization into the surrounding blocks. Based on the metallurgical data on YellowJacket mineralization, it has been assumed that this material will be processed through a separate milling circuit and thus carries different processing costs and recoveries, resulting in cut-off grades different than the heap leach processing.  These additional costs and recoveries have been accounted for in the Whittle^TM pit analysis.

The disseminated mineralization at Sierra Blanca was also modeled in a series of discrete volumes to prevent grade smearing across certain important grade-controlling faults. The disseminated oxide mineralization has been modeled based on our current metallurgy for run of mine heap leach processing with each resource area having an estimated heap leach recovery.  The heap leach feed then carries the costs associated with heap leach processing as reflected by the cut-off grade.   

The Company will file an updated National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") technical report (the "Report") to be prepared by independent qualified persons, which will include the results of the mineral resource update and PEA discussed herein, on SEDAR within 45 days, and investors are urged to review the Report in its entirety.

Cautionary Note to US Investors

NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  Unless otherwise indicated, all resource estimates contained in or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Standards on Mineral Resource and Mineral Reserves, adopted by the CIM Council on November 14, 2004 (the "CIM Standards") as they may be amended from time to time by the CIM.

United States investors are cautioned that the requirements and terminology of NI 43-101 and the CIM Standards differ significantly from the requirements and terminology of the SEC set forth in the SEC's Industry Guide 7 ("SEC Industry Guide 7").  Accordingly, the Company's disclosures regarding mineralization may not be comparable to similar information disclosed by companies subject to SEC Industry Guide 7.  Without limiting the foregoing, while the terms "mineral resources", "inferred mineral resources", "indicated mineral resources" and "measured mineral resources" are recognized and required by NI 43-101 and the CIM Standards, they are not recognized by the SEC and are not permitted to be used in documents filed with the SEC by companies subject to SEC Industry Guide 7.  Mineral resources which are not mineral reserves do not have demonstrated economic viability, and US investors are cautioned not to assume that all or any part of a mineral resource will ever be converted into reserves.  Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically.  It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility study, except in rare cases.  The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit amounts.  The term "contained ounces" is not permitted under the rules of SEC Industry Guide 7.  In addition, the NI 43-101 and CIM Standards definition of a "reserve" differs from the definition in SEC Industry Guide 7.  In SEC Industry Guide 7, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made, and a "final" or "bankable" feasibility study is required to report reserves, the three-year historical price is used in any reserve or cash flow analysis of designated reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. The mine economics presented herein and derived from the PEA are preliminary in nature and may not be realized. The PEA is not a feasibility study. U.S. investors are urged to consider closely the disclosure in our latest reports and registration statements filed with the SEC. You can review and obtain copies of these filings at http://www.sec.gov/edgar.shtml. U.S. Investors are cautioned not to assume that any defined resource will ever be converted into SEC Industry Guide 7 compliant reserves.

This press release is not, and is not to be construed in any way as, an offer to buy or sell securities in the United States.
