TSXV: NEV
VANCOUVER, Nov. 5, 2015 /CNW/ - Nevada Sunrise Gold Corporation ("Nevada Sunrise" or the "Company") (TSXV: NEV) is pleased to announce that Pilot Gold Inc. ("Pilot Gold") (TSX: PLG) has reported the first independent resource estimate for the Kinsley Mountain Gold Project ("Kinsley Mountain", or the "Property") in eastern Nevada.
The resource estimate defines a significant high-grade zone at the Western Flank along with near-surface oxide ounces. Gold mineralization at Kinsley Mountain hosts sedimentary rock-hosted, similar to that mined in Nevada's Carlin and Cortez trends. The potential for resource expansion is excellent due to widespread alteration, prospective geology and gold at surface, and over 80% of the Property is untested by drilling. All dollar amounts quoted in this news release are in US dollars.
The resource estimate for all mineralization types, using multiple cut-offs, is:

"This initial resource estimate validates the exceptional work completed by the Kinsley Mountain joint venture, and the quality of Pilot Gold's operatorship at the Project over the last four years," said Warren Stanyer, President and CEO of Nevada Sunrise. "We believe this landmark resource represents the beginning of a new era for Kinsley Mountain, and the results of the work to date demonstrate the strong potential for discovery of additional gold mineralization."
Mineralization hosted in the Secret Canyon Shale in the Western Flank zone includes 284,000 Indicated ounces at an average grade of 6.04 g/t gold. At a 3.0 g/t cut-off grade, most of the resource remains, delineating 248,000 Indicated ounces at an average grade of 9.15 g/t gold (see Sensitivity Table below). The grade improves 51%, while the gold content is only reduced by 13%. Metallurgical testing of mineralized material from this zone suggests that it is amenable to production of a flotation concentrate with grades up to 312 g/t gold and recovery of up to 95% using a flowsheet including cyanidation of the tails (see Nevada Sunrise news releases dated January 19, 2015 and July 13, 2015). The metallurgical response indicated by testing to date allows for consideration of lower cut-off grades than might ordinarily be used in modeling Carlin-type sulphide material.

The resource estimate, effective October 15, 2015, includes three separate cut-off grades, reflecting depth from surface, oxidation, and metallurgical considerations. These include shallow oxidized rock (0.2 g/t Au cut-off); shallow transitional and sulphide mineralization, primarily hosted in the Dunderberg Shale (1.3 g/t Au cut-off), and Secret Canyon Shale-hosted sulphide and transitional mineralization (1.0 g/t Au cut-off). Cut-off grades assume an open-pit mining scenario, using a pit floor elevation generated using Whittle software, reasonable assumptions for mining and milling costs, and a $1,300/ounce gold price.
Resource Estimate
The Kinsley Mountain resource estimate was completed by Michael Gustin, Ph.D, CPG, of Mine Development Associates, Inc. ("MDA") of Reno, Nevada, an Independent Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. Estimation methods are summarized below. Further details of the estimation methods and procedures will be available in a NI 43-101 technical report, to be co-authored and released by MDA, which will be filed on SEDAR (www.sedar.com) within 45 days from the date of this release.
The resource estimate is based on results from 77,097 metres of historical drilling in 1,158 drill holes (9 core and 1,149 reverse circulation or rotary), as well as 59,852 metres in 222 holes, including 74 core holes and 148 reverse circulation holes drilled by Pilot Gold. Quality-control data generated during the various drill programs conducted at Kinsley were independently verified by MDA as part of the project review. The resource model consists of a detailed three-dimensional geological model including lithological, structural and gold domains derived from 25 metre-spaced sections. The low, medium and high-grade gold domains, in turn, were used to constrain the interpolation of gold grades. Blocks measure 5 x 5 x 5 metres. A total of 10,016 individual assay intervals averaging 1.527 metres in length were composited into a total of 10,037 composite intervals of 1.524 metre length. Gold assay data was reviewed statistically and visually to determine appropriate grade capping levels by domain. A total of 21 gold assays were capped prior to compositing based on the evaluation of probability plots by gold domain. In addition to the capping of assay data, the impact of anomalously high gold values was controlled by restricting their range of influence in the estimation process. Gold grades were interpolated using inverse distance to the third power (ID3).
For mineralization to be classified as Indicated, the following criteria were used:
- Indicated (Secret Canyon Shale): minimum of three composites; minimum of 2 holes within an average distance of 25 metres from the block;
- Indicated (All Other Mineralization): minimum of three composites; minimum of 2 holes within an average distance of 20 metres from the block;
All remaining estimated blocks that were not classified as indicated and that meet the elevation critieria summarized below were classified as inferred.
To ensure reasonable prospects of economic extraction, the project resources were limited to elevation levels as defined by Whittle pit shells. A pit optimization was run using a $1,300/oz gold price and parameters applicable to: (i) oxidized, potentially heap-leachable mineralization - $2.50/t processing cost, $1.41/t General and Administrative ("G&A") cost, and a gold recovery of 75%; (ii) mixed and unoxidized mineralization that could potentially be processed by flotation, leaching of the flotation tails, and custom oxidation by roaster or autoclave - $32.00/t processing cost, $7.04/t G&A cost, and 85% recovery; and (iii) mineralization hosted within the Secret Canyon Shale, which potentially could also be processed by flotation, leaching of the flotation tails, and custom oxidation by roaster or autoclave - $28.30 processing cost, $7.04/t G&A cost, and 95% recovery. The pits were used to define the following maximum depths below the topographic surface for the potential open-pit resources at Kinsley Mountain - 125 meters below the topographic surface on the east side of the Kinsley Range and 350 meters below the surface on the western side.
Tonnage estimates are based on 129 bulk specific gravity determinations completed by ALS Laboratories for Pilot Gold, as well as historical data, which were used to assign average values to oxidation domains of the block model. Pilot Gold drill samples were assayed by ALS Laboratory in Vancouver, B.C. for gold by Fire Assay of a 30 gram (1 assay ton) charge with AAS finish, or if over 5.0 g/t, were re-assayed and completed with a gravimetric finish. QA/QC included the insertion and continual monitoring of numerous standards and blanks into the sample stream, and the collection of duplicate samples at random intervals within each batch.
