SolidusGold Reports on Preliminary Economic Assessment for the Wind Mountain Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan. 12, 2015) - SolidusGold Inc. ("SolidusGold" or the "Company") (TSX VENTURE:SDC) is pleased to report on its recently filed technical report for the Wind Mountain gold and silver property in Nevada.

The report, entitled "Technical Report and Preliminary Economic Assessment, Wind Mountain Gold-Silver Project, Washoe County, Nevada" dated December 24, 2014 and prepared by Mine Development Associates Inc. ("MDA"), (the "Report"), is available on the Company's profile at www.sedar.com.

Solidus' Interim CEO, Steven Khan, commented "We are very pleased with the current PEA, which confirms our belief that the Wind Mountain project provides significant value and opportunity to our shareholders. We look forward to advancing the project under the recommendations of the Report".

The Wind Mountain Project is a past producing heap leach low-sulphidation-type gold and silver property consisting of 150 claims totaling approximately 1,147 hectares located within the highly prospective Walker Lane Gold trend approximately 160 kilometres northeast of Reno, Nevada, with good road access and power. The Company holds an option to acquire a 100% interest in the Wind Mountain Project from Bravada Gold Corporation ("Bravada").

Table 1 below presents the Indicated and Inferred Wind Mountain diluted resources. The oxide resource is reported at a cutoff of 0.005oz Au/T. The unoxidized and mixed zones are reported at a cutoff of 0.010oz Au/T based on the presumption that recoveries will be lower in the unoxidized material.

In addition to the estimated and reported resources listed above, there are four mine dumps that contain a total of about 10 million tons of material. The dumps have variable amounts of sampling. All of the sampling indicates the dumps could average between 0.005oz Au/T and 0.013oz Au/T. Although there are currently insufficient data to estimate grades spatially, and there is a potential sample-selection bias, MDA is optimistic that with further drilling and sampling much of these dumps' grade and tons could be quantified for economic evaluation.

In May 2012, MDA completed a Preliminary Economic Assessment for Bravada Gold (the "2012 PEA"). The 2012 PEA used gold and silver prices and cost assumptions current at the time of the evaluation. Changes in metal prices and cost assumptions since the effective date of the 2012 PEA do not have a material effect on the conclusions of the current Preliminary Economic Assessment ("PEA"), and all other assumptions and projections of the 2012 PEA continue to be appropriate as at September 30, 2014, the Effective Date of the Report.

The PEA assumes open-pit mining using conventional trucks and shovels and run-of-mine leaching of the Indicated and Inferred resources summarized in the following table:

Table 2 In-pit PEA Resources

K Tons Ozs Au/t K Ozs Au Ozs Ag/T K Oz Ag
Indicated 42,064 0.011 446 0.26 10,793
Inferred 2,208 0.008 18 0.18 404
In-pit resources are reported using a 0.006 oz Au/t cutoff

A gold price of $1,300 per ounce and a silver price of $24.42 per ounce were used for the economic evaluation. The PEA assumes that all material sent to run-of-mine ("ROM") leach pads is amenable to heap leaching. Economic highlights include:

  • Undiscounted life-of-mine pre-tax cash flow of US$63.3 million and US$42.2 million after-tax;

  • Net present value (5% discount rate) pre-tax of US$42.9 million and US$26.5 after-tax;

  • Pre-tax internal rate of return of 29% and 21% after-tax;

  • Payback period of 2.24 years on a pre-tax basis and 3.3 years after-tax;

  • The estimated pre-production capital cost of the mine is $45.4 million;

  • Life-of-mine cash cost of $859 per equivalent ounce of gold (includes silver as a credit and Nevada net proceeds tax and royalties as costs, but does not include corporate income tax);

  • Total pre-tax cost of $1,080 per equivalent ounce of gold (includes silver as a credit and Nevada net proceeds tax and royalties as costs, but does not include corporate income tax);

  • Strip ratio is 0.71 tons of waste for each ton of leachable material; and

  • 288,000 ounces of gold and 1,680,000 ounces of silver are recovered (320,000 gold equivalent).

(Note that a preliminary economic assessment is preliminary in nature and it includes Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be classified as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.)

Economic Parameters and Assumptions

The mine and process production schedules were used along with the economic parameters to estimate the project cash-flow. The base case cash-flow assumes $1,300/oz Au and $24.42/oz Ag for revenue. The Agnico-Eagle royalty is assumed to be bought down to 1% NSR; however, the Fuller royalty is paid at the rate of 3% NSR due to the smaller amount of gold and silver ounces produced from the royalty area.

Nevada proceeds tax has been included into the operating costs. Deductions for exploration and acquisition costs are made on a straight-line 5-year basis. Capital expenditures are also depreciated on a 5-year basis. Corporate taxes are calculated assuming a 34% rate.

Conclusions and Recommendations

The Report concludes that the Wind Mountain property is a property of merit and warrants additional exploration as well as economic studies. The project location and infrastructure are favorable for mine development, and should the project advance through feasibility with positive results, improvements to necessary infrastructure (power, water, access, housing, etc.) should be reasonably inexpensive. There are no known environmental, social, or logistical impediments to developing a mine at Wind Mountain.

The PEA recommends a two Phase work program. Phase I proposes an expansion and in-fill drill program, potentially connecting the Breeze, Deep Min and Wind resources, and thereby possibly expanding the current PEA pit. Also in Phase I, a drill program is planned to follow up on the Connector target. Phase II plans include cyanide shaker tests, metallurgical and modeling studies, collection of baseline data in the proposed heap leach facility area, geotechnical and hydrology studies, drilling of historic waste dumps and a prefeasibility study.
