ATAC Announces Positive PEA Results for the High-Grade Oxide Gold Tiger Deposit, Rackla Gold Project-Yukon

VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 07/23/14 -- ATAC Resources Ltd. (TSX VENTURE:ATC) is pleased to announce the completion of a positive Preliminary Economic Assessment ("PEA") for the oxide portion of the Tiger Deposit located at the western end of the Company's 100% owned Rackla Gold Project, Yukon. The Tiger Deposit was discovered in 2007 and is distinct from the more recent larger scale Carlin-type discoveries located 100 km to the east, which remain the exploration focus of the Company.

The lead engineering firm for the PEA was Kappes Cassiday & Associates ("KCA") (metallurgy, processing, infrastructure, financial analysis) in cooperation with Tetra Tech, Inc. ("Tetra Tech") (mining), Giroux Consultants Ltd. (mineral resource), Resource Strategies (environmental and permitting) and Gerald G. Carlson, Ph.D., P.Eng. (history, geology, drilling). Unless specified otherwise, all values are shown in Canadian dollars, where 1 CAD = 0.92 USD.

PEA HIGHLIGHTS (using US$1,250 per ounce gold price):

--  Conventional open-pit mining with single-stage, low intensity crushing
    followed by size classification - no grinding or agglomeration needed; 
--  Life of mine ("LOM") production of 2.06 million tonnes of oxide material
    at an average diluted grade of 3.72 g/t gold; 
--  Overall gold recoveries of 89.8% from hybrid heap-leach (87.8% recovery)
    and agitated tank (91.0% recovery) carbon-in-leach ("CIL") process; 
--  Four year, seasonal operation with LOM production of 221,558 ounces of
    gold; 
--  Pre-tax net present value ("NPV") of $52.1 million at a 5% discount rate
    and internal rate of return ("IRR") of 30% with an all-in sustaining
    cash cost of $626(i); 
--  At a US$1,350 per ounce gold price the pre-tax NPV increases to $72.6
    million at a 5% discount rate and IRR of 39.5%; and, 
--  Pit slope engineering, Tiger Deposit infill drilling and exploration of
    numerous untested nearby oxide targets have the potential to enhance the
    value of the project economics.
    (i)All-in sustaining costs are presented as defined by the World Gold
    Council less corporate G&A. 

"Although we remain focused on the Carlin-type gold targets 100 km to the east, we are very pleased with the results of the comprehensive Tiger Deposit PEA. It gives the Company a clear understanding of the potential viability and value of our first Rackla Gold Project discovery, and highlights the advantages of a rare high-grade, at surface, oxide gold deposit that is located in one of the most favourable mining jurisdictions in the world," states Graham Downs, CEO of ATAC. "The simplicity of the mining and processing combined with the approach of modular design and construction for the on-site facilities has resulted in an optimized development scenario for this size of deposit. Additional geotechnical and resource drilling at the Tiger Deposit combined with exploration drilling at over six untested satellite oxide targets has the potential to significantly enhance the PEA and the district potential of the Rackla Gold Project."

Project Description

The Tiger Deposit is located approximately 55 km northeast of Keno City, Yukon. Access to the Tiger Deposit would be by a proposed 51.6 km winter road that utilizes 24.6 km of the existing and permitted Wind River Winter Trail. The deposit is currently accessed by air via a 2,500 foot airstrip located 8 km from the deposit.

An owner-operated open-pit mine, with one year of pre-stripping followed by four years of production is envisioned in the PEA. Average annual production would be approximately 55,389 oz gold with year one production projected to be 78,500 oz gold. A total of 2.06 million tonnes of oxide material at an average diluted grade of 3.72 g/t would be extracted by hydraulic excavator. Based on a geotechnical study, no blasting of mineralized material would be necessary due to its highly weathered and sandy nature. Mining and stockpiling would take place year-round, while processing of mineralized material would occur during May through September (158 days annually) at a rate of 3,300 tonnes per day.

Processing has been designed to begin near the open-pit where material would be fed into a single skid-mounted low-intensity mineral sizer. Material would then be transported downhill by overland conveyor to a modular processing facility to be scrubbed and sized into two size fractions. The study proposes a hybrid approach where approximately 42% of the material (+0.212 mm) would be sent to the heap leach facility. The remaining 58% (finer material) would be sent to the CIL plant. A 50 day heap leach cycle has an estimated gold recovery of 87.8% while the retention time for the CIL plant is 24 hours with an estimated gold recovery of 91.0%.

All major project components for the Tiger Deposit would be engineered and constructed to achieve efficient closure. Heap leach cells would be built annually and progressively reclaimed, while the tailings facilities would be expanded annually and fully reclaimed at closure.

Opportunities to Enhance the Project

ATAC is very pleased with the base case results from the detailed PEA and believes that opportunities exist that could greatly enhance the economics of the project. Some key opportunities include:

--  Future geotechnical studies may permit steeper pit slopes, which could
    potentially capture a greater percentage of the presently known resource
    and/or reduce the strip ratio; 
--  Trade-off studies between owner-operator and contract mining or mining
    fleet leasing could decrease pre-production capital; 
--  Resource expansion and upgrading inferred resources to the indicated
    category may be achieved with a modest drill program; and, 
--  Significant potential exists to increase the resource base and life
    expectancy of the project with the exploration of more than six untested
    satellite oxide gold targets and geochemical anomalies. 

Environment and Community Engagement

Since 2007, the Company has completed comprehensive environmental, water, heritage, geotechnical and metallurgical studies which have resulted in a highly advanced project at the PEA stage. Due to the nature of the geology of the deposit and environmental studies completed to date, permitting would likely be without significant problems.

Community and First Nation engagement began in 2008 with the first Exploration Cooperation Agreement with the First Nation of Na Cho Nyak Dun ("NND") signed in 2010. This Exploration Cooperation Agreement with the NND was recently renewed and provides a framework within which exploration activities and environmental regulatory processes on ATAC's Rackla Gold Project have been and will continue to be carried out. The Rackla Gold Project lies exclusively within the Traditional Territory of the NND.

Going forward

The Company will continue with environmental baseline work and ongoing studies while it explores opportunities to advance or monetize the Tiger Deposit through sole development, joint venture or outright sale.

Project Mineral Resources

Gold occurs in both sulphide and oxide mineralization within the Tiger Deposit. The PEA considers the oxide portion of the deposit. The following two tables show the oxide only resource used for the PEA and the oxide plus sulphide resources for reference only.

The PEA is based on a 43-101 compliant mineral resource estimate completed by Gary Giroux, P.Eng., M.A.Sc. (Giroux Consultants Ltd.) who is a qualified person and independent of ATAC, based on the criteria defined by National Instrument 43-101. Quality control data generated during the various drill programs conducted at the Tiger Deposit were independently reviewed by Giroux Consultants Ltd. as part of the resource study. The full report dated effective November 15, 2011 and titled "Preparation of the Tiger Zone Mineral Resource Estimate" was filed on SEDAR (http://www.sedar.com/) December 1, 2011.

It should be noted that this PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA forecast will be realized or that any of the resources will ever be upgraded to reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. A NI 43-101 technical report for the Tiger Deposit PEA will be filed on SEDAR (www.sedar.com) and ATAC's website (www.atacresources.com) within 45 days.
