Miranda Gold Files Updated Preliminary Feasibility Study For The Lucky Shot Project, Alaska
Vancouver, BC, Canada – April 6, 2017 – Miranda Gold Corp. (“Miranda”) (TSX-V: MAD) is pleased to announce it has filed an updated Preliminary Feasibility Study (“PFS”), NI43-101 technical report, for Alaska Gold Torrent, LLC’s (“Gold Torrent”) and Miranda’s Lucky Shot Project in Alaska. The historic Lucky Shot Mine is in the Willow Mining District.
The report is titled “National Instrument 43-101 Technical Report: Preliminary Feasibility Study for the Lucky Shot Project, Matanuska-Susitna Borough, Alaska, USA” prepared by Hard Rock Consulting (“HRC”), Lakewood, Colorado. Miranda has previously referred to the Lucky Shot Project as the Willow Creek Project.
The updated measured and indicated resource at a cutoff of 5.0 g Au/t is 206,600 tonnes at an average grade of 18.3 g Au/t containing 121,500 ounces gold and an additional 59,000 tonnes inferred at an average grade of 18.5 g Au/t containing 35,100 ounces, or 156,600 ounces total at 18.3 g Au/t in both categories.
The proven and probable reserve, internal to the above resource, at a cutoff of 7 g Au/t and 34% mine dilution is 174,000 tonnes at 15.6 g Au/t containing 87,504 ounces gold. Stopes would be mined using either the open stull or waste pillar method.
In the PFS, the project produces 79,114 ounces of gold in 5 years of production, with 25,645 ounces annually, at peak production. Net cash flow before taxes for the same operating period is US$14,693,746. The forecast “All in Sustaining Costs” (ASIC) for the project are US$675 per ounce.
Miranda will receive 10% of the proceeds until Gold Torrent recovers US$10M of initial capital investment; 20% until Gold Torrent recovers capital in excess of US$10M; and 30% thereafter. Miranda also has an option to purchase, on installment payments, a 3.3% NSR on all production for the life of mine.
Gold Torrent forecasts a Lucky Shot production start up of December 2018. Planned underground exploration drilling after startup is intended to add open mineralization to the mineral resource and to support conversion of mineral resources to mineral reserves.
Miranda’s CEO Joseph Hebert comments that: “The Lucky Shot Project will represent Miranda’s first participation in production from its joint venture business model. While currently a modest project, Lucky Shot will place Miranda in a small group of primary explorers with cash flow, and will also fund our core business which continues to be world-class discovery in Colombia”.
Highlighted Tables from the PFS are:
The proven and probable mineral reserves for the project as of May 31, 2016 are summarized in the table below:
Notes: (1) Reserve cut-off grades are based on a 7.0 g/t gold equivalent with 78.3:1 silver to gold ratio. (2) Metallurgical recoveries were estimated at 90.0% silver and 91.8% for gold. (3) Mining recoveries of 90% were applied. (4) Minimum mining widths were 0.8 meters. (5) Dilution factors averaged 34%. Dilution factors are calculated based on internal stope dilution calculations and external dilution factors of 20%. (6) Price assumptions are $15 per ounce for silver and $1,175 per ounce for gold. (7) Figures in table are rounded to reflect estimate precision; small differences generated by rounding are not material to estimate
The mineral resource is summarized in the table below:
Note: Measured, Indicated and Inferred mineral classifications are assigned according to CIM Definition Standards. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability and there is no guarantee that mineral resources will be converted to mineral reserves. (1) The mineral resource estimate was prepared by HRC based on data and information available as of February 1, 2016. The 2016 Measured, Indicated and Inferred mineral resources are reported considering a base case estimate that applies a cutoff grade of 5 g/t Au based on the estimated operating costs, historical recoveries, and a $1,265/oz gold price.

The Lucky Shot economic profile:
The Lucky Shot Project is located 166 km by road, north from Anchorage, Alaska. It is east of the town of Willow and can be accessed by a well-maintained gravel road. The project covers the majority of the historic Willow Creek mining district and is comprised of 43 patented lode mining claims and 62 State of Alaska lode mining claims for a total of approximately 4,290 hectares. Numerous historical mines occur on the property including the Coleman, Lucky Shot, War Baby, and Gold Bullion Mines. These mines exploit faulted segments of the same vein system. Historic production from land controlled by the Gold Torrent-Miranda joint venture is estimated at greater than 500,000 ounces at 41.14 g Au/t (1).
Gold is found in shallow dipping mesothermal quartz veins. Gold is predominantly free and associated with telluride. Very little gold is occluded in sulfide, and historic milling recovered more than 85% of contained gold through gravity separation, demonstrating very favorable metallurgy, and non-chemical processing.
There is excellent potential for extending mineralization down-dip and along strike from historic workings. The Murphy area, drilled in 2006 and 2007 extends the strike of the mineralized vein system to 1,800 meters, or 600 meters beyond historic workings. Two of five holes drilled in the Murphy show high-grade mineralization (up to 0.98 meters at 54.6 g Au/t) 300 meters below the surface. The Murphy area mineralization is not delineated and supports significant upside potential near historic workings.
In 2014, Miranda completed a 234-station soil grid on Bullion Mountain centered approximately two kilometers from the Coleman and Lucky Shot mines. The highlight of this work was the discovery of three quartz vein sub-crops that assayed 50.74 g Au/t, 17.05 g Au/t and 18.5 g Au/t. These anomalies strongly suggest that the Lucky Shot veins extend as near continuous faulted segments from the Lucky Shot Mine, for four kilometers to Bullion Mountain. The Bullion Mine produced 77,000 ounces at an average grade of 48 g Au/t.
The resource occurs on private surface patented claims. Permits will be issued by the State of Alaska.
