Vancouver, B.C., June 15, 2017. Desert Star Resources Ltd. (TSX-V: DSR) (“Desert Star” or the “Company”) is pleased to announce it has signed a definitive agreement dated June 15, 2017 (the “Agreement”) with Capstone Mining Corp. (“Capstone”) to acquire 100% of the Kutcho high grade copper-zinc-gold-silver project (“Kutcho”). The consideration for the acquisition of Capstone’s wholly-owned subsidiary Kutcho Copper Corp. (the “Acquisition”), which owns Kutcho includes C$28.8 million in cash plus such number of common shares in Desert Star, such that, subsequent to the completion of the Acquisition and any concurrent financing, Capstone will own 9.9% of the issued and outstanding shares of Desert Star.

Desert Star also announces the results of an updated Prefeasibility Study (“2017 PFS”) prepared in accordance with National Instrument 43-101 for the Kutcho project. The base case estimate of this study generates an after-tax net present value (NPV) at an 8% discount rate of C$265 million and an internal rate of return (IRR) of 27.6% using metal prices of US$2.75/lb copper, US$1.10/lb zinc, US$17.00/oz silver and US$1,250/oz gold and a currency exchange rate of 0.75 USD/CAD.

In connection with the completion of the Acquisition, the Company proposes to significantly strengthen its management team and board members with a number of new appointments including Mr. Stephen Quin, President & CEO of Midas Gold Corp. and former CEO of Sherwood Copper Corp., Mr. Bill Bennett, former BC Mines Minister and Allison Rippin Armstrong, former VP of Sustainability for Kaminak Gold Corp. Additional proposed appointments and complete bios are described further below.

“The acquisition of the Kutcho project represents a transformational growth opportunity for the company and its shareholders,” stated Vince Sorace, President & CEO of Desert Star Resources. “We believe Kutcho is an exceptional opportunity, with significant near-term upside potential in both the project economics and expansion of the existing mineral reserves and resources. Desert Star is guided by an experienced board, management and technical team with experience in project development, permitting and finance, all committed to working closely with First Nations, local communities and all levels of Government. We look forward to advancing Kutcho to a fully permitted status with strong First Nations, community and regulator support.”

Project Overview

  • The Kutcho project is located in northern British Columbia, approximately 100 kilometres east of Dease Lake and Highway 37, and consists of one mining lease and 46 mineral exploration claims encompassing 17,060 Hectares.
  • Mineralization at Kutcho comprises three known “Kuroko-type” volcanic massive sulfide (“VMS”) deposits aligned in a westerly plunging linear trend. The largest deposit, Main, comes to surface at the east end of the trend, with Sumac followed by Esso down plunge to the west.
  • Over C$50 million of historical project expenditures that provided the basis for the 2017 updated PFS. Desert Star’s study includes parameter changes consistent with current market conditions, such as capital expenditures, operating costs, metal prices and foreign exchange rate.

2017 PFS Highlights

  • Pre-tax NPV (8% discount rate) of C$423 million and IRR of 34.6%
  • After-tax NPV (8% discount rate) of C$265 million and IRR of 27.6%
  • Life of mine (“LOM”) net pre-tax cash flow C$801 million and LOM free cash flow (after-tax) C$533 million
  • 12 year mine life with 2,500 tonne per day production rate for a total life-of-mine payable production of 378 million pounds of copper and 473 million pounds of zinc, plus by-product gold and silver
  • Average annual production of 33 million pounds of copper and 46 million pounds of zinc, plus by-product gold and silver
  • Initial capital costs, including 15% contingency, for a 100% owner-operated mine are estimated at C$220.7 million excluding sunk capital to the start of construction
  • Operating costs of C$73.72/tonne of material milled
  • Unit operating costs of US$1.60/lb copper excluding by-products, and US$0.59/lb copper net of by-products
  • Pre-tax payback of 3.3 years and post-tax payback of 3.5 years
  • Probable Mineral Reserve(1) at a 1.5% copper cut-off grade of 10.4 million tonnes averaging 2.01% copper, 3.19% zinc, 0.37 g/t gold and 34.61 g/t silver. A 1.5% Cu cut-off grade was used for mineral reserve estimation and is based on the 2011 mine plan.

Proposed Work Program

Desert Star has developed plans to advance the Kutcho project from the 2017 PFS to a fully permitted project with a feasibility study completed by the end of 2019. This work includes additional geotechnical work on the deposits, a drilling program to collect metallurgical samples and upgrade a portion of the inferred mineral resources to the measured and/or indicated categories so they could potentially be included in future studies, additional metallurgical test work to optimize metallurgical parameters, and environmental baseline studies.

Potential Exploration Upside

Significant exploration upside has been identified through historic work including several priority drill ready targets prospective for the discovery of new deposits including:

  • mineralized drill intersections along strike and down plunge to the west from the Esso deposit (one of three VMS deposits comprising the Kutcho project) including 7.2 metres @ 1.96% copper, 5.24% zinc, and 18.0 g/t silver in DDH 94-B3;
  • the FW Zone, a relatively narrow sulphide lens (2 to 5 metres thick) that lies beneath the Main Zone and currently has an historic estimate* – prepared as an internal document for Esso in 1979, of 230,000 tonnes averaging 1.47% copper, 5.52% zinc, 0.4 g/t gold and 43.7 g/t silver.
  • In addition, there is favourable untested stratigraphy east of the Main Zone, and on the southern portion of the property where the Kutcho time equivalent sulphide horizon is fold repeated.

*A Qualified Person has not completed sufficient work to classify the historic estimate tabulated above as current mineral resources and the issuer is not treating the above mineral estimates as current mineral resources. The historic estimate is uncategorized and does not use the categories (“inferred”, “indicated” or “measured” mineral resource, or “probable” or “proven” mineral reserve) set out in Sections 1.2 and 1.3 of NI 43-101 as defined by the Canadian Institute of Mining, Metallurgy and Petroleum, are not compliant with the NI 43-101. The historical estimate is relevant to obtain a reference to mineral potential present on the property. The Company has not undertaken any verification of the historical data upon which the historical estimates are based on.


The company has engaged the following advisors:

  • Fort Capital as its financial advisor in connection with the Acquisition
  • Macquarie Capital Markets Canada Ltd. as its financial advisor and lead agent with regard to any acquisition financing
  • C3 Alliance Corp as a strategic advisor on Community and First Nations engagement, project permitting and government relations
  • JDS Energy & Mining Inc. as its lead technical consultant
  • Farris, Vaughan, Wills & Murphy LLP as its legal advisor

(1) A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances a Measured Mineral Resource, demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.

(2) Copper equivalencies are based on commodity prices of $2.75/lb Cu, $1.10/lb Zn, $17.00/oz Ag and $1,250/oz Au and recoveries of 84.7% Cu, 75.7% Zn, 48.0% Ag, 41.2% Au. Actual economic parameters, including recoveries, are subject to change as additional test work and studies are completed.

(3) The economic analysis contained in the 2017 PFS does not include inferred resources.

Cut-off Grade Sensitivities

As part of the 2017 PFS update, a new calculation for the cut-off value was conducted that returned a mill-head NSR (including recoveries) cut-off value of $74/t excluding royalties and sustaining capital. This converts to a 0.8% copper cut-off, including by-product credits. Tables 6-9 demonstrate the sensitivity to cut-off grade for the Measured, Indicated and Inferred Mineral Resources of the Main, Esso and Sumac deposits.
