VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 30, 2017) - Lundin Gold Inc. ("Lundin Gold" or the "Company") (TSX:LUG)(OMX:LUG) is pleased to report the start of construction of the mine development support facilities on its 100% owned Fruta del Norte Project ("FDN" or the "Project") in Ecuador. In addition, the Company has completed a project update for FDN. The update is based on advancing the design and estimates from the Technical Report entitled "Fruta del Norte - NI 43-101 Technical Report on Feasibility Study" (the "FS") filed by the Company in June 2016. The updated results include a revised mine plan, updated capital and operating costs and a new execution plan based on a self-perform approach versus EPCM. All dollar amounts are quoted in U.S. dollars ("$") and all cash cost information is net of silver by-product credits. This update should be read in conjunction with the FS.

Lundin Gold President and Chief Executive Officer, Ron Hochstein, remarked that, "A remarkable amount of work has been accomplished over the past year to provide a comprehensive update to the project. The result of these efforts has led to a more technically robust and constructible project with an improved execution plan. In addition, first gold production is now scheduled for Q4 2019, versus Q1 2020, and commercial production is achieved over six months sooner than anticipated in the FS. In addition, the update results in an improvement in the economics of the Project."

Highlights

• Based on field investigations and improved mine design, the expected first gold production has been moved forward several months, from first quarter 2020 to fourth quarter 2019;
• The mining rate is expected to ramp up quicker, over a twelve-month period, to an extraction rate of 3,500 tonnes per day ("tpd") until 2022, when the extraction rate is planned to reach 3,600 tpd;
• Average annual gold production is anticipated to exceed 300,000 ounces over 15 years (13 years in the FS) at an average life of mine ("LOM") total cash cost of $561/oz and a LOM all-in sustaining cash cost ("AISC") of $609/oz;
• LOM production is expected to be approximately 4.5 million ounces of gold and 5.5 million ounces of silver;
• Estimated Project capital cost, including contingency and pre-production costs and revenues, is $684 million, net of taxes, compared to $669 million in the FS. This revised estimate includes the cost of mining equipment and the paste plant, estimated at $58 million, previously included in sustaining capital;
• Project economics show an improvement over the FS, at the same gold and silver price assumptions used in the FS ($1,250/ounce of Au and $20/ounce of Ag):

Notes:

1. All figures are reported on a 100% equity project basis valuation. Capital payback is calculated based on start of commercial production.
2. Economic valuation is presented using a start date of July 1, 2017.

Project Update Details

Mining

As a result of a complete review of the mine plan, the updates to the FS are:

• The development schedule was shortened by several months as a result of improved ground conditions based on further field investigations, relocation of certain infrastructure into better ground conditions and better than anticipated contractor development rates.
• Conversion of approximately 1.5 Mt from drift & fill to transverse stoping mining method.
• The revised mine plan has a more even distribution of transverse stoping and drift & fill over the entire life of mine. The Company believes that the extraction sequence is more geotechnically stable and carries less risk than the sequence contemplated in the FS.
• Detailed ventilation modelling resulted in reduced power requirements and the elimination of the north vent raise.

Process

There were no changes to the proposed flowsheet. However, the optimization of the process plant layout resulted in significant reductions in earthwork, concrete and piping quantities.

Capital & Operating Costs

As compared to the FS, LOM capital costs decreased from $932 million to $854 million.

The revised pre-production capital cost is estimated to be $684 million, inclusive of contingency and pre-production expenses and revenues, and net of taxes. Consistent with the FS, this capital cost was estimated on the basis that any expenditures by the Company prior to July 1, 2017 are not included in the estimate. While the FS was developed under an EPCM execution platform, this updated estimate is based on a self-perform / direct hire strategy.

Initial capital cost increased approximately $15 million due to reallocating mine equipment purchases and the paste backfill plant from sustaining capital to initial capital, offset by reductions due to changes in scope, reduction in equipment quotations and the inclusion of pre-production costs and revenues. This capital cost estimate includes all direct and indirect costs to be expended throughout the project execution, starting July 1, 2017 and ending when the plant production reaches commercial production, defined as 70% of the nominal nameplate capacity for three consecutive months, estimated to occur by mid-2020. The capital cost estimate of $669 million in the FS was based on costs up to first production. By comparison, if the FS estimate were stated at commercial production to align with the basis in the project update, the FS estimated capital cost would have been $704 million.

The sustaining capital is estimated to be $169 million (FS - $262 million) and reclamation and closure costs are projected to be $44 million (unchanged from FS).

Capital Cost Summary ($ M)

The capital cost estimate does not include advance royalty payments, working capital requirements, corporate costs, $108 million in indirect taxes and the remaining 2017 Early Works program. Approximately $73 million of taxes will be recovered once production begins.

The LOM operating costs and all-in sustaining costs estimates have also improved compared to the FS. Operating costs are now estimated at $111.84/t of ore, versus $118.04/t in the FS. All costs are in Q2 2017 dollars.
