Lundin Gold Announces a Positive Feasibility Study for the Fruta Del Norte Project and Conference CallJune 6, 2016
VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 6, 2016) - Lundin Gold Inc. ("Lundin Gold" or the "Company") (TSX:LUG)(OMX:LUG) is pleased to announce the results of an independent Feasibility Study ("FS") for its 100% owned Fruta del Norte Project ("FDN" or the "Project") in Ecuador. The FS has been prepared by Amec Foster Wheeler, with the support of four other globally recognized, leading engineering firms, and is being summarized into a Technical Report (the "FDN Technical Report") to be filed on SEDAR in accordance with National Instrument 43-101 ("NI 43-101"). The FS confirms that the Project will support an economically viable and robust, high grade underground gold mine. All dollar amounts are quoted in U.S. dollars ("$") and all cash cost information is net of silver by-product credits.
Lundin Gold President and Chief Executive Officer, Ron Hochstein, remarked that, "The Feasibility Study provides a solid basis to enable Fruta del Norte to advance immediately into development, ultimately becoming a landmark, high quality and profitable mining operation, adding great value to the Company, its shareholders and the people of Ecuador. With the support of the Government of Ecuador, we look forward to building a historic high grade gold mine in Ecuador."
"The Feasibility Study results present a unique opportunity for the Company and its shareholders", remarked Lundin Gold Chairman, Lukas Lundin. "The results confirm our expectations for Fruta del Norte, which is one of the world's largest undeveloped gold deposits, validating the original commitment of the Board of Directors, management, our investors and Ecuador's stakeholders to push forward with this exciting project."
Feasibility Study Highlights
- Mineral Reserves totaling 4.82 million ounces of gold and 6.34 million ounces of silver (15.5 million tonnes at 9.67 g/t Au and 12.7 g/t Ag);
- Average annual gold production of 340,000 ounces at an average life of mine ("LOM") total cash cost of $553/oz and a LOM all-in sustaining cash cost ("AISC") of $623/oz, placing FDN in the lowest cash cost quartile globally;
- LOM production of approximately 4.4 million ounces of gold and 5.2 million ounces of silver over an initial 13-year mine life using an average gold recovery of 91.7% and average silver recovery of 81.5%;
- Estimated Project capital cost, including contingency, of $669 million, net of taxes;
- Targeted start of construction in mid-2017;
- Expected first gold production in first quarter 2020 with first year of full production in 2021;
- Project economics at a gold price of $1,250/ounce and a silver price of $20/ounce resulted in the following:
|Net Present Value at a 5% discount rate (NPV5)||$1,283 million||$676 million|
|Internal Rate of Return (IRR)||23.8%||15.7%|
|Capital Payback (yrs)||3.7||4.5|
- All figures are reported on a 100% equity project basis valuation. Capital payback is calculated based on start of production.
- Economic valuation is presented using a start date of July 1, 2017.
- The cash flow to be generated over the initial three years, annual average over the first 10 years and LOM are shown in the following table.

The Project sensitivity analysis indicated that a $100/oz variation from the base case gold price had the following impact on the Project after tax economics, with silver held at $20/oz.
|$1,150 oz Au||Base Case
$1,250 oz Au
|$1,350 oz Au|
Further Optimization, Cost Reductions and Project Potential
The Company believes there are potential opportunities to further improve the economics of the FDN Project through:
- Review of the mine plan to potentially improve the production ramp-up and optimization of the mining methods to increase the use of transverse-long-hole stoping ("TS") over the higher cost, lower productivity drift and fill ("D&F") methods;
- Further metallurgical testwork to increase the ratio of doré versus gold in concentrate produced through gravity concentration of flotation concentrate to recover additional free gold;
- Evaluation of aggregate supply for the Project construction and supply of aggregate for backfill. Currently the Project is relying on a quarry operation to be developed on site. Further analysis of alternative sources needs to be completed which could result in lower capital and operating costs;
- Evaluation of owner self-perform construction, which could result in capital cost savings versus the traditional Engineering, Procurement and Construction Management approach that was used for the FS. The Company will also study other potential ways to reduce the capital cost; and
- Potential extension of LOM, perhaps materially, in two ways: (i) through the inclusion of significant additional Mineral Resources not included in the initial mine plan; and (ii) through the identification of mineralization as a result of on-going and future exploration on the Company's concessions which could support the conversion of Mineral Resources to Mineral Reserves.
Benefits to Ecuador
The FS confirms that FDN will provide significant benefit to Ecuador at the local, provincial and national levels. Some of the direct benefits include:
- During construction direct employment, including employees of the Company and contractors is estimated to peak at approximately 2,000;
- During operations the estimated employment is approximately 900, including employees of the Company and contractors. This does not take into account the numerous indirect jobs created with suppliers, services, etc. for the mine operations;
- Improvement of local and regional infrastructure;
- Continuation of existing community investment programs, small business development and support of cultural development; and
- Based on a gold price of $1,250 per ounce, the Project is anticipated to generate payments to the Government in the form of royalties, taxes and profit sharing of approximately $928 million over the LOM.
Feasibility Study Details
Mineral Resources for the FDN deposit were estimated using drill hole data available to December 31, 2015 as shown in Tables 1 and 2 at a cutoff grade of 3.5 g/t Au. The Mineral Resources are contained within three main geological domains; Xh_Vn, Xh_Ip, and M_South. The Xh_Vn domain represents 85% of the tonnage classified within the Indicated Mineral Resource category. It also has the highest average gold grade compared to the other two domains. More than half the tonnage in Xp_Ip is classified into the Indicated Mineral Resource category. All of M_South domain is classified as Inferred Mineral Resources.

- The Qualified Person for the estimate is David Ross, P.Geo., an employee of Roscoe Postle and Associates ("RPA"). The estimate has an effective date of December 31, 2015.
- Mineral Resources are reported inclusive of those Mineral Resources that were converted to Mineral Reserves; Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
- Mineral Resources are reported at a cut-off grade of 3.5 g/t Au; which was calculated using a long-term gold price of $1,500/oz.
- Mineral Resources are constrained within underground mineable shapes that assume a minimum thickness of 2 m; metallurgical recovery of 94%; total operating costs of $145/t milled (mining cost of $60/t milled; process costs of $35/t milled; G&A costs of $15/t milled; surface infrastructure costs of $28/t milled; concentrate transport and treatment costs of $7/t milled); royalties of $71/oz and selling costs of $65/oz.

Mineral Reserves and Mining
The estimated Mineral Reserves, presented by mining method, are shown in the following table.
Table 3 - Probable Mineral Reserves as at April 30, 2016
|Transverse Long Hole Stope||8,404||8.97||2,423||10.4||2,813|
|Drift & Fill||5,533||11.15||1,984||16.9||3,003|
|Development >4.7 g/t Au||1,158||9.70||361||11.6||434|
|Development >2.7 g/t Au||394||3.72||47||7.4||94|
- The Qualified Person for the Mineral Reserve estimate is Alejandro Sepulveda, RM CMC an NCL employee.
- Mineral Reserves have an effective date of April 30, 2016. All Mineral Reserves in this table are Probable Mineral Reserves. No Proven Mineral Reserves were estimated.
- Mineral Reserves were estimated using a $1,250/oz gold price. Mining cost assumptions for transverse stoping (TS) $61.0/t; mining costs for drift-and-fill (D&F) stoping $80/t. Other costs and factors common to both mining methods were process and other costs $75.8/t, dilution factor 10%, concentrate transport and treatment charges of $6.7/t. A royalty of $71.1/oz/t Au and a gold metallurgical recovery of 93.9% was assumed.
- Gold cutoff grades were 4.7 g/t for TS and 5.3 g/t (elevated to 6.8 g/t) for the D&F.
- Silver was not used in the estimation of cutoff grades but is recovered and contributes to the revenue stream. The average silver metallurgical recovery is 81.6%. The silver price assumption was $20/oz.
- Tonnages are rounded to the nearest 1,000 t, gold grades are rounded to two decimal places, and silver grades are rounded to one decimal place. Tonnage and grade measurements are in metric units; contained gold and silver are reported as thousands of troy ounces.
- Rounding as required by reporting guidelines may result in summation differences.
Twin declines will be constructed, and will use a spiral to gain depth to maximize the distance from the surface, so that a vertical distance of approximately 155 m below the Machinaza River can be obtained. The mine ramp will be located central to, and will be approximately 50 m offset from, the main workings to the east of the deposit. The ramp configuration will enable haulage trucks to achieve higher average haul speeds and maintain safety standards. The ramp will be developed nominally at a 15% gradient.
Levels will be developed to access the strike extents of the deposit and connect the development to the return air raise (RAR in the north) and fresh air raise (FAR in the south) in order to establish flow-through ventilation.
Stope cross-cuts are required to access sill development from the haulage drifts, as well as connecting sill development within a given stope line separated by waste. Development will be centrally located within a given stope. The top development in a stope will initially serve as the drill horizon for the stope below, and then as the mucking horizon for the stope above. The bottom development in a stope will serve as the mucking horizon for the stope above.
Computerized mine planning and scheduling techniques were employed for the planning and optimization of the underground mine. DESWIK and other mine design computer software packages were used extensively. In the good-fair geotechnical domains a TS size of 20 m long x 12 m wide x 25 m high was designed. In the more challenging geotechnical zones D&F with 4 m wide x 4 m high flat back drives was designed. Production levels will have a 25 m spacing for TS and 20 m spacing for D&F. There are a total of 15 working levels. The TS stopes will be mainly backfilled using paste backfill while the D&F stopes will be backfilled using cemented rock fill.
The Fruta del Norte ore contains gold in the following forms:
- Fine free gold;
- Coarse free gold;
- Gold contained in sulphides (refractory); and
- Gold contained in other forms (silicates etc.)
FDN ore will be processed using a gravity, flotation and leaching ("GFL") flow sheet. The GFL process is best placed for recovery of the FDN gold because of the manner in which the gold is contained in the ore. Following a conventional SAG/ball mill grinding circuit, the gravity circuit will recover the coarse free gold, and small amounts of fine free gold and gold contained in sulphides. Following grinding and gravity, the flotation circuit is capable of recovering the gold associated with sulphides (pyrite). The flotation tailings will be treated in a CIL circuit that will recover the fine gold. The final tailings will be either filtered and sent to the mine as paste back fill or deposited in a conventional tailings storage facility.
Over the life of the mine, approximately 70% of the gold will be produced in concentrate and the remainder in doré. The silver production is approximately 82% in concentrate and 18% in doré. The concentrate is anticipated to have an average gold grade of 149.3 g/t and will be a marketable concentrate with no significant penalty elements. The doré is anticipated to contain above 98% precious metals. The precious metals portion is expected to contain approximately 60% gold and 40% silver.
Capital & Operating Costs
The initial capital cost is estimated to be $669 million. This capital cost was estimated under the assumption that any expenditures by the Company prior to the start of construction on July 1, 2017 in the FS are a sunk cost and are not included the estimate shown in Table 4. The sustaining capital is estimated to be $263 million and closure costs are projected to be $29 million.
Table 4 - Capital Cost Summary
|Capital Items ($M)||Initial Capital||Sustaining Capital||Reclamation & Closure|
|Tailings / Reclaim Water Facilities||31||68|
|Sub-Total - Direct Costs||426|
Note: Numbers may not add due to rounding.
The initial capital cost estimate does not include taxes estimated at $91 million. Approximately $78 million of the taxes will be recovered once production begins. The financial model assumes an additional $15 million in employee severance allowance to be paid between 2031 and 2033. A total of $430 million in sunk costs through June 30, 2017 has also been assumed, which includes costs incurred by Lundin Gold and previous owners.
The LOM operating cost estimate is $118/t of ore. The operating costs were estimated based on process design criteria, equipment lease rates (if applicable), labor, reagents, power, fuel, explosives, maintenance and other miscellaneous costs. All costs are in Q1 2016 dollars. Table 5 shows that the mining costs are the largest component of the overall operating cost, followed by process, G&A and surface infrastructure.

|On site operating cost||422|
|Treatment & Refining charges||78|
|Royalties & production taxes||75|
|By-product silver credit||(22)|
|AISC per oz||623|
Note: Numbers may not add due to rounding.
The planned access to the FDN site will be from the nearby community of Los Encuentros, where the Company has a local office. The new access road will be 22 km long, a portion of which will benefit public traffic.
The power requirements are expected to be met by a short extension to the regional high voltage transmission network. A single circuit 230 kV dedicated transmission line, 11 km long, will be built extending from the El Pindal substation, to feed the Project.
Social & Environmental
In January 2013, FDN applied for and was granted an Environmental License for the mine, following submission of an Environmental Impact Assessment ("EIA"). The changing footprint due to the new Feasibility Study and the implementation of the beneficiation phase (process plant and associated facilities) requires an amended EIA and likewise a revision to the existing Environmental License.
The Terms of Reference for the amended EIA were approved in late-April, which allowed for the immediate submission of the draft amended EIA to the Environmental Ministry. The Ministry had previously unofficially commented on the draft amended EIA and its observations were reviewed and resolved. In conjunction with the Ministry, the public participation process has begun and will take approximately 60 days. The EIA schedule indicates that formal approval of the EIA and the Environmental License are expected to be issued early in fourth quarter 2016.
The two water permits required for project development have been submitted to the relevant authorities for review and approval.
- Submittal of Phase Change Application for La Zarza concession, which hosts the Project, in June, 2016;
- Approval of Phase Change Application expected prior to the end of August, 2016;
- Start of basic engineering and Early Works program in third quarter 2016;
- Receipt of Environmental License and water permits in fourth quarter 2016;
- Signing of Exploitation Agreement and payment of $25.0 million advance royalty payment by January, 2017;
- Mobilization of portal and mine contractors in second quarter 2017;
- Project financing in place by mid-2017;
- Start of massive earthworks to prepare site in fourth quarter 2017;
- Start of construction of process plant in first quarter 2018; and,
- Expected first gold production in the first half of 2020 with first year of full production in 2021.
The next phase of the FDN Project is Basic Engineering and an Early Works program. The main objectives of the Early Works programs are to provide the infrastructure, services and facilities to support commencement of the mine twin decline construction and to advance the Project in a fast tracked manner. Basic engineering will focus on completing optimizations and remaining field investigations and other activities to support an efficient project start. These programs are planned to start in the third quarter 2016 and are anticipated to be completed by the end of the second quarter 2017.
