Sabina Gold & Silver Announces Positive Feasibility Study on Back River Gold Project, Nunavut
Post Tax IRR/NPV of 21.7% and C$539 million
Assumes a gold price of US$1200/oz and C$ exchange rate of 0.87
Conference Call & Webcast Thursday May 21, 2015 at 7:00am Pacific Time
Vancouver, BC — Sabina Gold & Silver Corp (SBB.T), (“Sabina” or the “Company”) is pleased to announce it has received the results of the Feasibility Study (“FS” or the “Study”) for its 100%-owned Back River gold project (“Back River” or the “Project”) in Nunavut, Canada. The FS was led by JDS Energy & Mining Inc.(“JDS”) (mining, on-site infrastructure, off-site infrastructure, logistics, capital costs, operating costs, financial analysis and report preparation) (“JDS”) and contributed to by Hatch Ltd. (“Hatch”) (metallurgy, processing, on-site infrastructure and off-site infrastructure), SRK Consulting (Canada) Inc. (“SRK”) (geotechnical, hydrology, tailings design, waste and water management), AMC Mining Consultants (Canada) Ltd., (“AMC”) (geology), and Knight Piésold Ltd. (“KP”) (geomechanical).
The Back River Gold Belt is located in the West Kitikmeot Region of Nunavut, Canada and is situated approximately 75 km from tide water at Bathurst Inlet. The Project is made up of a series of five claim blocks of which only two (Goose and George) have been the primary focus of exploration and resource development to date.
“Back River offers a rare opportunity for significant high grade gold production by both open pit and underground operations in one of the world’s safest mining jurisdictions. We are very pleased to announce what we believe is a very compelling FS,” said Bruce McLeod, President & CEO. “The FS presents a project that has been designed on a fit-for purpose basis, with the potential to produce ~350,000 ounces a year for ~10 years with a rapid payback of 2.2 years. At a US$1,200 gold price and a 0.87 exchange rate, the Study delivers a potential after tax internal rate of return (“IRR”) of approximately 22% with an initial CAPEX of $695 million. Comparing the Study against other projects we believe this is a sound FS that demonstrates the potential of Back River to be a significant Canadian gold producer. Additionally, as part of their recommendations in the FS, JDS has identified the potential optionality to start smaller at Back River which could kick off production on the belt. Such an opportunity would require less initial capital which in these markets may enhance shareholder value. “
Feasibility Study Highlights
The FS was initiated in June of 2014 following the encouraging results of the Preliminary Feasibility Study (“PFS”) on Back River which was announced in October of 2013.
All currencies are in Canadian dollars unless otherwise specified. Base case economics are based on a gold price of US$1200/oz Au and an exchange rate of 0.87 (US$:C$).
The Study’s highlights include:
- The Project could generate a post-tax IRR of 21.7% and net present value (“NPV”) (at 5% discount rate) of $539 million
- The Project could generate Life Of Mine (“LOM”) post-tax net cash flow of $914 million on gross revenues of $4.5 billion with a payback period of 2.2 years (from start of operations);
- Processing rate of 6,000 tonnes per day (“tpd”) could produce an average of ~346,000 oz Au per year (post commencement of commercial production)
- Average production of 413,000 oz Au in years 1 through 4;
- Majority of production from open pit;
- Initial capital estimate of $695 million and sustaining capital estimate of $529 million (including closure);
- Total LOM cash cost estimate of US$535/oz Au (including third party royalties, refining and transport). LOM all-in sustaining cash cost estimate of US$671/ oz Au LOM (including sustaining capital);
- A total of 19.8 million tonnes of ore could be milled over 10 years with a LOM average grade of 5.70 grams per tonne (“g/t”) Au and metallurgical recoveries of 93%;
- Base case assumptions of delivered diesel price of $0.94/L for power generation; and
- Open Pit strip ratio of 7.2:1 over LOM.
Comparison to the PFS
Compared to the PFS, the FS provides:
- Improved economics using a lower gold price
- Longer mine life from increased measured and indicated resources;
- More ounces could be recovered due to improved gold recoveries, notably from the first years of open pit mining resulting in a positive impact on the economics and payback;
- Optimized throughput — increased throughput to 6,000 tpd from 5,000 tpd resulting in higher production yield;
- Improved mine sequencing providing opportunity for smaller initial tailings facility and utilization of open pits for tailings disposal.
BACK RIVER GOLD PROJECT — FS
Economic Analysis and Sensitivities
Economic factors and assumptions include the following:
- Discount rate of 5%;
- Costs based on nominal 2015 Canadian dollar values;
- No application of inflation;
- Values are presented on a 100% ownership basis and do not include management fees or financing costs;
- Exclusion of all pre-development and sunk costs (i.e., exploration and resource definition costs, engineering field work and studies costs, environmental baseline study costs, etc.). Note: pre-development and sunk costs are used in tax calculations;
- Gold price of US$1,200/oz;
- US$:CD$ exchange rate of 0.87;
- Includes estimated third-party net smelter royalties which average 3.3% over LOM
- NWT/Nunavut Mineral Royalties (NTNMR) have been evaluated as part of the after-tax analysis. The Crown royalty is levied on a mine-by-mine basis and is equal to the lesser of 8% of the net value of mine output during a fiscal year, and an escalating rate from 0% to 14% on incremental levels of net value of the mine output during a fiscal year.
- The Back River Mineral Resources considered in the Study are on grandfathered properties subject to royalties under the NTNMR;
- Federal tax rate of 15% and a NWT 12% rate were used to calculate income taxes;
- Canadian Exploration Expense (CEE) and Canadian Development Expense (CDE) tax pools were used with appropriate opening balances to calculate income taxes; and
- Specific capital cost class Capital Cost Allowance (CCA) rates were applied and used to calculate the appropriate CCA the Company can claim during the entire life of the Project.
Pre-tax and after-tax financial performance is summarized in Table 1. Pre-tax results provide a point of comparison with similar projects and are not intended to represent a measure of absolute economic value.

2015 Feasibility Study Parameters
The Back River mineral resource consists of two sites: George and Goose. Each site has four mineable deposits with the majority of the Mineral Resources and Mineral Reserves located at the Goose Site. The Project is based on conventional open pit and underground mining operations that feed a 6,000 tpd whole-ore leach process plant located at Goose, which could produce an average of approximately 346,000 ounces of gold per year as dore bullion over a 10 year mine life with the majority of reserves being mined by open pit..
A total of 19.8 million tonnes (“Mt”) of ore could be mined at a mill head grade of 5.7 g/t au and a projected recovery of 93%. A total of 3.4 Moz Au is projected to be recovered over the life of mine with cash costs of approximately US$535 per oz Au including royalties. All-in life of mine cash costs (including initial and sustaining capital costs) are approximately US$850 per oz Au.
Initially tailings could be stored in a purpose-built storage facility followed by deposition into exhausted open pits at Goose. Mine construction and operations could be facilitated by sealift during the summer months, and an ice road from the marine laydown area (“MLA”) in the winter. Supplies could be brought by sealift to the MLA at Bathurst Inlet and hauled to the Goose mill by winter road.

Geology and Mineralization
The Goose Site consists of four main deposits that contain predominantly structurally-controlled gold mineralization: Goose Main, Echo, Umwelt, and Llama. Gold mineralization is predominantly hosted within the Lower Iron Formation (“LIF”) and, to a much lesser extent, the underlying sediments. The Goose Main, Umwelt, and Llama deposits are associated with anticlinal structures that have been structurally thickened and disrupted, and cut by axial planar felsic dykes, which apparently trace the fluid pathways and are related to mineralization. The Echo deposit is associated with gentle folding of iron formation and a cross-cutting felsic dyke. Mineralization is spatially associated with the felsic dyke.
The George Site consists of six main deposits: Locale 1 (“LOC1”), Locale 2 (“LOC2”), Slave, GH, LCP North (“LCPN”) and LCP South (“LCPS”). Gold mineralization is located within oxide iron formations near the stratigraphic base of this unit. Less significant gold mineralization is also hosted within a silicate iron formation. Gold-bearing zones are associated with sulphide concentrations in the iron formation, and are commonly accompanied by increased quartz veining and attendant alteration of the surrounding rocks.
Each of the MLA, Goose and George sites would have bulk fuel storage tanks, laydown yards, diesel power plants, maintenance shops, accommodation camps, water and domestic waste management facilities, and satellite communications. All-weather airstrips would be located only at the Goose and George sites. In winter, the three sites would only be connected by ice roads. All-weather roads allow for year-round access within each site.
The major infrastructure related to the mining and processing operations at the Goose Site includes the process plant buildings, power plant, truck shop/administration complex, accommodation camp, tailings storage facilities, waste rock storage areas (“WRSA”), water management drainage and storage ponds, and haul roads and equipment to service the underground mines.
The MLA would support the seasonal trans-shipment and staging of construction and operational freight. Because access to the Property is seasonal, the types and capacities of the Project infrastructure have been designed to store and transport the required yearly quantities of equipment, materials, and supplies.
Buildings and facilities at the Goose site would be heated primarily by heat recovered from the power plant as would the Umwelt underground mine ventilation air.
The accommodation camps would be portable, modular units constructed off-site. The construction and mine-site operations phases at the Goose Site would require accommodation for up to 465 workers. The construction and mine-site operation phases at the George Site would require accommodation for up to 150 workers. The construction and port operation phases at the MLA site would require accommodations for up to 75 workers.
The FS includes 100% on-site diesel generated power at Goose, George and the MLA based on a diesel price of $0.94/L for power generation was assumed. The estimated power unit cost averages $0.24/kWh not including capital cost or operating labour at the Goose site. The average annual process related fuel consumption for power generation at Goose is estimated to be 26.3 million litres.
Conventional shovel-and-truck open pits combined with underground mines are projected to provide the process plant feed at a nominal rate of 6,000 t/d or 2.2 (Mt/a) for a period of 10 years. Annual mine production of ore and waste is profiled to peak at 13.6 Mt/a from the open pits, with a LOM waste to ore strip ratio of 7.2. Ore production from underground mining will peak at 1.7 Mt/a and would supplement the feed from the open pits. In order to optimize the Project cash flow, the run of mine ore is planned to be segregated into high, medium, and low-grade stockpiles located adjacent to the processing plant.
The FS contemplates mining starting at Goose in Year -2 and at George in Year 5. Open pit mining at Goose would begin with the Umwelt pit in Year -2 to provide waste rock for construction and enable the stockpiling of high-grade ore prior to the start of plant processing. Open pit mining would then transition sequentially to the Llama, Goose Main and Echo pits. Open pit mining would be completed by Year 6 at Goose. Underground ore production would begin in Year 1 with the Llama mine and then transition to the Umwelt, Goose Main and Echo mines. Umwelt mine, beginning in Year 2, will continue until Year 10. Open pit mining operations at George would transition sequentially from LCPN through LOC1, LCPS and LOC2. Underground mining operations at LOC1, LOC2 and LCPs would begin simultaneously in Year 7.
Open pit mining operations would use a fleet comprising 7 m3 shovels, a 7 m3 front-end loader, 4 m3 excavators, and 64 tonne haul trucks. This fleet would be supplemented by drills, graders, and track and rubber-tire dozers. A 5-m bench height was selected for mining in ore and waste with overall 20 m effective bench heights based on a quadruple-bench configuration.
Underground mining operations would be carried out using post pillar cut-and-fill, drift and fill, and longitudinal open stoping mining techniques. Underground mining would use a combination of two-boom jumbos, long-hole production drills, 10 t load-haul-dump (LHD) vehicles, and 30 t trucks.
In early 2013, a comprehensive metallurgical test program was conducted to further assess the metallurgical performance of the mineralization to support the PFS. A subsequent and more detailed test program commenced in late 2013 and concluded mid-2014 to support the FS.
Based on the 2014 and historical test results, a combination of gravity separation and cyanide leach processes is proposed for the Project.
The 2014 test results are summarized as follows:
- Whole-ore leach showed slightly better metallurgical recoveries when compared to a flotation/regrind/concentrate leach circuit;
- Gold recoveries by gravity concentration ranged from 16 to 76%;
- A weighted 75th percentile Bond ball mill work index (“BWi”) of 15 kWh/t was determined, indicating moderate hardness in terms of grinding requirements; and
- The optimum grind for the ore was determined to be 50 um (P80).
Test work results were used to determine the relationship between mill feed grade and metallurgical recoveries for each of the deposits as shown in Table 5.
Table 5: Gold Recovery Projections
|Mineral Zone||Head Grade
Processing and Recovery
The 6,000 t/d process plant will be designed to use conventional crushing, grinding, gravity concentration, gold leaching by cyanidation, gold adsorption by carbon-in-pulp (“CIP”), and gold recovery from loaded carbon and gravity concentrate to produce gold doré. Cyanide destruction of the tailings would be by an air/SO2 process. The overall design philosophy uses proven equipment with a simple and conventional single-line process flow that can be operated and maintained effectively in an arctic environment.
The Project could produce a total of 19.8 Mt / 16.5 million cubic metres (“Mm3”) of tailings over the LOM. The dedicated Tailings Storage Facility (“TSF”), located adjacent to and south of the Goose Main open pit, was designed to contain the first two years of tailings (3.8 Mt / 3.1 Mm3) behind a frozen foundation dam with an integral liner. The balance (16.0 Mt / 13.4 Mm3) could be deposited into the mined-out Umwelt open pit (Umwelt Tailings Facility) followed by the Goose Main pit (Goose Main Tailings Facility). Ultimately, potentially acid generating (“PAG”) and non-potentially acid generating (“NPAG”) waste rock will be deposited on the TSF once tailings deposition has relocated to Umwelt Tailings Facility followed by the Goose Main Tailings Facility.
Mine construction and operations will have equipment and materials (including fuel) transported mainly from east and west coast ports to the MLA at Bathurst Inlet by sealift during the summer months. Equipment and materials will then be hauled to the Goose and George sites by a winter ice road. Limited amounts of materials will be transported to the sites by aircraft.
The initial capital cost estimate is $695M, as summarized in Table 6.
Table 6: Capital Cost Estimate Summary
|Capital Cost||Pre-Production $M||Production
|Water & Waste Management||19.7||31.9||51.6|
|Total Capital Costs||694.7||525.8||1,220.6|
The capital cost estimates were prepared using first principles, and applying direct project experience. The estimate is based on feasibility-level engineering, quantity estimates, supplier/contractor quotations for equipment and materials, as well as estimated labour rates and productivity factors specific to northern Canadian locations.
The initial capital estimates include all pre-production mining activities (Year -2 and Year -1) and are based on Owner-performed mining. Equipment leases have not been considered in this FS.
The initial capital cost estimate is based on the execution plans described in this Study. Sunk costs and owner’s reserve were not considered in the initial capital estimate.
The sustaining capital estimate is based on waste development, mining equipment acquisition and rebuilding, and mining infrastructure installations as defined by the mine plan during operations.
Operating Cost Estimation
The average life-of-mine (LOM) unit operating cost is estimated at $96.28/t processed and is summarized in Table 7. The mine will use a peak total workforce of approximately 1,333 people including all contract labour.

(⁰): George Ore Hauling quantities amount to 3.4Mt LOM at $19.35/t hauled.
Note 1: Excludes pre-production mining activities.
Mineral Resource Estimate
The Mineral Resource estimate is based on geologic block models that incorporated:
- 896 drill holes (for a total of 244,853 m and 124,274 assays) at the Goose Site on the Llama , Umwelt , Echo , and Goose Main deposits; and
- 770 drill holes (for a total of 139,695 m and 54,273 assays) at the George Site on the LCPN LCPS LOC1, Loc2, GH, and Slave deposits.
Mineralized domains were constructed to constrain the estimates using a 0.3 g/t Au threshold for both the Goose and George sites. Capping was employed where required, and varied by deposit. Data density allowed for Indicated and Inferred Resources to be classified at all deposits, with Measured Resources also classified at the Goose Main, Llama, and Umwelt deposits.
Table 8: Summary of Estimated Mineral Resources (as of October 21, 2014)
|Classification||Tonnes (kt)||Au (g/t)||Metal (koz Au)|
|Measured and Indicated||28,242||5.87||5,333|
Ms. D. Nussipakynova, P.Geo. and Dr. A. Fowler, Ph.D., MAusIMM, CP (Geo), both from AMC and Qualified Persons under NI 43-101, take responsibility for the Mineral Resource estimates.
Open pit Mineral Resources are constrained by an optimized pit shell at a gold price of US$1,500 oz. The cut-off grade applied to the open pit Resources is 1.0 g/t Au.
The underground cut-off grade is 4.0 g/t Au for all George Mineral Resources (LCPN, LCPS, LOC1, LOC2, GH, and Slave), 3.5 g/t Au for Goose Main, Echo, and Llama, and 4.5 g/t for the Umwelt deposit.
The George Mineral Resources were estimated within mineral domains expanded to a minimum width of 2 m for the underground Mineral Resources.
Drilling results up to December 31, 2013 are included, except for Echo (July 4, 2014) and LOC1 and LOC2 (July 21, 2014).
The numbers might not add due to rounding.
Measured and Indicated Mineral Resources are inclusive of Mineral Reserves
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
Mineral Reserve Estimate
The Mineral Reserve estimate for the Project is based on the Mineral Resource estimate completed by AMC with an effective date of October 21, 2014.
The Mineral Reserves were developed by examining each deposit to determine the optimum practical mining method. Cut-off grades (COGs) were then determined based on appropriate mine design criteria and the adopted mining method. Four mining methods were chosen: shovel-and-truck open pit mining, underground mining using post pillar cut-and-fill (PPCF), drift and fill (DF), and longitudinal open stoping (LOS).
Table 9: Summary of Estimated Mineral Reserves (as of April 21, 2015)
|Area||Classification||Tonnes (kt)||Au (g/t)||Contained Au (koz)|
|Total Open Pit||Proven||7,902||5.35||1,360|
|Total Back River Property||Proven||8,158||5.36||1,405|
- A gold price of US$1,250/oz is assumed.
- An exchange rate of CDN$1.05 to US$1.00 is assumed.
- The numbers might not add due to rounding.
- Notes for open pit:
A COG of 1.39 g/t was used for the Umwelt Open Pit Mineral Reserve estimate.
A COG of 1.41 g/t was used for the Llama Open Pit Mineral Reserve estimate.
A COG of 1.37 g/t was used for the Goose Main Open Pit Mineral Reserve estimate.
A COG of 1.30 g/t was used for the Echo Open Pit Mineral Reserve estimate.
A COG of 1.90 g/t was used for the LCPS Open Pit Mineral Reserve estimate.
A COG of 1.90 g/t was used for the LCPN Open Pit Mineral Reserve estimate.
A COG of 1.87 g/t was used for the LOC1 Open Pit Mineral Reserve estimate.
A COG of 1.89 g/t was used for the LOC2 Open Pit Mineral Reserve estimate.
Notes for underground:
Dilution and recovery factors are applied as per underground mining method.
A COG of 3.18 g/t was used for the Umwelt underground Mineral Reserve estimate.
A COG of 3.80 g/t was used for the Llama underground Mineral Reserve estimate.
A COG of 3.77 g/t was used for the Goose Main underground Mineral Reserve estimate.
A COG of 3.21 g/t was used for the Echo underground Mineral Reserve estimate.
A COG of 4.02 g/t was used for the LCPS underground Mineral Reserve estimate.
A COG of 3.84 g/t was used for the Locale 1 underground Mineral Reserve estimate.
A COG of 4.09 g/t was used for the Locale 2 underground Mineral Reserve estimate.
Both the Mineral Resource and Mineral Reserve estimations take into consideration on-site operating costs (e.g., mining, processing, site services, freight, general and administration), geotechnical analysis for both open pit wall angles and underground stope size, metallurgical recoveries, and selling costs. In addition, the Mineral Reserves incorporate allowances for mining recovery and dilution, and overall economic viability.
Project Execution and Development
The Project execution plan and general Project development schedule considers the seasonality of transporting freight. The procurement and staging of equipment, materials, and fuel at the respective east and west coast ports needs to take place at least 8-12 months before anticipated arrival at the Goose and George sites. The MLA is planned to receive sea-lift materials in the summer open-water period of August and September. Materials would then be stored until the winter ice road is operational from between January and April. Fixed-wing aircraft landing at Goose Site will support construction and operations activities by delivering passengers and select equipment and materials.

Back River Reduced CAPEX Opportunity
While the Back River FS offers a strong economic result and is the preferred path to production, it is recognized that financing such a project in current market conditions would be challenging.
A unique feature of the Back River Project is the multitude of open pit and underground resources along with variability of resource grades. This situation offers the optionality to selectively mine and process higher grade zones through the utilization of a higher cutoff grade. Therefore, in connection with the FS, a conceptual opportunity was identified for a smaller throughput, higher grade, lower CAPEX start-up operation.
This high level, while very preliminary and not to be relied upon, showed the potential for project scalability targeting a CAPEX in the $300 million range and production of approximately 150,000 — 200,000 ounces of gold annually for over 10 years.
Work on an alternative reduced CAPEX scenario has not been included as part of the FS other than in the recommendations and Opportunities section of the 43-101. JDS has recommended further work be undertaken in order to evaluate a potentially more easily financeable project in the current capital markets environment.
New and modified mining projects in Nunavut are subject to environmental assessment (“EA”) and review prior to certification and issuance of permits to authorize construction and operations. The primary environmental review and approval process applicable to the Project is the territorial EA administered by the Nunavut Impact Review Board (“NIRB”). A Project Certificate, if recommended by NIRB, might be issued by the Minister of Aboriginal Affairs and Northern Development Canada (“AANDC”) at the conclusion of the EA process, which represents government approval and allows the proponent to pursue the necessary regulatory authorizations needed to construct and operate the Project.
In June 2012, Sabina submitted a project description and various applications to the NIRB, Nunavut Water Board, and AANDC. In January 2014, a draft environmental impact statement was submitted to the NIRB. In July 2014, Sabina responded to project information requests, and, in October 2014, Sabina responded to agency technical comments. In November 2014, a week-long technical meeting and a pre-hearing conference were held in Cambridge Bay. A Pre-hearing Conference Decision report was produced based on these meetings with the Government of Canada, the Government of Nunavut, the Government of NWT, the Kitikmeot Inuit Association (“KIA”), and the general public. This document summarizes Sabina’s commitments, and provides further direction, for the content of the 2015 Final Environmental Impact Statement (“FEIS”).
The design of the Project includes a comprehensive water management plan for construction, operations, and closure. All Project components will be decommissioned and reclaimed according to best industry practices, and territorial and federal regulations. The closure plan uses proven practices that include appropriate long-term management of PAG/metal-leaching materials and any affected waters. The objective of final reclamation for the Project is to return the site to a productive condition after mining activities are completed.
Based on the information available and the proposed design, there appears to be no adverse environmental or socio-economic aspects that could limit the development of the Project.
A Technical Report for the Back River FS will be filed on SEDAR (www.sedar.com) within 45 days of this news release in accordance with National Instrument 43-101. Readers are encouraged to read the technical report once filed, including the qualifications and assumptions on which it is based.
