Raymond Threlkeld, Rainy River's President and CEO, stated: "With the release of the Rainy River Gold Project Feasibility Study, we are transitioning to the mine development stage of Canada's newest gold district. The Feasibility Study outlines an outstanding project, located in one of the best mining jurisdictions in the world, conveniently surrounded by infrastructure, and with tremendous exploration potential.
"By continuing to focus on our strategy of delivering a project with the lowest risk to our shareholders and the strongest internal rate of return, we have developed a plan with high production rates, low cash and "all-in" costs and strong margins.
"Our planned mine production averages 326,000 ounces of gold and 494,000 ounces of silver annually in the first 10 years of the combined open pit and underground operation. Over that period, we will operate at mill head grades of 1.46 grams per tonne of gold and 3.19 grams per tonne of silver, and a low open pit operating strip ratio of 2.8:1, which excludes overburden and capitalized waste.
"The higher grades mined in the open pit and underground will enable the average cash costs in the first five and 10 years to be US$413 and US$468 per ounce of gold including royalties and net of silver credit, respectively, which would place the Rainy River Gold Project in the lowest and second-lowest quartiles for cash costs, respectively, among gold producers worldwide. The after-tax NPV is $931 million with low "all-in" cash costs of US$771 per ounce gold (at US$1,400 per ounce gold, US$25 per ounce silver, including royalties and net of silver credits).
"This mine plan, combined with the exploration potential in our district, makes the Rainy River Gold Project stand out in Canada as a low risk, high return project.
"A prime example of the district potential is our exciting Intrepid Zone, where last week we saw high grade intercepts of almost half an ounce of gold and almost 3 ounces of silver over 9 metres in drill hole NR 131523. The Intrepid Zone, which is not included in the Feasibility Study, exemplifies the potential of the district and is expected to add high quality ounces to an already outstanding Rainy River Gold Project."
Areas of Upside Potential for the Project
- Intrepid Zone integration into the mine plan
- District exploration

Open Pit and Underground Mineral Reserves
The FS mineral reserves are based on the October 2012 resource update (see Rainy River Resources' press release dated October 10, 2012). For the FS, open pit mining dilution and mining recovery are calculated as 9.7% at 0.22 g/t gold and 1.31 g/t silver and 95%, respectively. Approximately 80% of the underground mineral reserves are in long-hole (LH) stopes, with the balance of about 20% of underground reserves in cut-and-fill ("CAF") stopes. Overall, it is estimated that the LH stopes will have approximately 10% dilution grading 1.56 gpt gold and 1.28 gpt silver. Dilution in the CAF areas is estimated to be 9% with a grade of 0.61 gpt gold and 4.16 gpt silver. Underground resources have been calculated assuming a mining recovery of 95%.
The open pit cut-off grade is 0.30 g/t gold-equivalent ("AuEq"), and the underground cut-off grade is 3.5 g/t AuEq. The resulting mineral reserve calculation for the open pit and underground mine plans is shown in Table 2:

Open Pit Reserves have been estimated using a cut-off grade of
0.30 g/t gold-equivalent,
and Underground Reserves have been estimated using a cut-off grade of 3.5 g/t gold-
equivalent. Open Pit Reserves have been estimated using a dilution of 9.7% at 0.22 g/t gold
and 1.31 g/t silver, and Underground Reserves have been estimated using a CAF dilution of
9% at 0.61 g/t gold and 4.16 g/t silver and LH dilution of 10% at 1.56 g/t gold and 1.28 g/t
silver. Open Pit and Underground Reserves have been estimated using a mine recovery of 95%.

The FS assumes the processing of an average 21,000 tonnes per day ("tpd") from a combination of open pit, underground and stockpiled material. The mine schedule contains two years of pre-production and envisions a mine operating life of 16 years, including six years of reclamation from the stockpiles and excluding the pre-production period. Development of the underground operation would start in Year 1 of mine operations and begin producing at full rates by Year 6.
Conventional open pit mining has been chosen as the primary method to extract the Rainy River deposit because of its proximity to surface. The open pit mine production rate is planned to be approximately 21,000 tpd of mill feed material initially, and is gradually reduced to 20,000 tpd once the 1,000 tpd underground operation reaches full production in Year 6. The open pit mining plan is based on a declining cut-off grade strategy, whereby low grade material will be stockpiled near the primary crusher for future processing as needed, at the end of the open-pit and underground mine lives. The objective of this strategy is to obtain a higher average milled grade in the early years in order to maximize the Project's cash flow and economics.
An operating cut-off grade of 0.60 g/t AuEq is applied initially, dropping to 0.45 g/t AuEq in the final years. During open pit operations, material with grade below the operating cut-off grade and at or above 0.30 g/t AuEq is stockpiled near the primary crusher for processing in the last six years. The stockpiled material totals 43 million tonnes ("Mt") at 0.37 g/t Au and 1.97 g/t Ag, and is reclaimed and processed using existing mine equipment after the open pit is exhausted.
The primary mine fleet for the open pit consists of three 28-cubic metre hydraulic shovels, one 15 cubic-metre wheel loader, up to 19 haul trucks (226-tonne-class) and a fleet of support equipment. Initial production drilling will be carried out by a fleet of up to 3 diesel powered track-mounted (DTH) drills. Operating bench heights of 10 metres have been planned for mining operations. Over the life of the mine, a total of 350.6 Mt of waste rock and 80.0 Mt of overburden will be moved. It is anticipated that all overburden will be removed within the first seven years of mine operations.
Waste rock-to-mill-feed operating strip ratios average 2.8 during the first ten years of operations, net of the capitalization of waste material costs. Waste material totalling 32.6 million tonnes ($62.7 million) is excluded from operating expenses and capitalized during the mine life. Mined waste and overburden will be stored in nearby stockpiles or used in dike construction activities associated with the tailings management area.
At the peak of open pit mining (Year 7), a workforce of approximately 299 persons (staff and hourly employees) will be required.
For the underground mine, LH and CAF mining methods are proposed in a ratio of approximately 80:20 by reserves. LH mining will mainly follow a traditional transverse primary-secondary pyramid sequence, using cemented rockfill ("CRF") in the primary stopes and unconsolidated rockfill ("RF") in the secondary stopes. There are minor amounts of longitudinal stoping that will use CRF. The LH stopes are designed with a 25-metre sublevel interval and a hanging wall dip of 60 degrees. The primary stopes are designed to be an average of 10 metres transverse width (across strike) by 10 metres wide (along strike), and the secondary stopes are designed to be 10 metres transverse width by 20 metres wide.
The CAF mining method is proposed in shallower dipping areas that are above the cut-off grade. This method involves mining 5-metre lifts from the bottom up; the lowest lift of a mining zone is mined first. Once complete, this lift is backfilled with unconsolidated rockfill and then the next 5-metre lift above the backfill is mined.
The mining areas are accessed by a main ramp that is 6.0 metres wide by 5.5 metres high with an average gradient of 15%. The underground mine will require main ramps, footwall accesses for LH stopes, and the infrastructure required to support mining activities such as a small underground shop, sumps, and ventilation drifts and raises. Mined waste will either be used as backfill, when possible, or hauled to the waste storage facility at surface. It is estimated that approximately 50% of the underground waste will remain underground as backfill.
The underground mine production rate is estimated to average 1,000 tpd. A fleet of 5.4 cubic-metre load-haul-dumps ("LHDs") and 27 cubic-metre trucks has been selected as the primary underground production equipment. At peak operation, the underground will have approximately 42 pieces of mobile equipment (including production, development and support equipment) and have a ventilation capacity of approximately 350 m3 per second.
At peak operation, the underground will require a workforce of 187 persons (staff, hourly and contract employees).
Both mine areas will deliver material to a central gyratory crusher for primary reduction and delivery to the processing plant.
Metallurgy and Processing
Metallurgical testing has been conducted over a period of almost three years at SGS Canada Inc. in Lakefield, Ontario. Based on the results, BBA has developed a conventional flow sheet including:
- primary crushing and grinding;
- gravity recovery;
- whole-ore leaching followed by a carbon-in-pulp circuit;
- electro-winning and smelting to produce gold doré; and
- a cyanide destruction circuit.
Major equipment for the processing facility includes a 54'' x 75" gyratory crusher, a 36' by 20', 15 MW dual pinion drive semi-autogenous grind ("SAG") mill and a 26' by 40.5', 15 megawatt ("MW") dual-pinion drive ball mill. Mill feed will be ground to a P80 size of 75 microns before entering a leaching circuit for final metal recovery. Equipment has been sized for the 80th percentile of expected ore hardness. The average leach time is 30 hours.
Metallurgical recoveries for gold and silver over the life of the mine are expected to average 90.4% and 64.1%, respectively. One tailings pond is envisioned, and will be located approximately three kilometres northwest of the plant.
It is estimated that 89 people (staff and hourly employees) will be required for the process plant operations.
The RRGP benefits from world-class infrastructure, services and available labour in the immediate area. The project site is located only 65 km from the town of Fort Frances (population 8,000) and is accessible year-round by a network of sealed provincial highways.
Infrastructure is anticipated to include:
- Plant site and haul roads, gate house, parking, bus station and weigh station;
- Separate administration building, mine office and process building;
- Assay lab;
- Mine maintenance garage, warehouse;
- Fuel storage facilities;
- Fresh water supply and fire protection;
- Sewage treatment;
- One tailings management facility;
- Two mine rock overburden/rock stockpiles;
- Various water management ponds;
- Power to the project supplied by a new 17 km long 230-kV transmission line connecting to the provincial power grid, with the total power draw expected to be 57 MW.
- Highway 600 realignment, east access road.

In anticipation of future project permitting, the Company has been working closely with both Federal and Provincial regulatory agencies for several years. Environmental baseline studies were initiated in 2008 and have been followed by extensive annual regional field assessments. Recent milestones have included the acceptance of the Mine Project Description by the Canadian Environmental Assessment Agency as well as the submission of the Provincial Terms of Reference to the Ontario Ministry of Environment. Additionally, the Rainy River Gold Project was selected by the Federal/Provincial Regulatory Reform Working Group to receive enhanced project alignment considerations and involvement from senior government executives and Ministers thereby providing direct support towards an efficient and effective project review.
The Company remains an active member of the local community, supporting a wide variety of community events and training programs. Regular public information meetings and a quarterly community newsletter combined with site tours are some of the ways in which the Company continues to engage and inform the local population as to the Project's progress. These efforts will be amplified and expanded further, in tandem with the release of the Mine Environmental Assessment report during the latter half of 2013.
The Company also continues to work closely with our Aboriginal partners in support of project permitting. Through regular communications and the completion of various agreements, a framework supporting anticipated mine operations has been well advanced.
The peak construction workforce would total 405 during the 23-month construction period. Employment levels at the RRGP during operations would vary according to production requirements, but would peak at approximately 601 persons, including 89 employees in the process plant, 26 employees in General and Administrative roles, 299 employees in the open pit mine and 187 employees in the underground mine.
The first five years of mining yields cash costs (including royalties and net of silver credits) of US$413 per ounce of gold, placing RRGP in the lowest quartile of cash costs for global gold projects, based on published industry cost curves. In years 1 - 10, cash costs average US$468 per ounce of gold, placing the RRGP within the second-lowest quartile of cash costs for global gold projects. Life-of-mine cash costs, net of silver credits, after the processing of low-grade stockpiles in years 11 to 16, are calculated to be US$544 per ounce of gold. This life-of-mine average places the project within the second-lowest quartile of global gold projects, based on published industry cost curves (Brook Hunt, 2017 Cash Cost Curve).
On an "all-in" cost basis, which includes all cash costs, pre-production capital and sustaining capital costs, the Rainy River Gold Project's all-in costs are approximately US$771 per ounce of gold in the first 10 years and US$861 for the life-of-mine, (including royalties and net of silver credits).
Production volumes and cash costs are shown in Tables 6(a) and (b) and 7 below.

This new release uses the terms "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources". The Company advises readers that these terms are defined in accordance with Canadian regulations NI 43-101. The United States Securities and Exchange Commission does not recognize mineral resources. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted in to reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except for a Preliminary Assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
Cash cost per ounce, all-in costs, costs per tonne milled and cost per tonne mined have no standardized meaning under IFRS.
Cash cost per ounce figures, also known as "total cash costs" per ounce figures are calculated in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading global gold producers. The Gold Institute ceased operations in 2002, but the standard is widely accepted as the standard of reporting cash costs of production in the global industry. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Total cash costs include mine site operating costs such as mining, processing, administration, royalties and production taxes, but excludes amortization, reclamation, capital and exploration costs. Total cash costs are reduced by silver revenue and then divided by ounces sold to arrive at the total cash costs per ounce sold. The measure, along with sales, is considered to be a key indicator of a company's ability to generate operating earnings and cash flow from its mining operations.

About Rainy River
Rainy River Resources Ltd. is a Canadian precious metals exploration company whose key asset is the Rainy River Gold Project, a large gold system centred in Richardson Township (part of Chapple Township). As at December 31, 2012, the Company had approximately $102 million in cash and cash equivalents, and it remains well funded for its ongoing activities, including: 1) commencement of detailed engineering work and ongoing permitting and environmental assessment work; 2) continuing to grow the existing resource through exploration; 3) conducting a condemnation program in areas identified for potential mine facilities; and 4) continuing regional exploration. RRGP is very well located in northwestern Ontario. It is accessed by a network of roads and is close to hydro-electric infrastructure. The Rainy River district has a skilled labour force and is one of the lowest-cost areas for mineral exploration and development in Canada. Ontario has low political risk and, according to the annual Fraser Institute global survey of the mining industry, has consistently ranked as one of the top jurisdictions embracing mineral development.
