VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb 20, 2013) - Northern Freegold Resources Ltd. (TSX VENTURE:NFR)(NFRGF)(8N6.F) is pleased to announce results of a NI 43-101 compliant Preliminary Economic Assessment ("PEA") for the Nucleus and Revenue deposits at the road accessible Freegold Mountain Project, in the Yukon, Canada. The project is 100% owned by Northern Freegold (the "Company").
The PEA was prepared by GeoVector Management Inc. The PEA was prepared as an open pit mining project. The project expects to yield a pre-tax net present value of $614.8 million and an internal rate of return ("IRR") of 23.4% at a 5% discount rate using three year trailing average prices of US $1455 per ounce gold, $3.65 per pound copper, $14 per pound molybdenum1, and $27.55 per ounce silver respectively. At recent prevailing spot commodity prices the pre-tax NPV (5%) and IRR increase to $779.6 million and 29.7% respectively. The results of the PEA demonstrate the potential technical and economic viability of a new gold with copper and molybdenum mine on the property. All $ are Canadian except where indicated.
- Average Life of Mine ("LOM") annual production is forecasted at 150,000 oz gold, 17.3 million lbs copper, 4.2 million lbs molybdenum and 355,000 oz silver;
- First five years average annual gold production exceeds 200,000 oz;
- Average LOM cash cost of gold (net of byproducts) is $399 per oz;
- NPV (5%) $614.8 million pre-tax; IRR 23.4% pre-tax;
- NPV (5%) $357.8 million after-tax; IRR 17.5% after-tax;
- Throughput: 30,000 tonnes per day;
- Strip ratio over LOM 2.03:1;
- Mine life: 11 years;
- Pre-production capital of $499.7 million and Expansion capital of $78.6 million for mill additions in Year 5;
- Payback period from production: 4.2 years;
- At recent prevailing spot metal prices, the project generates a pre-tax NPV (5%) of $779.6 million, IRR of 29.7% and a payback of 3.2 years (see Sensitivity Analysis Table).
The PEA is considered by Northern Freegold as the current optimized development scenario for the Freegold Mountain project based on the existing resources at Nucleus and Revenue. Both the Nucleus and Revenue deposits remain open as to depth and width providing future potential to significantly increase the size of the resource. Exploration data on the property clearly indicates that substantial potential exists for scaling up the project economics, and this upside includes:
- Numerous mineralized showings occur outside the current NI 43-101 resource areas with similar characteristics to Nucleus or Revenue which have seen minimal exploration and have the potential to develop into additional mineral deposits;
- Twelve priority geophysical anomalies associated with significant soil copper and gold geochemical anomalies have been identified for further exploration and have the potential to develop into additional mineral deposits. This includes the 3 kilometre long zone between the Nucleus and Revenue deposits.
"This is a key milestone for Northern Freegold," said John Burges, President & CEO, "this PEA demonstrates robust economics. The phased development with initial production at the Nucleus gold deposit helps to reduce upfront capital. Over 62% of the revenues are from gold production at an operating cost of less than $400 per ounce after byproduct credits. We have successfully grown the Nucleus/Revenue gold resource over 300% over the last four years and on a gold equivalent basis over 700%. Our exploration/drilling discovery costs for the 2012 inaugural Revenue resource were low at ~ $3 per gold ounce and $1 per gold equivalent ounce. There remain significant opportunities to grow the resources adjacent to the conceptual pits and extend the mine life, and there are many other high priority targets on the 10 km geophysical anomaly which have the potential to develop into near surface higher grade deposits."

Financial Assumptions, Results and Sensitivities
For Base Case metal prices the Company used three year trailing averages for gold, copper and silver. A lower long term price for molybdenum was used rather than the current three year trailing average.
|Table 1: Three Year Trailing Averages2|
|Long Term FX Rate C$:US$||1 : 0.98|
|2 For Gold, Copper and Silver|
The financial analysis for the Base Case indicates a pre-tax NPV at a 5% discount rate of $614.8 million, with a 23.4% pre-tax IRR and a payback of 4.2 years. This includes all NSRs. The after-tax NPV at a 5% discount rate is $357.8 million with an IRR of 17.5%. The after-tax analysis assumes 30% Federal and Yukon taxes adjusted for depreciation/allowances together with royalties paid to the Yukon Government. On the Base Case the breakdown of revenues is as follows:
|Table 2: Breakdown of Revenues|
|Metal||Percentage of Revenues|
Sensitivities were run on the Base Case at different discount rates and these are summarized in Table 3 below.
|Table 3: NET PRESENT VALUE ANALYSIS (in $MM)|
|Discount Rate||Base Case||Discount |
Sensitivities were also run on all metal prices. These are summarized in the following table.
|Table 4: Net Present Value Metal Price Sensitivity|
|All Metal |
|All Metal |
|Pre-Tax NPV (5%) ($ millions)||364.3||614.8||866.6|
|After-Tax NPV (5%) ($ millions)||197.2||357.8||513.5|
|Pre-Tax IRR (%)||16.5||23.4||29.9|
|After-Tax IRR (%)||12.2||17.5||22.2|
|Payback Period (years)||5.5||4.2||3.4|
Further sensitivities were run around key revenue and cost variables. These are summarized in the table below:

- Sensitivity analysis is based on the change of gold price only while other metal prices remain at the Base Case.
- Spot prices are quoted as of February 4, 2013: gold $1674/oz, silver $31.76/oz, copper $3.74/lb and molybdenum $11.48/lb using a C$:US$ 1:1 FX rate
- Capital costs include Pre-Production capital of $499.7 million and Expansion capital of $78.6 million.
The PEA incorporates the recent NI 43-101 mineral resource estimates for both the Nucleus and Revenue deposits.
|Table 6: Mineral Resource Estimate for Nucleus Deposit (see news release dated January 9, 2013)|
|Table 7: Mineral Resource Estimate for the Revenue Deposit (see news release dated January 18, 2012)|
- Gold equivalent (AuEq) for the Nucleus Resource is calculated based upon 3 year trailing average prices of US$1,455/oz for gold, US$27.55/oz for silver and US$3.65/lb for copper and assumes metallurgical recoveries of 97% for gold, 51% for silver and 43% for copper (Note:total contained AuEq metal values may not add exactly because of rounding).
- Gold equivalent (AuEq) for the Revenue Resource is calculated based upon prices of US$1,016/oz for gold, US$15.82/oz for silver, US$2.95/lb for copper and US$15.82/lb for molybdenum, and assumes 100% metal recovery with no discount for metallurgical recovery in contained metal figures (Note:total contained AuEq metal values may not add exactly because of rounding.)
- Mineral resources do not demonstrate economic viability, and there is no certainty that these mineral resources will be converted into mineable reserves once economic considerations are applied.
Potentially economic open pit portions of the resources have been calculated with an open pit cut-off grade of approximately 0.25 g/t AuEq. The resulting tonnages and grades for the open pit conceptual mine plan are as follows:
|Table 8: Nucleus In-Pit Resources|
|Table 9: Revenue In-Pit Resources|
Mineral resources are reported in relation to conceptual pit shells. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The Preliminary Economic Assessment is preliminary in nature, and is based, in part, on inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the preliminary assessment will be realized. All figures are rounded to reflect the relative accuracy of the estimate. All composites have been capped where appropriate.
Mining & Processing
The PEA is based on a conventional open pit mining operation and a processing facility of 30,000 tonnes per day. It is envisaged that mining and processing of the Nucleus resource will commence first and that processing of material from the Revenue deposit will commence in year five. Processing of the Nucleus deposit is planned to consist of crushing and grinding, gravity recovery of coarse gold followed by cyanidation and solvent extraction, utilizing the SART process, to recover gold, silver and copper. The SART process (sulphidization-acidification-recycle-thickening), developed jointly by SGS Lakefield and Teck Corporation, can remove the metallurgical interference of leachable copper and zinc, and regenerate cyanide so that it can be recycled to the gold operation. This is beneficial in two ways; first it lowers the cyanide costs substantially because the cyanide from CN-Cu complexes is reclaimed and reused in the gold circuit and secondly, copper is recovered from solution by electrowinning.
Processing of material from the Revenue deposit will be by conventional crushing, grinding, gravity recovery of gold, flotation of copper and molybdenum concentrates, followed by cyanide leach for final gold recovery. The process recovery flowsheet and metal recovery estimates are based on initial metallurgical studies carried out by SGS Canada Inc. in 2012 on representative mineralized composites from both the Revenue and Nucleus deposits (press release September 12 and September 19, 2012). At the assumed processing rate the forecast production is as follows:
|Table 10: Forecast Production|
|Total production, LOM||1,607,891||3,803,412||185,447,207||45,295,027|
|Average annual production||150,270||355,459||17,331,515||4,233,180|
|Mill Grade, LOM (g/t, %)||0.482||2.03||0.090%||0.022%|
|Recovered Grade, LOM (g/t, %)||0.427||1.01||0.072%||0.018%|
|Estimated LOM overall recovery (%)||88.4%||49.6%||80.1%||78.8%|
Roads and Power Access
The Freegold Mountain project is located within the Dawson Range and covers an area in excess of 198 square kilometres (75 square miles). The Nucleus Au-Ag-Cu deposit and the Revenue Cu-Au-Mo-Ag deposit cover approximately 30 square kilometres. The project has significant infrastructure advantages. It is located approximately 200 kilometres northwest of Yukon''s capital and industrial center in Whitehorse. It is road accessible from Whitehorse, along the main Klondike Highway, a paved all-weather highway running from Whitehorse to Carmacks thence along a 70 kilometre government maintained road from Carmacks, called the Freegold Road. This government maintained road currently terminates near the Company''s Revenue camp thus giving the Company full road access. Western Copper and Gold Corporation, recently released its feasibility study (January 7, 2013) on the large Casino copper-gold property, which lies a further 132 kilometres to the west. They propose extending the Freegold Road from Northern Freegold''s property generally following the alignment of the "Casino Trail". Commercial electrical grid power is available at Carmacks. The publicly owned Yukon electricity utility, the Yukon Energy Company ("YEC"), recently built a new 138kv high voltage transmission line along the Klondike Highway from Carmacks to Stewart Crossing linking the north and south electricity grids. The utility also built a spur electrical line extending into the Minto copper mine 30 kilometres north of the Freegold Mountain project which is operated by Capstone Mining Corp. The Company anticipates that YEC will provide grid power to the project by connecting to either existing lines or to proposed lines that YEC anticipates developing. The spur line that will be required is assumed to be approximately 30 km in length. The Company has assumed it will be responsible for the capital for this grid connection.
Infrastructure development is anticipated to include:
- plant site and haul roads;
- mine maintenance garage, warehouse and fuel storage facilities;
- administration buildings, accommodation facilities, and assay lab;
- fresh water supply and sewage treatment;
- two open pits (Nucleus and Revenue);
- waste rock disposal areas;
- tailings pond; and
- power supplied by a 30 kilometre long transmission line connecting to the Yukon power grid.

Pre-Production Costs and Expansion Costs
Total Capital is outlined in Tables 12 and 13 below. Pre-production capital is $499.7 million for the start of production at Nucleus. This is followed by Expansion capital of $78.6 million for mill additions at the start of Revenue production in Year 5 of the mine life which will be funded out of project cashflow. The PEA also assumes LOM Sustaining capital and Mine Closure costs net of salvage values of $90.4 million.
