Clifton Star Announces Positive PEA Study on Duparquet Project

QUEBEC CITY, QUEBEC--(Marketwire - Jan. 15, 2013) - Clifton Star Resources Inc. ("Clifton Star" or "The Corporation") (TSX VENTURE:CFO)(FRANKFURT:C3T) is pleased to report that it has received the results of a positive Preliminary Economic Assessment Study ("PEA") on the Duparquet Project. The PEA Study was prepared by InnoveExplo with contributions from Bateman Engineering (Bateman), Stavibel, a subsidiary of SNC-Lavalin, Dreisinger Consulting, and P.J. Lafleur GeoConseil, in accordance with the Standards of Disclosure for Mineral Projects as defined by National Instrument 43-101 ("NI 43-101"). The contribution of each party is noted below under the section "Qualified Persons". The complete study will be filed on the Corporation's website and on SEDAR within 45 days.

The PEA Study was prepared as an open pit mining project relating solely to the mineral resources located on the Duparquet Property, situated in north-western Quebec, 50 kilometres by road to the north of the mining town of Rouyn-Noranda. The pre-production capital costs and sustaining costs for the Duparquet Project are estimated, respectively, at $370 million and $144 million, excluding $22.6 million for closure costs. The average operating cash cost is estimated at US$726 per ounce of gold.

The financial analysis, using a gold price of US$1,472 per ounce, indicates a pre-tax net present value ("NPV") (using a 5 % discount rate) of $382 million, with a pre-tax internal rate of return ("IRR") of 19.5% and a payback period of 4.2 years. Sensitivity analysis indicates a pre-tax NPV (5% discount rate) of $621 million, with an IRR of 27.6%, and a payback period of 2.95 years at a gold price of US$1,700 per ounce.

A new NI 43-101 resource estimate was prepared for the PEA by InnovExplo (see hereafter), and was used to develop an open-pit mining plan resulting in 1.67 million ounces of gold. The mine plan was designed for a nominal 8,000 tonne-per-day operation, with an average stripping ratio of 5.52 and a life of mine (LOM) of 16 years. Average yearly gold production for the first 5 years is 144,800 ounces, and the first 10 years average is 132,200 ounces. For the LOM a yearly average of 104,400 gold ounces is predicted.

All mineralized material classified as Measured and Indicated (71%) and Inferred (29%) Mineral Resources was considered in the optimization and mine plan. The PEA is preliminary in nature, it includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be characterized as mineral reserves, and there is no certainty that the PEA will be realized.

Mining plan

The Duparquet Project has been designed as an open pit mine with a planned ore production rate of 2,686,400 tonnes per year, or 8,000 tpd of mineralized material (availability is set at 92% or 336 days per year), except for the first year of production, which has been modeled at 75% of capacity, to reflect a ramp-up period. The mining plan is supplemented by the 4.1Mt of tailings available.

Due to the proximity to the town of Duparquet, adjacent and to the south of the mining concessions of the Duparquet Project, it was decided to select a mining plan that does not include moving any houses, town or provincial infrastructures. Click here to See Figure 1. The mine scenario would therefore be more socially acceptable, but has the effect of leaving in-situ parts of the deposit. These untouched portions may be recovered eventually. It is anticipated that permitting and construction of the mine would take approximately three years.

Pit optimization was performed by Pierre-Jean Lafleur and InnovExplo using Whittle software from Geovia (previously Gemcom). The optimized pit shell was generated by a Lerchs-Grossmann pit optimizer algorithm, using the following cost and economic parameters.

Description Cost
Working days (mill/mine) 336/360
Selling price (in Canadian dollars) 1,449 $/oz
Refinery cost 5 $/oz
Production 2,686,400 t/year
8,000 t/day
Mining recovery 90.9 %
Dilution 10 %
General administration 4.18 $/t
Overburden Removal 2 $/t
Mining cost (ore and waste) 2.40 $/t
Water management 0.24 $/t
Process recovery of mineralized material 93.9 %
Process cost; mineralized material 13.46 $/t
Transportation cost from stockpile to mill 0.25 $/t
Process recovery of tailing 83.9 %
Process cost; tailings (including 0.30$/t transportation to mill) 11.07 $/t

The contained Measured and Indicated resources in the selected pit are 23.10 Mt at a grade of 1.56g/t and Inferred Resources of 14.45 Mt at a grade of 1.10g/t. Dilution was estimated at 10% and mining recovery at 90.9%. Measured and Indicated resources represent 69.2 % of the resources in the selected pit and 71.2% considering the tailings.

The milling circuit includes crushing, grinding, gravity, flotation, pressure oxidation and carbon-in-pulp leaching (CIP). Metallurgical test work indicates that the use of the pressure oxidation technology prior to leaching improves the overall average gold recoveries to 93.2 % (93.9 % for mineralized material and 83.9 % for tailings) based on tests carried out at SGS Lakefield. Milling costs were estimated at $13.46/t processed. Tailings milling costs were estimated at $11.07/t.

The total resource potentially amenable to mining considered in the open-pit mine plan allows for the recovery of 1.67 M ounces of gold. The mining plan produced by InnovExplo includes 19.3 MT of mineralized material at an average grade of 1.88 g/t of gold, the stockpiling and milling of 18.2 MT of mineralized material at an average grade of 0.86 g/t of gold and the excavation and milling of 4.1 MT of tailings at a grade of 0.94 g/t of gold, in an optimized mining schedule that will extend over 16 years. The first 10 years will mostly involve open pit mining and milling of ROM. The last 6 years will only involve milling of accumulated stockpiles and of the tailings.

The mining schedule will require the removal of 37.5 million tonnes of mineralized material and 207.3 million tonnes of waste rock, resulting in a LOM strip ratio of 5.52 to 1. The overburden consists of 14.8 Mt, and will be put aside for reclamation work. Accounting for the overburden, the LOM strip ratio is 5.92 to 1.

Conventional open pit mining methods will be used, requiring a fleet of 136 tonne capacity off-road haul trucks, hydraulic excavators (16.5 m3), production drills and various ancillary equipment. Mine operations were designed to support an average daily production rate of 70,000 tonnes, including overburden.

The pits were designed with a double benching arrangement, and include an 8.5 meter geotechnical safety berm at every 20 meters in vertical height. Based on preliminary geotechnical review of the core, the recommended inter-ramp pit slope will average 52 degrees.

New NI 43-101 Resources estimate for the Duparquet Project:

A new resources estimate was prepared by InnovExplo and is included in the PEA report. The block model was prepared by using 3D block modelling and inverse distance squared interpolation method. A total of 35 new 2012 drill holes, 8 existing drill holes that have been extended to depth, a series of 47 "re-sampled" holes and 35 pre-2008 drill holes were added into the previously compiled and verified master database used in the NI 43-101 mineral resources estimate of July 2012. The updated master resource database currently has a total of 739 diamond drill holes, accounting for a total of 231,355 meters of drilling in length with 147,400 sample intervals. It also includes 2,371 samples coming from 892 surface channel samples, equivalent to 1,827 meters. The database includes the drilling and assay results up to the cut-off date of September 2012. The purpose of the 2012 drilling was mainly to increase the continuity and quality of the resources between surface and 350 meters depth. InnovExplo states that excellent potential exists to further increase the resources of the mineralized zones towards the east and at depth by drilling.

InnovExplo has estimated the total resources for the Duparquet Project(1) as follow:

  • The overall Measured and Indicated resources total 46,091,600 t at a grade of 1.62g/t for 2,404,924 contained ounces of gold. This is a 40% increase for the category, compared to the NI 43-101 report of July 2012. The overall Inferred Resources total 32,146,300 t at a grade of 1.43g/t, for 1,477,164 ounces of gold.

  • The In-Pit resources in the Measured and Indicated category are 38,020,200 t at a grade of 1.59 g/t, for 1,943,027 contained gold ounces. In the Inferred category, they are 26,739,600 t at a grade of 1.15 g/t, for 991,494 contained gold ounces.

  • Underground resources in the Measured and Indicated categories are 3,946,800 t at a grade of 2.66 g/t, for 337,403 contained gold ounces. In the Inferred category the total is 5,406,700 t at a grade of 2.79 g/t, for 485,670 contained gold ounces.

  • Tailings total 4,124,600 t at a grade of 0.94 g/t, all in the Measured and Indicated categories, for 124,495 contained gold ounces.

Metallurgy and Processing

Gold mineralization of the Duparquet Project is associated with disseminated sulphides, mostly pyrite and lesser arsenopyrite. As the material is refractory, the selection of an oxidation method before the cyanidation of a flotation concentrate became necessary to improve and optimize the level of gold recovery. The consistency of the results obtained, combined with historical use of this technology elsewhere in the world over the last 30 years, led to the selection of the conventional pressure oxidation (POX) technology utilizing an autoclave as the preferred method of oxidation for the Duparquet Project.

This process uses sulphide oxidation at high pressure and temperatures, thereby speeding up the kinetics and allowing the reaction to be self-sustaining. The processing facilities will be located at Duparquet and include: crushing, grinding, gravity, flotation, pressure oxidation and carbon-in-pulp leaching (CIP). Metallurgical test work performed by SGS Lakefield indicates that the use of the pressure oxidation circuit prior to leaching improves the projected overall gold recoveries to 93.9 % for the mineralized material and 83.9 % for the tailings.

Tailings Ponds

The PEA Study includes two distinct tailings impoundments. The preliminary designs for the tailings impoundments were prepared by Stavibel. (Click here to See Figure 1) Eighty two percent (82%) of the tailings containing low sulphide, low arsenic and no cyanide will be stored in a flotation thickened tailings pond that will ultimately represent an area of 340 hectares. The remaining 18% of the tailings, coming from the autoclave circuit, and containing a higher concentration of arsenic and sulphides, will be stored in a specifically designed impoundment, which will ultimately cover 107 hectares.

Additional Technical Information Related to the PEA Study

The Duparquet Property is comprised of the Beattie, Donchester, Central Duparquet and Dumico properties. The historic Beattie and Donchester underground production totalled 1.5M ounces of gold. The historical Beattie Mine site surface area will be cleaned up and the current buildings demolished and removed prior to the development of the open pit mining. The cost estimation of this work was estimated at $13M by Stavibel, and is part of the environmental capital costs.

Proposed Surface Infrastructure

The proposed mine infrastructure incorporates the following: (Click here to See Figure 1)

  • Crusher and mill complex, including a crushing, grinding, gravity, flotation, pressure oxidation, leaching circuit (CIP) and a refinery;

  • Office and garage and associated services buildings;

  • New electrical main line from the Hydro Quebec grid, site substation and site electrical distribution installations;

  • Pit dewatering system, surface water management and water treatment plant;

  • Access roads to the site and on site;

The waste rock dump will cover 160 hectares and reach a maximum height of 140 metres. The waste rock is not considered to be acid-generating or potentially metal leaching.

The low grade pile will cover 18 ha of land and will be built on impervious ground cover, and will be surrounded by a collection ditch to recover run-off water and to treat the water, if needed.

Mine Closure

Mine closure costs are estimated by Stavibel at $22.6 million. Of this amount, an estimated $15.8 million would have to be deposited in accordance with applicable legislation which may vary upon approval of production permits. The closure costs are spread out over the LOM, in the cash-flow calculation, but are excluded from capital or sustaining capital costs.

Wherever practical, a progressive reclamation approach is recommended, since the tailing ponds will be built in stages. At Duparquet, the overburden disposal area will be reclaimed and used as capping material to re-vegetate waste rock and tailings disposal sites.

Capital and Sustaining Capital Costs Estimates

The PEA Study is based on capital pricing as of the first quarter 2012. The capital costs include various added contingencies depending on the sectors. The pre-production capital costs are estimated at $370.2 million and include $132 million for contingencies and indirect costs. Indirect costs (owner's costs, Engineering, Procurement and Construction Management ("EPCM") and detailed engineering) of 15 % have been applied on the process plant and 17 % to the other surface infrastructures. Contingencies of 15% have been applied on the mill and infrastructures, and 25% have been applied on the waste rock and tailings impoundments. Average contingency for all environmental items is 20.5%. Sustaining capital expenditures over the LOM are estimated at $144.7 million, including $29.6 million for the overburden removal during mine life.

Operating Costs

The LOM average operating cash cost is estimated at US$726 per ounce of gold and an average of $29.38/t milled. For the first 10 years, the operating cost will average $36.65 per tonne milled. The average will be $16.62 per tonne milled for the last 6 years, when only milling of the stockpiles and tailings takes place. On the cash flow estimation, mining costs was adjusted at $2.40/t for the mineralized rock and $2.15/t for the waste rock. Overburden removal costs were estimated at $2.00/t.

Financial Analysis

The financial analysis for the Base Case (gold at US$1,472) indicates a pre-tax NPV at a 5% discount rate of $382 million, with an IRR of 19.5% and a payback period of 4.2 years. At a gold price of US$1,700, the pre-tax NPV of the project at a 5% discount rate, is 621M$, the IRR is 27.6%, and the payback period is 2.95 years.

Recommendations of the PEA:

Following the positive outlook of the PEA, InnovExplo recommends that the Duparquet Project be advanced to the next phase, which would consist of the preparation of a Pre-Feasibility Study.

In order to advance to the pre-feasibility stage, additional definition drilling is recommended to continue to upgrade the resource categories.

Additional metallurgical bulk tests are also recommended to further define the flow sheet of the ore treatment, and to also examine the possibility of producing a saleable concentrate. This concentrate could be sold to smelters, thereby eliminating the POX part of the milling, could imply significant Capex and Opex reduction for the project, and increase the rate of returns.

Additional geotechnical and hydrogeological studies should be undertaken for the proposed site buildings, tailing management facility, and to better define and ideally steepening the pit wall slopes from those presented in the report.

As well, Stavibel recommends starting permitting and social outreach to present the project to the communities, while at the same time characterizing fully the mining project environment.

It is recommended that negotiations with Hydro-Quebec be initiated to advance the work for installation of the power line.

The budget for the proposed program is presented in the following table. It covers the period 2013 and 2014, in order to deliver a Pre-Feasibility report in the first quarter of 2014, and to continue community outreach and permitting in 2014.
