Aurizon Receives Results of Feasibility Study for Joanna's Hosco Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 5, 2012) - Aurizon Mines Ltd. (TSX:ARZ)(NYSE MKT:AZK)(NYSE Amex:AZK) is pleased to report that is has received the results of a positive Feasibility Study which has established in-pit mineral reserves of 1.66 million ounces of gold in the Hosco deposit that forms part of its 100% owned Joanna project. The Feasibility Study was prepared by BBA Inc. of Montreal, ("BBA") with contributions from other engineering firms and consultants, in accordance with the Standards of Disclosure for Mineral Projects as defined by National Instrument 43-101 ("NI 43-101").

"The Joanna property has provided significant exploration success for Aurizon and the results of the Feasibility Study has realized a 67% increase in Proven and Probable In-Pit Mineral Reserves at the Hosco deposit compared to the 2009 pre-feasibility study," said George Paspalas, President and Chief Executive Officer. "The Company has also encountered follow-up exploration success at the Heva deposit and the Hosco West Extension areas, also on the Joanna property. Whilst the Feasibility Study on the Hosco deposit generates a positive return at three-year trailing average gold prices, we believe that it is prudent, in terms of capital allocation, to defer development and permitting of the Hosco deposit and continue to pursue exploration of these areas, which if successful, could lead to a staged and perhaps more financially beneficial development strategy at Joanna."

"The opportunity at Heva lies in the fact that our early drilling is indicating higher grade ore potential than at Hosco and initial metallurgy has returned very good gold recoveries using conventional cyanidation," continued George Paspalas. "The Hosco West Extension area has identified refractory mineralization that is significantly higher grade than the average grade in the conceptual Hosco pit. The Company intends to spend an additional $4.2 million to continue the drilling in these areas. We remain committed to growing the Company by pursuing opportunities that would be accretive to shareholder value."

The Feasibility Study was prepared as an open pit mining project relating solely to the mineral reserves located on the Hosco deposit. The Hosco deposit forms part of the Joanna Project which is located in pro-mining north-western Quebec, 20 kilometres east of the town of Rouyn-Noranda. The in-pit mineral reserves were estimated at a cut-off grade of 0.5 g/t for a total diluted proven and probable reserve estimate of 41.1 million tonnes at 1.26 grams/tonne representing 1.66 million ounces of gold. The mine plan was designed for a 8,500 tonnes per day operation, with an average stripping ratio of 4.49 to 1 and a life of mine of 13.4 years.

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 gold recoveries to 87.5%. The study provides for the low sulphide tailings, without cyanide, to be stored in a flotation thickened tailings pond and the tailings from the autoclave circuit would be stored in a specifically designed impoundment.

The pre-production capital costs and sustaining costs for the Hosco deposit are estimated, respectively, at $422 million and $97 million. The average operating cash cost is estimated at US$716 per ounce of gold and $25.32 per tonne milled. The financial analysis, using a price of gold of US$1,350 per ounce, indicates a pre-tax net present value ("NPV") (using a 5% discount rate) of $112 million with a pre-tax internal rate of return ("IRR") of 8.7% and a payback period of 8.2 years. On an after tax basis, Aurizon estimates that the IRR is 6.5%.

All other information previously released on Joanna is also available on Aurizon's website at www.aurizon.com.

Additional Technical Information Related to the Feasibility Study

The Joanna Property is comprised of 5 sectors and 156 claims covering 4,294.1 hectares. The Hosco sector represents the core of the Feasibility Study and the other sectors are Heva, Alexandria, Henriksen and Aurizon.

  • The project is located along a prolific geological belt, the Abitibi gold belt and, more specifically, along the Cadillac fault which hosts several multi-million ounces deposits like Noranda, Doyon-Laronde, Malartic and Val-d'Or camps.
  • A pool of experienced workers and suppliers are available from the city of Rouyn-Noranda and Val-d'Or.
  • The proximity of the Casa Berardi Mine as well as the Administration and Technical Office in Val-d'Or is anticipated to create positive synergies with Joanna.

Geology

Mineralization at Joanna is closely related to the east-west Cadillac fault and forms a 200 metre wide corridor composed of different mineralized lenses parallel to the fault, dipping 55 degrees to the north. Mineralization takes the form of a few millimetres to a 15 centimetre-wide quartz vein network inside the altered sediment rock with finely-disseminated sulphides. Mineralization has been defined and correlated based on altered mineral assemblages (biotite, tremolite, carbonates, muscovite, tourmaline, chlorite), quartz textures, deformation features and sulphides types (pyrrhotite and arsenopyrite).

At Hosco, mineralization is located within three main lenses, one located north of the fault and two at the southern side of the fault. Each lens shows a thickness of between 15 and 60 metres and a variable lateral extension of between 300 and 700 metres.

Mineral Reserves and Resources

The in-pit mineral reserves were estimated within a detailed engineered pit design by using the measured and indicated resources at a cut-off grade of 0.5 g/t. The optimized pit shell was generated using the Lerchs-Grossmann pit optimizer algorithm using the cost and economic parameters estimated by BBA.

Mining and Production

The mine plan completed by BBA includes 41.1 million tonnes of ore at 1.26 grams of gold per tonne and requires the removal of 22.3 million tonnes of overburden and 162.3 million tonnes of waste rock resulting in a life-of-mine strip ratio of 4.49 to 1. The overburden consists of silt and clay and varies in thickness between 6 and 15 metres. It is planned that the overburden will be removed during winter seasons.

It is anticipated that permitting and construction of the Mine would take approximately 3 years.

Total gold production over a 13.4 year mine life is estimated at 1.45 million ounces averaging 110,000 ounces per year.

Conventional open pit mining methods will be used requiring a fleet of 100 ton class and smaller haul trucks, hydraulic excavators (10 m3), production drills and various ancillary equipment. Mine operations were designed to support an average daily production rate of 8,500 tonnes. Initial production will start from a smaller pit and will be extended in two additional pushbacks; mining of the West Hosco pit is expected to begin in year 4.

The pits were designed with a triple benching arrangement and include a 15 metre geotechnical safety berm at every 120 metre vertical height. Based on the results of rock mechanic studies by Golder Associates, the recommended inter-ramp pit slope will be 53° for the hanging wall (north), 49° for the footwall (south) as well as both east and west sectors.

Metallurgy and Processing

Gold mineralization in the Hosco Deposit is associated with disseminated sulphides, mostly arsenopyrite and pyrohotite. As the material is partially 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 at the pilot-plant level, combined with higher recoveries, led to the selection of the conventional pressure oxidation technology utilizing an autoclave as the preferred method of oxidation for the Hosco ore.

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 Joanna and include: crushing, grinding, gravity, flotation, pressure oxidation and carbon-in-pulp leaching (CIP). Metallurgical test work performed by Sherritt Technologies indicates that the use of the pressure oxidation circuit prior to leaching improves the projected overall gold recoveries to 87.5%.

Milling Process Crushing, grinding, gravity, flotation, pressure oxidation and leaching
Milling rate 8,500 tonnes per day
Average recoveries (life of mine) 87.5%
Tailings ponds Neutral (no cyanide - low sulphide): 95% of tonnage
Pressure Oxidation (POX) (high arsenic (As) - acid drainage potential):
5% of tonnage

Tailings Ponds

The Feasibility Study includes two distinct tailings impoundments which cover 290 hectares. Ninety-five percent (95%) of the tailings containing low sulphide, low arsenic and no cyanide will be stored in a flotation thickened tailings pond. The remaining 5%, coming from the autoclave circuit, and containing a high concentration of arsenic and sulphides, will be stored in a specifically designed impoundment.

Proposed Surface Infrastructure

The proposed mine infrastructure incorporates the following:

  • A crusher and a mill complex, including a grinding, gravity, flotation, pressure oxidation, leaching circuit (CIP) and a refinery;
  • A garage complex and associated services building and administration offices;
  • Electrical distribution installations;
  • Pit dewatering system, surface water management and treatment;
  • Access road to the site from Highway 117;
  • The waste dumps will cover 192 hectares and reach a maximum height of 70 metres. Most of the waste rock (85 - 88%) that is not considered to be acid-generating or potentially metal leaching will be stockpiled in the main waste rock pile. The remaining 12 - 15% of the waste rock, which has a higher percentage of arsenic and nickel but is not acid generating, will be stored in a separate, fully-lined waste rock pile. Both stockpiles will be surrounded by collection ditches to recover run-off water;
  • Top soil will be stockpiled and used for reclamation during operation and at the end of the life of the mine.

Mine Closure and Restoration

Mine closure and restoration costs are estimated at $27.1 million. Wherever practical, a progressive restoration approach will be followed.

At Joanna, the overburden disposal area will be reclaimed and used as capping material to re-vegetate waste rock and tailings disposal sites. The concentrate tailings pond will be restored using a multi-layer approach, which will isolate the contaminants from the environment.

Capital and Sustaining Capital Costs Estimates

The Feasibility Study is based on capital pricing as of the first quarter 2012. The level of accuracy of the capital cost estimates is within ± 15% for feasibility studies.

The pre-production capital costs are estimated at $422 million and include $87 million for contingencies and indirect costs. Indirect costs (owner's costs, Engineering, Procurement and Construction Management ("EPCM") and detailed engineering) of 20% have been applied on the process plant and the other surface infrastructures. Contingencies of 10% have been applied on the mill and infrastructures, and 20% have been applied on the waste rock and tailings impoundments. Sustaining capital expenditures over the life of the mine are estimated at $97 million, including $27 million for the closure and restoration of the site.
