Project Overview
The Croinor gold deposit located approximately 70 km from Val-d'Or, Quebec, consists of 38 high grade gold bearing quartz veins and remains open at depth. Recent production from the deposit totaled 8,081 ounces in three phases from two separate open pits from November 2003 to May 2005. The material was processed at a nearby Val-d'Or milling facility.
Gold mineralization is essentially associated with metasomatic pyrite located in quartz vein walls as well as in the strongly altered host-rock material of tectonic breccia. Gold occurs as inclusions within and along the edges of pyrite grains. Minor amounts of chalcopyrite and pyrrhotite are sometimes present with the pyrite. Occasionally, free gold is found within quartz veins of shear zones as well as in their strongly metasomatized walls.
Resource Estimation
After the open pit operations ceased in May 2005, two Mineral Resource estimates were completed for the Croinor gold project. The first was prepared in November 2005 by Carl Pelletier of InnovExplo Inc. and was entitled "NI 43-101 Technical Report for the Mineral Resource Estimate of the Croinor gold project". This formed the basis of the July 2009 Preliminary Economic Assessment by Francois Chabot of Golder Associates (the "PEA"). The second, prepared by Pierre O'Dowd in September 2009 entitled "NI 43-101 Resource Estimate Update and 2008 Technical Report on the Croinor 1 and 2 Projects", incorporated a 12,648-meter drill program conducted from 2007 to 2009. The latter forms the basis of the current Study.

Reserve Estimation
The PEA prepared by Golder Associates in July 2009 provided for a probable economic reserve of 309,000 tonnes based on the 2005 InnovExplo resource estimate. The Prefeasibility Study provides for 689,829 tonnes based on the 2009 O'Dowd resource estimate and a gold price related reduction in the cut-off grade.
This Study also provides a complete update on the information provided in the PEA and includes a detailed mine plan and project pricing and economic forecast updates. Mill throughput increased by 109% compared to the PEA. While the life of mine capital expenditures increased due to the increased mined tonnage, the increased production rate and other changes arising from the full review conducted during the Prefeasibility Study, the pre-tax cash flow rose to $47.4 million, an increase of 150% compared to the PEA.
The underground mine reserves were determined using an undiluted cut-off grade of 5.0 g/t and minimum mining width of 1.8 metres. The estimated proven and probable reserves totaled 185,260 oz after applying a mining recovery of 85% for room-and-pillar mining and 95% for long-hole mining, with a dilution factor of 5% for room-and-pillar stopes and 20% for long-hole stopes.

Improvements to the Golder Study
The primary reasons for the improvement over the Golder Study are:
- Resource increase in accordance with the O'Dowd report;
- Mine tonnage increase from 309,805 tonnes (82,877 ounces Au) to 689,829
tonnes (185,260 ounces Au);
- Mill throughput increase from 400 tpd to 500 tpd;
- Improved gold prices;
- Recovered gold production increased from 80,806 ounces to 170,556
ounces;
- Detailed mine plan completed to facilitate determination of proven and
probable reserves;
- Major contractors (including potential custom milling partners) and
suppliers contacted for updated project pricing;
- Implementation of cost reduction measure such as extension of the power
line to service the site eliminating the use of high cost generators.
Mining
The underground mine design provides for a mine plan containing 689,829 tonnes of ore assaying 8.35 g/tonne. Total mine ore production over the current five-year mine plan is expected to be 180,629 oz.
A summary of the annual mine plan is as follows:
-------------------------------------------------------------------------
Year Gold
Ore Mined Ore Milled Production
(tonnes) (tonnes) (oz)
-------------------------------------------------------------------------
Pre-production
-------------------------------------------------------------------------

-------------------------------------------------------------------------
4 127,733 130,329 39,181
-------------------------------------------------------------------------
The mining method will be 80/20 ratio of room-and-pillar mining and long hole mining. For stopes less than 45 degrees the mining method will be room and pillar with long hole for the remaining stopes. Contractors will be utilized for all mine development, mine production and ore haulage activities. A small staff workforce will be hired to provide technical support and direction to the contractors.
Processing and Metallurgy
Ore from Croinor will be processed at a mill in the Val-d'Or area which will have excess capacity for the duration of the Croinor operation. Contact has been made with potential custom milling partners and tentative commitments have been arranged for processing the ore. Ore previously mined from the Croinor open pit operations was processed at a mill in the area and based on actual results achieved during these runs, a gold recovery of 97.5% has been used in this Study. 42,000 tonnes of ore which will be processed during the pre-production period is deemed to be capital production and is not included in production nor is the revenue derived there from. Life of mine gold production is 170,556 ounces.
Infrastructure
A 25 KV transmission line will be extended from the nearby Chimo mine site to the Croinor site to supply electrical power for the site.
The existing roads to and on the site will be upgraded to support vehicle travel to and from the site including the offsite transportation of ore for processing.
The mine will be dewatered and the existing 300-meter ramp and 2 km mine level development will be reconditioned and extended to meet mine requirements. The existing 200-meter deep shaft will be reconditioned and used as a ventilation raise and emergency escape way. Ore and waste haulage to surface will be via ramp.
One existing building will be set up for use as a garage and additional buildings will be constructed to serve as dry, offices and core shack.
Operating Costs
Operating costs over the life of mine are projected to average US$572 per oz. The cost distribution is as follows:

OUTLOOK
Subject to successful project financing, mine dewatering is expected to commence during the fourth quarter of 2010. Commercial production is anticipated 14 months following commencement of dewatering. During the pre-production period, 42,000 tonnes of ore will be processed and 10,073 oz of gold will be produced commencing in the 10th month following the announcement of the decision to commence mine dewatering.
The project exhibits significant opportunities to improve on the project economics:
- Completion of infill and down plunge exploration drilling aimed at
expanding the current resources and reserves. A 6,050-meter program is
ongoing and will be completed during the fourth quarter of 2010;
- Reinterpretation of the vein structure with further drilling could
increase the ratio of lower cost long-hole stoping to room-and-pillar
mining;
- Mining of a small open-pitable resource located west of the existing
west pit and recovery of remnant ore in the existing west pit;
- Incorporation of technology such as gravity separation to reduce mill
operating cost.
- Evaluation of the potential to apply ore sorting technology at the
Croinor site.
Blue Note, as operator of the joint venture, is proceeding with other engineering studies and reports required for the development of the project. Blue Note expects to have everything in place to begin mine dewatering by the fourth quarter of 2010, subject to the receipt of the government approval to operate which is now expected to be received by the end of August.
