VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/12/12 -- Aurizon Mines Ltd. (TSX:ARZ)(NYSE MKT:AZK) is pleased to announce results from the 2012 exploration program on the Heva and Hosco West Extension areas located 20 kilometres from Rouyn-Noranda, in north-western, Quebec.
"The drilling we have conducted at the Heva and Hosco West Extension areas this year has provided a high level of grade and thickness consistency and significantly improved our geological understanding of the property. We are pleased with the results obtained to date, and whilst we still have work to do in prioritizing the next drilling targets, our intended strategy to identify the extent of non-refractory gold mineralization on the property appears promising," said George Paspalas, Aurizon's President and CEO. "The objective in drilling at Heva is to identify sufficient non-refractory ounces to justify a staged development of the overall property with a lower risk and higher return initial project than the June 2012 Hosco Pit feasibility. We have now defined four distinct areas of mineralization within the area we were calling Heva, and have commenced work on a resource update incorporating this year's drilling results. We are also encouraged by the consistency of high grade refractory results obtained at the Hosco West Extension."
The objective of this drill program was to increase the inferred mineral resources in the Heva and Hosco West Extension areas near surface, and upgrade the depth potential where higher grades trends were present.
One hundred forty-three (143) holes totalling 53,234 metres have been completed in the 2012 drill program. Assay results for one hundred twenty one (121) holes have been obtained to date and twenty-two (22) holes are pending.
VDN trend
One of the new holes, JA-12-1112, has successfully identified a new discovery in the Heva West area called the VDN trend located north of the Cadillac Fault at the most western area of the Heva mineralized system. Mineralization starts near the bedrock contact, giving a broad mineralized interval of 1.7 grams of gold per tonne over a core length of 96.5 metres from 19.5 metres to 116 meters along the hole. The best results include the following intervals:
-- 3.8 grams of gold per tonne over 10.5 metres from 19.5 metres to 30.0
metres
-- 2.3 grams of gold per tonne over 25.0 metres from 71.0 metres to 96.0
metres
-- 3.7 grams of gold per tonne over 14.5 metres from 101.5 metres to 116.0
metres
Hole JA-12-1112 was collared 125 metres north of the Cadillac Fault following a north-west direction to cross cut perpendicularly a gold bearing vein set which is interpreted having a north-west orientation at surface. Free visible gold is commonly observed in the veins and fractures. The mineralization has been developed in a silicified and biotite rich fine grain sediment which is similar to what has been observed elsewhere in the Heva system, with no sulphide content observed.
Hole JA-12-1113, located 150 metres west of hole JA-12-1112, approximately on the same northing coordinate (see sketch attached), intersected a similar gold bearing structure. The best intersection returned grades of 7.6 grams of gold per tonne over 9.0 metres along the hole including 20.2 grams of gold per tonne over 3.1 metres along the hole.
An improved understanding of the exact orientation and geometry of this mineralized system is required, and different models are currently being evaluated. The mineralized intersection thickness should not be considered as "true width" at this stage, as additional drilling is required.
Heva and Heva East
The Heva area is located at the contact of the Cadillac Fault along a strike length of 950 metres. New results are concentrated inside the eastern side of the area, along a strike length of 400 metres, between sections 5400 and 5800.
Using a minimum cut-off parameter of 0.5 grams of gold per tonne over 5 metres between surface and a vertical depth of 200 metres, nine (9) holes returned between one and five mineralized intersections.
Using a cut-off grade of 3.0 grams of gold per tonne over a minimum true thickness of 3 metres, six (6) holes returned one to two positive intervals down to a maximum depth of 425 metres.
The following table includes the best results received to date from the Heva and Heva East areas (see sketch attached for location): A complete list of the drill results is also attached to this news release as Appendix A.

Mineralization is included inside a thick (10 to 60 metre-wide) strongly silicified and veined envelope with tourmaline, scheelite and a minor amount of pyrrhotite. Gold is found as free particles.
The new results from the eastern side of the deposit show for the first time, the expansion possibilities below 350 metres with results exceeding the minimum underground cut off parameters. At this depth, the mineralization footwall corresponds to a thick amphibolitized conglomerate unit.
Three hundred and fifty (350) metres eastward, following the Cadillac Break, two holes, spaced 100 metres apart, have intersected significant mineralization at a vertical depth of 225 meters, confirming the continuity of the Heva East Zone. The best result came from hole JA-12-1092, with an average of 6.9 grams of gold per tonne over 3.9 metres.
Hosco West
Of the five holes drilled to intersect the mineralization below 200 metres, three (3) holes returned intervals showing grades of between 4.0 and 8.5 grams of gold per tonne over a true width of between 3.0 and 11.0 metres. Mineralized intervals are located between 325 and 425 vertical meters and are still open in all directions.

At Hosco West, gold is located in several strongly altered lenses with an assemblage of quartz-albite-biotite, including finely disseminated arsenopyrite, pyrrhotite and accessory quartz veins. These locally stacked lenses are located inside a 25 to 80 metre-wide gold bearing structure immediately south of the Cadillac Fault.
"The new results obtained during the recently completed drill program have extended the limits of the Heva and Hosco deposits laterally and down dip, creating the potential to define a mining operation on this part of the property," said Martin Demers, General Manager of Exploration.
Outlook
The objective of the 2012 exploration program was to identify sufficient non-refractory gold mineralization that could lead to a staged development of the Hosco mineral reserves and improve the overall economics of the feasibility study competed in June 2012. Following the receipt of the remaining assay results from the 53,000 metre drill program completed in September 2012, a mineral resource estimate will commence using a dual approach to evaluate the potential of an underground or an open pit operation, and should be completed in the first half of 2013. Metallurgical test work will be initiated for different mineralized zones.
Quality Control and Qualified Persons
Core assays are performed on core sawed in half, with a standard ALS Chemex preparation and fire assay on 30-gram preparations followed by atomic absorption finish. All assays above 10 grams of gold per tonne are replicated on the same pulp preparation using a gravity finish. Certified reference material, duplicates and blanks are inserted in the sample sequence for quality control and controlled at the core's reception. Assay checking on pulp and coarse rejects are carried out on approximately 15% of samples. For additional information on Quality Assurance and Quality control, please refer to the current technical report on the property titled, "NI 43-101 Technical Report - Feasibility Study of the Hosco Deposit - Joanna Gold Project for Aurizon Mines Ltd. June 5, 2012", filed on Sedar at www.sedar.com. Primary assaying is performed by ALS Chemex and check assays were carried out by Laboratoire d'Analyse Bourlamaque of Val d'Or.
Drill hole planning, implementation and the quality control program is supervised by Martin Demers P.Geo., General Manager of Exploration, a qualified person as defined by National Instrument 43-101. Mr. Demers is also responsible for the scientific and technical information in this news release.
