Aurizon Reports Further Results From Its Joanna Property Including 3.1 Grams of Gold Over 51.2 Metres and 4.7 Grams of Gold Over 29.5 Metres

Market Wire, April, 2008

Aurizon Mines Ltd. (TSX: ARZ)(AMEX: AZK) is pleased to announce additional drill results from the East Block of its Joanna project, located 20 kilometres from Rouyn-Noranda, in north-western, Quebec.

To date, one hundred and eighty six (186) holes totalling 70,980 meters have been completed by Aurizon at Joanna with the objective of confirming results from previous drilling and to extend the lateral extension of the mineralized zones. Results from one hundred and thirty four (134) holes have been received to date, with results from the most recent twenty four (24) holes reported herein.

Infill drilling

Two holes, JA-139 and JA-93, returned respectively, 4.7 grams of gold per tonne over 29.5 metres including 60.5 grams of gold per tonne over 1.2 metres, and 3.1 grams of gold per tonne over 51.2 metres including 63.8 grams of gold per tonne over 1.4 metres.

Effective as of September, 2007, mineral resources at Joanna are estimated at 11.3 million tonnes averaging 1.7 grams of gold per tonne, or 630,000 ounces in the indicated mineral resource category and 28.6 million tonnes averaging 1.6 grams of gold per tonne, for 1.42 million ounces in the inferred mineral resource category. Details of key assumptions, parameters and methods used to estimate the mineral resources and other information required by National Instrument 43-101 is included in the Technical Report - Resource modeling & estimation update - Joanna Gold deposit, dated October 26, 2007, filed under the Company's profile on www.sedar.com .

Work in Progress

- A preliminary technical assessment report which will focus only on the mineral resources referred to above, which are located in the upper part of the East block, above the 200 metre level, is in the final stages of completion.

- Four rigs are currently active on the property, conducting infill drilling within the East block existing mineral resource contour and along its lateral extension. Drilling is being performed on 100 metre spacing, 1,600 metres west of the known indicated mineral resources and 450 metres to the east. Assays are pending on fifty two (52) holes. The results of this infill drilling program will be integrated into an updated mineral resource estimate later this year.

- Five holes have been completed recently along the dip extension of the East block to test high grade enrichment below the 500 metre level. Assays are pending.
