Aurizon Outlines Exploration Plans for 2005

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 28, 2005) - Aurizon
Mines Ltd. (TSX:ARZ)(AMEX:AZK) is pleased to report the 2005 exploration
plans for its' Casa Berardi project, where a positive feasibility study
has recently been completed. A $7 million budget has been planned for
surface and underground programs to explore for new mineral resources,
and to upgrade the quality of known gold resources from underground so
that they can be included in the Casa Berardi mineral reserves and
underground mine plan.

Upgrade of Current Mineral Resources

Underground exploration will be conducted from the 550 metre level track
drift which will be extended east for a distance of approximately 1
kilometre. Deep drilling of the high grade extension of Zone 113 is
currently being conducted from a crosscut on the 550 metre level to
depths between 900 and 1,100 metres. The extended 550 metre track drift
will be used to explore and infill drill Zones 118 to 120. A total of
47,000 metres of drilling is planned from underground in 2005.

New Mineral Resources

The 2005 surface drill program will consist of 17,000 metres of
drilling, following up last year's exploration successes at Zone 140 and
Zone 157 in the vicinity of the East Mine. Some of the drilling of Zone
140 will take place from the 280 metre level drift.

A geophysics and geochemistry program is planned west of the West Mine.
This new information should create new target zones for drilling. An
additional 2,000 metres of drilling is planned for this area.
