CADILLAC drill hole at the Bibra deposit

Chalice Gold Mines Ltd is reviewing the potential to expand
its East Cadillac project in Quebec, Canada, following the
latest batch of assays.

Drilling to date has confirmed gold mineralisation along
about 3.5km of strike of the Larder Lake-Cadillac fault near
the Simon West prospect where Chalice has been focused.

An intercept of 11.6m @ 3.32 g/t from 235.9m down-hole
(including 1.6m @ 18.52 g/t for 244m) was reported from
Simon West, while another encouraging hit of 6.5m @ 1.77
g/t from 157m down-hole was made at the nearby North
Contact prospect.

Chalice plans to drill an additional hole to test the steep
westerly plunge of the high-grade mineralisation following
the last reported intercept at Simon West.

Only 40% of the planned 29,000m of drilling programme
had been completed at the time of print. Chalice had initially
proposed to drill just 8,000m before being enticed to extend
the campaign.
