Sainte-Marguerite gold ore resources evaluation commences

RIMOUSKI, Aug. 3 /CNW Telbec/ - Puma Exploration has recently completed
its first 2005, program on the Sainte-Marguerite property and will now
commence a gold resource evaluation that could lead to an open pit mining
operation on the "Fraser 3" zone that is contained within the much larger
Fraser zone.
The gold mineralization in the "Fraser 3" zone is defined by 12 recently
drilled vertical holes between 18 and 40 metres deep for a total of
350 metres. The continuity of the Fraser 3 mineralization has been evaluated
over a strike distance of 160 metres, with a drill spacing of 20 metres,
including earlier drilling.
The recent drill programs has confirmed the presence and continuity of
two mineralized zones containing sub-horizontal, gold-bearing quarts veins
over strike distances of 35 and 70 metres, respectively. The best samples
obtained from the mineralized zones, which remain open at both ends, carry
gold values from 1.6 gms/t to 40.8 gms/t Au.

This evaluation program will allow Puma Exploration to estimate the
economic value of the "Fraser 3" zone and to plan further definition drilling
in advance of a mining decision. The evaluation program will incorporate all
data, including data from the 50 drill holes drilled prior to 2005 which have
defined the 650 metre-long Fraser zone that remains open toward east.
