Opawica Explorations Inc. (TSX VENTURE: OPW) (the "Company" /
"Opawica") announces that further to partial assays released on
August 11, 2011 the Company has intersected further significant
gold and copper mineralization in the first two holes of the
current drill program at its 100% owned Atikwa Lake property
southeast of Kenora, Ontario. Complete assay results for all of
these first two holes are outlined in the table below along with
assays from the third hole (AT-11-03) of the current program which
was drilled about 900m north of the first two holes. Assays are
pending for the fourth hole of the program which is hole AT-11-04.

Note: AuEQ (Au Equivalent) calculated using US $800 per ounce for Au and US
$2.00 per pound for Cu and US $20 per ounce for Ag:
AuEQ = Au + (Cu x 22.05 x 2.00 / 800 x 31.1035) + (Ag x 20 / 800).
Further drilling is required to establish true widths of the
above intercepts for AT-11-01 and AT-11-02. The Maybrun Main Zone
in hole AT-11-02 is not a true width. This hole was drilled at a 55
degree declination through the Maybrun Main open pit zone, to test
an east-west projected Footwall Zone target, and drilled obliquely
to the projected strike of the Maybrun Main Zone. The open pit
Maybrun Main Zone, in this immediate area, is at least 90m in
vertical depth and at this location has a true width which
generally varies between 30m to 65m wide. Previous drilling by
Opawica in this immediate area has encountered anomalous
gold-copper intervals of less than 20m between, and separating, the
Maybrun Main Zone and the Footwall zone mineralization. It is not
yet known if these two zones can be considered as part of one
overall zonation for any future resource calculations or
considerations. Further drilling is required to determine the
extent and true dip, plunge and width for mineralization within the
Footwall Zone (Andesitic Unit) and its relationship to the Maybrun
Main Zones.
The first hole of the program (AT-11-01) was originally
interpreted to be drilled obliquely down dip into the Footwall
andesites to test for geology and mineralization at depth. The hole
intersected 657m of the altered Footwall andesites with some
sections containing significant gold and copper mineralization as
outlined in the above table. Hole AT-11-01 ended in mineralization
(up to 1m @ 7.30 g/t Au) within a dark porphyry matrix unit. This
hole will now be extended by further drilling.
From past and current drilling, the width of the Footwall
andesites that contain intermittent gold, copper, and now silver
mineralization is estimated to be at least 150m wide, at least 525m
down dip and at least 500m long (Andesitic Unit) and represents a
significant new discovery on the Atikwa Lake property. The above
Footwall mineralization and all Maybrun Main Zone holes drilled in
2010 and 2011 are separate from all previously reported mineral
resources outlined in the open pit Maybrun Zones and Footwall
Zone.
The trend and exploration approach at Atikwa Lake has
historically been oriented and directed on a 1400m long gold and
copper signature that generally strikes northwest to southeast,
predominately consisting of basalt lava flows (Maybrun Main
Zones).The new altered andesitic Footwall Zone discovery, and
drilling completed in hole AT-11-03 about 900m to the north (near
previously reported Inferred Resources in the North Zone) now
suggests several east-west orientations for at least 4 areas each
having about 800m of potential strike length.
The second hole of the program (AT-11-02) was drilled
(north-south) perpendicular to the projected east-west trending
strike of an IP anomaly within the Footwall Zone. The strike length
of this mineralization and anomaly is not yet known but could
extend in this area for at least 800m.
The Footwall Zone, and higher grade components therein, are wide
open to depth from about 120m deep vertically and onward. These
Archean-Proterozoic type units can extend for several thousand
meters in depth.
In addition, the recently discovered Footwall gold and copper
mineralization appears to be distal to some potential main
mineralizing event, fault or structure. In this regard, a 9m wide
fault-alteration zone almost entirely fracture filled with
carbonate has now been observed in hole AT-11-04. This hole was
drilled to a core length of 300m and was drilled from the same
location, and beneath, hole AT-11-02. All 300m of this core has
been sent out for assay.
Drilling will now focus in the areas of AT-11-01, 02 and 04,
with drilling on the North Zone and other east west trends to the
north to be carried out at a later date. A minimum 4000m of
drilling is funded and planned under the current field program.
