Opawica (TSX VENTURE:OPW) Intersects Significant Gold and Copper Mineralization From Complete Results From Two Separate Holes in Maybrun Zone and New Footwall Zone, Rainy River Area, Ont.

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 16, 2011) - 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 * 22.05 * 2.00 / 800 * 31.1035) + (Ag * 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.
