Opawica update on Atikwa Lake drilling and Bro property

ATIKWA LAKE AU-CU, ON, April 23 /PRNewswire-FirstCall/ - Opawica Explorations Inc. (TSX.V: OPW / OTC: OPWEF / FRANFURT: OE5A)("Opawica" / the "Company") announces drill hole results from the first hole of a six hole program at the Company's 100% owned Atikwa Lake property located near Kenora, Ontario.

A total of 4 holes have been drilled to date under the current program consisting of about 2200m of drilling. All holes are mineralized with intermittent pyrrhotite and chalcopyrite throughout most of each hole. The first four holes have been drilled on an initial strike extent of about 300m with holes AT-10-3 and AT-10-4 being the deepest holes ever drilled on the property at up to 655m in core length. Hole AT-10-4 (hole # 4) has demonstrated the widest mineralized section observed in core to date from drilling at Atikwa Lake. Hole AT-10-4 is a 650m hole in which the entire bottom 300m of this hole contains intermittent and varying amounts of finely disseminated sulphide mineralization consisting primarily of chalcopyrite and pyrrhotite within an andesite host rock. Assays for this hole are pending.

The current program is designed to test for gold and copper mineralization at depth, in a central portion of the property, below the Maybrun open pit zones and related NI 43-101 compliant resources for Atikwa Lake posted on the Company's website at www.opawica.com and on SEDAR.

After Atikwa Lake property reviews in 2007 and 2008, by two Canadian gold producers, and as a result of their consultation with Opawica Qualified Persons, the current program was designed to test for gold and copper mineralization to depth outside of the main basic lava flows ("BLF") that are host to the majority of the resources of the Maybrun open pit zone within 180m of surface. The first hole of the current program, AT-10-1, has confirmed gold and copper mineralization to a vertical depth of at least 250m (339m core length) in an andesite host rock outside of the BLF. The last 33m of this hole beyond the 1m of 9.38 g/t Au equivalent will now be re-evaluated given that the last two 1m sample lengths between 339m and 341m contained gold and copper mineralization.

    Note: Intervals are approximate true widths. AuEQ (Au Equivalent)
    calculated using US $800 per oz for Au and $2.00 per lb for Cu:
    AuEQ = Au+(Cu*22.05*2.00/800*31.1035).

In addition, a total of 22 samples from the historic tailings of the past producing Maybrun mine have been taken and will be assayed for Au, Cu, Ag and PGE group elements given the style of mineralization at the Maybrun zone as well as the proximity of gabbro units on the property and just off the property to the north. Further exploration targets for these elements exist on the Atikwa Lake property, outside of the Maybrun zones.

Assay results from the above program are expected throughout the next 30 days.

The above assaying of drill core from the Atikwa Lake property was completed by Swastika Laboratories of Kirkland Lake, Ontario.

Bro Massive Sulphide Cu-Ag-Pb-Zn Property, Yukon, Canada

--------------------------------------------------------

The Company is reviewing all available data to develop a drill program for its 100% owned massive sulphide prospect in the Yukon, near Ross River, to follow up on a 40 meter wide gossan zone, where past grab sampling (Lucky 7 group 1994) yielded up to 5.5 % copper, 34 % lead, 1.4 % zinc, 550 grams per ton silver, and 2.7 grams per ton gold.

Historical shallow drilling by Noranda (1978) on the Bro property returned gold values of up to 0.33 ounces gold (10.25 g/t Au) over 5.3 feet (1.6m).
