Company Information
Opawica Explorations Inc. (TSX.V:
OPW / OTC: OPWEF / Frankfurt: OE5A) ("Opawica" / the "Company") 
announces that it has completed and filed on SEDAR a Preliminary 
Scoping Study (the "Study") regarding the Company's Atikwa Lake gold 
and copper project located near Kenora, Ontario.
The Study has been limited to a model of 1000 tpd projected to be 
mined from a 2,974,200 tonne surface and higher grade portion of the 
current NI 43-101 compliant 7,366,000 tonne Indicated resource of the
Maybrun open pit Main Zone of 0.64 g/t Au and 0.41% Cu. The head 
grade for the above 2,974,200 tonnes of open pit material is 0.911 
g/t Au and 0.574% Cu for a gold equivalent of 1.896 g/t Au. An open 
pit stripping ratio of 1.5 to 1 has been used to a depth of 40m that 
would commence from an existing open pit bench cut of the Maybrun 
Main Zone.
The preliminary economic analysis from the Study indicates positive 
preliminary economic considerations for an initial 1000 tpd operation
consisting of Capital Costs of $9,850,000, sustaining capital of 
$6,000,000, overall pre-tax cash flow of $26,592,000, all over a 
minimum of an eight year period. A preliminary Internal Rate of 
Return (IRR) of 30% is evident over the initial eight year period put
forth in the Study.
The Study has utilized a contract mining scenario that would include 
using existing tailings ponds, new surface infrastructure and some 
refurbished mill components used in past production (1973) on site. A
flow sheet consistent with past milling consisting of two ball mills,
floatation circuit and concentrator has been proposed. Overall 
recoveries of 92.6% has been used for gold and an 85% recovery in 
concentrate has been used for copper.
The Preliminary Scoping Study and economic analysis has been 
purposefully limited to 1000 tpd. The objective is to determine if 
the past footprint and related infrastructure of the former producing
Maybrun Mine can be used, at least in part, to re-instate production 
on the property on a shorter timeline and at significantly lower 
capital costs than may be otherwise possible under a larger scale 
mining operation that would include all resources presently outlined 
on the property. If positive cash flow can be attained from the 
initially proposed 1000 tpd operation, it may be possible to expend 
some cash flow on the entire Atikwa Lake property for further 
exploration and development.
The resources at the Atikwa Lake property as outlined in the August 
31, 2009 NI 43-101 report, filed on SEDAR, are as follows:

The above resources, as to tonnes, pounds and ounces are rounded to the nearest
1,000. The AuEq calculations in this release represent head grades and does not
include metallurgical recoveries or net smelter returns for gold and copper.
Mineral resources that are not mineral reserves do not have demonstrated
economic viability.
Based on the results of the Preliminary Scoping Study a Feasibility 
Study and further drilling has been recommended on the Atikwa Lake 
property.
Current drilling on the Atikwa Lake property is ongoing. A deep hole 
(AT-10-05) of about 650m has been completed into the Footwall Zone 
with assays pending. One further deep hole of 650m, on Section 844N, 
will be drilled into the Footwall Zone approximately 300m below the 
above open pit resources detailed in the August 31, 2009 NI 43-101 
report and about 200m down dip from hole AT-10-01 which returned the 
following assay results announced on April 23, 2010:

In addition, 6 shallow infill drill holes of up to 90m each have been
drilled within the open pit Maybrun Main Zone. Assay results are 
pending. A further 6 shallow holes of up to 90m each are scheduled to
be drilled in the open pit Maybrun Main Zone under the current drill 
program.
