Orestone Intersects Strong Gold Mineralization in Captain Drilling

Marketwired Canada
Orestone Mining Corp. (TSX VENTURE:ORS) (the "Company") is pleased to report
assay results for the recently completed 912 metre diamond drill program on the
Company's 100% owned Captain Project. Vertical hole C12-05 was drilled to a
depth of 550.2 metres and is the most significant of the seven holes completed
on the property. The hole intersected mineralized bedrock at 63 meters and
throughout the hole mineralization is associated with biotite-magnetite
alteration within monzonite porphyry dykes overprinted by potassic flooding.
Hole C12-05 returned two significant intervals of strong gold mineralization;
the upper zone grading 0.65 g/t gold and 0.06% copper (on an uncut basis) over
118.8 meters and the lower zone grading 0.41 g/t gold and 0.07% copper (on an
uncut basis) over 164.6 meters. The mineralization in hole C12-05 remains open
to depth.

The orientation of the mineralization is interpreted to be sub-vertical in
association with a 300 to 400 meter wide magnetic sheeted monzonite dyke system.
The magnetic anomalies are interpreted to trend north-south representing
important geological and mineralizing controls to outline this robust gold
target.
Hole C12-04 was located outside of the primary target area and returned no
significant values. Hole C12-03 located 500 meters east of C12-05 was drilled to
depth of 246.5 metres and is the most easterly hole on the property to date. Of
interest is that the bottom 70 meters of this hole intersected a potassic
altered monzonite dyke complex with similar associated alteration to that
encountered in hole C12-05 with gold grades of 0.13 g/t gold and 0.05% copper
which could indicate another mineralized porphyry system to the east.
"We are very pleased with intersecting long intervals of gold and copper
mineralization and in fact, although intervals of the hole are low grade, the
entire hole is mineralized from the bedrock contact at 63 meters to the bottom
of the hole at 550 meters. With higher grade sections of two to ten grams per
tonne gold, we have demonstrated the strongly gold enriched nature of this large
porphyry system and have learned a great deal about how to follow it.
Additionally hole C12-03 demonstrates that another mineralized porphyry system
may lay to the east," stated David Hottman, Orestone's CEO and President.
Prior to the next phase of drilling Orestone will complete a high resolution
magnetic survey of the property to further outline the alteration and associated
mineralization which are correlated to several interpreted sub-vertical magnetic
monzonite dykes zones that have a north-south trend.
The Captain project hosts a large gold-copper porphyry system measuring seven by
fourteen kilometers located 41 kilometers north of Fort St. James, British
Columbia and approximately 30 kilometers south of the Mt. Milligan copper-gold
deposit. The Mt. Milligan deposit has proven and probable reserves of 532 Mt
grading 0.20% copper and 0.38 g/t gold (Thompson Creek Metals website) and is
currently under construction by Thompson Creek Metals Company Inc. as a large
open pit mine and processing facility. The Captain Project features relatively
flat terrain, moderate tree cover and an extensive network of logging and Forest
Service roads suitable for exploration year around. The Company has all permits
in place to facilitate the next several phases of exploration; 30 line
kilometers of geophysics and 38 sites approved for drilling by the B.C. Ministry
of Energy and Mines.
The drill core was transported from the project to a secure warehouse facility
in Fort St. James where it was logged and cut by diamond saw into three metre
intervals. Half of the core is stored at the warehouse site and the other half
shipped by secure transport to Acme Labs sample preparation facility located in
Smithers, B.C., for analysis in Vancouver, B.C. Gary Nordin P. Geo.,
Vice-President of Exploration for Orestone Mining Corp., is a qualified person
under the NI 43-101 guidelines and has reviewed the technical content of this
