OSISKO MINING CORPORATION (TSX:OSK)(FRANKFURT:EWX)and OREX EXPLORATION INC.(TSX VENTURE:OX)(FRANKFURT:O5D) has provided shareholders with the results from the Reverse Circulation drilling program on the Goldboro Gold Property in Nova Scotia.
RC drilling is a method for obtaining chip samples of mineral occurrences at or near surface, in both overburden and bedrock. A total of 64 RC holes (holes OSK10RC-130 to OSK10RC-194), representing 505 metres, were drilled on the Goldboro Gold Property. The highlights of the RC drilling campaign are presented below:
"The RC drilling results have successfully identified bedrock gold mineralization on the East Goldbrook portion of the Goldboro Gold Property, where there has not been a lot of historic drilling, as well as at West Goldbrook" said Mark Billings, President and CEO of Orex Exploration. "We know that most of the gold-bearing structures at Goldboro come to surface. These RC drilling results particularly at East Goldbrook, which include 10.85 g/t Au and 25.65 g/t Au in two bedrock samples, provide us with some encouragement about the gold potential in these areas."
Although some of the RC drilling results could be used in a future resource estimate, this program was not intended to expand the NI 43-101 resource estimate; rather it was designed to explore new areas on the Goldboro Gold Property. RC drilling is a cost effective way of testing potential near-surface gold mineralized structures identified by the ongoing exploration on the Property. The program has been successful in the identification of future diamond drilling target areas.
The Reverse Circulation drilling was conducted by Archibald Drilling and Blasting of Truro, Nova Scotia. Sampling was done along roadside at approximately 20-metre spacing (no grid pattern). Overburden samples were collected over a 1-metre downhole length above the bedrock overburden interface. Bedrock chip samples were collected at 1-metre downhole length from the top of bedrock, generally to depths of 1-3 metres, but up to 12 metres in selected holes. All samples collected during the program were delivered by Mercator Geological Services or Armour Transport to the Minerals Engineering Centre (MEC) at Dalhousie University in Halifax, Nova Scotia, where analysis was carried out.
Each sample submitted to MEC was subjected to multiple stages of jaw crushing until grains were less than 4.0 mm. Analytical splits of 200 grams were obtained by riffle splitting and then pulverized with a ring and puck pulverizer to a grain size of less than 0.15 mm. A 30-gram split of this fraction was collected and analyzed by Fire Assay, lead collection and Atomic Adsorption Spectrometry (AAS) finish.
Option on Goldboro Gold Property Granted to Osisko Mining Corporation
In order to acquire a 50% undivided interest in the Goldboro Gold Property on or before September 29, 2013 (the Initial Option), Osisko Mining Corporation shall incur exploration and development expenditures in the amount of at least $1,500,000 on or before September 29, 2010; in the aggregate amount of at least $3,500,000 on or before September 29, 2011; and in the aggregate amount of at least $8,000,000 over the following two years, that is, on or before September 29, 2013. Osisko Mining Corporation may, at its sole discretion, accelerate and apply exploration and development expenditures to future years' expenditures and, accordingly, the Initial Option may be exercised sooner. Osisko Mining Corporation shall solely fund a prefeasibility study to earn an aggregate 60% interest (that is, an additional 10% interest) in the Property on or before September 29, 2015 (the Additional Option).
Osisko Mining Corporation and Orex Exploration are pleased to report that Osisko Mining Corporation has spent more than the $1,500,000 required in exploration and development expenditures in the first year of the Initial Option.
The technical information contained in this news release has been prepared by Peter Webster, P.Geo., President of Mercator Geological Services, and Bruce Mitchell, P.Geo, Technical Advisors to Orex and Qualified Persons under National Instrument 43-101 regulations.
