D. Bruce McLeod, President and CEO of Tenajon stated “We are pleased to complete this transaction which has successfully consolidated the ownership of two highly prospective gold assets within the Stewart camp, and will allow Tenajon shareholders to directly benefit from further success in exploring and developing the Silver Coin and Summit Lake properties.”

“We are very happy to complete the acquisition and excited about advancing the further potential of both projects. As announced by Pinnacle on May 15th, a $2.5 Million exploration program is currently underway on Silver Coin including Kansas which is aimed at expanding the known resource” said Paul Saxton, President and CEO of Pinnacle Mines Ltd.

Pinnacle has issued 13,500,000 fully paid shares of Pinnacle (“Pinnacle Shares”) and shall reimburse Tenajon up to $200,000 in cash in respect of reclamation deposits, exploration costs incurred by Tenajon on the Summit Lake property and certain other expenses.
