McEwen currently owns 6.25 million Timberline shares, or around 3.3% of the company, along with 6.25 million warrants.

Excluding existing ownership, McEwen, which has operations in Nevada, Canada, Mexico and Argentina, expects to issue around 1.84 million shares on closing for a transaction value of $18.8 million.

Timberline shareholders will receive 0.01 of a share of McEwen's common stock for each Timberline share held, representing a value of $0.102 per Timberline share, or a premium of 132%, the companies said.

Timberline Resources, a Nevada based exploration company focused on gold and copper discoveries, would be required to pay McEwen a termination fee of $400,000 if it terminates the agreement.
