MARIMACA ANNOUNCES CLOSING OF C$20 MILLION STRATEGIC INVESTMENT BY MITSUBISHI CORP.

Marimaca Copper Corp. has closed the previously announced $20-million equity investment by Mitsubishi Corp. by way of non-brokered private placement. Proceeds from the strategic investment will be used to advance and accelerate the development of the company's flagship Marimaca copper project located in the Antofagasta region, Chile.

Pursuant to the strategic investment, Mitsubishi acquired an aggregate of 4,640,371 units consisting of one common share and one common share purchase warrant at a price of $4.31 per unit. Each warrant will entitle Mitsubishi to purchase one additional common share at an exercise price of $5.60 for a period of 24 months following closing. As a result of the strategic investment, Mitsubishi now owns approximately 5.0 per cent of Marimaca's issued and outstanding common shares on a non-diluted basis.
