AIM: MARL

TORONTO, Nov. 30 /CNW/ - Mariana Resources Limited ("Mariana" or the "Company") (AIM:MARL), an exploration and development company focused in Argentina and Chile, is planning to undertake a global private placement (the "Global Private Placement") to raise gross proceeds of £6.2 million (approximately C$9.9 million) at a price of 40 pence per ordinary share. The Global Private Placement will be comprised of the following components:

							1.	placement to investors in North America ("North American Placement"), pursuant to the Exemptions (as hereinafter defined), led by Paradigm Capital Inc. and including GMP Securities L.P.; and
							2.	placement to investors outside of North America brokered by finnCap Limited and including the Company's nominated adviser, RFC Corporate Finance Limited.

The securities issued under the North American Placement will be offered by way of Private Placement exemptions (the "Exemptions") in all the provinces of Canada and in the United States on a private placement basis pursuant to exemptions from the registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act").

Both components of the Global Private Placement are to be closed simultaneously with identical commercial terms and conditional on each other.

The net proceeds from the Global Private Placement will be used to accelerate the exploration of the Company's project portfolio in Argentina and Chile, and for general corporate and working capital purposes.  The Company's primary focus will be to fast-track exploration drilling at its flagship Las Calandrias gold discovery, located in the prospective Deseado Massif gold district in southern Argentina, to define a resource and evaluate the economic potential of the project.

Each component of the Global Placement is scheduled to close on or about December 9, 2010 and will be subject to certain conditions and regulatory approvals.
