VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 19, 2013) - Quaterra Resources Inc.

"We are pleased to monetize a portion of our central Mexico mineral assets and bring in additional non-dilutive funding to the Company. This action is consistent with our recently announced strategy of monetizing, simplifying and focusing our portfolio of mineral assets. Funds received from the Goldcorp transaction will be used to retain and advance the five properties remaining in the IFA in a highly prospective mineral district in Mexico. We are pleased to continue our exploration in Mexico with Goldcorp which recognizes the exploration potential of the region and the value of Quaterra's team," says Quaterra President and CEO Steven Dischler.
