Amended NI43-101 filed for Nieves preliminary economic assessment

Quaterra and its 50% joint-venture partner Blackberry Ventures I, LLC, have filed on SEDAR an amended Canadian National Instrument 43-101-compliant technical report for the preliminary economic assessment (PEA) of their Nieves silver property in Zacatecas State, Mexico.

The amended report was prepared by M3 Engineering & Technology of Tucson, Arizona, and follows the announcement of the Nieves PEA in a news release on September 19, 2012. The technical report includes a description of the project resources, mine plan, capital costs, operating costs, metallurgy and financial analysis. There are no material differences between the technical report filed on November 2, 2012 and the amended report filed today. The change relates to a decimal point error in figure 22-4 for lead and zinc values. Because lead and zinc were not used in the model, there is no effect on project economics. In addition, the estimated concentrate grade was clarified at the end of section 13.4.

The Qualified Person for the updated Nieves project resource estimate in this release is Jason Baker, P. Eng., of Caracle Creek International Consulting Inc. (CCIC) of Toronto, Canada. Zsuzsanna Magyarosi Ph.D., P.Geo. (APGO#2031), also of CCIC, is the Qualified Person responsible for the QA/QC evaluation. Doris M. Fox M.Sc., P.Geo., also of CCIC, is the Qualified Person responsible for the site visit and sampling procedures. The Qualified Person for the preliminary economic assessment is Joshua Snider P.E. with M3 Engineering & Technology Corp., Tucson, Arizona. The Qualified Person for the mining portion of the PEA is Jeffery Choquette P.E. of Butte, Montana, and for metallurgy Thomas L. Drielick P.E. of M3 Engineering & Technology Corp., Tucson, Arizona. The complete NI43-101-compliant technical report is available at www.sedar.com and on the company's website.

Disclosure note

The mining terms "indicated resource" and "inferred resource" are used in this news release in accordance with Canadian regulations but are not recognized by the United States Securities and Exchange Commission. For clarification, the Company has no properties that contain "reserves" as defined by the SEC and is providing the forgoing, in part, in order to meet its requirements under National Instrument 43-101 adopted by the BC Securities Commission and the Canadian Securities Administrators.

A PEA should not be considered to be a pre-feasibility or feasibility study, as the economics and technical viability of the Project have not been demonstrated at this time. A PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too geologically speculative at this time to have the economic considerations applied to them to be categorized as Mineral Reserves. Thus, there is no certainty that the production profile concluded in the PEA will be realized. Actual results may vary, perhaps materially.

Some statements contained in this press release are forward-looking statements within the safe harbor of the Private Securities Litigation Reform Act of 1995. These statements generally are identified by words such as the Company "believes", "expects", and similar language, or convey estimates and statements that describe the Company's future plans, objectives or goals. Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Further information regarding risks and uncertainties which may cause results to differ materially from those projected in forward-looking statements, are included in filings by the Company with securities regulatory authorities. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date thereof. The Company does not undertake to update any forward-looking statement that may be made from time to time except in accordance with applicable securities laws. References may be made in this press release to historic mineral resource estimates. None of these are NI 43-101 compliant and a qualified person has not done sufficient work to classify these historic estimates as a current mineral resource. They should not be relied upon and Quaterra does not treat them as current mineral resources.
