Grande Portage and Quaterra File Herbert Gold Project NI 43-101 Compliant Technical Report on SEDAR
VANCOUVER, BC, April 12, 2013 -- Grande Portage Resources Ltd. (TSX-V GPG) ("Grande Portage" or "the Company") and its joint venture partner Quaterra Resources Inc. (TSX-V: QTA, NYSE Amex: QMM) are pleased to announce that they have filed with SEDAR a Canadian National Instrument 43-101 compliant technical report on the Herbert Gold Project located near Juneau, Alaska.
The Report was prepared by D.G. DuPre & Associates of Delta, British Columbia. It follows the updated independent resource estimate for the Herbert Gold project announced in a news release on February 28, 2013, also prepared by D.G. DuPre & Associates. The technical report also includes a description of the project history, geology, mineralization, drilling, sampling procedures and laboratory Quality Assurance/Quality Control procedures, as well as recommendations. There are no material differences between the mineral resource estimates in the technical report and the February news release.
The qualified persons for the DuPre technical report are David DuPre and Dr. David Webb. Mr. DuPre and Dr. Webb are independent of Grande Portage Resources Ltd. and Quaterra Resources Inc. and are Qualified Persons as defined by NI 43-101, and are responsible for the technical content of this press release.
The complete NI43-101-compliant technical report is available at www.sedar.com and on the companies' respective websites.
Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied. The mineral resource estimates referenced in this press release use the terms "Indicated Mineral Resources" and "Inferred Mineral Resources". While these terms are defined in and required by Canadian regulations (under NI 43-101), these terms are not recognized by the U.S. Securities and Exchange Commission ("SEC"). "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade without reference to unit measures. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. Grande Portage Resources Ltd. is not an SEC registered company.
