Harte's Plan

Harte is in the process of permitting the site in order to commence an "Advanced Exploration and Bulk Sampling program" in April, 2013. Details of this program are currently being finalized and will be submitted to the Ministry of Northern Development & Mines for approval. In addition, management of Harte is sourcing equipment, including electricity delivery options, which would dramatically lower the capital requirements and translate into improved IRR's.

"This PEA is an excellent endorsement of the viability of the Sugar Zone Deposit becoming a new Ontario, high grade, gold mine" said Stephen G. Roman, Harte's, President & CEO. "The operating and consumable costs used in the PEA are current and taken from existing mines in the area. With mine and mill optimization, as well as sourcing re-furbished components, we expect to significantly improve the already great economics of this project" said Mr. Roman.

The PEA will be posted on www.SEDAR.com within 45 days as well as on the Company's website www.hartegold.com.

QA / QC Statement

The PEA was prepared in conformance with National Instrument 43-101 by NordPro Mine & Project Management Services Ltd. (NordPro) of Thunder Bay, Ontario. The report was prepared by Brian LeBlanc, P. Eng. of Nordpro and NordPro Associate Malcolm Buck, P. Eng., each a "Qualified Person" under the Instrument and they have supervised the preparation of the information that forms the basis of the written disclosure in this news release.

NordPro utilized the Watts, Griffis and McOuat resource estimate as reported in the "Technical Report and Mineral Resource Estimate and Mineral Resource Estimate Update for the Dayohessarah lake property, Ontario for Harte Gold Corp." dated February 17, 2012. The PEA uses Inferred Resources which are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that the results predicted by this PEA will be realized. The mineral resources estimate could be materially affected by environmental, geotechnical, permitting, legal, title, taxation, socio-political, marketing or other relevant issues.
