North American Tungsten Investigates Tailings Reprocessing Potential at the Cantung Mine Site

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/03/13 -- North American Tungsten Corporation Ltd. (TSX VENTURE:NTC) ("NTC" or "the Company") is pleased to announce that metallurgical testing and analysis of material from Tailing Pond 3 is ready to commence. The next phase of the tailings reprocessing plan is ready to begin now that the 2011 and 2012 drilling and modeling program has been completed.

History

Tailings Pond 3 was the primary storage facility for all underground and surface production from 1971 until February 2007. During this period of operation, mill feed graded considerably higher than current feed, leading to significant amounts of WO3 being discarded as tailings, despite good plant recoveries at the time. The tailings pond has a maximum height of 41 meters, a footprint area of approximately 102,000 square meters and a volume of approximately 2.24 million cubic meters, providing a substantial readily available prospective source of material for reprocessing and resource recovery.

Drilling and Conceptual Modeling Program Complete

A sonic drill program throughout the summer of 2011 and spring of 2012 was conducted to explore the possibility of reprocessing unrecovered WO3, Cu and Au from Tailings Pond 3. The program was designed to establish the approximate tonnage and grade of the available tailings which were then compared to historical production statistics. A total of 25 holes were drilled with a spacing of approximately 200 feet depending on ground conditions. Tailings samples were acquired at 5 foot intervals over the entire length of each hole and assayed at ACME Laboratories, Vancouver. In-house assay work along with preliminary metallurgical work was also conducted on site. A preliminary block model was constructed using Minesight software (Figure 1).

Tons and grade stated

The potential tonnage and grade determined by the drilling and modeling program are comparable with available historical mill production statistics from 1974 to 2006.

With new multiple element assays from the sonic drill program, the potential opportunity for also recovering associated secondary Cu and Au as well as the primary WO3 from the tailings can also be determined and incorporated into the design of a possible reprocessing flowsheet.

The potential quantity and grades are conceptual in nature. There has been insufficient exploration and metallurgical testing to define a mineral resource and it is uncertain if further exploration and metallurgical testing will result in the delineation of a mineral resource.

Upcoming Testing Phase

The next phase in the tailings reprocessing plan will include baseline flotation test work plus locked cycle flotation tests to determine the feasibility of recovering a marketable concentrate. Magnetic separation, presently used in the production plant flowsheet, will also be evaluated. The program is expected to conclude with off-site testing of a bulk sample, providing necessary scale up information for commercial processing.

Mr. Stephen Leahy, CEO of the Company stated "A positive feasibility for the tailings reprocessing project will certainly make it a priority for the Cantung Mine as it has the potential to add significantly to not only our production but to our overall mine life resource."

Quality Assurance Sample analyses were done by ACME Labs in Vancouver. Check assays were completed at Becquerel Laboratories, Mississauga, Ontario, and the in-house assay lab at the Cantung Mine site utilizing both XRF and colorimetric methods. Results for the three labs were acceptable.

Qualified Person The technical information contained in this release has been reviewed and approved by Finley Bakker, P. Geo, Superintendent of Technical Services for the Cantung Mine for the Company, who is a qualified person pursuant to the terms of National Instrument 43-101 of the Canadian Securities Administrators.
