North America Tungsten Continues to Intersect High Grades Throughout the "Amber Zone" Including 15 Ft. Averaging 4.27% WO3 (DDH-U2082)
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/01/13 -- North American Tungsten Corporation Ltd. (TSX VENTURE: NTC) ("NTC" or "the Company") is pleased to provide an update on its continuing underground diamond drill exploration program in the Amber Zone on its 100% owned Cantung tungsten mine in the Northwest Territories. Drifting toward this zone has commenced.
Stephen Leahy, CEO, stated: "We believe that this new Amber Zone will become an important integral component of our underground Life of Mine Plan at Cantung. We are very proud of the hard work and dedication of our Tungsten Team in the discovery and the definition drilling in the new Amber Zone."
Diamond Drilling was implemented to fill 450 ft. gap between high grade intercepts in drill holes U1943, U1936, and U1937, discussed in the NTC February 6th, 2012 news release, and holes U1978 to U1985, discussed in the NTC June 6th, 2012 news release. A total of 87 Diamond Drill Holes amounting to 25,000 ft. of drilling were completed. Many of the holes intersected one to three zones of mineralization. This recent phase of drilling verifies the continuity of the mineralization within the Amber Zone and the Central Flats over an area with an approximate strike length of 600 ft. and an approximate down dip length of 650 ft. In addition it opens up 800 ft. of strike length of potential mineralization to the east. Drilling is now commencing in the area of "Amber Zone East" to test the continuity of two areas. Drifting toward the Amber Zone West has commenced from 4 headings within the current mine workings.
Significant results from the drill program include 15 ft. averaging 4.27% WO3 (DDH - U2082), 22.7 ft. averaging 4.30% WO3 (DDH - US2083), 10.3 ft. averaging 3.60% WO3 (DDH - U2114) and 15.4 ft. averaging 2.44% WO3 (DDH - U2081). The table shown below provides the tungsten containing intervals and the estimated true widths for those intersections.
All drilling was completed from underground drill stations. All drill core was BQ and core recovery in the assay intervals was close to 100%. Sampling was based on lithology with a maximum individual sampled interval of 5 feet. The averaged assays shown in the table have a minimum bounding grade of 0.25% WO3.
Results from the 87 holes are summarized in the table below:
