North American Tungsten Continues to Intersect High Grade Mineralization at Cantung Mine
Highlights: Continued expansion of the new mineralized zone to the east and west. - The mineralized zone has expanded above the 3700 Level to the west. - Exploration drift on 3700 Level is approximately 100 ft east of western most intersection. - New mineralization is west of any underground workings and is open in three directions. - Hole U-1655 intersects 62.3 feet at 2.45% WO3, including 33.4 feet at 4.02% WO3.
North American Tungsten Corporation Ltd. (TSX VENTURE: NTC.V) ("the Company") is pleased to announce that the Q1-09 Cantung Mine exploration and delineation drill program continues to intersect high grade tungsten mineralization.
The drill program continues to successfully identify high grade tungsten mineralization down to the 3400 Level, approximately 300ft below the current lowest mine level workings (3700 Level). It has also delineated mineralization above and to the west of the current workings. Development of the decline to the 3660 Level to access the high grade mineralization is well advanced and is scheduled to intersect mineralization this month.
"Ongoing definition and exploration drilling at Cantung has discovered a high grade western extension at the lower levels of the West Extension zone of the mine. This extended zone is within 100 feet of existing underground development and further highlights Cantung potential for defining additional mineralization" said North American Tungsten Chairman and CEO, Stephen Leahy. "This recent exploration drilling by Cantung geology and engineering teams is adding significant near term value as we continue to focus on expansion of the existing resource and extension of the Cantung mine life."

Section 190,765 (above) was drilled at an orientation 30 degrees west of engineering section (210 degrees) to intersect mineralization perpendicular to strike. The section is 100 ft east of the geological cross section reported in the August 14, 2008 press release. Grades are comparable but the average thickness has increased as indicated in the above table.

Section 190,800 was drilled at an orientation 30 degrees west of engineering section (210 degrees) to intersect mineralization perpendicular to strike. This section is approximately 25 feet west of the geological cross section reported in the August 14, 2008 press release. Due to location of the drill cut out of the previously reported section, drilling was often sub parallel to the dip and as such it was difficult to estimate true thickness and grade. The new section was drilled from a better positioned drill station that gave a much better indication of grade and thickness. Previous estimates were in the order of 8 ft average true thickness. The average thickness is now estimated to be closer to 25 ft. This is significant as this is the eastern most portion of this lens and shows an overall increase in thickness, as above.

Section 190,115 was drilled at an orientation 30 degrees west of engineering section (210 degrees) to intersect mineralization perpendicular to strike. Hole U1655 was drilled horizontally and intersected mineralization above the 3700 elevation. This is significant in that the mineralization is beginning to show continuity above the level. An exploration drift is less than 100 ft east of this intersection and has already intersected mineralization, (see above table).

The above figure illustrates that the mineralized intersection (red zone) is significant as there have been no sections drilled from underground to the west. The mineralized intersection is above and north of the zone currently being drilled (in blue). The area in green is the current mine workings and shows the limit of what was previously thought to be the extent of the mineralization.
Quality Assurance The Company instituted a QA/QC program consistent with best industry practice standards. Elements of the program include chain of custody, as well as standard and blank samples. Samples are assayed at the mine assay laboratory and selected samples are sent to ALS Chemex and to Global Discovery Labs (Teck Cominco Limited) both in Vancouver for duplicate assaying. Results from the QA/QC program have to date been satisfactory.
