Good grades at Northern Dancer

posted on Sep 04, 2008 03:20PM


- All eight (8) holes reported good grades over wide widths of tungsten and molybdenum mineralization with significant higher-grade intersections

- 11,500 metre drill program focused on further expanding the limits of the higher-grade tungsten and molybdenum zones and upgrading a significant portion of the Inferred and Indicated resource

- Hole LT08-101 cut 50.00 metres grading 0.117% Mo and 0.13% WO3

- Hole LT08-100 cut 59.75 metres grading 0.054% Mo and 0.13% WO3

- Hole LT08-104 cut 74.00 metres grading 0.09% WO3, and 0.090% Mo and 94.10 metres grading 0.14% WO3 and 0.036% Mo, including 16.00 metres grading 0.21% WO3 and 0.097% Mo


TORONTO, ONTARIO--(Marketwire - Sept. 4, 2008) - Largo Resources Ltd. (TSX VENTURE:LGO) announced today that it has received results for the first eight (8) drill holes that are part of the recently completed 2008 drill program of 38 holes totalling 11,500 metres at the Company's Northern Dancer Tungsten-Molybdenum property in the Yukon. Largo's 2008 drill program focused on further expanding the limits of the higher-grade tungsten and molybdenum zones outlined during the 2007 drill program and upgrading a significant portion of the Inferred and Indicated resource, reported in the April 10, 2008 press release, to the Measured and Indicated category in order to support a Pre-feasibility Study. Preliminary pit modelling was used in order to help maximize the effectiveness of the drill program.

Numerous quartz veins and veinlets were intersected in the drill core containing varying amounts of scheelite and molybdenite, the principal tungsten and molybdenum minerals, respectively. The true width of the mineralization varies from 31 to 190 metres. Largo has received results for eight (8) holes totalling 1,212 samples. Results are pending on the remaining 30 holes. Core logging and splitting is continuing and expected to be completed by the end of the month.

Andy Campbell, Vice President, Exploration at Largo Resources, commented: "The results continue to be very encouraging with all eight holes reporting good grades over wide widths of mineralization. Higher grade molybdenum zones were intersected in six of the eight holes with values returned that were two to six times higher than the average deposit grade of 0.022% to 0.026% Mo. Drilling continues to confirm that the higher-grade tungsten and molybdenum zones are more extensive than previously thought. Our work indicates that a major northeast-southwest structure controls the distribution of mineralization, especially tungsten, and testing of this structural zone was a major focus of our drill program."

Northern Dancer, hosts widespread tungsten-molybdenum porphyry style mineralization, the core of which has been delineated by 94 diamond drill holes and 496 metres of underground workings. This work was done by AMAX Minerals Exploration from 1977 to 1980 (51 holes) and by Largo Resources which completed a 17-hole diamond drill program in 2006 and 26-hole program in 2007. On April 10, 2008 (see press release of the same date) Largo announced an updated NI 43-101 compliant resource comprising Indicated resources of 140.8 million tonnes grading 0.10% WO3 and 0.026% Mo and Inferred resources totalled 253.2 million tonnes grading 0.10% WO3 and 0.022 % Mo. This resource includes a higher grade tungsten zone containing an Indicated resource of 17.1 million tonnes grading 0.17% WO3 and 0.029 % Mo and Inferred resource of 18.7 million tonnes grading 0.16% WO3 and 0.023 % Mo. Please see the press release of Largo Resources dated April 10, 2008 for a description of the assumptions and parameters underlying these mineral resource estimates.

Please refer to Table 1 (Summary of Significant Assay Results - Northern Dancer Property, Yukon) which is appended to this news release for a summary of the above-noted drill results. Largo's website has the Northern Dancer 2008 Drilling Plan Map which provides a reference for the location of these holes on the property via the following link:

The Northern Dancer deposit is one of the world's largest known tungsten-molybdenum porphyry systems. The mineralization is hosted in fractures and veins associated with a northeast-trending sheeted vein system in calc-silicate (skarn) rocks and spatially related to a felsic intrusion (quartz-feldspar porphyry). The deposit, which has been tested by drilling for 1500 metres along strike, 500 metres vertically and 600 metres in width, remains open along strike to both the northeast and southwest as well as at depth.

Tungsten and molybdenum mineralization are concentrated in two zones which partially overlap. In the core of the deposit, there is a higher-grade molybdenum zone where molybdenite occurs within and adjacent to the felsic intrusion. Surrounding and partially overlapping the molybdenum zone is a much more extensive tungsten zone where scheelite occurs in northeast-trending sheeted quartz veins in skarn.

Analytical work is being carried out at Acme Analytical Laboratories Ltd. in Vancouver, British Columbia, an ISO 9001-2000 certified laboratory. The samples are crushed to 70% passing 10 mesh, split to 250 g and pulverized to 95% passing 150 mesh. A 5-gram split is analyzed for Mo and W using a phosphoric acid leach followed by ICP-emission spectrometry. Then a second 5-gram split is analyzed for 36 elements by ICP-mass spectrometry using a hot (95 degrees centigrade) aqua regia leach. Routine check assays are performed at SGS Minerals in Lakefield, Ontario on sample rejects. Largo employs a systematic QA/QC program including standards, duplicates and blanks. Andy Campbell, P. Geo., Largo's Vice President of Exploration, is the Qualified Person responsible for the scientific and technical work for the program as defined under National Instrument 43-101 and has reviewed this press release.
