Largo Undertakes New Drill Program at Northern Dancer Tungsten-Molybdenum Project, Yukon

- Further testing of the higher-grade tungsten and molybdenum zones outlined during the 2006, 2007 & 2008 drill programs

- Initial drilling of Marilyn Creek - an untested exploration target immediately north of Northern Dancer Deposit

- Company makes good progress on Preliminary Economic Assessment (PEA)

TORONTO, ONTARIO--(Marketwire - Sept. 27, 2010) - Largo Resources Ltd. (TSX VENTURE:LGO) announces that two drill rigs have begun a 9-hole, 2,500-metre diamond drill program on the Company's 1,500 hectare Northern Dancer Tungsten-Molybdenum property which straddles the Yukon-British Columbia border 290 kilometres east of Whitehorse.

The 9-hole diamond drill program will further test the higher-grade tungsten and molybdenum zones intersected in the 2006, 2007 and 2008 programs. This will be done through a series of angled drill holes across the deposit to test the higher-grade zones. This higher grade zone is estimated to contain a Measured and Indicated resource of 60.3 million tonnes grading 0.137% WO3 and 0.045% Mo (WO3 equiv 0.215%) and Inferred mineral resource of 5.4 million tonnes grading 0.134% WO3 and 0.047% Mo (WO3 equiv 0.214%) at a 0.17% WO3 equivalent cut-off grade (for details of resource estimate see Press Releases dated May 31, 2010 and March 12, 2009).

Also, exploration drilling of the Marilyn Creek showing, an untested exploration target, is currently underway. Marilyn Creek lies 500 to 1,000 metres north-northwest of the Northern Dancer deposit. It was discovered during a mapping and sampling program in summer of 2007. This program is expected to take four to six weeks to complete with results from the first holes anticipated to be received in about four weeks.

The Preliminary Economic Assessment (PEA) for the Northern Dancer Project currently underway (see Press Release dated May 31, 2010) is making good progress. Completion of the PEA is anticipated by the end of the year. It is currently assessing various mining methods to establish the most cost effective method to exploit the previously identified higher grade zone, although no firm conclusions have yet been drawn.

As part of further metallurgical testwork program, Largo has also successfully completed an investigation into ore sorting techniques using Dual Energy X-Ray Transmission (DEXRT) techniques to improve the economics of the project. Currently, Largo is targeting a rejection of 35% of the crusher feed, whilst recovering 95% of the tungsten and 90% of the molybdenum feed contents. The proposed flowsheet is projected to produce a molybdenum sulphide flotation concentrate, and gravity and flotation tungsten concentrates that will be readily marketable.

Northern Dancer hosts widespread tungsten-molybdenum porphyry style mineralization, the core of which has been partially delineated by 134 diamond drill holes and 496 metres of underground workings. This work was done by AMAX Minerals Exploration from 1977 to 1980 including 51 holes and by Largo, which completed 17 holes in 2006, 26 holes in 2007 and 38 holes in 2008. In March 2009, Largo announced an updated NI 43-101 compliant resource (see press release March 12, 2009).

This resource consists of: Measured resources of 30.8 million tonnes grading 0.114% WO3 and 0.030% Mo, and Indicated resources of 192.6 million tonnes grading 0.100% WO3 and 0.029% Mo. The Measured and Indicated mineral resource estimate contains 500.1 million pounds of WO3 (226.9 k tonnes) and 143.8 million pounds of Mo (65.2 k tonnes). Inferred resources were estimated to be 201.2 million tonnes grading 0.089% WO3 and 0.024% Mo containing 393.1 million pounds of WO3 (178.3 k tonnes) and 107.7 million pounds of Mo (48.9 k tonnes) (for details of resource estimate see Press Releases dated May 31, 2010 and March 12, 2009).

The Northern Dancer deposit is one of the world's largest known tungsten-molybdenum porphyry systems. Tungsten and molybdenum mineralization are concentrated in two zones which partially overlap. The mineralization is hosted in fractures, veinlets and veins associated with a northeast-trending sheeted vein structure hosted in calc-silicate (skarn) rocks and spatially related to a felsic intrusion (quartz-feldspar porphyry). The deposit, which has been tested by drilling for 1.2 kilometres 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. 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 the northeast-trending sheeted quartz veins structure. 

Mr. Andy Campbell, P.Geo. is the Qualified Person as defined under National Instrument 43-101 responsible for the scientific and technical work on the program.
