Largo Commences Drilling at Its Maracas Vanadium Project, Bahia, Brazil - 11,000 Metre Drill Program Underway- Objective to Double Existing Resource

TORONTO, ONTARIO -- (Marketwire) -- 05/17/11 -- Editors Note: There are three maps associated with this release.

Largo Resources Ltd. (TSX VENTURE: LGO) ('Largo') is pleased to announce that drilling has commenced at its advanced-stage Maracas Vanadium Project in Bahia, Brazil, with two drills active on the property.

The 11,000 meter exploration drill program (see press release dated April 26, 2011) is targeting several high priority vanadium targets and has been designed with the goal of doubling the existing Mineral Resources Estimate at the project.

In addition to expanding the vanadium mineral resources at Maracas, Largo also intends to further investigate the potential for Platinum Group Metals ('PGMs') on the property. Previous exploration programs have identified a NI 43-101 compliant resource of 208,000 ounces of PGMs with significant platinum to palladium ratios of four to one.

The drill program is expected to take nine months to a year to complete and Largo will release drill results as they are received.

Andy Campbell, Vice President of Exploration for Largo, commented: 'The Maracas project has tremendous potential for further discoveries of both Vanadium and PGMs and Largo is optimistic that the present drill program will substantially expand the resource at Maracas. Although the primary focus of the exploration campaign will remain vanadium, the PGM possibilities are also quite exciting and we are looking forward to further determining the projects potential in this area.'

Mark Brennan, President and CEO noted: 'With the recent completion of the $115 million equity financing, the soon to be completed debt financing and the subsequent start of construction we anticipate that this exploration program will provide Largo the potential opportunity to expand the current scope of the project as we become a significant player in the Vanadium market. We believe there is excellent potential based on results to date that our highly skilled exploration team, led by Andy Campbell, will be successful.'
