Largo Resources Completes Drill Program at Novo Amparo Norte in Maracás and Extends Vanadium Zone by 130% to 1.84 km in Strike Length

• Extensive 25,000 metre exploration program planned for 2019 on several targets near Campbell Pit including additional drilling at Novo Amparo Norte

TORONTO, Dec. 19, 2018 - Largo Resources Ltd. ("Largo" or the "Company") (TSX: LGO) (OTCQX: LGORF) is pleased to announce that it has completed the second phase of drilling at the Novo Amparo Norte ("NAN") deposit. NAN lies approximately 6.5 km north of Largo´s current mining operation at the Campbell Pit at its Maracás Menchen Mine and is the most northern zone of mineralisation identified at the Maracás Project.

Key Highlights Include:

• 1.18% V₂O₅ over 18.76 metres (true thickness of 13.10 metres*) in hole FNAN-26
• 1.12% V₂O₅ over 19.53 metres (true thickness of 14.46 metres*) in hole FNAN-31
• Extends NAN mineralisation to approximately 1,840 metres and remains open, being
  an increase of approximately 130%

At NAN 24 NQ diamond drill holes were completed in 2018 totalling 4,223 metres. In total, 1,556 samples were collected and sent out for analysis for grades of V₂O₅ (%) and other selected elements at the SGS Laboratory in Belo Horizonte, Brazil. This press release summarizes the results from the first 20 holes (1,221 samples) of the current drill program that have been received to date. The results for the remaining 4 holes are expected by the end of December. Table 1 below outlines significant drill intercepts from the 2018 drill program at NAN.

Mark Smith, Chief Executive Officer for Largo, stated: "Largo is committed to increasing its mineral resources and reserves in support of developing new feed sources in the short-term for current mining operations at the Campbell Pit and for potential future expansion of operations at the mine. The drill results at Novo Amparo Norte have exceeded our initial expectations and reinforce our view that Maracás continues to have tremendous potential.  We are pleased to have completed this phase of the drilling and are eager to begin the next phase of exploration to reveal the true potential of Maracás."

Previous drilling at NAN completed by Largo (2011-2012) outlined a consistent zone of mineralisation over 790 metres with an average width of 18 metres and an average grade of 0.87% V₂O₅. The current program has been successful in extending mineralisation both to the north and south along strike to approximately 1,840 metres and remains open to the south and to depth.  Figure 2 shows the collar locations from the historic drilling and the most recent drill program.

Largo also carried out Davis Tube analysis on selected samples from the prior drill campaign at NAN.

Preliminary 3D geological interpretation (Figure 3) indicates mineralisation has been intersected over a strike length of 1,840 metres.  The zone is open along strike and remains open to the south and at depth.  Largo plans to complete an initial resource estimate at NAN in the first quarter of 2019 once all assay results have been received.

2019 Drill Program

Largo is forecasting an extensive exploration drill program that will be completed over the next two years targeting NAN and the majority of the other known mineralised targets in the vicinity of the Campbell Pit.  It is anticipated that the 2019 exploration drill program will consist of approximately 25,000 metres of diamond drilling and supporting work.

Vanadium Outlook

It is Largo's view that the recent dip in vanadium prices to US$23.50-24.00/lb¹ do not reflect what we believe to be the overall fundamentals of the market which have remained largely unchanged and, in Largo's view, continue to show a structural supply deficit for the foreseeable future. Vanadium prices are up approximately 156% compared to the same period last year. Largo continues to expect an elevated pricing environment for vanadium that will continue to remain in place until new supply is brought online.

Quality Assurance and Quality Control

All drill core samples were delivered to the SGS facility in Belo Horizonte, Brazil for analysis of select elements by XRF79C. Davis Tube test work is carried out on all mineralised samples. Quality control entailed the insertion of company blanks and standards into the drill core sample stream. In addition, SGS routinely inserts blanks, standards and duplicate analysis.
