Largo Resources Substantially Upgrades Mineral Resources at its Novo Amparo Norte Deposit in Maracás, Brazil

TORONTO, June 11, 2019 - Largo Resources Ltd. ("Largo" or the "Company") (TSX: LGO) (OTCQX: LGORF) is pleased to announce an update on the Novo Amparo Norte deposit ("NAN") in Maracás, Brazil.

Highlights of the updated resource estimate for NAN:

• Total Measured and Indicated Mineral Resources Ltd. of 12.23 million tonnes grading 0.88% V₂O₅ with magnetic concentrate grades of 2.41% V₂O₅
• Inferred Mineral Resources Ltd. of 11.33 million tonnes grading 0.90% V₂O₅ with magnetic concentrate grades of 2.46% V₂O₅
• The resource is defined over a strike length of approximately two kilometers and remains open to the south and at depth

The Company's previously announced exploration program has successfully delivered a significant increase to the overall resource base at NAN with the successful conversion of resources from the Inferred category to the Measured and Indicated categories in addition to increasing the Inferred Resources. The updated resource estimate is based on approximately 12,912 m of diamond drilling over 88 holes (including 5,404 m in 47 drill holes completed in 2019) and 5,549 sample intervals across the deposit. NAN is located approximately 6.5 km north of the Company's current mining operation at the Maracás Menchen Mine, Campbell Pit and has a lower royalty burden than that associated with the Campbell Pit.

Novo Amparo Norte Mineral Resource Estimate as of May 31, 2019

NAN lies within the Rio Jacaré intrusion, a mafic to ultramafic intrusive complex that hosts several vanadium rich titanomagnetite deposits including the Maracás Menchen Mine, Campbell Pit (Figure 1). Drilling at NAN was completed over a strike length of approximately two kilometers and the current resource estimate extends to approximately 250 meters below surface where mineralization remains open for further exploration. Vanadium rich magnetite units extend south of the current NAN resource area and the Company is evaluating future drilling plans.

Mark Smith, Chief Executive Officer of Largo, stated: "I am very pleased that through our modest drill program completed over the past year, the Company was able to successfully deliver a significant conversion of resources from the Inferred to the Measured and Indicated categories at NAN. In addition, in adding more Inferred mineralization to the total, we have further confirmed our confidence in NAN as a target for further development. We are continuing to advance our work at NAN with geological and engineering studies currently underway to further upgrade our understanding of the deposit and related economics."

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 mineralized 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.
