PRESS RELEASE October 26, 2017

Largo announces results of Life-of-Mine Study for its Maracás

Menchen Mine and resulting significant increase in NPV

TORONTO, ON – October 26, 2017- Largo Resources Ltd. (“Largo” or the “Company”) (TSX:

LGO) ( OTCQB: LGORF ) is pleased to announce the results of an independent National

Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) Technical Report

(the “Technical Report ”), containing a Life of Mine Plan (" LOMP") for its Maracás Menchen

vanadium mine in Bahia, Brazil (the “Maracás Menchen Mine”), a Feasibility Study (the “FS”) for

Campbell Pit at the Maracás Menchen Mine and, a Preliminary Economic Assessment (the

“PEA”) for Gulçari A Norte, Gulçari B, Novo Amparo, Novo Amparo Norte, Campbell in pit

resources and São José satellite deposits at the Maracás Menchen Mine (the “ Satellite

Deposits”).

Largo retained GE21 Consultoria Mineral Ltda. (“GE21”) to prepare the Technical Report and it

will be filed on SEDAR within the required 45-day period.

Highlights of the Technical Report:

 NPV(8%) post tax is US$ 542 million for the reserves at the Campbell Pit, representing an

increase of approximately 195% over the NPV reported for Reserves in Largo's Updated

Mine Plan And Mineral Reserve Report filed on July 8, 20161.

 NPV(8%) post tax is US$ 140 million for the mineral resources in the Satellite Deposits.

 Life of operation for the reserves in the Campbell Pit is 11 years.

 An additional mine life of 12 years was estimated, if the Inferred Resources in the

Satellite Deposits come to be converted to Mineral Reserves.

 The Technical Report is a “Vanadium Only” study. No value was given for any by-

products at this time, including iron, ilmenite ("TiO2") and PGMs.

 The Technical Report used a long-term vanadium pentoxide ("V2O5") price of US$

6.34/lb for the life of mine except for the years 2018 and 2019, where vanadium

pentoxide price of US$ 9.00/lb was used.

 The LOMP results indicate an operating life of the Maracás Menchen Mine, including the

Satellite Deposits, to be of 23 years.

 The Technical Report contemplates two expansions to increase production at Campbell

Pit as follows: in 2019-960 tonnes/month (11,520 tpa) and in 2020-1100 tonnes/month

(13,200 tpa).

1 The increase in NPV is largely the result of the increase in V205 prices and the effect of the expansion projects 

contemplated by the Technical Report. 

 The reserves in the Campbell Pit were estimated as follows:

*Numbers are rounded to one decimal place.

 GE21 recommended the Satellite Deposits be developed sequentially as follows: Novo

Amparo Norte, Gulçari A Norte & Gulçari B, Sao Jose, Campbell in pit resources and

Novo Amparo.

Mineral resources that are not mineral reserves do not have demonstrated economic

viability. The PEA is preliminary in nature and includes inferred mineral resources that are

considered too speculative geologically to have the economic considerations applied to

them that would enable them to be categorized as mineral reserves and there is no

certainty that the results of the PEA will be realized.

Overview of the Technical Report:

Largo has completed construction, development and ramping up to name plate capacity (9,600

tonnes V2O5/year) at its Maracás Menchen Mine.

The Technical Report was prepared by GE21 and was designed to allow the Company to more

fully optimize operations in order to maximize the Maracás Menchen Mine’s NPV and is based on

the production of V2O5 from the Maracás Menchen Mine’s mineral resources as well as from its

established mineral reserves. The PEA examines the incremental impact to the mine plan of

mining the Satellite Deposits not previously considered. The report does not provide any credit

for by-products, however Largo will continue to evaluate the technical and economic viability of

all potential by-products.

The Technical Report respects the definition of PEA as described in the CSA Staff Notice 43-307-

Mining Technical Report – Preliminary Economic Assessments , issued by the Canadian

Securities Administrators on Aug 16, 2012.

Mr. Smith, Largo`s CEO stated “I am very pleased with the results of this study. Both the increase

in the net present value of our operations and the greatly increased mine life that could be

achieved as a result of the Satellite Deposits speak to what I view as a very bright future for Largo.

This Technical Report further reinforces that Largo has a world class vanadium operation and I

am confident that our team will continue to meet and exceed our operational expectations.”

About Largo Resources Ltd.

Largo is a growing strategic mineral company focused on the production of vanadium pentoxide

at its Vanadio de Maracás Menchen Mine. Largo also has interests in a portfolio of other projects,

including: a 100% interest in the Currais Novos Tungsten Tailings Project in Brazil; a 100%

interest in the Campo Alegre de Lourdes Iron-Vanadium Project in Brazil; and a 100% interest in

the Northern Dancer Tungsten-Molybdenum property in the Yukon Territory, Canada.

Vanadium is primarily used as an alloy to strengthen steel and reduce its weight. Vanadium

enhanced steels are used in a vast and growing range of products that are used and encountered

every day; including, rebar, automobiles, transpor t infrastructure etc. With consumption

increasing at a compound annual growth rate of over 8% for the past several years (Roskill, 2015),

vanadium is a bourgeoning commodity which lacks opportunities for investment in the wider

market place. As trends in the steel industry now demand increasingly stronger and lighter

products for advanced applications, the use of vanadium is expected to continue this growth over

the medium and long term.

Largo is listed on the Toronto Stock Exchange under the symbol "LGO".
