HORIZONTE ANNOUNCES VERMELHO MINERAL RESOURCE CONFIRMING SIGNIFICANT NICKEL AND COBALT INVENTORY

_____________________________________________________________________

09 May 2018 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') the nickel development company focused in Brazil which is developing the Araguaia nickel project as Brazil's next ferro-nickel mine, is pleased to announce an initial NI 43-101 Mineral Resource Estimate for the recently acquired Vermelho nickel/cobalt project.

Highlights

· The Vermelho Nickel-Cobalt Mineral Resources, in the Measured and Indicated category, are 167.8 million tonnes grading 1.01% nickel and 0.06% cobalt (at 0.9% nickel equivalent cut off)

· The Measured and Indicated mineral resources categories are estimated to contain 1.68 million tonnes (3,700 million lbs) of nickel and 94,000 tonnes (207 million lbs) of cobalt

· The Mineral Resource Estimate places the Vermelho project as one of the largest, highest grade undeveloped laterite nickel - cobalt resources globally

· Significant portion of high grade saprolite within the deposit is amenable to the Rotary Kiln Electric Furnace process route to produce ferronickel being developed at the Araguaia project

· Test work planned to confirm the Vermelho mineralisation is suitable to produce nickel and cobalt sulphate for the EV battery Market

Horizonte's CEO Jeremy Martin said, "This NI 43-101 Mineral Resource covering the Vermelho nickel-cobalt project is an exciting development for the Company. The resource is high grade, at around 1.34% NiEq% and places the project on the upper end of the global grade curve as well as being scalable, adding over 1.6 million tonnes of contained nickel and over 90,000 tonnes of contained cobalt to the Company's substantial global metal inventory.

The next phase of work at Vermelho will focus on advancing the work that Vale completed as part of their Feasibility Study, taking the mixed hydroxide product (MHP) and upgrading to nickel and cobalt sulphate suitable for use in the evolving EV battery market. The acquisition of the Vermelho nickel - cobalt project means that Horizonte now has the potential to supply both high grade ferro-nickel from the Araguaia project to the stainless steel market and nickel/cobalt products from Vermelho that can be used in both the EV battery market or the metals space as we work towards becoming a leading nickel development company.

 The current focus at the Araguaia ferro-nickel project is the completion of the Feasibility Study and the work related to the award of the construction licence. We look forward to keeping the market updated as we advance both projects against a backdrop of strengthening nickel and cobalt prices, where recent nickel prices have been in the US$ 6-7/lb range and cobalt prices continue to trade above US$40/lb, driven by a combination of growing demand, as highlighted by recent Chinese EV numbers and concern around cobalt supply restrictions in the DRC" 

Further details

Horizonte's 100% owned Vermelho Nickel-Cobalt project was acquired from Vale in late 2017, it is located in the eastern part of the Carajas mining district and approximately 80 kilometres north west of the Company's Araguaia North ferro-nickel project.

At a 0.90% nickel-equivalent cut-off grade the estimated Nickel-Cobalt mineral resources in the Vermelho ('V1') and Vermelho ('V2') deposits are presented in Table 1. The Mineral Resource is reported by a series of nickel equivalent cut-offs in 2018 from Gemcom mining software. The basis of the nickel equivalent calculation is the equation NiEq% = Ni% + (6 x Co%), based upon the relative average cash prices for nickel and cobalt metals, as reported on the London Metal Exchange for the six-month period 2nd November 2017 to 3rd April 2018. The nickel equivalent calculation assumes similar nickel and cobalt recoveries as obtained by the test work carried out by Vale in the Feasibility Study.

Mr. Andrew F. Ross MSc, FAusIMM, an Independent Qualified Person as defined in National Instrument 43-101 - Standards of Disclosure for Mineral Projects ('NI 43-101') employed by Snowden Mining Industry Consultants, has completed a review of this Mineral Resource Estimate and has recommended to Horizonte that this Mineral Resource Estimate is suitable for reporting by Horizonte as the current Mineral Resource Estimate. These Mineral Resources were reported to Horizonte as current Mineral Resource Estimates, after Snowden reviewed the historic mineral resource estimates described in the NI 43-101 Technical Report dated 1st February 2018. The mineral resource categories (Measured, Indicated, Inferred) conform to the requirements of the JORC Code (2012) which is a permitted reporting code under NI 43-101.

A total of 77,575 metres (1,383 holes) from V1 and 51,165 metres (877 holes) from V2 were used in the evaluation of the deposits and Mineral Resource Estimates reported in the Vermelho Feasibility Study.

Note: Totals may not add due to rounding. Mineral resources which are not mineral reserves do

not have demonstrated economic viability. The estimate of mineral resources may be materially

affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other

relevant issues. The quantity and grade of reported Inferred resources in this estimation are

uncertain in nature and there has been insufficient exploration to define these Inferred resources

as an Indicated or Measured mineral resource and it is uncertain if further exploration will result

in upgrading them to the Indicated or Measured mineral resource category.
