Horizonte Minerals Plc: Araguaia Nickel Project - Announces Nickel/Cobalt Limonite Resources with Potential to Supply the EV Battery Market

LONDON, UNITED KINGDOM -- (Marketwired) -- 09/14/17 -- 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 the resources estimate for the nickel/cobalt limonite portion of the deposit.

Highlights


--  The limonite Mineral Resources, in the Measured and Indicated category,
    are 20.7 million tonnes grading 1.13% Nickel and 0.12% Cobalt (0.9%
    nickel cut off) 
--  The limonite Measured and Indicated Resources are estimated to contain
    233,200 tonnes (515 million pounds) of nickel and 25,580 tonnes (56
    million pounds) of cobalt 
--  Resources do not form part of the mine schedule, nor the financial model
    for the RKEF plant currently the focus of the Feasibility Study ('FS') 
--  Additional potential within the overall project area to expand these
    limonite resources 

Horizonte CEO Jeremy Martin said, "We are pleased to announce the limonite Resources at the Araguaia Project. The processing of these Resources is not part of the current mine plan in the Feasibility Study ('FS') for the Rotary Kiln Electric Furnace project ('RKEF'). In the FS, the plan is to extract and stockpile the limonite resources on the surface; however, the stockpile contains over 230,000 tonnes of nickel and 25,000 tonnes of cobalt which are not currently included in the cash flow model for the Araguaia RKEF project.

"We are mindful of the future potential value of this material so as part of the current mine plan it will be mined and stockpiled separately based on mineralogy and nickel / cobalt grades. The limonite cannot be processed using RKEF process so it will require an alternate process technology. The material will be located in a permitted mine site with all infrastructure in place so it represents a low cost source of nickel and cobalt that has the potential to add significant upside to the overall operation, and at the appropriate time, the Company may decide to advance economic studies on its nickel / cobalt production potential. The Company's current focus remains on the existing FS for the RKEF plant, but these limonite resources provide the potential to establish a second, complimentary project on the same site in due course. It should also be highlighted that there is potential within the overall project area to expand these preliminary limonite resources with additional exploration work.

"In other parts of the world, limonite resources are treated to produce products, such as nickel and cobalt hydroxides; suitable for supplying the electric vehicle (EV) battery market. Demand for nickel and cobalt is expected to accelerate over the next 5-10 years as EV battery production ramps up. China has the most ambitious EV growth goals in place, targeting 5 million EVs on the road by 2020 and production of 7 million by 2025. There are three principal battery types to consider when looking at the EV market: lithium-cobalt-oxide (LCO), nickel-manganese-cobalt (NMC) and nickel-cobalt-aluminium-oxide (NCA); all of which could utilize nickel or cobalt from Horizonte's limonite resource, given the right extraction and processing of these metals.

"This new development positions Horizonte with exposure to the fast-growing nickel/cobalt EV battery market. With our planned RKEF plant able to produce ferro nickel for traditional use in the stainless-steel industry, the limonite resources at Araguaia have the potential to supply substantial nickel and cobalt products into the EV battery sector.

"We are working towards publishing the Feasibility Study by the end of Q4 2017/Q1 2018, while we review process options for the limonite material and look at the upside that could be added to the advanced Araguaia Project."

Further Details

At a 0.90% nickel cut-off grade the estimated limonite mineral resources in the Ara South deposits (Baiao, Pequizeiro, Pequizeiro West, Jacutinga, Vila Oito, Vila Oito West, Vila Oito East) and the Ara North deposit (Vale dos Sonhos) are estimated and reported in the Pre-Feasibility Study (PFS) (Sept 2016) are presented in Table 1.

The Mineral Resources reported in the September 2016 PFS, from which Table 1 is extracted, were prepared under the supervision of Mr. Andrew F. Ross BSc (Hons), MSc, FAusIMM, an Independent Qualified Person as defined in NI 43-101.

A total of 40,330 meters (1,494 holes) from ARA South and 28,860 meters (839 holes) from ARA North were used in the Mineral Resources Estimation reported in the PFS.

The Araguaia Nickel Project

Araguaia, which is 100% owned by Horizonte, is located on the eastern margin of the State of Para, north-eastern Brazil, in the Municipal of Conceicao do Araguaia (population of 46,206), south of the main Carajas Mining District.

The Project has good regional infrastructure including a network of Federal highways and roads, with access to low tariff hydro-electric power. The Carajas Mining District, situated approximately 200km northwest of Araguaia, is host to a number of major iron and copper mines operated by mining major Vale SA.

The PFS released in October 2016 considers open pit mining for the exploitation of nickel laterite to establish the production of run of mine ('ROM') from eight open pits to supply a targeted 0.9 million tonnes per annum ('Mt/a') of ore to a processing and smelter facility. This facility will use the proven RKEF process with the product being sold free on board ('FOB') at the selected port of export.

A Base Case of 0.9 Mt/a production throughput was selected because of the Company's objective to minimise the capital expenditure and overall capital intensity, and to optimise overall cash flow, payback, and the economics of the Project.
