NEW HIGH GRADE DRILL RESULTS AND OPERATIONS UPDATE FROM THE ARAGUAIA NICKEL PROJECT, BRAZIL

26 January 2015 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') the nickel development company focused in Brazil, is pleased to announce new high grade drill intersections from recent bulk sampling drilling and provide an update on the ongoing work related to the Feasibility Study at its 100% owned Araguaia nickel project ('Araguaia') in Para State, north central Brazil.

Highlights

 High grade nickel assay intersections received to date for the first 15 holes from the bulk sample drilling include (all results in table 1):

o 12.47 meters grading 2.17% Ni o 12.45 meters grading 2.13% Ni o 13.35 meters grading 2.07% Ni o 13.95 meters grading 1.99% Ni

 Drill programme on schedule with 113 Diamond holes drilled (2,188 meters)

completed.

 Further infill drilling results due from the Pequizeiro Deposit where drilling is currently underway

 Significant progress made on the Environmental and Social work for Araguaia

- Public Hearing process for the preliminary environmental licence is imminent

 On track to commence bulk sampling collection early February 2015 with a 200 tonne bulk sample to be used to feed a continuous large scale pilot plant in Q2

2015 with initial dryer/agglomerator commissioning and trials commencing by

Horizonte CEO Jeremy Martin said, "We are making good progress on the Feasibility work at Araguaia with the drilling and collection of the 200 tonne bulk sample running to schedule. The drill results received from the bulk sample sites confirm the high nickel grades that are scheduled for the early part of Araguaia's mine life. The next major step will be the running of the pilot programme with the aim of confirming the detailed design parameters around the Rotary Kiln Electric Arc Furnace process and the production of nickel.
"Despite the current challenging market conditions, the Company is on track to deliver the planned milestones during 2015; we have a solid funding position; and the ongoing results from Araguaia continue to deliver. The fundamentals behind the nickel markets over the next 24 to 36 months from consensus forecasts are positive. This combined with the use of a proven processing route (RKEF) to produce ferronickel and Araguaia's favourable mining jurisdiction make a strong investment case for our flagship development project. I look forward to providing further updates throughout the year as we move Araguaia through the Feasibility process."

Further Details

Drilling

The drilling programme which will support and form part of the Feasibility Study on Araguaia started in November 2014 and is progressing well. Seven drill rigs are currently employed on this programme and 113 HQ3 Diamond holes comprising 2,188 metres have been completed to date. The programme consists of three parts:

1) Testing of Selected Bulk Sample Sites: Drilling is complete for a total of 64 holes and 944 metres, and partial results have been received and are presented in Table 1 below. Drilling was completed on 4 meter grids over four selected sites.

2) Infill Mineral Resource Drilling: Infill drilling on 50m x 50m grids is planned on selected parts of the Pequizeiro, Baião, Jacutinga and Vila Oito deposits. To date 49 holes totalling 1,244 metres have been completed on the Pequizeiro deposit the results of which are awaited.

3) Additional Geotechnical and Hydrogeological Drilling: This drilling work will be undertaken in March 2015.

NSI: No significant intersection

The compositing of the nickel grades in the individual holes was completed across geological boundaries using a nickel cut-off of 1% with a minimum intercept length of
2.0 metres and a maximum length of internal waste of 2 metres. All holes were vertical and, as these nickel laterite deposits are essentially flat-lying, all widths given are true widths. Core recoveries in the mineralised sections met the appropriate standards for this style of mineralisation and were generally >90%.

Sample preparation and analyses

Samples from drill core were crushed and pulverised at the ALS laboratory in Goiania and the resultant pulps analysed at the ALS laboratory in Lima, Peru using tetraborate fusion and X-Ray Fluorescence ('XRF'). Full QA/QC procedures were followed, including the insertion of standards, duplicates and blanks. Check samples

representing approximately 5% of all the samples will be sent to another international laboratory for analysis by XRF.

Bulk Sampling

Preparations are at an advanced stage for the collection of a 200 tonne bulk sample to provide feed for RKEF pilot plant metallurgical testwork planned for Q2 2015. The results of the pre-sample collection drilling described above will be used for the precise siting of the wide diameter auger holes to be used for the sample collection. The wide diameter auger drilling is scheduled to commence in February 2015.

Pilot Plant RKEF Metallurgical Testwork

In preparation for the pilot plant testwork scheduled for Q2 2015 at the IGEO testwork facility at Morro Azul, Minas Gerais State, initial dryer/agglomerator commissioning and trials are scheduled to commence by the end of January 2015. A 20 tonne sample for this commissioning has been selected from a previously collected (September
2011) bulk sample and despatched to the testwork site.

Environmental and Social Permitting

The Environmental and Social Impact Assessment was finalised and the report was submitted to Brazilian State licencing authority (SEMA) in Q3 2014 for Araguaia's preliminary licence evaluation. The next stage is the Public Hearing which is scheduled to take place in Q1 2015.
As part of the permitting process, the Company has consulted with a large portion of the local community and other stakeholders in the last three months to ensure the Araguaia Project will have a net positive impact on the local communities delivering sustainable value over the long term. Engagement and consultation was undertaken with local community leaders, elected local government ministers and elected state government ministers amongst other stakeholders to develop positive relationships with Horizonte as the project progresses to the feasibility study stage.
The Company continues to value the environment, through rehabilitation programmes of drill sites, ad-hoc environmental education with community neighbours, responsible use of water and its recycling programme.

About Horizonte Minerals:

Horizonte Minerals plc is an AIM and TSX-listed nickel development company focused in Brazil, which wholly owns the advanced Araguaia nickel laterite project located to the south of the Carajas mineral district of northern Brazil.
The Company is developing Araguaia as the next major nickel mine in Brazil, with targeted production by late 2017 early 2018.
The Project, which has excellent infrastructure in place including rail, road, water and power, has a current NI 43-101 compliant Mineral Resource of 71.98Mt grading 1.33% Ni (Indicated) and 25.4Mt at 1.21% Ni (Inferred) at a 0.95% nickel cut-off; included in Resources is a Probable Reserve base of 21.2Mt at 1.66%Ni.
A Pre-Feasibility Study has been completed which underpins the robust economics of developing a mine with a targeted 15,000tpa nickel in ferro-nickel output with a 20% Fe-Ni product over a 25 year mine life utilising the proven pyrometallurgical process of Rotary Kiln Electric Furnace technology. At these production rates, the project has a post-tax NPV of US$519m at a discount rate of 8% and an IRR of 20%, with a capital cost of US$582m which puts this project in the lowest quartile of the cost curve.
Horizonte has a strong shareholder structure including Teck Resources Limited 38.5%, Henderson Global Investors 14%, Anglo Pacific Group 7%.
