NEWS RELEASE 08 JUNE 2016

HORIZONTE MINERALS PRELIMINARY LICENCE GRANTED FOR ARAGUAIA NICKEL MINE & BENEFICIATION PLANT 08 June 2016 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') is pleased to announce that is has been granted a Preliminary Environmental Licence ('LP'), for the mining and beneficiation plant to produce ferronickel, for its Araguaia Nickel Project ('Araguaia') by the Brazilian Pará State Environmental Agency ('SEMAS'). The LP, granted to Horizonte's wholly owned subsidiary, Araguaia Níquel Mineração Ltda., is a significant milestone which demonstrates the viability of Araguaia and represents the State Government approval for the planned Project. Overview

• The granting of Preliminary Licence demonstrates Pará State government's confidence in the credibility and viability of the Araguaia Nickel Project
• Araguaia viewed as a key economic driver for the southern part of Pará by the State government
• As a result of the award of the LP, Horizonte can now progress work towards the Installation Licence, permitting construction of Araguaia

CEO Jeremy Martin commented, "This major milestone brings Horizonte another step closer to developing Brazil's next major nickel mine. Following 24 months of work the award of the Preliminary Licence demonstrates the Pará State Government's support for the development of the Araguaia Nickel Project.

"The project has the potential to provide approximately 1,100 jobs in the construction phase, and around 500 jobs during the operational phase of the mine; as a result the Pará State Government considers Araguaia to be a key economic driver for the southern part of the State. We have also received strong community support for the project as evidenced in the 2015 Public Hearing in Conceição do Araguaia.

"The award of the LP is timely as we are in the final stages of preparing a new Pre-Feasibility Study. This new PFS will include a revised Mineral Resource covering the recently acquired Glencore project combined with infill resource drilling results, data from the full scale metallurgical pilot plant campaign completed in Q3 2015, and updated capital and operating costs. We aim to release the new PFS in H2 2016 and when viewed in tandem with the nickel market fundamentals for the next 12 to 24 months, provides a compelling investment case as we work towards developing Araguaia to Feasibility."

Detailed Information

The Preliminary Licence ('LP') was approved with consideration of the terms set out in the Company's Social & Environmental Impact Assessment, and conditions outlined by the Pará State Environmental Agency. This follows the unanimous approval of the licence in a meeting held in the Pará capital of Belém on 23 May 2016, by the Pará State Committee of Environment ('COEMA'), which consisted of State Government ministers, NGOs and representatives from civil society groups.

The Brazilian mine permitting process with environmental agencies has three key stages:

1. The recently obtained preliminary licence ('LP');

2. The installation licence ('LI'), which permits the start of construction;

3. Finally the licence to operate once construction is complete ('LO').

The granting of the LP is often regarded as the most important licence as it outlines the parameters of the project as agreed upon by all stakeholders and is the only environmental licensing process that requires COEMA approval.

The Company will now focus on obtaining the LI which once awarded, in parallel with the mining concession, allows construction to start. The LI will require further detailed environmental studies, a Definitive Feasibility Study, and further community engagement. The Company will also work in partnership with the State Government of Pará to undertake studies identifying possibilities for use of the slag product from Araguaia and potential local industries which could benefit from the final ferronickel product.
