HORIZONTE COMMENCES SOCIAL & ENVIRONMENTAL BASE LINE WORK ON THE RECENTLY ACQUIRED GLENCORE ARAGUAIA NICKEL PROJECT

_____________________________________________________________________

15 September 2016 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') the London and Canadian listed nickel development company focussed in Brazil, is pleased to announce that it has commenced social and environmental base line data collection on its recently acquired Glencore Araguaia Project ('GAP'), the adjacent nickel project to the Company's Araguaia Project ('Araguaia'). The consolidation of Araguaia with GAP (together 'the enlarged Araguaia Project') has created one of the largest nickel saprolite projects globally and the Company is currently in the process of finalising an updated Pre-Feasibility Study on the enlarged Araguaia Project.

Summary

· Leading Brazilian sustainability consultants, including Brandt Meio Ambiente, have commenced social and environmental baseline data collection for the Vale dos Sonhos target, which is one of the principle nickel deposits recently acquired by Horizonte.

· The collection of baseline data for the Vale dos Sonhos deposit is an important step to integrate GAP into the environmental permitting process underway at Horizonte's advanced Araguaia Project, which was successfully awarded the Preliminary Licence ('LP') earlier in 2016

· New GAP baseline data collection together with further advancements to existing social and environmental impact assessments on the Araguaia project, is an important milestone to progress towards the Installation Licence, which is the final permit required before construction can commence at the enlarged Araguaia Project

Horizonte CEO Jeremy Martin said, "Following on from the recent award of the Preliminary Licence at Araguaia and conclusion of the Glencore Araguaia Project acquisition, I am pleased to announce that work is underway to bring GAP into alignment with our development schedule in terms of environmental and social permitting. The next step is the award of the Installation Licence ('LI') on the Araguaia Project allowing construction to start.

"We are pleased to be working with Brandt Meio Ambiente, one of the leading environmental and social consulting groups in Brazil who have been involved in a number of major mining projects in the Carajás region. I look forward to updating the market with results from our new Pre-Feasibility Study which is due imminently."

Further Details

The historic work completed on GAP, in partnership with consulting group Golder, has provided Horizonte's team with an excellent base to conduct a full social and environmental baseline programme that meets both Brazilian and International best-practice guidelines.

Brandt Meio Ambiente was successfully awarded the contract to conduct initial baseline data analysis for GAP. Brandt has a proven track record in permitting Brazilian nickel projects and also has recent experience in permitting projects in the neighbouring Carajás mining district in the Pará State.

Specialised biology consultant, DBO has been awarded the contract to undertake future fauna and flora studies at GAP and to further extend existing fauna and flora studies in the Araguaia deposits.

Integratio was the consultant responsible for undertaking the social impact assessment for the Araguaia project. Integratio has provided new social baseline data for Xinguara Municipal, the local government area containing the Vale dos Sonhos deposit. This socio-economic data will be incorporated into the new Pre-Feasibility Study which is due imminently and will be included in future assessments for Brazilian environmental permits in relation to the Vale dos Sonhos deposit.

Additional consultants will be contracted for laboratory analysis and specialised studies as set out in the Pará Environmental Agency (SEMAS) terms of reference.

The Preliminary Licence ('LP') for Araguaia was approved in May 2016 with consideration of the terms set out in the Company's Social & Environmental Impact Assessment, and conditions outlined by SEMAS. Once the Installation Licence is awarded in parallel with the mining concession, construction may start.

The objective of the new social and environmental baseline data programme at GAP is to integrate the Vale dos Sonhos deposit into the advanced permitting schedule for the enlarged Araguaia project.
