and Sustainability Minister of the Pará State, Luiz Fernandes Rocha, and the Mayor of
Conceição do Araguaia, Valter Rodrigues Peixoto, amongst others.
The Public Hearing is a key part of the Brazilian environmental license process, necessary to obtain the Preliminary License (LP). The aim of the event was to inform, clarify and encourage further community participation in project planning for the Municipal of Conceição do Araguaia where mining and mineral processing will occur.
The Araguaia Project is planned as a long life operation creating approximately 450 direct jobs in the operational phase of the mine. The Company seeks to be a partner- of-choice with the local community in the development of the Project to ensure long- term sustainable benefits are received by local stakeholders. Key socio-economic programmes planned for the region include initiatives for public health, environmental education, local government capacity building and economic development. The economic development programme will focus on maximising local employment as well as the development of local suppliers and small regional enterprises.
As part of the permitting process, the Company has consulted with a large portion of the local community and other stakeholders in the past 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 stage.
The Social and Environmental Impact Assessment of the area aims to identify, predict, interpret and inform society of the potential effects of activities on the health and well-being of the population as well as on ecosystems, so that the results are presented adequately to the public and environmental authorities, and then duly considered. To assess these impacts, Horizonte, in partnership with specialist environment and social consultants undertook environmental and social baseline data collections. The environmental baseline programme included information on climate, particulate matter, groundwater composition and depth, soils, surface water composition and flow, spring locations, and fauna and flora. The social baseline data collection programme included information on regional demographics, stakeholders,
livelihoods, community infrastructure, cultural heritage, natural resource use, labour

and working conditions, vulnerable groups, land rights, regional medical and emergency services, public safety, traffic volume and archaeological sites.
