Volume II — Technical Report of the Environmental Impact Assessment Report (REIA) for Warya Lda’s proposed heavy mineral sands mining project in Sangage, Angoche District, Nampula Province, is available for consultation. The October 2026 public consultation version describes the development, characterises environmental and social conditions in the area and assesses potential impacts during construction, operation and closure.
About the development
The project covers mining concession no. 12826C and proposes the extraction and processing of heavy mineral sands, including ilmenite, rutile and zircon, for sale in domestic and international markets.
The activities described include site preparation, topsoil removal and conservation, material extraction and transport, mineral separation, concentrate storage, and management of fine sands and tailings. The report also covers support infrastructure, water and power supply, equipment maintenance and rehabilitation of disturbed areas.
According to the document, the planned initial investment is MZN 31,067,000, presented in the study as equivalent to USD 486,357. Staffing at peak production is estimated at 158 workers, and the expected project duration is 26 years. These figures are projections from the report.
What the environmental study covers
The Technical Report brings together the project description and alternatives considered, the legal framework, and a characterisation of the physical environment, biodiversity and socioeconomic context. It examines topics including air quality, noise, soils, geology, water resources, vegetation, wildlife, land use and community activities.
The document forms part of the environmental assessment process for obtaining an environmental licence. Making this public consultation version available allows readers to examine the proposals and assessed impacts; it does not, in itself, constitute a decision approving the development.
Water, mangroves and coastal ecosystems
The topics examined include risks of altered drainage, erosion, sedimentation, deteriorating water quality and habitat disturbance. The report pays particular attention to potential interference with mangroves, wetlands, dunes and coastal vegetation, which are important for biodiversity and local livelihoods.
Proposed measures include avoiding mining in mangrove areas, establishing exclusion zones and protective buffers, preserving natural water circulation, and controlling turbidity through settling ponds. The study also recommends monitoring groundwater levels and salinity and conducting prior radiometric characterisation of the ore and waste material.
Other impacts assessed include dust emissions, noise and vibration, waste generation, fuel and oil spills, loss of vegetation cover and wildlife disturbance.
Communities, employment and land use
The study identifies opportunities for employment and local economic activity, alongside risks associated with loss of agricultural land, restricted access to natural resources, possible household displacement and effects on subsistence activities.
To address these risks, it recommends a socioeconomic survey of affected areas, identification of people who may require compensation or resettlement, and preparation of fair and participatory arrangements. The report also proposes ongoing community engagement and monitoring of fisheries resources throughout the project’s life.
Environmental rehabilitation and closure
The report recommends that rehabilitation progress alongside mining, with conservation of fertile topsoil, ground stabilisation and restoration of vegetation. Progressive rehabilitation of dune profiles and stabilising vegetation is one of the proposed measures to reduce disturbance to the coastal environment.
For the closure stage, the report examines both habitat recovery and the social consequences of declining employment and economic activity. Planning for this stage is therefore part of the assessment of the development’s impacts.
