Bel Air

  • Fully licenced and formally documented: Mining Convention, ‘Project of National Interest’, DFS, ESIA (IFC and Equator Principles)
  • The Mining Convention was signed with the Government of Guinea on the 1st February 2016 (to view press release please click here) and subsequently ratified by Parliament in June with the Presidential Decree received in July 2016. Agreeing the Convention was a significant step forward, setting out the operational regime and fiscal/tax incentives for the development of the Project
  • Extensive DFS completed – validating logistics, construction and mining plans, as well as economic model
  • Comprehensive Social and Environmental Impact Assessment Studies are ongoing to strive to ensure full IFC and Performance Standard compliance
  • Fully financed through to first commercial production having secured $205m from a consortium of international investors
  • The project has low capital requirement and operating costs due to proximity to coast and DSO production
  • High quality product with very low reactive silica
  • Initial steady state production of 5.5Mtpa, trucking DSO ore to coast for loading via transshipping barges to Capesize vessels
  • Construction commenced in January 2017 and had a relatively short construction timeframe of circa 18.5 months
  • Mining and stockpiling of ore commenced in June 2018, with First Ore on Ship achieved in August 2018.
  • The project will now ramp up to steady state over the coming months

Construction commenced in January 2017, with an official opening ceremony in February 2017 and production commenced in Q3 2018. Stockpiling began at the end of June 2018, with First Ore on Ship achieved in August. Ramp up is now in progress with an initial steady state rate of 5.5mpta.

SIMPLE LOGISTICS SET-UP:  SHORT HAUL – CAUSEWAY CONVEYORS – BARGING – TRANSHIPMENT

Direct Shipping Ore will be mined from a total of six pits. A minimum of two areas are in operation at the same time as this increases production flexibility as well as providing adequate ore blending capability.

Surface mining is being used as the mining method as this is a low opex option with simple handling and high efficiency

  • Optimised mining control
  • Significantly reduces strip ratio, waste handling and haulage costs
  • Lower fuel consumption
  • No requirement for drilling, explosives or secondary crushing required – safer mining operation
  • Improved in pit ground conditions
  • Reduced bulking factor for improved haulage facilities
  • Less dust and noise
  • Enables ongoing rehabilitation during LOM

Materials handling ensures control of dedicated logistics and facilities

  • Simple, efficient infrastructure
  • Material is transported via truck from the pits to the ROM tip at the export facility on coast
  • Ore is stockpiled and handled via conveyor over a rubble causeway and loaded onto barges
  • This serves to de-link the mining process (continuous) and barge loading (batch process)

Onshore infrastructure includes:

  • A self-contained camp and operations centre
  • Water wellfields which have been identified and designed
  • Power obtained by diesel generators
  • Dedicated communications and internet

Transhipment is the optimal method for bulk export from Bel Air

  • Transshipment involves the loading of bauxite into barges at a barge berth at the end of a causeway
    • The causeway is a simple geotechnical structure placed on bedrock (1.4km long, -3.4m CD) which provides access from the shore to appropriate water depth for a barge load-out berth
  • Self propelled barges then transport the ore to an Ocean Going Vessel at the Transshipment Zone, approx. 32km offshore
  • A Transhipment vessel then transfers the bauxite from the barges to the OGV
  • This provides an optimum balance between low capex, simplicity of operation and functionality
  • All samples collected were submitted for XRF and low temperature (150°C) bomb digest analysis; this has enabled Alufer to produce an extensive chemical database and has resulted in a thorough understanding of the available alumina and reactive silica distribution throughout the project
  • 99 representative core samples were selected from all bauxite facies (bauxite – BX, ferruginous bauxite – BXF and lateritic bauxite – BXL) for detailed bauxite characterisation
  • Analysis included density, moisture, organic carbon, XRF, bomb digest, XRD, minor oxides and trace element analysis
  • The DSO unwashed Bel Air bauxite should be easily processed as full or partial feedstock in low and high temperature refineries or for sweetening process
    Further bauxite characterisation testing revealed three types or bauxite: DSO bauxite; ferruginous bauxite; and lateritic (or clayed) bauxite. Ferruginous and lateritic bauxite can be beneficiated into export products through a process of washing and screening
