DSO Project

DSO Project
(Avenira – 100%)

Avenira continues to progress the Wonarah Direct Shipping Ore (DSO) Phosphate Project, which aims to mine and sell high-grade phosphate ore from its Tier 1, 100% owned Wonarah Phosphate Mine. The Project is designed as a simple open cut, low capital mining operation.

Key highlights include:

  • Northern Territory Government issued Mineral Leases, ML33343 and ML33344, required for the DSO Project.
  • Mining agreement with the Arruwurra Aboriginal Corporation (AAC) finalised and executed.
  • Feasibility Study has been completed and shows good low cost economics. 
  • Mine Management Plan (MMP) approved for initial 40,000t ore parcel.
  • MOU executed with a regional Yellow Phosphorous producer working towards trial mining and downstream process development.
  • MMP for additional 1.2Mt of ore extraction lodged with DITT and undergoing assessment
  • Negotiations for the logistics operation of the project are continuing, including discussions with Aurizon for rail haulage and Port of Darwin for storage and logistics.
    Activity

Wonarah has access to good quality existing infrastructure:

  • Access to established bulk commodity port at Darwin
  • Adjacent to priority highway Barkly Highway
  • Proximity to railway with spare freight capacity Tennant Creek to Darwin
  • Natural gas pipeline adjacent to Wonarah tenements
  • Highly suitable for solar energy, located in Australia’s highest photovoltaic region

Wonarah mineralisation lies within late Proterozoic to early Palaeozoic sedimentary rocks of the Georgina Basin which hosts several phosphate deposits in eastern Northern Territory and western Queensland. Wonarah is located in the area of a basement high between the Barkly and Undilla Sub-basins.

 

Mineralisation at Wonarah is contained within the Upper Gum Ridge Formation, comprising several units with varying degrees of phosphorite mineralisation.  The most prolific mineralisation is within the Mudstone Phosphorite Unit (MPH), with varying degrees of mineralisation in the underlying units within the Upper Gum Ridge Formation.

Avenira has an extensive tenement portfolio which extends well beyond the existing Wonarah resource.  Some of this portfolio has been drilled at a broad spacing and contains intercepts of >27% P2O5. This will allow Avenira to support long operations associated with beneficiation, downstream YP and TPA.
