VANCOUVER, British Columbia, Oct. 01, 2021 (GLOBE NEWSWIRE) — Macarthur Minerals Limited (ASX: MIO) (TSX-V: MMS) (OTCQB: MMSDF) (the Company or Macarthur) is pleased to provide an update on the solid progress being made on the Feasibility Study for its high-grade magnetite Lake Giles Iron Project. The metallurgical process test work and the non-process infrastructure design for the Feasibility Study is complex but has now moved past 60% design completion. The balance of the work required to complete these components of the study is now expected to run at an accelerated pace from this point forward.
The following summary sets out details of current progress on both metallurgical process design and non-process infrastructure design as the Feasibility Study advances closer to completion.
Metallurgical Process and Non-Process Infrastructure Progress Highlights
- Metallurgical process test work and process flow sheet design:
- The metallurgical test work is advancing and is approximately 60% complete
- Final LIMS tests have been conducted with assays pending
- Magnetic and reverse flotation test work is now being undertaken
- HGPR sample test work is being scheduled
- Process engineering and design work for flow sheet is advancing and is over 60% complete
- Non-process infrastructure (NPI) work:
- The NPI works package is advancing with a 60% design milestone reached
- The Stantec (Engenium) team is heavily engaged in design works for all support infrastructure encompassing the bore field, mine village, airport, haul road, water desalination plant, solar power plant, mining infrastructure, and the rail siding
- 3D design of the tailings storage facility and evaporation ponds is currently in progress with preliminary geotechnical analysis completed for sourcing onsite construction materials
- Detailed LiDAR data has been obtained and will be utilized to improve current hydrological modelling of the project catchment to ensure adequate design and protection of critical logistics infrastructure
- An electrical load list for both process and non-process infrastructure has been completed to support power configuration and optimisation analysis

The current geotechnical drilling programme of works is nearing completion with a target end date of 22 October 2021. The drill programme has exceeded the original target end date of the end of September with the contributing factors including wet weather and challenging ground conditions. Following completion of the drilling work, the core samples will be submitted to the lab for assessment prior to the data being used to finalise the mine planning work being undertaken by Orelogy. Although the extended drilling period may moderately affect the timeline for mine planning in the study schedule, the overall resultant impact is not currently anticipated to be material.
The Company now anticipates providing, at a minimum, fortnightly updates on Feasibility Study progress in the lead-up to the completion of the Study and the delivery of the final study outputs to the market. Upcoming news releases will provide an update on the material progress that has been made on numerous aspects of the study including rail and port logistics and mine planning.
Andrew Bruton, CEO of Macarthur Minerals commented:
“Management is pleased with the solid gains being made in the advancement of the Feasibility Study. Ensuring the highest quality results from the process is paramount.
The study is advancing towards a conclusion now, and the next few months should see the rapid completion of the fundamental body of works required to complete the final Feasibility Study reports and the detailed economic model for the project so that the key financial outputs can be presented to the market and potential funders.
Macarthur is encouraged by the work and quality of the outputs being achieved by its consultants as they progress towards completion of the Feasibility Study. Management looks forward to releasing further details of material progress milestones by way of regular updates over the coming weeks.”
