Ann: Breakthrough maiden copper discovery, page-18

@Joannie - IMO, MDI will be in production in Q3 of 2021, based on the Feasibility Study being released in January 2021, and a five-six month timeframe for plant refurbishment.

This timeframe estimate, and all of the below info is based on the announcement released on 26th October, which gives a good overview of everything:

• The majority of assay data relevant to the Feasibility Study (FS) for Middle Island’s advanced Sandstone gold project in central WA, has been received.
• Mineral Resource estimates have been completed for eight of Sandstone’s 10 gold deposits; the remaining two are in progress.
• Pit optimisations and pit designs have been completed for the first five quantified deposits; work on haul road and waste dump designs has also commenced.
• Work streams on pit geotechnics, groundwater, surface water management and water supply continues.
• Metallurgical testwork has commenced, supplementing previous testwork and operational performance.
• A concurrent scoping study into a modest upgrade to the capacity of the on-site mill has commenced with GR Engineering Services.
• Design work on additional tailings storage capacity is well advanced.
• Sterilisation drilling for new and expanded waste dumps, and a tailingsfacility expansion, will commence within days.
• Evaluation continues into the refurbishment and upgrade of the substantial existing supporting infrastructure at Sandstone.
• Environmental surveys and assessments are being completed prior to approvals submissions.
• Detailed cost estimates and FS reporting is expected to be completed in January 2021.
