Yongala
Undrilled historic copper workings over a regional copper-bearing shale, with rare-earths potential.
Sediment-hosted copper province
Yongala covers the shale unit that hosts sediment-hosted copper elsewhere in the region, an under-explored setting here. Mondo's own sampling found historic copper workings that have never been drilled, and potassic intrusions point to possible rare-earths mineralisation.
Never drilled
Historic workings with high-grade copper and silver in rock chips.
Under-explored host
The regional copper host shale is barely tested in this area.
Two commodities
Copper plus a possible rare-earths system.
Geological setting
Sediment-hosted copper in reduced shale units, with vein-style copper-silver at historic workings. Potassic intrusions may carry rare earths.
Drill results, historical estimates, tenement schedules and budgets are available to eligible wholesale investors in the data room, under a confidentiality agreement. Exploration information is historical or preliminary and is not reported under the JORC Code (2012). See the important notice.
How we plan to advance it
The program is staged. Each step is funded only if the previous one justifies it.
Mapping
Map the shale unit and historic workings.
Rock sampling
Systematic sampling along strike.
Data work
Compile open-file data and rank drill targets.
How value is realised
Yongala adds a South Australian copper position to the copper vehicle, alongside further opportunities Mondo is reviewing in the state.
Listing
Vended into the planned copper company for equity.
Joint venture or option
A partner funds work to earn an interest.
Sale or royalty
Sold outright, with Mondo keeping a royalty.
