Fort they need to do the drilling to be able to do a PEA and maybe a PFS (though not clear if this drilling is sufficient to take to PFS level)
Tandayama-America Economic Potential
The Tandayama Americana deposit outcrops at surface. The QP envisions that the TAM deposit could be exploited by open-pit mining methods. An initial assessment of TAM’s economic potential was performed by the QP, however, due to gaps in the technical data, the assessment does not meet the required standards of a PEA. Additional geotechnical, hydrologic work, waste rock characterisation, metallurgical testing and mine planning are required to accurately determine the viability of the TAM deposit at a PEA or PFS level.
The QP performed preliminary mine planning work, utilising Whittle pit optimisation shells and selected the TAM ultimate pit. Annual production schedules were developed and utilised to determine mine equipment requirements. Haulage profiles were developed on an annual basis to determine haulage fleet requirements. Equipment and fleet quotes were obtained to estimate capital requirements, and estimates were used for infrastructure requirements. The open pit at the TAM deposit may have the potential to provide ore to the mill as the underground block cave at Alpala is being developed. The QP recommends conducting the testwork required for a PEA to be completed.
Personally I think they didnt bother drilling TAM because they didnt want to spend the money. What changed.... the coastal plains TSF site proved to be unworkable so they had to go to one of the two on site. To make them work TAM becomes a lot more important because instead of using borrow pits at the TSF locations they can use the spoil generated from TAM to build the TSF. Its a lot cheaper to transport spoil than excavate from borrow pits.
