Considerations and potential economic advantages for …

The typical deposit depth lends itself to ISR processing with paleoplacer gold deposits having been mined at depths of up to 3 km. For conventional operations, ore deposits at this depth may require relatively high gold grades to be economic (of the order of 5–15 g/t), whereas an ISR process could possibly be applied to lower-grade deposits.
