Ann: Dynamic Modelling Produces Outstanding Results at Rincon, page-54

"The production simulations show brine abstraction for 12,000tpa lithium carbonate production can be sustained for 42 years and brine abstraction for 24,000tpa can be sustained for 22 years. The development of third-party projects on the Salar del Rincon may affect both the number of bores required to maintain a specific production rate and/or restrict the annual production rate such that it takes longer to recover the brine resources contained within Argosy’s project. Regardless, it is simulated that in all cases, between 660,000 tonnes lithium carbonate and 680,000 tonnes lithium carbonate can ultimately be recovered."
Multiple decades worth, we might just need some more bores down the track.
