The movement of the Goal Post regarding the Cauchari-Olaroz start of production only depends on what slice of the time frame you are using as a reference point.  If you are looking back in 2020 prior to March of that year then "early 2021" is the setting for the Goal Post.  Later in 2020 the Goal Post was moved to 1st Quarter of 2022 and now it has been moved again to 2nd Quarter of 2022.  A short description of the Goal Post for Production might simply be:  "In Flux"

Battery Industry on 19 August 2020 published an early picture of that "Flux" as noted below:

"Caucharí-Olaroz was slated to begin operations in early 2021, with production ramping up to 15,250 tonnes and 36,000 tonnes next year and in 2022, respectively.

The mine would achieve full production before the end of 2022, continuing to generate 40,000 tonnes per year from 2023 to 2060.

The projections were made before covid-19 hit the world economy. The company is now reviewing the impacts of the project’s suspensions on the timeline and budget. It said it would provide an update once those assessments had been completed."

And the "Flux" goes on.... and on... an on???   Hopefully, not.  Time to stop the "Flux"!!!
