This one is further to @redboomer and the HPQ question

Here's a link to our PFS webinar from a few years ago. Not a bad listen for starters for anyone that hasn't listened to it but from the 28 minute mark there is some good Q&A and one question is about HPQ which has some good info. Some of the other Questions and answers are really interesting for anyone still researching FYI. Link to PFS webinar
HPQ is one of a couple of other revenue opportunities we will hopefully build into our project other than HPA.

I think the initial intention was to do further work on the byproduct opportunities and include in the DFS however we left them out of the DFS. So obviously, they will be in addition to the DFS numbers.

I enquired about why these other byproduct opportunities weren't included in the DFS and the answer was they are still very much seen as opportuities that will add to our project however given some other opportunities that were beginning to come to light behind the scenes at the time they chose to put all resources solely into the core part of the project being HPA. The idea is that once we finalise the JV, and progress to the FID the JV venture will then explore the HPQ opportunity further etc.
On top of that, just as the DFS was released this year COVID hit and we cut costs and there was a decision to focus cash to the HPA side of things and protect shareholder capital as we were looking potentially at COVID hanging around for longer than it did in certain parts of the world like WA. As we know Roly turned off his salary for a number of months over this period.

Definitely worth as listen from the 28m mark.
