Ann: Exceptionally High-Grade V-Zn-Pb Concentrate from Abenab, page-20

i think the why is there for all to see... if you go back through the announcements, they had already planned gravity testwork in Jan 2022:

As at July, gravity testwork was "well advanced", so not only had they kicked it off, it was what I would interpret as mostly complete?

Now, a further 6 months later they finally have completed and shared the test results.

So 12 months to execute a small gravity testwork program with spirals and gravity tables.. now extrapolate that to bringing a mine online Compare like-to-like to any of the quartz sand plays on ASX and how quick they move through bench piloting PFS DFS also using, you guessed it, spirals and tables!

I still think this stock is worth a swing trade though in my opinion, it moves +20-60% every now and then
