Low environmental impact ....?21 Dec 2019 06:33
I notice willemite was detected in preliminary Met report. I did a bit of research on this and found this as a result…
“Willemite (zinc silicate) is the main zinc mineral in some carbonate-hosted ore deposits (e.g., Franklin, New Jersey; Vazante, Brazil; Beltana, South Australia; Kabwe, Zambia). Recent interest in these unconventional zinc deposits has increased because of high zinc grades that exceed 40 wt percent, relatively low environmental impact of ore processing owing to the lack of acid-generating sulfides in the waste, and advances in ore processing technologies”
So this is actually good news and augurs well for the finalized Met report as for this by product it appears to have low environmental impact…which is a huge plus
Any other research on dolomite and smithsonite being present would be most welcome…
