SadHow did this company raise so much money go so many years and no one thought of calcite and acid reacting as an issue. A simple Google search shows that acid reacting with calcite causes fizzing. Take that info and add a high amounts of acid and calcite and you get major fizzing aka gas bubbles. I have been in this stock for 10 years and I have never been more upset in my life with an investment. I have sold a bunch of shares over the last few months but still hold alot. The last few years have been painfully brutal now add in a share price that is dropping every other week makes it so much worse.Greenstone has invested huge money. Triple flag invested 75 mil to be paid back with copper sales.... Copper needs to be produced for these guys to get paid back... I wonder what they are thinking right now. I truly hope that this story turns positive soon. Money is being burned each month trying to get this mine running right. Judging by the share price these are not just your typical start up issues. We are going back to pre feasibility level prices. Sad
