doing a dry run

I gave NG a quick email yesterday regarding when production will restart.And will they have enough money to get restarted and into cash flow positive from trial mining, and about the rumors of others having a sniff around.
Got this reply
Restart is pending PHB,s mining plan, which is not a trial plan- its a full blown 4-5 year plan, sure it will start off in pilot fashion.
We are running through a dry run to see haulage and iron out kinks april 1-3 on site.
2 Yes absolutely not expensive to start at all
3 cant comment but plenty of people kicking tyres at the moment but i ant selling shares i can tell you.
