I don't know about corporate activity. Maybe but I doubt it.
The one thing that seperates KZL from the other zinc players is that besides the zinc/lead, they are sitting on a world class copper/gold resource that is waiting to be found. $15M is being spent to find it. It will be worth a dollar to the share price. (that's not according to me but to Macquarie RE).
That's probably why they are buying.
