I've made a lot of money follwoing the advice of Rick Rule generally
Here's a recent interview where he comments for a few minutes on the EDV/TGZ Merger

"This is a case where 5+1 = 7"
"G&A reductions of $ 60-$70M. It's like a small mine that never depletes"
"Lundins proved that merging lowers your cost of capital"
"enthusiastic about Africa"
" I like this merger from every angle"
