RE:Merger....Could be. If Falea will prove to be a jewel of the new company, than RGT shareholders are losing half of it. Since there are no more flagships left beside the Falea, cash will be burned for PFS and further for DFS.
Number of shares are irrelevant, especially since there will be reverse split 1:10 in Mega.
The recent events in Mali must taught RGT directors that political risk is not something entirely theoretical.
Mega has little cash, but almost nothing to spend on; instead, they have very interesting holdings. Toro - is late stage development compnay with large enough deposit, almost surely will be developed and Nexgen has very interesting prospect - Paterson Lake North (right next to Alpha - that found what is could be next World class reserve).
Would Mega wanted to sell these two it could have 40M in cash.
