They will need it, in October 2012 RGLD raised $472.5 million in a private placement that will be used for royalty deals. 

Royal Gold intends to use the net proceeds of this offering for the acquisition of additional royalty or similar interests and general corporate purposes

This was during the period RGLD started to negotiate with Victoria Gold. With the SLW deal in place, there's easy to understand why they raised so much money. I just love this, FINALLY the streamers has to pay big money, delvelopers and operators will be the winners going forward.
