"Dear Clients,

Speculation is growing within the base and precious metal mining sector that merger and acquisition (M&A) activity will accelerate soon. Major produces like Goldcorp, Newmont, Barrick, and other operating companies continue to deplete their reserves and thus, are desperately looking for new sources of supply. Given the high capital cost and risk associated with exploration in an unproven area, it is more prudent to acquire mineral resources through an acquisition."
