Carlos Slim's Minera Frisco Buys More Gold & Silver in the Ground from Aurico

Carlos Slim's Precious Metal Mining company, Minera Frisco, announced the purchase of Aurico's Ocampo mine and exploration assets in Chihuahua state Mexico for $750m.
Ocampo was the old Gammon Gold mine.

Aurico's stock jumped 20% higher, they will focus on Young Davidson in Canada and the former Capital Gold assets in Mexico.

So why did the world's richest man want a mine which has always struggled to fulfil its promise under Gammon and Aurico?
