I figured part of the rise in SLW and possibly beyond is that now SLW might have another supplier of silver from the former Western Silver operations, which has "one of the world’s largest open pit silver deposits at Peñasquito, Mexico, in an area with excellent infrastructure and low political risk."
Initially I didn't like the large premium that GG paid to acquire Glamis, but they are both low producers and I think that the silver aspect, which was not emphasized in the press release, contains an indirect bonus to GG and SLW. Just a thought.
But it's always good to take profits, if you have good alternative investments.
