RE: subprime messI believe the latest pull back is a combination of things.
1./ The entire PM market is down.
2./ Sprott and the other mutual funds will have had redemptions in the past little while and will have had to sell some shares to cover.
(I doubt very much that sprott has been caught in the subprime mess directly as they have been warning about the problem for years.)
3./ Minco is close to production (2008). There is usually a period when a stock transitions from an explorco to a producer where the traders loose interest (No excitement) and the investors are not on board yet (No income).
Minco in my oppinion is an extreme bargain here for patient investors.
