Glencore International is fully invested in Trevali's coming Peruvian production and mines, so you can bet that they will make the decisions for the management of Trevali step by step and more and more in their own interests.
Besides of that Trevali has to face challenges with its Canadian deposit. Don't forget they have to dig deeper. Why? Probably the high grade zones are covered by low grade zones. So that will increase the costs of mining to get access to the high grade zones.
Just my opinion.
