One thing to keep in mind about the Savkino projections is that the first quarter is basically does not exist as the mine is shut down due to weather. If you figure the 2nd quarter is ramping up and getting going again it would make sense that they have the bulk of production in the 3rd and 4th quarters.
As far as Lamaque and San Juan they have missed projections every quarter with a myriad of excuses so time will tell.
