The fresh new 2008 pre-feasibility study as well as included the initial NI 43-101 nutrient put aside guess into the Casino endeavor. The latest put aside imagine is based on pit framework and the exploit creation plan developed in the fresh new pre-feasibility investigation which can be said as the a mill ore reserve and you will heap leach set aside. The new stack leach reserve tonnage contour is actually high and also the silver degree is gloomier than one claimed regarding the funding estimate.
