RE:RE:RE:RE:RE:Trading HaltOf course grade is a factor for open pit. If the strip ratio is low at say 1:1 than the grade is doable when considering the cost of oil to run the mine as there is no electricity. If the strip ratio is say 10:1 than the grade may not work. They need to provide the waste to ore ratio. Gold was at $400 when it closed but oil was also at $20. the strip ratio is important as costs will be higher starting at the bottom of the pit. Also they need to disclose how deep they modeled the pit. Is the resource down to 450 meters?? These are facts that need to be provided - is this why Silvercorp decided to reduce their ownership in the company? Reading rbr release I don't see strip ratio or depth of constrained pit
