at last some news from wrn. i don't think this would explain why the stock has been so strong, but it looks like the casino property has the potential to become larger:

Western Copper Corporation ("Western Copper" or the "Company") (TSX:WRN - News) is pleased to announce that preliminary results from a Quantec Titan 24 deep penetration geophysical survey ("Quantec Survey") at its wholly owned Casino Project, located in the Yukon, have identified several zones of potential mineralization outside of the historical mineralization limits

Complete assays have been received for only one hole, CAS-014, drilled on the edge of one of the potential mineralized zones 500 meters outside of the historical mineralization limit (see attached figures). These assays indicate the existence of copper, gold and molybdenum mineralization, but at below ore grades.

Dale Corman, President & CEO said "We are very encouraged by the results of the Quantec Survey and initial drilling. The recent drill hole, CAS-014, confirms copper mineralization outside of the currently proposed pit and suggests there is a great potential to expand the Casino resource. We've now completed just under 6,000 meters of drilling in 21 holes, and will include these in an updated resource calculation when assays become available."
