- A fragment (or xenolith) of well mineralized intrusive within barren granodiorite was observed in drill hole MX07-03; - Disseminated molybdenite has recently been observed in intrusive rocks at the 805 mine level, currently below the Z zone described previously; and, - Strong quartz stockwork with molybdenite in biotite hornfels has been observed adjacent to the Ethel zone (Drill Hole MX07-01).
