Thanks for info.. Took a look at the history and it's an interesting comparison and huge when added together:
GDR leases - Tubal Cain (33,278 ounces), Happy-Go-Lucky (14,000 ounces), Longfellow’s (10,000 ounces) and Eureka (2,669 ounces)
MCO leases - Morning Star (883,000 ounces), Loch Fyne (109,000 ounces), Comet (64,000 ounces), All Nations (132,000 ounces)
There's some serious dykes along that line to break open!
