Dart Mining’s (ASX: DTM) principal project is Unicorn – a molybdenum-copper-silver porphyry deposit with strong geological similarities to the Henderson molybdenum mine in Colorado, USA. The company also has two gold projects including Mountain View and Fairley’s disseminated gold prospect.
The Gilmore suture - a proven host of substantial porphyry mines including North Parkes, Cadia and Ridgeway in NSW and the Benambra VMS deposit in Victoria - crosses into Dart Mining’s 2500 square kilometres of tenements.
Dart Mining unveils maiden 100mt molybdenum resource at Unicorn in Victoria
Dart Mining (ASX:DTM) has reported a higher than expected maiden JORC resource of 105 million tonnes Indicated and Inferred Resource at 0.07% Molybdenum equivalent for the Unicorn Deposit near Corryong in north east Victoria.
However, based on the drilling results to date, and infill drilling planned these tonnages should increase and allow an Indicated Resource to be estimated to 450 metres depth.
The initial Resource estimated for the Unicorn deposit is interpreted to represent only the upper limits of a very large intrusive porphyry system which has already shown multiple stacked high grade molybdenum zones.
Unicorn is comparable to a style of deposit that typically shows economic mineralisation extending well below 1000m depth.
AMC Consultants finalised the maiden resource estimate which included an initial 29 million tonne Indicated Resource at 0.09% molybdenum equivalent from surface to a depth of 250 metres at a very low strip ratio.
Interestingly, the resource is open at depth with power and water in close proximity and established logistics chain to market.
Limited exploration drilling has extended outside the porphyry contacts to date, however surface geochemistry and drilling has already highlighted significant Mo, Cu and Ag grades in the mineralised wall rocks and southern breccia zone.
This mineralised zone has not been included in the indicated or inferred resource as yet.
Further drilling will aim to define the extent of the mineralisation surrounding the main porphyry with the intent to include this material in future updates to the Resource.
A series of deeper diamond drill holes are being planned to test the system below 450 metres in 2012.
