CUU own 25% Schaft Creek: proven/probable min. reserves/940.8m tonnes = 0.27% copper, 0.19 g/t gold, 0.018% moly and 1.72 g/t silver containing: 5.6b lbs copper, 5.8m ounces gold, 363.5m lbs moly and 51.7m ounces silver; (Recoverable CuEq 0.46%)
I found this report completed by Mira to be quite interesting in light that they will be doing a comparable study with our 2011/12 Aerial Mags and the other info in our geology database (Titan, drills, etc) and likely create a 3D images our our not so little district.
This formal correlation between the new, far reaching magnetics and the existing highly detailed database of the Schaft deposits (Paramount + Liard) complete with block models etc etc will be invaluable.
I dont know if everything done in this report will be repeated on our District but you can get an idea of how useful it will be to targeting the next follow up work and drilling.
(Coincidence that Xstrata owns 10.72% of Liard and partners with TCK and is looking for copper? http://agoracom.com/ir/CopperFoxMetals/forums/discussion/topics/530293-xstrata-copper-down/messages/1677248)
The title of the report speaks volumes, my bold:
"Discovery from 3D Visualization and Quantitative Modelling"

ABSTRACT The Noranda mining camp is one of the richest and oldest discovered base metal mining camps in the Abitibi Greenstone Belt. The area is undergoing a period of renewed exploration by Xstrata Copper with the purpose of finding new ore through the application of
new exploration technologies. One of the key tools in the application of new technologies is the use of a 3D-GIS system. A massive compilation program of the entire Noranda Camp was undertaken which included assembling all of the historical and current geology, geochemistry, geophysics, and drillhole databases within a single common software platform. A 3D “Common Earth Model”
of the Noranda camp was constructed which involved the importing of multi-disciplinary datasets and the propagation of the data throughout the model. The 3D platform aided in the understanding of the data and defining relationships between the various datasets. A series of well-defined visual and quantitative queries were developed to highlight prospective target areas based on conceptual ore deposit models. The West Ansil deposit is a base metal discovery made by Xstrata Copper and joint venture partner Alexis Minerals, located 14 km north of the Horne smelter in Rouyn-Noranda. The discovery is credited to the use of Gocad software where common earth modelling concepts and 3D-GIS tools were used.
The target was defined by a series of quantitative (proximity and property) queries developed from geological conceptual models. The discovery hole assayed an impressive 3.57% Cu over a core length of 52.7 metres, representing the first major base metal discovery in the Central Camp in the last 25 years. New discoveries are possible in mature mining camps thanks to the application of new technologies such as 3D-GIS systems. Quality exploration targets are best developed using all the available data in a common software platform from which multi-disciplinary datasets can be viewed and queried in a 3D environment.
