Cadillac Ventures Inc. ("Cadillac" or the "Company") is pleased to announce the results of the Scoping Level Flotation Test work on copper-nickel-PGM ore from the K1-1 deposit, Thierry Project, Northwestern Ontario. In December 2012, Cadillac collected a 30-35kg Mini Bulk Sample from within the K1-1 Pit area, and a 30-35kg Mini Bulk Sample from outside the K1-1 pit.
A fulsome description of the sampling protocol and test work done is detailed below. The results can be summarized as follows.
Metal Liberation
Copper liberation was excellent, with copper sulphides, occurring mainly as chalcopyrite, 78% liberated in the pit area, and 75% liberated from the outside pit sample. Nickel sulphides, occurring mainly as pentlandite, were 53% liberated in the pit area, and 46% liberated outside the pit. It was also noted that there is a high nickel content resident in pyrrhotite and pyrite; the deliberate recovery of these by flotation will improve overall nickel recovery.
Test work grades better than Resource grades
The results of the Flotation Test work also demonstrate better grades than the grades of the existing 43-101 Resource at K1-1. The current K1-1 resource is an economic Whittle Pit inferred resource of 53.6 million tonnes at 0.38% Cu and 0.10% Ni. The in pit Mini Bulk Sample contained 0.52% Cu, 0.11% Ni, 0.068% Ni(S), 0.31 g/t PGM (Pt+Pd+Au), and 2.6 g/t Ag, the outside pit Mini Bulk Sample contained 0.46% Cu, 0.092% Ni, 0.058% Ni(S), 0.60 g/t PGM, and 2.0 g/t Ag.
Test work sample selection and preparation, processes
Representative samples for K1-1 ore, in pit and outside the pit, were determined by P & E Mining Consultants Inc., the designers of the economic Whittle Pit in place at K1-1. The identified core intercepts were identified in the field and the core was quarter sawn, bagged and tagged under the supervision of Dr. Howard Lahti P.Geo. The two mini-bulk samples were securely transported to the facilities of SGS Minerals Services in Lakefield, Ontario. The test work completed by SGS consisted of sample preparation, mineralogy characterization and flotation testing. A total of twenty flotation tests and two locked cycle tests were performed on the two Mini Bulk Samples.
Technical information in this press release has been reviewed and approved by Brian H. Newton P.Geo, of Billiken Management Services Inc. and a "qualified person" pursuant to the guidelines of National Instrument 43-101.
About Cadillac
Cadillac is a development-focused copper company currently advancing its 100% owned Thierry Property, near Pickle Lake, Ontario. The Thierry Property consists of the past producing Thierry Mine and hosts two NI 43-101 compliant resources: Thierry Mine and K1-1.
In addition, Cadillac also holds a 51% interest in the Burnt Hill Project, a historic tungsten/tin mine taken to test production by Mr. Norman Brewster P.Geo for Canadian International Paper during the early 1980's. Cadillac looks forward to resuming the development of this project.
