Dunnedin Provides Update on Kimberlite Sample Processing
October 8, 2015 / TheNewswire / Vancouver, BC, Canada. - Dunnedin Ventures Inc. (the "Company" or "Dunnedin") (TSX-V: DVI) is pleased to announce that processing of the Company's first kimberlite sample from the 2015 summer field investigation program is approximately 50% complete. Roughly four tonnes of kimberlite were collected in the summer program (see news release of June 29, 2015). Diamond results for the first sample are expected by mid-November.
Processing is presently underway at CF Mineral Research Ltd. ("CF Minerals") of Kelowna, British Columbia. The dry weight of the first sample is 0.82 tonnes, and consists of in-place kimberlite hand-excavated by Dunnedin's field crews from the PST target. The PST kimberlite had a previously reported grade of 2.18 cpt (+0.85 mm) but lacked sufficient historical drill definition for inclusion in the 4 million carat Inferred Resource based on the Kahuna and Notch kimberlites that was released by Dunnedin earlier this year (see news release of January 26, 2015; average grade of 1.01 cpt (+0.85 mm) from 3.99 million tonnes of rock). The Company believes PST is of interest for additional resource definition due to its high diamond grade potential.
The sample is being treated through an autogenous milling-caustic fusion circuit that uniquely allows for recovery of both indicator minerals and diamonds from the same sample. Based on previous results, the sample is expected to produce diamonds that Dunnedin will characterize in order to guide future work. The indicator minerals will be ranked by chemistry using proprietary techniques at CF Minerals, and the results will be used to prioritize other targets across the property.
Additional samples from the Notch, Kahuna and other kimberlites will be processed once the first PST sample is complete.

About the Kahuna Project
Kahuna is an advanced stage high grade diamond project located near Rankin Inlet, Nunavut. Three main diamondiferous kimberlite dikes, Kahuna, PST and Notch, have been drilled and bulk sampled and returned grades of 0.85 to 2.18 carats per tonne. An Inferred Resource released by Dunnedin showed over 4 million carats of macrodiamonds (+0.85 mm) at a grade of 1.01 carats per tonne had been defined along the partial strike length of the Kahuna and Notch kimberlites through shallow drilling. The largest diamond recovered was a 5.43 carat stone from the Kahuna dike that had been broken during the sample preparation process and was reconstructed as having an original size of 13.42 carats. The dikes have comparable strike lengths, widths and grades to producing diamond mines and occur within a broad network of largely untested geophysical targets, overlain by dense diamond indicator mineral trains.
