The second, 1.30 tonne sample of Notch returned 49 commercial-sized stones (+0.85 mm) totalling 1.29 carats, for a sample grade of 0.99 carats per tonne. The largest recovered diamond was a 0.23 carat clear and colourless octahedral stone. Results are provided in the table below along with an image of the two largest stones.

We continue to be impressed with the quality of diamonds recovered from our kimberlites,” said Chris Taylor, CEO of Dunnedin, “Till samples, drilling and geophysics all suggest Notch may have up to double the 2.6 kilometre strike length that was used to calculate its published potential for 2 – 5 million carats of commercial sized diamonds as reported in our NI 43-101 compliant Inferred Resource and Target for Further Exploration. Notch therefore presents an attractive target with significant potential for further resource expansion and bulk sampling.”
Most of the Notch diamonds recovered by Dunnedin are clear and colourless variants of octahedra. On January 26, 2015, Dunnedin published a NI 43-101 compliant Inferred Resource for Notch prepared by APEX Geoscience Ltd. (“APEX”) with the following highlights:
Dunnedin followed with publication of a Target for Further Exploration (“TFFE”) that provides additional potential tonnages and contained carats that are not yet included in the Notch Resource, also prepared by APEX (see Dunnedin news release of March 31, 2015) of an additional 1.10 to 4.05 million carats based on a range of possible grades and depth extents. Note that the TFFE conservatively does not include any consideration of potential additional strike extent.
