Dunnedin recovers 338 diamonds from first kimberlite drilled at Kahuna Project in 2018

11 July 2018

Dunnedin Ventures Inc. today provides new diamond results from its 100% owned Kahuna Diamond Project in Nunavut. As noted in its May 10, 2018 news release, new targets as well as hidden extensions to historical discoveries were tested using rotary air-blast (‘RAB’) drilling in the winter program. Nearly 400 kilograms of kimberlitic RAB material recovered from these targets was shipped to CF Mineral Research Ltd. (‘CFM’, Kelowna, British Columbia) for microdiamond recovery.
Results for 127.74 kilograms from the newly-identified extension of diamond-bearing kimberlite 07KD-24 include 338 diamonds larger than the 0.106 mm sieve size, including four commercial-sized diamonds larger than 0.85 mm. The five largest diamonds shown in Figure 1 include clear and colourless variants of octahedra totaling 0.072 carats. 
Chris Taylor, CEO of Dunnedin commented, “We are very pleased that our DIM-based exploration protocols have discovered the concealed extension to a potentially high-grade diamond source with high-quality diamonds. The number and quality of larger diamonds in this initial sample are very encouraging. Considering that RAB drilling is a rapid first stage exploration tool but can generate more diamond breakage than other drill methods, we  are very excited with this result and intend to follow-up with core drilling in our winter 2019 program to obtain more representative geological, grade and diamond data.”
