A new analysis has yielded positive results for Dunnedin Ventures[2]’ Nunavut-based Kahuna Diamond Project[3]. CF Mineral Research has found 338 micro-diamonds in its assessment of nearly 400 kg (881 lb) of kimberlitic material recovered from the project by rotary air-blast drilling.
The drilling was conducted on both new areas and extensions to established parts of the project, with the diamonds originating from 127.24 kg (280 lb) of the extension. All 338 are larger than 0.106 mm (0.004 in.), with four exceeding 0.85 mm (0.03 in.)
“The number and quality of larger diamonds in this initial sample are very encouraging,” said Chris Taylor, Dunnedin’s CEO. “Considering 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.”
More tests are also ongoing, including drill testing (expected to conclude later this month) and electromagnetic surveys of high-priority targets.
