Dunnedin Ventures begins 2018 exploration program at Kahuna project in Nunavut

Published 29 March 2018

Dunnedin Ventures has commencement of its 2018 exploration program at its 100% owned Kahuna project, Nunavut, Canada.

Drill crews and equipment have been mobilized and preparations are under way to commence drilling of high–priority kimberlite targets at its 100% owned Kahuna project, Nunavut.  Drilling is expected to begin near the end of March and will continue through April as conditions permit.

A total of 17 high-priority targets have been identified for drill testing in the winter of 2018.  Most targets are pipe-like geophysical signatures associated with diamond indicator mineral chemistry occurring down-ice. In addition, drilling will investigate untested “blows”, or potentially wide sections along known high-grade diamond bearing kimberlite dikes. In order to ground-truth and delineate the drill targets, ground geophysical surveying using magnetic and OhmMapper electric-resistivity methods are currently being undertaken.

Chris Taylor, Dunnedin’s CEO stated, “We have observed excellent indicator mineral chemistry that is associated with diamonds at producing mines in till samples collected down-ice from our new drill targets.  In many locations the known diamond-bearing kimberlite dikes are unlikely to be the source of this chemistry, and the potential to identify new diamond-bearing kimberlites is high in these areas.”

Claudia Tornquist, Dunnedin’s President said, “This drill program is the culmination of three years of field work and the analysis of an extensive historic data set. We are fortunate to count Dr. Charles (Chuck) Fipke as our advisor whose expertise in prioritizing the most prospective drill targets is second to none. Our world-class exploration team benefits from many years of experience in Nunavut, and I am confident we have all the pieces in place to make this drill program a success.”

The 2018 winter drill targets occur in six priority clusters on the Kahuna Property and are presented as Figure 1a and 1b below.  The Company’s extensive historic geophysical database was used to model target areas three dimensionally and several targets demonstrate significant depth extent below 200 metres.  An example of geophysical compilation and modelling on high priority target KH009-01 is provided.

Dunnedin will utilize a Rotary Air Blast (“RAB”) rig to economically test the maximum number of targets during this maiden drill program.  The drilling is expected to reach depths of 50 to 75 metres, with the goal of collecting up to 250 kilograms of material from each new kimberlite. The material will be analyzed for microdiamond content and results are expected in late Q2 2018. Kimberlites that prove to be significantly diamondiferous will be further tested on future programs to determine size and to obtain mini-bulk samples. In addition, the Company continues to complete indicator mineral recovery, analysis and ranking from a remaining 733 priority till samples collected on the Kahuna property in 2017. Results will further delineate the six priority areas on the property.
