Dunnedin Ventures

Targeting Diamondiferous Kimberlite Pipes with Ekati Legend Dr. Chuck Fipke

This profile is part of a paid investor education campaign.*


Dunnedin Ventures Inc. (TSXV:DVI) is a Vancouver-based company whose primary asset is the 100% owned, advanced-stage Kahuna Diamond Project in Nunavut which hosts a high-grade, near surface inferred diamond resource and numerous kimberlite pipe targets.  The Company holds diamond interest on 1,664 km2 of mineral tenure located 26 kilometers northeast of Rankin Inlet and adjacent to Agnico Eagle’s Meliadine gold mine.

Drilling Kimberlite Pipe Targets

The main catalyst for Dunnedin through 2018 will be the Company’s first drill program, slated to begin in March 2018. The Company will drill test 10 to15 highly prospective kimberlite targets selected by the technical staff under the guidance of Dr. Charles (Chuck) Fipke, Dunnedin’s technical advisor.

  • Q1 2018 – Priority till processing, target definition, camp construction, full mobilization
  • Q2 2018 – Drilling of kimberlite pipe targets and/or resource drilling
  • Q3 2018 – Diamond recovery from drill program, follow-up drilling and exploration
  • Q4 2018 – Diamond recovery from drill program, priority till processing and target generation

To define and prioritize kimberlite pipe targets, Dunnedin has evaluated an extensive historic data set and recovered diamonds from several kimberlites and studied indicator minerals till samples collected over three field seasons. The Company has used the same till sampling and mineral screening protocols employed during Dr. Fipke’s discovery of Canada’s first diamond mine at Ekati, NWT, but improved by over 20 years of additional diamond data and experience.

The focus of Fipke’s process is to identify circular geophysical pipe-like features that have potential for significant size and value.  Dunnedin has a high degree of confidence that drilling will hit diamondiferous kimberlite based on the presence of diamond indicator minerals (DIM’s) occurring immediately down ice (red dots in image below), but not up ice (grey dots) of target (see image below).

Expanding an Existing Diamond Resource

The Kahuna Diamond Project has an Inferred Resource Estimate of 3,987,000 tonnes at an average grade of 1.01 carats per tonne, totalling over 4 million carats of diamond (+0.85 mm).

Kahuna Inferred Resource Estimate*


The maiden mineral resource estimate for the Kahuna Diamond Project also reported a Target for Further Exploration (“TFFE”) of additional 4,090,000 to 15,880,000 carats of diamonds.

Target For Further Exploration (TFFE)*

* “Technical Report and Maiden Mineral Resource Estimate for the Kahuna Diamond Project, Nunavut, Canada” prepared by APEX Geoscience Ltd., Kristopher J. Raffle, B.Sc., P. Geo. and Andrew J. Turner, B.Sc., P. Geol. March 11, 2015. Note that bulk sampling has established that Kahuna has a recovered grade of 1.04 cpt and Notch has a recovered grade of 0.90 cpt for an average grade of 1.10 cpt (at a +0.85 mm lower cut-off). Figures may not sum due to rounding. Decimal figures do not indicate added level of precision. Cpt = carats-per-tonne .                         The reader is cautioned that Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability and might never be converted into Reserves. Also note that the potential quantity and grade of any TFFE is conceptual in nature, there is insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the target being delineated as a Mineral Resources or Mineral Reserves.

Bulk sampling and historic drilling on the three main kimberlites, Kahuna, Notch and PST, has returned significant macrodiamond counts. The largest diamond recovered from the property to date is a 5.43 carat stone from the Kahuna dike which was a piece of a larger diamond that had been broke during the sample preparation process and was reconstructed as having an original size of 13.42 carats.  The majority of diamonds are reported as clear and colourless to white, with a significant population of octahedral stones, however coloured stones have also been reported.

Trapper Project

Dunnedin’s wholly-owned Trapper Project is a 40 km2 land package adjacent to Brixton Metal’s (TSXV: BBB) Thorn property in northern British Columbia. Trapper hosts a gold-rich copper porphyry complex which includes a circular mineralized zone, known as the Ring Zone, over 6 kilometers in diameter displaying sulphide mineralization with over 10 kilometers of strike surrounding the porphyry center.

Trapper Project Highlights

  • Gold rich porphyry system with visible gold
  • 8,581 metres drilled in 42 diamond drill holes
  • 6 of 8 mineralized zones tested
  • 3 zones drilled with gold-rich polymetallic mineralization
  • Strike length of 2.3 kilometres, open to east and west
  • Potentially open pit and underground mineable targets
