Dunnedin Ventures Inc. (TSXV:DVI) primary asset is the advanced-stage Kahuna Project in Nunavut which hosts a high grade, near surface inferred diamond resource and significant gold-in-tills. Dunnedin has an option agreement to earn a 100-percent interest in the project which is located within 42 kilometers northeast of Ranklin Inlet and the surrounding infrastructure of Agnico Eagle’s (TSX:AEM;NYSE:AEM) Meliadine gold mine. The company staked additional property in late 2016, doubling the size of the Kahuna Project to 120,000 hectares.
- Most recovered stones are clear and colorless variants of octahedra
- Historical recovery of large diamonds including a reconstructed 13.4 carat diamond
- Presence of diamond indicator minerals, shown by advisor Chuck Fipke’s research work, to be associated only with large diamonds
The Kahuna Project consists of more than 100 interpreted kimberlite pipe targets, half of which are currently being screened for down-ice diamond indicator mineral chemistry from till sampling. More than 200 kilometers of aggregate strike length of a kimberlite-intruded structural network exists on the property including 10 drill-proven diamond bearing kimberlite dikes with sample grades ranging from 0.66 to 6.5 carats (+0.85 mm) per tonne.
The Kahuna kimberlite is a large target with a maiden Inferred Resource of over 3 million tonnes, and potential for an additional 3.7 to 10.7 million tonnes at a range of depths.* Historical bulk sampling yielded 1.04 carats (+0.85 mm) per tonne, but audits to determine a final sample grade do not appear to have been completed by the past operator. A recent sample announced February 8, 2017 returned 2.35 carats per tonne. “The Company is strongly encouraged by the size and grade potential of this kimberlite, and we view bulk sampling to determine diamond value as a priority,” says Chris Taylor, Dunnedin’s CEO.
The Inferred Mineral Resource estimate was prepared by APEX Geoscience Ltd. on the Kahuna and Notch kimberlites based on data from the 2006 – 2008 bulk sampling and drill programs completed by the past operator. It comprises 4,018,000 carats of macrodiamonds at a 0.85 mm (+1 DTC sieve size) lower diamond cut-off, with an average grade of 1.01 carats per tonne (cpt), or 101 carats per hundred tonnes (cpht) derived from 3,987,000 tonnes of kimberlite resource.
In addition to Kahuna, PST and Notch, there are several dike and pipe targets on the property that have yet to be explored for diamond-bearing potential.
*Cautionary statement: Details of an Inferred Resource and Target for Further Exploration have been published for the Kahun kimberlite, both of which were completed by APEX Geoscience Ltd. And are available as a National Instrument 43-101 technical report filed on SEDAR (www.sedar.com) on March 12, 2015. Mineral Resources are not Mineral Reserve and do not have demonstrated economic viability. The potential quantity and grade of a Target for Further Exploration 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 resource.
Gold mineralization identified at Kahuna
The 2015 exploration program at Kahuna also led to the discovery of gold adjacent to the project’s diamond-bearing kimberlites. Gold was found through neutron activation analysis of heavy mineral concentrates in 65 percent of the till samples collected by Dunnedin in 2015. These gold results along with historical drill core have helped to define multiple gold targets across the property. Metasediment belts including those that host gold at Agnico Eagle’s Meliadine have been repeated through regional folding and on-strike extensions at Kahuna, where they also host gold.
Historical gold data on the property includes:
- Ninety-seven mineralized historical grab samples returning between 0.05 g/t and 2.52 g/t gold were collected across five metasediment and structural zones with approximately 190 kilometers of aggregate strike length.
- Historical drilling targeting kimberlite encountered visible gold returning 7.24 g/t gold over 0.68 meters along the strike extension of Agnico’s Aklak and Aquik Gold Zones of the adjacent Meliadine property, showing that gold mineralization is indeed also present at Kahuna.
Recently, exploration and development activity has increased in the area of the Kahuna and Meliadine projects. Agnico has extended their land position into areas of Inuit-owned subsurface rights adjacent to Dunnedin’s claim. NxGold Inc. (TSXV:NXN) has inked an earn-in deal totaling more than $35 million for a 70-percent interest in a 85 square kilometer land package adjacent to the Meliadine claims while raising $4.1 million for exploration in the area.
Dunnedin expects to begin a field work program in 2017 which will include drill testing to potentially grow the current diamond inferred resource base; completing a bulk sampling program to assemble a valuation parcel of approximately 1,000 carats of commercial-sized diamonds; and exploring newly defined high priority kimberlite targets.
On the gold side, Dunnedin will review a recently purchased data set containing additional historical exploration results from the project. The Company is currently analyzing gold-in-till results from this historical work, along with additional diamond exploration data, and plans to release more results as soon as they are available.
- Advanced-stage Kahuna diamond project with known diamond-bearing kimberlites open to expansion with limited drilling.
- Large-size diamond potential confirmed with recovery of 1+ carat stones including a reconstructed 13.4 carat diamond.
- Early-stage gold-in-till results.
- Located in close proximity to Rankin Inlet, Nunavut, Canada; tidewater at Hudson’s Bay; Agnico Eagle’s recently built Meliadine mine; and NxGold property.
- Trapper gold-copper project has been the subject of more than $4 million in exploration.
- 2-kilometer drill-defined gold system; porphyry complex with alteration signature of over 15 square kilometers.
- Spin out of gold and copper assets under review
Trapper Gold-Copper Porphyry
Dunndin Venture’s wholly-owned Trapper project is a 40-square kilometer 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 including 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 2.2 kilometres, open to east and west
- Porphyry associated deposit –zoned mineralization
- Potentially open pit and underground mineable targets
