On the hunt for copper, with three advanced stage porphyry projects
Experienced management with record of discovery and company value-building
Copper market undersupplied, with demand rising
What it does:
Vancouver-based Dunnedin Ventures Inc (CVE:DVI) is developing wholly-owned copper porphyry projects in British Columbia and Arizona along with the Kahuna diamond project in Nunavut - the most northerly territory in Canada.
Dunnedin is part of the Discovery Group of companies led by John Robins, one of the most successful mining entrepreneurs in Canada.
Its assets are the Trapper porphyry project in the northern Golden Triangle region of British Columbia, the MPD project in south-central British Columbia, and the Mohave copper-molybdenum-silver porphyry project in Arizona, USA.
All three projects have been previously drilled and are believed to overlie copper porphyry systems.
For those not familiar with the term, porphyry deposits are very large and much sought-after underground systems that typically contain copper and other metals. They can be several thousand feet in diameter.
Trapper is a 38 sq km land package, which has a 'textbook' copper/gold porphyry signature. Mapping and sampling is planned for this summer.
Mohave is a 10 sq km land package in Yavapai County, Arizona, 33km east of Freeport McMoran's Bagdad copper mine, with which it is geologically and structurally similar. Dunnedin says the project offers immediate exploration upside.
Dunnedin has benefitted from previous operator Bluestone and its comprehensive suite of high-quality exploration data. In 2011, Bluestone drilled 11 holes and reported anomalous mineralization over significant intervals in all.
Meanwhile, the firm's Kahuna project hosts a high-grade, near surface inferred resource of 4 million tonnes diamonds at 1.01 carats per tonne, 4 million carats of macrodiamonds (plus 0.85 mm) and numerous kimberlite targets and Dunnedin is working to define and prioritize drill targets. The resource is open along strike and depth
How it is doing:
The recent focus has been the group's MPD copper-gold porphyry project near Princeton, BC where newsflow has been particularly encouraging.
MPD covers a 78.5 sq km land package and despite being drilled by several operators over several decades, has never been explored as a single project with modern methods.
Ahead of a drill program planned to kick off in September this year, the company resampled two historic trenches in the Man area at the project and explored a broader, 25 sq km area that encompasses the historic Man, Prime and Dillard prospects, and results have prompted the firm to say the project could host a major discovery.
At the Dillard prospect, high copper and gold values were found, including 0.80% copper with 0.32 g/t gold, while at Prime, 0.49% copper with 0.26 grams per ton (g/t) gold over 2 metres was found. New copper-gold targets were identified 550 metres southeast of Man, in an area not yet drill tested.
Dunnedin has asked regulators for an exploration permit for up to 18 drill pads and up to 10 mechanical trenching sites in 2019 and 2020 at the project.
In May, when the group closed the acquisition of the Mohave copper-moly-silver project in Arizona, it said work there this year would evaluate historically defined targets, coincident geophysical/geochemical signatures and in particular, numerous anomalies not yet tested by previous drilling.
Potential inflexion points
- Drilling start at MPD project in BC
- Results from that project and exploration at Mohave
- Trapper project update
What the CEO says:
Claudia Tornquist, Dunedin's CEO said in an August update: "We are looking forward to the imminent start of our drill program and are especially excited that our first soil sampling program has already recognized new targets for follow-up in areas of the property not yet drilled by previous explorers."
