NEW KIMBERLITE PIPE TARGETS WITH DIAMOND POTENTIAL IDENTIFIED AT KAHUNA
June 5, 2017 – Vancouver, BC, Canada. – Dunnedin Ventures Inc. (the "Company" or "Dunnedin") (TSX-
V: DVI) today reported the identification of new kimberlite pipe targets with down-ice till chemistry
matching known diamond-bearing kimberlite dikes at the Kahuna project. These are priority drill targets
for 2017 that the Company believes have strong diamond potential.

targets shown in insets. Magnetic total field geophysics shown. Results are from 208 of 1,111 samples
received to date.
The Company processed kimberlite from the highly diamondiferous Kahuna, PST and Notch kimberlite
dikes and also from the KEM dike, a barren body , to compare the indicator mineral signatures of
diamondiferous versus barren kimberlites. All three of the Kahuna, PST and Notch had certain indicator
mineral chemistries in common that were absent in the barren body. These diamond-associated mineral
chemistries have now been recovered from till samples down-ice from new kimberlite pipe targets in
several areas.
“The Kahuna project covers one of the largest, mostly under tested kimberlite pipe fields in Canada,” said
Chris Taylor, CEO of Dunnedin. “While we remai n positive on the potential of our diamond -bearing
kimberlite dikes such as Kahuna, Notch and PST, the opportunity to additionally benefit our shareholders
through a new discovery drives us to also test the pipes. With these new results in hand, we aim to make
2017 a year of discovery, diamond valuation and resource growth.”
Summary of Results
• Results received for 208 of 1,111 (19%) till samples collected in summer 2016, with results from
the remaining 903 samples expected to be received through June.
• To-date, up to seven potentially diamond-bearing kimberlite pipe targets have been identified with
associated DIM dispersions in down-ice tills. Targets will be ranked for follow up exploration and
drilling once all results are received. The total number of targets, and their relative strengths based
on DIM content, will be provided at that time.
• Field crews will be mobilized during June to begin field investigations of these and other targets
across the Kahuna project, with drilling expected to being this summer.
• The Kahuna project is notable for yielding DIM chemistry associated with large diamonds
recovered at producing diamond mines, including Ekati, which has been validated by recovery of
large diamonds (up to 13.42 carats) at Kahuna.
• Certain chemistries of the DIMs clinopyroxene, chromite, garnet and picroilmenite are observed
consistently within the diamond -bearing kimberlite dikes, and are also found down -ice from the
newly identified targets.
• The geophysical signature of historically drilled kimberlite pipes generally consists of negative in-
phase electromagnetic responses and variously high and low magnetic responses that are distinctive
from background geology. The newly identified kimberlite pipe targets are consistent with these
signatures, but require drilling to verify.

About Till Sampling for Diamond Exploration
Glacial till sampling is used extensively in the Canadian Arctic as a primary exploration tool leading to
most major diamond discoveries, the most famous example of which is Ekati , which was discovered by
Dunnedin’s advisor Dr. Charles Fipke.
Heavy mineral recovery from tills retrieves kimberlite indicator minerals (‘KIMs’) that were eroded from
kimberlites by glaciers and deposited “down -ice”. This creates a train of positive till samples that can be
tracked back to their original source.
Some KIMs have chemical signatures that indicate source within the diamond stability field in the lower
continental crust. These are referred to as Diamond Indicator Minerals, or DIMs. Certain DIM chemistries
are known to be characteristic of the occurrence of larger diamonds, based on data sets collected from
producing diamond mines. The Kahuna project’s diamond -bearing kimberlites contain these DIMs , and
have also yielded large diamonds.
Dunnedin’s till sampling program utilizes the same sampling and mineral ranking techniques as applied at
Ekati, which can predict the potential of kimberlites to host diamonds with a high degree of confidence .
The ranking employs proprietary mineral chemistry filters developed at CF Mineral Research Ltd. (“CFM”)
of Kelowna, British Columbia, under the direction of Dr. Fipke.
About the Kahuna Project
Kahuna is an advanced stage high grade diamond project located near Rankin Inlet, Nunavut. Dunnedin is
now recovering diamonds and indicator minerals from a series of kimberlite and till samples collected in
from two seasons of field work. An Inferred Resource released by Dunnedin showed over 4 million carats
of macrodiamonds (+0.85 mm) at a grade of 1.01 carats per tonne had been defined along the partial strike
length of the Kahuna and Notch kimberlite dikes through shallow drilling. The largest diamond recovered
was a 5.43 carat stone from the Kahuna dike which was a piece of a larger diamond that had been broken
during the sample preparation process and was reconstructed as having an original size of 13.4 2 carats.
Recent results include a 0.82 tonne sample of the PST kimberlite dike which returned 96 macrodiamonds
totalling 5.34 carats (+0.85 mm) and a 2.36 tonne sample of the Notch kimberlite which returned 89
macrodiamonds totalling 2.38 carats (+0.85 mm).
The Kahuna project is located adjacent to the development -stage Meliadine gold project of Agnico Eagle
Mines Ltd. Meliadine has approximately 14.5 million tonnes of Proven and Probable Reserves grading 7.32
g/t gold, containing 3.4 million ounces of gold as of December 31, 2015. There is an additional Indicated
Resource of 20.7 million tonnes grading 4.95 g/t gold containing 3.3 million ounces of gold, and an
additional Inferred Resource of 14.7 million tonnes grading 7.51 g/t gold containing 3.5 million ounces of
gold (source: www.agnicoeagle.com).
