Dunnedin Reports 0.80% and 0.76% Copper in Grab
Samples and Identifies New Copper-Gold Soil Anomalies
at MPD Porphyry Project, Southern British Columbia
Vancouver, British Columbia--(Newsfile Corp. - August 29, 2019) - Dunnedin Ventures Inc. (TSXV: DVI) (the "Company" or
"Dunnedin") today announced
further sampling and prospecting results from the 2019 exploration program at its 100% owned,
road-accessible MPD Copper-Gold Porphyry Project ("MPD") in Southern Central British Columbia.
In preparation for upcoming drilling, the Company completed a mapping, prospecting and sampling program. The Company
recently reported significant copper and gold results from trenches at the "Man" area including 0.89% copper over 46.0 metres
(see news release dated August 22, 2019) and the remainder of this work is reported herein. Dunnedin is very encouraged by
these new results, which have generated new target areas and helped focus our upcoming drill program.
Select assay results from prospecting work at MPD are provided in Table 1. Highlights include:
High copper and gold values at Dillard, including 0.80% copper with 0.32 g/t gold, and 0.76% copper with 0.24
g/t gold in grab samples
Copper-gold and gold-silver mineralization at Prime, including 0.49% copper with 0.26 g/t gold over 2 metres
and; 1.03 g/t gold with 9.40 g/t silver in grab samples
Significant copper mineralization defined at Belcarra with 0.19% copper and 0.08 g/t gold trenched over 22.5
metres, 800 metres northwest of Man.
2019 soil sample results have identified
new copper-gold targets 550 metres southeast of Man
, in an area not yet
tested by drilling, but comparable to soil anomalies over the known mineralization at the Man target
Mineralization occurring in both rock and soil samples over a broad area at MPD
validates the potential for a
significant copper-gold porphyry system
and the opportunity for new discoveries on the property
Claudia Tornquist, President and CEO of Dunnedin said, "Results from surface sampling continue to identify significant surface
mineralization across the MPD property, highlighting the opportunity for a major discovery within this under-explored,
consolidated land package. 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."
MPD Prospecting and Sampling
As part of preparatory work for the 2019 drill program, Dunnedin field staff resampled two historic trenches in the Man area (see
news release dated August 22, 2019) and explored a broader, 25 square kilometre area that encompasses the historic Man,
Prime and Dillard prospects. Grab and trench samples were collected from outcrops and trenches encountered during
prospecting-mapping traverses (see Figure 1). The Company collected 48 prospecting rock samples, either as grab samples
from outcrop, or as 1 to 2 metres chip samples in trenches. Samples collected in all three target areas (Man, Prime Dillard)
returned significant copper mineralization with associated gold and silver (see Table 1).

A series of six grab samples from copper-bearing boulders in the Dillard area are described as volcanic rocks hosting irregular
quartz-carbonate veining with disseminations and stringers of chalcopyrite, pyrite and minor malachite.
Similarly, mineralized
rocks were also noted in the Prime area where a chip and grab sample contained significant gold and silver. Historic mapping in
both areas reference Nicola Group volcano-sedimentary rocks being intruded by porphyritic syenite-monzodiorite dykes and
stocks.
A steep slope referred to as the Belcarra trench was sampled one kilometre northwest of the Man trenches. Copper at Belcarra
occurs as malachite on fracture/contact surfaces, or as chalcopyrite disseminations over a 22.5 metre section of exposed and
altered bedrock. Mineralized host rocks at Belcarra look very similar to the variably-altered porphyritic intrusive and volcanic
assemblage observed in the copper-bearing Man trenches.
MPD Soil Geochemical Survey
The Company has identified significant copper and gold-in-soil anomalies on the SE Man soil grid in an area south east of Man
and not yet tested by drilling.
Historic soil geochemical surveys at MPD were restricted to local grids, often overlapping and missing multielement data or
specific metal analyses. To compare the efficacy of historic soil sampling, the Company collected 200 soil samples over an 800
by 1000 metre grid area (SE Man grid) located southeast of the historic copper-in-soil anomaly defined at Man.
Samples of "B" horizon subsoil were collected at 50 metre intervals along sample lines spaced 100 metres apart. Historic grids
in the area did not test for trace elements or precious metals. New assay results from the 2019 soil survey highlight gold values
immediately south of the Man trenches and pronounced copper, gold and silver anomalies central to the grid and 550 metres
south of the Man trenches. These anomalies reflect the metallic suite targeted in porphyritic host rocks and are analogous to
known mineralization and the copper-in-soil anomaly present at Man. (see Figure 2).

Anomalous copper values up to 201 ppm and gold values up to 136 ppb overlap in the north central portion of soil survey, with
some offsets either due to peripheral zoning or depth of overburden. Table 2 shows value ranges and anomalous thresholds for
copper-gold-silver on the 2019 SE Man soil geochemical survey.

The MPD Project's Nicola Belt geology has many similar characteristics to nearby alkalic porphyry systems at the Copper
Mountain Mine to the south, and New Gold's New Afton Mine to the north. Past exploration has identified numerous copper
showings over a large, 10 square kilometre area. Copper and gold mineralization extend from surface, with earlier drilling on the
property rarely testing below 200 metres vertical depth. Several historic holes that exceeded 200 metres indicate the potential
for porphyry-type mineralization of significant depth and size.
MPD 2019 Permitting
Dunnedin has applied for a multi-year area-based Exploration Permit with the British Columbia Ministry of Energy, Mines and
Petroleum Resources requesting authorizations allowing up to 18 drill pads and up to 10 mechanical trenching sites in 2019 and
2020.
This application is in the final stages of the review process by regulators
and drilling will commence upon receipt of
the permit, which the Company expects in September
.
QA/QC
All rock and soil samples were sent to ALS Canada Ltd. (ALS) in North Vancouver, BC for preparation and analysis. ALS meets
all requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015 for analytical procedures. Rock samples
were analyzed using ALS's Fire Assay Fusion method (Au-AA24) with an AA finish for gold; and by a 33-element four acid
digest ICP-AES analysis (ME-ICP61) with additional analysis for Ore Grade Elements (ME-OG62) and Ore Grade Cu (Cu-
OG62). Soil samples were analyzed using ALS's AuME-ST43 Super Trace Au + Multi Element package. Results were reported
in parts per million (ppm) and converted to percent (%), grams per tonne (g/t) or parts per billion (ppb) when applicable. QA/QC
includes field duplicates and field standards. Laboratory QA/QC includes standards, duplicates, re-assays, and blanks inserted
by ALS. All QA/QC results were within expectations.
