Dundee Sustainable Technologies Inc. ("DSTI" or the "Corporation") (CSE:DST),
the developer and owner of proprietary technologies to serve the natural
resource sector with environmentally friendly procedures, is pleased to announce
sampling results from its nickel (Ni) laterite deposit in Guatemala and the
successful application of its patented proprietary extraction process.


The Corporation is pleased to announce nickel results up to 3.06 % Ni from
DSTI's 100% owned, Rio Negro property located in Guatemala. In May of 2014, DSTI
conducted a sampling campaign on the Rio Negro property; the purpose of the
field work was to confirm known mineralisation and the application of its
patented proprietary nickel extraction process.


A total of four (4) samples were taken from four (4) pits, averaging 10 metres
in depth, located 250 metres apart along a 1,000 metres North-South strike
length. The area consists of nickel bearing laterite mineralisation developed in
zones of shearing and faulting within large ultramafic units. Composite samples
of mineralised material were prepared and sent to DSTI's Thetford Mines facility
for analysis and returned the following values:




---------------------------------------------------------------------------
                        RN-119         RN-126         RN-144         RN-257
---------------------------------------------------------------------------
Ni                      1,55 %         1,81 %         3,06 %         0,68 %
---------------------------------------------------------------------------
Mg                      2,35 %         5,21 %         2,71 %         1,08 %
---------------------------------------------------------------------------
Fe                     26,67 %        18,43 %        21,20 %        39,76 %
---------------------------------------------------------------------------



The Corporation's patented proprietary process for nickel extraction from
laterites for the production of nickel sulfate was applied on the Rio Negro
samples and achieved a nickel extraction of 90%, at ambient pressure and
moderate temperature, over a short period of time. As opposed to conventional
pressure leaching, DSTI's proprietary process operates at atmospheric pressure
and ambient temperature with no limitation on magnesia (MgO) and silica (SiO2)
content, using diluted sulfuric acid and low energy consumption. DSTI's has
registered patents for its technology in Guatemala (patent No 5032) and in other
countries. 


The 100% owned Rio Negro nickel project consists of one 44 km2 exploration
license where nickel mineralization is within a weathered profile averaging 20
to 30 metres in thickness with nickel values around 1.5% Ni. Comprehensive
exploration work was carried out in the 1970's and yielded 2,320 samples from
226 exploration pits. From this work, a series of historic resource estimates
were generated; by Cominco, in 1980 (25.9 million tonnes grading 1.5% Ni) &
Tombstone Exploration in 1997 (40.2 million tonnes grading 1.24% Ni). All
historical resources are categorized as Inferred resources using the meaning
ascribed to that term by the Canadian Institute of Mining (CIM), due to the
uncertainty which may attach to Inferred Mineral Resources, it cannot be assumed
that all or any part of an Inferred Mineral Resources will be upgraded to an
Indicated or Measured Mineral Resource as a result of continued exploration. A
qualified person has not done sufficient work to classify the historical
estimate as current mineral resources and DSTI is not treating the historical
resources as current mineral resources. Confidence in the historical estimates
is insufficient to allow the meaningful application of technical and economic
parameters or to enable an evaluation of economic viability. 


DSTI Quality Assurance/Quality Control procedures follow standard industry
practices. Sealed bags are transported from the sample site by qualified
geological technicians. Sample intervals are selected according to geologic
contacts, visible mineralization and alteration. Samples are stored in a secure
building. Samples are placed into sample bags, sealed and shipped to an assay
lab that follows ISO 9000 series of Quality Management standards or in this
case, to DSTI Thetford Mines facility for analysis by ICP plasma.


The technical information in this press release was prepared and approved by
Jean-Philippe Mai, P.Geo, a "qualified person" as defined in National Instrument
43-101.


Cautionary Notes

This press release refers to historical exploration results. These are derived
from historical company reports. The Corporation has not independently verified
and make no representations as to the accuracy of historical exploration
results. Selected results and resources may not be indicative of average grades

About Dundee Sustainable Technologies, a company controlled by Dundee Corporation

The cyanide and mercury free gold extraction process developed by DSTI, has been
recognized as a "green technology" for which DSTI has been awarded $5,700,000 in
grants to date for a demonstration plant, presently under construction in
Thetford Mines Quebec of which $700,000 has been provided by the Government of
Quebec and $5,000,000 by the Government of Canada through the Sustainable
Development Technology Fund. The plant is scheduled to go into operation in
mid-January 2015.


Over the last ten years DSTI has tested over 50 different gold deposits, both
oxide and sulfide ores at the lab level and at its pilot plant. These tests
have, consistently achieved gold recoveries in excess of 90%, using chlorination
instead of cyanide. In addition, the tailings from the process are inert from
toxic substances and as result meet environmental norms. An engineering study
completed within the last 12 months supports DSTI's claim of having operated a
pilot plant showing a gold extraction yield higher than 90% using a
closed-circuit chlorination process.


FORWARD LOOKING STATEMENTS: This press release contains forward-looking
statements that address future events and conditions, which are subject to
various risks and uncertainties. Actual results could differ materially from
those anticipated in such forward- looking statements as a result of numerous
factors, some of which may be beyond the Corporation's control. These factors
include: results of exploration activities, general market and industry
conditions, and other risks disclosed in the Corporation's filings with Canadian
Securities Regulators.


Forward-looking statements are based on the expectations and opinions of the

used in the preparation of such statements, although considered reasonable at
