EURO SUN INCREASES GOLD RECOVERY TO 82% FROM 72% AT ITS
ROVINA VALLEY PROJECT WITHOUT THE USE OF CYANIDE
April 25, 2017
Toronto, Ontario
Euro Sun Mining Inc., (TSX: ESM) (“Euro Sun” or the “Company”) is pleased to report that gold
recovery to concentrate has increased from 72% to 82% utilizing new metallurgical test work on
mineralized material from its gold and copper Rovina Valley Project (the “Project” or “RVP” )
located in east-central Romania. The new management of Euro Sun initiated a new metallurgical
study by Eriez Flotation Division (“Eriez”), a leading flotation engineering firm based in Erie,
Pennsylvania, using their proprietary column cell technology.
Highlights from the metallurgical test program include:
Gold recovery ranging from 81.4% to 82.1%
at a gold concentrate grade of 109.1 g/t to 118.6 g/t
Copper recovery ranging from 86.9% to 88.9%
at a copper concentrate grade of 19.48% to 21.31%
No Cyanide is used in any of the current test work
nor will it be contemplated for the Project
Current open circuit testing sees a likely bump
in recovery once closed circuit testing is completed
G. Scott Moore, President and CEO of Euro Sun Mining stated, “We are very pleased with the
results from these tests, which indicate that we will be able to produce a saleable copper
concentrate. The recoveries and concentrate grades from these tests surpassed the results from
all previous tests, and we believe this demonstrates an increase in the economic value of the ore,
which will positively impact several aspects of the project in our feasibility study.”
The metallurgical test work was conducted on a master composite from the Colnic gold and
copper porphyry mineral deposit.

Corporate Update
Feasibility Study
Euro Sun has received several proposals for the completion of a feasibility study on the
development of Phase I of the Rovina Valley Project. The Company expects to announce a
successful bidder in the coming weeks.
Permitting
Euro Sun received a mining licence from the Romanian National Agency for Mineral Resources
(“NAMR”) in May, 2015, signifying an important transitional milestone from the exploration stage
to the exploitation phase. Th e Company is working diligently to have the mining licence ratified
by the four required ministries (Environment, Economy, Justice and Finance) , and published in
the government gazette.
Since the legislative elections held on December 2016, the Romanian government has reshuffled
the cabinet twice. The latest change, in April 2017, included a new Environmental Minister. As
such, three of the four required Ministe rs have been changed in the first 90 days of the new
government. This has unfortunately set back our efforts in getting the licence ratified in the first
quarter of 2017, since any ministerial changes require us to restart the ratification process. We
are working diligently with NAMR to get the ratification process initiated now that all four ministers
are in place and not likely to be changed in the near term.
Euro Sun has gained strong local support for the Rovina Valley Project, evidenced by written
letters of support from all the local communities around the project in addition to the neighbouring
county of Hunedoara.
Once the mining licence is ratified, Euro Sun can move ahead with the completion of an
Environmental and Social Impact Assessment on the Rovina Valley Project, which the Company
expect to complete in parallel with the feasibility study.
Exploration
Field work is on-going on the Stanija prospect (located approximately 3km from the Rovina Valley
Project), with an extensive exploration program outlined for this quarter. Following a review of
these results, the Company will determine whether drilling is merited under the prospecting
permit.
Qualified Persons
The scientific and technical information pertaining to the metallurgical studies presented in this
press release has been reviewed and approved by Joseph C. Milbourne, Vice President Technical
Services for Euro Sun, who is a Qualified Persons as defined by National Instrument 43-101.
