Euro Sun Awards Feasibility-Level Metallurgical Testing Contract FOR the Rovina Valley Project to Eriez USA
EURO SUN AWARDS FEASIBILITY-LEVEL METALLURGICAL
TESTING CONTRACT FOR THE ROVINA VALLEY PROJECT
TO ERIEZ USA
September 15, 2017
Toronto, Ontario
Euro Sun Mining Inc . (TSX: ESM) (“Euro Sun” or the “Company”) , reports that the feasibility-
level metallurgical testing contract for its Rovina Valley Gold and Copper Project has been
awarded to Eriez Flotation Division , USA (“Eriez”). SRK Consulting (Canada) Inc will oversee
the metallurgical test program at Eriez as part of the Bankable Feasibility Study. The test work
will follow on the previous metallurgical results released in April 2017 (see press release dated
April 26, 2017).
G. Scott Moore, President and CEO of Euro Sun Mining, commented, " The feasibility level
metallurgical test work will follow on and confirm the outstanding results reported in April of
2017, wherein gold recoveries increased to 82% and copper to 88% in a 21% copper
concentrate, all without the use of cyanide.”
The metallurgical test work is to employ column flotation technology to investigate the optimal
grade and recovery relationship for copper and gold within both the Colnic and Rovina geo -
metallurgical domains. A copper concentrate grade of 18 -20% is targeted for treatment of all
ores. Coarse flotation using the Eriez HydroFloatTM will also be investigated in an effort to
minimize the grinding requirements and maximize rejection of coarse clean tailings.
A total of four feed samples spanning four geo -metallurgical domains, three Colnic and one
Rovina, will be provided by Euro Sun Mining. Sampl es are expected to arrive as core (3,000 kg
per sample); therefore crushing, classification, and milling will precede all flotation testing.
Following identification of the most optimal rougher flotation feed grind size via mechanical
flotation tests, samples will be bulk milled to the appropriate P80 size and subjected to rougher -
scavenger column flotation in series. Following primary column flotation optimization and
treatment of each bulk sample, secondary grinding studies will be conducted on rougher -
scavenger concentrates to determine grinding times necessary to achieve P80 grind sizes of 38
and 25 µm. Locked cycle, or closed circuit, cleaner flotation testing will be performed using
Eriez’ automated multi-stage column flotation circuit.
The laboratory-scale columns will be run with automatic level control and include the proprietary
Cavitation-Tube sparging technology. The high collision rates afforded by the Cavitation -Tube
sparging system ensure excellent recovery of fine and ultra -fine material. In addition, the use of
wash water is expected to improve flotation grade by limiting entrainment.

About Euro Sun Mining Inc.
Euro Sun is a Toronto Stock Exchange listed mining company focused on the exploration an d
development of its 100%-owned Rovina Valley Gold and Copper Project located in west-central
Romania. The property hosts 10.84 million gold equivalent ounces (7.19 million ounces of gold
grading 0.55 g/t and 1,420 million pounds of copper grading 0.16%*), making it the second
largest gold deposit in Europe.
*Notes Related to the Mineral Resource Estimate : Gold equivalent ounces (“AuEq”) are
determined by using a gold price of US$1,370/oz and a copper price of US$3.52/lb. These
prices are the three -year trailing average as of July 10, 2012. Metallurgical recoveries are not
taken into account for AuEq. Base case cut-off used in the table are 0.35 g/t AuEq for the Colnic
deposit and 0.25% CuEq for the Rovina deposit, both of which are amenable to open -pit mining
and 0.65 g/t AuEq for the Ciresata deposit which is amenable to underground bulk mining. For
the Rovina and Colnic porphyries, the resource is an in-pit resource derived from a Whittle Shell
Model using gross metal values of $1,350/oz Au price and $3.00/lb Cu price, net of payable
amounts after smelter charges and royalty for net values of US$1,313/oz Au and US$2.57/lb Cu
for Rovina and US$2.27/Ib Cu for Colnic). Rounding of tonnes as required by reporting
guidelines may result in apparent differences between tonnes, grade, and contained metal
content.

Pierre Desautels, P.Geo. Principal Resource Geologist of AGP, who served as the independent
