Euro Sun Increases Gold Recovery to 82% from 72% at Its Romania Rovina Valley Project Without the Use of Cyanide

Euro Sun Mining Inc., announced 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 located in east-central Romania. The new management of Euro Sun initiated a new metallurgical study by Eriez Flotation Division, a leading flotation engineering firm based in Erie, Pennsylvania, using their proprietary column cell technology.

Highlights from the metallurgical test program include:

Supported by

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.

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.


Euro Sun received a mining licence from the Romanian National Agency for Mineral Resources in May, 2015, signifying an important transitional milestone from the exploration stage to the exploitation phase. The 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 Ministers 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.


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.
