VANCOUVER, BC – April 5, 2018 – Goldsource Mines Inc. (“Goldsource” or the “Company”) is pleased to announce that on March 29, 2018, the Company, through its subsidiary and with its local joint venture partner in Guyana, Kilroy Mining Inc., executed a definitive agreement with a local Guyanese individual (the “Owner”) for the option to explore and purchase a 100% interest in the Bishop Growler Property (“Bishop Growler” or the “Property”).

As announced on February 1, 2018, Bishop Growler is located along the projected mineralized trend three (3) kilometres from the Company’s 100% owned Eagle Mountain Gold Project (“Eagle Mountain”) in Guyana, South America and it is surrounded by Eagle Mountain’s existing 5,030-hectare Prospecting Licence (“EMPL”).

Yannis Tsitos, President, commented, “We are pleased to have concluded this definitive agreement to exclusively explore this strategic land package proximal to Eagle Mountain. Together with our surrounding prospecting licence, it provides access to this northeastern gold mineralized trend, which has never been systematically explored or drilled, but has returned surface grab and rock samples with values as high as 80 gpt gold (Eagle Mountian Gold Corp historical database, 2012 – see attached Figure). We have now initiated an exploration program at Bishop Growler, which includes geological mapping, auger and diamond core drilling at selected locations, geochemical sampling along trenches and sampling of historical artisanal gravity tailings. We plan to include results from this exploration program at Bishop Growler and the neighboring EMPL areas in the Company’s upcoming revised resource estimate.”

Bishop Growler consists of one Mining Permit Medium Scale (“MPMS”) and covers an area of about 2.5 square kilometres. The 15 Small Scale Mining Claims described in the Company’s news release of February 1, 2018 have been converted into this single MPMS which is currently valid and in good standing.

Pursuant to the definitive agreement, the Company can earn a 100% interest in the Property by making the following payments:

• US$75,000 upon execution of the definitive agreement (paid);
• US$150,000 in January 2019;
• US$150,000 in January 2020;
• US$150,000 in January 2021; and
• US$500,000 upon exercise of the option.

As additional consideration for the purchase of the Property, the Owner will be entitled to receive, an alternative piece of artisanal mining property in the vicinity of Eagle Mountain, no less in area than the size of Bishop Growler, provided that the determination of the location of such area shall be at the exclusive discretion of the Company.

The Option can be terminated without cost at any time on one-months’ notice.
