Goldsource Expands Salbora Discovery at Eagle Mountain;

• 15 Metres Grading 3.84 g/t Au
• 28 metres Grading 2.88 g/t Au

Vancouver, British Columbia--(Newsfile Corp. - October 25, 2018) -  Goldsource Mines Inc. (TSXV: GXS) (OTCBB: GXSFF) (FWB: G5M) ("Goldsource" or the "Company") is pleased to report additional results from the ongoing exploration program at the Salbora target at its Eagle Mountain Gold Project in Guyana (see attached Figures). The Company has received assay results from additional shallow auger drilling, deeper Geoprobe sonic drilling and additional trenching completed at Salbora, which is located approximately 1.5 kilometres northwest of the Eagle Mountain deposit. Results from this additional work in saprolite has significantly expanded the mineralized footprint of this target which now measures approximately 500 metres in length and 100 metres wide and open in most directions. Exploration work will continue at Salbora to better define the mineralized envelope in this area in Q4, 2018.

Yannis Tsitos, President, commented, "The additional results from Salbora are encouraging and show potential to further expand the near surface saprolite gold resource at the Eagle Mountain Gold Project. We continue with drilling and trenching to follow up, both laterally and at depth, on the higher grade near surface mineralized saprolite intercepted in all defined targets. The results from the ongoing trenching and drilling will be included in an updated Eagle Mountain resource within the next 6 months. Deeper diamond holes are planned at Salbora to provide a better understanding of the gold mineralization and potential size of this new discovery."

The most significant result for drilling was EMC18-095 with 15.0 metres grading 3.84 grams per tonne ("g/t") gold (or "Au") and EMC18-094 with 17.0 metre grading 1.85 g/t gold. Both holes intercepted near surface high-grade gold mineralization in saprolite. The most significant result for trenching was TRBS18-005 with 28.0 metres grading 2.88 g/t gold and TRBS18-011 with 37.0 metres grading 1.70 g/t gold. The following table states the more significant results for this release (uncut, undiluted):

Salbora Geoprobe/Sonic Deeper Drill Holes

Salbora Hand Auger Shallow Drill Holes

Salbora Trenching

Notes for all tables: All numbers rounded. All reported holes are drilled vertical.
Assumed to be near-true widths.
*Cutoff grade of 0.3 g/t Au
**Core is by Geoprobe "Sonic" drill and depths are limited to the presence of groundwater horizon and floating boulders within the weathered saprolite layer. Auger holes are a maximum of 6 metres in depth.

All geochemical analyses were completed by Actlabs Guyana Inc. in Georgetown, Guyana.

The following are drill holes and trenches that were below the Compnay's cutoff grade; EMC18 -93, 100, 101, 103, 104, and 106, AS18-125 to 135, AS18-141 to 151, AS18-155 to 181, AS18-187 to 195, AS18-199 to 206, AS18-208 to 211, AS18-321 to 328 and AS18-328 to 333, TRSB18-003 to 004 and 007 to 008.

To date, Goldsource has completed 14 deeper core holes (160 metres), 100 shallow auger drill holes (380 metres) and 11 trenches (928 metres) at Salbora. All drill hole results with gold mineralization were intercepted within near surface within saprolite.

The Salbora discovery is located on a northwest-southeast regional trend with a minimum of 3 kilometres length and which is in alignment with significant historic alluvial gold operations. The Company plans to complete further exploration work including deeper diamond drilling to be initiated in Q4, 2018.

The Coolie area along the same trend as Salbora which is to the north has not yet been tested by Goldsource. Gold in saprolite and hard rock at the Coolie area was discovered concurrently with the Eagle Mountain deposit by Anaconda Mining in the 1940s. More recent (1995 to 2009) drilling by Golden Star and IAMGOLD discovered near surface high grade mineralization. Work by the Company is planned for Q4, 2018 for define extensions to Salbora.

The cumulative results from Salbora and the associated regional trend are encouraging and warrant follow up exploration work to determine if resources can be delineated for inclusion into the ongoing Pre-Feasibility Study for the Eagle Mountain Gold Project (see Company's news release dated May 24, 2018 and July 12, 2018). Subsequent to the completion of this drill program, the Company plans to release an updated resource estimate within the next 6 months.
