Goldsource Reports High-Grade Results from Salbora and Initial Results from Bishop Growler; 2.0 m Grading 87.51 g/t Au
Vancouver, July 12, 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 and initial results for the Bishop Growler target at its Eagle Mountain Gold Project in Guyana (see attached Figures). The Company has received assay results from shallow auger drilling completed at Salbora, which is located approximately 1.5 kilometres northwest of the Eagle Mountain deposit. Results from the first 14 auger holes drilled in Salbora returned gold mineralization in four holes (AS18-136 to 139) with an average length and grade of 4.0 metres at 1.20 g/t gold from surface (see tables below). All holes bottom in mineralized saprolite. At Bishop Growler, the Company has received results from 28 shallow holes completed by the Geoprobe drill and 124 auger shallow holes. The most significant holes were EMC18-066 with 2.0 metres grading 87.51 g/t gold and EMC18-085 with 1.0 metre grading 13.60 g/t gold. Both holes intercepted near surface high-grade gold mineralization in saprolite. In-fill drilling at the main Eagle Mountain Deposit intercepted high-grade mineralization in several holes (see tables below). Yannis Tsitos, President, commented, "The additional results from Salbora, initial results from Bishop Growler, and in-fill drilling at the Eagle Mountain Deposit are encouraging and re-affirm the potential to expand the near surface saprolite gold resource at the Eagle Mountain Gold Project. While further assay results are pending, we continue with diamond drilling, auger drilling and trenching to follow up, both laterally and at depth, on the higher grade near surface mineralized saprolite intercepted in all defined targets. With continued success, the results from the ongoing drilling will be included in an updated Eagle Mountain resource by the end of 2018. Some deeper diamond holes are needed at Salbora and Bishop Growler to provide a better understanding of the gold mineralization and conceptual similarities to the main Eagle Mountain deposit."
The following tables summarize the most significant shallow auger and sonic core drill intercepts from the Salbora and Bishop Growler targets, as well as significant diamond core drilling intercepts from previously announced holes with outstanding analytical results from the Eagel Mountian deposit (uncut, undiluted):

Salbora Target (Discovery)
Goldsource has completed 63 shallow auger drill holes (totalling 232 metres of drilling) and 123 metres of trenching at Salbora, in addition to previously reported trench results (refer to Goldsource's News Release dated May 24, 2018). Assay results have been received for the first 14 auger drill holes. Assays for an additional 49 auger holes and 123 metres of trenching remain outstanding. All holes with gold mineralization were intercepted within two metres of surface in saprolite and are approximately 200 metres south of the discovery trench (TRSB18-002 with a length of 123 metres grading 1.92 g/t gold) previously announced on May 24, 2018. All holes ended in mineralization.
The Coolie area, immediately south of the Salbora area, has not yet been tested by Goldsource and historically intersected gold in diamond and auger drilling by IAMGOLD and Golden Star. These historic results are not included in the current NI43-101 resource. Gold at Coolie area was discovered concurrently with Eagle Mountain by Anaconda Mining in the 1940s. Inclusive of historical data, the Montgomery-Salbora-Coolie mineralized NNW-SSE zone extends approximately three kilometres in length. This target area warrants further exploration work including deeper diamond drilling to be initiated in H2, 2018.
Bishop Growler Target
Goldsource has received assay results from the first 28 shallow Geoprobe core and 124 shallow auger drill holes completed at the Bishop Growler target. Drilling has returned anomalous gold values with highlights including hole EMC18-066, which returned 2.0 metres grading 87.51 g/t gold and hole EMC18-085, which returned 1.0 metre grading 13.60 g/t gold. The Company has drilled four deeper diamond drill holes at Bishop Growler (196 metres of diamond drilling total), with assay results pending. High-grade near surface outcropping zones of gold mineralization suggest a NNW-SSE mineralized corridor at least two kilometres in length. The area warrants further and deeper drilling to determine whether a high-grade footprint can be delineated at Bishop Growler for inclusion in the updated resource estimate. Further work will be completed in H2, 2018.
Eagle Mountain Deposit
A preliminary internal model is being constructed for the main Eagle Mountain deposit using all data completed to date. This model will determine mineralized saprolite areas within the deposit requiring further drilling to convert Inferred Resources to Indicated Resource for the Pre-Feasibility Study. Further drilling is anticipated in H2, 2018 within the deposit.
Historical Auger Data from Salbora and Bishop Growler
The Company acquired the Eagle Mountain project from Omai Gold Mines Ltd in 2010, along with a historical database of shallow auger drill holes covering parts of the Eagle Mountain Prospecting Licence (5,000 acres). Shallow drilling had a maximum depth of two metres. Prior to the recent positive trenching results at Salbora (announced May 24, 2018) and the acquisition of the Option to Purchase the Bishop Growler Mining Permit (announced April 5, 2018), the Company analyzed historical drilling results for targeting purposes (see attached Figures). The following historical results from the database are considered the most significant auger intercepts (uncut, undiluted) for the designated targets:

The Company's initial results from Salbora and Bishop Growler are encouraging and warrant follow up exploration work to determine if resources can be delineated at both prospects in order to be incorporated into the ongoing Pre-Feasibility Study for the Eagle Mountain Gold Project. Subsequent to completion of this drill program, the Company plans to release an updated resource estimate in late 2018.
