Vancouver - Goldsource Mines Inc. (TSXV: GXS) (OTCQB: GXSFF) (FSE: G5MA) ('Goldsource' or the 'Company') is pleased to announce additional infill and expansion drill results for the Company's 100%-owned Eagle Mountain Gold Project in Guyana, South America.

Newly reported results are for 55 core holes totaling 7,886 metres from the Friendly, Bacchus, Bottle Bank, No. 1 Hill and Baboon areas of the Eagle Mountain deposit, which is defined by a series of sub-horizontal mineralized zones that are laterally extensive and start at surface.

The Company's focus through the first nine months of 2021 was to complete infill and expansion drilling of the Eagle Mountain deposit in preparation for an updated Mineral Resource Estimate ('MRE'). This drilling was designed to upgrade a significant portion of current near-surface Inferred Mineral Resources to the Indicated category through infill drilling and to test for lateral and depth extensions through expansion drilling. The results reported in this release constitute most of the remaining infill and expansion holes planned for the 2021 program.

Since November 6, 2020, the cut-off date for the February 2021 MRE ('February MRE'), the Company has completed 17,449 metres of infill and expansion drilling in 155 core holes (average depth of 113 metres) at the Eagle Mountain deposit and remains on track for an updated MRE later in 2021. The February MRE is contained in a report titled, 'Eagle Mountain Gold Project, Potaro - Siparuni Region Guyana, NI 43-101 Technical Report,' dated April 7, 2021 with an Effective Date of February 17, 2021.

With the infill and expansion drilling of the Eagle Mountain deposit substantially complete, the Company has re-initiated exploration activities, drill testing known geophysical targets and following up on prospects along the north-south Salbora-Powis structural trend. This 5,000-metre exploration program was detailed in the Company's August 12, 2021 News Release. Drill results for these activities will follow in a separate release when analytical results have been received and evaluated.

Steve Parsons, P. Eng., and CEO of Goldsource, commented, 'Our exploration activities through much of 2021 have focused on confirming and extending the shallow mineralized horizons of the Eagle Mountain deposit, initially focusing on the thicker zones of mineralization in the core areas, such as Ounce Hill, Bottle Bank, Zion, and Kilroy, and more recently moving to the flanks of the deposit to test for lateral extensions to the north, southwest and at depth in the Bacchus and Baboon/No.1 Hill areas, respectively. In all, with drilling through October, including some follow-up at the Salbora deposit, we expect to be well positioned to deliver on another key objective, that is, to upgrade a significant portion of Inferred Resources to the Indicated category. This updated Indicated resource will then be used as the basis for a prefeasibility study ('PFS') focusing on establishing a shallow, low strip open-pittable mineral reserve. Confirming the economic potential of Eagle Mountain by way of a PFS is a critical step for the Company.'

'Drilling will continue, however, as the property is still relatively underexplored, both along the Salbora-Powis trend and on the eastern side of the Prospecting License. The Salbora-Powis trend is currently the subject of a 5,000-metre program, which kicked off in September and will continue into early December. We look forward to sharing these results as assays become available.'
