Goldsource Mines Inc. Announces High-Grade Drill Results at Eagle Mountain

Drilling at the Eagle Mountain Project recommenced in early January after the holiday break. One core rig is focused on in-fill drilling of gold mineralization at the Eagle Mountain Deposit while a second is testing both new exploration and existing expansion targets near the Eagle Mountain Deposit and along the Salbora-Powis Trend. A third core rig is scheduled to resume later in February.

An objective of the drill program in early 2021 was to test the continuity of near-surface saprolite gold mineralization in the Ounce Hill Prospect, located in the northeast of the Eagle Mountain Deposit (Figure 1). In-fill drill holes EMM21-007 and EMM21-008 targeted an area that had previously been drilled on a wide spacing (greater than 50 metres) returned grades well above prior results (see below for table of Ounce Hill historic intercepts). EMM21-007 represents the highest-grade x thickness intercept drilled at the Eagle Mountain Project to date.

Highlights (Ounce Hill Prospect)

• Starting from surface, in-fill hole EMM21-007 intersected 42.0 metres (est. true width of 34.0 metres) grading 20.38 grams per tonne ("gpt") gold ( "Au"), including a high-grade intercept of 3.0 metres (est. true width of 2.4 metres) grading 205.98 gpt Au at the base of the saprolite (Figure 3).
• In-fill hole EMM21-008, drilled from the same pad as EMM21-007 but oriented to the southeast, intersected 30.0 metres (est. true width of 24.0 metres) grading 3.41 gpt Au from surface, also in saprolite.
• Step-out drill holes EMM21-004 and EMM21-005, targeting lateral extensions of saprolite mineralization in the Ounce Hill Prospect, intersected gold mineralization approximately 60.0 metres west of the 2014 PEA⁽¹⁾ pit outline (Figure 2). EMM21-004 intersected 6.0 metres grading 0.72 gpt Au and EMM21-005 intersected 16.5 metres grading 0.84 gpt Au, both demonstrating potential for continued lateral extensions of the sub-horizontal mineralized zones in the prospect.

Yannis Tsitos, President of Goldsource Mines, commented "in terms of thickness x grade profile, EMM21-007 is the best hole drilled at the Eagle Mountain Gold Project to date, topping the 2019 discovery hole at Salbora, which intersected 40 metres (true width) grading 6.52 gpt Au from surface. Importantly, this record hole demonstrates the potential for further high-grade zones within the Eagle Mountain Deposit. This and recent announcements on Hill No. 1 and Baboon Area lateral extensions of the sub-horizontal mineralization bode well for potential resource growth at Eagle Mountain".

Steve Parsons, P. Eng, and CEO of Goldsource, added, "2021 is off to a very encouraging start for Goldsource. With new high-grade drill results and a resource update for the Eagle Mountain Project due to be released in February, we expect to be in a position to showcase the scale potential and quality of Eagle Mountain. These new drill results will not be included in the upcoming resource update; however, it will include results from the approximately 34,000 metres of drilling completed since the last resource estimate in 2014."

The following table shows the most significant results (uncut, undiluted):

Eagle Mountain Deposit - Ounce Hill In-fill Intercepts:

Note: All numbers rounded.

(1) EMM defines core holes completed by drilling contractor (man-portable rig).
(2) True widths are estimated to be 70 to 100% of drilled widths.
(3) Cut-off grade of 0.3 gpt Au.

All sample preparation and geochemical analyses were completed by Actlabs Guyana Inc. in Georgetown, Guyana. Hole EMM21-004b was abandoned at 31.0 metres due to poor recovery, assays intersected mineralization below the Company's cut off grade of 0.3 gpt Au.

Eagle Mountain Deposit - Ounce Hill Geology

The Ounce Hill Prospect hosts high-grade mineralization in the upper sub-horizontal dip-slope mylonite (shear) zone, which is referred to as Zone 1 (Figure 3). These higher-grade zones are generally 100 metres x 100 metres on surface and can be 30 to 50 metres in depth. In both the Ounce Hill and Zion areas these higher-grade zones are almost entirely within the oxidised (saprolitic) zone. Historically, several holes in this area have returned high-grade assays, with typical characteristics of increasing gold grade towards a silicified mylonite base. For example, historical drill hole EM99-052, located approximately 25 metres to east and on section with new drill holes EMM21-007 and EMM21-008, intersected 27.7 metres (est. true width) grading 5.31 gpt (Figure 3). Drill holes EMM21-007 and EMM21-008 have confirmed and extended this high-grade feature. Follow-up drilling is planned in H1 2021 to test its lateral extent.

Historic drill holes for the Ounce Hill Prospect are presented in the table below.

EMD08 defines diamond core holes completed by IAMGOLD in 2008.
EMD11 defines diamond core holes completed by Stronghold in 2011.
EM99 defines diamond core holes completed by Omai Gold Mines in 1999.
EM0 defines diamond core holes drilled by Golden Star Resources in the 1990s.
(2) True widths are estimates to be 70 to 100% of drilled widths.
(3) Cut-off grade of 0.3 gpt Au.
(4) These results were used for resource estimation in the Preliminary Economic Assessment of the Eagle Mountain Saprolite Gold Prospect, Guyana, June 15, 2014.

An updated Mineral Resource Estimate is currently being finalized and is expected to be announced in the coming weeks. Subsequently, a NI 43-101 Technical Report will be filed on SEDAR within 90 days of the resource announcement. This is an extension from 45 days pursuant to the temporary changes in filing requirements as a result of COVID-19. The cut-off date for the upcoming Mineral Resource Estimate was November 6, 2020. Drill results released after this date will not be included in the upcoming estimate; rather, they will be included in a subsequent resource update that is planned for H2 2021, following the conclusion of the in-fill drilling program.
