Goldsource Mines Inc. (TSX-V: GXS) (OTCQB: GXSFF) (FSE: G5MA)  is pleased to announce additional exploration drill results for the Company’s 100%-owned Eagle Mountain Gold Project in Guyana, South America. Newly reported results are for seven core holes totaling 726 metres from the Toucan Prospect located approximately 1.3 kilometres northwest of Eagle Mountain (see attached Figures and Table below).

The results for this release are part of the 5,000-metre Phase-2 exploration program designed to test known geophysical and geochemical targets and follow up on prospects along the Salbora-Powis trend. This program was initiated in September and ramped up through November using drills that had previously been allocated to the Company’s larger infill and expansion program, which wrapped up in late October in preparation for an updated Mineral Resource Estimate.

The Toucan Prospect is located within the north-south trending Salbora-Powis structural corridor near the Eagle Mountain deposit (Figure 1). The recent drilling was designed to test the upward projections of the mineralized structures at Toucan and the potential for localized higher grades at the intersection of the primary sub-vertical breccia structures with sub-horizontal shear structures (zones), as was recently observed at the Salbora deposit (see news release dated November 17, 2021).

Toucan Area Highlights:

• Results for seven core holes totaling 726 metres are found in Table 1.
• Exploration hole EMD21-197 intersected 58.5 metres (estimated true width of 41.4 metres) grading 4.30 grams per tonne gold from surface. This included two intervals of high-grade gold mineralization within sub-horizontal zones on the east side of the Salbora-Powis trend.
  • 4.5 metres (ETW of 3.2 metres) grading 26.77 gpt gold starting at a downhole depth of 12.0 metres. This included a higher-grade sub-interval of 1.5 metres grading 79.26 gpt gold.
  • 34.5 metres (ETW of 24.4 metres) grading 3.62 gpt gold starting at a downhole depth of 24.0 metres. This included a higher-grade sub-interval of 9.0 metres grading 11.64 gpt gold at the intersection of a sub-vertical breccia structure and the base of the sub-horizontal zone.
• Approximately 25 metres north of EMD21-197, exploration hole EMD21-194 intersected 22.5 metres (ETW of 18.2 metres) grading 1.89 gpt gold starting at a downhole depth of 58.5 metres. This included a higher-grade sub-interval of 10.5 metres (ETW of 7.4 metres) grading 2.77 gpt gold.
• On the west side of the Salbora-Powis trend exploration hole EMD21-196 expanded the mineralized footprint, intersecting 21.0 metres (ETW of 14.8 metres) grading 1.13 gpt gold starting at a downhole depth of 25.5 metres. The interval included small irregular chlorite breccias at the base of the horizontal zone similar to those observed in EMD21-197.
• To capture the positive developments at the Toucan Prospect, specifically the higher-grade intervals and further delineation of the mineralized zones, the MRE update scheduled for late 2021 has now been rescheduled for early 2022. The Company anticipates an approximate one-month delay to apply modifications to the modelling of the Toucan Prospect for its inclusion in the MRE update.

Steve Parsons, P. Eng., and CEO of Goldsource, commented, “The Phase-2 program is progressing well with respect to the delineation of known prospects near Eagle Mountain, such as Toucan, and the development of new targets, which will be the subject of further drill testing in the coming months as the team focuses on higher-grade prospects to accompany the bulk tonnage shallow resource at the Eagle Mountain deposit. The Phase-2 program was initially planned for 5,000 metres. With several targets worthy of follow-up work and continuation of drier conditions with favourable drill productivity, the Company anticipates a Phase-2 total closer to 9,000 metres based on continued success. In terms of moving the MRE update to early 2022, as the recent drill results for Toucan were significantly better than expected, this will allow these results to be included in the upcoming MRE update.”

Kevin Pickett, Chief Geologist of Goldsource, added, “We are pleased to have completed follow-up drilling of the Toucan Prospect. The results have improved the drill density within the mineralized footprint and enhanced our understanding of the localized higher grades using key insights from our recent infill drilling of the Salbora deposit, which is situated within the same north-south structural corridor. On the exploration front, the team expect more drill results to be released in the coming weeks, potentially into early 2022, as assay results are received.”

Toucan Prospect (Salbora-Powis Trend)

Two styles of gold mineralization have been observed at the Toucan Prospect: (1) intervals of mineralization in a silicified granitoid with chloritic fractures and disseminated pyrite with a characteristic high-grade mineralized base, similar to sub-horizontal zones in the Eagle Mountain deposit; and (2) mineralization associated with chlorite and pyrite-filled breccias with silicic clasts characteristic of Salbora-style mineralization that occur in a sub-vertical orientation, striking approximately north-south.

In both Salbora and Toucan, the breccias interact with the sub-horizontal shearing with mineralizing fluids permeating along the shear which can give rise to locally higher-grade gold intervals. At Toucan this was observed for the higher-grade interval within EMD21-197 of 9.0 metres (ETW of 6.4 metres) grading 11.64 gpt gold on the east side of the Salbora-Powis structure (Figure 3). This was also observed for the first time on the west side of the Salbora-Powis structure in exploration hole EMD21-196, which intersected 21.0 metres (ETW of 14.8 metres) grading 1.13 gpt gold. While not high grade, the permeation of fluids along the shear has extended the mineralized footprint to the west and may suggest possible continuation of the sub-horizontal style of mineralization on the western flank of the Salbora-Powis trend, which will be tested in 2022.

Exploration drilling of the Toucan Prospect was designed to delineate the mineralized footprint, as defined in Figure 2, and to test for localized higher grades at the intersection of the two styles of mineralization. Presently, the mineralized footprint of Toucan is 90 metres wide over 180 metres of strike.

2021 Drill Program Overview

The four primary objectives for the 2021 drill program as set out below are substantially complete with the balance of the drilling for 2021 focusing on prospects along the Salbora-Powis trend. Toucan has been one of the primary targets of the Phase-2 exploration program. The other targets are earlier stage with assay results pending.

1. Infill drilling to upgrade a significant portion of the mineralization currently classified as Inferred to the Measured and Indicated categories. Re-classification to be used as the basis for a prefeasibility study, which is targeted to be delivered in 2022;
2. Testing for new lateral extensions of the sub-horizontal zones of the Eagle Mountain deposit, notably to the north, west and southwest outside of the February 22, 2021, MRE outline, as defined in Figure 1;
3. Follow-up exploration of several new target areas along the prospective Salbora-Powis trend, such as the Toucan, Powis, Ann and Montgomery prospects where the potential exists for Salbora-style mineralization; and
4. Using the above information, announce a MRE update in early 2022.
