NexGold Infill Drilling Intersects 1.60 g/t Gold Over 36.80 Metres at the Goldboro Gold Project

TORONTO, June 19, 2025 (GLOBE NEWSWIRE) -- NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) ("NexGold” or the "Company”) is pleased to provide an update on its ongoing 25,000-metre diamond drill program initially announced on January 22, 2025 at the Company's Goldboro Gold Project in Nova Scotia ("Goldboro”). The drill program is primarily designed to infill specific areas of the open pit Mineral Resource identified to improve geological and grade continuity and potentially upgrade certain areas of Inferred and Indicated Mineral Resources. The drilling is progressing well with two active diamond drills. The drilling is anticipated to be completed at the end of Q2 with final assays flowing in through the middle of Q3.

The assay results for an additional 11 infill diamond drill holes (BR-25-476, 480, 484, 487, 490, 493, 496, 499, 504, 507 and 512), totalling 3,063.00 metres, were from drilling in the proposed west pit (Figure 1; Table 1).

Kevin Bullock, President and CEO, stated: "With the 25,000-metre diamond drill program nearly complete and as we continue to receive assay data, we are encouraged by the results and their potential to positively impact the planned Mineral Resource update by providing more confidence through increased data density in certain areas of the deposit and the potential to add more mineralization in previously under-sampled intervals. Populating the Mineral Resource with additional geological and assay data will provide the basis of the planned Feasibility Study update. The Feasibility Study update will be ongoing while we await the final decision on the Nova Scotia Industrial Approval for the Project, having recently received the Notice of Completion regarding the Company's Industrial Approval application - a significant milestone in the permitting of the Goldboro Gold Project. Both permitting and technical studies are well aligned for timing a construction decision in 2026.”

Selected drill intersections from 11 diamond drill holes in this release include:

• 1.60 g/t gold over 36.80 metres (from 271.20 to 308.0 metres) including 53.57 g/t gold over 0.60 metres in drill hole BR-25-504;
• 0.83 g/t gold over 32.55 metres (from 234.50 to 267.05 metres) including 6.00 g/t gold over 1.60 metres in drill hole BR-25-504;
• 0.61 g/t gold over 21.80 metres (from 209.00 to 230.80 metres), including 6.06 g/t gold over 0.60 metres in drill hole BR-25-507;
• 0.91 g/t gold over 12.30 metres (from 238.60 to 250.90 metres), including 1.42 g/t gold over 7.20 metres in drill hole BR-25-507;
• 2.47 g/t gold over 4.65 metres (from 266.55 to 271.20 metres), including 9.55 g/t gold over 1.00 metre in drill hole BR-25-484; and
• 3.36 g/t gold over 3.60 metres (from 205.40 to 209.00 metres), including 14.70 g/t gold over 0.80 metres in drill hole BR-25-484.

The Company has now released 42 drill holes (approximately 30% of the proposed program) from the infill program. Results from the drill program to date for the drilling conducted in the proposed west pit demonstrate the presence of mineralization that is consistent with previous drill results. In particular, the existing geological model appears to broadly predict the location of gold mineralization with local adjustments to the model where mineralization is either not in the exact positions predicted by the model or if no mineralization is intersected. Significantly, the drill program continues to intersect additional gold mineralization in areas where no mineralization was previously known or predicted. This occurs either in under-drilled areas or near historic drilling which were not thoroughly sampled. Mineralized solids will be adjusted where necessary to account for local variations in the model, and any impact due to additional assay data gathered during the drill program will be investigated during the forthcoming Mineral Resource estimate planned during H2 2025.

Notes:

1. Drill hole locations reported as Universal Transverse Mercator NAD83 Zone 20 coordinates.
2. Some drill hole numbers are missing from the sequence. These drill holes are not reported in this press release since they were drilled in another location and will be reported in a separate release with other contiguous or related drilling information.
3. Drill holes BR-25-466 to 475, 479, 498 and 501 were reported in previous press releases dated May 16 and June 5, 2025.
4. Drill holes BR-25-477, 478, 481 to 483, 486, 489, 491, 495, 502, 505, 508, 510, 513, 518, 520, 522, and 524 were reported in a previous press release dated June 13, 2025.
