NexGold Mining Corp. (TSX-V: NEXG) (OTCQX: NXGCF) is pleased to provide additional results from the ongoing diamond drilling program at the Company’s Goliath Gold Complex, which includes the Goliath, Goldlund and Miller Deposits. The drill program, of which approximately 18,000 metres have been completed of the planned 25,000 metres, is focused on the Goldlund Deposit, with holes designed to infill and potentially expand open pit Mineral Resources. The results presented in this news release include 3,663 metres of diamond drilling in nine drill holes (GL-25-012, GL-25-017 to GL-25-019, and GL-26-001 to GL-26-005). These drill holes infill and expand mineralization in Zone 4 of the Goldlund Deposit from near the centre to the southwestern end of the open pit Mineral Resource (Figures 1, 2 and 3; Tables 1 and 2).

Selected drill intersections from diamond drill holes at the Goldlund Deposit in this news release are further detailed in Table 1 and include:

• 14.10 g/t gold over 6.0 metres (from 53.0 to 59.0 metres), including 51.70 g/t gold over 1.5 metres and 4.59 g/t gold over 1.5 metres, in drill hole GL-26-003A; additionally, 2.99 g/t gold over 20.0 metres (from 157.0 to 177.0 metres), including 27.30 g/t gold over 1.0 metres and 24.90 g/t gold over 1.0 metres; and 10.67 g/t gold over 7.0 metres (from 189.0 to 196.0 metres), including 143.00 g/t gold over 0.5 metres in the same hole;
• 4.25 g/t gold over 6.0 metres (from 302.0 to 308.0 metres), including 10.90 g/t gold over 1.0 metres in drill hole GL-26-002; additionally, 0.66 g/t gold over 43.0 metres (from 253.0 to 296.0 metres) including 14.80 g/t gold over 1.0 metres; additionally, 19.8 g/t gold was intersected over 0.6 metres (from 229.4 to 230.0 metres) in the same hole;
• 3.23 g/t gold over 6.0 metres (from 220.0 to 226.0 metres), including 17.30 g/t gold over 0.9 metres and 3.10 g/t gold over 1.0 metres in drill hole GL-25-017;
• 1.13 g/t gold over 20.0 metres (from 255.0 to 275.0 metres), including 13.40 g/t gold over 1.0 metres in drill hole GL-25-019; and
• 0.52 g/t gold over 55.9 metres (from 234.1 to 290.0 metres), including 8.43 g/t gold over 0.6 metres and 4.42 g/t gold over 1.0 metres in drill hole GL-25-018.

These drill results are in the same general area of Zone 4 mineralization where previously reported drill intersections were announced (see NexGold news release dated February 25, 2026) and included:

• 1.18 g/t gold over 33.5 metres (from 183.5 to 217.0 metres), including 18.00 g/t gold over 1.0 metres and 7.99 g/t gold over 1.0 metres in drill hole GL-25-009; additionally, 62.30 g/t gold was intersected over 1.0 metres (from 226.0 to 227.0 metres) in the same drill hole; and
• 1.03 g/t gold over 16.5 metres (from 350.5 to 367.0 metres), including 5.25 g/t gold over 0.8 metres and 4.34 g/t gold over 2.0 metres in drill hole GL-25-014; additionally, 28.9 g/t gold was intersected over 1.5 metres (from 129.5 to 131.0 metres) in the same drill hole.

Kevin Bullock, President and CEO of NexGold, commented: “Our infill drill program at the Goliath Gold Complex continues to demonstrate good continuity of mineralization at depth within the Goldlund Deposit. The drill results reported today are from the centre to southwestern portion of the Goldlund open pit and focused on the 100 to 300-metre levels of open pit Mineral Resources, and like previously reported results, continue to demonstrate a strong tenor of gold mineralization in this area.

Our objective with this drill program continues to be to optimize the Goliath Gold Complex and further strengthen our confidence in the mineralization within the deeper levels of the Inferred Mineral Resources. We expect this program to provide us with valuable information that will enable us to upgrade the Mineral Resource categorization at Goldlund. I look forward to sharing more drilling updates as exploration continues.”

Mineralization at the Goldlund Deposit is generally characterized by quartz stockwork veining within sub-vertical granodiorite sills. Zone 4 at the Goldlund Deposit includes broad intervals of mineralized intermediate-mafic volcanic rocks with multiple porphyry and granodiorite intrusions. The drill results summarized in this news release, together with previously announced drill results, provide additional support and information relevant to the interpretation of grade continuity within Zone 4. These results are expected to contribute to ongoing refinement of the geological model and may support future evaluation of Mineral Resource classification, subject to additional drilling, data verification, and completion of further technical studies.

Drill holes designed throughout this program have been distributed across the strike of Zone 4 with holes highlighted in this release located in the central to southwest end of the zone. These new hole s are near previously reported drill holes GL-25-009 and GL-25-014, which intersected 2.31 g/t gold over 21.5 metres and 2.34 g/t gold over 10.2 metres, respectively (see NexGold news release dated February 25, 2026). It has been observed that Zone 4 widens toward the southwest and has a tendency for mineralized features to be spread over a wider intersection. Gold intersected in these holes further demonstrates the continuity of mineralization and the potential for Mineral Resource expansion in Zone 4 as additional targets are drilled along strike and down dip.

QA / QC

The Company has implemented a quality assurance and quality control (QA/QC) program to ensure sampling and analysis of all exploration work is conducted in accordance with the CIM Exploration Best Practices Guidelines. The drill core is sawed in half with one-half of the core sample dispatched to Activation Laboratories Ltd. facility located in Dryden, Ontario. The other half of the core is retained for future assay verification and/or metallurgical testing. Other QA/QC procedures include the insertion of blanks and Canadian Reference Standards for every tenth sample in the sample stream. A quarter core duplicate is assayed every 20^th sample. The laboratory has its own QA/QC protocols, running standards and blanks with duplicate samples in each batch stream. Additional checks are routinely run on anomalous values including gravimetric analysis and pulp metallic screen fire assays. Gold analysis is conducted by lead collection, fire assay with atomic absorption, and/or gravimetric finish on a 50-gram sample. Check assays are conducted at a secondary ISO certified laboratory (in this case AGAT Laboratories located in Mississauga, Ontari o) following the completion of a program.
