NexGold Intersects 61.22 g/t Gold over 12.0 Metres and 5.85 g/t Gold over 13.0

Metres During Infill Drill Program at the Goldboro Gold Project in Nova Scotia

TORONTO, June 25, 2026 -- NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) (“NexGold” or the “Company”) is

pleased to provide initial results from its detailed Reverse Circulation infill drill program (“ RC Infill Drill Program ”) at the

Company’s Goldboro Gold Project in Nova Scotia (“ Goldboro Project ”). The RC Infill Drill Program, which comprises up to

30,000 metres in 600 holes, is focused on the Goldboro Deposit and is designed to infill specific areas of the Goldboro Mineral

Resource at a nominal drill spacing of 12.5 metres and down to depths of 50 metres (Figures 1 and 2).

Kevin Bullock, President, CEO & Director of NexGold, commented: “The RC Infill Drill Program is progressing very well, with

over 65% of the drilling complete. Initial results from the program are confirming the location, tenor of gold grade, and

thickness of mineralization at a level of detail not previously drilled at Goldboro, and within the western most areas coincident

with the first years of mining.

“The Company continues to advance and strengthen the Goldboro Project as we move toward an investment decision later this

year. The aim of the current infill drill program is to further de-risk the Mineral Resources and Reserves for the Project, with a

focus on areas of the Mineral Resource that are expected to be mined in the early years of production, coincident with the

anticipated pay-back window. These drill results will assist in informing a final investment decision expected later this year and

will be incorporated in any future Mineral Resource Estimate beyond the updated Feasibility Study expected to be completed

in late Q3 of this year.

“We anticipate the RC Infill Drill Program to continue into Q3 of 2026, and look forward to updating the market as assay results

become available, subject to ongoing drilling progress, laboratory turnaround times and other factors.”

This high-density RC Infill Drill Program targets the first few years of planned production at the Goldboro Project where it is

currently accessible by the drill rig. The goal of the drill program, and the rationale for using Reverse Circulation drilling, is to

obtain a high-density data set that may be used to ultimately upgrade Mineral Resources from the Indicated to Measured

category, using a drilling technique that more closely approximates production drilling and associated dilution. This information

will be used in concert with more than 180,000 metres of diamond drill data currently available on the deposit to inform the first

years of planned mining activity.

Drill results in this press release represent 3,265 m of drilling from 82 RC drill holes ( Table 1 ). Based on QA/QC procedures

and data as well as comparisons to previous drilling and recent modelling, the drill results are considered geologically

representative of mineralization. Drilling has intersected mineralization at Goldboro typical of the deposit and confirmed

mineralization at more detail but in similar tenor of grade and thickness as those intersected in diamond drill holes within the

same area but at a broader spacing as shown on vertical cross sections A-H ( Figure 3 ). A full table of significant gold

intersections are provided in Table 2 below. Selected highlights from the RC Infill Drill Program include:

• 61.22 g/t gold over 12.0 m (from 18.0 m to 30.0 m), including 685 g/t gold over 1.0 m (from 23.0 m to 24.0 m) and

36.69 g/t gold over 1.0 m (from 24.0 m to 25.0 m) in drill hole RC-26-073;

• 5.85 g/t gold over 13.0 m (from 9.0 m to 22.0 m), including 61.2 g/t gold over 1.0 m (from 13.0 m to 14.0 m) in drill

hole RC-26-037;

• 3.72 g/t gold over 13.0 m (from 37.0 m to 50.0 m), including11.83 g/t gold over 1.0 m (from 47.0 m to 48.0 m) in drill

hole RC-26-060;

• 2.91 g/t gold over 9.0 m (from 20.0 m to 29.0 m), including 15.11 g/t gold over 1.0 m (from 21.0 m to 22.0 m) and 2.66

g/t gold over 8.0 m (from 42.0 m to 50.0 m) in drill hole RC-26-077;

• 4.02 g/t gold over 11.0 m (from 27.0 m to 38.0 m), including 37.4 g/t gold over 1.0 m (from 28.0 m to 29.0 m) in drill

hole RC-26-009;

• 6.39 g/t gold over 4.0 m (from 18.0 m to 22.0 m), including 17.6 g/t gold over 1.0 m (from 21.0 m to 22.0 m) in drill

hole RC-26-068;

• 6.10 g/t gold over 4.0 m (from 42.0 m to 46.0 m), including 23.65 g/t gold over 1.0 m (from 43.0 m to 44.0 m) and 1.15

g/t gold over 10.0 m (from 7.0 m to 17.0 m) in drill hole RC-26-036;

• 5.73 g/t gold over 5.0 m (from 39.0 m to 44.0 m), including 13.78 g/t gold over 1.0 m (from 42.0 m to 43.0 m) in drill

hole RC-26-028;

• 2.17 g/t gold over 13.0 m (from 33.0 m to 46.0 m) in drill hole RC-26-040; and

• 1.75 g/t gold over 16.0 m (from 13.0 m to 29.0 m), including 16.82 g/t gold over 1.0 m (from 15.0 m to 16.0 m) in drill

hole RC-26-032.

The Company expects to include the results of the RC Infill Drill Program in a future updated Mineral Resource Estimate that

is independent of the ongoing updated Feasibility Study. As the updated Feasibility Study is estimated to be completed in Q3

2026, and this RC Infill Drill Program is still ongoing, the information from this program is not available to inform the current

updated Goldboro Mineral Resource Estimate within the Feasibility Study timeframe. The Company previously completed a

technical report on the Goldboro Project prepared by Nordmin Engineering Ltd., entitled “NI 43-101 Technical Report and

Feasibility Study for the Goldboro Gold Project, Eastern Goldfields District, Nova Scotia” with an effective date of December

16, 2021 and a report date of January 11, 2022 (the “2021 Feasibility Study”). The technical report is available on SEDAR+

at www.sedarplus.ca and on the Company’s website at www.nexgold.com.
