NEWS RELEASE TSXV: NEXG; OTCQX: NXGCF July 9, 2026

NexGold Intersects 12.06 g/t Gold over 6.0 Metres and 3.84

g/t Gold over 18.0 Metres During Infill Drill Program at

Goldboro

TORONTO, July 9, 2026 – NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) (“NexGold” or the

“Company”) is pleased to report additional assay results from its ongoing Reverse Circulation (“RC”) infill

drill program (the “RC Infill Drill Program”) at the Company’s Goldboro Gold Project (“Goldboro” or the

“Goldboro Project”) in Nova Scotia. Based on the success of the program to date and the potential to

further enhance confidence in near-surface mineralization, the Company has elected to expand the RC

Infill Drill Program from approximately 30,000 metres to 40,000 metres.

The RC Infill Drill Program is focused on selected areas of the Goldboro Deposit and is designed to infill

specific areas of the Goldboro Mineral Resource within the West and East pits 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: “ I am encouraged by the results

generated to date from our RC Infill Drill Program at Goldboro . The drilling continues to confirm the

continuity, tenor and thickness of near -surface mineralization within the proposed W est pit area at a

higher level of detail. The program is also providing additional geological and grade information in areas

that are currently contemplated in the early years of the Goldboro mine plan. Given the success of the

program to date, combined wi th the proceeds from our recently -completed C$10 million flow- through

financing, we have elected to expand the RC Infill Drill P rogram to further evaluate and better define

near-surface mineralization within the West and East pits.

“The information generated through this program is expected to support ongoing geological modelling,

Mineral Resources refinement, and mine planning activities at Goldboro, while also informing the

Company’s evaluation of a potential construction decision on the project. The expanded program is

approximately 62% complete and is expected to continue into the fourth quarter of 2026. We look forward

to providing further updates as additional assay results become available.”

Drill results in this news release represent 3,420 metres of drilling from 72 RC drill holes (RC-26-084 to

RC-26-152, RC -26-197, RC-26-206 and RC- 26-207) from the west pit ( Table 1 ). Cumulatively, the

Company has released results for 154 drill holes representing a total of 6,685 metres, with additional

holes pending assay and more arriving to the lab daily . 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 I-S (Figure 3). A full table of significant gold intersections are provided in Table 2 below.

Selected highlights from the RC Infill Drill Program include:

• 12.06 g/t Au over 6.0 m etres (from 44.0 m etres to 50.0 m etres), including 67.41 g/t Au over

1.0 metres (from 47.0 metres to 48.0 metres) in drill hole RC-26-147;

• 3.84 g/t Au over 18.0 m etres (from 30.0 m etres to 48.0 m etres), including 28.04 g/t Au over

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 RC 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.

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.
