NexGold Intersects 5.26 g/t Gold over 7.0 Metres and 7.08 g/t Gold over 5.0 Metres in RC Infill Drill Program at the Goldboro Gold Project, Nova Scotia

Drill Results Technical Reports (NI 43-101) Exploration Programs

TORONTO, Aug. 19, 2026 -- NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) (“NexGold” or the “Company”) is pleased to provide additional results from its 40,000-metre, 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 is focused on the Goldboro Deposit and is designed to infill specific areas of the Goldboro Mineral Resource within the planned 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: “The RC Infill Drill Program is progressing very well, with over 76% of the expanded drilling program complete. With our recently closed flow-through financing of $10M, we made the decision to increase the drilling program from 30,000 metres to 40,000 metres in order to further define Mineral Resources at shallow levels, consistent with the initial years of the mine plan within the west and east pits. We continue to see assay results that support the location, grade tenor and thickness of mineralization within the west pit at a level of detail not previously drilled at the Goldboro Project, including within the central area of the west pit that is scheduled for the initial years of mining.

“The Company continues to advance the Goldboro Project as we move toward a potential investment decision later this year. The objective of the current infill drill program is to further increase confidence in the Mineral Resources and Mineral Reserves supporting the Project, with a focus on areas of the Mineral Resource expected to be mined during the early years of production and within the anticipated payback period. These drill results are expected to support the evaluation of a final investment decision and may be incorporated into future Mineral Resource estimates beyond the updated Feasibility Study, which is expected to be completed later this year.

“We anticipate the RC Infill Drill Program will continue throughout Q3 2026 and look forward to providing updates as assay results become available, subject to drilling progress, laboratory turnaround times and other factors.”

The high-density RC Infill Drill Program targets areas of the Goldboro Project associated with the initial years of the current mine plan and that are presently accessible for drilling. The objective of the program, and the rationale for using Reverse Circulation (“RC”) drilling, is to obtain a high-density data set that may support future evaluation of the Mineral Resource for potential classification upgrades from the Indicated to Measured category, using a drilling technique that more closely approximates production drilling and associated dilution. The Company expects this information to be used in conjunction with more than 180,000 metres of existing diamond drill data to support planning and evaluation of the initial years of mining contemplated in the current mine plan.

Drill results in this news release represent 3,591 metres of drilling from 85 RC drill holes (RC-26-160 to 196, RC-26-199 to 205, RC-26-209 to 229 and RC26-254 to 258, 261, and RC-26-310 to 323) completed within the west pit area (Table 1). Based on QA/QC procedures and data, as well as comparisons with historical drilling and ongoing geological interpretation, the drill results are considered consistent with the Company’s current understanding of the mineralization. The drilling intersected mineralization consistent with the geological model for the Goldboro Deposit and provided additional definition of the mineralized zones at a higher drill density. Results show grade tenor and thickness as those intersected in diamond drill intersections in the same area, which were completed at wider spacing, as illustrated on vertical cross sections T-AD (Figure 3). A complete table of significant gold intersections is provided in Table 2 below. Selected highlights from the RC Infill Drill Program include:

  • 5.26 g/t Au over 7.0 m (from 41.0 m to 48.0 m), including 31.29 g/t Au over 1.0 m (from 44.0 to 45.0 m) in drill hole RC -26-226;
  • 7.08 g/t Au over 5.0 m (from 9.0 m to 14.0 m), including 25.11 g/t Au over 1.0 m in drill hole RC-26-195;
  • 14.97 g/t Au over 2.0 m (from 38.0 m to 40.0 m), including 29.62 g/t Au over 1.0 m and 0.90 g/t Au over 11.0 m (from 25.0 m to 36.0 m) in drill hole RC-26-163;
  • 5.42 g/t Au over 3.0 m (from 36.0 m to 39.0 m), including 15.69 g/t Au over 1.0 m, 5.10 g/t Au over 1.0 m (from 7.0 m to 8.0 m) and 1.09 g/t Au over 9.0 m (from 25.0 m to 34.0 m) in drill hole RC-26-168;
  • 1.10 g/t Au over 10.0 m (from 7.0 m to 17.0 m) and 2.44 g/t Au over 4.0 m (from 33.0 m to 37.0 m) in drill hole RC-26 -223;
  • 18.54 g/t Au over 1.0 m (from 16.0 m to 17.0 m) in drill hole RC-26-176;
  • 1.40 g/t Au over 7.0 m (from 32.0 m to 39.0 m) and 7.03 g/t Au over 1.0 m (from 6.0 m to 7.0 m) in drill hole RC-26- 219; and
  • 1.61 g/t Au over 7.0 m (from 16.0 m to 23.0 m) in drill hole RC-26-227.

The Company expects to incorporate the results of the RC Infill Drill Program into a future updated Mineral Resource Estimate that is expected to be completed separately from the ongoing updated Feasibility Study. As the updated Feasibility Study is expected to be completed later in 2026, and the RC Infill Drill Program remains ongoing, results from the program will not be available for incorporation into the Mineral Resource Estimate supporting the updated Feasibility Study. 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.

The cross sections correspond to the section lines shown in Figure 2. Areas along the section lines without drill holes represent portions of the deposit that are not currently accessible to drilling due to historical workings or surface access constraints. These areas are expected to be drilled in the future when access becomes accessible.

QA/QC

The Company has implemented a quality assurance and quality control (“QA/QC”) program to ensure that sampling and analytical procedures for exploration work are conducted in accordance with CIM Exploration Best Practice Guidelines. The program includes the regular insertion of certified reference materials, blanks, and laboratory prepared sample duplicates into the sample analysis stream. Laboratory QA/QC procedures also include internal standards, blanks, and repeat analyses. QA/QC results are reviewed on an ongoing basis by the Company’s technical team, and any failures or anomalous results are investigated, with re-analysis requested where appropriate.

Reverse circulation drill samples were collected at nominal one-metre intervals using a cyclone and riffle/rotary splitter system. All RC samples were weighed and sample weight variability and recovery checked throughout the drill program to ensure sample quality. A 2.5 kg sample weight was targeted throughout the program with an average recovery of ~85%. A geologist is always present at the rig to monitor drilling and sampling procedures. Representative split samples were placed in labelled sample bags, sealed, and transported under chain-of-custody procedures to ALS Canada Ltd. (“ALS”) in Moncton, New Brunswick. ALS is independent of the Company. Samples submitted for gold analysis by PhotonAssay™ were crushed to approximately 70% passing 2 mm, after which a representative 500 g split was collected using a riffle splitter and transferred into jars for analysis at ALS in Thunder Bay, Ontario.

PhotonAssay™ uses high-energy X-rays to determine gold content from a large sample aliquot, typically 500 g of crushed material. The method is non-destructive and is particularly suited to gold systems where larger sample aliquots may improve representativity. For samples returning greater than 350 g/t Gold, an additional PhotonAssay™ analysis is completed using higher-grade standards. Due to the non-destructive nature of the PhotonAssay™ analysis, standard 30 g fire assay check analyses are conducted routinely on the jarred material to compare results with the PhotonAssay™ data and monitor analytical performance.

Selected samples analyzed via PhotonAssay™ will be re-analyzed via total pulp metallics. For the total pulp metallics analysis, the entire sample is crushed to -10mesh and pulverized to 95% -150mesh. The total sample is then weighed and screened to 150mesh. The +150mesh fraction is fire assayed for Au, and a 30 g subsample of the -150mesh fraction analyzed via fire assay. A weighted average gold grade is calculated for the final reportable gold grade. Total pulp metallics assays for drill holes sited within this press release may be updated in a future news release.
