WD-26-09 was collared in the southwest at the edge of our drill pattern (oriented at 340°, angled 50°

below horizontal, to a depth of 200 meters) and successfully intersected a high-grade VMS Lens. We

intersected a thick massive sulphide lens carrying copper, lead, zinc, silver and gold, with visible

chalcopyrite and bornite in the core. Within the broader zone, a 16.50m section averaged 4.03% Cu-Eq,

and a 6.50m zone returned 5.22% Cu-Eq. A Silver Zone of 21.75m returned 31.72 g/t Ag (1.02 oz/t Ag),

with the peak sample reaching 58 g/t Silver. A Gold Zone of 20.20m returned 0.67 g/t Au including 11.00

m of 0.87 g/t Au. Zinc averaged 2.02% over 22.50m, including 4.82% over 5.75m and 8.09% over

3.00m, with a peak sample of 11.40% Zinc. All intersections are a true width.

Gary Lohman, P.Geo., VP Exploration, Director stated,

"Definitely nice to return to the VMS section previously identified in the southwest. Drilled at a

steeper angle than previous holes in the vicinity, this assists in expanding the deposit footprint. In

addition to Cu, the assays also indicate substantial Au and Ag present in this portion of the system.

Intersecting five payable metals over this width and seeing copper strengthen toward the base of

the zone is exactly what we want to see at this stage. Additional drill holes are planned for this

western portion of the Wedge, where we believe there is meaningful room to expand the deposit."

Shaded rows are the peak sample for each metal. Copper Equivalent (CuEq) combines all five metals

into one comparable grade, calculated using August 11, 2026, Bloomberg pricing: US$6.63/lb Cu,

US$0.84/lb Pb, US$1.72/lb Zn, US$65.10/oz Ag, US$4,443.90/oz Au, with a uniform 95% metallurgical

recovery assumed for all metals; since it is unclear which metals will be the principal products, assuming

differing recoveries by metal is premature at this stage.

Patrick J Cruickshank, MBA, CEO & Director stated,

"This was a very strong polymetallic VMS Hole, with a large Lens Zone. As you can see in the

itemized Sample Results Table, there is multiple high grade Copper, Silver and Gold zones,

confirming a multi-dimensional deposit at the Wedge. Each one of these mineral intercepts would

be a success on their own accord, but to combine them all in one hole shows the strength of this

Lens and is spectacular start to our results season. These results will be included in our Live 3D

Modelling headed by Mike Dufresne, President of Apex Geoscience & our Technical Team to

move towards an updated 43-101 and an MRE objective. We are extremely pleased by these

results and look forward to releasing our next set of results from ALS Global in Moncton.

Unfortunately, we have no control over the order of our results coming back from the Labs."

Stock Options Award

The Company has also granted an aggregate of 250,000 incentive stock options to a consultant,

pursuant to the Company's stock option plan. The options are exercisable at a price of $0.08 per share

for a period of 5 years from the date of grant and vest immediately.

Analysis, QAQC and Qualified Person

All samples were submitted to ALS Global in Moncton, an independent commercial laboratory, for

preparation and assaying (ME-ICP61a four-acid digestion with ICP-AES; Au by fire assay Au-AA23 with

AA finish; overlimit Au by gravimetric analysis and overlimit base metals by OG62). ALS runs its own

QA/QC protocols including coarse and pulp duplicates. Nine Mile's QAQC program includes regular

insertion of CRM standards, duplicates and blanks with a stringent review of all results; QAQC and data

validation were performed and no material errors were observed. Technical information in this news

release has been prepared in accordance with NI 43-101 and reviewed and approved by Gary Lohman,

B.Sc., P.Geo., VP Exploration and Director, the Company's Qualified Person, who is not independent of

the Company.

Copper Equivalent (Cu-Eq) for the drill hole samples is calculated based on August 11, 2026 Bloomberg

Pricing, pricing: US$ 6.63/lb Cu, US$ 0.84/lb Pb, US$ 1.72/lb Zn, US$ 65.10/oz Ag, and US$

4,443.90/oz Au, with 95% metallurgical recoveries assumed for all metals. Since it is unclear which

metals will be the principal products, assuming different recoveries is premature at this stage. Therefore,

a 95% recovery rate is justified.

About Nine Mile Metals Ltd.

Nine Mile Metals Ltd. is a Canadian public mineral exploration company focused on Critical Mineral

VMS (Cu, Pb, Zn, Ag and Au) exploration in the world-famous Bathurst Mining Camp, New Brunswick.

The Company is exploring four VMS projects: Wedge, Nine Mile Brook, California Lake, and Canoe

Landing Lake (East - West), positioning for the boom in AI data centers, EV and green technologies

requiring copper, silver, lead and zinc, with a hedge with gold.
