Headwater Gold Announces Completion of Drilling Campaigns at

the Lodestar and TJ Projects, Nevada

Vancouver, British Columbia, February 23, 2026: Headwater Gold Inc. (CSE: HWG) (OTCQX:

HWAUF) (the "Company" or "Headwater") is pleased to announce the completion of drill programs

at the Lodestar and TJ projects located in Nevada, United States. Lodestar drilling was 100%

funded by Newmont Corporation (“Newmont”) (NYSE: NEM, ASX: NEM, PNGX: NEM) through

an earn-in agreement announced on May 9, 2023. TJ drilling was 100% funded by OceanaGold

Corporation (“OceanaGold”) (TSX: OGC, OTCQX: OCANF) pursuant to the earn-in agreement

announced on October 15, 2025.

Highlights:

• Lodestar Drilling: Approximately 2,950 metres were completed over four core holes and

five reverse circulation holes. All holes drilled in the Zodiac Sinter target area intersected

the modeled structural target or adjacent pervasive hydrothermal alteration.

• TJ Drilling: Approximately 1,350 metres of core drilling were completed over five holes in

two target areas. Drilling was suspended due to the onset of inclement winter weather. All

holes encountered hydrothermal breccias and veining within pervasive epithermal

alteration.

• All drill samples from both programs have been submitted for laboratory analysis. Final

assay results are expected over the coming weeks.

Caleb Stroup, President and CEO of the Company, states: “We are pleased to have successfully

completed both the Lodestar and TJ drill programs which began in Q4 2025 . At Lodestar, we

intersected the targeted structures and associated hydrothermal alteration and at TJ we confirmed

the scale and continuity of epithermal veining along the East Sinter fault system. While assays

are pending, the geological observations from both programs are encouraging. We look forward

to receiving and interpreting the analytic al results and will outline follow -up plans once the full

dataset has been evaluated.”

About the 2025 Lodestar Drill Program:

Headwater completed approximately 2,950 metres of drilling in four core holes and five reverse

circulation (“RC”) holes at the Lodestar project. The core drilling focused on the Zodiac Fault, a

northwest-striking structure hosted in Miocene volcanic rocks exposed over a 550-metre strike

length, with silica sinter and intensely altered hydrothermal breccias at surface. The RC drill was

used for exploratory drilling on multiple satellite targets defined by geologic mapping and

geophysics and step-out drilling along the Zodiac Fault. Exploratory holes confirmed a 600 metre

by 700 metre zone of pervasive illite-pyrite-silica epithermal alteration within Miocene volcanic

rocks extending north and east from the Zodiac Fault zone. This hydrothermal alteration zone is

open to north, south and east, where widely-spaced RC drilling intersected this alteration in each

hole, as shallow as 30 metres from surface and covered by pediment gravels or younger Miocene

2

andesite lava flows. Alteration studies and geochemical analysis of these drill holes will be used

as vectors to influence potential follow-up drill targeting within this large alteration footprint.

About the Lodestar Project:

The Lodestar project is located in the Aurora Mining District in the Walker Lane belt, west-central

Nevada, approximately 10 km north of Headwater’s Spring Peak project (also subject to an earn-

in agreement with Newmont) and adjacent to Hecla Mining Company’s past -producing Aurora

mine complex, which hosts existing infrastructure including a 600 ton per day mill, several

production water wells and high -voltage three-phase power. The project features a prominent

silicified and brecciated ridgeline capped by a silica sinter, similar to the sinter overlying the Disco

Zone at Spring Peak, where Headwater has previously intersected high-grade gold mineralization,

including 15.92 g/t Au over 2.38 m and 10.43 g/t Au over 2.01 m. Historic shallow drilling at

Lodestar encountered anomalous gold but did not test deeper feeder structures, leaving

exploration potential largely u ntested. Headwater holds an option to acquire a 100% undivided

interest in the Lodestar project from a private vendor, subject to retained royalties and Newmont’s

option to acquire up to 75% of the project following certain expenditures and delivery of a P re-

Feasibility Study within a designated time frame.

About the 2025 TJ Drill Program:

Headwater completed approximately 1,350 metres of core drilling over five holes at TJ prior to

the winter shutdown.

The East Sinter fault, identified in the Company’s first pass RC program in 2024, was the highest

priority and was intersected in three of the four holes designed to test the target. The last hole of

the program, designed as a ~300 metre southern step-out along the East Sinter fault, was paused

due to inclement weather prior to reaching target depth and cased for future re-entry.

Thick intervals of epithermal veining, fault gouge and silicified fault breccias were encountered in

the main structural target area of all three holes that intercepted the East Sinter fault. A silicified

hydrothermal breccia body, up to 60 metres thick, was also intercepted in the hanging wall of all

holes directed at the East Sinter fault and coincides with the highest epithermal veining intensity

and generally the thickest vein widths.

All holes encountered epithermal alteration and veining, confirming that the system extends over

at least the >500 -metre-long tested extent and remains open along strike . Multiple discrete

phases of epithermal alteration are evidenced by several overlapping vein, breccia and intrusive

relationships as well as an interpreted series of stacked silica sinters encountered in several

drillholes.

About the TJ Project:

The TJ project is located on Bureau of Land Management land in a relatively underexplored area

of northeastern Nevada, approximately 25 km southeast of the town of Jackpot. The project area

contains indications of a fully preserved epithermal system, including a thick and laterally

extensive accumulation of silica sinter. Epithermal alteration is localized along a series of steeply

inclined faults that bound a graben filled with Miocene-age sedimentary rocks.

3

Limited historic exploration on the property included shallow RC drilling that confirmed the

presence of a broad zone of high -level epithermal alteration. In 2024, Headwater completed an

initial round of scout drilling which confirmed the project has poten tial for high-grade epithermal

vein-style mineralization at depth (see news release dated January 16, 2025). The follow-up 2025

core drilling program tested prospective epithermal structures at depth that were identified during

the 2024 program.

Headwater holds an option to acquire a 100% undivided interest in the TJ project, subject to

retained royalties and subject to OceanaGold’s option to acquire up to 65% of the project following

certain expenditures and preparation of a Pre-Feasibility Study within a designated time frame.
