Headwater Gold Mobilizes Geophysical Surveys at Jake Creek

Project, Nevada and Provides Update on Exploration Activities

Vancouver, British Columbia, February 18, 2026: Headwater Gold Inc. (CSE: HWG) (OTCQX:

HWAUF) (the "Company" or "Headwater") is pleased to announce that CSAMT resistivity and

ground gravity geophysical surveys are underway at its 100% -owned Jake Creek project in

Nevada. The surveys are fully funded pursuant to the earn -in agreement with OceanaGold

Corporation (“OceanaGold”) (TSX: OGC, OTCQX: OCANF) (“Oceana”) announced on October

15, 2025.

Highlights:

• CSAMT and Gravity Geophysical Surveys Underway: 12.5 line-kilometre CSAMT and

600-station gravity survey designed to define structural controls and prioritize drill targets.

• New Surface Vein Discovery: Detailed mapping identified a new zone of outcropping

high-level epithermal quartz veining (“Pete’s Vein”) in the northern portion of the project.

• Soil Sampling and Geological Mapping Completed: 500-sample soil survey and

comprehensive geologic mapping have significantly refined the structural and stratigraphic

framework of the project.

• Drilling Planned for Summer 2026: An initial drill program is currently scheduled for

early summer 2026. The ongoing geophysical surveys will inform the final target areas

and program scope.

Caleb Stroup, President and CEO of the Company, states: “Historic drilling at Jake Creek

confirmed the presence of blind gold mineralization at moderate depth, including 11.3 g/t Au over

1.52 metres within a broader 45.72 metres grading 0.96 g/t Au in hole JC -005. What has been

missing is a clear understanding of the structural framework controlling that mineralization, which

is a key reason the system was never adequately followed up. Our current program of detailed

mapping, relogging, soils and rock sample geochemistry and modern geophysics is focused on

defining the fault architecture and district-scale fluid pathways responsible for mineralization. As

we refine this structural and geological model, we are generating increasingly well -constrained,

high-quality drill targets in advance of an initial drill program, funded by OceanaGold and

scheduled for early summer 2026.”

Jake Creek Geophysical Surveys:

Headwater has engaged geophysical service providers to perform CSAMT and gravity surveys at

Jake Creek including:

CSAMT: A controlled -source audio -frequency magnetotelluric (“CSAMT”) resistivity survey

totaling 12.5 line-kilometres (“line-km”) on five parallel lines that align with soil survey lines (Figure

1) and one perpendicular (northwesterly) line. The main array is designed orthogonal to the

primary set of northwest-oriented faults that align with the margin of the Northern Nevada Rift and

are interpreted by Headwater geologists to be the main control of epithermal mineralization. The

2

northwest-oriented CSAMT line is designed to pinpoint the location of a significant northeast-

striking fault that bounds a modern basin at the southern portion of the Property . S tructural

intersections between northwest and northeast -striking faults are important centres of

mineralization at the nearby Hecla Midas and Hollister mines.

Gravity: A ground gravity survey consisting of 600 stations on a 200-metre-spaced grid with 400

metre spacing along the margins (total survey footprint of 28 km2) to cover the entire Project area.

Headwater geologic mapping demonstrates the Property is comprised of a series of fault blocks

at the edge of the Northern Nevada Rift. Detailed gravity data will permit further refinement of

property-wide structural tren ds and identify fault segments that have potential to serve as

mineralized epithermal feeder structures.

2025 Exploration Program Update

The 2025 exploration program at Jake Creek consisted of detailed geologic mapping, relogging

of historic reverse circulation (“RC”) drill chips, rock chip sampling and a 500 -sample soil

geochemistry survey. The objective of this work was to refine the geol ogical model, better

understand structural controls and prioritize areas for follow -up with geophysical surveys and

drilling.

bladed quartz-after-calcite epithermal boiling texture. Right: Rhyolite flow with chalcedonic quartz crackle

breccia and highly anomalous pathfinder element geochemistry (579 ppm As, 167 ppm Mo, 50 ppm Sb,

1% Mn)

Mapping and RC chip relogging confirm that Jake Creek is situated along the western margin of

the Northern Nevada Rift and is characterized by west -dipping fault blocks that control volcanic

stratigraphy and mineralization. The work has improved understanding of the Tertiary

unconformity and its relationship to epithermal mineralization intersected in historic drilling.

Reconnaissance mapping in the northern portion of the project identified a linear array of

outcropping chalcedonic quartz -opal veins and crackle breccias hosted within flow -banded

rhyolite (Figure 2) . These veins exhibit classic high -level epithermal textures, including local

bladed quartz -after-calcite and are associated with strongly anomalous arsenic, mercury,

antimony, molybdenum, tungsten and manganese geochemistry. This represents the first

significant outcropping veining identified at Jake Creek.

The soil survey, completed on 50-metre-spaced samples along broadly spaced orientation lines,

highlights coherent pathfinder element anomalies that align with mapped northwest -trending

structures and areas of silicification and clay alteration. These resul ts provide important vectors

for drill targeting, particularly where geochemical anomalies coincide with mapped or inferred

structures, such as in the area of Pete’s Vein in the northern project area.

About the Jake Creek project:

The Jake Creek project is 100% owned by Headwater and consists of 189 unpatented lode mining

claims on BLM land in Humboldt County, Nevada, located 65 km northwest of Winnemucca and

8 km east of the Nevada Gold Mines’ Turquoise Ridge Mine Complex. A portion of the project is

subject to a 1% NSR, half of which can be purchased for $1,000,000 at any time. For further

information see Headwater news release - March 3, 2025.

The project covers 3,700 acres on the western margin of the Northern Nevada Rift , a north-

northwest trending structural corridor known for hosting significant precious metal mineralization

including Hecla’s past-producing Midas Mine and Hollister Mine.

weights for weighted sum model: Au 2, Ag 1, As 1, Mo 1, Tl 1, Cs 1, W 1 and Mn 1.

The geology is dominated by mid -Miocene bimodal volcanic rocks, including rhyolite to dacite

flows and welded tuffs, unconformably overlying Paleozoic sedimentary rocks at depths of 50 to

300 metres. North-northwest and east-northeast trending faults, likely related to the rift’s 14 -16

Ma extension, dissect the property and may control mineralization. Historic drilling by Evolving

Gold Corp. in 2010 and 2011 (13 RC holes total) intersected widespread epithermal mineralization

at the Tertiary unconformity, with notable intercepts1 such as 11.3 g/t Au over 1.52 m within 45.72

m grading 0.96 g/t Au from 210.3 m in hole JC-005 (see Headwater news release - March 3,

2025). This mineralization, associated with silicification, clay alteration and banded quartz

veining, suggests a robust low-sulfidation epithermal system with potential for high-grade feeder

zones at depth or along strike.
