(CSE: HWG) (OTCQX: HWAUF) (the “Company” or “Headwater”) is pleased to announce results from the recent core drilling program at its TJ Project in Elko County, Nevada. The program was fully funded by OceanaGold Corporation (“OceanaGold”) (TSX: OGC, NYSE: OGC) pursuant to the earn-in agreement announced October 15, 2025. Highlights: - Highest gold grades to date:Core drilling returned grades up to 5.61 grams per tonne gold (“g/t Au”), confirming the presence of a high-grade epithermal vein system below the surface sinter. - Large, dynamic hydrothermal system confirmed: Drilling intersected 100 m thick hydrothermal breccia intervals, syn-mineral intrusions and multiple phases of epithermal veining across more than 500 metres of strike length.Banded and lattice-bladed quartz veins, together with stacked sinter horizons intercalated with sedimentary units, support the thesis of a long-lived, productive epithermal system. - System open and expanding:Drilling has tested only a small portion of the system, but mineralization remains open at depth and along strike. The Company recently expanded the TJ land position by 88% (to 1,990 hectares) to cover the prospective northern continuation of the TJ graben. - Next phase underway: Gravity and CSAMT geophysical surveys as well as geologic mapping and surface sampling programs are planned within the newly expanded land position to define the lateral extent of the alteration cell and prioritize follow-up drilling. Caleb Stroup, President and CEO of the Company, states:“The 2025 drilling program at TJ represents a step change in our understanding of the project. What began as a surface sinter anomaly has now been confirmed as a large, structurally controlled hydrothermal system with significant vertical and lateral extent. Core drilling has intersected hydrothermal breccias, multiple phases of veining with clear boiling textures and the highest gold grades seen on the project to date, all of which point to a productive epithermal system at depth. Importantly, we have only tested a small portion of the strike extent of the system beneath the main sinter and the presence of stacked sinter horizons and extensive alteration at depth indicates that it extends well beyond the current drill area. Expanding the land position and completing district-scale geophysics are the critical next steps to define the full footprint of the system before returning with a follow-up drill program.” [](https://www.thenewswire.com/data/tnw/clients/img/3cc06b0c0ec85b7ca30edd0622570cab.png) Click Image To View Full Size Figure []()1: Plan map of TJ project area showing recent claim expansion.

Cross section A–A’ corresponds to the interpreted geology cross section shown in Figure 2. 2025 TJ Drill Program: Headwater completed approximately 1,350 metres of core drilling over five holes during the 2025 program (Figure 1), fully funded by OceanaGold through Stage 1 of the earn-in agreement. Four holes targeted the East Sinter fault and associated structures beneath the main sinter exposure. An additional hole targeted the Jackpot fault, characterized by a >2 km-long break in CSAMT resistivity (Figure 1). The final hole of the program, designed as a step-out approximately 300 metres to the south, was suspended prior to reaching target depth due to winter weather conditions and has been cased for future re-entry. Drilling was designed as a follow-up on the Company’s 2024 RC scout drilling campaign which confirmed the presence ofwidespread silicification and epithermal veining as well as broad intervals of anomalous gold mineralization in the hanging wall of the East Sinter fault. However, this initial programdid not test sufficient depths where potential high-grade mineralization is typically developed (see news releases dated December 20, 2024 and January 16, 2025).
