 Firm commitment of US$2,500,000:   OceanaGold to fund a minimum commitment of US$2,500,000 in exploration   expenditures across three Projects within the first two years of the   Agreement;
 
Up to US$65,000,000 in staged earn-in expenditures:   OceanaGold may elect to earn up to a 65% interest in each Project by   funding exploration expenditures of US$25,000,000 on each of TJ and Jake   Creek and US$15,000,000 on Hot Creek;
 
OceanaGold may elect to earn an additional 10% by completing a PFS:   By completing a Pre-Feasibility Study (“PFS”) on each project   OceanaGold may earn an additional 10% in each Project (for a total of   75%) and grant Headwater a 1% NSR royalty upon completion of the PFS;
 
10% Management Fee: Under the partnership, Headwater will be the initial operator of the Projects and will receive a 10% management fee; and
 
Commencement of drilling on the TJ project: Drill mobilization to the TJ project has begun following the execution of the Agreement.
 
 
 Caleb Stroup, Headwater’s President and CEO, states: “We   are very excited to have executed the Definitive Agreement with   OceanaGold, a strong technical and financial collaborator. The stage is   now set for a series of exploration programs on all three of these   projects in 2025. Mobilization for the TJ drilling program has commenced   and we are eagerly anticipating the kickoff of this high-priority  drill  test. TJ is interpreted to represent a robust, fully preserved   epithermal system with multiple high-quality targets identified during   our work last year and the partner-funded drilling this year is designed   to unlock the project’s full potential.”

 About the TJ Project:
 
 The   TJ project is located on Bureau of Land Management (“BLM”) 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 in the core of the   property. Epithermal alteration is localized along a series of steeply   inclined faults that bound a graben filled with Miocene-age  sedimentary  rocks.
 
 Limited  historic exploration on the property  included shallow Reverse  Circulation (“RC”) drilling that confirmed  the presence of a broad zone  of high-level epithermal alteration. The  Company completed an initial  round of scout drilling in 2024 which  confirmed the project has  potential for high-grade epithermal  vein-style mineralization at depth ( Headwater news release - January 16, 2025).   A follow-up core drilling program is being planned with the objective   of testing prospective epithermal structures identified during the 2024   program at depth.
 
 The TJ project is subject to  an underlying  exploration lease and option to purchase agreement under  which the  Company may acquire a 100% interest in the project for  US$1,500,000  inclusive of annual minimum payments. A portion of the  project is  subject to NSR royalties ranging from 1.5% to 2.5% with  Headwater  retaining the right to buy-down 80% of the NSR.
 
 About the Jake Creek Project:
 
 The   Jake Creek project is 100% owned 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. Historic drilling by Evolving Gold Corp.   in 2010 and 2011 (13 RC holes) 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 in   hole JC-005. 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. A portion of the project is subject to a 1% NSR, half  of  which can be purchased for US$1,000,000 at any time. For further   information see  Headwater news release - March 3, 2025.
 
 About the Hot Creek Project:
 
 The   Hot Creek project is 100% owned and royalty-free and consists of 52   unpatented mining claims staked by Headwater in the Tuscarora District   in Nevada. The project hosts a widespread zone of silica flooding in   Tertiary sediments in the immediate hanging wall of a silicified range   front fault. Historical shallow drilling1 results include  grades up to  1.04 g/t Au over 12.2 m and 0.34 g/t Au over 117.3 m along a  range  front fault. The majority of the historic drill holes at Hot  Creek were  relatively shallow and did not adequately test for the  presence of  high-grade feeders at depth along the range front fault or  subsidiary  structures. Future exploration at Hot Creek will focus on  refining the  geological model, identifying new high-potential targets  and conducting  additional geological mapping and surface sampling. For  further  information see  Headwater news release - September 4, 2024.
