KEY HIGHLIGHTS:

• Homerun can use the surface rights as collateral in project financing, independently secure permits and licenses, and is protected against changes in land ownership.
• The Municipality of Belmonte provides commitment of funding allocation for paving of approx. 5km of road connecting Santa Maria Eterna to BR-101, the main federal highway in the region in support of Homerun’s project sites.

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) (‘Homerun’ or the ‘Company’) is pleased to announce that it has signed a definitive surface rights agreement (the ‘Agreement’) over the CENTRO INDUSTRIAL SÃO JOSÉ DA SILICA, located in the Municipality of Belmonte, Bahia, Brazil, in the district of Santa Maria Eterna (‘SME’), for the installation of Homerun’s silica processing plant and solar glass manufacturing facility. The Agreement covers a total area of 64 hectares and is directly contiguous to both BA982 and the Company’s SME Silica resources in the SME Silica Sand District.

The Agreement grants Actual Surface Rights (Direito Real de Superfície / Surface Rights) to Homerun under the terms of Articles 1,369 to 1,377 of the Brazilian Civil Code, and ensures irrevocable transfer of those Surface Rights over the property to Homerun, and once registered on the land’s public deed, ensures total legal security in favor of Homerun, regardless of any eventual transition of ownership of the underlying property by the landowners.

The specific purpose for the granting of those Surface Rights is for the construction of an industrial complex for the manufacture of processed silica and solar glass and correlated products, storage, logistics, research and development, commercial and supporting activities, and any other activity needed for the proper development of Homerun’s industrial projects.

This Agreement replaces the planned donation of the same land previously authorized by the Municipality of Belmonte. This replacement relieves Homerun of the obligations under the MoU, eliminating any risk of having to return of the land to the Municipality, if those Homerun obligations were not met.

In addition to this agreement, Homerun has received a letter of support from the Municipality of Belmonte represented by Mr. Iêdo José Menezes Elias, reaffirming its commitment to support the development of Homerun Resources Inc.’s silica sand project, located in the district of Santa Maria Eterna. As part of this commitment, the Municipality will allocate up to USD $400,000 toward infrastructure improvements related to the project including the completion of the executive project for the paving of approximately 5km of road connecting Santa Maria Eterna to BR-101, the main federal highway in the region. This initiative is part of a broader program led by the Bahia State Secretariat of Infrastructure (SEINFRA).

Brian Leeners, CEO of Homerun stated, ‘We wish to thank the parties to the original MoU and the landowner for helping to get this key deliverable completed in a timely manner before the pending receipt of our Bankable Feasibility Study and Financing of the Industrial Plants. We continue to work with the parties to the original MoU to facilitate the further items under the MoU, including the utilities and the Municipality of Belmonte’s financial support toward the development of infrastructure. The signing of this new Agreement aligns with the execution of the Company’s strategy to develop and construct Homerun’s Silica Processing and Solar Glass Manufacturing facilities, in the Municipality of Belmonte, ensuring the establishment of the entire silica value chain, from resource to extraction to processing to high value-added final product at the Santa Maria Eterna site, maximizing both the socioeconomic and environmental benefits for the people of the State of Bahia.’

The preliminary area of Homerun’s Surface Rights is shown in Figure 1 and will be reviewed and can be modified if needed in an amended common agreement between the parties. Homerun has full access to the area immediately.

The Agreement is valid for 99 years from the date of the registration in the land’s deed. This term will be automatically renewed for an additional 99 years, unless either of the parties manifest otherwise 5 years before the original expiration date.

The compensation payments will begin in 2027, with one fixed payment of R$ 60,000 due on June 30, 2027. Starting in January of 2028, there will be monthly payments of R$ 50,000 subject to the caveat that if no plant construction has started by January 2028 for reasons beyond Homerun’s control, the payment will be reduced by fifty percent until construction starts. The amounts will be updated annually using the IPCA index (inflation adjustment).

Among the Surface Rights secured through this Agreement, Homerun is entitled to offer the Surface Rights as collateral in financing and Homerun can obtain licenses and permits without any input or interference by or from the landowners. Homerun also becomes responsible for all costs, including taxes, affecting the land. In the situation where the landowners decide to sell, lease, exchange, donate, or perform any transaction with the property, Homerun has the right of first refusal.

As the underground sampling was limited to the extent of the mine workings, detailed drilling is necessary to determine the ultimate size, shape and grade of the mineralized zones.  Consequently, Pinnacle’s geological team has compiled the results and created 3D models of the Dos de Mayo vein and the exposed mineralization in the 3 mines (see Figure 3 below) in order to create a program of systematic drilling whereby the vein structure will be tested every 12.5 metres along strike and vertically.  As the holes will be collared either in or immediately adjacent to the vein structure, holes will be relatively short, in the range of 20-25 metres in length.  At present, it is anticipated that the entire program will comprise approximately 2,600 metres in 112 holes and take about 6 weeks to complete.

‘The underground drilling will be a significant step in the development of the Potrero Project ,’ stated Robert Archer, Pinnacle’s President & CEO.  ‘It is not common that the first drill program on a new project is underground.  However, we are fortunate to have good access to at least some of the mineralization through the historic mine workings and this detailed program will essentially be delineation drilling rather than exploration. With the results of this program, we will gain a very good understanding of the principal mineralized zones such that we can begin putting together a preliminary mine plan .  Follow-on surface drilling can then test the areas between the mine workings in addition to less developed veins like El Capulin and La Estrella that are being sampled for the first time.’

A certain amount of development work will be required in the historic workings to create enough room for the drill setups and make sure that the drillers will have a safe working environment.  This work will begin early in the New Year and will take about one month to complete, with drilling to follow as soon as possible.

QA/QC

The technical results contained in this news release have been reported in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (‘NI 43-101’).  Pinnacle has implemented industry standard practices for sample preparation, security and analysis given the stage of the Project.  This has included common industry QA/QC procedures to monitor the quality of the assay database, including inserting certified reference material samples and blank samples into sample batches on a predetermined frequency basis.

Systematic chip channel sampling was completed across exposed mineralized structures using a hammer and maul.  The protocol for sample lengths established that they were not longer than two metres or shorter than 0.3 metres.  The veins tend to be steeply dipping to vertical, and so these samples are reasonably close to representing the true widths of the structures.  Samples were collected along the structural strike or oblique to the main structural trend.  Grab samples, by their nature, are only considered as indicative of local mineralization and should not be considered as representative.

All samples were bagged in pre-numbered plastic bags; each bag had a numbered tag inside and were tied off with adhesive tape and then bulk bagged in rice bags in batches not to exceed 40 kg.  They were then numbered, and batch bags were tied off with plastic ties and delivered directly to the SGS laboratory facility in Durango, Mexico for preparation and analysis.  The lab is accredited to ISO/IEC 17025:2017.  All Samples were delivered in person by the contract geologist who conducted the sampling under the supervision of the QP.

SGS sample preparation code G_PRP89 including weight determination, crushing, drying, splitting, and pulverizing was used following industry best practices where all samples were crushed to 75% less than 2 mm, riffle split off 250 g, pulverized split to >85% passing 75 microns (μm).  All samples were analyzed for gold using code GA_FAA30V5 with a Fire Assay determination on 30g samples with an Atomic Absorption Spectography finish.  An ICP-OES analysis package (Inductively Coupled Plasma – Optical Emission Spectrometry) including 33 elements and 4-acid digestion was performed (code GE_ICP40Q12) to determine Ag, Zn, Pb, Cu and other elements.

Qualified Person

Mr. Jorge Ortega, P. Geo, a Qualified Person as defined by National Instrument 43-101, and the author of the NI 43-101 Technical Report for the Potrero Project, has reviewed, verified and approved for disclosure the technical information contained in this news release.

About the Potrero Property

El Potrero is located in the prolific Sierra Madre Occidental of western Mexico and lies within 35 kilometres of four operating mines, including the 4,000 tonnes per day (tpd) Ciénega Mine (Fresnillo), the 1,000 tpd Tahuehueto Mine (Luca Mining) and the 250 tpd Topia Mine (Guanajuato Silver).

High-grade gold-silver mineralization occurs in a low sulphidation epithermal breccia vein system hosted within andesites of the Lower Volcanic Series and has three historic mines along a 500 metre strike length.  The property has been in private hands for almost 40 years and has never been systematically explored by modern methods, leaving significant exploration potential.

A previously operational 100 tpd plant on site can be refurbished / rebuilt and historic underground mine workings rehabilitated at relatively low cost in order to achieve near-term production once permits are in place. The property is road accessible with a power line within three kilometres.

Pinnacle will earn an initial 50% interest immediately upon commencing production.  The goal would then be to generate sufficient cash flow with which to further develop the project and increase the Company’s ownership to 100% subject to a 2% NSR.  If successful, this approach would be less dilutive for shareholders than relying on the equity markets to finance the growth of the Company.

About Pinnacle Silver and Gold Corp.

Pinnacle is focused on the development of precious metals projects in the Americas.  The high-grade Potrero gold-silver project in Mexico’s Sierra Madre Belt hosts an underexplored low-sulphidation epithermal vein system and provides the potential for near-term production . In the prolific Red Lake District of northwestern Ontario, the Company owns a 100% interest in the past-producing, high-grade Argosy Gold Mine and the adjacent North Birch Project with an eight-kilometre-long target horizon . With a seasoned, highly successful management team and quality projects, Pinnacle Silver and Gold is committed to building long -term , sustainable value for shareholders.

GRANDE PRAIRIE, ALBERTA TheNewswire – December 15, 2025 – Angkor Resources Corp. (TSXV: ANK,OTC:ANKOF) (‘ANGKOR’ OR ‘THE COMPANY’) is pleased to announce that it has entered into a binding Letter of Intent (‘LOI’) with an arm’s length party (the ‘Purchaser’) to sell its 40% participating interest in the Evesham Macklin oil and gas lands (the ‘Assets’) in Saskatchewan at a sale price of $4,800,000. The sale of the Assets is anticipated to be completed on January 31, 2026 (the ‘Closing Date’).

The Assets were acquired by the Company through its wholly owned-subsidiary EnerCam Exploration Ltd. on December 12, 2023 and the Purchaser provided a loan (the ‘Loan’) to fund the acquisition. The outstanding amount of the Loan is $3,800,000.

CEO Delayne Weeks comments on the decision to sell the Assets, ‘This decision follows a full analysis over the greatest value increases for shareholders in the coming 24 months.  In our view, the greatest growth value of Angkor will be achieved on proving Cambodia’s first oil and gas discovery and the second will be on advancing assays and drilling on both gold and copper projects, either by ourselves or with strong partners.   Evesham is a great project, but it is a long-term multi-well field which requires more investment capital for water injection and ongoing capital upgrades.  Therefore, we will take the net sale proceeds from the sale of the Assets and apply the funds directly to packaging the oil and mineral projects in Cambodia for a sale or merger opportunity and other administrative operations. ‘

Transaction Summary

The terms of the LOI provide that the purchase price shall be satisfied by the Purchaser under the following payment terms: (a) a $250,000 non-refundable deposit is payable on December 31, 2025 after expiry of the Purchaser’s due diligence condition; (b) a payment of $375,000 is payable on the Closing Date; (c) the balance of the Loan will be applied to the purchase price on the Closing Date; and (d) a final payment of $375,000 subject to adjustment is payable on March 1, 2026. The terms of the LOI also provided that all profit entitlements and operating and capital commitments under the Assets after October 1, 2025 shall accrue to the Purchaser.

Conditions to Closing

The parties intend to enter into a form of asset purchase and sale agreement which shall replace the LOI and shall contain customary commercial terms and closing conditions such as approval of the sale and transfer by the operator of the Assets, appropriate representations, warranties and indemnities of the parties, receipt of all applicable regulatory and shareholder approvals and approval of the stock exchange.

No finder’s fees were paid on the transaction.

Weeks continues, ‘The sale transaction will be achieved without any dilution of our stock and no commissions are payable;  we can use the net sale proceeds where we most need them.   We are also blessed to have developed strong relations with exemplary oil operators and developers at Evesham, who remain great advisers and colleagues on oil and gas opportunities.’

The Company is completing the interpretation of the seismic program over four subbasins on Block VIII, Cambodia’s first onshore oil and gas license under exploration.   Multiple targets have been identified.   Geoscientists indicate the end of December to have a completed interpretation of the results with drill targets.

Weeks adds, ‘The processing of the seismic produced results beyond our expectations.  We have already concluded that instead of a single target, we have 3-5 drill targets and proving commercial hydrocarbons on any of those areas will add greater value to the Company.   As well, the recent announcement of the gold prospect CZ Gold, Angkor Resources IDENTIFIES GOLD PROSPECT ON ANDONG MEAS LICENSE, CAMBODIA – Angkor Resources Corp leads us to focus all our resources in Cambodia to formulate a robust, attractive platform with significant upside that mitigates risk for investors with diversity in Cambodia’s first oil and gas discovery and is backed up with gold and copper prospects across several mineral licenses.
