The Company is advised that such affiliates, controlled directly or indirectly by Mr. Elsztain (i) acquired the above mentioned securities for investment purposes, (ii) intend on reviewing investments in the Company’s securities on a continuing basis and such holdings may be increased or decreased in the future, the whole in the context of the Investor Rights Agreement, and (iii) may in the future acquire or dispose of Common Shares through the open market, privately or otherwise, as circumstances or market conditions dictate.

A copy of the Early Warning Report filed by Mr. Elsztain may be obtained from the Company’s SEDAR profile.

The purchase of the 6,250,000 Elsztain Units constitutes a “related party transaction” for the purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions. The Company is exempt from the requirements to obtain a formal valuation or minority shareholder approval in reliance on sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of the securities issued to the Insiders nor the fair market value of the consideration for the securities issued to the Insiders exceeds 25% of the Company’s market capitalization as calculated in accordance with MI 61-101. The Company did not file a material change report containing all of the disclosure required by MI 61-101 more than 21 days before the expected closing date of the offerings as the aforementioned insider participation had not been confirmed at that time and the Company wished to close the offerings as expeditiously as possible.

About the El Quevar Project

The El Quevar Project is located in Salta, Argentina and spans an area of 57,000 hectares. The property remains underexplored with less than 3% of the area covered with comprehensive exploration work. The property boasts exceptional infrastructure with over 60 km of internal roads, a fully owned, fully operational camp for 100 workers with multiple support buildings, and a railroad, gas pipeline and service road just 3 km from camp, while a high–voltage transmission line lies approximately 20 km from the exploration area. The robust infrastructure associated with the project provides a cost-effective platform to de–risk and accelerate future drilling and development.

The foundational Mineral Resource Estimate of the Yaxtché deposit boasts an indicated mineral resource of 45.3 million ounces of silver from 2.93 million tonnes grading 482 g/t Ag, and an inferred resource of 4.1 million ounces from 0.31 million tonnes grading 417 g/t Ag (1). The mineral resource area remains open at depth and in multiple directions, particularly to the southeast and northwest. One of the objectives of the ongoing 2025 Winter Drilling Program is to specifically target and expand these high-grade Yaxtché zones.

The mineralization at the Yaxtché deposit is defined as a silver rich, high to intermediate-sulphidation epithermal system with associated gold. Mineralization is controlled by NW-SE and NE-SW fault structures and is mainly hosted in brecciated zones and dacite domes. Silver minerals at Yaxtché consist of complex silver sulphides, sulphosalts and native silver. These minerals are found within silicified breccias, commonly appearing as veinlets, stockworks, disseminations, and breccia fillings.
