The Company’s additions to the Warintza asset in the year ended December 31,2025 are provided below (2024: $nil).

La Verde is situated in the Sierra Madre del Sur west of Mexico City in Michoacán State, Mexico and consists of the Unificación Santa Maria claim. The project is held 60% by the Company and 40% by a subsidiary of Teck Resources Limited (“Teck”). The joint venture agreement governing the operation and funding of La Verde was formalized effective February 28, 2015 (the “Agreement”). The Agreement provides that Solaris is the operator of the project. The Agreement further provides for dilution of either parties’ ownership should funding not be provided in accordance with their respective participating interests. La Verde is subject to a 0.5% net smelter royalty held by Minera CIMA, S.A. de C.V.

As of December 31, 2025 the lack of historical capital expenditure on the La Verde asset was identified as an indicator of impairment. Consequently, management performed an impairment test to determine the asset’s recoverable amount. An independent valuation was commissioned, utilizing market and cost approaches, specifically the comparable in-situ resource multiple method. The impairment assessment determined that the asset’s recoverable amount exceeded its carrying amount; therefore, no impairment loss was recognised.

The Company owns a 100% interest in Warintza. Warintza is located in southeastern Ecuador in the province of Morona Santiago, Canton Limon Indanza.

Solaris has entered into an option agreement to acquire up to a 100% interest in 10 new explorations concessions from the Ecuadorian state-owned mining company, Empresa Nacional Minera (“ENAMI EP”).

The Company made an upfront payment to ENAMI EP of $250 on May 10, 2024 and, in order to exercise the option to acquire one or more of the 10 concessions, the Company is required to (i) incur exploration expenditures of $25,000 during the exploration phase of the concessions, as defined by the Ecuadorian Mining Law and (ii) pay the exercise price, the amount of which will be determined for each of the concessions that the Company elects to acquire by independent experts at the time of exercise. The term of the option agreement ends at the earlier of (i) the execution of the specific commercial agreement for each concession, which will stipulate a new term or (ii) four years from May 7, 2024 and is renewable with the agreement of the parties.
