Following the draw on October 26, 2026, the total draw on the Teck Facility outstanding is US$10.0 million. The proceeds from the drawdown will be used to support working capital requirements and ongoing operational activities as the Company advances toward full commercial production.

Amounts drawn bear interest at 13.5% per annum from their funding date to June 30, 2027, and a rate equal 15.0% per annum thereafter, subject to automatic increases. Interest is calculated on a 360-day year and capitalized quarterly in arrears. Upon an event of default, default interest accrues at the applicable rate plus 3.0% per annum.
