LEASES
The Company’s operating leases consist primarily of leases for office space, vehicles, and plant and mining equipment. These leases have a range of terms between three years to thirteen years with renewal terms included in the contracts. Some are automatic renewals, and some are at the option of the Company. There are no restrictions placed upon the lessee by entering into these leases.
The Company's principal finance lease relates to its right to use the oxygen plant supplied by Air Liquide Gaz Sanayi ve Ticaret A.S. (the “Air Liquide Plant”) at Çöpler. The Air Liquide Plant is used for the production, transportation and delivery of oxygen and liquid oxygen to support mining operations at Çöpler. Under the terms of the Air Liquide Plant lease, the Company pays variable monthly lease payments that depend on an index. In addition, the Company is subject to variable payments based on consumption and use which have been accounted for as non-lease components and included in Cost of sales. The Air Liquide Plant lease contains a non-cancellable period of 15 years ending in 2033 with options to extend for consecutive 2-year periods. The lease term used in the measurement of the Company's lease liability and right-of-use asset includes four consecutive 2-year extension periods ending in 2038 for which the Company is reasonably certain to exercise its option in line with the Çöpler LOM.

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
