Solitario leases one facility, its Wheat Ridge, Colorado office, that has a term of more than one year. The WR Lease is classified as an operating lease and has a term of 23 months at March 31, 2024, with no renewal option. At March 31, 2024 and December 31, 2023, the right-of-use office lease asset for the WR Lease is classified as other long-term assets and the related liability as current and long-term operating lease liabilities in the condensed consolidated balance sheet. The amortization of right-of-use lease asset expense is recognized over the lease term, with variable lease payments recognized in the period those payments are incurred.

During the three months ended March 31, 2024 and 2023, cash lease payments of $11,000 and $11,000, respectively, were made on the WR Lease. During the three months ended March 31, 2024 and 2023, respectively, Solitario recognized $9,000 and $10,000, respectively, of non-cash amortization of right-of-use lease asset expense for the WR Lease included in general and administrative expense. These cash payments, less imputed interest for each period, reduced the related liability on the WR Lease. The discount rate within the WR Lease is not determinable and Solitario has applied a discount rate of 7% based upon Solitario’s estimate of its cost of capital to determine the asset and liability upon the extension of the WR lease during 2023.

The maturities of Solitario’s lease liability for its WR Lease are as follows at March 31, 2024:
