2. Mineral Properties

The following table details Solitario’s investment in Mineral Properties:

(in thousands)	June 30,		December 31,
	2024		2023
Exploration
Lik (Alaska – US)	$	15,611	$	15,611
Golden Crest (South Dakota – US)		1,078		1,035
Cat Creek (Colorado – US)		12		-
Total exploration mineral properties	$	16,701	$	16,646

During the three and six months ended June 30, 2024, Solitario added a new area to its existing Golden Crest Project, covering approximately 98 claims. The initial cost for staking and recording these claims of $43,000 was capitalized as mineral properties. In addition, during the three and six months ended June 30, 2024, Solitario acquired a new early-stage exploration project, the Cat Creek Project, and capitalized its initial lease acquisition cost of $12,000. Solitario did not add any new exploration properties or projects during the three and six months ended June 30, 2023.

All exploration costs on our exploration properties, none of which have proven and probable reserves, including any additional costs incurred for subsequent lease payments or exploration activities related to our projects, are expensed as incurred.

Asset Retirement Obligation

In connection with the acquisition of its interest in the Lik Project in 2017, Solitario recorded an asset retirement obligation of $125,000 for Solitario’s estimated reclamation cost of the existing disturbance at the Lik Project. This disturbance consists of an exploration camp including certain drill sites and access roads at the camp. The estimate was based upon estimated cash costs for reclamation as determined by the permitting bond required by the State of Alaska for which Solitario has purchased a reclamation bond insurance policy in the event Solitario or its 50% joint venture partner, Teck, do not complete required reclamation.

Solitario has not applied a discount rate to the recorded asset retirement obligation as the estimated time frame for reclamation is not currently known, as reclamation is not expected to occur until the end of the Lik Project life, which would follow future development and operations, the start of which cannot be estimated or assured at this time. Additionally, no depreciation will be recorded on the related asset for the asset retirement obligation until the Lik Project goes into operation, which cannot be assured.
