The Company’s restricted cash consists of money market accounts and short-term government bonds.

The bonding requirements for reclamation obligations on various properties have been reviewed and approved by the Wyoming Department of Environmental Quality (“WDEQ”), including the Wyoming Uranium Recovery Program (“URP”), and the Bureau of Land Management (“BLM”) as applicable. The restricted money market accounts are pledged as collateral against performance surety bonds, which secure the estimated costs of reclamation related to the properties. Surety bonds providing $27.8 million of coverage towards reclamation obligations are collateralized by the restricted cash.
