California court denies Rise Gold's claim to vested mining rights at Idaho-Maryland Mine, plans to appeal.

The Superior Court of California ruled against Rise Gold Corp., denying its request to compel Nevada County to recognize its vested right to operate the Idaho-Maryland Mine. The court found insufficient evidence that the mining rights were preserved, concluding the rights were abandoned by 1963 despite Rise's claims of intent to resume mining. Rise Gold's CEO criticized the ruling, stating the court ignored key evidence and misapplied constitutional principles. The company plans to appeal, warning that failure could lead to a takings claim worth an estimated $400 million based on the mineral estate's value.
