# Rise Gold's writ to compel Nevada County denied; Court finds mining right abandoned by 1963; plans appeal

## Summary
- Superior Court denied Rise's Writ of Mandamus seeking recognition of a vested right to operate the Idaho-Maryland Mine.
- Court ruled that a constitutional right to mine vested in 1954 but that Idaho-Maryland Mine Corp. abandoned it by 1963.
- Rise plans to appeal, arguing the Court erred on evidence standards and ignored intent to preserve mining rights.
- If appeal fails, Rise may file a Fifth Amendment takings action against Nevada County, estimating mineral estate value at $400 million+.
- CEO cited errors: Court ignored equipment sales to preserve property and required no evidence from County on intent.
