From the Plaque:
Nestled between Stemwinder and Nickel Plate Mountains, the historic gold mining town of Hedley sprang up shortly after the yellow precious metal was discovered here in 1897. The town was named after Robert R. Hedley, mining engineer.
Both the mountain top Hedley Mascot and Nickel Plate mines extracted millions worth of gold, silver, and copper before finally closing in the 1950's after the ore body was exhausted. Today tourism brings new life to the town famous for gold.
