The town has a post office, several shops, garages, and churches, a fire hall, a general store, and a new supermarket.
Cardiff is located in a highly slate-rich region, which created the town's early industries.
At the completion of the operation in the early 1970's, the shaft extended to a depth of over 300 feet with numerous tunnels at various levels.
Huge blocks of the serpentinite were lifted out by horst and cable, similar to the slate operations, and removed to the saws in nearby buildings.
The rock was used for decorative stone, lamp bases, table tops, fireplaces, and desk ornaments.
