Directions to the Mine


The Ace of Diamonds Mine is located on NYS Route
28 within the village limits of Middleville.

Traveling from the WEST, use Exit 30 (Herkimer) NYS Thruway to
NYS Route 28 North. (We are approximately 9 miles
from the Herkimer Exit).

From the EAST use Exit 29A (Little Falls) NYS Thruway to NYS Route 169, at Middleville, turn left onto NYS Route 28, South. (We are
approximately 13 miles from the Little Falls Exit).

A road cut in the dolomite rock exposing a rock ledge readily identifies our place.
