A roadcut on highway 28 East 800 meters East of the road to the York River Skarn, Morrison, and Davis Quarries. The roadcut is on the south side of the road and consists of a pegmatite vein cutting amphibolite.
This locality appears to include an exposure of the Mallard Lake metagabbro: "The assemblage in question is a foliated metagabbro forming a facies of the large Mallard Lake gabbro mass of Dungannon Township in Hastings County, Ontario, at a point 3/4 mile East of York River Bridge on the East Road out of Bancroft. The north end of this metagabbro intrusion has been mapped by Hewett in Carlow Township and it is known to extend southwest as far as Egan Chute on the York River near York River Bridge (Hewitt, 1955). The rock is a schistose metagabbro of medium grainsize..." Tilley (1957) published chemical analyses of both anthophyllite and magnesiohornblende from this locality.
