Auriferous quartzose fault breccia deposit. (See also "Miller adit, Lyman, Grafton Co.")

Gold was discovered in a stone wall on the Dodge farm by J. H. Barratt in June, 1866, leading to the discovery of a gold-bearing quartz vein. The farm was owned by Simeon Dodge (b. 1815). Initially worked by the Dodge Gold Mining Company. By 1869, $16,000 worth of gold had been produced at the mine. (Hitchcock, 1869)
