It is located on U.S. Route 60, approximately 10 miles (16 km) west of Van Buren in Pike Creek Valley.

Like most communities that came to be in Carter County, Fremont's origins can be tied to the activity of the Missouri Lumber and Mining Company.

In 1887 they granted the Current River branch of the Frisco Railroad a right-of-way across their land in Carter County.

Even after the name was changed to Fremont the town continued to be listed as Peggy on some maps for a number of years afterward, the 1911 Rand McNally & Co Atlas being one example.

In 1917 an iron smelter was built along Pike Creek about 2 miles (3 km) north of town, and the community of Midco was created.

After the need for iron diminished, the community dissolved, leaving only the smelter's smokestack and the Midco Cemetery on the hill east of the site as a reminder of the town's existence.
