The creation of U.S. Route 6, which passed through Mineral, was also an asset to the town, bringing in visitors from all over the country.

Mineral enjoyed great successes through the 1930s, 1940s, and 1950s, continuing to support its own school system and several small businesses including, at one time, three gas stations, three restaurant/taverns, an upholstery store, a motel, two grain elevators, two churches, a lumber yard, two grocery stores, a bank, a volunteer fire department, a library, a barbershop, a beauty shop, an ice cream parlor and Mineral High School.

All foreign traffic that previously traveled through town by the hundreds of cars a day, now took the quicker, more efficient route of I-80.

Today Mineral still supports a grain elevator, a restaurant/tavern, a library, a new post office, a Methodist Church, a volunteer Fire Department, and a trucking business.

A new ethanol plant is being built just two miles west of town and is bringing hope for a resurgence in population for the area.
