Mining claims, although they may be inexpensive, are not designed for residential housing. Generally, the Federal Government still owns the land, while you have ownership of the mineral rights. In essence, these deals are designed for you to use the land for mining, not for living. As such there are restrictions such as not allowing anything to be build on the property that is not relating to the activities of mining specifically. On site camping is allowed, such as 14 days out of the month for the purpose of on site mining activities.
