(Mark Eddington | The Salt Lake Tribune) The headframe over the Big Hill shaft, which miners once used to access the urananium mine, is part of a 100-home development a prominent businessman is planning to build in Leeds on 148 acres, about half of which would be situated on land where uranium mining took place. Residents opposing the plan for Silver Pointe Estates claim elevated levels of radioactive and other contaminants on or near the site make the land unsuitable for a residential development.
