With others, in Seattle, Blewett founded the Blewett Gold Mining Company, which acquired the Culver Company in 1892. The new company developed the mine and mill along Peshastin Creek in the Wenatchee Mountains and formed the now-abandoned mining town of Blewett, Washington, near what is now called Blewett Pass. Ownership conflicts of the successful mine were ultimately settled by the Washington State Supreme Court in 1913 in Hadley v. Washington Meteor Mining Company.
