RI 4340 Investigation Of The Argall (Baggaley) Zinc-Lead Mine, Iowa County, Wis.

In August 1943 the Bureau of Mines completed seven churn-drill holes in an area of old mine workings near Linden, Wis., formerly known as the Argall mine. The work was undertaken as part of a general investigation by the Bureau of the zinc and lead producing area of southwestern Wisconsin at a time when special effort was being made to increase the production of metals necessary for war. The area was selected for investigation on the basis of its favorable geologic structure, past history, and apparent mineralization.
