Abstract
The Krueger property was examined by an engineer of the Bureau of Mines in September 1943. The records of 23 old drill holes indicated an appreciable body of ore without delimiting the deposit. It appeared that additional drilling might increase this reserve sufficiently to justify mining. Accordingly, the Bureau of Mines drilled 5 churn-drill holes and 19 diamond-drill holes on the Krueger tract. The last of these holes concluding the Bureau?s project was completed in April 1947.
