Mills Red Lake Gold Mines Ltd., was incorporated in 1944 to acquire the property. The property was purchased by Madsen Red Lake Gold Mines ltd. in 1963. During 1944, a geological survey was mad of the property, and later in the year, 7 holes were drilled with a total lenth of approx. 1280 m. In 1964 a magnetometer survey was completed on the property, and a detailed geological survey was completed in 1965. Most of the assays that were returned from drill core ranged from thrace to 0.02 oz/ton (0.69 g/tonne) Au. The highest assay, taken over 1.52 m was 0.16 oz/ton (5.46 g/tonne) Au. A check assay on this section returne 0.12 oz/ton (4.11 g/tonne) Au.

Dec 07, 2005 (K R Kettles) - The northern portion of the Mills property is underlain by thin units of ne (010 deg) striking spherulitic dacites which are intruded by metagabbro dikes and/or sills up to 150 m in width. Rock units dip steeply to the southeast. The southern portion of the property is underlain by dacitic metavolcanics, with only a few metagabbro and dioritic sills and/or dikes. Small 090 deg to 110 deg striking shear zones have been observed on the property. Diamond drilling intersected a quartz diorite dike or sill which contained thin auriferous zones reported to contain pyrite. The magnatometer survey did not reveal any major anomalies and only slight variations between the volcanic rocks and intrusives were noted.
