In veins cutting amphibolite & syenite gneiss; crystalline limestone
The deposit was originally explored for fluorite in 1943 by Cardiff Fluorite Mines Limited: exploration for uranium was conducted by Cardiff Uranium Mines Limited from 1953 to 1955. The mineralization extends for about 3 kilometers along the contact of geniss and crystalline limestone. The development at the South Zone consists of two adits, a shaft to a depth of 83.8 meters, and trenches. The openings are on the eastern slope of a ridge overlooking Irondale River.
It has been thought that material from other mines was processed on site but there has never been a mill on the property. The mine has since been rehabilitated.
