Exploration:

1953 – Uranium exploration was a huge target within the 1950’s. that gave way to high uranium prices. It would fist be explored by trenching and surface stripping over a length of 1,219.20 m. along the surface by Croft Uranium Mines, Ltd. Diamond drilling would total a length of 7010.40 metres which would be completed on this property.
 
1954 – Development work was mainly focus for gold-exploration as most of the sampling done was for gold. Erratically low gold grades were encountered through diamond drilling to warrant further work on the Croft Property. This encourage Croft Uranium Mines, Ltd., to conduct further exploration work by driving an adit into the outcrop. This adit would shortly after intersect the first ore-zone that would be sampled, and opened up even to the east and west. It was in view that the company had a substantial potential for a large tonnage production rate.
 
1955 – The property would later be taken over by Bicroft Uranium Mines, Ltd, and exploration/development work would be focus on the Centre Lake Zone. A minor amount of lateral development work would later in years reach the J Zone of the Croft Uranium Property. No additional work would be carried out on this property as the company was largely confined to mining the Centre Lake Zone.
