He documented this work in an AIME publication in 1940.War yearsIn 1942, Lundberg was asked by the US government to carry out an exploration program in Greenland to investigate the presence of the mineral cryolite (an uncommon mineral then used as a flux in the manufacture of aluminum) at that time a strategic mineral for the war effort. Greenland was deemed as occupied territory (Demark was occupied by Germany at the time) so Lundbergs clandestine mission was likely sponsored by the OSS (precursor to the CIA). Lundberg also authored a number of position papers regarding the war effort, including a co-authored paper with Norm Keevil Sr. entitled Geophysics and the Ontario War Effort.
