In addition to the documentation of drill core sections, the cases contain slides depicting the following subjects: “Representative samples” of drill core fragments, drill core fragments in perspective, “physical characteristics” of the drill cores and the storage trays, the pit mine, a worker in a plaid shirt, close up shots of the geology of the working face, and images annotated “SHOTS OF JADE BOULDER CORE J5-J1”. Five slides originally filed separately and stamp dated “Jul. ‘73” depict what is speculated to be employees working on the diamond drilling project include 2 images annotated ‘R. Dickin Aug ‘72’, ‘I. Oliver Aug ‘73’, ‘S. Zimmer Aug ‘73’, and ‘core shack ’73’. The cases contain 234 7x7cm slides and at least 8 5x5 cm slides which are duplicates of the remaining images.
