The Calcium Carbonate was hidden in Area 51,Nevada. A secret Lucian stronghold. Whenever the locals try to discover what was in there, the Lucians seize them and make it look like it was an alien abduction. The other branches use technology and devices to discover it, but they never succeed. Eisenhower Holt suspected there was a clue in Area 51, and he may or may not have stolen it from their Lucian rivals.
