Horacalcum doesn't have a source listed, but it seems to be from Shards of Sin (2012) from Paizo. Geranite, on the other hand, is from Godmetals of Porphyra (2013) by Purple Duck Games. It's not uncommon for 3rd parties to change the names of Paizo-created game elements and make small changes to the description to avoid copyright issues. d20pfsrd does this quite a lot. For example, they changed the Wayang Spellhunter trait to the Metamagic Master trait and the Magaambyan Arcanist prestige class to the Collegiate Arcanist prestige class. My guess is that Purple Duck Games did something similar here.
