Cantera²

Metaphorically, use for depth, source, root, and foundation in what refers to the mind and its operations: and thus, one who has good ingenuity, and who is known to be useful and profitable for some thing or things, is said to have a good quarry: Of discourse, poems, and prayers, which are well executed and composed, and whose author is unknown, are said to come from a good quarry: and so of other things.  1729 Diccionario de Autoridades
