argentiferous

If you learned basic chemistry, you might recall that the symbol for silver, "Ag," reflects the Latin name for the element, "argentum." That Latin term puts the luster in "argentiferous" and is also an ancestor of "argent," a word that was once used to refer to the metal silver and now means "the heraldic color silver or white." The country of Argentina owes its name to "argentum," as well.
