Vein rich with ore deposits (4)

I believe the answer is:

lode

(Other definitions for lode that I've seen before include "Vein of metal in the earth" , "Deposit of valuable ore running through other rocks" , "Mineral vein" , "Deposit of valuable ore found in surrounding rocks" , "Vein of metallic ore sounds heavy" .)

I've seen this clue in the LA Times.
