I believe the answer is:
miner
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">ore seeker</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for miner that I've seen before include "Underground labourer" , "Person who works underground" , "it's the pits, for me" , "One who digs for ore" , "One sent down for work" .)
