Grey mineral; chief ore of lead (6)

I believe the answer is:

galena

(Other definitions for galena that I've seen before include "Commonest ore of lead - Angle "A" (anag)" , "Len, GAA produces lead sulphide" , "Angela (anag) - ore producing lead" , "Lead sulphide mineral" .)

I've seen this clue in The Mirror.
