The first metal is determined as follows:
IF(E=1 AND D=1 AND C=1):  Pb
IF(E=1 AND D=1 AND C=0):  Sn
IF(E=1 AND D=0 AND C=1):  Fe
IF(E=0 AND D=1 AND C=1):  Cu
IF(E=1):                  Ag
IF(D=1 AND C=0 AND B=0):  Pb
IF(D=0 AND C=1 AND B=0):  Sn
IF(D=0 AND C=0 AND B=0):  Fe
ELSE:                     Au

The second metal is determined as follows:
IF(A=1 AND B=1):   Pb
IF(B=1):           Sn
IF(A=1):           Fe
ELSE:              Cu
IF(E=1):           Send metal to output
IF(D=1):           Skip adding two quicksilver to the second metal
IF(D=1 AND C=0 AND B=0): Add another two quicksilver to the second metal
IF(D=0 AND C=1 AND B=1): Add another two quicksilver to the second metal
