A possible solution could be something like this.

[REGIONRESOURCE mr_iron]
// default mining result.
// t_rock
SKILL=5.0,50.0
AMOUNT=5 25
REAP=i_ore_iron
REAPAMOUNT=3 12
REGEN=60*60
ON=@ResourceFound
IF (<src.findid(i_your_special_pickaxe_defname)>)
OBJ.f_setresource mr_iron
ELSE
OBJ.f_setresource mr_special_ore
ENDIF

[FUNCTION f_setresource]
FORITEMS 0
IF (<BASEID>==i_worldgem_bit) && (<TYPE>==t_ore)
MORE1=<ARGV[0]>
AMOUNT={4 9} // only necessary if you want other amounts
RETURN 0
ENDIF
ENDFOR
RETURN 1
