Hi Frank,

Not to raise your hopes on hi Q, but step back and consider: Why would
current want to push its way through copper oxide when there is so
much conductive copper a micro-inch beneath it? This is like saying
insulated wire is non conductive because the plastic layer has so much
high resistance that current can't flow.

Copper oxide is only an issue if you are trying to penetrate it for a
contact (like in a switch, or a poor connection - tighten the screw).
