The apparent drop in resistivity originally shown by the Koreans can be attributed to the Cu2S phase change. The crystal structure changes with temperature, and that changes its conductivity. The resistivity never becomes zero but drops sharply to near-zero. It's so cleanly explained, I can't believe it's not over so it has to be over.
