How to Find Gold, Using a few common placer gold rocks and minerals

Even fool's gold (copper-iron pyrites) give you one more gold tracer clue to help you find where gold is. That tracer is often concentrated with gold in placer deposits. Oftentimes you see iron, magnetite (black cubes), lead and pyrite in gold-bearing placers. This is because it's a heavier than average mineral containing iron and sulfides.
