As a mining geologist I must say that I doubt your rock has free, coarse gold in it, as it's incredibly rare. Usually hard-rock gold is microscopic and is impossible to collect without advanced milling processes. For example, this piece of milky quartz looks like a plain white rock, but when assayed it ran 14 grams of gold per ton.

Another essential piece of equipment used in hard rock gold mining is impact crushers. These machines use high-speed impact forces to crush rocks against anvils or breaker plates. They are particularly useful for reducing large chunks into smaller, more manageable sizes. Grinding mills are also vital in the hard rock gold mining process.
