River-worn lumps of gold are typically called nuggets.

Well, isn't that just a happy little question? If we know the mass of the second lump of gold is 96.5 g, and we know the density of gold is about 19.3 g/cm³, we can use a little math magic to find its volume. By dividing the mass of the second lump by the density of gold, we find that the volume of the second lump of gold is approximately 5 cm³. Just like that, we've painted a clear picture of the volume of our second golden friend.

Depends a bit on what has been cast. A lump of gold or iron is an ingot, but if cast into a specific shape (like a model car) it would be a casting (not usually gold though!)
