Could be anything, depending on if the puddle is near the front or rear. Could be something as simple as a radiator hose, or it could be a freeze plug, a water pump, an intake manifold gasket, a head gasket, etc.
If you don't have a cooling system pressure tester you should either rent one, buy one, or go to a shop that has one, and pressurize the system to locate the leak. The tester just goes onto the radiator in place of the radiator cap and allows you to pump up to about 15 pounds of pressure into the system, you usually don't even need to use that much pressure to see where the anti-freeze is leaking from when there is a big enough external leak to leave a puddle.
