How did the conquest of new lands most directly contribute to economic growth?

The conquest of new lands directly contributed to the economic growth of nations since through territorial expansion new territories were acquired that included within themselves enormous amounts of natural resources.

Thus, for example, the territorial expansion of Spain during the conquest of America allowed the Spanish Empire access to precious metals and different grains that contributed to the economic development of the nation and the well-being of its citizens.

Another example is that of the United States, which after the annexation of California was able to exploit the enormous gold reserves that were in the territory of the State.
