There is an estimated $500 QUADRILLION dollars’ worth of resources on the Moon, and nations and companies are looking to mine the moon of its riches! This, of course, is a wild guess because all sorts of costs are involved in such recovery and there may be such an impact on the specific markets that the value could be much lower ...but still useful. Water and helium-3 are mentioned in this video, but other minerals and material are also likely present on the moon. For a historical review on lunar activities, see the I2M Web Portal "Search Results" (here), and the Memoir 101 of the Energy Minerals Division (AAPG) listed below, followed by the references used in the video.
