This is why resource reserves are usually accompanied by a price per unit:

The global uranium reserves with mining costs up to US $ 80 per kilogram amount to about 2 million tonnes ... If mining costs of up to 130 $/kg are taken into consideration the global uranium reserves are increased by further 3 million tonnes.

At some price, it will become possible to extract trace uranium from ocean water, of which there is quite a bit.
