The cost of mining gold varies from mine to mine. For example, if the cost to mine it per ounce is $600 per ounce, it is profitable to mine when it trades much above that, but not profitable if it trades at that or at a lower price.

Lithogenous sediment is made up of fragments of rocks and minerals that have been eroded and transported by various geological processes before settling on the ocean floor. These sediments typically originate from continental sources and can include materials such as quartz, feldspar, and clay minerals. Lithogenous sediment forms a significant component of marine sedimentary deposits.
