The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islan.
Maug, one of the three islands within the Islands Unit of the Mariana Trench Marine National Monument, is the second northernmost island in the Marianas arch.
Scientists have discovered what they call a lost world more than 2000 metres below the surface in the Southern Ocean, near Antarctica. . Report by Mark Mo.

Measuring the Greatest Ocean Depth
The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters. If Mount Everest, the highest mountain on Earth, were placed at this location it would be covered by over one mile of water.
The first depth measurements in the Mariana Trench were made by the British survey ship HMS Challenger, which was used by the Royal Navy in 1875 to conduct research in the trench. The greatest depth that they recorded at that time was 8,184 meters (26,850 feet).
In 1951, another Royal Navy vessel, also named the "HMS Challenger," returned to the area for additional measurements. They discovered an even deeper location with a depth of 10,900 meters (35,760 feet) determined by echo sounding. The Challenger Deep was named after the Royal Navy vessel that made these measurements.
In 2009, sonar mapping done by researchers aboard the RV Kilo Moana, operated by the University of Hawaii, determined the depth to be 10,971 meters (35,994 feet) with a potential error of ± 22 meters. The most recent measurement, done in 2010, is the 10,994 meter ( ± 40 meter accuracy) depth reported at the top of this article, measured by the United States Center for Coastal & Ocean Mapping.

AngloGold Ashanti's Mponeng gold mine, located south-west of Johannesburg in South Africa, is currently the deepest mine in the world. The operating depth at Mponeng mine ranged from between 2.4km to more than 3.9km below the surface by the end of 2012. Ongoing expansions have resulted in deeper digging at Mponeng, pushing the record to beyond the four kilometre mark.

Gold may occur as deposits called lodes, or veins, in fractured rock. It may also be dispersed within Earth's crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust. Chemical differences in the fluids and the rocks, as well as physical differences in the rocks, create many different types of lode deposits.

Rescue (2015)

Five years after the collapse of the San Jose gold and copper mine that trapped 33 miners for 69 days, CNN correspondent Rosa Flores travels to Chile to speak with three of the miners. She also speaks with the drillers who worked around the clock on their improbable and miraculous rescue. The hour-long CNN Special Report, A Miner Miracle: Five Years After the Chilean Rescue airs Tuesday, August 4, at 9pmET/PT on CNN and via CNNgo.
Jorge Galleguillos can’t shake the tragedy from his mind. He was one of the 33 men trapped a half-mile beneath the hard rock of Chile’s Atacama Desert. He remembers praying to live while preparing to die. Finally, a small drill broke through to the men, allowing them to send an astounding message: ‘All 33 of us are alive.’ Their 69 days underground and their triumphant rescue stunned the world who watched it live on television. The men became globe-trotting celebrities with multiple movie and book offers; however, five years later, Galleguillos and most of the miners still live very humble and difficult lives. Many of the men battle demons and have trouble keeping steady work. And no one was ever held accountable for the collapse of the San Jose gold and copper mine.
During the CNN Special Report, Flores interviews former Chilean President Sebastian Pinera, whose optimism for their rescue rallied a nation and the world. She also speaks with Jeff Hart, the drilling expert who successfully carved a tunnel through the earth and helped save the 33 courageous men.
