The Khewra Salt Mine (or Mayo Salt Mine) is Pakistan's largest and oldest salt mine and the world's second-largest. Also, it is a major tourist attraction, visited up to 250,000 visitors a year.
Salt from Khewra, also known as "Himalayan salt", is red, pink, off-white or colourless. Its history dates back to its discovery by the troops of Alexander III of Macedon "The Great", in 320 BC.
The Khewra Salt Mine is also known as Mayo Salt Mine, in honour of Lord Mayo, who visited it as Viceroy of India.
The mine is a part of the Salt Range that was originated about 800 million years ago.
In modern times it has been active since 1872.
The total reserves of salt in the mines are estimated from 82 million tons to 600 million tons.
In the early years of British rule, the Khewra mine produced about 28,000 to 30,000 tons per annum; it increased gradually and nowadays produces close 400,000 tons of salt, of about 99% pure halite per annum, which amounts to almost half of Pakistan's total production of rock salt.
The underground mine covers an area of 110 km² (43 sq. miles).
