Immediately south of the Junction North mine was Mineral Lease No.39 pegged in 1884 by Penglase and Carson and named the Great Northern Junction forming a continuation of the orebody beyond the break caused by the British mine geological fault.

Broken Hill Junction Silver Mining Company Limited was registered in 1886.

Three shafts were sunk Browne, King and McIntyre and small rich pockets of ore were won from the upper levels. The Junction erected its own smelter plant at Port Adelaide in 1890.

In 1889 the manager of the mine began manipulating Junction shares on the stock market. From time to time he would issue reports of the lode being worked out, causing a fall in share prices. Later, the discovery of rich ore would be announced, and share prices would rise again in the meantime permitting the manager and other speculators to reap a profit.

Alfred Arthur Greenwood Hales was a young journalist, the first mining reporter for the Barrier Miner newspaper when it made its debut on 28 February 1888. Known as 'Skite' Hales to his boyhood friends in the Adelaide suburb of Kent Town, he introduced himself as 'Smiler' Hales upon arriving at Silverton in 1886. He became a crusader, intent upon exposing worthless claims, such as the Dainty Davie, the Mystery, and other bogus mines in the district. Suspecting that something was amiss at the Junction mine, Smiler Hales accompanied by several fellow journalists climbed down the mine at night via an old prospecting shaft and found a splendid lode of silver ore in a stope which the manager had claimed contained no ore. Hales reported full details of the incident in his paper. Francis Jolly, the manager, placed an advertisement in the same newspaper forbidding Hales to enter the mine.

Some weeks later, rumours were circulating again that all was not well at the Junction mine. Jack Carden, manager of the Barrier Miner and formerly of the London Times, instructed Hales to 'get down the mine and find out what's going on'. With his fair moustache removed, his face dyed black, and wearing a loud check suit with heavily padded shoulders, Hales passed himself off as a negro boxer from a visiting troupe. He was permitted to enter the underground workings where he obtained several ore samples which, when assayed, revealed the presence of an undisclosed rich silver lode.

The publicity given in the Barrier Miner and which also featured in capital city newspapers, prompted the resignation of the mine manager. A.G. Hales later became a war correspondent and the author of 65 novels, mainly featuring a Scottish-Australian character named McGlusky. Hales died in London in 1936 at the age of 76.

A serious 'creep' occurred at the Junction mine in 1897, resulting in the collapse of stopes 205 ft below the surface. An extensive underground fire in 1906 necessitated the complete flooding of the mine, which also seriously affected the adjoining Junction North, and North mine underground workings. The history of the Junction company was one marred by inefficiency and intrigue. A number of Broken Hill shareholders forced the resignation of the board of directors in 1909 because of mismanagement and heavy losses. The company struggled through until 1923 when the mine was acquired by Sulphide Corporation Limited. It was purchased by North Broken Hill Limited in October 1929 and became the property of Broken Hill South Limited in 1962. Following the demise of the South mine in 1972, the lease was transferred to Minerals Mining and Metallurgy Limited.

Although ore to the value of $2.4 million was extracted by the Junction company, the shareholders received only $175 000 in dividends during the mine's existence of 37 years.
