A fierce rivalry between Gwalia and neighbouring Leonora developed and a tram service was established between the two towns in 1903. From the 1920s, the town started to decline when external factors like the falling gold price started to affect the mine. On 21 December 1963, the gold mine at Gwalia closed and the town was reduced in population from 1,500 to 40. The Sons of Gwalia mining company was delisted for the first time on 4 February 1964. In 65 years of operation, the mine had produced 2,500,000 ounces of gold.
In the 1980s, a new Sons of Gwalia company, formed by the brothers Peter and Chris Lalor, descendants of Peter Lalor

 through a merger with Pacmin Mining. Tarmoola is located 40 km north of the Gwalia mine.

In December 2003, the mine was placed in care and maintenance after known gold resources were exhausted.

After a rapid rise of the company, unauthorised gold and foreign exchange trading activities by chief financial officer Eardley Ross-Adjie in the year to June 2000, ended up costing Sons of Gwalia more than A$190 million. Sons of Gwalia went into administration on 30 August 2004, following a financial collapse, with debts exceeding $800 million after suffering from falling gold reserves and hedging losses. Sons of Gwalia was Australia's third-largest gold producer and also controlled more than half the world's production of tantalum.

St Barbara purchased the mine from insolvent Sons of Gwalia in March 2005 with a three year plan to reopen it.

After a three year redevelopment, production resumed at the mine in September 2008, with the first gold pour being carried out in October 2008. The Hoover decline, named after the late President, was at 1,191 metres below surface as of 30 June 2009. The plant currently continues to operate on a campaign basis, one week on, one week off.
