Galaxy, which restarted its Mt Cattlin lithium mine and just completed a takeover of General Mining, has risen by over 1300% in the past year and now has a market capitalisation of $A685 million.
Peer Orocobre, which has been in production in Argentina since late 2014, has also benefitted from the increased interest in lithium.
Its shares have more than doubled over the past year and the company is now valued at $800 million.
In a booming gold sector, Resolute has been one of the biggest winners, surging by 600% under the leadership of former investment banker John Welborn.
The company has slashed debt and returned to paying dividends, with its market cap growing to nearly $1.2 billion.
Resolute and Galaxy have also been admitted to the ASX All Australian 50, while Galaxy will also join the ASX 300.
Also joining the ASX 300 is gold developer Dacian Gold, gold producer Doray Minerals and graphite player Magnis Resources.
Dacian has risen by over 600% over the past year, and with a market cap of $450 million, is worth significantly more than Doray ($233 million), despite Doray being a circa 140,000 ounce per annum producer.
The companies are both run by former Avoca Resources execs in Rohan Willliams (Dacian) and Allan Kelly (Doray).
Magnis shares have more than doubled this year as the company moves towards development of its Nachu graphite project in Tanzania.
For the first quarter in quite some time, no resources companies were removed from indices as part of S&P Dow Jones Indices' quarterly rebalance.
