Around eight million shares changed hands in strong, steady trade with a peak of some 690,000 changing hands just before 1pm.
Around $2.5 million worth of shares were traded as investors sought to get into the tightly-held stock, where the top 10 shareholders control around 57% of the share register, led by founder and renowned WA-based prospector Mark Creasy (31%), Independence Group (4.9%) and Mineral Resources' founder Chris Ellison (4.2%).
The company's initial public offer raised $15 million from the issue of shares valued at 20c.
Galileo will begin drilling in its Norseman prospect areas almost immediately, looking to boost its existing modest cobalt resources. It will also undertake a scoping study for a potential development, starting with diamond core samples.
It hopes to deliver results in the back half of the year.
The flagship Norseman project has a resource of 20.2Mt grading 0.11% cobalt and 0.53% nickel for 13,600t cobalt and 106,000t nickel for the Mount Thirsty Sill and Mission Sill.
The area carries an exploration target of 10-20Mt grading 0.1-0.12% cobalt.
A mining study has suggested 1Mtpa operation is viable.
Additional exploration suggests there is also potential for nickel sulphides.
Work at the earlier stage Fraser Range leases will start by reviewing past exploration to pinpoint around for ground geophysics and drilling.
The project covers the Kitchener and Yardilla zones of the extensive, 400km long, Fraser Range geological belt which was proven prospective for nickel mineralisation with the 2012 discovery of the Nova-Bollinger nickel-copper-cobalt mine, where Creasy was also a partner before its sale to IGO.
Most mineralisation is likely buried under cover.

Galileo managing director Brad Underwood, who owns 300,000 shares, pledged the company would work "diligently towards development of the Norseman and Fraser Range projects", where it was "100% focused" on adding resources and making new discoveries.
Based on yesterday' closing price Galileo was valued at $38 million.
