Dateline Resources Limited (ASX:DTR) recorded notable share price movement on 9 February 2026, trading at AUD 0.32, up 10.53% on the day. The increase follows the company’s announcement confirming the completion of infill gravity, magnetic, and radiometric surveys at its Colosseum Gold and Rare Earth Project in California.

Over the past month, the stock has gained 12.50%, while six-month returns stand at 125.00%. Year-to-date performance reflects a rise of 41.82%, coinciding with a period of increased technical activity at the project level.

Completion of Infill Geophysics at Colosseum
The company confirmed that the infill geophysics program was completed across its 100%-owned Colosseum Project. The work included a high-resolution ground gravity survey with 543 stations on a 100 m × 100 m grid and a magnetic and radiometric survey covering approximately 8.6 km² at 50 m line spacing.

These surveys follow an induced polarisation program completed in December 2025 and are intended to refine resolution over structural corridors identified in earlier datasets.

Data Integration and Drill Targeting Progress
All newly acquired datasets are currently being integrated with previous IP and magnetotelluric surveys by Mitre Geophysics. According to the company, this process is focused on refining structural geometry, linking deep geophysical responses with mapped geology, and finalising priority drill targets where multiple datasets converge. The updated interpretation is expected to guide more focused drill testing compared with earlier broad-based target definition.

Drilling Schedule and Project Context
Dateline Resources advised that diamond core drilling rigs are scheduled to arrive on site next week, with drill planning progressing alongside ongoing interpretation work. The Colosseum Project hosts a reported mineral resource of 27.1 Mt at 1.26 g/t Au for 1.1 Moz of gold, with over 67% classified as Measured and Indicated, and mineralisation described as open at depth.

With recent share price gains aligning with the completion of infill geophysical surveys and upcoming drilling activity, Dateline Resources is moving through a phase focused on data integration and target refinement at the Colosseum Project. Market participants are monitoring how forthcoming drill results align with the company’s stated exploration program and project development milestones.
