Dateline Resources (DTR) has completed its first diamond drilling program at the Colosseum gold mine in California.

Through the five-hole program, the US-focused gold producer sought to confirm historical data it had compiled over the past 12 months since acquiring the project.

The information compiled from pre-mine exploration mostly correlates with the bench plans and reconciliation reports, according to Dateline.

Moreover, the data indicates the grades tend to increase with depth and the mine closed before many of these zones could be recovered.

Core and cuttings from this latest round of drilling will be compared to the resource information that has been compiled, and used to confirm the quantum of the remnant mineral resource.

The mineral resource estimate (MRE) is due to be announced in the June quarter, however the company expects that upside potential will remain to be tested beyond this initial estimate.

Dateline also completed a groundwater quality assessment at the mine, including assessment of sulphur crystals in both fresh and oxidised material.

The company said this process, and distinguishing between natural background sulphate in the un-mined areas from a separate sulphate isotope fingerprint from milling activities, is important for future mine plans.

“The database compilation of exploration, mining and water quality information suggests the mineralised zone at the Colosseum is open at depth,” Dateline’s Managing Director Stephen Baghdadi said.

“The data gathered will be used to formulate a commercial and environmentally sound
plan for the Colosseum project.”

Company shares were trading grey at 11.5 cents at 10:02am AEST.
