Dateline Resources Limited (ASX: DTR) is an Australian publicly listed company focused on mining and exploration in North America.

Welcome to Dateline Resources

Dateline Resources is an ASX-listed company primarily engaged in mineral exploration and development in the United States.

The Company owns 100% of the Colosseum Gold-REE Project. The Colosseum Mine is in the Walker Lane Trend in East San Bernardino County, California.

Situated less than 10km north of the Mountain Pass Mine, USA’s only operating rare earth mine, owned by MP Materials.

The Colosseum Mine is uniquely positioned to potentially hold valuable reserves of both gold and rare earth minerals, which is not unusual for this area, as the Mountain Pass mine was originally mined for gold.

The Colosseum Mine has a JORC Compliant Resource of 813,000 ounces of gold,

Additional exploration to materially expand the resource is underway.

Work has commenced on identifying the source of the mantle-derived rocks that are associated with carbonatites and are located at Colosseum.

A comprehensive mapping, sampling and gravity survey has located several REE targets that are ready to be drill tested.

Argos Strontium Deposit

Dateline Resources Limited has agreed to acquire an 80% interest in the Argos Strontium Project, located approximately 100 kilometres away from the Colosseum Gold and Rare Earths project in San Bernardino, California.

The Argos deposit comprises four patented mining claims covering 75 acres and is considered the largest strontium deposit in the USA.

Dateline is specifically interested in strontium’s application in the future of permanent magnets for EV car manufacture.

Q&A Opportunity with global REE experts Messrs Mariano discussing REE mineralisation at DTR’s Colosseum Project

“This is a bonanza result. The current drilling program is designed to increase the overall gold resource size, both in terms of tonnage and grade. The results from the first hole have yielded a materially higher gold grade than the resource average and bode well for when the resource is recalculated at the conclusion of the program.”

“We recently announced the sale of Gold Links Mine to focus on the Colosseum Mine, and drill intercepts such as this validate the strategy.”

“A resource upgrade could significantly increase the value of the Colosseum Mine. This is the first partial result of eight holes in the program. Progress and results from the other holes keenly awaited.”

Commenting on the results, Managing Director Stephen Baghdadi.
