Full Summary

Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) has completed the acquisition of 100% interest in the Argos Strontium Project, securing the largest known strontium deposit in the United States. This strategic acquisition strengthens Dateline's critical minerals portfolio at a time when the United States is prioritizing domestic production of minerals vital to national security. The Argos Project, located ~100 km from Dateline's flagship Colosseum Gold and Rare Earth Elements (REE) mine, will now be fully controlled by Dateline and advanced alongside its core gold-REE operations. The Argos deposit is known for its exceptional purity and geology, with high inherent ore grades and very low barium content. It is a celestite-hosted strontium deposit, with historical analyses showing up to 95% strontium sulphate (SrSO4) indicating very high purity celestite. The deposit consists of stratiform celestite beds near surface, making it amenable to open-pit mining. Dateline plans to integrate historical data and conduct further exploration at Argos, including modelling of gravity data, confirmatory drilling to define a JORC-compliant mineral resource, and metallurgical testwork. Developing Argos will complement, not distract from, Dateline's flagship Colosseum Gold and Rare Earths project, with the two projects being geographically close and sharing operational synergies.

Outlook

Dateline plans to progress Argos in a disciplined manner that adds value without detracting from Colosseum's development. The Company intends to leverage its existing regional expertise and stakeholder relationships to advance Argos efficiently in parallel with Colosseum.
