Mobilisation of Drilling Rig to Eureka Project

Mobilisation of Drilling Rig to Eureka Project

Ajax [AQSE: AJAX], the natural resources investment company focused on high-impact opportunities in South America, is pleased to announce that mobilisation of a drilling rig and associated ancillary equipment to the Eureka Gold and Copper Project, located in the Province of Jujuy, Argentina, will commence today.

Drilling activities are expected to begin later this week. The initial drilling programme (the "Programme") will comprise approximately 10 diamond drill holes for a total of approximately 1,500 metres of diamond drilling.

The Programme will target a series of shallow geochemical and induced polarisation ("IP") anomalies, as well as a deeper IP chargeability anomaly identified in a 2014 report authored by SRK Consulting. This deeper anomaly may represent the transition to a sulphide-rich zone within the mineralised system.

Drilling will be conducted in close proximity to Mina Eureka, the historic copper and gold mine within the Eureka Project area. Mina Eureka has a documented 400-year production history yet has never been drill tested, representing a compelling exploration opportunity.

The Eureka Project is drill-ready, with multiple highly prospective anomalies previously identified by earlier operators. High-grade copper oxides have been confirmed at surface, with historical samples reporting grades of up to 6.1% Cu, and numerous samples exceeding 0.5% Cu across several historical exploration programmes.

Ajax is committed to performing operational activities in compliance with the highest environmental and community engagement standards.

The commencement of drilling activities represents a highly significant milestone for the Eureka Project, which has never been drilled in its approximately 400-year history of production, marking a key step towards determining its untapped copper and gold potential and advancing the Company's strategy of transforming historically productive yet underexplored assets into value-generating opportunities for shareholders.

The Company expects to receive preliminary assay results by the close of the first quarter of 2026. Further updates will be provided in due course once drilling activities commence.

Underexplored Gold Potential

A historic, non-JORC compliant estimate indicates approximately 52,000 ounces of gold hosted by a basal conglomerates unit, with a 2007 NI 43-101 report suggesting placer potential may be several times greater, associated with a broader paleo channel. Ordovician quartz veins present a separate hard rock gold target. Codelco did not evaluate gold during previous work, leaving this upside untested across the district.

Red Bed Analogues: Additional Scale Potential

Eureka shares key geological traits with the Corocoro red bed copper system in Bolivia, which hosts approximately 80 million tonnes at 0.6% Cu.

While there can be no assurance that Eureka hosts mineralisation of comparable scale or grade, these geological similarities suggest potential for a larger stratabound copper system. These concepts will be further evaluated through the upcoming Programme.
