SOLID FOUNDATION, REAL GROWTH AHEAD

Spring Hill Resources Opportunity

A high-grade, multi-zone gold project in Australia’s Pine Creek province with an 821,000 oz JORC Resource and significant expansion potential across a 5km mineralised corridor.

Project Location

Virgin gold system located within the +20Moz Pine Creek Province, just two hours from Darwin and supported by nearby infrastructure.

Large-Scale, High-Grade Gold System with Room to Grow

Large-Scale, High-Grade Gold System with Room to Grow

Located in the prolific +20Moz Pine Creek province, this advanced-stage project features a high-grade, sheeted vein system across a +5km mineralised corridor. Three key zones have been defined, each demonstrating scale and growth potential.

The core MRE Zone spans 1.1km and hosts a JORC Resource (June 2024) of 821,000 oz, including 424,000 oz Indicated, based on ~38,000m of drilling. Infill drilling underway aims to expand the resource along strike and at depth—where grades are increasing.

Post-IPO, the focus is to grow the MRE zone by proving up an Exploration Target of up to 350,000 oz, while also advancing the North Target Zone that has an Exploration Target of up to 900,000 oz. 

In addition, the Far North Zone will be evaluated in 2025 through mapping, soil sampling, and trenching.

Potential MRE Upside

Grade Improvement Evidenced Across The Board In Met Work To Date​

Proven Metallurgy with Exceptional Recoveries

Free-milling ore with exceptional metallurgy, delivering over 96% gold recovery in 24 hours and up to 70% gravity recovery, with larger samples consistently showing higher reconciled grades.

Conservative Grade Estimate Based on Fire Assays

The 2024 MRE by Cube is based entirely on fire assays, which are known to underreport grades in coarse gold systems—no Photon or Screen Fire assays were included.

POTENTIAL TO DEMONSTRATE GRADE UPSIDE​

Evidence of Underreported Grades

Historical screen fire assays (~10% of database) and metallurgical programs suggest coarse gold is not fully captured by standard fire assays, especially outside the oxide zone—potentially leading to undercalled grades.

Bulk Sample Confirms Coarse Gold Uplift

A 13,250t bulk sample processed at Union Reef showed a +45.6% uplift in recovered grade (2.33g/t vs. 1.66g/t SFA), confirming significant coarse gold contribution.

Photon Assay Re-Sampling Underway

A major re-assay program is targeting 40% of mineralised samples from 2010 onward, using Photon Assay to replace legacy fire and screen fire assays with faster, more representative results.

Potential for Higher Grade and Confidence

Larger, more accurate sample testing could drive a material uplift in future MRE updates, improving both grade confidence and resource decision-making.
