Saturn Metals (STN) Company presentation summary

Project overview and resource base

• Apollo Hill Gold Project holds a 2.24Moz Au Mineral Resource, with 82% in Measured & Indicated categories and a Maiden Ore Reserve of 1.59Moz Au, reflecting an 86% resource-to-reserve conversion rate.

• The project is located in a major gold province in Western Australia, with 100% ownership of approximately 1,000km² of underexplored tenure.

• Pre-Feasibility Study (PFS) outlines a 14-year mine life with a 1.77Moz production target and a Net Present Value (NPV8%) of $973M at a gold price of A$4,300/oz.

• The project features low strip ratios (2.39:1), thick ore zones, and bulk mining potential, supporting economies of scale and low operating costs.

• Regional exploration and gravity surveys are planned to unlock further growth and resource expansion.

Metallurgy and processing

• Metallurgical testing shows excellent gold recoveries: 78–88% in fresh rock and oxide/transitional material using heap leach with HPGR crushing.

• The process uses low reagent consumption and demonstrates strong percolation and agglomeration characteristics, supporting efficient heap leach operations.

• PFS assumes a 73.7% recovery rate and a 160-day stacking schedule, with conventional heap leach processing.

Production and mining plan

• Life-of-mine production targets 117.4Mt at 0.47g/t for 1.77Moz contained gold, with an average annual recovered gold of 106koz over 12 years.

• Mining inventory is at surface, with large selective mining units and low unit costs, using 10m benches and 5m sub-benches.

• The project is designed for a 10Mtpa run capacity, with a simple, flat production schedule and a low-cost scenario.
