Au Equivalent Calculation

SXGC considers that both gold and antimony that are included in the gold equivalent calculation ("AuEq") have reasonable potential to be recovered and sold at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by Alkane Resources Ltd contains two million ounces of equivalent gold (Mandalay Q3 2021 Results), and in 2020 was the sixth highest-grade global underground mine and a top 5 global producer of antimony. SXGC considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd in its 2024 End of Year Mineral Reserves and Resources Press Release, dated February 20, 2025. The gold equivalence formula used by Mandalay Resources was calculated using Costerfield's 2024 production costs, using a gold price of US$2,500 per ounce, an antimony price of US$19,000 per tonne and 2024 total year metal recoveries of 91% for gold and 92% for antimony, and is as follows: = (/) + 2.39

× (%)

Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, SXGC considers that a = (/) + 2.39 × (%)

is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.

THE INVESTMENT CASE

Grade × Scale × Strategic antimony

One project. Three reasons it's different from everything else in the room.

In March 2025 SXGC disclosed an Exploration Target for the Sunday Creek Project of 8.1 to

9.6 million tonnes at a grade of 8.3 g/t AuEq to 10.6 g/t AuEq for 2.2 Moz AuEq to 3.2 Moz AuEq. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource as defined by the CIM Definition Standards and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration Target should not be misunderstood or misconstrued as a Mineral Resource or Mineral Reserve. The Exploration Target has been prepared and reported in accordance with the 2012 edition of the JORC Code and is consistent with National Instrument 43-101 - Standards of Disclosure for Mineral Projects. The Exploration Target ranges are listed in the table below.

BASIS FOR THE EXPLORATION TARGET

The Exploration Target is based on geological interpretation and projection of mineralization intersected in diamond drilling. The target area encompasses three prospects along the main structure at Sunday Creek: Rising Sun, Apollo, and Golden Dyke. The tonnage and grade ranges reflect the geological uncertainty inherent in early-stage exploration and are based on:

• Interpreted geometry of the host structures from drilling

• Observed widths and extents of mineralized zones

• Variation in gold and antimony values from drill intersections

*2.39 AuEq Factor

The potential quantity and grade of the Exploration Target is conceptual in nature and therefore is an approximation. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. The Exploration Target has been prepared and reported in accordance with the 2012 edition of the JORC Code.

THE ASSET WE REPRESENT

This is a gold project with a strategic metal

104 individual intercepts exceeding 10% Sb. Top hit 56.5% Sb over 0.3 m.

Why the Western world cares

Munitions input - armour-piercing rounds, tracers, primers. Night-vision equipment, flame retardants, solar cells, batteries.

US defence stockpile ≈ 1,100 tonnes against ≈ 23,000 tonnes of annual US

industrial demand. That's the gap.

Costerfield (Alkane Resources) is the largest Western Sb producer. Sunday Creek- 60 km away, same corridor.
