Horizon Gold (HRN) Investor Presentation summary

Project overview and resource base

• Gum Creek Gold Project hosts 44.5Mt @ 1.5g/t Au for 2.14Moz, with 63% indicated resources across 26 deposits on granted mining leases, mostly free-milling gold with >90% recoveries.

• Two main mineralised systems, Gidgee Shear Zone (886koz @ 1.53g/t) and Howards (267koz @ 0.81g/t), underpin the base mill feed, with a resource update expected in H2-2025.

• Largest gold resource in the Sandstone District, with historical production over 1.1Moz and last mining in 2005.

• Project benefits from established infrastructure, including a planned central mill at the historically permitted Gidgee site, existing haul roads, and tailings facilities.

• Located in a prolific Western Australia gold district with nearby consolidation opportunities.

Key deposits and exploration potential

• Gidgee Shear Zone is the main free-milling ore source, hosting 886koz (60% indicated), with mineralisation open along strike and at depth.

• Howards deposit is a 2.5km long zone with 267koz (80% indicated), no previous mining, and potential for resource growth at shallow depths.

• Kingfisher deposit has a history of high-grade production (265koz @ 4.0g/t open pit, 27koz @ 14.1g/t underground) and a current MRE of 2.17Mt @ 2.6g/t for 180.8koz.

• Omega deposit previously produced 84koz @ ~5.4g/t, with recent drilling intercepts indicating high-grade down-plunge extensions.

• Wilsons deposit offers 391koz @ 5.4g/t (93% indicated), not yet in the development plan, with strong metallurgical recoveries and further expansion potential.

Exploration and growth strategy

• 80km project strike remains significantly underexplored, with a recent 13,000m RC drill program focused on infilling and extending shallow oxide resources.

• Recent assays include 22m @ 3.18g/t Au (Swan/Swift), 28m @ 3.88g/t Au (Howards), and 14m @ 4.34g/t Au (Eagle).

• Further drilling is planned at untested resource targets, with a focus on shallow open pittable and high-grade underground resources.

• Resource growth has been consistent, with a 19% increase in May 2023 and further updates expected.
