Horizon Gold (HRN) RIU Explorers Conference 2026 summary

Project overview

• Gum Creek Gold Project targets a large-scale, high-grade restart with 2.3 million oz at 1.9 g/t, 71% Indicated.

• Focus on two mining areas: Gidgee Shear Zone (1 million oz) and Howards (0.25 million oz).

• Feasibility study for a bankable project due at the end of the half year.

• 80 km underexplored Greenstone Belt with ongoing drilling and assays pending at Kingfisher and Omega.

• Six operating mills within 50-150 km provide regional processing options.

Historical context and resource details

• Project operated from 1989-2005, producing 80,000-100,000 oz/year at 3.5-6 g/t in a lower gold price environment.

• Located in the prolific Sandstone District, surrounded by multi-million ounce gold systems.

• Gidgee Shear Zone includes Swan, Swift, and Kingfisher ore bodies, with all pits open along strike for further exploration.

• Howards offers a bulk tonnage, low strip ratio opportunity, open in all directions.

• Previous underground mining at Swan and Omega revealed high-grade zones with significant upside at depth.

Development and exploration plans

• New 2.4 Mtpa CIL plant to be built, replacing the old 600,000 tpa mill.

• Initial focus on free milling open pits, with potential to bring underground mining forward.

• Base case targets 100,000 oz/year from open pits, with higher output possible from underground expansion.

• Drilling at Omega and Kingfisher aims to extend high-grade mineralization and test down plunge extensions.

• Established infrastructure and existing mining leases expedite permitting and development.
