Operational transformation and mine plan

• Florida Canyon mine has been transformed since its 2024 acquisition, with an updated technical report showing over 11 times the acquisition cost in after-tax free cash flow and a 74% increase in proven and probable reserves to nearly 1.2 million gold ounces.

• Mine life has been extended by three years to eight years of active mining plus two years of residual leaching, with annual gold production rising 17% to about 82,000 ounces.

• The updated mine plan leverages existing infrastructure, expands heap leach capacity, and incorporates two years of operational data for improved predictability and efficiency.

• The mine plan includes staged fleet replacement, operational enhancements, and a focus on self-funding future growth through cash flow.

• All expansions and upgrades leverage existing infrastructure, reducing execution risk and supporting future growth.

Resource, reserve, and production profile

• Updated mineral reserves stand at 1.19 million ounces of gold, achieved despite two years of mining depletion, driven by exploration, drilling, and inclusion of historic waste rock stockpiles.

• Production is forecast to average 82,000 ounces of gold per year, with a total of 685,000 ounces produced at an average recovery of 56.7%.

• The mine will process about 116.9 million tonnes of ore over its life, with annual mining rates aligned with recent performance and staged fleet replacement.

• Heap leach expansions are planned in two phases between 2026-2028 and two more in 2030-2031, all within the current operational boundary.

• 2026 gold production guidance is 70,000–75,000 ounces, rising to 80,000–85,000 ounces in 2027 and 2028.

Capital investment and cost structure

• $92 million in growth capital will be self-funded, with $55 million for heap leach expansions and $37 million for fleet modernization, including replacing aging loaders and haul trucks.

• $267 million in sustaining capital is planned, covering pre-stripping, fleet maintenance, and heap leach construction.

• Total sustaining and other capital costs are estimated at $379.7 million, with major investments in mobile equipment, heap leach expansion, and reclamation.

• Life of mine average cash costs are projected at $1,940/oz, with AISC at $2,331/oz; AISC for 2026 is revised to $3,300-$3,500/oz due to increased mining, inflation, and higher royalties.

• Significant cost reductions are expected after 2027.
