I80 Gold: Nevada Gold Project Development and Production Strategy

This presentation outlines I80 Gold's strategy for developing its Nevada-based gold projects, aiming for significant annual production through a hub-and-spoke model centered around the Lone Tree Autoclave. The company emphasizes its strong resource base, experienced management team, and a clear, low-technical-risk pathway to becoming a mid-tier gold producer.

Company Overview and Strategy

Leadership and Vision: Paul Shawan, COO of I80 Gold, highlights the company's industry-leading pipeline of Nevada-based gold projects. He expresses confidence in the assets, team, and jurisdiction, noting minimal technical risk.
Resource Position: I80 Gold is the fourth-largest mineral resource holder in Nevada, with all deposits open for expansion. The geology and metal endowment are well-understood.
Production Target: The company has a defined pathway to achieve approximately 600,000 ounces of gold per year.
Operational Model: The strategy involves feeding four brownfield assets (previously operating mines) with significant infrastructure into the Lone Tree Autoclave. Three of these are underground mines, and two are open pit mines under development.
Management Team: The management team is based in Reno, Nevada, and possesses extensive experience working for major mining companies in the region.

Resource Base and Economic Potential

Underground Resources:
- Over 1 million ounces of Measured and Indicated (M&I) resources at a high grade of 8.4 g/t.
- Approximately 2.5 million ounces of Inferred resources at 8.12 g/t, which are economic even at gold prices around $1,000 per ounce and highly economic at current prices.
Open Pit Resources:
- 5.5 million ounces of M&I resources.
- An additional 5 million ounces of Inferred resources.
Silver Resources: Significant silver resources are also present, with approximately 100 million ounces of M&I and 193.4 million ounces of Inferred.
Preliminary Economic Analyses (PEAs): PEAs have been completed and publicly disclosed to provide an indication of the economic potential based on existing resources.
Granite Creek Underground: PEA estimates show a Net Present Value (NPV) of approximately $550 million at a 5% discount rate and a gold price of $2,175/oz, significantly increasing at current spot prices.
Two Open Pits: PEA estimates indicate a combined value of over $1 billion at $2,175/oz, rising to over $3 billion at $2,900/oz.
Overall Value: The combined PEA values suggest significant economic potential, ranging from $1.6 billion to over $4.5 billion.

Phased Production Plan and Timeline

The company has prioritized projects into three phases:

Phase 1:
- Timeline: By 2028, achieve approximately 150,000 to 200,000 ounces of annual production from two open pits (Granite Creek and Archimedes Underground).
- Lone Tree Autoclave: Refurbishment of the Lone Tree Autoclave is underway.
Phase 2:
- Timeline: Several years later, by 2030-2031, expect production in the range of 300,000 to 400,000 ounces per year.
- Sources: This will include production from the Cove Underground and Granite Creek Open Pit.
Phase 3:
- Timeline: Approximately six to seven years from now (by 2032), reach the flagship target of 600,000 ounces per year.
- Note: The company is considering prioritizing Mineral Point ahead of Granite Creek based on ongoing technical work.

Project Development and Technical Work

Granite Creek Open Pit: Already drilled off to M&I status, allowing for immediate development without extensive further drilling.
Mineral Point: Technical work is more advanced, and the company is considering accelerating its development.
Production Ramp-up: The production profile shows a ramp-up through 2034, potentially reaching up to 800,000 ounces per year, with ongoing drilling to sustain production for many years. Mineral Point has an estimated 17-year mine life.
2025 Focus: Development phase, with a third-party toll milling agreement for ore from Granite Creek. Development of Archimedes and refurbishment of Lone Tree are also in progress.
2026-2027: Expected to have strong margins from Archimedes and Granite Creek Underground, with development on other open pit deposits.
Cost Estimates: Projected all-in sustaining costs are in the range of $1,400 to $1,500 per ounce.
Drilling Campaigns: Active infill drilling programs are ongoing at Granite Creek, Cove, and Archimedes to improve economics.

Permitting and Feasibility Studies

Phase 1 Permitting: Granite Creek Underground, Archimedes Underground, and Lone Tree Autoclave are virtually all permitted.
- Granite Creek: Water management requires an engineering design change.
- Archimedes: Permitted down to the 5100 level; work is ongoing for deeper levels.
