Antipa Minerals: Developing a Gold-Copper Project in Australia with Exploration Potential

Key Concepts

• Antipa Minerals: An Australian exploration and development company focused on gold, copper, and silver.
• Patterson Province, Western Australia: Antipa's primary exploration area, located in northwest WA, adjacent to significant mines like Greatland Gold's Telfer mine and Rio Tinto's Winu copper deposit.
• Minari Project: A standalone gold-copper development opportunity being advanced by Antipa.
• Preliminary Economic Assessment (PEA): An initial study to assess the economic viability of a mining project.
• Pre-Feasibility Study (PFS): A more detailed study than a PEA, providing a more robust estimate of project economics and technical feasibility.
• Definitive Feasibility Study (DFS): The most comprehensive study, providing detailed engineering, cost estimates, and a high level of confidence for a final investment decision.
• Net Present Value (NPV): A measure of the profitability of an investment, calculated as the present value of future cash flows minus the initial investment.
• Internal Rate of Return (IRR): The discount rate at which the NPV of all the cash flows from a particular project equals zero.
• All-In Sustaining Costs (AISC): A measure of the total cost to produce one ounce of gold, including operating costs, capital expenditures, and other expenses.
• Mineral Resource: A concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction.
• Mineral Reserve: The economically mineable part of a Measured and Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study.
• FID (Final Investment Decision): The point at which a company commits to investing in a project.
• RPS Target: A specific exploration target within Antipa's portfolio showing significant gold-copper anomaly.
• Chester Asset Management, Jupiter, Franklin Templeton, K2, Conwave, Real Earth Resources Commodity Discovery Fund, 91, Greatland Gold: Key shareholders of Antipa Minerals.
• Telfer Gold Plant: Australia's third-largest gold and copper producing facility, owned by Greatland Gold.

Antipa Minerals Overview and Patterson Province Exploration

Antipa Minerals is an Australian company engaged in the exploration and development of gold, copper, and silver. Their primary focus is on a substantial exploration portfolio spanning over 4,000 square kilometers in the Patterson Province of Western Australia. This region is strategically located adjacent to established mining operations, including Greatland Gold's Telfer mine and Rio Tinto's Winu copper deposit, indicating significant geological potential. Antipa is actively exploring this vast landholding.

Minari Project: Pre-Feasibility Study and Economic Projections

The company is currently undertaking a Pre-Feasibility Study (PFS) for a standalone gold-copper development opportunity named Minari. This follows the completion of a Preliminary Economic Assessment (PEA) in October of the previous year.

PEA Highlights:

• Base Case Gold Price: The PEA utilized a conservative base case gold price of AUD $3,000 per ounce, which is significantly lower than the current market price (over AUD $6,000 per ounce).
• Project Life: A 10-year mine life was projected.
• Gold Production: An average recovery of 130,000 ounces of gold per annum for the 10-year period.
• Project Economics (Base Case - AUD $3,000/oz):
  • NPV (7% discount rate, post-tax): AUD $600 million.
  • IRR (post-tax): 46%.
• Project Economics (AUD $4,000/oz):
  • NPV (7% discount rate, post-tax): AUD $1.2 billion.
  • IRR (post-tax): 79%.
• Capital Expenditure: Slightly over AUD $300 million.
• Payback Period (Base Case): Just over two years.
• Payback Period (AUD $4,000/oz): Approximately 15 months, potentially less than a year at current prices.

The strong outcomes from the PEA have provided the board with the confidence to proceed with the PFS, which is scheduled for completion in July-August of the following year. A positive PFS will lead directly into a Definitive Feasibility Study (DFS), with a target for a Final Investment Decision (FID) around mid-2027.

Financial Position and Exploration Strategy

Antipa Minerals boasts a strong financial position, with AUD $61 million in cash reserves. This capital is expected to fund the company through the PFS, DFS, and up to the FID, with a projected treasury balance of AUD $10-15 million at that point.

Concurrently with the PFS, Antipa is executing significant discretionary exploration and resource growth drilling programs.

• 2024 Drilling: Approximately 100,000 meters of drilling planned, with 35,000 meters allocated to the PFS and 65,000 meters for resource growth and exploration discovery.
• 2025 Drilling: A similar volume of exploration drilling is anticipated for the calendar year 2026.

All-In Sustaining Costs (AISC) and Exploration Potential

The PEA reported an AISC of AUD $1,720 per ounce of gold produced, which is considered highly favorable.

Regarding exploration potential and mine life extension, Antipa is actively drilling to expand its mineral resources.

• Mineral Resource Updates: An update is expected before mid-December, followed by a subsequent update for the PFS around February of the following year.
• Exploration Focus: Efforts are directed towards extending resources proximal to the current development opportunity and exploring targets up to 30 kilometers away for potential satellite discoveries.
• RPS Target: Significant success has been observed at the RPS target, where a 2-kilometer long air core gold-copper anomaly has been identified. An RC rig is currently evaluating this target systematically.

Mineral Output and Financing Strategy

While gold is the primary focus, copper and silver are also present. The PEA indicated that the best economics were derived from a gold-only scenario, with silver being a co-product. However, the project also has the potential to produce a copper concentrate via flotation, with grades of approximately 15% copper and over 100 grams per ton of gold, similar to the Telfer operation. The PFS will continue to evaluate both gold-plus-silver and gold-copper-silver output scenarios.

Regarding financing the development, Antipa's board is currently contemplating conventional debt and equity arrangements, though other scenarios will be evaluated as the project progresses.

Shareholder Structure and Management Ownership

• Management Shareholding: Approximately 3%.
• Largest Shareholder: Chester Asset Management (Australia) holds just under 10%.
• Other Significant Shareholders: Jupiter (UK) with about 5.5%, and a range of other institutions (including North American entities like Franklin Templeton and K2, and European entities like Conwave and Real Earth Resources Commodity Discovery Fund) accounting for approximately 40% of the register.
• Corporate Shareholder: Greatland Gold is the largest corporate shareholder with about 6%.

Path to Production and Timeline

Antipa Minerals is on a fast track towards production.

• FID Target: Mid-2027.
• Engineering and Construction: Approximately 20 months post-FID.
• Commercial Gold Production Target: Around December 2028.

This timeline suggests a rapid development cycle, with a decision point in approximately 1.5 to 2 years, followed by construction and production. The company is operating in Australia, a favorable mining jurisdiction.
