Lara Reports Results of Preliminary Economic Assessment for its Planalto Copper-Gold Project

On October 21, 2025, Lara Exploration announced the results of an independent Preliminary Economic Assessment (PEA) for its 100%-owned Planalto Copper-Gold Project in Brazil. The PEA demonstrates positive economics, highlighting an after-tax Net Present Value (NPV) of US$378 million at an 8% discount rate and an after-tax Internal Rate of Return (IRR) of 21%.

Key metrics from the PEA include: - Initial capital expenditure (CAPEX) of US$546 million. - An 18-year mine life with a 3.5-year payback period. - Life of mine production of 560,000 tonnes of copper and 111,000 ounces of gold. - The study utilized metal price assumptions of US$9,500 per tonne for copper and US$2,500 per ounce for gold. - The economic model is based on Indicated resources of 47.7 million tonnes and a significant Inferred resource of 154 million tonnes.

The release of a PEA is a significant de-risking milestone for an exploration company, and the headline numbers are robust. The after-tax NPV of US$378 million (approximately C$518 million) is over four times the company's current market capitalization of C$128 million, which on the surface, is highly positive and suggests significant upside.

However, a critical assessment reveals several substantial risks that temper the initial optimism: 1. Massive CAPEX: The initial CAPEX of US$546 million is a formidable hurdle for a company of Lara's size. Securing this financing will undoubtedly require bringing in a major partner, leading to significant dilution of Lara's interest in the project or potentially unfavorable joint-venture terms. 2. Aggressive Metal Price Assumptions: The PEA's attractive economics hinge on very bullish long-term metal prices of US$9,500/t copper (approx. US$4.31/lb) and US$2,500/oz gold. These prices are at the higher end of historical ranges and consensus forecasts. The project's NPV and IRR would be significantly lower, and potentially uneconomic, at more conservative price decks. The lack of a sensitivity analysis in the news release is a notable omission. 3. Reliance on Inferred Resources: The study's mine plan relies heavily on converting the large 154 million tonne Inferred resource into a higher confidence category. The PEA disclaimer correctly states that "Inferred Mineral Resources... are considered too speculative geologically" to be categorized as reserves. There is significant geological risk that a large portion of this inferred tonnage may not be successfully upgraded, which would materially impact the project's scale and economics.

Chronologically, this news follows a series of positive developments. In late 2024, the company strengthened its balance sheet by receiving over C$3 million from warrant exercises, giving it a healthy cash position of ~$5.6 million. In October 2025, it strategically acquired adjacent ground at Planalto, signaling confidence in exploration upside.

Conclusion: The PEA is a material and positive step forward. It establishes Planalto as the company's clear flagship asset with a defined economic potential, which is crucial for attracting a development partner. However, the announcement is not a game-changer due to the very significant risks associated with the high CAPEX, optimistic metal price assumptions, and the speculative nature of the inferred resources. The market will likely react positively to the headline NPV, but sophisticated investors will remain cautious until there is a clear path to funding the project and further de-risking of the resource.

Lara Exploration Ltd. is a prospect and royalty generator focused on identifying and advancing mineral deposits in South America. The company's business model is to acquire prospective exploration properties and advance them, often through joint ventures with other companies that fund exploration and development. This model minimizes dilution and financial risk for Lara's shareholders.

The company's flagship asset is the 100%-owned Planalto Copper-Gold Project, located in the Carajás Mineral Province of northern Brazil. As outlined in the October 2025 PEA, Planalto is a large-scale, open-pit development opportunity.
