Emerita Announces Positive IBW Pre-Feasibility Study Results Highlighting US$776 Million After-Tax NPV (8%), 23.51% IRR and 21-Year Mine Life

Emerita’s PFS for IBW projects a $1,019M NPV and 21-year mine life, but faces major hurdles.

What the company is saying

Emerita Resources Corp. (TSXV:EMO, OTCQX:EMOTF, FSE:LLJA) is presenting the completion of a Pre-Feasibility Study for its 100%-owned Iberian Belt West (IBW) project in Spain as a major technical and economic milestone. The company frames the PFS as demonstrating the viability of developing IBW into a high-grade polymetallic underground mine, emphasizing a 21-year mine life, robust NPV, and IRR figures. President and CEO Joaquin Merino highlights the multidisciplinary nature of the study and the opportunities for further optimization, while Executive Chairman Joseph Belan points to a rigorous review process involving independent board members. The announcement stresses the project’s scale, with three open deposits, substantial land holdings, and proximity to key infrastructure. The company acknowledges material risks in permitting, financing, and execution, but maintains a confident tone about IBW’s potential and its commitment to regional development. The narrative is forward-looking, with much weight placed on modeled economics and future optimization, and only limited discussion of the significant execution risks ahead.

What the data suggests

The PFS models a 21-year underground mining operation at IBW, processing ore from La Romanera, El Cura, and La Infanta via conventional flotation to produce four saleable concentrates. The base case assumes long-term metal prices of US$11,470/t copper, US$2,050/t lead, US$2,980/t zinc, US$3,750/oz gold, US$52/oz silver, and US$274/t pyrite concentrate. Initial capital costs are US$566.7 million, with total project capital at US$858.2 million. Life-of-mine unit operating costs are US$86.49/t ore processed, with total on-site and off-site costs of US$2,028 million and US$886 million, respectively. The mine plan is underpinned by a maiden Probable Mineral Reserve of 23.4 million tonnes at 2.30% Zn, 1.13% Pb, 0.45% Cu, 53 g/t Ag, 1.07 g/t Au, and 33.85% S. The PFS yields an after-tax NPV (8%) of US$776 million, IRR of 23.51%, and payback from production start in 1 year 11 months. At September 2026 spot prices, NPV rises to $1,019 million and IRR to 27.13%, with payback in 1 year 6 months. The updated July 17, 2026 Mineral Resource Estimate reports 26.1 million Indicated tonnes at 2.27% Zn, 1.12% Pb, 0.45% Cu, 52.0 g/t Ag, 1.04 g/t Au, and 33.2% S, plus 9.9 million Inferred tonnes at slightly lower grades. Pyrite concentrate is the main economic driver, contributing 66% of NSR. The study is detailed and NI 43-101 compliant, but all economics are modeled and contingent on future permitting, financing, and construction. No revenue, profit, or cash flow is realized; all figures are projections.

Analysis

The announcement presents the completion of a Pre-Feasibility Study (PFS) for the IBW project, which is a significant technical milestone and is supported by detailed NI 43-101 compliant data, including capital costs, resource/reserve estimates, and economic projections (NPV, IRR, payback). However, the majority of the value claims (NPV, IRR, mine life, payback) are forward-looking and contingent on successful permitting, financing, construction, and commodity price assumptions. The project requires a large initial capital outlay (US$566.7 million initial, US$858.2 million total), but there is no indication that financing is secured or that permitting is imminent, making the timeline for value realization long-term and uncertain. The tone is optimistic and frames the PFS as demonstrating 'technical and economic viability,' but this is based on modeled scenarios rather than realised outcomes. The company does acknowledge material risks and next steps, which tempers the hype, but the gap between narrative and actual progress remains material.

Risk flags

• ●Permitting risk is high, as the project requires multiple environmental approvals, regulatory reviews, and community engagement processes before construction can begin. The company explicitly lists these as material risks, and there is no evidence that any major permits have yet been secured.
• ●Financing risk is substantial, with initial capital costs of US$566.7 million and total project capital of US$858.2 million. There is no indication that funding is in place, and the ability to raise this capital will depend on market conditions and the company’s ability to de-risk the project further.
• ●Execution risk is significant due to the complexity of developing a multi-deposit underground mine with a 21-year life, including challenges in engineering, water management, procurement, and construction. The company acknowledges these risks and the potential for delays or cost overruns.
• ●Commodity price risk is material, as the modeled economics depend on long-term price assumptions for copper, zinc, lead, gold, silver, and pyrite concentrate. The more optimistic scenario, with a $1,019 million NPV, is contingent on achieving or exceeding September 2026 spot prices, which may not be sustained.
• ●Resource conversion risk exists because a substantial portion of the resource remains in the Inferred category and is excluded from the mine plan. There is no certainty that additional drilling will upgrade these resources to reserves or extend mine life.

Bottom line

Emerita’s PFS for the IBW project in Spain lays out a technically detailed and economically attractive mine plan, with a modeled after-tax NPV (8%) of $776 million (base case) and up to $1,019 million at higher spot prices, a 21-year mine life, and robust IRR and payback metrics. The study is comprehensive and NI 43-101 compliant, but all value is forward-looking and contingent on successful permitting, financing, and construction—none of which are secured or imminent. The capital requirements are high, and the project faces significant execution, permitting, and commodity price risks, which the company acknowledges. Investors should treat the PFS as a necessary de-risking milestone, not a guarantee of future cash flow or project build-out. The most important takeaway is that IBW’s modeled economics are strong, but realization of value is years away and subject to major hurdles. The next critical disclosures will be progress on permitting and financing; without these, the PFS remains a theoretical exercise.

Announcement summary

(TSXV:EMO) (OTCQX:EMOTF) (FSE:LLJA) Emerita Resources Corp. has announced the positive results of a Pre-Feasibility Study (PFS) for its 100%-owned Iberian Belt West project (IBW) located in the Iberian Pyrite Belt, Huelva Province, southwestern Spain. The PFS was prepared in accordance with NI 43-101 and demonstrates the technical and economic viability of developing IBW into a high-grade polymetallic underground mine. Joaquin Merino, President and CEO, stated that the PFS is the culmination of two years of multidisciplinary studies and identifies opportunities for further optimization. Joseph Belan, Executive Chairman, noted that a technical committee with two independent board members provided additional oversight of the PFS results and optimization recommendations. IBW is royalty-free, 100% owned, and hosts three high-grade polymetallic deposits: La Romanera, El Cura, and La Infanta, all of which remain open along strike and at depth. Emerita holds 15,023 hectares of land grants in the Iberian Pyrite Belt, with IBW comprising 1,546 hectares. The PFS supports an underground mining operation with a 21-year life-of-mine, processing ore from the three deposits through a conventional flotation plant producing four saleable concentrates: pyrite (precious metals bearing), zinc, lead, and copper. The PFS base case assumes long-term metal prices of US$11,470/t copper, US$2,050/t lead, US$2,980/t zinc, US$3,750/oz gold, US$52/oz silver, and US$274/t pyrite concentrate. Total initial capital costs are US$566.7 million, sustaining capital is US$279.5 million, closure costs are US$12.0 million, and total project capital is US$858.2 million. Life-of-mine unit operating costs are US$86.49/t ore processed, with total on-site operating costs of US$2,028 million and total off-site costs of US$886 million. The mine plan is based on a maiden Probable Mineral Reserve of 23.4 million tonnes at 2.30% zinc, 1.13% lead, 0.45% copper, 53 g/t silver, 1.07 g/t gold, and 33.85% sulphur, supporting a 21-year mine life. Plant throughput is 1,200 ktpa, with average annual concentrate production (years 2–19) of 43,489 dmt zinc, 26,120 dmt lead, 10,633 dmt copper, and 694,620 dmt pyrite. The PFS base case yields an after-tax NPV (8%) of US$776 million, IRR of 23.51%, payback period from production commencement of 1 year 11 months, and LOM EBITDA of US$4,559 million. At higher September 2026 spot prices, after-tax NPV (8%) increases to $1,019 million and IRR to 27.13%, with a reduced payback period of 1 year 6 months. An updated Mineral Resource Estimate (MRE) effective July 17, 2026, reports 26.1 million Indicated tonnes grading 2.27% zinc, 1.12% lead, 0.45% copper, 52.0 g/t silver, 1.04 g/t gold, and 33.2% sulphur, plus 9.9 million Inferred tonnes at 2.13% zinc, 1.00% lead, 0.50% copper, 36.0 g/t silver, 0.50 g/t gold, and 22.7% sulphur. NSR cut-off values are US$69.30/t for La Romanera, US$79.20/t for El Cura, and US$85.30/t for La Infanta. The PFS adopts a conventional flowsheet for pyrite concentrate, with pyrite contributing 66% of total NSR. The project benefits from proximity to the Port of Huelva, established transportation, and renewable energy infrastructure. The company notes that permitting, development timelines, and capital requirements remain subject to material risks including environmental approvals, engineering, water management, community engagement, regulatory review, financing, procurement, construction execution, and commodity-market conditions.
