Luca Mining Corp. TSXV: LUCA / OTCQX: LUCMF / Frankfurt: Z68
Introduction
Luca Mining Corp. is a Canadian mining company with two 100 percent owned operating mines in Mexico: the Campo Morado polymetallic mine in Guerrero and the Tahuehueto gold-silver mine in Durango. The company produces gold, silver, zinc, copper, and lead, giving Luca a rare mix of precious metals and base metals exposure from existing operations rather than just exploration promises. Luca describes both mines as producing cash flow, with significant development, resource, and exploration upside.
The bull case is simple: Luca is no longer a “maybe one day” developer. It is already producing, already generating revenue, already improving its balance sheet, and now has two operating platforms with brownfield exploration upside. In 2025, revenue increased 103 percent to US$176.8 million, adjusted EBITDA increased 226 percent to US$46.0 million, and net free cash flow before working capital reached US$20.8 million.
The company also made a major balance sheet improvement. Cash increased to US$25.5 million at year-end 2025, and long-term debt was reduced by more than 80 percent to US$3.3 million. By Q1 2026, cash had increased further to approximately US$36.4 million, while remaining debt was about US$1.4 million and expected to be fully repaid by mid-2026.
The strongest upside comes from four things: production growth at both mines, Campo Morado’s potential gold and silver recovery improvement, Tahuehueto’s high-grade near-mine exploration, and the company’s ability to use free cash flow to fund exploration instead of relying heavily on dilution.
The main risk is also clear. Luca must prove that the 2025 turnaround is sustainable. The company has operating mines, but they are underground assets in Mexico with metallurgical complexity, multi-metal revenue exposure, and a history of needing operational improvement. This is not a simple single-asset gold producer. It is a turnaround producer with real upside, but also real execution risk.
Projects / Location / MRE / Grades
Project 1: Campo Morado Mine, Guerrero, Mexico (Flagship Polymetallic Cash-Flow Asset)
| Topic | Details |
| Overview | Campo Morado is Luca’s main polymetallic operating asset. It is located in Guerrero State, Mexico, and covers approximately 121 square kilometres. The mine is an underground VMS-style polymetallic operation producing zinc, copper, gold, silver, and lead. Campo Morado matters because it is not just a small gold mine. It is a multi-metal mine with exposure to zinc, copper, silver, gold, and lead. According to Luca’s February 2026 presentation, 2025 revenue was approximately balanced between precious metals and base metals, with gold at 38 percent, silver 22 percent, zinc 22 percent, copper 16 percent, and lead 2 percent. This gives Luca a more diversified revenue base than many junior producers. If gold and silver rise, Luca benefits. If copper and zinc improve, Luca benefits. The downside is that polymetallic mines are more complex. Recoveries, concentrate quality, treatment charges, payability, smelter terms, and metal price mix all matter. |
| Campo Morado Resource / Grade Feel | Campo Morado has a large existing mineralized system. Luca’s February 2026 presentation lists Campo Morado measured and indicated resources of 16.6 million tonnes grading 4.01 percent zinc, 0.80 percent copper, 0.93 percent lead, 123 g/t silver, and 1.70 g/t gold. The company also summarizes the M&I contained metal as approximately 1.2 billion pounds zinc, 700,000 ounces gold, 0.2 billion pounds copper, 0.3 billion pounds lead, and 62 million ounces silver. Grade feel: Campo Morado is attractive because it is a high-value polymetallic VMS system with meaningful precious metal credits. The gold grade of 1.70 g/t and silver grade of 123 g/t inside a base-metal VMS system are important because previous operators focused more on base metals, while Luca now sees potential to unlock higher-value precious metal zones. |
| Campo Morado Operations | Campo Morado has already shown major operational improvement. Luca states that it turned around Campo Morado, increased throughput to 2,000 tpd, and implemented metallurgical optimizations. For 2025, Campo Morado achieved revised guidance for all metals, producing approximately: • 5,619 oz gold • 736,775 oz silver • 29.1 million lbs zinc • 7.0 million lbs copper The mine remains the company’s most important operating engine because it is larger, more established, and has strong expansion optionality. |
| Campo Morado Expansion Opportunity | The big upside at Campo Morado is not just more tonnes. It is metallurgy and precious metal recovery. Luca is advancing the Campo Morado Expansion study to optimize the mine and increase gold and silver production. The company says cyanidation for gold recovery has never been utilized at Campo Morado, and it is evaluating fine grinding, oxidation, and leaching. Luca expects to outline the impact of Campo Morado 4.0 in an economic study or technical report in 2026, with potential implementation in 2028. This could be a major value driver. If Luca can improve gold and silver recovery without requiring huge new permits or massive capex, Campo Morado may shift from being viewed mainly as a zinc-copper mine with precious metal credits into a more valuable gold-silver polymetallic cash-flow asset. The risk is metallurgical execution. Testing well in the lab is one thing. Producing consistent high-value concentrates and improving recoveries at operating scale is another. |
Project 2: Tahuehueto Mine, Durango, Mexico (New Gold-Silver Producer)
| Topic | Details |
| Overview | Tahuehueto is Luca’s newly constructed underground gold-silver mine in Durango State, Mexico. The property covers more than 100 square kilometres and hosts epithermal gold and silver vein-style mineralization. Luca has successfully commissioned the mill and declared commercial production at Tahuehueto. Tahuehueto is important because it gives Luca a second producing asset and more direct precious metals exposure. Campo Morado is polymetallic and heavily influenced by zinc and copper. Tahuehueto is more gold-silver driven. |
| Tahuehueto Resource / Grade Feel | Luca’s February 2026 presentation lists Tahuehueto global M&I resources of 6.3 million tonnes, containing approximately: • 425,000 oz gold • 9 million oz silver • 36 million lbs copper • 123 million lbs lead • 273 million lbs zinc The company also highlights district-scale potential, with approximately 100 square kilometres of land and 18 veins mapped on the property. Grade feel: Tahuehueto is more attractive than a typical low-grade bulk-tonnage project because it is an underground vein system with higher-grade zones close to existing workings. The project is already built, already producing, and exploration success can potentially feed the mine plan faster than a greenfield discovery. |
| Tahuehueto 2025 Production | For 2025, Tahuehueto delivered: • 15,837 oz gold • 279,997 oz silver • 3.37 million lbs lead • 3.81 million lbs zinc Tahuehueto exceeded the top end of revised guidance for silver and remained within guidance for gold, lead, and zinc. The key point: Tahuehueto is still ramping. This asset can become more meaningful if Luca continues improving throughput, grade control, mining flexibility, and near-mine resource conversion. |
| Tahuehueto Exploration Upside | Recent Tahuehueto drilling is encouraging. In May 2026, Luca reported new assay results from ongoing 2026 drilling, including 6.8 metres of 5.54 g/t AuEq, including 1.0 metre of 22.35 g/t AuEq. Luca also stated that these new breccia zones are close to current mine workings and that portions may be included in resource models and brought into production within one year. That is important because near-mine exploration around an operating underground mine can be highly valuable. New ounces near existing workings can sometimes be cheaper and faster to convert into production than ounces from a remote exploration target. Tahuehueto’s exploration upside comes from the Creston, El Perdido, Santiago, and El Rey systems. Luca has multiple rigs active, and Q1 2026 drilling focused on near-mine and resource expansion targets to extend mine life and improve production flexibility. The risk is that vein systems can be narrow, structurally complex, and sensitive to dilution. High-grade drill intercepts are positive, but the company still needs consistent mineable width, continuity, and grade reconciliation. |
Project 3: Exploration Optionality (Two Operating Mines, Multiple Brownfield Targets)
| Topic | Details |
| Overview | Luca’s exploration story is underrated because the company owns two operating mines with existing infrastructure. This is different from a pure exploration junior that needs to discover, permit, finance, and build everything from scratch. In 2025, Luca restarted exploration across its projects for the first time in more than a decade and completed approximately 30,140 metres of exploration drilling. In Q1 2026 alone, it completed about 10,058 metres of drilling. The company’s three-year exploration program includes a US$25 million budget and supports 80,000 metres of surface and underground drilling at Campo Morado and Tahuehueto, with US$6.5 million budgeted in 2026. Luca also says exploration is fully funded from cash flow. At Campo Morado, Luca has identified 38 priority targets and is using more than 650,000 metres of historical drilling and decades of geologic and geophysical data, including AI-assisted targeting. This is the “hidden optionality” part of the story. Luca is not just trying to keep two mines alive. It is trying to turn two existing mines into larger, longer-life mining camps. |
Share Structure / Ownership / Insiders
| Section | Details |
| Capital Structure | As of April 16, 2026, Luca reported: • Shares outstanding: 275,143,153 • Options: 14,782,501 • Warrants: 0 • RSUs: 1,400,000 • Fully diluted shares: 291,325,654 This is a fairly clean structure for a junior producer, especially because warrants were reduced to zero after significant exercises. Using a TSXV share price of approximately C$1.36 and the fully diluted share count of 291,325,654, Luca’s fully diluted market capitalization is approximately C$396.2 million, or about US$288.7 million using a CAD/USD rate near 0.7286. |
| Share Structure Feel | Luca’s share structure is not ultra-tight, but it is reasonable for a two-mine producer. The company also improved the structure by eliminating warrants, which removes a major overhang. The most interesting development is the planned normal course issuer bid. In May 2026, Luca announced its intention to repurchase up to 13.75 million common shares, representing approximately 5 percent of outstanding shares, for cancellation. The NCIB is expected to run from May 21, 2026 to May 20, 2027. That is a strong signal. Many juniors constantly issue shares. Luca is now talking about buying back shares. If the company follows through using free cash flow, that would be a major positive for share structure discipline. |
| Ownership / Insiders | Luca’s February 2026 presentation shows the shareholder base as: • 15 percent insiders • 21 percent close management-associated • 8 percent institutions • 56 percent public float This is good alignment. Insiders and close management-associated holders together represent roughly 36 percent of the shareholder base. Yahoo Finance also shows insider ownership around 14.95 percent and institutional ownership around 7.30 percent. Ownership feel: Strong. The insider and close-associated ownership is meaningful enough to suggest management is aligned, but the public float is still large enough for liquidity. |
People / Management
| Person | Role | Details / Management Feel |
| Dan Barnholden | Chief Executive Officer | Dan Barnholden became CEO in July 2024. He has more than 20 years of experience in senior mining investment banking roles at bank-owned and boutique dealers in Toronto and Vancouver. He has raised billions of dollars in debt and equity for junior, mid-tier, and senior mining companies and has advised companies on mergers, acquisitions, divestitures, and strategic matters. Management feel: Barnholden is highly relevant for Luca’s current stage. Luca needed balance sheet repair, operational discipline, capital markets credibility, and a growth plan. Since he joined, Luca has reduced debt sharply, increased cash, improved operations, and started positioning itself as a rerating story. |
| Ramon Perez | President | Ramon Perez has more than 15 years of international mining experience, including 10 years as VP of the Carrelton Horizon Natural Resource Fund, where he covered metals and mining companies in Latin America. He is also a founding member of Sociedad Minera Reliquias S.A., now listed on the TSXV as Silver Mountain Resources. Management feel: Perez adds Latin America mining experience and public market experience. This matters because Luca is operating in Mexico and may also evaluate M&A opportunities. |
| Ramon Mendoza | COO & CTO | Ramon Mendoza has more than 35 years of senior mining industry experience, including mine development, mine process improvement, and managing both underground and open-pit operations. He specializes in optimization, mine design, planning, cost modelling, and integrating geoscience into mine plans. Management feel: Mendoza is one of the most important people operationally. Luca’s upside depends on execution at Campo Morado and Tahuehueto. This is where mine planning, process improvement, and cost control matter. |
| Paul Gray | VP Exploration | Paul Gray has more than 30 years of global precious and base metals exploration experience. His background includes multi-million-dollar exploration programs, resource delineation, and NI 43-101 technical report authorship. Management feel: Gray is important because Luca is now funding a major brownfield exploration program. The company needs to turn exploration spending into mineable ounces, not just good-looking drill results. |
| Lisa Dea | Chief Financial Officer | Lisa Dea has more than three decades of finance, securities, and accounting experience. She was previously CFO of Guanajuato Silver and played a role in reactivating past-producing silver and gold mines in central Mexico. Management feel: Strong fit. Luca is a producing Mexico-focused company, and Dea has relevant experience with mine reactivation and public mining company finance. |
| Peter Damouni | Chairman | Peter Damouni has over 20 years of corporate and investment banking experience focused on natural resources. He has been involved in equity and debt financings, restructurings, joint ventures, acquisitions, and sale processes. Management feel: Damouni adds capital markets and corporate strategy experience. This is useful because Luca may pursue M&A and needs to manage capital allocation carefully. |
| Phil Brumit | Director | Phil Brumit has over 40 years of mining experience in property evaluation, engineering, project management, construction, start-up, and operations. He previously served as Executive VP Projects & Operations at Josemaria Resources and was President and Managing Director of Minera Candelaria, a Lundin Mining subsidiary. Management feel: Very relevant. Brumit brings real mine operating and project experience, which is exactly what a two-mine producer needs. |
Risks / Catalysts / Timeline
| Key Risk | Why It Matters |
| Operational risk | Luca owns two underground mines. Mine sequencing, dilution, grade reconciliation, equipment availability, labour, and contractor execution all matter. |
| Metallurgical risk | Campo Morado is a complex polymetallic VMS operation. Recovery improvements and precious metal optimization must work at operating scale. |
| Commodity price risk | Luca is exposed to gold, silver, zinc, copper, and lead. This is a strength when metal prices rise, but a risk when base metals weaken. |
| Mexico jurisdiction risk | Both mines are in Mexico. Mining policy, security, community relations, taxes, labour rules, permitting, and regulatory changes can affect operations. |
| No feasibility-study risk at Campo Morado | Luca’s presentation cautions that commercial production at Campo Morado was declared without a feasibility study of mineral reserves demonstrating economic and technical viability. |
| Tahuehueto ramp-up risk | Tahuehueto is newly in commercial production. It still needs to prove consistent long-term throughput, cost control, recoveries, and grade performance. |
| Exploration conversion risk | High-grade drill results are positive, but they must convert into resources, reserves, mine plans, and profitable production. |
| Cost inflation risk | Underground mining, reagents, labour, energy, consumables, and sustaining capital can pressure margins. |
| Concentrate treatment and payability risk | Polymetallic concentrate economics depend on smelter terms, penalties, recoveries, and metal payability. |
| Capital allocation risk | The company is considering exploration, optimization, buybacks, debt repayment, and M&A. Poor capital allocation could hurt shareholder value. |
| Catalyst / Timing | Details |
| 2026 | full repayment of remaining debt expected by mid-year |
| 2026 | continued production growth from both operating mines |
| 2026 | Campo Morado Expansion technical report expected in H2 2026 |
| 2026 | ongoing Tahuehueto drilling and near-mine resource conversion |
| 2026 | continued Campo Morado gold-silver exploration results |
| 2026–2027 | potential share buybacks under NCIB |
| 2026–2028 | potential Campo Morado recovery improvement studies and implementation |
| 2027 and beyond | production growth toward Luca’s long-term 200,000+ oz AuEq ambition |
| Medium term | potential rerating from small producer to Mexico-focused mid-tier producer |
| Luca’s corporate presentation states that the company is targeting 200,000+ oz AuEq production through organic growth and M&A over the longer term. |
| Period | Expected Progress |
| 2025 | This was the turnaround year. Luca achieved revised guidance for all metals, increased revenue to US$176.8 million, generated US$46.0 million adjusted EBITDA, improved cash, reduced debt, and restarted meaningful exploration. |
| 2026 | This is the proof year. Luca needs to show that 2025 was not a one-off improvement. The key focus areas are debt elimination, operating consistency, production growth, Campo Morado Expansion study work, and exploration conversion at both mines. By March 31, 2026, cash had increased to US$36.4 million and debt had fallen to about US$1.4 million. Management stated that the company remains focused on operational improvements at both mines, especially Campo Morado as the Campo Morado Expansion study advances toward a technical report in H2 2026. |
| 2027 | The market will likely focus on whether Luca can sustain stronger production, improve margins, and start proving that the exploration program is adding mine life and production flexibility. If the NCIB is active and free cash flow remains strong, share buybacks may also become part of the rerating story. |
| 2028 onward | Potential implementation of Campo Morado processing improvements could become a major growth driver. If gold and silver recoveries improve materially, Luca may become a much more precious-metals-driven producer. Longer term, Luca wants to move toward mid-tier producer ranking through organic growth and M&A. |
Valuation Summary
This is a simplified valuation model. It uses Luca’s 2025 adjusted EBITDA of US$46.0 million and 2025 net free cash flow before working capital of US$20.8 million as base figures. It does not adjust for taxes, sustaining capital changes, metal price changes, working capital, future dilution, mine depletion, exploration success, M&A, or changes in production levels.
Share count used: 275,143,153 basic shares outstanding as of April 16, 2026.
FX used: CAD/USD 0.7286.
Current reference price used: approximately C$1.36.
Base Case – 2025 Adjusted EBITDA Model
2025 adjusted EBITDA: US$46.0 million
Valuation at 10× EBITDA:
US$460 million market value
US$1.67/share
Approximately C$2.29/share
Valuation at 15× EBITDA:
US$690 million market value
US$2.51/share
Approximately C$3.44/share
Valuation at 20× EBITDA:
US$920 million market value
US$3.34/share
Approximately C$4.59/share
This model gives Luca meaningful upside from the current C$1.36 reference price if the market values the company as a growing, debt-free, multi-asset producer instead of a small turnaround story.
Base Case – 2025 Free Cash Flow Model
2025 net free cash flow before working capital: US$20.8 million
Valuation at 10× FCF:
US$208 million market value
US$0.76/share
Approximately C$1.04/share
Valuation at 15× FCF:
US$312 million market value
US$1.13/share
Approximately C$1.56/share
Valuation at 20× FCF:
US$416 million market value
US$1.51/share
Approximately C$2.08/share
This model is more conservative than the EBITDA model because 2025 included elevated sustaining capital and exploration spending. If Luca can grow production while controlling sustaining capital, free cash flow could improve materially.
Upside Case – US$60M Adjusted EBITDA Scenario
If Luca grows adjusted EBITDA to US$60 million:
• 10× EBITDA = approximately C$2.99/share
• 15× EBITDA = approximately C$4.49/share
• 20× EBITDA = approximately C$5.99/share
This scenario assumes Luca continues improving production and margins, but does not require the company to hit its long-term 200,000+ oz AuEq ambition.
Bull Case – US$80M Adjusted EBITDA Scenario
If Luca grows adjusted EBITDA to US$80 million:
• 10× EBITDA = approximately C$3.99/share
• 15× EBITDA = approximately C$5.99/share
• 20× EBITDA = approximately C$7.98/share
This is the rerating case. It likely requires stronger production, better precious metal exposure, improved Campo Morado recoveries, stable Tahuehueto performance, and strong metal prices.

RT Rating, Commentary
Luca Mining is on our watchlist.
We rate this as 5 out of 5 stars.
Luca ticks many of the important boxes: it is already producing, has two operating mines, has real revenue, has improved its balance sheet, has strong insider alignment, has no warrants, and may even start buying back shares. That is not common in the junior mining sector.
The main downside are operational proof and location. Luca still needs to show that 2025 was not just a turnaround year, but the beginning of a sustainable growth cycle. Campo Morado needs to prove better precious metal recovery, Tahuehueto needs to prove consistent ramp-up performance, and exploration needs to convert into mineable ounces.
The upside is attractive because the market may still be valuing Luca like a small turnaround producer. If the company becomes debt-free, sustains free cash flow, improves Campo Morado recoveries, grows Tahuehueto, and executes buybacks, Luca could rerate sharply.
