Thor Explorations Ltd. (THX.L / THX.V) - Deep Dive Research Report

Report date: 16 May 2026. Four concalls used: Q1 2025 (June 2, 2025), Q2 2025 (August 12-14, 2025), Q3 2025 (November 20, 2025), Q4 2025/FY2025 (April 9-10, 2026). All four are within 12 months of today; the Q4 2025 call is 37 days old.

1. What the Company Does

Thor Explorations is a gold mining and exploration company operating entirely in West Africa. Its business is straightforward: it digs gold out of the ground in Nigeria, sells it, and uses the cash to find and develop more gold elsewhere in the region. What makes it unusual is the geography. Segilola, the company's flagship mine in Osun State, Nigeria, is the first large-scale commercial gold mine ever built in Nigeria - a country with known gold deposits stretching back centuries of artisanal mining but no industrial-scale production until Thor arrived.

The company was steered into this position by Segun Lawson, a Nigerian-British geologist who took the CEO role in August 2011. Lawson trained at the Royal School of Mines at Imperial College London and spent time at Noble & Company (an oil and gas corporate finance house) before pivoting to mining and co-founding African Star Resources. He brought Thor into the Segilola acquisition and led every subsequent financing and construction phase. His background in corporate finance rather than pure geology is visible in how the company is run: there is a strong emphasis on capital discipline, debt retirement, and structured community engagement rather than the pure "drill everything, worry about funding later" mentality common in junior mining.

The Segilola deposit was acquired in 2019. Construction commenced in 2020 with financing from the Africa Finance Corporation, first gold was poured in mid-2021, and commercial production was declared in Q1 2022. That timeline - acquisition to pour in roughly three years - was executed without a single production delay. By the end of 2025, the mine had produced over 350,000 ounces of gold across four full production years.

The technical character of Segilola is central to understanding why it works economically. The deposit sits within the Ilesha schist belt on a major regional shear zone in southwest Nigeria. The gold occurs in a system of stacked, steeply-dipping parallel quartz-pegmatite veins - essentially a series of near-vertical gold-bearing fractures that descend vertically through the rock. The gold is free-milling, meaning it does not require complex chemical processing: it can be liberated from the host rock through straightforward grinding and gravity/cyanide leach recovery. This keeps the process plant relatively simple and allows the recovery rate to run consistently around 93-94%, which is high for a gold mine. The on-site mill processes approximately 230,000-240,000 tonnes of ore per quarter at grades typically between 3.0 and 3.5 grams per tonne.

The company describes itself as targeting "Nigeria's first large-scale commercial gold mine" - that is a factual statement rather than marketing. Nigeria has extensive artisanal gold mining activity but Segilola is genuinely in a category of one for the country.

Beyond Segilola, Thor has two other assets at different development stages. The Douta Gold Project in southeastern Senegal completed its Pre-Feasibility Study in January 2026, demonstrating very strong economics. It is the targeted second mine. In Côte d'Ivoire, Thor holds early-stage exploration licenses covering portions of the same Birimian Greenstone Belt that hosts some of West Africa's largest gold deposits. These are optionality, not near-term cash flow.

2. Business Segments

Thor does not publish formal segment reporting in the conventional sense - all revenue comes from a single producing asset. However, the business is usefully understood through three distinct operating categories: the producing mine (Segilola), the development project (Douta), and the exploration portfolio (Côte d'Ivoire and near-mine Nigeria). Each has different risk profiles, timelines, and strategic roles.

Segilola Gold Mine (Nigeria) - The Cash Engine

Segilola is the entire economic foundation of the company. It generates all current revenue and funds both corporate operations and the exploration pipeline. The mine produced 91,910 ounces in 2025, 85,057 ounces in 2024, 84,609 ounces in 2023, and 98,006 ounces in 2022. The variation is mainly explained by gold grades mined in any given period and the composition of the ore blend.

The mine operates as an open-pit with a conventional crush-grind-gravity-CIL (Carbon-in-Leach) processing circuit. The on-site laboratory, established with MSA Laboratories, conducts fire assay analysis. Mill throughput runs at approximately 950,000 to 970,000 tonnes per year, with recovery rates consistently above 93%. The stockpile of sub-cut-off-grade material (below ~0.8 g/t) has grown to over 50,000 ounces of gold equivalent at current prices, effectively becoming economical ore at gold prices above $3,500 per ounce.

The mine employs 2,125 people as of 2025, of whom 99% are Nigerian nationals and 48% come directly from Osun State, the host state. Procurement spending funnels 86% back into Nigeria. This social footprint is not just ethics - it is the social license to operate in a country where resource nationalism is a perennial concern.

What Segilola knows how to do is sustain high-recovery processing of a high-grade, geologically complex, steeply-dipping vein system in a jurisdiction with limited historical mining infrastructure. The on-site SROL Laboratory, local supply chain development, community development agreements, and a workforce trained from scratch are all competitive advantages that cannot be bought off the shelf. They took years to build.

The mine is now exploring its underground extension. Six drilling rigs are operating beneath the pit, with 21,000 meters drilled to date. Results include 4.2 metres at 12.4 g/t from 295 metres depth, 2 metres at 17.86 g/t from 195.5 metres, and 5.9 metres at 6.0 g/t from 291 metres. The ore body features two structural zones - a Northern Zone with a pronounced southerly plunging shoot and a Southern Zone with four stacked parallel lodes dipping at 60 degrees west. The grade in the underground zone averages 5.5 g/t, meaningfully higher than the open pit average, which is characteristic of the depth extension of this deposit type.

Segilola carries all the current revenue. 2026 guidance of 75,000-85,000 ounces is lower than 2025's actual of 91,910 ounces because the company is mining deeper, lower-grade sections of the open pit while the high-grade underground potential is still being delineated.

Douta Gold Project (Senegal) - The Next Mine

Douta is the company's most advanced development asset and represents the primary source of future production growth. Located in southeastern Senegal's Kedougou region - one of the most prolific gold-bearing areas in West Africa - the project reached a critical milestone with the publication of a Pre-Feasibility Study in January 2026.

The PFS economics are striking at current gold prices. At a base case of $3,500 per ounce, the project generates a pre-tax NPV of $908 million at a 73% IRR. At $4,250 per ounce (roughly current market conditions as of Q1 2026), the pre-tax NPV rises to $1.43 billion at a 102% IRR. The payback period drops to nine months from processing start at the higher price.

The deposit structure is a combination of oxide and fresh (sulphide) ore. The oxide ore is the initial prize: 4 years of production averaging 103,000 ounces per year at an AISC of $1,493 per ounce - cheap to process, high recovery (92.5%), and generating early cash flow. After the oxide ore is exhausted, the mine transitions to processing fresh/primary ore through a suspension roasting circuit - a more capital-intensive process with lower recovery (76-88%) and higher AISC (~$1,890 per ounce). Total mine life is 12.6 years; total production is approximately 1 million ounces from 37 million tonnes milled.

Initial capex of $254 million is planned over an 18-month construction period. Thor reached 100% ownership of the Douta licenses in September 2025 by acquiring Birima Resources' remaining 30% stake for $1.5 million at signing, $3.5 million at the mine decision, and a 1.25% net smelter royalty capped at $7 million. That was an astute transaction - $5 million total cash plus a capped royalty to acquire 30% of a project worth hundreds of millions.

The Environmental and Social Impact Assessment received approval in January 2026. The critical remaining gate is the Mining Convention with the Senegalese government, which sets the fiscal terms (royalties, tax holidays, expatriate quotas) for the mine. Finalizing this document is the gating item for the Final Investment Decision, which management was targeting for H1 2026 but revised to Q3 2026 in the most recent concall.

A 40,000-metre drilling program is underway in 2026 to update the resource, particularly at Baraka 3, Makosa North and East, and in the newly acquired Douta-West permit, with a resource update targeted for Q3 2026.

Thor intends to fund the $254 million capex primarily through project debt (rather than equity), similar to how Segilola was financed through the Africa Finance Corporation. The existing cash position of $154 million (as of Q1 2026) and continuing Segilola cash flows provide a strong equity contribution and negotiating position with lenders.

Côte d'Ivoire Exploration - The Optionality

Thor entered Côte d'Ivoire in 2024, acquiring the Guitry Gold Project from Endeavour Mining for a nominal consideration of $100,000 cash plus a 2% net smelter royalty - the kind of deal that is possible when a major miner is rationalizing its exploration portfolio and a junior buyer can move quickly. The Guitry licenses (773 km²) sit within the Tehini Birimian Greenstone Belt, the same geological formation that hosts Endeavour's Houndé mine (5.2 Moz resource) and Mana mine (2.3 Moz) further north in Burkina Faso. The structural analogy is the key investment thesis: if Guitry contains a scaled-down version of these systems, there is significant resource potential.

Initial RC drilling in Q2 2025 (3,000 metres) returned results including 8 metres at 14.54 g/t from 114 metres depth and 4 metres at 10.68 g/t from 81 metres. A second campaign expanded to 4,604 metres total with additional intersections. These grades and widths are genuinely encouraging for an early-stage exploration program, but they do not yet constitute a resource.

The Marahui permit (250 sq km, northeast Côte d'Ivoire) has returned rock chip results of 19.3 g/t, 10 g/t, and 9.97 g/t gold, again encouraging but pre-resource.

A maiden resource estimate for Guitry was originally targeted by year-end 2025, then Q1 2026, and is now expected in Q2 2026. This repeated slippage is discussed further in the Walk the Talk section.

Thor also holds a Boundiali license in northern Côte d'Ivoire, close to a country border with Mali and Burkina Faso.

3. Products and Business Detail

Thor sells gold. That is the product. But the specifics of how it is extracted, processed, and sold matter for understanding the economics.

Extraction process at Segilola: The open pit uses conventional drill-and-blast mining. Ore is blasted, loaded into haul trucks, and transported to a primary crusher. The crushing and grinding circuit reduces ore to a fine powder (roughly 75-80 microns), which then passes through a gravity circuit to recover the coarsest free gold particles immediately. The remaining slurry goes into a Carbon-in-Leach (CIL) circuit, where sodium cyanide dissolves the remaining gold, which is then adsorbed onto activated carbon. The gold-loaded carbon is stripped, and the gold solution is precipitated onto zinc dust and smelted into dore bars (a gold-silver alloy, typically 85-90% gold). The dore is then shipped to a refinery for final processing to 99.5%+ purity before sale.

The process is designed for free-milling ore - ore where the gold particles are not locked inside refractory minerals like arsenopyrite or pyrrhotite. This is Segilola's advantage: the geology delivers ore that does not require expensive pre-treatment (pressure oxidation, roasting, or bioleaching). Recovery consistently runs 93-94%, meaning for every 100 grams of gold in the rock, 93-94 grams reaches the dore bar.

Daily mining rates exceeded 6,000 tonnes of ore in Q4 2025. The plant processes approximately 8,000-9,000 tonnes per day.

Grade dynamics: Ore grade fluctuates quarter by quarter depending on which sections of the pit are being mined. In Q3 2025, production was 22,600 ounces from 238,000+ tonnes at an implied grade of ~3.0 g/t. In Q4 2025, the grade fell slightly but management compensated by mining more total tonnes (over 6,000 t/day), building a 50,000-ounce stockpile of sub-cut-off material that becomes economic at high gold prices. The 2026 guidance step-down to 75,000-85,000 ounces reflects deeper mining in the pit where grades are lower.

Gold sales: Thor sells gold on spot prices to refineries. It had hedged some production in earlier periods (mentioned in Q1 2025, where management noted "we were able to unwind all our hedged gold positions" - a fortuitous outcome given the gold price rally). The company is now fully unhedged, giving it full upside exposure to spot gold.

Douta processing: The Douta PFS specifies a conventional CIL plant for oxide ore (easy processing, ~92.5% recovery) transitioning to a suspension roasting plant for the fresh/sulphide ore in phase two. Suspension roasting is an established but more complex technology that oxidizes the sulphide minerals before cyanide leaching. It is more capital-intensive and operationally demanding than standard CIL, which is one reason the AISC in the primary ore phase ($1,890/oz) is higher than the oxide phase ($1,493/oz).

Geographical footprint:

• Nigeria (Segilola): 120 km northeast of Lagos, Osun State. Well-connected region with road infrastructure. Mine has developed its own power supply (likely diesel gensets backed by grid connection) and water management systems.
• Senegal (Douta): Southeastern Kedougou region. Remote, requiring its own camp infrastructure and access road construction. The area is gold-prospective but less developed than northern Senegal.
• Côte d'Ivoire: Multiple license areas. Guitry is 220 km west of Abidjan; Marahui is in the northeast near Bondoukou.

Significant milestones:

• 2019: Segilola acquisition
• 2020: Construction starts, Africa Finance Corporation debt secured
• June 2021: First gold pour
• Q1 2022: Commercial production declared
• Q2 2024: Final debt payment to Africa Finance Corporation - debt-free for the first time
• April 2025: Maiden quarterly dividend announced
• September 2025: 100% ownership of Douta achieved
• January 2026: Douta PFS published; ESIA approved

4. Customers

Thor's customer is a gold refinery. Gold is a commodity sold at the spot price quoted on the London Bullion Market Association (LBMA) benchmark. There is no named customer concentration, no switching cost in the conventional sense, and no long-term supply contract in the way an industrial company would have one. The buying decision is made by a refinery treasury function on the basis of dore composition and transport terms. Thor's gold sells immediately to whoever offers the best spot price or under short-term offtake terms.

This is actually a competitive advantage in disguise: gold is the most liquid commodity in the world. There is no customer who can withdraw business, no sales cycle, no qualification requirement, and no renegotiation risk. The company produces gold; the market buys it at whatever the prevailing price is. In Q3 2025, Thor sold 19,650 ounces at $3,535 per ounce. In Q1 2026, it sold 15,417 ounces at $4,829 per ounce.

The risk embedded in this structure is bilateral: there are no customers to lose, but also no fixed-price contracts to protect downside. If gold falls to $1,800 per ounce while AISC sits at $1,100, margins compress to near zero. That risk is addressed in Section 8.

The downstream market for the final refined gold is also worth noting. Gold buyers include central banks (aggregate demand of 863 tonnes in 2025), jewelry manufacturers (weakening at high prices), electronics manufacturers (a small but steady demand component), and investment vehicles (ETFs, bars, coins). None of these end consumers of refined gold have any direct commercial relationship with Thor.

5. Competitive Landscape

In Nigeria: Thor Explorations has no meaningful competition. Segilola is Nigeria's only large-scale commercial gold mine. Artisanal small-scale mining (ASM) is widespread in Nigeria - the Osun, Ekiti, and Kebbi states have long histories of informal gold mining - but ASM operators are not competitors for institutional gold sales or capital allocation. Any future large-scale entrant into Nigerian gold mining would start from exploration stage (several years away from production) and face the same infrastructure challenges Thor navigated during Segilola's construction. This moat is real but temporary - a sufficiently attractive geological discovery near surface could attract a major miner.

In Senegal (Douta competitive context): Senegal's formal gold mining sector is dominated by two operators:

• Endeavour Mining (AIM:EDV): Operates the Sabodala-Massawa complex in eastern Senegal, producing roughly 200,000-220,000 ounces per year. Endeavour is the category-defining West African gold major with over 1.1 million ounces of annual production across multiple countries and a $6.7 billion market capitalisation. Their Massawa deposit (adjacent to original Sabodala) is a high-grade underground system that required substantial investment to bring online.
• Resolute Mining (ASX:RSG): Operates the Mako mine in Senegal, producing roughly 100,000-130,000 ounces per year.

Douta is in the Kedougou region, the same geological province as Sabodala-Massawa. Thor is not competing against these operators for customers (gold is a commodity), but it is competing for capital allocation, labour, government attention, and the perception of Senegal as a mining jurisdiction. The presence of established miners in the region is actually a positive - it validates the Kedougou geological endowment and the regulatory framework.

In Côte d'Ivoire: Endeavour again dominates, with Houndé (Burkina Faso border area) and Ity (western Côte d'Ivoire). Perseus Mining operates Yaouré and Sissingué. Thor's exploration licenses are early-stage and not yet resource-competitive with these established operations.

Peer group for capital markets purposes: Thor is typically benchmarked against AIM-listed junior-to-mid gold producers. Its most direct peers are companies in the 50,000-200,000 oz/year production range operating in West Africa. These include:

• Hummingbird Resources: Previously comparable in scale (Yanfolila, Mali), but is now entangled in Mali government disputes under the new mining code, including a forced 20% stake acquisition by the state - illustrating the difference between operating in stable Senegal/Nigeria versus the Sahel.
• Predictive Discovery (ASX:PDI): Advancing the Bankan project in Guinea - a geological peer but earlier-stage developer.
• Tietto Minerals: Abujar project in Côte d'Ivoire (acquired by Zhaojin Mining).

Thor's competitive advantage within this peer group is:

1. Operational track record - four consecutive years of meeting production guidance
2. Balance sheet strength - $154M cash, zero debt, uniquely positioned for self-funded growth
3. First-mover in Nigeria's gold sector
4. A credible multi-asset development pipeline (Douta is advanced, not speculative)

Barriers to entry for a competitor trying to replicate Segilola in Nigeria are meaningful: the social license took years to build, the regulatory approvals process is complex, the local workforce had to be trained from scratch, and the financing from a multilateral like the Africa Finance Corporation requires a track record and development-finance relationships that cannot be assembled quickly.

6. Industry

Gold as a commodity: Gold is mined, refined, and sold into a global market with constant demand from multiple sources. Unlike most industrial metals, gold does not have a single dominant end-use that links it to any one economic cycle. Jewelry (typically 40-50% of demand) responds to consumer incomes; investment demand (bars, coins, ETFs) responds to inflation expectations, currency risk, and geopolitical uncertainty; central bank demand responds to reserve diversification away from the US dollar; and industrial demand (electronics, medical) is small but steady.

2025 gold market: Total global gold demand (including OTC transactions) exceeded 5,000 tonnes in 2025 - a record. The total value of gold demand reached $555 billion, up 45% year-on-year, driven by the gold price hitting 53 all-time highs during the year. The annual average gold price was $3,431 per ounce, up 44% from 2024. Q4 2025 averaged a record $4,135 per ounce. By Q1 2026, Thor was selling gold at an average of $4,829 per ounce.

Central bank demand reached 863 tonnes in 2025, remaining historically elevated even though it fell short of the exceptional 1,000+ tonne years of 2022-2023. A World Gold Council survey found that 43% of central banks plan to increase gold holdings over the next 12 months - the highest proportion in the survey's eight-year history - suggesting structural demand from this source is not temporary.

ETF inflows of 801 tonnes in 2025 were the second-strongest on record, driven by geopolitical uncertainty, trade tensions, and dollar hedging motives.

West African gold production: West Africa (Ghana, Burkina Faso, Mali, Guinea, Côte d'Ivoire, Senegal) is one of the world's major gold producing regions. Ghana alone represents roughly 47% of regional production. Combined West African output was approximately 10.88 million ounces in 2025, with a projected 8% rebound in 2026 as production normalizes from disruptions. Nigeria historically contributed negligibly to regional production; Segilola represents essentially 100% of Nigeria's formal gold sector output.

Nigeria regulatory context: Gold mining is governed by the Nigerian Minerals and Mining Act (2007) and Regulations (2011). Royalties are charged on an ad valorem basis, currently in the 7.5-15% range. Foreign capital and profit repatriation is permitted in statute. A new Minerals and Mining Bill is undergoing legislative review, with signals of improved investor incentives. The government's Ministry of Solid Minerals Development has articulated a goal of making Nigeria a gold production hub in West Africa, which creates a policy alignment with Thor's expansion ambitions. The risk is the gap between stated policy and implementation.

Senegal regulatory context: Senegal has a more established mining regulatory framework than Nigeria, including a clear Mining Convention negotiation process. The ESIA (Environmental and Social Impact Assessment) approval process functioned predictably for Douta (approved January 2026). The Mining Convention - the specific fiscal terms negotiated between Thor and the government for Douta - is the remaining regulatory gate. Senegal is considered more politically stable than Mali or Burkina Faso, where coups and government-imposed stake acquisitions have disrupted production at foreign-operated mines.

Gold price cyclicality: The gold mining industry is highly cyclical relative to the gold price. When gold prices fall, margins collapse first at high-cost producers. Thor's AISC of $800-1,000 per ounce historically (2024), now guided at $1,000-1,200 for 2026, means the company has historically operated at margins that are comfortable at $2,000+ gold and very lucrative at $3,000-4,000+ gold. At $1,500 gold, the business would be breakeven.

Supply constraints: New gold mine development has become more expensive and time-consuming globally. Rising capex (due to energy costs, equipment costs, and longer permitting timelines), declining grades in established mining districts, and geopolitical risk in emerging markets have all limited new supply growth. This structural supply constraint is a long-term tailwind for gold producers.

7. Growth Triggers

The following triggers are sourced directly from the four concalls used in this report.

Segilola underground resource update: Management has guided for an updated underground mineral resource at Segilola that would convert inferred resource to indicated, potentially demonstrating the viability of an underground mining operation beneath the open pit. Six drilling rigs are operating with 21,000 metres drilled, intersecting zones averaging 5.5 g/t. The resource update has been a repeated target that has slipped, but the drilling data is accumulating. (Mentioned in Q1 2025 concall, June 2, 2025; repeated in Q3 2025, November 20, 2025; as of Q4 2025/FY2025 concall April 9, 2026, timing "remains uncertain" but management expressed confidence in the data quality.)

Douta Pre-Feasibility Study delivered (completed): The Douta PFS was promised in Q2 2025 ("before year-end") and delivered January 26, 2026. Economics confirmed: pre-tax NPV $908 million at $3,500/oz, 73% IRR, 11-month payback at base case gold price. First gold targeted early 2028. (Promised Q2 2025 concall, August 12-14, 2025; delivered Q4 FY2025 period.)

Douta Final Investment Decision (FID):

"We're fully funded, no debt constraints, no requirement to raise external equity." - Management, Q3 2025 concall, November 20, 2025

FID was initially targeted for H1 2026, revised to Q3 2026 in the Q4 2025/FY2025 concall (April 9, 2026). Gating items are: Mining Convention finalization with the Senegalese government, detailed design completion, and EPC contract award. Once FID is made, an 18-month construction period begins.

Douta first gold production: First gold from Douta is targeted for early 2028, with mining operations expected to start end-2027. In the oxide phase, annual production is projected at 103,000 ounces per year - roughly doubling Thor's total gold output from Segilola's current level. (Q4 2025/FY2025 concall, April 9, 2026.)

Segilola stockpile as economic ore: Management noted in Q4 2025 that the 50,000+ ounce stockpile of sub-cut-off grade material (around 0.8 g/t) has become economically viable at current gold prices. This represents additional production potential without incremental mining cost - essentially a free option on high gold prices. (Q4 2025/FY2025 concall, April 9, 2026.)

Guitry maiden resource (Côte d'Ivoire): The Guitry project, acquired for $100K + 2% NSR from Endeavour Mining, sits on the same Birimian Greenstone Belt as Houndé (5.2 Moz) and Mana (2.3 Moz). A maiden resource was targeted by year-end 2025, then Q1 2026, and is now expected in Q2 2026. (Q2 2025 concall: "targeting 500,000-1,000,000 oz maiden resource by year-end"; Q3 2025 concall: "Q1 2026"; Q1 2026 operating update: "results expected Q2 2026.")

Douta resource update: A 40,000-metre drilling program targeting the Makosa, Baraka 3, and Douta-West zones is underway in 2026, with a resource update targeted for Q3 2026. High-grade intercepts at Douta were confirmed in the most recent RNS (May 13, 2026): "High-Grade Exploration Results Confirm Expanding Gold Footprint at the Douta Project." (Q4 2025/FY2025 concall, April 9, 2026.)

Kejola Lawla satellite deposit (Nigeria): A near-mine satellite deposit was flagged for potential mining in 2026 in the Q3 2025 concall (November 20, 2025). This could supplement Segilola ore feed if grades warrant.

8. Key Risks

Mine life uncertainty at Segilola. The original probable reserve of 518,000 ounces at 4.02 g/t was established in the May 2021 Technical Report. After four years of production totalling approximately 360,000 ounces, the residual reserve is depleting. At 80,000 ounces per year, the current stated reserve base represents perhaps 4-5 more years of open pit mining without a successful underground extension. Management's entire mine-life strategy hinges on converting the underground inferred resource (65-76 koz in initial estimates, likely expanded through ongoing drilling) into a commercially viable underground operation. If underground drilling disappoints - either in grade continuity, width, or depth accessibility - the mine's economic life is finite and shorter than the company's growth ambitions require. The resource update has been deferred multiple times, which adds uncertainty to the timeline.

Douta financing and execution risk. The $254 million initial capital requirement for Douta is large relative to Thor's current position. Management intends to use project debt, similar to the Africa Finance Corporation facility used for Segilola. However, the Africa Finance Corporation deal was negotiated when Thor was a much smaller company with a smaller loan requirement. A $150-200 million project loan in 2026 requires lender confidence in the Senegalese fiscal regime, the Mining Convention terms, the construction contractor's capability, and the gold price outlook at the time of drawdown. Any one of these variables could delay or complicate financing. Capex inflation is a real risk: the PFS was prepared at a specific point in time; construction cost inflation in West Africa (driven by energy, steel, and contractor rates) could erode the project economics if FID is delayed.

Senegalese Mining Convention risk. The Mining Convention is a negotiated agreement between a mining company and the Senegalese state that establishes tax rates, royalties, import duty exemptions, and export regulations for the project's life. Thor cannot make an FID without a signed Mining Convention. Negotiations can be protracted, especially if the government is seeking more favourable fiscal terms in a high-gold-price environment. There is precedent in West Africa for governments seeking to renegotiate or impose new terms on developers as commodity prices rise (Mali's new mining code being the most prominent recent example). Senegal's political stability has been better than the Sahel neighbors, but fiscal nationalism is a perennial risk for all mining jurisdictions.

Nigerian regulatory and sovereign risk. Segilola operates under a Mining Lease and a Development Agreement with the Nigerian federal government. Royalties are currently charged ad valorem. A new Minerals and Mining Bill is under legislative review. If royalty rates increase or new taxes are imposed, they flow directly into AISC and compress margins. Currency risk is also present: if the Nigerian naira devalues sharply against the US dollar, local costs (labour, fuel, community obligations paid in naira) become cheaper in dollar terms, but government fiscal pressure to extract more value from resource projects could increase.

Gold price sensitivity. At 2026 AISC guidance of $1,000-1,200 per ounce, the company earns very wide margins at $4,000+ gold. However, the business model's economics are highly sensitive to price. If gold falls to $2,000 per ounce (a scenario that occurred in 2022-2023), AISC of $1,200 would mean margins of $800 per ounce - still profitable but significantly less cash generative, potentially insufficient to fund both Segilola operations and a Douta construction phase simultaneously. At $1,500 gold, the business approaches breakeven. Given that Douta's primary ore phase AISC is $1,890/oz, a gold price environment below $2,000 would make Douta economically unviable in that phase.

Exploration disappointment. The Guitry resource target of 500,000-1,000,000 ounces was described as a maiden resource objective in the Q2 2025 concall. If drilling at Guitry and Marahui fails to deliver a meaningful resource - or delivers a small, low-grade deposit - the optionality narrative collapses and the exploration budget of $30 million (2026 guidance) looks like capital destruction rather than value creation. Junior mining exploration success rates are historically low; most exploration prospects never become mines.

Dilution from option exercise cycles. Share count has been growing incrementally through option exercises. The January 2025 exercise added approximately 8 million net new shares to a base of ~656 million, taking total shares to ~664 million. If further option exercises occur - and option-based compensation is standard for this sector - the existing share count will gradually increase. This is not a crisis risk but is a drag on per-share metrics.

9. Walk the Talk

Concalls used: Q1 2025 (June 2, 2025), Q2 2025 (August 12-14, 2025), Q3 2025 (November 20, 2025), Q4 2025/FY2025 (April 9-10, 2026).

Starting from Q1 2025 (June 2, 2025): Management set several markers for the year ahead. Annual guidance of 85,000-95,000 ounces at AISC of $800-1,000 per ounce was maintained from the FY2024 results. Specific exploration commitments included: completing 12,000 metres of drilling at the Baraka 3 prospect in Senegal during Q2 2025; initiating RC drilling at the Owode target south of Segilola; and planning 2,000 metres of scout drilling at the Ondo project (50 km south of Segilola) in June 2025. Management committed to a Douta PFS completion during 2025. The underground resource update at Segilola was targeted for end-2025.

On the Baraka 3 commitment: the Q2 results confirmed 12,000 metres of drilling was completed and delivered wide, high-grade results (19 metres at 2.46 g/t, 26 metres at 1.31 g/t), validating the exploration investment. Delivered.

On the 2025 production guidance: Full-year 2025 actual production of 91,910 ounces was squarely within the 85,000-95,000 ounce guidance range. The Q3 2025 concall narrowed this to 90,000-95,000 ounces, and the final result came in just under the midpoint. Delivered.

On the Segilola underground resource update: The Q2 2025 concall reiterated "end-2025." The Q3 2025 concall shifted this to "Q1 2026." The Q4 2025/FY2025 concall (April 2026) described six rigs operating and 21,000 metres drilled, but gave no specific timeline for a published resource update. As of April 2026, this commitment has slipped by at least two quarters without a definitive new target. The underlying data (high-grade intersects) supports continued drilling, but the specific resource update promise has been missed and repeatedly deferred.

Moving to Q2 2025 (August 12-14, 2025): Lawson stated:

"We still believe we are a significant value proposition. There is still a lot of upside to come."

The key specific promises were: Douta PFS before year-end 2025; Guitry maiden resource of 500,000-1,000,000 ounces by year-end 2025; and updated Segilola resource by end-2025. Three drilling rigs were commissioned post-period to accelerate exploration.

On Douta PFS: Released January 26, 2026 - technically 26 days after "year-end," but the Q3 2025 concall (November) said it was "imminent, in a matter of weeks." A minor slip, but the content delivered was strong. Largely delivered.

On Guitry maiden resource by year-end: Not delivered. The April 2026 operating update says "results expected Q2 2026." This slipped by at least one full quarter from the original commitment. Not delivered.

On the Segilola resource update: Slipped, as noted above. Not delivered as guided.

Q3 2025 (November 20, 2025) - the most credibility-testing call:

"We delivered another solid, successful, profitable quarter with strong production."

The Q3 call was notable for the Douta PFS being described as "in a matter of weeks" - a statement that proved accurate (released January 26, 2026). The Douta mining license was targeted for Q2 2026; as of the Q1 2026 operating update, the mining convention is still being finalized. The Guitry maiden resource was reset to "Q1 2026" - a target that has since slipped again to Q2 2026. The Segilola underground resource was targeted for Q1 2026 - also not published by April 2026. Management committed to dividends of C$0.0125 per share quarterly; these were paid on schedule through 2025 and a bonus Q4 dividend was declared in January 2026. Dividend commitments: kept.

Q4 2025/FY2025 (April 9-10, 2026): Management guided Q1 2026 production of "20,000+ ounces" - actual was 20,256 ounces. Delivered. Cash was guided at $154 million at Q1-end - confirmed in the operating update. The FID for Douta was pushed explicitly to Q3 2026 from the prior H1 2026 target. Management stated cash would "approach $200 million by year-end 2026," which is a new multi-quarter commitment that will be trackable.

"Our record revenue in Q4 2025 underscores the success of our operational strategy." - CEO Segun Lawson, Q4 2025/FY2025 concall, April 2026

Overall assessment: On production guidance and financial commitments (dividends, debt retirement), this management has a strong and consistent track record - they delivered 91,910 ounces in 2025 against guidance of 85,000-95,000 ounces across every quarter of the year. On exploration timelines - specifically the Segilola underground resource update, the Guitry maiden resource, and the Douta FID - the pattern is consistent slippage of one to two quarters from each stated target. Management is not misleading investors about what they are doing (the drilling is happening, the results are genuinely positive), but exploration timelines are systematically optimistic. Investors who want a hard milestone to hold management accountable should focus on the Douta FID date (currently Q3 2026) and the Guitry resource (currently Q2 2026), knowing both may slip.

10. Shareholder Friendliness Index

Dividends: For the first three years of production (2022 and 2023), no dividend was paid. The company prioritised retiring the Africa Finance Corporation debt and building a cash position. In 2024, after paying the final debt instalment, Thor declared a maiden quarterly dividend of C$0.0125 per share (C$0.05 annualized). The first payment was made May 16, 2025. Throughout 2025, four quarterly dividends were paid, plus a bonus Q4 dividend was declared in January 2026 (the exact amount was not specified in available sources, but total 2025 shareholder returns reached at least $11.9 million by Q3 2025). The policy is explicitly described as "a minimum of C$0.05 per year" with the ability to increase based on cash reserves.

Buybacks and dilution: No share buyback program has been announced or executed as of May 2026. Shares outstanding have gradually increased through option exercises - the January 2025 exercise added approximately 8 million net new shares, taking the count to approximately 664 million. The option plan is the Omnibus Equity Incentive Plan 2022. There is no evidence of a normal course issuer bid being filed. On a net basis, shares outstanding have grown modestly over the period as management and PDMRs vested options, diluting existing holders.

Verdict: Neutral, trending toward Returns Capital. The company initiated a genuine dividend policy upon debt retirement and paid it consistently through 2025 with bonus distributions - shareholder-friendly signals. However, no buyback has been executed, and incremental dilution from option exercises is ongoing. The company is using cash for exploration ($30 million in 2026) and accumulating a war chest ($154 million+) for Douta construction rather than returning it to shareholders.

11. Insider Activities

Listing venue: AIM (London Stock Exchange). Primary source: RNS "Director/PDMR Shareholding" and "Director/PDMR Dealing" announcements via londonstockexchange.com and Investegate.

On the buys: The two open market purchases by Coates (May 2025) and the CFO Chris Omo-Osagie's purchase of 200,000 shares at 38.49p on June 6, 2025 is the most significant signal in this section. Omo-Osagie, as CFO, has the most complete view of the company's financial position, cash generation, and forward trajectory of any executive. He spent approximately £77,000 - roughly doubling his holding to 300,000 shares - in the open market, shortly after the Q1 2025 results showed the company had transitioned decisively to net cash. This is a very bullish signal: the CFO allocated meaningful personal capital at a time when the stock was still trading at a fraction of where the company would later be marked given gold's rally to $4,000+.

The Bed and ISA transfers by Coates (April 2025, February 2026) are tax-optimization events, not conviction signals - the shares move from a dealing account to an ISA account to shelter future capital gains and income from UK taxation. Beneficial ownership does not change.

The January 2025 option exercises are routine - the options were maturing and management exercised them. Most used net settlement (shares surrendered to cover the exercise price rather than paying cash), which minimizes dilution but also means no additional cash was deployed by insiders as a conviction signal.

Net assessment: Insider activity over the past 12 months is modestly bullish. The CFO's open market purchase in June 2025 - the most meaningful signal - came at 38.49p, at a point where the stock's upside to gold's subsequent rally to $4,000+ was not yet priced in. Chairman Coates' genuine purchase in May 2025 adds a second independent data point. The option exercises are routine and should not be read as high-conviction signals. The Bed and ISA transfers are noise. Overall: mild bullish signal, concentrated in two insiders, with no evidence of selling.

12. Scenarios

Bull Case

Gold prices sustain at $4,000-5,000 per ounce through 2026 and 2027, driven by continued central bank demand, dollar weakness, and geopolitical uncertainty. At these prices, Segilola's AISC of $1,000-1,200 per ounce generates cash margins that push the company's net cash position past $200 million before Douta construction starts. The 50,000-ounce sub-cut-off stockpile gets processed, adding incremental production without additional mining cost.

Underground drilling at Segilola delivers a resource update in H2 2026 showing a commercially viable high-grade underground ore body, demonstrating a 3-5 year mine life extension beyond the current open pit plan. This removes the mine-life overhang that is arguably the biggest discount applied to the stock.

The Douta Mining Convention is finalized by July 2026, FID is made in Q3 2026 as guided, and construction starts on schedule. Lenders, encouraged by the PFS economics and current gold prices, provide project financing on favourable terms. Douta's oxide phase production commences in early 2028 at 103,000 ounces per year. Thor transitions from a single-mine producer generating 75-85,000 ounces to a multi-mine operator generating 175,000+ ounces per year.

Guitry delivers a maiden resource of 700,000-1 million ounces, validating Côte d'Ivoire as a third jurisdiction for development. The company is now a credible mid-tier West African gold producer with three countries of exposure, a 12+ year mine life at Douta, and a growing balance sheet.

Base Case

Segilola continues producing 75-85,000 ounces per year through 2026 and 2027. Underground drilling continues but a formal resource update takes until late 2026 or early 2027 to publish, extending the mine life modestly (2-3 additional years). The open pit deepens, grades remain variable, and the 2026 AISC guidance of $1,000-1,200 per ounce proves accurate.

Douta FID slips slightly from Q3 2026 to Q4 2026 or early 2027, as the Mining Convention negotiation proves more protracted than hoped. Construction starts in 2027, first gold comes in 2028 or H1 2029. Capex inflates modestly beyond the $254 million PFS estimate, but within a manageable range. Project financing is secured, with Thor contributing $100-120 million of equity from its balance sheet and borrowing the rest.

Guitry delivers a maiden resource of 300,000-500,000 ounces - smaller than the 500,000-1,000,000 ounce target but enough to confirm Côte d'Ivoire as a viable exploration jurisdiction. Additional drilling is warranted. Thor maintains dividends at the C$0.0125 quarterly level, potentially with modest step-ups if gold prices cooperate.

By late 2027, Thor is a company in transition: Segilola nearing the end of its productive open pit life, Douta in construction, Guitry in continued evaluation. The investment story depends heavily on whether Douta executes on schedule.

Bear Case

The Segilola underground disappoints. Grades thin out at depth, structural complexity increases, and the resource update, when finally published, shows insufficient material for a viable underground operation. The open pit reserve depletes on the existing timeline, and the mine's life is effectively 4-5 years from today. Management's capital allocation dilemma becomes acute: does the company commit $254 million to Douta while Segilola production is declining?

Simultaneously, the Douta Mining Convention stalls. The Senegalese government, emboldened by high gold prices, seeks a larger fiscal take. Negotiations extend into 2027. Construction start slips to 2028. Capital costs inflate due to contractor cost pressure and extended holding costs. Project financing becomes more expensive as lenders price higher political risk. The sub-one-year payback at $3,500/oz remains attractive, but the execution uncertainty creates a prolonged discount.

Gold prices correct to $2,500-2,800 per ounce by 2027, possibly triggered by a US dollar recovery or a reduction in central bank demand. At these prices, Segilola still generates positive cash flow but at greatly reduced margins. Douta's oxide phase ($1,493/oz AISC) remains viable, but the primary ore phase ($1,890/oz AISC) is borderline. Thor enters 2028 with a declining Segilola cash engine, a Douta project still in construction, and an exploration portfolio that has not yet delivered commercial resources.

The company does not fail - its $154 million cash base and no debt provide a cushion - but it transitions from a high-margin compounder story to a capital-intensive developer navigating a tighter environment, and the multi-mine ambition is delayed by 2-3 years relative to current guidance.
