ANALYST NOTE: FSM (Fortuna Mining Corp.) Date: 2026-06-13 Current Price: $9.26

1. Structural Readiness

Conservative Entry: Not yet defined (awaiting confirmed breakout) Aggressive/Pre-Breakout Entry: Current price ($9.26) represents a potential entry into a forming structure, provided the price holds above the support line. Breakout Level: Not yet triggered. Extension: Not applicable (price has not extended from a confirmed breakout). ATR Context: Current ATR is 5.5% (High). This indicates elevated volatility, which is consistent with a "High" volatility bucket (4–6% historical sweet spot). This suggests that while the setup is forming, the price action is energetic, requiring careful position sizing to account for the wider stop distances inherent in this volatility profile.

2. Thesis Layer

Thesis Classification: Tactical / Setup-Led Macro Thesis Status: None. Analysis: As of 2026-06-13, there is no named secular thesis attached to this name. The investment case is strictly tactical, driven by the quality of the technical setup (the forming coil) and the immediate business fundamentals disclosed in recent earnings. We are judging this name on its structural readiness and operational execution rather than a broad macro theme.

3. Business Overview

Company Profile: Fortuna Silver Mines Inc. is a precious and base metals producer with a diversified portfolio of operating mines and development projects. Operations & Portfolio:

• Caylloma Mine (Peru): Produces silver, lead, and zinc.
• San Jose Mine (Mexico): Produces silver and gold.
• Lindero Project (Argentina): Gold project.
• Yaramoko Mine (Burkina Faso): Gold mine.
• Séguéla Mine (Côte d'Ivoire): Gold mine, currently undergoing expansion.
• Diamba Sud Project (Senegal): Gold project, currently in the final stages of permitting and feasibility.

Operational Highlights (Source: Earnings Transcript, 2026-05-07):

• Production Guidance: Management expects to deliver approximately 60% growth in annual gold production over the next 24 months, targeting approximately 0.5 million ounces of annual gold production. This growth is driven by the expansion of the Séguéla mine and the ramp-up of the Diamba Sud project.
• Feasibility & Permitting: Both the Diamba Sud feasibility study and the Séguéla expansion study were expected to be completed in May 2026, providing technical and economic visibility. Management stated they are expecting environmental approval for Diamba Sud "imminently," followed by the final mining permit shortly thereafter.
• Reserves & Resources: Proven and probable mineral reserves increased by 50% year-over-year (after depletion) to 3 million gold ounces. Indicated mineral resources increased by 56% to 2.1 million gold ounces.
• Cost Profile: Management expects All-In Sustaining Costs (AISC) to move toward $1,300 per ounce by the fourth quarter of 2026.
• Capital Return: Year-to-date, the company returned $40 million to shareholders via the repurchase of 4.2 million shares.
• 2026 Performance: The company produced 72,900 gold equivalent ounces in the quarter and remains well-positioned to meet its full-year 2026 guidance.

4. Archetype and Conviction

Archetype: Margin Inflector Rationale: The company fits the "Margin Inflector" archetype due to the combination of significant reserve growth (50% increase in P&P reserves) and a clear path to cost reduction (AISC targeting $1,300/oz) alongside production expansion. The completion of feasibility studies for Diamba Sud and Séguéla expansion provides the structural leverage to improve margins as production scales.

Valuation & Financial Spine:

• Forward Consensus: FY1 EPS consensus is $1.6044; FY2 EPS consensus is $1.65258.
• Economic Robustness: Management notes that the new projects demonstrate robust economics at long-term gold prices below $3,000 per ounce.

Conviction Stack:

• Thesis Strength: Moderate (Tactical, no macro tailwinds).
• Evidence Quality: High. Recent earnings (May 2026) provide specific, quantified guidance on production, costs, and permitting.
• Structural Quality: Strong. The reserve growth and cost trajectory support the "Margin Inflector" label.
• Rerating Potential: Moderate to High, contingent on the successful execution of the Diamba Sud permitting and the realization of the 60% production growth target.

5. Invalidations, Strengtheners, and Gaps

Invalidation Triggers:

• Fundamental: Failure to secure the "imminent" environmental approval for Diamba Sud or a significant delay in the final mining permit would undermine the 2026-2028 growth thesis.
• Operational: A significant miss on the full-year 2026 guidance or a failure to achieve the $1,300 AISC target would weaken the margin inflector thesis.

Strengtheners:

• Technical: A confirmed breakout above the current resistance levels with volume.
• Fundamental: Confirmation of the Diamba Sud environmental approval and the start of construction, or an upward revision to the 2026 production guidance.

Gaps in Evidence:

• Specific Permit Dates: While "imminent" approval is stated, no specific calendar date for the environmental permit is provided in the evidence.
• Capex Details: The specific capital expenditure required to fund the expansion and the funding mix (debt vs. equity) is not detailed in the provided snippets.
• Silver/Lead/Zinc Exposure: While the portfolio includes silver and base metals, the specific sensitivity of the 2026 guidance to non-gold metal prices is not quantified in the provided text.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: medium Key evidence: 50% YoY increase in proven and probable reserves to 3M oz; Management guidance for 60% gold production growth over 24 months; Feasibility studies for Diamba Sud and Seguela expansion completed in May 2026; AISC expected to decline to $1,300/oz by Q4 2026. Key risks: Delay in environmental or mining permits for Diamba Sud; Execution risk on the 60% production growth target; Volatility in gold prices impacting project economics; High current ATR (5.5%) indicating elevated price risk. Sizing hint: Position size should account for the 5.5% ATR volatility; consider scaling in as the forming coil resolves to a confirmed breakout. Expected path: Management executes on the Diamba Sud permitting and Seguela expansion, driving production toward the 0.5M oz target and AISC toward $1,300/oz, with the stock resolving the forming coil structure upward. Expected horizon: 12 to 24 months for the full realization of the production growth thesis.
