CADENCE MINERALS PLC (KDNC) — Investment Research Note

Executive summary

Cadence Minerals is an AIM-listed investment holding company whose portfolio is dominated by a 36.2% stake in the pre-production Amapá Iron Ore Project in Brazil, complemented by a 30% carried interest in the Sonora Lithium Project in Mexico (subject to concession-cancellation arbitration). Across 2021–2025 the operating trajectory has been one of protracted development delay, repeated equity dilution and cumulative losses — the Amapá development, first agreed in 2019, remains pre-production with commissioning of the smaller Azteca restart still ahead of it and the larger 5.5Mtpa DR project dependent on further studies, financing and permits 2026-06 annual results. The single most important valuation point today is that the disclosed 100%-basis post-tax NPV of the Amapá DR project (US$1.97bn per the 2024 optimised PFS) attributable to Cadence dwarfs the current £24m market cap by two orders of magnitude — but that gap is only meaningful to the extent a small fraction of the NPV can be realised through construction, financing and licensing that have repeatedly slipped 2025-09 interim; 2026-06 annual results.

Fair value estimate

• Fair value range: 7p – 16p per share (implied market cap ~£29m – ~£66m, mid ~£47m)
• Methodology: Risk-weighted sum-of-the-parts NAV
  • Amapá DR (100% post-tax NPV10 US$1.97bn ≈ £1,550m) × 36.2% × 5–10% risk factor (execution, licensing, financing, dilution): £28m – £56m
  • Azteca near-term restart (380ktpa @ 65% Fe, US$3.5m capex, US$37/dmt FOB; Cadence funded only its US$391k Tranche 1 out of US$4.6m prepayment offtake): risk-adjusted equity value US$5–15m attributable ≈ £4m – £12m
  • Sonora Lithium (30% carried interest, concessions cancelled, non-recourse litigation funding secured post-period for UK–Mexico BIT claim): highly binary, £0 – £5m in a probability-weighted case 2026-06 annual results
  • Central overheads capitalised (~£1.4m/yr admin) and ~£1m net cash offsetting: negative £3m – £5m
• Compared to current £24m market cap: absolute upside to midpoint ~+95%; downside to low end ~+20%. Wide range reflects the binary nature of pre-production mining outcomes.

Sector context

• Sector classification confirmed: Basic Resources / Basic Materials (ICB); specifically a small-cap mining investment vehicle with iron ore, lithium and rare-earth exposure.
• Quality / growth / leverage profile: below typical peers. Cadence is pre-revenue and pre-production, whereas most Basic Resources index constituents are cash-generative miners. Balance sheet is small (£18.6m net assets, £1.06m cash) with a material going-concern uncertainty flagged by PKF Littlejohn 2026-06 annual results.
• Listed peer comparators: Ferrexpo (FXPO) (larger iron-ore producer, low-grade to mid-grade), Champion Iron (CIA) (DR-grade iron ore, producer), Kore Mining/other AIM iron-ore developers. Cadence is closer to a "quoted call option" on Amapá than to any of these.

Investment thesis (3 bullets)

• Deep discount to a credible high-grade iron ore NPV. The 2024 optimised PFS puts the Amapá DR project post-tax NPV at US$1.97bn on a 5.5Mtpa 67.5% Fe concentrate flowsheet — DR-grade material commanding US$15–45/t premia over 62% Fe benchmark — with mining cost reduced 37% to US$11.17/dmt. Even at 5–10% risk-weighting of NPV attributable to Cadence's 36.2%, upside to current cap is substantial 2026-06 annual results; 2025-09 interim.
• Azteca provides a near-term cashflow catalyst funded largely by an offtake partner. Post-period Preliminary Environmental Licence and Installation Licence have been granted, refurbishment is under way, and Cadence's participation is limited to US$391k out of a US$4.6m prepayment facility — a low-capital route to first operating cash flow that (if delivered) materially de-risks the larger DR redevelopment 2026-06 annual results.
• Optionality on the Sonora Lithium arbitration. Non-recourse litigation funding was secured in March 2026 for a UK–Mexico BIT claim following the 2023 concession cancellation. Any successful outcome is asymmetric upside not currently reflected in the equity, and there is no funding drag on shareholders 2026-06 annual results.

Key risks (3 bullets)

• Material going-concern uncertainty and reliance on further equity issuance. The 2025 audit report explicitly flags material uncertainty; the company was pre-production at year-end with £1.06m cash and cost inflation on refurbishment could require additional equity dilution before Azteca cashflow materialises. Shares outstanding rose from ~181m at YE2023 to 415m at YE2025 (plus 12m EBT shares post-period), a >130% increase in two years 2026-06 annual results.
• Repeated timeline slippage — commissioning has moved beyond the earlier end-June 2026 target. The Amapá story has been "just around the corner" since 2019, with the 2022 secured-creditor settlement, licensing, engineering, and now commissioning all pushed back. Historical pattern of guidance misses is documented across every annual report reviewed 2026-06, 2025-06, 2024-06 annual results.
• Sonora is a legal recovery, not an operating asset; concentration on Amapá is near-total. With Sonora concessions cancelled and iron ore prices commodity-cyclical, Cadence is now effectively a single-asset developer whose valuation is highly sensitive to Chinese steel demand, iron ore pricing (currently ~US$100/t range on 62% Fe basis) and Amapá permit compliance 2026-06 annual results.

Operating leverage

Operating leverage here is theoretical rather than empirical because the company has no operating revenue. Cadence itself carries ~£1.1m/yr of admin cost and £0.5m of director/consulting fees against zero revenue — the corporate overhead is essentially all fixed 2026-06 annual results. At the project level, once producing, iron ore mining is a classic high-fixed-cost, high-operating-leverage business: Amapá DR C1 FOB cash costs of US$27.28/dmt against realised prices typically US$80–120/dmt for high-grade product would generate very substantial contribution margin per incremental tonne, with the 15-year LOM post-tax profit of US$4.96bn on 100% basis implying ~US$334m/yr net earnings — Cadence's 36.2% share of that at maturity would be ~US$120m/yr. However, that entire operating-leverage story is contingent on execution: no incremental revenue exists to drop through today. Rating this driver realistically requires distinguishing potential (very high) from realised (nil). I score it at the low-mid end.

Value-trap signals

• Multi-year pattern of missed development milestones (2019 investment agreement, 2022 secured-creditor settlement, 2024 anticipated licences all delayed).
• Persistent equity dilution (share count doubled in FY2025 alone; further 12m EBT shares issued post-period at par).
• Going-concern material uncertainty in auditor's report.
• Single-asset concentration compounded by Sonora write-off risk (loan to REM Mexico of £3.9m potentially impaired if BIT arbitration fails).
• Long-tenure management (Kiran Morzaria CEO since 2015) with limited demonstrable operational track record of bringing an asset into production during that tenure.
• Related-party rental to Gunsynd plc (Don Strang director of both) — small in absolute terms but a governance signal.

Earnings vs. expectations

Cadence has been loss-making in every year reviewed (2021: £0.1m loss, 2022: £5.5m loss, 2023: £3.0m loss, 2024: £3.3m loss, 2025: £1.7m loss). "Guidance" is expressed operationally in milestones rather than financial forecasts, and against those operational milestones the pattern is clear: more misses than meets, and no beats. The 2023 target of licence grants "by end of 2024" slipped; 2024 target of "commissioning by end-June 2026" slipped; 2025 target of trade sale / JV partner for Amapá did not materialise. Management prose has become progressively more hedged, moving from "recommissioning in 2025" (2024 CEO commentary) to "the immediate priority is to complete Azteca refurbishment" (2026 CEO commentary). No analyst consensus is referenced in the filings.

Conviction

Conviction: 2 (low).

Anchors: the underlying PFS numbers on Amapá DR are audited, engineering-grade estimates by internationally accredited consultants, and the market cap–to–NPV gap is so wide that even conservative risk-weightings support the case for undervaluation at current levels; the balance-sheet arithmetic is unambiguous.

Caveats: the valuation depends heavily on execution assumptions (licensing, commissioning, ramp-up, financing) where the track record is poor; the "right" NPV realisation factor could reasonably be anywhere from 3% to 20%, giving a very wide fair-value range; and the single-asset concentration means a discrete negative event (tailings, licence denial, dilutive raise) could permanently impair value.

On fit with the investor profile: this stock has essentially zero AI-receiver exposure — it is a pre-production iron ore junior. It fails the first (35% weight) pillar of the strategy comprehensively. Operating leverage is high in theory but not realisable at current scale. Balance-sheet quality is poor (going concern flag). It is genuinely cheap versus its NAV, which is the one pillar where it scores, but this is a "wrong stock for this strategy" outcome regardless of price.
