Portugal's Barroso lithium-spodumene project arrived at a London-Lisbon lender syndicate as a shovel-ready FEL-3 file, with an ESIA already cleared by APA and a signed offtake letter of intent covering roughly 60% of Year 1–5 concentrate. The independent technical advisor was asked for a 10-day confirmatory review before a €480m senior tranche vote.

The PERC-coded resource statement looked orderly. When bridged to JORC-equivalent categories for the Australian sub-lender, the Indicated tonnes contracted by 8.4% — the drill-spacing threshold PERC accepts on pegmatite continuity is wider than what the JORC guidance note on lithium deposits considers defensible. On its own, an 8.4% reclassification is not fatal. Layered against the offtake LOI, it is: the 60% coverage assumes the original Indicated tonnage. Re-baselined, coverage rises to 65%, but the Year 6–8 flex tail that anchored the DSCR sensitivity thins by two full turns.

The control point is not the code choice. It is the sequence. A PERC-to-JORC equivalence memo should sit upstream of offtake structuring, not arrive as a lender diligence artefact three weeks before financial close. When equivalence is retrofitted, every downstream number inherits the drift.

Sweden's Norra Kärr heavy rare earth project landed on a Stockholm-London lender syndicate as a FEL-2 to FEL-3 gate review, framed as "European strategic asset, Critical Raw Materials Act eligible." The sponsor deck opened with offtake letters from two EU magnet manufacturers. The technical annex told a different story.

The resource sat on a 2019 PERC-compliant estimate, competent person signed, indicated tonnes stable. The lender syndicate wanted a JORC 2012 equivalence statement for a Toronto co-lender. On paper the two codes are aligned — Table 1 checklists map cleanly. In practice the eudialyte mineralogy carries a metallurgical recovery assumption of 62% on HREE, anchored to a 2016 pilot campaign at 180 kg feed. FEL-3 discipline requires a locked flowsheet with variability testwork across ≥4 domains. The dossier had one domain, one campaign, one recovery curve.

The control point is not the equivalence letter. It is whether the CP will re-sign the recovery assumption under JORC 2012 Clause 49 modifying factors when the flowsheet is not FEL-3 locked. If the answer requires a caveat, the offtake letters — priced on 62% recovery — are no longer bankable in their current form. CRMA eligibility does not substitute for metallurgical variability data.

07/04/2026

A NEC4 Option C target-cost contract for a Zambian copper concentrator upgrade arrived at a London-Johannesburg EPC steering committee marked "pain-share cap negotiated, ready to execute." The 18-month schedule looked disciplined. The pain-share cap sat at 8% above target — tight, but survivable for a sponsor with balance-sheet depth.

The compensation event register told a different story. Twenty-three CEs logged in the first four months of pre-construction, but only eleven had been assessed against the accepted programme under clause 63. The remaining twelve sat in "notified, awaiting quotation" — a status that under NEC4 does not stop the clock, yet the project manager's programme still showed float intact. Float cannot be intact when a third of your CEs are unquantified. Either the programme is wrong, or the register is.

The recommendation was narrow: freeze the target cost adjustment mechanism until every open CE receives a clause 62 quotation within the 3-week statutory window, and require the project manager to reissue the accepted programme with contingency drawn down against each unassessed event. Pain-share caps protect sponsors only when the target cost reflects reality. A cap negotiated against a stale baseline is a cap against a number that no longer exists.

07/04/2026

The GISTM conformance letter arrived at a London-Perth lender syndicate stamped "Level II, no material findings." The independent tailings review board had signed off eleven months earlier. On paper, the upstream-raised TSF at a West African gold operation was tracking the 2025 conformance deadline cleanly. The deposition rate reconciliation told a different story.

Design basis assumed 4.2 Mtpa dry deposition with a beach slope of 1.2%. Actual throughput had drifted to 4.7 Mtpa across the last two wet seasons, and piezometer clusters in the downstream shell showed pore pressure ratios (ru) creeping from 0.24 toward 0.31. Static FoS under GISTM Requirement 4.7 demands ≥1.5 long-term; the recalculated value sat at 1.42. Not a failure state — a calibration state. The upstream raise sequence had been designed against a deposition envelope the operation quietly stopped honoring in month fourteen.

The conformance letter was not wrong. It was answering last year's question. GISTM Requirement 5.1 obliges the Accountable Executive to trigger a design review when operating parameters exceed the design basis by material margins — 12% throughput drift qualifies. The lender's TA memo added one line: refinancing consent conditional on downstream conversion study and revised closure landform to IFC PS3 water-quality thresholds. Conformance is a moving verification, not a filed certificate.

07/03/2026

Chile's Salar de Atacama lithium brine expansion arrived at a London-Santiago battery-precursor lender syndicate as a straightforward reserve-conversion top-up. The sponsor's technical report moved 42% of the incremental resource from indicated to probable, citing 18 months of additional pump-test data and a revised aquifer response model. The DSCR base case sat at 1.68x under a $18,500/t hydroxide deck. On the surface, a clean bankability file.

The divergence surfaced in the IFC PS6 baseline. The sponsor's biodiversity offset ratio was calibrated to a 2019 flamingo census across three Andean salt-flat basins. The lender's independent ESIA reviewer pulled the 2023 CONAF count — Phoenicoparrus andinus down 23%, Phoenicoparrus jamesi down 17% across the same monitoring stations. Under PS6 paragraph 17, critical habitat triggers a net-gain requirement, not no-net-loss. The offset cost delta moved from $14M to $47M, pushing DSCR to 1.41x — inside covenant, outside comfort.

The question is not whether the reserve conversion is defensible. The question is whether a 2019 biodiversity baseline can carry a 22-year mine life through PS6 re-testing at each drawdown milestone. When the baseline drifts faster than the amortisation schedule, the covenant headroom you priced at financial close is not the covenant headroom you'll defend at year seven.

Peru's Moquegua region molybdenum by-product circuit arrived at a London-Lima trading desk as a straightforward toll-treatment renewal. The concentrate assays showed molybdenite recovery holding at 78%, rhenium credits within spec, moisture below the 8% shipment threshold. Contract language pointed to a two-year rollover. On paper, routine — it wasn't.

The toll agreement referenced a 2019 metallurgical baseline: 0.021% Mo head grade, 12.4% concentrate grade, penalty-free below 350 ppm lead. The 2024 shipments were tracking 0.017% head grade with lead at 480–620 ppm across six lots. The producer had absorbed the penalty quietly for eleven months. Under the toll formula's Article 14 escalator, cumulative deductions reached USD 2.3M — small against a USD 180M annual throughput, but the trajectory mattered more than the number.

The question on the desk wasn't whether to renew. It was whether the baseline itself still described the orebody. A toll contract inherits the metallurgy of its reference year; when the mine walks away from that reference, the counterparty carries the drift. Renewal without a re-baselined assay clause and a lead-penalty reopener transfers five years of grade decline onto the treater's book. Escalators are not a substitute for a fresh baseline.

The MRE rebuild lands on the desk with a two-line email: "minor reclassification, no material change." The variogram model tells a different story.

A Western Australian iron-ore satellite deposit came to a Perth-London lender TA review as a routine JORC 2012 update ahead of a USD 340m debt package. Sponsor QP re-domained the pit shell after 14 fresh RC holes, moving 8.2 Mt from Inferred into Indicated. On the summary sheet: recovery unchanged, strip ratio unchanged, LoM +2.1 years. On the block model: the new domain boundary crossed an oxide-fresh transition the previous QP had honoured. Nugget effect on Fe% dropped from 0.31 to 0.08 across the reclassified zone — a variance collapse no additional drilling density can defend at that spacing. NI 43-101 QPs would flag it; CIM guidance is explicit on domain honouring across geometallurgical boundaries.

The DSCR sensitivity ran clean at 1.72x base case. Rebuild the MRE with the original domain constraint and the reclassified tonnage drops to 5.4 Mt Indicated. DSCR at 1.48x. Still bankable — but not at the covenant headroom the term sheet was priced against. The question for the credit committee was never the tonnage. It was whether the QP's re-domaining was a technical judgment or a covenant-driven one.

When the variogram loses variance faster than the drill spacing tightens, the reclassification is not what it says it is.

07/02/2026

Cornwall's St Austell lithium pegmatite extension arrived at a London-Frankfurt battery-precursor lender syndicate as a JORC-to-PERC equivalence exercise. The vendor DD package presented 18 Mt at 0.9% Li2O in the Indicated category under JORC 2012, with a PERC-aligned Competent Person sign-off appended. The bridging memo ran four pages. That was the first control-point failure.

Equivalence between JORC and PERC is not a translation. It is a re-test of drill spacing, QA-QC insertion rates, and geological continuity assumptions against the receiving code's materiality thresholds. The sponsor's memo mapped categories one-to-one and stopped there. On re-review, the pegmatite d**e geometry showed drill spacing at 80m where PERC practice for lithium hosted in narrow structural bodies expects 40-50m for Indicated. Twelve percent of the Indicated tonnage sat on that spacing.

The FEL-3 gate compounded the exposure. Downstream offtake with a German cathode precursor buyer was already drafted at 6,000 tonnes LCE annually, indexed to Fastmarkets. Offtake tonnage anchored to a resource category that would not survive PERC re-classification is not offtake — it is a compensation event waiting for its trigger date.

07/01/2026

Ecuador's Cordillera del Cóndor copper-gold porphyry extension arrived at a London-Toronto stream financier as a mid-cycle upside proposition. The sponsor's technical package showed 312 Mt at 0.61% CuEq with 68% of tonnage in Indicated. The stream term sheet priced off Probable Reserve conversion at 78% — a ratio the sponsor called conservative, drawn from three regional analogues.

The lender-TA calibration disagreed on structural grounds. NI 43-101 conversion from Indicated to Probable requires modifying factors — geotechnical, metallurgical, permit, community — resolved to Feasibility maturity. Two of the three analogues sat in jurisdictions without active IFC PS7 Indigenous consultation processes; Cordillera del Cóndor sits inside Shuar ancestral territory where FPIC documentation was still at community-assembly stage, not final consent instrument. Applying a jurisdiction-adjusted conversion of 61% collapsed the stream NPV8 sensitivity by roughly 22% at flat $4.10/lb copper.

The expectation gap wasn't disagreement on geology. It was disagreement on whether social-licence maturity qualifies as a modifying factor under CIM guidance, or as a parallel risk priced separately. The stream term sheet had folded it into the conversion ratio; the TA held it should sit in a standalone PS7 covenant with drawdown gating. When social licence is priced as geology, the discount rate stops doing its job.
