# Atlas tag definitions

- **Bonanza Intercept:** Exceptionally high-grade zone, well above the deposit-type norm.
- **Metal Equivalent Opaque:** Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.
- **True Width Disclosed:** Actual thickness perpendicular to structure is stated, not just downhole length.
- **Apparent Width Only:** Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.
- **QA/QC Disclosed:** Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
- **Compositing Transparent:** Cut-off grade and internal dilution rules are clearly stated for reported intervals.
- **No QA/QC Disclosure:** Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.
- **Cut-off Undisclosed:** Cut-off grade not disclosed — cannot assess comparability to prior estimates or peers.
- **Step-Out Extension:** Mineralization extended beyond the previously known limit.
- **Infill Drilling:** Confirmatory drilling to raise resource confidence, not new discovery.
- **Stale Data Re-release:** Historical results re-announced with no new assays or reinterpretation — low genuine novelty.
- **Deleterious Elements Present:** A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent.
- **Refractory Ore:** Complex mineralogy requiring oxidation or other special processing before recovery.
- **Nearology Play:** Value premise rests on proximity to a known deposit rather than own results.
- **Measured Resource:** Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.
- **Indicated Resource:** Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
- **Proven Reserve:** Measured Resource with demonstrated economic viability after applying modifying factors.
- **Probable Reserve:** Indicated Resource with demonstrated economic viability after applying modifying factors.
- **Inferred Resource:** Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
- **All Inferred:** M&I share below the weak bound — very early stage, no engineering confidence.
- **Tonnage Growth:** Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.
- **Grade Improvement:** Average resource grade improved vs prior estimate — better deposit economics.
- **Contained Metal Growth:** True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.
- **Category Upgrade:** Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.
- **Tonnage Decline:** Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down.
- **Grade Decline:** Average grade fell below the red-flag bound vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling.
- **Contained Metal Decline:** Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.
- **Category Downgrade:** Resource confidence decreased — Measured downgraded to Indicated, or Indicated to Inferred. Unusual and concerning.
- **Dilutive Growth:** Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion.
- **Cut-off Lowered:** Cut-off grade reduced beyond the suspicious bound vs prior estimate — tonnage growth may be artificial inflation.
- **Cut-off Undisclosed:** Cut-off grade not disclosed — cannot assess comparability to prior estimates or peers.
- **Stale Estimate:** Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
- **QP/CP Signed:** Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
- **Cut-off Disclosed:** Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
- **JORC Compliant:** Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
- **NI 43-101 Compliant:** Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
- **Historical Estimate Only:** Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.
- **No Contained Metal:** Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.
- **No QP/CP Disclosure:** No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.
- **Maiden Resource:** First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable.
- **Resource Update:** Revised estimate for an existing resource — compare to prior to assess progress.
- **PEA-Supporting:** Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
- **PFS-Supporting:** Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.
- **DFS-Supporting:** Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.
- **High Recovery:** Recovery at or above the exceptional band for the commodity and processing route.
- **Pilot Scale Complete:** Pilot or demonstration plant testing completed under continuous operation.
- **Free Milling:** Simple, clean ore amenable to standard processing without oxidation.
- **Multi-Domain Tested:** Variability across ore domains (oxide, transition, fresh) has been addressed.
- **Recovery Improving:** Recovery improved versus a like-for-like prior test program on the same domain and route.
- **Low Recovery:** Recovery below the weak band for the commodity and processing route.
- **Bench Scale Only:** Only preliminary bench tests completed — no locked-cycle or pilot work.
- **Refractory Ore:** Complex mineralogy requiring oxidation or other special processing before recovery.
- **Single Domain Only:** Testing limited to one composite or domain — representativeness not established.
- **Recovery Stagnant:** No improvement across multiple test programs on comparable material.
- **Theoretical Recovery Only:** Only theoretical or liberation-derived recovery reported, with no actual test result.
- **Heap Leach Route:** Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
- **Mill Route:** Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
- **Gravity Route:** Gravity separation forms a material part of the flowsheet.
- **POX/BIOX Route:** Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.
- **Byproduct Commodity:** The tested commodity is a byproduct rather than the primary economic driver.
- **DFS Bankable:** AACE Class 2-1 study complete and within the staleness window.
- **PFS Complete:** AACE Class 3 study complete.
- **PEA Only:** Only Class 4 / Initial Assessment economics available. Not bankable.
- **No Study:** No formal economic study — no engineering basis for the economics quoted.
- **Stale Study:** Beyond the staleness window measured from the estimate base date.
- **Inferred Heavy Feed:** Material Inferred share of LOM mill feed, or the share is undisclosed.
- **Resource Governance Undisclosed:** No QA/QC, top-cut methodology or QP independence disclosed. Caps study quality at the moderate tier.
- **NPV Cut vs Prior Study:** A restated study reduces NPV materially against its own predecessor on the same asset.
- **High IRR:** Post-tax real unlevered IRR in the strong tier or better.
- **Low IRR:** IRR below the moderate tier.
- **Below Jurisdiction Hurdle:** IRR below the greenfield or brownfield hurdle for its jurisdiction tier.
- **IRR Basis Undisclosed:** Real vs nominal not stated, so the tier is not comparable across studies.
- **Undervalued PNAV:** Funding-adjusted P/NAV in the strong tier or better.
- **Overvalued PNAV:** Funding-adjusted P/NAV in the red-flag tier.
- **Fast Payback:** Payback in the strong tier or better, on the required basis.
- **Slow Payback:** Payback in the weak tier or worse.
- **Bottom Quartile Cost:** P0-25 of the relevant commodity cost curve.
- **Top Quartile Cost:** P75-100 of the relevant commodity cost curve — first to cut in a downturn.
- **Cost Basis Undisclosed:** By-product vs co-product not stated, so quartile placement is unreliable.
- **Low Capital Intensity:** Below the benchmark for its project type.
- **High Capital Intensity:** Above the benchmark for its project type.
- **Conservative Pricing:** Conservative on the worst of the spot, 3-year and consensus comparisons.
- **Aggressive Pricing:** The study only works on a stretched price deck.
- **No Price Sensitivity:** No price sensitivity disclosed — treated as a deliberate signal, not a neutral gap.
- **No Discount Rate Sensitivity:** Blocks NPV normalisation to the common rate without reconstruction.
- **Price Deck Unstructured:** Prices given only as free text, so conservatism cannot be scored.
- **Long Reserve Life:** Reserve life index in the top tier of the single ladder.
- **Short Reserve Life:** Reserve life index in the critical tier.
- **Resource Life Upside:** Wide gap between reserve life and resource life — conversion upside rather than discovery dependence.
- **Fully Funded:** Funding coverage at or above 1.0x counting committed facilities only.
- **Material Funding Gap:** Funding coverage below the substantially-funded band.
- **Funding Gap Exceeds Market Cap:** Red flag regardless of headline NPV — the upside is not reachable by the current equity holder.
- **Encumbered by Stream:** An existing stream or royalty reduces attributable NAV and restricts future financing.
- **Stability Agreement:** Fiscal terms fixed, with a term covering the mine life.
- **High Government Take:** Total government take above the regional norm as a share of pre-tax cash flow.
- **Fully Permitted:** Key permits granted with no unresolved challenge.
- **Permit Challenge Outstanding:** An appeal or legal challenge is unresolved, which can defer first production indefinitely.
