TinOne Drills 14 Metres of 1.03% Tin Within a Near-Surface Intercept of 29 Metres of 0.71% at Its Great Pyramid Project, Tasmania

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: The release explicitly states that RC samples were processed by ALS Limited, an ISO 9001 and ISO/IEC 17025 certified lab, and that control samples (certified reference samples, duplicates, blanks) were systematically inserted.

Compositing Transparentpositive

Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The document clearly states the cut-off grade of 0.1% Sn and maximum consecutive internal waste of 4 metres used for calculating intersections.

Apparent Width Onlynegative

Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that all intersections are downhole widths and true widths are uncertain.

Infill Drillingneutral

Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: The drill program is described as 'confirmatory drilling' with holes designed to 'test and verify the tenor of mineralization returned from the 1970 percussion holes', including 'effectively twins' of older drill holes.

Grade Improvement vs Historicalpositive · Story-specific tag

No canonical definition is currently available.

Why it applies: The release highlights that 'The recent modern Reverse Circulation (" RC ") drilling has returned higher tin grades than the historical open hole percussion drilling' and 'returned significantly higher grades'.

QP/CP Signedpositive

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.

Why it applies: Russell Fulton (MAIG), VP Exploration for TinOne, is named as a Qualified Person and approved the technical information.

Cut-off Disclosedpositive

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The resource table explicitly states a cut-off grade of '> 0.10' Sn %.

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: The mineral resource estimate was prepared 'in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects'.

Inferred Resourcenegative

Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The resource estimate is classified as 'Inferred'.

All Inferrednegative

100% of resource is Inferred category — very early stage, no engineering confidence.

Why it applies: The resource estimate only reports an 'Inferred' classification, with no Measured or Indicated categories.

Maiden Resourceneutral

First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: The document states 'In 2023, a mineral resource estimate (MRE) was prepared' and does not refer to any prior estimates, suggesting this is the first formal MRE for the project.

PEA-Supportingneutral

Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The resource is reported 'within a conceptual pit shell', which is typical for early-stage economic assessments like a PEA.
