Summary

TG Metals Ltd has released positive Scoping Study results for its Van Uden Gold Project in Western Australia, outlining a low-capex, near-term heap leaching opportunity for its at-surface laterite gold material. The study projects robust financial metrics, including a pre-tax NPV8 of A$26.8 million and an IRR of 121%, based on processing 250,000 tonnes per annum over a three-year mine life with 90% gold recovery. While the study highlights significant potential, it is a preliminary assessment with cautionary statements regarding its accuracy, reliance on Inferred resources, and a high gold price assumption of US$4,400/oz.

Reasoning: The Scoping Study outlines positive preliminary economics for a low-capex heap leach operation at Van Uden, supported by a high-confidence laterite resource and good recoveries, but it is an early-stage study with significant cautionary statements and a very high gold price assumption.

Positive factors

  • Positive financial metrics (NPV, IRR, payback)
  • Low pre-production capital cost
  • High gold recovery (90% adopted)
  • Laterite material is at-surface and low-cost
  • High percentage of Indicated resources in the laterite MRE (89.8%)
  • JORC 2012 compliant resource estimate
  • Slight increase in total MRE tonnage

Negative factors

  • Scoping Study level of accuracy (preliminary, not sufficient for Ore Reserves)
  • High gold price assumption (US$4,400/oz) used in financial model
  • Reliance on Inferred resources (15% of mine plan, though stated not material to viability)
  • Funding required (A$15 million) with no certainty of non-dilutive financing
  • Metallurgical testwork results are preliminary (residue not analyzed, one column ongoing)
  • No Ore Reserve declared

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 4

Classification and evidence

JORC Compliantpositive

Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.

Why it applies: The Mineral Resource Estimate is reported in accordance with The JORC Code (2012 Edition).

Evidence · text

“The MRE for the Van Uden Gold Project is reported in accordance with The JORC Code (2012 Edition)”

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: Mr Lynn Widenbar, a Competent Person, compiled the Mineral Resources information, and Mr Michael Rodriguez, a Competent Person, compiled the metallurgical results.

Evidence · text

“The information in this report that relates to Mineral Resources is based on information compiled by Mr Lynn Widenbar, a Competent Person... Information in this announcement that relates to metallurgical results, is based on information compiled by Mr Michael Rodriguez who is a Fellow of the Australasian Institute of Mining and Metallurgy and a Engineering Metallurgical consultant.”

Maiden Resourceneutral

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

Why it applies: The document refers to the 'current gold bearing laterite Mineral Resource Estimate' and discusses its growth potential, implying it's a relatively new estimate for this specific laterite material.

Evidence · text

“The current gold bearing laterite Mineral Resource Estimate (MRE)2 contains ~1.1Mt @ 0.52g/t Au for 17,700oz of gold, with significant opportunity to grow the laterite Resource.”

Tonnage Growthpositive

Significant tonnage increase (≥15%) vs prior estimate with grade maintained or improved.

Why it applies: The current MRE of 1.1Mt is a slight increase from the prior RAG estimate of 1.053Mt.

Evidence · text

“The current gold bearing laterite Mineral Resource Estimate (MRE)2 contains ~1.1Mt @ 0.52g/t Au for 17,700oz of gold”

Heap Leach Routeneutral

Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: The Scoping Study is based on a heap leaching production opportunity for the laterite material.

Evidence · text

“At-surface, gold-bearing laterite material assessed as a potential low-cost, near term heap leaching production opportunity at the Van Uden Gold Project”

High Recoverypositive

Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: The column leach tests achieved recoveries of +95% and 81.3%, with 90% adopted for the study financials, which is strong for a heap leach operation.

Evidence · text

“Estimated gold extractions for each column are: +95% for LAT Column, 4m height, leach completed. +95% for TAS Column, 4m height, leach completed. 81.3% for DBS Column, 2m height, leaching ongoing. Hence a 90% recovery has been adopted for the study financials.”

Pilot Scale Completepositive

Pilot or demonstration plant testing completed under continuous operation.

Why it applies: Column leach testwork was conducted, which is a strong test scale for metallurgical studies.

Evidence · text

“Column leach testwork was conducted on three composite samples from three locations across the Van Uden Gold laterite deposits.”

Inferred Resourcenegative

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

Why it applies: The Scoping Study is based on laterite resources comprising 10.2% Inferred Resources, and 15% of the mining schedule is Inferred material.

Evidence · text

“The Scoping Study is based on laterite resources comprising Indicated (89.8%) and Inferred (10.2%) Resources. From the life of mine schedule, 85% of mineralisation is classified as ‘Indicated’ and 15% is classified as ‘Inferred’.”

Stale Estimatenegative

Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The MRE was reported to the ASX on April 2026, which is more than 2 years old relative to the current document date of September 2026.

Evidence · text

“The MRE for the Van Uden Gold Project is reported in accordance with The JORC Code (2012 Edition) and was reported to the ASX on April 2026.”

POX/BIOX Routeneutral

Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.

Why it applies: the document describes a pox_biox route ("roaster")

Multi-Domain Testedpositive

Variability across ore domains (oxide, transition, fresh) has been addressed.

Why it applies: 3 distinct composites were tested

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
