## Minestarters Atlas summary

TDG Gold Corp. reported new drill results from its Aurora West Zone, including a significant step-out hole \(TDG25-020\) that extended mineralization by 350 metres down-dip with high-grade gold and copper intercepts. The company also identified a new porphyry-style alteration zone 600 metres north of the Aurora Complex, highlighting the district's exploration potential. Additionally, the release included details of the 2024 Shasta Mineral Resource Estimate, which outlines substantial indicated and inferred gold-silver resources.

Reasoning: TDG Gold Corp. announced strong drill results that significantly expand the Aurora West Zone mineralization and identified a new porphyry target, demonstrating substantial exploration potential. The accompanying Shasta MRE, while a restatement, provides a robust gold-silver resource that complements the exploration success.

- Positive factor: Step-out drilling significantly extended mineralization at Aurora West Zone.

- Positive factor: High-grade gold and copper intercepts were reported.

- Positive factor: A new porphyry target was identified, indicating district-scale potential.

- Positive factor: The resource estimate is NI 43-101 compliant and signed off by a Qualified Person.

- Negative factor: True width is unknown for the reported drill intercepts.

- Negative factor: The resource estimate is a restatement from 2025, limiting novelty for the MRE itself.

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

Facts used in scoring: 49

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drill hole TDG25-020 represents the largest step-out completed to date at the Aurora West Zone and extended mineralization approximately 350 m down-dip.

Evidence · text

> Phase II \(northern step-out\) drill hole TDG25-020 \(Table 2\) represents the largest step-out completed to date at the Aurora West Zone and marks a meaningful expansion of Aurora West Zone mineralization. The hole intersected mineralized intervals grading 1.02 grams per tonne \(“g/t”\) gold \(“Au”\) and 0.43% copper \(“Cu”\) over 14.0 m, and 0.57 g/t Au and 0.29% Cu over 24.0 m hosting in a broader interval of 86.3 m of 0.49 g/t Au and 0.23% Cu. TDG25-020 was terminated within mineralized compositionally andesitic rocks. These results extend mineralization approximately 350 m down-dip from drill hole TDG25-012

**QA/QC Disclosed**

Polarity: positive

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

Why it applies: The release details chain of custody, use of certified reference materials, blanks, and duplicates, and mentions analysis by Bureau Veritas and ALS Global laboratories.

Evidence · text

> Samples for the GSN 2025 drill program followed chain of custody between collection, processing and delivery to a Bureau Veritas \(“BV”\) or ALS Global \(“ALS”\) laboratory in Vancouver, B.C and North Vancouver, respectively. The drill cores were delivered to the core shack at TDG’s Baker Mine site, and processed by geologists who inserted certified reference materials, blanks, and duplicates \(pulp and coarse\) into the sampling sequence at regular intervals.

**QP/CP Signed**

Polarity: positive

Definition: 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: The technical content of the news release has been reviewed and approved by Steven Kramar, MSc., P.Geo., VP Exploration for TDG, a qualified person as defined by National Instrument 43-101.

Evidence · text

> The technical content of this news release has been reviewed and approved by Steven Kramar, MSc., P.Geo., VP Exploration for TDG, a qualified person as defined by National Instrument 43-101.

**Apparent Width Only**

Polarity: negative

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

Why it applies: The drill results tables explicitly state that 'True width is unknown'.

Evidence · text

> True width is unknown.

**Compositing Transparent**

Polarity: positive

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

Why it applies: Composite results were built using 0.30 g/t Au and/or 0.1% Cu cut-off, and the possibility of internal dilution is mentioned.

Evidence · text

> Composite results were built using 0.30 g/t Au and/or 0.1% Cu cut-off, although there may be intervals within the composite below 0.30 g/t Au and/or 0.1% Cu.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The Mineral Resource estimate was estimated in accordance with the CIM 2019 Best Practices Guidelines, as required by NI43-101.

Evidence · text

> Mineral R esources are reported using the 2014 CIM Definition Standards and were estimated in accordance with the CIM 2019 Best Practices Guidelines, as required by NI43-101.

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document presents an updated Mineral Resource Estimate for Shasta, effective December 29, 2024.

Evidence · text

> TDG completed ~13,250 m of modern large diameter diamond drilling at Shasta in 2021-2022 and published an updated Mineral Resource Estimate 4 on January 08, 2025 .

**PEA-Supporting**

Polarity: neutral

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

Why it applies: The resource estimate includes detailed assumptions for economic extraction, including metal prices, recoveries, and costs, which are typical for supporting economic studies.

Evidence · text

> Th e Mineral Resource has been confined by a “reasonable prospects of eventual economic extraction” pit using the following assumptions, which were estimated from comparable projects: Au price of US$2,250/oz, Ag price of US$25/oz at an exchange rate of 0.74 US$ per CDN$; a 1.5 % NSR royalty; 93 % metallurgical recovery for Au, based on past TDG test work, historical mill records 4 and nearby project comparables; 86 % recovery for Ag based on nearby project comparables 6 and, while prior MREs assumed somewhat lower Ag recoveries based on historical mill records 4 and limited past TDG test work, test work was not optimized for Ag recoveries. Further, test work at comparable projects indicate that improvement could be expected ; 99.9 % payable Au; 95.0 % payable Ag; US$7.00/oz Au and US$3.00/oz Ag offsite costs \(refining, transport and insurance\); Mining costs of CDN$4.00/tonne mineralized material; Processing Costs of CDN$15/tonne and G&A of CDN$8.00/tonne processed; Pit slopes of 45 degrees.

## 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.
