## Minestarters Atlas summary

RPX Gold announced positive preliminary metallurgical test results from its Wawa Gold Project in Ontario, showing average gold extractions of 93.4% for open-pit material and 88.3% for underground material via cyanidation bottle roll tests. These results, conducted by SGS Canada Inc., exceed the 88.0% recovery assumed in the 2026 PEA for open-pit material and validate the use of conventional cyanidation, supporting the project's advancement towards a prefeasibility study.

Reasoning: The preliminary metallurgical test results for the Wawa Gold Project show strong gold recoveries, particularly for open-pit material, exceeding previous PEA assumptions and validating conventional cyanidation. While the testwork is bench-scale and some samples contain arsenic, the overall results are positive for de-risking the project towards a PFS.

- Positive factor: High gold recovery

- Positive factor: Recovery improved vs PEA assumptions

- Positive factor: Conventional processing route validated

- Positive factor: Multi-domain testing

- Positive factor: QP/CP sign-off

- Positive factor: Accredited laboratory

- Negative factor: Preliminary results \(not all samples tested\)

- Negative factor: Bench-scale testwork \(bottle roll\)

- Negative factor: Presence of arsenopyrite/arsenic in some samples

Facts used in scoring: 26

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: The average gold extraction for open-pit samples was 93.4%, which is strong to exceptional for a mill route.

Evidence · text

> gold extraction averaging 93.4%

**Recovery Improving**

Polarity: positive

Definition: Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: The average gold recovery for open-pit samples of 93.4% is higher than the 88.0% gold recovery assumed in the 2026 PEA.

Evidence · text

> 93.4%, compared to 88.0% gold recovery assumed in the 2026 PEA.

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The test work involved cyanidation bottle roll testing, which is a conventional mill processing route.

Evidence · text

> conventional cyanidation recovery

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The metallurgical test work consisted of cyanidation bottle roll testing, which is a bench-scale method.

Evidence · text

> cyanidation bottle roll testing

**Multi-Domain Tested**

Polarity: positive

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

Why it applies: Samples were taken from zones defined as potential initial open pits and underground material, covering different areas of the mine plan.

Evidence · text

> samples within zones defined as potential initial open pits. For underground material

**Refractory Ore**

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: 10 of the 26 samples contained arsenopyrite with arsenic content ranging from 300 ppm to 2,850 ppm, indicating potential refractory characteristics.

Evidence · text

> 10 of the 26 samples containing arsenopyrite with arsenic \(“ As ”\) content from 300 parts per million \( “ppm” \) to 2,850 ppm As.

**QP/CP Signed**

Polarity: positive

Story-specific tag

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: Jean-François Montreuil, P.Geo., a Qualified Person, reviewed and approved the scientific and technical information in the press release.

Evidence · text

> Jean-François Montreuil, P.Geo., Vice President, Exploration at RPX Gold, and a Qualified Person as defined under National Instrument 43-101, has reviewed and approved the scientific and technical information in this press release.

## 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.
