## Minestarters Atlas summary

K2 Gold reported strong initial gold solubility results from its Mojave Project in California, with 211 samples from 2026 drilling at the Dragonfly Zone showing a 97.1% aggregate soluble-gold-to-fire-assay-gold ratio. These new results are consistent with 2020 data, which returned a 95.0% ratio, and confirm the presence of readily leachable gold in an oxide environment. The company plans to conduct more comprehensive bottle-roll metallurgical testing to further evaluate gold extraction and processing parameters.

Reasoning: K2 Gold's initial gold solubility results are very high and consistent across multiple campaigns and labs, strongly indicating that the gold at the Mojave Project is readily leachable in an oxide environment. This significantly de-risks the project's metallurgical profile, although these are preliminary tests and further comprehensive work is planned.

- Positive factor: High gold solubility \(97.1% and 95.0%\) indicates readily leachable gold

- Positive factor: Consistency of results across different campaigns \(2026 and 2020\) and laboratories \(ALS and Bureau Veritas\)

- Positive factor: Visual observation of widespread deep oxidation and low sulphur geochemistry supports amenability to cyanide leaching

- Positive factor: Planning for more comprehensive bottle-roll metallurgical testing is a positive next step to de-risk processing

- Negative factor: Current results are from preliminary cyanide solubility tests, not full-scale recovery tests \(e.g., bottle roll or column leach\)

- Negative factor: Sample selection for solubility tests was biased to samples above a 0.100 g/t Au threshold, so not fully representative of all drilled material

- Negative factor: Solubility tests alone do not establish commercial-scale recovery

Facts used in scoring: 21

## 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.
