## Minestarters Atlas summary

Tudor Gold, American Creek's JV partner, has reported improved metallurgical results for the Goldstorm Deposit, specifically increasing gold recoveries to over 80% through the addition of a cyanide leach step on flotation tails. The testing produced a high-grade copper concentrate \(30.3% Cu, 36.5 g/t Au, 99.8 g/t Ag\) and demonstrated successful gold extraction from both rougher tails and pyrite concentrates.

Reasoning: The update demonstrates a material improvement in gold recovery through process optimization \(leaching tails\), significantly enhancing the economic potential of the Goldstorm deposit.

- Positive factor: Significant increase in gold recovery \(from 63.8% to 80.2%\)

- Positive factor: High-grade copper concentrate produced \(30.3% Cu\)

- Positive factor: Successful optimization via cyanide leach of flotation tails

- Positive factor: QA/QC disclosed with QP sign-off

- Negative factor: Results are from blended samples, limiting direct comparison to previous locked cycle tests
