Aris Mining is trading 10.09% up at $19.36 after copper approached record highs and broader materials-sector strength lifted mining sentiment.
- The materials sector is up 2.06% during regular trading.
- No clearly confirmed company-specific announcement was identified for August 19, 2026; latest listed releases include the August 4 Seasif update and July 29 Q2 results.
- Bitcoin is up 0.29% and Ethereum 0.85% since the previous close, so crypto is not the primary driver.
