# Golden Minerals reports improved concentrate sale terms, evaluates Velardeña restart without BIOX plant

## Summary
- First shipment of 142 tonnes of gold-rich pyrite concentrate under improved terms to buyer in Manzanillo, Mexico.
- Evaluating restart of Velardeña mines as early as mid-2023 without building BIOX facility, reducing capex.
- Currently processing 3,000 tonnes of previously mined stockpiled material from Santa Juana mine for future shipments.
- Initial production to target veins that showed best test mining results in 2022; ore-sorting not required given improved revenue.
