Rio Silver Achieves High Recovery Rates in Peru Metallurgical Tests
Event summary
- Rio Silver reports initial metallurgical recoveries of 85% for silver, 74% for gold, and 77% for lead from the Maria Norte property in Peru.
- Two concentrates produced: a high-grade silver-gold-lead concentrate and a lower-grade gold-silver-pyrite concentrate, both with low arsenic levels.
- The Maria Norte property is adjacent to Silver X’s Tangana mining unit, with permitting in progress for bulk sampling and processing.
- Metallurgical work ongoing to optimize processing for two distinct vein types identified at the site.
The big picture
Rio Silver’s high recovery rates from metallurgical testing position it favorably in Peru’s competitive silver mining sector. The company’s focus on low-arsenic concentrates could enhance its marketability, while the adjacent production at Silver X’s Tangana unit underscores the region’s mining potential. The strategic advancement of Maria Norte aligns with Peru’s status as the world’s second-largest silver producer, highlighting the company’s push toward near-term development.
