RIO SILVER INC. REPORTS: INITIAL SILVER – GOLD – LEAD RECOVERIES OF 85 %, 74 % AND 77% RESPECTIVELY FROM THE MARIA NORTE IN CENTRAL PERU 

Rio Silver Inc. has announced positive initial metallurgical test results from its Maria Norte project located in Central Peru's historic silver district. The company achieved notable recovery rates through conventional flotation methods, with silver recovering at 85%, gold at 74%, and lead at 77%. These results are particularly encouraging as they demonstrate the project's potential for commercial viability using established processing techniques.

The test work highlights several key advantages for the Maria Norte project, including the achievement of high-grade concentrates and importantly, low arsenic content. Low arsenic levels are crucial for metallurgical processing as they reduce potential penalties and processing complications that can significantly impact project economics. The use of conventional flotation methods also suggests that the project could benefit from lower capital and operating costs compared to more complex processing requirements.

For Rio Silver, these initial results represent an important milestone in advancing the Maria Norte project toward potential development. The combination of good recovery rates across multiple valuable metals - silver, gold, and lead - positions the project favorably in Peru's established mining jurisdiction. The historic nature of the district provides additional confidence in the geological setting and infrastructure accessibility.

The successful initial metallurgical work sets the foundation for more comprehensive testing and potentially enhanced recovery optimization. As Rio Silver continues its metallurgical program, these baseline results provide a solid platform for further technical advancement and eventual economic assessment of the Maria Norte project's commercial potential.
