About Rio Silver Inc.

Rio Silver Inc. is a resource company that has been selectively identifying and acquiring precious metal assets that afford the best possible leverage and returns in anticipation of an increasingly more favorable precious metals bull market. At the Company’s recently acquired Palta Dorada Property in central Peru, a high-grade mesothermal gold and silver vein system is currently being bulk-sampled and processed by earn-in partner, Peruvian Metals Corp.(“Peruvian”). The Company’s partner has earned a 50% interest by installing and then expanding (due to Covid protocol) a 20-man camp and support complex and then developing 150 meters of access tunnel to intercept the targeted sulfide mineralization. Recently access improvements to the upper workings have been initiated improving an access shaft for the installation of a mechanised skip which will expedite access for a bulk sampling campaign within the previously sampled sulfide mineralization. Peruvian operates the nearby Aguila Norte commercial mill where the extracted mineral from the bulk sampling campaign will be processed. Bulk sampling may be ramped up if successful and could become a cashflow to assist the Company’s overall exploration plans in a non-dilutive, shareholder friendly way. We remain ever impressed and optimistic by the resilience and ingenuity of our host country as Peru continues to endorse supportive mining policies ensuring continued growth and opportunity throughout Peru.
