VANCOUVER, British Columbia, March 26, 2025 (GLOBE NEWSWIRE) -- Rio Silver Inc. (“Rio Silver” or the “Company”) (TSX.V: RYO) (OTC: RYOOF) announces that it has signed a definitive agreement for the acquisition of the Minas Maria Norte (“Maria Norte” or the “Property”) high grade polymetallic silver, exploitation / exploitation property, from Peruvian Metals Corp. (“Peruvian”) (TSX-V PER) being subject to regulatory approval.

The Property is located in Southern Peru in the historic Huachocolpa Mining District, Municipality of Huancavelica. The Property has been held by Peruvian for the past 18 years adjacent to significant silver production with announced world class expansion plans. Previous exploration campaigns by Peruvian shows that the property hosts many polymetallic veins with significant gold credits. Located in the heart of the prolific Huachocolpa Silver District, environmentally friendly hydro power, good infrastructure, labor and logistical support is available.

Two significant mineral processing flotation plants operate nearby: Compañia Minera Kolpa plant at 1440 tonnes per day and SilverX Mining’s (“SilverX”) plant called Recuperada at 720 tonnes per day These plants are located 8 km and 13 Km respectively from Maria Norte. In addition, SilverX’s Tangana Mining Unit which is part of their Nueva Recuperada project is currently in production and is located 2.5 km to the southwest of Maria Norte. It appears that the sub-parallel mineralized structures on Maria Norte are similar to the mineralized structures on the Tangana Mining Unit. SilverX completed a Preliminary Economic Assessment of the area and is published on Sedarplus in April 2023.

The Maria Norte property is 368 hectares in size covering numerous, Au-Ag-Zn-Pb veins that display evidence of historic artisanal exploitation. Five gold-bearing polymetallic structures were mapped by the Company’s geologists and remain open along strike. The lengths of the structures as currently mapped are 40 to 400 meters with variable widths from 0.15 to 4 meters and occur in a vein corridor nearly 600 meters wide

The main structure at Maria Norte, the Castorindo Zone, has provided the highest-grade gold values from within the land package, having five samples ranging in width from 0.18 to 0.70 meters and assaying 13.5 to 40.3 grams per tonne gold along with 162.9 to 1,128 grams per tonne silver. High-grade silver (1,848 grams per tonne) was also encountered at the Jess structure on a sample 0.3 meter in width. Other veins not yet mapped include five samples with widths of 0.2 to 0.7 meters with gold values ranging from 0.89 to 1.55 grams per tonne, silver values ranging from 82.8 to 682 grams per tonne, and up to 4.3 per cent zinc and 9.7 per cent lead.
