Palta Dorada

A high-grade 100% owned Au-Ag-Cu Property

The Palta Dorada property is in the Ancash mining department in northern Peru and covers an area of approximately 2,250 hectares. The Property is accessible from the Aguila Norte plant by approximately 140 km of mainly paved roadway and from the Pan American highway at about 600m above sea level.

The development work by Peruvian Metals at Palta Dorada concentrated on the main San Juan vein whose surface exposure shows at least an 840-metre strike length. Work to date includes a 160-meter access drift on the lower 895-metre level. The Company has also opened and widened a 53-metre shaft where artisanal miners had extracted hundreds of tonnes of highly mineralized ore that was sold to local toll mills. Seven chip samples were taken at various depths in the shaft from a quartz vein containing sulphides. Previously reported assay results from these samples range from: 3.06 g/t Au to 24.1 g/t Au, 36 g/t Ag to 865 g/t Ag, 0.31 % Cu to 4.94 % Cu over an average width of 0.60 metres.

The weighted average of the assay results is 10.51 g/t Au, 329 g/t Ag and 1.74 % Cu.

The shaft clearly shows the transition from the oxide zone to the sulphide zone. Assay results from the oxide zone within the shaft range from 0.87 to 55.3 g/t Au. In 2022, 31 tonnes of oxide gold mineral were extracted in the shaft area, shipped, and sold to a local mill in Southern Peru. The mineral averaged 8.83 g/t Au with a 90% recovery.

Artisanal Workings over 800 meter strike length

On the initial site visit, approximately 65 tonnes of mineral had been selectively extracted; hand sorted and sacked outside of the main working ready for shipment to tolls mills in Southern Peru. Two composite samples were taken from various sacks and returned an average grade of 26.7 g/t Au, 23.76 oz/t Ag and 3.16% Cu. A third random composite sample was taken from these sacks and used for metallurgical work. The work performed on this sample by Procesmin Ingenieros Laboratories had a head grade of 23.21 grams/MT Au, 29.04 oz/MT Ag and 4.95% Cu. Metallurgical work showed that two concentrates can be produced. The first and more valuable concentrate graded 125.59 grams Au/MT, 4,808 grams Ag/MT and 24.41% Cu. A second Au-pyrite concentrate was also produced graded 11.46 grams/MT Au, 565 grams Ag/MT and 2.90% Cu.

Mineral Sacks ready for shipment to toll mills located in Southern Peru

A second well-mineralized structure north of the main structure has had twelve samples taken from oxide material over a strike length of approximately 480 meters. All samples were strongly oxidized, and assay results ranged from 1.40 g/t Au to 17.3 g/t Au, 10.8 g/t Ag to 456 g/t Ag over widths of 0.20 to 0.80 meters. The weighted average of the results is 7.92 g/t Au and 102 g/t Ag. A mini-bulk sample was taken for metallurgical work from sacks containing oxide gold material. A bottle-roll metallurgical test was performed with a head grade of 13.0 g/t Au and 102 g/t Ag returned 92.15-per-cent gold and 65 percent silver recoveries over 36 hours.

On January 15, 2024, Peruvian Metals announced that the company To acquire the remaining 50% interest in Palta Dorada, Peruvian Metals will pay Rio Silver $250,000 US over five months. An initial payment of $25,000 US has been made with Rio Silver retaining a 3% NSR which is capped at $2 million US. Peruvian Metals must also ensure that the royalty will pay a minimum of $50,000 US per year for five years.
