In This Article:

VANCOUVER, BC / ACCESS Newswire / April 7, 2025 / (TSX.V:OGN)(OTCQX:OGNRF) Orogen Royalties Inc. ("Orogen" or the "Company") is pleased to announce an update to the mineral reserve and resource estimates on the Ermitaño gold mine in Sonora, Mexico, provided by mine operator First Majestic Silver Corp. ("First Majestic")1 Orogen holds a cash-flowing 2% net smelter return ("NSR") royalty on the 167 square-kilometre Ermitaño concession.

Highlights of 2024 Resource and Reserve update

  • Initial Inferred resources for the Navidad vein system of 2.3 million tonnes consisting of 5.9 million ounces of silver and 249,000 ounces of gold at grades of 81 grams per tonne (g/t) and 3.42 g/t respectively.

  • Only a portion of the delineated vein system at Navidad has been estimated, with significant growth potential.

  • Several areas of mineralization within the Ermitaño mine complex remain open including the Luna vein to the east and the Navidad and Winter veins in multiple directions.

Paddy Nicol, Orogen's CEO, commented, "The initial Inferred resource at Navidad represents an exciting development for Orogen's producing royalty on the Ermitaño Mine, with the announced update increasing contained gold in the Inferred category by 260% year on year. The Navidad resource represents only a portion of the newly delineated vein system with 55,000 metres of drilling planned in 2025 to further test the upside potential of the area."

About the Ermitaño and Navidad Veins

The 167 square-kilometre Ermitaño mining concession is located in Sonora, Mexico approximately 150 kilometres northeast of Hermosillo. Ermitaño is contiguous with the Santa Elena mining claims both owned and operated by First Majestic. (Figure 1).

The Ermitaño vein was discovered in 2016 and developed into a producing underground mine at the end of 2021. Exploration drilling by First Majestic in 2021 identified the Luna vein to the east of the Ermitaño mine and, in 2023, the Navidad vein system to the west (Figure 1), both of which have been included in the 2024 resources. Current reserves and resources are as follow:

From December 31, 2023 to December 31, 2024, the Measured and Indicated resource estimate decreased by 41,000 ounces of contained gold and 6.4 million ounces of contained silver primarily due to mineral depletion, partially offset by infill drilling, changing metal prices, and metallurgical recoveries. The Inferred resource estimate increased by 2.57 million tonnes of ore, 257,000 ounces of contained gold and 6.11 million ounces of contained silver primarily related to discovery and first-time reporting of the Navidad resource.
