Orla Mining Unveils Significant Underground Mineral Resource at Camino Rojo

Orla Mining Ltd. (NYSE:ORLA) is one of the best performing mid cap stocks so far in 2025. On June 5, Orla Mining announced the initial underground Mineral Resource estimate for its Camino Rojo deposit in Zacatecas, Mexico. This estimate extends the mineralization down-plunge from the existing oxide open pit into the Camino Rojo Sulphides and the newly defined Zone 22.

The initial underground Mineral Resource estimate, effective March 31 this year, includes a Measured and Indicated Mineral Resource of 50.1 million tonnes (Mt) at an average grade of 2.45 grams per tonne (g/t) gold (Au), 10.6 g/t silver (Ag), and 0.25% zinc (Zn), equating to 2.58 g/t gold equivalent (AuEq). Contained metal totals 3.95 million ounces (Moz) gold, 17.05 Moz silver, and 278 million pounds (Mlbs) zinc, for a total of 4.16 Moz AuEq.

Orla is currently undertaking a 15,000-meter drilling program in 2025, with 11,000 meters drilled to date, aiming to upgrade and expand the upper part of the Zone 22 resource. This program is expected to conclude in Q3 2025. In November last year, Orla submitted permit applications to Mexico’s environmental agency, SEMARNAT, which include amendments for the existing oxide open pit and new requests for an underground portal and exploration drift.

Orla Mining Ltd. (NYSE:ORLA) acquires, explores, develops, and exploits mineral properties. It primarily explores gold, silver, zinc, lead, and copper deposits.
