XHNZI-FM

The concession for XHNZI was awarded on October 28, 1994, to Javier Moreno Valle, a Mexico City businessman who would found XHTVM-TV in Mexico City and a Ciudad Juárez radio station.

En septiembre del año 1999 inicia operaciones al aire con el nombre de La Reina del Cobre 99.1 FM, sus primeros locutores fueron Carlos Sanabia "El Sunguirirungi", Victor Peraza "El amigo de la raza", Manuel Rodriguez "El chuky boys" y Rosy Enriquez.

The station's concession passed to Claudia Elena Lizárraga Verdugo in 2008. Grupo Radio Guaymas transferred operation of the station to Grupo Larsa Comunicaciones, a dominant radio broadcaster in Sonora, in 2017; Larsa immediately dropped the La Reyna del Cobre name and format for its own Toño adult hits format.

In 2023, the station ceased to be operated by Larsa. Grupo Radio Guaymas resumed operating XHNZI as La Reina de la Sierra ("Queen of the Mountains").
