Proyecto de Stibnite Gold

Project Highlights:

  • Diseño de Depósito de Relaves
  • Ingeniería Geotécnica
  • Ingeniería Civil
  • Hidrología Completa del Sitio
  • Balance de Aguas Completa del Sitio
  • Diseño de Desvíos
  • Estudio de Prefactibilidad

El Proyecto de Stibnite Gold está ubicado en la zona remota de las Montañas Rocosas de Idaho central, cerca del Pueblo de Yellow Pine.  Es un proyecto de oro-antimonio de Brownfields que cuenta con tres canteras a cielo abierto y una producción esperada de la planta de 22.000 tpd. Este Proyecto presenta desafíos en relación con el terreno y restricciones ambientales. Tierra Group llevó a cabo el diseño preliminar de factibilidad del depósito de relaves propuesto, así como también de los desvíos de aguas y del manejo de aguas en todo el sitio, incluyendo contenido relevante para informe técnico de prefactibilidad en cumplimiento con NI-43-101. Tierra Group desarrolló el diseño de prefactibilidad para el depósito de relaves, los desvíos de aguas superficiales, y el plan de cierre para el depósito de relaves y el botadero de roca de desecho. El depósito de relaves se cubrirá con un sistema de revestimiento de geosintético compuesto e incluye un terraplén de enrocado de aproximadamente 460 pies de alto que se construirá en múltiples etapas durante el desarrollo del proyecto. Los desvíos constan de un canal que transporta a un arroyo perenne de montaña alrededor del depósito de relaves, y un canal/túnel combinado que conduce a un río alrededor de una de las canteras a cielo abierto. El desvío del túnel se diseñó para facilitar el paso de la migración de salmones, dando acceso a un hábitat de desove que había estado bloqueado durante décadas debido a actividades mineras previas en la zona.
