Ore Grade Control Antamina

  • RC Grade Control – Geodrill

    RC Grade Control Drilling (in-pit grade control) is used in open cut mines to define ore grades and also provide knowledge for mine planning and blasting. RC/GC is typical drilled to optimal depths of 48 meters using hole Ø 125-140mm. This information is critical to reduce waste rock (dilution) in concentrator feed as dilution can vary greatly. RC grade control is the most cost effective and
