A sensitivity analysis determines how different values of an input variable impact a particular output variable under a given set of assumptions. The sensitivity analysis isolates the input variables and then records the range of possible output variable outcomes. DSA stands for the innovative Deterministic Sensitivity Analysis solution in Cirrus. Differently of other desktop mining […]
The economic model is built over the geological block model and it is translated as the associated monetary value of a given ore block. In general, the economic model in Cirrus uses the same input settings applied to either open pit or underground stopes optimization in desktop mining solutions.
The CIM Definition Standards establishes that Mineral Reserve is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying […]
The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards establishes that the Mineral Resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or […]
In mining, the geological block model is the foundation of any mining project as it contains all the grade and material information for the mining deposit. The success and failure of a mining operation can rest largely on how the block model is used to evaluate mineral assets. The picture above shows the concept of […]
