14.6 Exploratory Data Analysis

Exploratory data analysis (EDA) includes basic statistical evaluation of the assays and composites for Cu, CuSS, Mo, Ag, Au, Fe, Mg, Mn, Pb, Zn, As, Ca, Na, P, S, Al, and K. The EDA was conducted separately for each mineralized envelope. The composite statistics for these variables are summarized in Table 14-8 and Table 14-9 of the block model validation section.

It is worth noting that Fe, Mg, Mn, Pb, Zn, As, Ca, Na, P, S, Al and K were also interpolated and validated in each of the deposits. These variables, together with Cu, CuSS, Mo, and Ag, were used as inputs to the machine-learning models. However, to be succinct, only the economic metals are detailed in this Technical Report.
