A detailed description of the SPEI drought index is presented on page 9 . The SPEI index is relative to average or normal conditions for the site, and the SPEI scale: 0.99 to -0.99 Normal, -1.00 to -1.49 Moderately dry, -1.50 to -1.99 Severely dry, <-2.00 Extremely dry. 5 Based on data from the World Bank Group’s Climate Knowledge Portal. 6 Climate statistics based on the Cortez mine site. 7 Climate statistics based on the South Laverton property. Interannual  variability  can  be  a  significant  water  risk.  This  risk  is  highlighted  in  the  table  where  the  wettest  month  in  the  precipitation  record  is  divided  by  the  average  annual  precipitation.  Three  jurisdictions  stand  out  as  having  unusually  high  ratios:  Coquimbo,  Chile;  Zacatecas,  Mexico;  and  Mato  Grosso,  Brazil,  indicating  the  potential  to  have  precipitation  that  could  potentially  cause  flooding.
