Oceana Gold Waihi North Project Waihi North Project Geochemical Assessment – Geochemistry of Tailings and Overburden, Treatment and Mitigation Revision 0 – 17-Jun-2022 Prepared for – Oceana Gold (New Zealand) Limited – Co No.: 2274246 39 AECOM Figure 11. Box plot showing concentration range of Hg in ore material Box plot shows from highest node to lowest node: maximum / 75%ile / Median / 25%ile / minimum concentrations. Box and whisker source data assumes values reported at the laboratory analytical detection limit are equal to the analytical detection limit (e.g. a laboratory value of <0.02 mg/kg is represented as 0.02 mg/kg). Figure 12. Box plot showing concentration range of Sb in ore material Box plot shows from highest node to lowest node: maximum / 75%ile / Median / 25%ile / minimum concentrations. Box and whisker source data assumes values reported at the laboratory analytical detection limit are equal to the analytical detection limit (e.g. a laboratory value of <0.02 mg/kg is represented as 0.02 mg/kg).
