Modified after Baker et al., 2022 Porphyry copper-gold mineralisation at
East Ridge, a new discovery at the Red Chris deposit, northwestern British
Columbia. Roundup Coreshack poster. Newcrest Mining Limited.
The Red Chris drill results have been extracted from Newcrest's releases
titled ""Quarterly Exploration Report" dated 29 April 2021, 22 July 2021 and
28 October 2021. The exploration release includes the exploration results
for all material drill-holes (including those referred to on this slide).
