International diamond producer Petra is relying on stronger performance in the June qtr after a slow start to CY2020 particularly at Cullinan in South Africa and a pit slump at the Williamson mine in Tanzania.
Petra delivered 2.07Mct for the Dec half (H1FY20), up from 2.02Mct a year earlier, and on track to exceed its 3.8Mct FY20 guidance - prior to the slowdown.
