HIGHLIGHTS

·     Lost Time Injury Frequency Rate ("LTIFR") for the nine months to 31 March 2019 of 0.19 (FY 2018 YTD: 0.18).

Q3 FY 2019 Production and Sales - Summary

1.     'Other' includes alluvial diamond mining at Williamson.

Richard Duffy, Chief Executive Officer, commented:

"I have visited all of Petra's operations and am impressed by the very capable teams and quality asset base, strongly reinforcing my initial views of the business. Our capital investment phase is largely over and we are well positioned to benefit from this as we move towards steady state operational performance.

I am pleased with the incremental improvement in operational performance at Cullinan, Koffiefontein and Williamson and despite a challenging January, Finsch's performance through February and March is as expected. Our focus remains on the delivery of free cash flow to reduce our net debt and generate future options for the Company."

COMMENTARY

Health and safety

·     The Group's LTIFR for the nine months to 31 March 2019 remains well managed at 0.19 (FY 2018 YTD: 0.18). The Company continues to focus on its goal of a zero-harm workplace.

Production

·     Q3 production of 924,228 carats (Q3 FY 2018: 992,315 carats) reflected increased production at Cullinan, Koffiefontein and Williamson, offset by lower production at Finsch. Despite power interruptions across South Africa during the quarter and the Company's compliance with Eskom's request for load curtailment, the operational impact of these interruptions was largely offset by a number of mitigating measures, with negligible impact on production.

·     Production for the nine month period to 31 March 2019 increased 4% to 2,943,374 carats (FY 2018 YTD: 2,836,272 carats) following a 6% increase in ROM carats produced to 2,845,234 carats (FY 2018 YTD: 2,683,959 carats), partially offset by the planned reduction in tailings throughput at Finsch. Production guidance of 3.8 - 4.0 million carats for FY 2019 is maintained.

·     Finsch Q3 production decreased 30% to 387,370 carats (Q3 FY 2018: 553,669 carats) which is ca. 55,000 carats below expectations, 80% of which relates to a delay in the planned winder upgrade and a belt tear on the main underground conveyor, both of which occurred in January 2019. These issues have been addressed, with underground production in both February and March 2019 being in line with expectations. The balance of the Q3 shortfall relates to lower grades in the ROM surface stockpiles (overburden dumps), which are nearing depletion. Underground ROM grades remained in line with guidance during the quarter.

·     Cullinan Q3 production increased 22% to 432,001 carats (Q3 FY 2018: 354,403 carats) following a 10% increase in ROM tonnes treated to 1.04 Mt (Q3 FY 2018: 0.95 Mt) and ROM grades remaining in line with expectations at 40.0 cpht (Q3 FY 2018: 36.2 cpht). The installation of the remaining draw points across the footprint of the C-Cut Phase 1 block cave is progressing as planned, with completion expected during H1 FY 2020, reaching maturity during FY 2020. With the progression across the C-Cut footprint, an improvement in the incidence of larger stones is evident, which included the recovery of two gem-quality stones larger than 100 carats each during the Period, and also demonstrates the ability of the plant to recover these stones. Proactive management of the Eskom load curtailment saw tailings production halted during the quarter to focus on higher value ROM production.

·     Koffiefontein Q3 production increased 42% to 17,355 carats (Q3 FY 2018: 12,180 carats), with ROM throughput achieving its annualised target of 1 Mtpa, following the return to stable production after the community unrest related to municipal service delivery experienced in Q2 FY 2019.

·     Williamson Q3 production increased 21% to 87,503 carats (Q3 FY 2018: 72,063 carats) with production continuing in line with expectations. Three gem-quality pink stones were recovered and sold during the Period, positively impacting the average price achieved.

Sales and Diamond Market

Diamond Market

·     There were signs of stabilisation in the diamond market during Q3 with steady demand across all size categories.

Diamond Sales and Prices

·     Q3 revenue decreased 7% to US$135.2 million (Q3 FY 2018: US$145.7 million), mainly due to lower production from Finsch. Revenue for the nine month period to 31 March 2019 increased marginally to US$342.4 million (Q3 FY 2018: US$337.4 million).

·     Rough diamond prices were up ca. 1% for Q3 on a like-for-like basis in comparison to Petra's results for H1 FY 2019, the six month period to 31 December 2018.

·     A further two tenders will be held during Q4 (April to June 2019).

·     Prices realised during Q3 are summarised in the table below.

Succession Planning

·     The Nomination Committee is in the final year of its three year Succession Plan. During the Period, the Company announced the appointment of Richard Duffy as CEO effective 1 April 2019.

·     In a recent statement regarding the voting at the Company's November 2018 Annual General Meeting the Board confirmed that given the recent CEO appointment and to ensure continuity and stability of leadership and management, the appointment of a new Chairman was not considered appropriate at this time. The Nomination Committee expects to make further changes to the composition of the Board during this calendar year.

Corporate

·     A summary of the Group's current cash, diamond inventories, debtors, borrowings and net debt is set out below.

·     The Company's ZAR1.5 billion (US$103.6 million) South African banking facilities remain undrawn and available, with an unrestricted cash balance of US$84.5 million as at 31 March 2019.

·     Discussions with South African lenders relating to covenant re-profiling are expected to be finalised by 30 April 2019.
