Petra Diamonds Ltd - Trading Update

      20 April 2022 LSE: PDL

Petra Diamonds Limited

Trading Update for the three and nine months ended 31 March 2022

Petra Diamonds Limited ("Petra", the "Company" or the “Group”) announces its unaudited Trading Update for the three months ended 31 March 2022 (the “Quarter”, “Q3 FY 2022” or “Q3”) and the nine months to 31 March 2022 (“9M FY 2022”, “Year to Date” or “YTD”).

Richard Duffy, Chief Executive of Petra Diamonds, commented:

“Petra has benefitted from strong diamond prices during the Quarter underpinned by strong operational, cost and safety performance. The 43% increase in the YTD revenue to US$405.4 million was driven by Exceptional Stones sales contributing US$83.3 million YTD, coupled with the upward trend in diamond prices. This culminated in the significant like-for-like 37.6% price increase we saw in the 4th Tender in March compared to the preceding December 2021 tender. Petra’s production of Exceptional Stones in the Year to Date in part reflects our investment in throughput as part of Project 2022. This Project is now integrated throughout our business and is expected to deliver net free cash of over US$200 million for the three years to June 2022, a significant improvement over our target of US$100-150 million. We also confirm our production, cost and capex guidance as announced at the Investor Day held in February 2022.

“Petra’s balance sheet strengthened further during the Quarter with net debt of US$107.0 million and unrestricted cash balances totalling US$233.2 million at Period end after settling the Group’s first lien facilities of US$88.9 million (including interest) during the Quarter.

“Although we anticipate some pull back in diamond prices from the elevated March tender levels as a result of the economic impact of the war in Ukraine, the structural shift in the diamond market continues to provide positive momentum. This, coupled with our operational improvements driving margin and cash generation, supports a positive outlook for the business with the potential for further reductions in our debt levels.”


Strong performance with quarterly revenue growth of 33%

    --  Strong YTD safety performance
        o Lost Time Injury Frequency Rate (“LTIFR”) down 62% to 0.18 (9M FY
          2021: 0.47)
        o Total injuries, including LTIs, down 20% to 24 (9M FY 2021: 30)
    --  Q3 revenue up 33% to US$140.6 million (Q3 FY 2021: US$106.0 million)
        driven by:
        o Strong prices achieved in the 4th Tender in March 2022 with
          like-for-like prices up 37.6% compared to the preceding December 2021
        o The sale of one Exceptional Stone in the Quarter, a 157.88ct Type IIa
          white stone from Cullinan for US$5.5 million
    --  Notwithstanding the revenue increase, carats sold were down 31% and 16%
        in the Quarter and YTD respectively, given that there was only one sales
        tender in Q3. However, no impact is foreseen on expected sales volumes
        for the full year with further tenders in April and June 2022
    --  Quarterly production up 18% to 830,456 carats (Q3 2021: 704,498 carats)
        with YTD production up 7% to 2,607,880 carats (9M FY 2021: 2,445,360
        carats), largely attributable to Williamson’s resumption of production
        following a period of care and maintenance. In addition, the remedial
        steps taken at Finsch following waste ingress in Q2 FY 2021 positively
        affected the quarterly comparison
    --  Balance Sheet as at 31 March 2022:
        o Consolidated net debt of US$107.0 million (31 December 2021: US$152.3
        o Gross cash of US$249.2 million (31 December 2021: US$272.3 million)
          and unrestricted cash of US$233.2 million (31 December 2021: US$256.7
          million) following settlement of the ZAR404.6 million (US$27.7
          million) revolving credit facility (“RCF”) and ZAR893.2 million
          (US$61.2 million) term loan under the first lien facilities during the
          Quarter. The agreements for the new ZAR1 billion (c. US$68 million)
          RCF with Absa Bank, as announced in February, are in the process of
          being finalised with the new facility expected to become effective
          during April 2022
        o Diamond debtors of US$nil (31 December 2021: US$0.4 million)
        o Diamond inventory valued at US$98.1 million (31 December 2021: US$79.6

Q3 Diamond Production up 18% with the resumption of production at Williamson

This reflects “Petra’s stronger financial and business outlook”. On 26 February, S&P Global Ratings upgraded its outlook for Petra’s bonds to positive “reflecting the recovery in the diamond market and improved liquidity” while maintaining its B rating.

    --  Petra reiterates the detailed operational guidance provided for the FY
        2022 to 2025 period and the guidance for expansion capital expenditure,
        of US$61 million, beyond the FY 2025 guidance period.
    --  Petra does not provide guidance on diamond pricing. However, it should
        be noted that Exceptional Stones have contributed an average of US$47
        million per annum over the last three years, and US$37 million per annum
        over the last five years, to Group revenue.


Our confidence in the outlook for Petra is supported by the structural changes in diamond market supply and demand which continue to underpin prices, despite some expected softening from the highs seen in the March tender as a result of the economic uncertainty arising from the war in Ukraine.  The supportive structural market dynamic, coupled with the operational improvements we have made to drive margin and cash generation, give the potential for both improved financial performance and further reduction in our debt.

Strong YTD revenue growth in a robust diamond market

The 43% increase in revenue for the nine months to 31 March 2022 to US$405.4 million (9M FY 2021: US$284.2 million) was driven in part by the sale of Exceptional Stones totalling US$83.4 million (9M FY 2021: US$52.5 million) comprising the following:

    --  39.34 carat blue diamond from the Cullinan mine which sold for US$40.2
    --  342.92 carat Type IIa white diamond from the Cullinan mine which sold
        for US$10 million (the Company has retained a 50% interest in the profit
        uplift of the polished proceeds, after costs, of the 342.92 carat white
        diamond, as well as an 18.30 carat Type IIb blue diamond which sold for
        US$3.5 million)
    --  32.32 carat pink diamond from the Williamson mine which sold for US$13.8
    --  295.79 carat white diamond from the Cullinan mine which sold for US$13.9
    --  157.88 carat white diamond from Cullinan mine which sold for US$5.5

Revenue also benefited from a 37.6% like-for-like rise in realised diamond prices in the 4th tender as compared to the preceding tender which closed in December 2021.

YTD carats sold reduced by some 16% compared to the comparative period when significantly higher volumes were sold, mostly off-tender, following the inventory build-up witnessed late in FY 2020 after the initial COVID-19 outbreak, while sales in Q3 FY 2022 were limited to one tender during the Quarter. Two further sales tenders are planned in this last quarter, in April and June, as previously announced. The higher diamond inventory at the end of Q3 is expected to unwind to normal year-end levels during the fourth quarter.

Production benefiting from operational improvements and good safety performance

Health and safety

The Lost Time Injury Frequency Rate (“LTIFR”) for 9M FY 2022 decreased to 0.18 (9M FY 2021: 0.47). The LTIs during the Period continued to be of low severity and mostly behavioural in nature. The various remedial actions and behaviour-based intervention programmes previously announced have assisted in achieving the strong improvement in the safety trend. The total number of injuries during 9M FY 2022, which includes LTIs, decreased to 24 (9M FY 2021: 30). Petra continues to target a zero-harm working environment.

COVID-19 remains a risk to the health and safety of the Group’s workforce. Petra has implemented systems and strategies across all of its operations aimed at preventing and/or containing the spread of the virus with an ongoing drive to vaccinate its employees. In South Africa, 2,479 employees have been fully vaccinated (58.4% of the workforce) and 244 partially vaccinated (6% of the workforce), while at Williamson the roll-out has been slower with 173 employees fully vaccinated (14% of the workforce).


9M FY 2022 production was in line with guidance, totalling 2,607,880 carats (9M FY 2021: 2,445,360 carats). Williamson resumed production during the period, having been on care and maintenance since April 2020. The previously reported waste ingress at Finsch has been largely mitigated through the implementation of enhanced drill and blast and draw controls. The convergence of tunnel 41 at Cullinan has been remediated and will continue to be monitored in terms of re-accessing the tunnel.

The Business Re-engineering Projects at Finsch and Koffiefontein concluded in transition plans with recommended deliverables and due dates.

    --  The cost savings and production improvement initiatives at Finsch, to
        enhance margins and ensure a long-term sustainable operation, are being
        implemented as part of the annual three year planning cycle.
    --  While the conclusion for Koffiefontein reaffirmed running the mine to
        closure by 2025 as well as exploring other alternatives in parallel, we
        have been considering options to curtail the negative cash flow. To this
        end, we have been engaging with the Future Forum, comprising organised
        labour and management, with the intention of aligning the operations to
        a reduced tonnage profile and improved efficiencies. Regretfully, this
        is expected to result in job losses.

Production ramp-up at Williamson commenced during the first half and 2.4 Mt ROM was processed in 9M FY2022, yielding 147,876 carats, including the exceptional 32.32 carat pink stone sold during H1 FY 2022.

The diamond market

The strength of the diamond market was evident in the sales results from Petra’s 4th Tender in March.  Strong demand for rough diamonds, with resultant price increases, was seen across all size and quality categories. Like-for-like rough diamond prices increased by 37.6% on Tender 3, which closed in December 2021

The much stronger diamond market has been evident since mid-2021 with Q3 pricing for rough driven by strong sales of polished and increased demand from the manufacturing centres, bolstered by record sales during the festive season. We believe this market dynamic reflects the structural change in underlying supply and demand, which we expect to continue to be supportive. However, the effects of the current conflict in Ukraine have led to some uncertainty as to the impact on the global economy, which we expect will result in some softening in prices from the highs seen in Q3 FY 2022.

Petra is closely monitoring the impact of the war in Ukraine and sanctions on Russian companies.  We also continue to monitor COVID-19 and the impact it may have on clients’ ability to attend tenders and we will remain flexible in our approach to planning upcoming sales events. The final sales for FY 2022 are planned for April and June, bringing the number of tenders to six for FY 2022. 

Strong cash generation supported by Project 2022

Project 2022, a three-year project that commenced in July 2019, is now in its final three months. It has successfully increased cash generation through increased production levels and reduced operating and capital expenditure. The benefits are particularly reflected in the improving operating performance at Cullinan and Finsch. Having achieved net free cash flow of US$182 million for the thirty months to 31 December 2021, we are confident that the Project will deliver over US$200 million in net free cash flow for the three years to end June 2022, comfortably exceeding its US$100 to US$150 million target.  

Continuous business improvement processes are now embedded in the Company’s Operating Model and Organisational Design and is expected to continue to drive future performance improvement.

Williamson Mine – Human Rights update

As previously announced, Petra has implemented remedial initiatives and is putting in place the Independent Grievance Mechanism (“IGM”) as well as community programmes to address the historical allegations of human rights abuses at the Williamson mine in Tanzania. The Government of Tanzania gave its approval to proceed with local stakeholder engagement on the IGM in February 2022 and the first phase commenced during March. Further engagement will take place before the IGM is launched. Following delays in the necessary stakeholder engagements, the current target is for the IGM to become operational during Q4 of this calendar year.

A number of other projects are being put in place to provide sustainable benefits to the communities located close to the mine funded by the one million pounds escrow account established by Petra. The Gender Based Violence project completed all planned activities in the first quarter of this calendar year and the next step is to confirm community action plans with the district commissioner.  The medical services project continues to provide physiotherapy services and further services are being considered. Feasibility studies for the income generating projects (agri business and artisanal mining) are also progressing.
