Having reset its cost base, delivered new life-of-mine plans with a smooth capital profile, the focus of Petra Diamonds is very much around refinancing its $250-million loan notes.

"We plan to get that done before the end of this calendar year," Petra Diamonds CEO Richard Duffy outlined to Mining Weekly in a Zoom interview. (Also watch attached Creamer Media video.)

The refinancing of the loan notes will place the London-listed, Africa-active diamond mining company in a position to execute on the growth potential of its long-life assets.

These are iconic Cullinan diamond mine in Gauteng, the Finsch mine in the Northern Cape, and Williamson mine in Tanzania.

It will also allow the company to begin to execute on its value-led growth strategy presented by not only its existing asset base, but also through other opportunities.

"We'll be able to deliver and leverage what we believe will be a much more supported market from next calendar year," Duffy commented.

The main focus of Petra's recent investor day was to demonstrate the resilience of the business through steps implemented over the recent months.

The key features were cutting the cost base by $30-million on a sustainable annualised basis.

Through mine replanning, it has also smoothed its capital profile going forward basis to around $100-million a year or less.

The main reason was to ensure that the business is cash generative from this financial year (FY) 2025 and refinance its loan notes, which mature in March 2026, before this calendar year-end.

Mining Weekly: What, specifically, were the life of mine updates and what does this mean for production as well as the future of Petra?

Duffy: In the case of Cullinan mine, we have a board-approved mine plan that goes through to 2033, and the potential through further extensions in the mine itself to be mining beyond 2050. At Finsch mine, we highlighted that the board-approved mine plan sees mining through to 2032 but with the potential to continue mining below the current Block 5 through to 2040. Williamson has an approved mine plan to 2030 with extension opportunities and growth opportunities well into the 2040s. We also provided guidance for the next five years so that we could create some visibility in terms of our production, which we see growing from the current levels of around 2.8-million carats annually to around 3.5-million carats a year by 2028. Most of that growth comes from increasing grade, both at Cullinan and at Finsch.

You speak of a lower-for-longer diamond market, how does that impact Petra?

What we're seeing is a diamond market that we expect will continue to remain a little softer through to the end of this calendar year. We took measures towards the end of last year in recognition of what we expected to be a weaker-for-longer market. The steps we took back in October 2023 around deferring some of our capital spend and initiating that cost savings programme meant that we were able to reduce net debt by $11-million from the end of December 2023 to the end of June 2024, the end of our FY 2024. The measures taken ensured that we stopped any cash burn in the business, even in a tougher market. The steps we've taken around costs and smooth capital profile mean that we'll continue to be resilient as a business, and be cash generative from this financial year 2025 onwards. So, we're well placed to benefit from an improving market, which we expect to see from next calendar year.

What makes you are more confident about the market in the medium- to long-term?

What we've seen in the market is the culmination of a number of factors that have created some headwinds for us, and that really has been on the back of the higher interest and inflation rates that have been a little more stubborn than expected, the slower return of demand from China, which is an important market for diamonds, and the disruption caused by the rapid growth of lab gro...
