Sibanye-Stillwater’s US operations in the midst of a major growth phase

Sibanye-Stillwater’s Blitz project development area, which is adjacent to its Stillwater mine, in Montana, US, is in the midst of a significant growth phase, says executive VP for the US region Chris Bateman.

He told the media on a conference call last week that the expanded Stillwater mine was expected to ramp up to its targeted production rate of 850 000 oz in the fourth quarter of 2021.

The Stillwater mine currently produces 550 000 oz/y of gold.

Bateman reaffirmed the group’s belief that there is good growth potential in the orebody below the current Blitz area – known as Lower Blitz – as well as further development opportunities at the East Boulder mine and further down – below the current Blitz mine.

The East Boulder, Bateman explained, was characterised by lower grades; however, the orebody was much more consistent, which led to lower mining costs. While Stillwater had some high-grade stopes, both Stillwater and the Blitz project were running at more than 20 g/t.

At year-end, the miner expects Blitz to move up significantly on the y-access, especially considering that the miner has had some good results on the project in terms of drilling and developing stope blocks.

Sibanye last week reported that underground platinum-group metals (PGMs) production at its US operation was 3% higher at 139 178 oz in the third quarter, with early production shortfalls at the Stillwater mine having been recovered at the end of the quarter.

Fourth-quarter production was expected to be higher, owing to the implementation of a second stope block at the Blitz project.

Meanwhile, in late October, Sibanye concluded a transaction with Regulus Resources and the newly formed Argentinian subsidiary of Regulus, Aldebran Resources, which was established to unlock value at its Altar copper/gold project, in the San Juan province of Argentina.

According to Bateman, Regulus was looking to spend an additional $30-million to increase its share in Aldebran to 60%.

This transaction, he said, would provide Sibanye with greater exposure in the country.

Downward Trend

Bateman, meanwhile, enthused that the all-in sustaining costs (AISCs) for Sibanye’s US operation had been on a pleasing downward trend during the third quarter.

Sibanye was, however, still expecting to finish the year within its guidance and was targeting an AISC of about $550/oz by the end of 2021 or the beginning of 2022.

The average realised selling price dipped to $896/oz in the third quarter, but Bateman noted that a strong recovery was on the cards for this month.

The miner was trading at about $1 020 per two-element ounce, which comprised 78% palladium and about 22% platinum.

Meanwhile, one of the two furnaces at the miner’s PGM processing facilities, in Columbus, Ohio, was expected to come back on line in early December, with operations expected to restart in mid-December.

Bateman explained that the ore fed from the mines increased the copper/nickel levels.

“That gives us a cost advantage in the recycling business, as we’re not having to purchase additional materials to recycle to autocatalysts,” he said.

The processing facility currently had a high recovery rate of 99.8% for PGMs, and only rans for four days a week.

Bateman said electric furnace No 2 would soon be expanded when it was rebuilt.

He explained that this was required as a result of the Blitz expansion and would increase the capacity to catch up after a rebuild.

“We’ve got a good feeling about the quality of Stillwater . . . and we think that the pain we are taking in terms of current leverage, and so on, was well worth [it] in acquiring this asset,” CEO Neal Froneman commented.

South Africa

Sibanye was also looking forward to closing the buyout of fellow South African platinum mining company Lonmin and integrating it successfully into its operations.

The Competition Tribunal’s hearing on Sibanye-Stillwater’s proposed acquisition of Lonmin had been rescheduled for the week of November 12, with a ruling anticipated before the end of this month.

The company, meanwhile, remained focused on deleveraging and getting its gold business performing again, while not letting its PGM assets underperform.

The significant operational challenges experienced at the South African gold operations during the first half of this year, and the additional safety improvement interventions that were undertaken, continued to affect productivity across the gold operations in the third quarter.

Driefontein, in particular, delivered substantially reduced production rates.

As a result, adjusted earnings before interest, taxes, depreciation and amortisation (Ebitda) for the South African gold operations for the third quarter were substantially lower than for the comparable period in 2017, with an elevated AISC.

As a result of the reduced contribution from the South African gold operations during the period and the deferral of September sales to October at the US PGM operations, group adjusted Ebitda plummeted by 40% to R1.6-billion.

Contributions from group PGMs operations to group adjusted Ebitda increased to 85%, compared with 49% in the prior comparable period.
