Acacia Mining loses £710m as Tanzania row leads to write-downs

The FTSE 250 group's revenue of $751.5m for the calendar year was down 29% on the previous year as gold production decreased 27% after Tanzania's mining authorities banned the export of gold-copper concentrate last March. This ban meant the company was unable to export and sell 185,800 ounces of produced gold during the year.

With the ban still in place as Acacia's 64%-owning parent company Barrick Gold finalises a resolution with the Tanzanian government, Acacia switched production at its Buzwagi mine from concentrate to gold doré bars, which are not affected by the export ban.

As it still awaits detailed proposals from Barrick over a proposed agreement for Tanzania to share the economic benefits on a 50/50 basis, in the form of royalties, taxes and a 16% free carry interest in the operating mines, Acacia has written down the carrying values of its mining assets, though still hoped its application for international arbitration could lead to an alternative solution to be negotiated.

In light of the potential reduction in value of all three of its operating mines, Acacia has took a $850m gross impairment charge, including a net $632m for the Bulyanhulu mine due to its longer mine life and the delay to a return to positive cash generation after its move to reduced operations. This saw the gross profit of $293m lurch into the sizeable pre-tax loss.

In addition to the above net impairment, Acacia also raised an additional tax provision of $172m relating to the estimated uncertain tax positions for its operating companies, based on an estimate of the impact of a comprehensive settlement, which brings total tax provisions to $300m in line with Barrick's pledge for it to pay back taxes.

Year-end cash, as had already been revealed last month, shrank to $81m from $318m, with net cash of US$10m as the new year began and so directors have decided not to pay a dividend.

“We delivered resilient operational performance during a challenging 2017," said Peter Geleta, interim chief executive after former CEO Brad Gordon and chief financial officer Andrew Wray both jumped ship in November after Barrick shook hands on its agreement with Tanzanian president John Magufuli.

Geleta, previously Acacia’s head of organisational effectiveness and a former executive at Canada-based Barrick, said the action taken during the year, including wringing out an all-in sustaining cost of $875 per ounce that was below the guidance range and the lowest that Acacia has ever achieved, he believes "operations are now well placed to deliver in 2018".

He went on: "As expected, we will see a step-down in production in 2018 to 435,000-475,000 ounces as Buzwagi transitions to processing stockpiles and Bulyanhulu, whilst in reduced operations, solely re-processes tailings. Our continued cost discipline means that AISC will remain competitive at US$935-985 per ounce.

"Our focus remains on delivering optimal performance from all aspects of the business within our control in the current operating environment, returning the business to free cash generation and delivering value for all of our stakeholders. We are supporting efforts towards achieving a negotiated resolution with the Tanzanian government.”

Acacia shares fell more than 9% to 155.75p after over an hour of trading on Monday.

While a resolution is hoped for in 2018, analysts at RBC Capital Markets noted that challenges continue, with the Ministry of Minerals seeking the restoration of the floatation circuit at the Buzwagi mine after its adjustment to a dore producer and clarification on "potentially applicable regulatory approvals" which ACA had not sought as it believed that these did not apply having conversed with relevant government agencies.

RBC felt 2018 guidance was a "little light" versus its estimate of 489koz production at AISC of $915/oz. "The main driver of the weaker production versus our estimate is Buzwagi, with production guided to 100koz vs. our 139koz, driven by our expectation of some better grades in H1 as the mine transitions into a stockpiles operation.

"Capex guidance stands at $100m, higher than our $50m estimate, due to higher guided capex at Mara and an additional $10m of plant adjustments at Buly."

Henry Croft, research analyst at Accendo Markets, said the dividend cut was the reason for the shares' decline.

"The dispute with Tanzania is now as long-running as it is well-publicised, 11 months after the stand-off over gold exports began after claims from Tanzanian President Magufuli that Acacia cheated the country out of tens of billions of dollars by understating the value of its exports," he said.

"With a backlog of shipments already lying dormant, it’s no surprise that total production has decreased by almost a third over the past year, suggesting that even when a deal is reached, the impact on Acacia’s mining capacity will be felt long into the future," Croft added, saying the cutting of the dividend will be the "final straw for many loyal shareholders who have stuck with the company in the hope a deal will be reached within the next five months".
