- South32 (ASX:S32) to acquire a 45% stake in the Sierra Gorda copper mine in Chile, adding copper and molybdenum into its already highly diversified business.
- We are impressed with the strategy here, acquiring a non-operated interest in an asset that has had a troubled past (but better performance recently), getting S32 a cheap entry into one of the industry’s most sought after metals.
- US$1.6bn upfront cash payment, and US$500m in price/production linked payments (which won’t be triggered in our base case).
- Net debt of ~US$1.6bn post Sierra/Mozal acquisitions and dividend (0.6x EBITDA).
- We have not yet included the acquisition as some conditions precedent and pre-emptive option remain active. We maintain our Hold recommendation.
South32 (ASX:S32) has announced the agreed acquisition of a 45% non-operated interest in the Sierra Gorda copper mine in Chile from Sumitomo.
Upfront cash consideration of US$1.6bn, plus a further US$500m in contingent payments between 2022-25 (linked to copper price and production triggers).
We have not yet included the Sierra Gorda transaction in our base case given the 30-day pre-emptive period which KGHM could trigger, and typical approvals.
If completed, we would view the transaction as value (+A$0.38ps) and earnings accretive (+17% EBITDA) based on our modelling.
Sierra Gorda has a poor reputation, as a low-grade mine with a complicated mill. The operation experienced significant commissioning issues in 2014-15 with impacted production and heavy costs.
These days the asset is performing better, in FY21 producing (100%) 180kt copper, 5kt molybdenum, 54oz gold and 1.6moz silver, at an operating cost of US$1.29/lb (AISC ~US$2.00/lb). Medium-term unit cost guidance for an increase to US$1.30-$1.50/lb is partly driven by the mine currently operating above reserve grade at 0.48% Cu (reserve 0.40%).
Further upside to these numbers is possible if: 1) JV can de-bottleneck the plant, 2) Catabela is developed (1.45mt @ 0.4% Cu, 0.06gpt Au, 0.02% Mo), 3) resource growth from regional exploration, and 4) JV can cut down the heavy sustaining capex profile.
We view Sierra as a smart entry into copper. A robustly popular metal, S32 has been able to strike a deal to add meaningful copper production by going for an asset where it would share joint operatorship. Majors focus on acquiring interests that come with operatorship, while the dynamic also helps to get the price tag lower.
S32’s capable balance sheet can digest the acquisition. After the Sierra Gorda acquisition, Mozal acquisition, and October dividend payment, S32’s balance sheet is expected to move from US$660m net cash to US$1.5bn net debt. This is a very manageable 0.55x ND/EBITDA, with S32 not expecting its credit rating to change.

We have a strong positive view on the acquisition. While it may not be a tier 1 asset, it is producing healthy free cash flow with room for growth, in one of our favourite commodities.
While positive, the news plus earnings momentum has already seen S32 share price well supported. We maintain our Hold rating with a (login to view) target price.
Completing Sierra Gorda acquisition. Aluminium and coal price momentum.
