Sociedad Punta del Cobre S.A

What it is

Pucobre is a Chilean mining company that explores and exploits copper in the Atacama Region — the same hyper-arid strip of northern Chile that holds some of the world’s richest copper deposits. Its assets include the San José copper concentrator, the Punta del Cobre, Granate, and Venado Sur mines, and the Biocobre cathode plant, producing two forms of refined copper sold to smelters and direct to export markets.

Pucobre was incorporated on 11 July 1989 as an open stock corporation under Chilean law, making it one of the older mid-sized copper producers listed in Santiago. It specialises in exploiting medium-sized copper deposits, with operations concentrated in the Atacama Region.

Who owns it

The largest single shareholder is Inversiones Lota Green SpA, with roughly 27% of the shares. The Hurtado Vicuña family, which controls Inversiones Lota Green, holds Pucobre alongside stakes in financial group Consorcio, cement maker Polpaico, and telecom holding Almendral — a classic Chilean industrial family portfolio.

Insiders in total hold about 79.9% of the shares, leaving a free float of roughly 20%, per structured data.

The group participates through Pacífico Quinta Región and its subsidiary Punta del Cobre S.A., a layered holding structure that concentrates voting power firmly in the family’s hands. Institutional investors hold a further ~12% (EODHD data).

Who runs it

Sebastián Ríos is CEO. He also serves on the board of Cementos Polpaico, another company tied to the same controlling group, and has been a Pucobre board member since 2017 — indicating the Hurtado Vicuña family relies on a small, trusted inner circle of managers across its businesses.

Fernando Harambillet serves as board president.

The money, in plain words

Sales have grown sharply: $308m in 2023, $376m in 2024, $509m in 2025 — a 35% jump in the last year alone (our calculation), driven by higher copper prices and rising output. The company keeps about 27 cents of profit from every dollar of sales — a net margin of 26.6% (TTM), strong for any mining company.

For every dollar shareholders have put in, the company earns back roughly 23 cents a year — a return on equity of 22.8%, comfortably above the cost of capital for most miners. The balance sheet holds $92m USD in cash with no separately disclosed debt at the parent level (our calculation; subsidiary project debt described below).

At 15.6 times earnings, the shares trade at a modest price-to-earnings ratio for a copper miner of this quality; the company pays no dividend, reinvesting cash into growth instead.

What it is doing now

The defining move: Pucobre and investment firm Resource Capital Funds closed a $375m senior-secured construction loan in January 2025 to build the El Espino mine in Chile’s Coquimbo region, which is expected to begin operating in 2027 and produce 26,000 tonnes of copper and 13,000 ounces of gold per year for roughly 18 years. This is described as the first greenfield copper project to be constructed in Chile in a decade.

El Espino will nearly double Pucobre’s copper production capacity, cementing its position as Chile’s leading mid-size copper producer. In March 2025, Pucobre created a new holding vehicle, El Espino Holding SpA, to hold its 76.32% stake in the El Espino joint venture — tidying the corporate structure ahead of construction ramp-up.

What to watch

• El Espino construction timeline. First production is targeted for 2027; any delay or cost overrun on this $375m project is the single largest risk to the investment case.
• Copper price. The tripling of profits since 2023 owes much to a copper price rally; a sustained drop would compress margins quickly at current volumes.
• Free-float thinness. With ~80% of shares held by insiders, trading volumes are low and minority investors have limited ability to influence governance.
• Dividend policy. The current zero yield reflects construction spending; watch for a payout resumption once El Espino reaches production.
