Atalaya Adds Two Spanish Copper Projects as Its Growth Pipeline Competes for Capital

Atalaya Mining has acquired two former mines in southern Spain for €125 million, adding a substantial mineral inventory to a business that already has several projects seeking capital. The purchase comes as its operating Riotinto complex is benefiting from higher copper prices, giving Atalaya greater capacity to advance those assets. The near-term obligation is clear: €75 million has been paid and a further €50 million falls due within a year. The cost and timetable for bringing the acquired deposits back into production are still to be established.

The transaction extends the story in AER’s October assessment of Riotinto’s improving copper recovery. That analysis focused on extracting more copper from existing infrastructure. The new question is how much of Atalaya’s stronger balance sheet can be committed to longer-dated growth while it develops ore sources and advances Touro.

What Atalaya bought

Atalaya operates Proyecto Riotinto, an open-pit copper mine and processing complex in Andalusia. It mines ore, concentrates the copper and sells the concentrate, so production, metal prices and treatment terms determine much of its revenue. Its regional knowledge is relevant to Tharsis and La Zarza: the acquired properties lie approximately 50 kilometers and 25 kilometers west of Riotinto, respectively, in the Iberian Pyrite Belt.

On November 11, Atalaya completed the purchase of all shares in Tharsis Mining, the private owner of both projects, from members of the López Magdaleno family. Mining at Tharsis stopped in 2001 and at La Zarza in 1991; historical operators mainly extracted pyrite for sulfuric acid. Both deposits also contain copper, zinc, lead and precious metals, which could support more than one revenue stream if they can be processed economically.

The €125 million price comprises €75 million in cash paid at completion and €50 million payable within 12 months. The deferred amount is secured by a bank guarantee and bears interest at 12-month EURIBOR plus 1.5 percentage points. Identified legacy and contingent liabilities, estimated at approximately €7 million, remain obligations of the acquired group. Atalaya issued no shares for this transaction.

The company reported more than €260 million of pro forma net cash after the upfront payment. That figure precedes the deferred consideration. Subtracting the €50 million principal alone implies more than €210 million on the same illustrative basis, before interest, the identified liabilities and any other intervening cash flows. This is a way to size the obligation, not a forecast of cash at its payment date.

A large resource, with work ahead

The disclosed resource estimates give the purchase scale. The acquisition announcement’s project tables report the following figures; totals combine measured, indicated and inferred categories.

The copper is estimated to be in the ground, not the amount that can necessarily be recovered and sold. Inferred resources have lower geological confidence than measured and indicated resources, and the combined figures are not a statement of mineral reserves. Mining plans, metal recoveries, permitting and costs will determine how much of the inventory can support an economically viable operation.

There is useful technical work to build on. A 2023 preliminary economic assessment for Tharsis examined a five-million-tonne-per-year open pit and hydrometallurgical processing, which uses chemical solutions to recover metals. It is an early-stage assessment, not a construction commitment. Atalaya plans further studies, engineering, permitting and exploration; it has not disclosed a current capital budget or production schedule for the acquired projects in the purchase announcement.

Proximity to Riotinto may provide access to regional skills and infrastructure, and management expects potential operational and administrative synergies. The announcement does not establish that ore from either acquisition can be processed at Riotinto’s existing plant or quantify savings. The processing route is consequential because transport, recovery and plant investment can materially alter the value of a polymetallic deposit.

Higher prices lift operating earnings

Atalaya’s November 12 results and interim financial statements show why it could pay cash for the acquisition. Riotinto is the group’s operating mine, making the consolidated results a useful guide to the business currently funding its development pipeline.

Revenue increased by 75.9%, while reported EBITDA margin rose from 28.8% to 48.0%. Atalaya’s average realized copper price, excluding quotational-period adjustments, increased to US$6.44 per pound from US$4.41. Copper contained in concentrate sold rose to 15,243 tonnes from 12,234 tonnes, helped by sales from inventory. These are reported U.S.-dollar price measures; the financial statements are in euros and no currency conversion is assumed here.

The cost side also rose. Mine-site operating and administrative costs increased to €88.3 million from €71.1 million, while mine-site depreciation and amortization rose to €16.2 million from €14.0 million. Group operating profit follows after corporate expenses, share-based benefits, exploration and other income. Atalaya’s reported EBITDA is a different measure from IFRS operating profit; adding back the €16.2 million of mine-site depreciation and amortization brings the latter to approximately €90.1 million.

Higher prices should not obscure the operating mix. Third-quarter copper production increased to 13,967 tonnes from 12,123 tonnes as a higher ore grade and recovery offset lower ore throughput. For the first nine months, however, output fell to 37,399 tonnes from 39,589 tonnes, mainly because the ore grade was lower. Atalaya still expects full-year production near the low end of its original 50,000–54,000-tonne range. Reaching 50,000 tonnes would require 12,601 tonnes in the fourth quarter, compared with 13,967 tonnes in the third.

Cash available for competing projects

Earnings have translated into cash, though the timing differs. Third-quarter cash generated before working-capital changes was €94.8 million; net operating cash flow was €57.0 million after those movements, taxes and interest. A €52.2 million increase in trade and other receivables absorbed cash, partly offset by a €6.2 million inventory release and an €11.1 million increase in payables. The receivables movement is material when assessing how quickly sales fund investment.

For the nine months through September, operating cash flow was €165.6 million and investing outflows were €69.7 million. The latter included spending on existing projects and an investment in Lara Exploration; it was not solely mine construction. Financing activities provided a net €93.4 million, including €150.2 million of gross share issuance proceeds, €5.3 million of issuance costs, net borrowing repayments and €18.5 million in dividends. Stronger operations and earlier equity financing therefore both contributed to liquidity.

At September 30, before the acquisition, cash was €354.1 million and borrowings were €11.9 million, giving reported net cash of €342.1 million, excluding lease liabilities. The quarter-end figure and the later pro forma figure have different dates and should not be treated as a continuous cash bridge without the intervening movements.

The company’s other plans will also draw on management attention and capital. At Riotinto, it is investing in the San Dionisio area and preparing access development at Masa Valverde. In northwest Spain, Proyecto Touro remains in permitting, with its environmental impact statement awaited. Atalaya has a phased agreement to earn up to 80% of Touro’s owner, subject to milestones; the economics attributable to Atalaya will depend on that ownership and the project’s eventual funding.

Management expects the new acquisitions to be sequenced after Touro’s development. That gives Atalaya time to study the deposits, but it also places the new investment behind projects with nearer-term demands. Its €52 million–€80 million guidance for 2026 non-sustaining capital investment relates to the existing program and is not a disclosed development budget for Tharsis or La Zarza.

For investors, the immediate markers are the deferred payment and Touro’s permitting progress. The more decisive longer-term evidence will be Atalaya’s studies of recovery, processing and capital needs at Tharsis and La Zarza. Those figures will show whether the acquired resources can generate returns sufficient to compete for capital with the company’s existing projects.
