Hochschild Mining stock sank 19% after Mara Rosa halt, cuts output guidance

Hochschild Mining shares fell over 19% after the company suspended operations at its Mara Rosa mine in Brazil for six weeks due to technical and weather-related issues, leading to a significant cut in full-year production guidance; the company now expects 71,000 ounces of gold production from the site, a 24% drop from the market consensus of 93,000 ounces. RBC Capital Markets estimates this production downgrade will reduce full-year EBITDA by $25 million, about 4% of current consensus forecasts, and makes a production recovery in the second half of the year more challenging, especially following the recent resignation of the company's COO.

Analysis

Hochschild Mining (HOCM) experienced a significant share price decline, tumbling over 19%, following the announcement of a six-week operational suspension at its Mara Rosa mine in Brazil. This suspension, attributed to ongoing technical issues, specifically with the filter system, and weather-related problems including heavy rainfall and contractor performance issues flagged in Q1, has necessitated a sharp cut to full-year production guidance. The Mara Rosa mine had produced 25,000 ounces of gold as of May, approximately one-quarter of its original annual guidance of 94,000 to 104,000 ounces. RBC Capital Markets now projects Mara Rosa's output at around 71,000 ounces, a 24% decrease from the market consensus of 93,000 ounces. This revision reduces Hochschild’s expected total group production for the year to 337,000 ounces, falling below the lower end of the company's guidance range (340,000 to 375,000 ounces). The situation is compounded by the recent resignation of Chief Operating Officer Rodrigo Nunez, making a second-half production recovery more challenging. Cost estimates are also under pressure, with RBC's all-in sustaining cost (AISC) estimate for Mara Rosa at $1,373 per ounce, slightly above the company's $1,287-$1,370 range, and broader market estimates at $1,428 per ounce. RBC calculates that this production downgrade, at a consensus gold price of $2,575 per ounce and an assumed cash cost of $1,428, could reduce full-year EBITDA by $25 million, equating to approximately 4% of current consensus forecasts. Operations at the company’s other mines, Inmaculada and San Jose, however, remain in line with guidance, providing a degree of operational stability elsewhere in the portfolio.

Key Decisions for Investors

• Investors should exercise caution given the significant operational setbacks at the Mara Rosa mine, the substantial downward revision in its production guidance, and the consequent negative impact on projected group output and earnings.
• Closely monitor updates on the six-week suspension timeline, the resolution of technical and weather-related issues at Mara Rosa, the company's ability to manage contractor performance, and any developments regarding the COO succession, as these factors are critical to assessing the potential for a second-half recovery.
• Re-evaluate investment positions in Hochschild Mining in light of the heightened operational risks and cost pressures at a key asset, while acknowledging that the stable performance of the Inmaculada and San Jose mines offers some mitigation but may not fully offset the challenges at Mara Rosa.
