Wheaton Precious Metals CorpAntamina stream deal increases silver and gold production, driving growth
Wheaton Precious Metals Corp. has seen strong performance this year, driven by its new precious metals purchase agreement with BHP Group Limited. The $4.3-billion Antamina stream deal, effective April 1, 2026, is Wheaton's largest transaction, increasing its attributable silver to 67.5% and adding 33.75% of payable silver until thresholds step down, with ongoing payments equal to 20% of spot silver. Despite Antamina's second-quarter production falling short due to lower grades and a maintenance shutdown, the mine's silver output rose 56% year over year to 2.3 million ounces. Wheaton's attributable gold-equivalent production increased 13.8% to 414,755 ounces in the first half of 2026, and the company reaffirmed its 2026 guidance of 860,000-940,000 GEOs, expecting a 30% rise at the midpoint from 2025's 692,000 ounces. Wheaton projects 1.2 million GEOs by 2030, with the Antamina deal and new mines driving growth. Shares have jumped 43.5% in a year, and the Zacks Consensus Estimate for 2026 sales is $3.66 billion, up 58.1% year over year.
