Precious-metal mining isn't exactly known as a high-growth industry. However, following years of conservative spending, and after witnessing gold and silver spot prices soar in 2019, miners like First Majestic Silver (NYSE:AG) are suddenly sitting pretty. Even before gold and silver moved higher by a double-digit percentage in response to falling U.S. Treasury yields, First Majestic was making waves. In May 2018, it closed a deal to acquire Primero Mining and its flagship San Dimas mine. Between incorporating the low-cost San Dimas into its portfolio, and looking at ways to bolster its existing assets (e.g., modifying the roasting circuit at its La Encantada mine to add up to 1.5 million ounces of silver production per year), First Majestic has seen its silver equivalent ounce (SEO) production grow from 16.2 million ounces in 2017 to perhaps north of 26 million SEO in 2019.
