The Costmine Intelligence Story
Costmine Intelligence is the product of decades of dedication from experts across multiple mining professions, stemming from the collaboration of two pioneering companies in the 1980s: Western Mine Engineering and InfoMine.
In 1983, Otto Schumacher, during his tenure at the Bureau of Mines in Spokane, recognized a demand for a detailed mining cost dataset. Faced with the challenge of sourcing the data, he created the Mining Cost Service, later joined by Jennifer Leinart and Scott Stebbins. Together, they expanded the database and launched the groundbreaking SHERPA software.
Meanwhile, InfoMine, established by Andy Robertson in Vancouver, launched the Companies and Properties database, initially distributed via floppy disks. The goal? To furnish quality mining data for industry professionals and investors.
Over time, the two companies fostered a cooperative bond. In 2006, as Otto looked towards retirement, InfoMine acquired Western Mine Engineering, newly minted as CostMine. Their combined expertise resulted in a synergistic growth, becoming the digital hub for mining enthusiasts. As the years rolled on, the Companies and Properties database evolved and expanded into what is now known as Mining Intelligence under the leadership of Katja Freitag.
Throughout all these transitions, the unwavering commitment of both companies has been to provide accurate and trustworthy mining data, backed by seasoned mining experts.
Our shared legacy and aligned values of Confidence in our data, Curiosity about technology and mining, and a Growth mindset geared toward the goal of building a better future for everyone in the mining industry that defines our direction and fuels our mission to deliver accurate and reliable mining data that empowers informed, data-driven decision making.
