Administrative Group Assistant (Based in Napa, CA)

About the Company 

The mining industry has steadily become worse at finding new ore deposits, requiring >10X more capital to make discoveries compared to 30 years ago. The easy-to-find, near-surface deposits have largely been found, and the industry has chronically under-invested in new exploration technology, relying on the manual techniques of yesteryear – even as demand accelerates for copper, lithium, and other metals to build electric vehicles, renewable energy, and data centers.

KoBold builds AI models for mineral exploration and deploys those models—alongside our novel sensors—to guide decisions on KoBold-owned-and-operated exploration programs. In the six years since founding, KoBold has become by far both the largest independent mineral exploration company and the largest exploration technology developer. Our data scientists and software engineers, who come from leading technology companies, jointly lead exploration programs with our renowned exploration geologists.

KoBold has proven its first discovery with materially less capital than the industry average and found one of the best copper deposits ever discovered: the copper is far more concentrated than the global average of copper mines, and this asset alone is expected to generate meaningful revenue for decades. KoBold has a portfolio of more than 60 other projects, each of which has the potential for another high-quality discovery.

KoBold is privately held; investors include institutional asset managers T. Rowe Price and Canada Pension Plan Investments; technology venture capitalists Andreessen Horowitz, Breakthrough Energy Ventures, BOND Capital, and Standard Investments; and natural resources companies Equinor, BHP, and Mitsubishi.

KoBold Metals is seeking a proactive and detail-oriented Administrative Group Assistant based in Napa, CA to support our managers and leadership team. This is an excellent role for someone who loves keeping things organized, thrives in a remote environment, and takes pride in removing friction for others so they can focus on their most important work.

You will support day-to-day operations, coordinate logistics, and occasionally assist with in-person tasks for our CEO, in the Napa area — so living nearby is a plus. We’re looking for someone who is resourceful, eager to pitch in wherever needed, and sees no task as too small or unimportant.

This role is ideal for a self-starter who enjoys working independently, takes the initiative to anticipate needs, and has the drive to make systems run more smoothly.
