For nearly four decades we've put boots on the ground across the Sierra Nevada and the Great Basin — reading the rocks, staking claims, and helping people find their fortune in the earth.
Advanced Geologic Exploration, Inc. opened its doors in Chester, California in 1987. Since then we've grown into a full-spectrum earth-science firm: gold & mining claims, mineral exploration, water resources, environmental compliance, and natural-hazard studies.
What's never changed is the approach — real fieldwork, careful documentation, and straight answers. We're big enough to run a corporate drilling program and small enough that you'll actually talk to the geologist doing the work.
Advanced Geologic Exploration, Inc. opens in Chester, California — a full-service geological consultancy built on real, boots-on-the-ground fieldwork.
Services expand well beyond gold — water resources, environmental compliance, geohazards and construction-materials testing for clients across the West.
A field office in Tonopah, Nevada extends our reach across the Great Basin's mining districts and desert claims.
We build a reputation for honestly-represented, field-verified mining claims — and the filing & maintenance help that keeps them in good standing.
Over 150 placer & lode claims sold in recent years with 97% buyer satisfaction — still led by Chief Geologist Charles P. Watson and 45+ years of experience.
A small, senior team that answers the phone and shows up in the field. Yes — the security supervisor is a German Shepherd.
Forty-five-plus years of academic and professional geology across mining, water and hazards. Charles runs every project like a tactical mission — plan, execute, document — and personally stands behind the science that goes out the door.
Bookkeeping, scheduling and the friendly voice that keeps the whole operation running.
Front desk, client wrangling and the hands behind the company's web presence.
Four legs, zero tolerance for trespassers. Guards the office and supervises morale.
Our very own guardian angel — rest in peace. Still watching over the crew.
We don't work from a desk. Every claim and report is backed by mapping the ground in person.
Plan, execute, document. Clear records and reports that hold up to a board, a bank or a regulator.
Straight talk about what ground is worth, what a claim is, and what it isn't. No hype.
Serious science, run with genuine enthusiasm for the earth — and a little personality.
It's on our wall and it's how we work: better science, better service, better results — from a team that genuinely loves reading the earth.
Based in California's Lake Almanor gold country, with a field office in the Nevada Great Basin. We serve projects across California, Nevada and Arizona.
Claims, consulting, or just a question — we're glad to help.
