About AdAurum

Every claim, mine and map layer — in one place.

AdAurum pulls the scattered world of prospecting data onto a single screen, and it's completely free.

Why AdAurum exists

The information you need to prospect legally is all public — active mining claims, public versus private land, historic mines, geology and terrain. The problem is that it's scattered across a dozen clunky government sites and almost impossible to make sense of out in the field.

AdAurum exists to put all of it on one screen and make it dead simple to use. The aim is to help you find color without claim-jumping, without running into trouble with the law, and with the confidence that if you do hit the motherlode, you're somewhere you can actually stake a claim.

Is it really free?

Completely. Every feature and every map layer is free, for everyone — no paywalls, no "pro" tier, no credit card. There's nothing held back.

AdAurum is kept alive by optional donations and a handful of affiliate links to gear we'd actually recommend. That's it — so the app itself stays free for the whole community.

Getting the best out of the map

AdAurum is built so you can switch maps and layers on and off without ever losing your exact spot or zoom level. The trick is to experiment with different map and layer combinations until you've got exactly the detail you need for what you're doing.

If the screen ever feels busy, turn off the layers you don't need right now — especially the claims layer when you're reading terrain. Once you get the hang of it, it's quick and effortless.

Finding gold should be about the dirt, not the paywall. AdAurum is built in the field, for the field — and it's yours, free. Get out there and good luck.
