Built for Real Field Prospecting

Every feature in NuggetStrike is engineered for prospectors standing in creeks, scanning ridge cuts, and navigating remote public lands.

1m Bare-Earth 3DEP LiDAR

Strip away dense pine, oak, and manzanita cover. Our 1-meter high-resolution bare-earth hillshade reveals Tertiary ancient river channels, buried gravel benches, hydraulic pit escarpments, and fault traces that satellite maps miss.

USGS 3DEP High-Res

Multimodal Petrographic AI

Snap a photo of rock float, outcrop veins, or heavy mineral concentrates. Azure AI Vision analyzes crystalline quartz textures, hydrothermal ironstone gossan halos, and pathfinder sulfides like arsenopyrite, pyrite, and galena.

Azure AI Vision

Historical Mining Archives RAG

Direct semantic search across 140+ years of seminal surveys: Lindgren's Tertiary Gravels (1911), Knopf's Mother Lode System (1929), Ferguson's Alleghany Pockets (1932), and Clark (1970). Synthesized with exact volume and page citations.

Azure AI Foundry

BLM Unpatented Claims Radar

Stay strictly legal. Our real-time PLSS cadastral overlay verifies active vs. closed mining claims and USFS / BLM public domain boundaries to protect you from statutory mineral trespass under 43 CFR § 3809 and 36 CFR § 261.9.

Legal Trespass Shield

Hands-Free Voice Field Journal

Wet hands or swinging a metal detector? Tap dictate and speak naturally. Azure AI parses nugget weight, recovery tool, bedrock depth, and GPS coordinates into structured waypoints with text-to-speech confirmation.

Speech-to-Waypoint

Hydro-Geomorphic Placer Simulator

Model fluid stream dynamics, gravel bedload transport, and flood stage drop zones. Calculate inside bend point bar deposition, bedrock crevice capture ratios, and prime paystreaks based on stream gradient and hydrology.

Legal & Regulatory Notice: NuggetStrike is an economic geology and geospatial research tool. Mineral prospecting is governed by federal mining laws (30 U.S.C. §§ 21–54), BLM regulations (43 CFR § 3809), and USFS casual use rules (36 CFR § 261.9). Staking or recovering minerals upon valid unpatented claims held by third parties without authorization constitutes mineral trespass. Always verify local land status and county records before field operations.
