The Best Place to Mine for Critical Minerals is Where the Critical Minerals Are.
The hard part is proving where that is fast enough to matter.
Traditional detection workflows can stretch the time between sampling to action, especially when you’re trying to grid more ground, refine targets, or make near-term drilling and processing decisions.
Turn Invisible Chemistry into an Operational Advantage
More measurements, higher resolution
Unlimited samples mean unlimited resolution. Scale insight, down to ppb, without scaling complexity.
Easier sampling
No need to pulverize or combine multiple samples.
Faster feedback
Get results in days, regardless of the number of samples being tested.
Spatial understanding
Test cores directly to understand critical mineral distribution and variance below the surface.
Clearer data
Operationalize results faster with outputs that answer practical questions, like where to sample next, where to drill next, what to process next.
How it works:
We combine biological sensing with hyperspectral analysis, turning difficult-to-detect minerals into decision ready outputs. This enables teams to increase sampling density and get better results faster than traditional assays.
From Hidden Data to Value: How it Works
Our straightforward process fits into existing workflows without disruption—measure, map, mine.
Step 1
Apply
Fieldstone sensors are applied to relevant material (e.g., soil samples, cores, tailings) as part of a measurement run.
Step 2
Capture
A hyperspectral imaging pass captures the signal produced by the biosensors, configured for your workflow and environment.
Step 3
Analyze + Map
These signals are converted into interpretable data layers you can use to guide your next sampling or operational decision.
Detect the Signals that Matter
Fieldstone’s sensing library is built to identify specific chemical targets and translate them into high-resolution mapped outputs.
Today, mining-focused applications lead the way, and the platform can expand to additional targets as customer needs evolve.
Available now:
- Gold (Au)
- Copper (Cu)
- Arsenic (As)
In development:
- Silver (Ag)
- Molybdenum (Mo)
- Nickel (Ni)

Built for Every Stage of Mining
Fieldstone Bio provides precise measurement for critical minerals where speed and coverage determine what you do next.
Early Exploration
Faster screening and tighter targeting so you can sample smarter.
Exploration
Rapid indication of mineralization to prioritize follow-up and reduce wasted cycles.
Operations
Better visibility to support dump vs. process decisions and blending strategy.
Tailings/Waste
Re-check what’s been written off, monitor material movement, and help mitigate risk.
The result:
Slower iteration, less resolution, and higher uncertainty at the moments it matters most.
The cost:
Decision latency that leads to missed opportunity, and compounds across every phase of the program.
