How to Validate a Mining Consultant's Report Using Satellite Data: A Checklist for Pakistani Mine Owners
Cross-check the report's mineral claims against publicly visible satellite signatures before you pay for drilling. That's the single fastest way to catch a padded or copy-pasted geological report. Satellite data won't replace a drill core, but it will tell you whether the consultant's story even holds together from space.
I own 15 mines in Gilgit Baltistan. I've read a lot of reports. Some were honest. Some were recycled from a different site with the coordinates swapped out. And the owner paying for them had no way to tell the difference.
So here's how to check one yourself — or at least know what to demand.
Why satellite data is your cheapest validation tool
Ground surveys are expensive and slow. A consultant can walk your ground for two days and write forty pages. You have no independent way to confirm what they saw.
Satellite imagery gives you a second opinion that the consultant didn't control. Sentinel-2, ASTER, SAR, and SRTM DEM data are captured by orbiting instruments on fixed schedules. Nobody can edit what the satellite recorded on a given date. That's the point.
Here's the thing — satellite data is great at some things and useless at others. It's strong on surface alteration, structural features, lithology (rock type at surface), and terrain. It's weak on anything buried deep, grade (how rich the ore is), and tonnage. If a report claims a precise gold grade from satellite data alone, that's a red flag. You can't read grams per tonne from orbit.
The validation checklist
Run the report through these before you commit money. You don't need to be a geologist for most of them.
- Coordinates match the ground. Plug the report's GPS coordinates into Google Earth. Does the described terrain actually exist there? Wrong valley, wrong river, wrong elevation — it happens more than you'd think.
- Dates are stated and recent. Every map or image in the report should carry a capture date and the satellite source. No date means no verification.
- The target mineral matches the local geology. Chromite shows up in ophiolite belts (Muslim Bagh, Waziristan). Lithium and gold have their own host rocks. If the claimed mineral doesn't belong in that geological setting, ask why.
- Alteration zones are shown, not just asserted. For copper and gold, the consultant should map alteration — the chemical weathering halo around a deposit. ASTER data shows this well. A report that claims porphyry copper but shows no alteration mapping is thin.
- Structural features line up. Faults and fractures visible in SAR and DEM data often control where minerals concentrate. The report's claims should sit near real structures, not random spots.
- Sample locations are plotted on a real map. Not a hand-drawn sketch. Actual coordinates on satellite imagery.
- Claims are hedged honestly. A credible report says 'indications of' or 'anomaly consistent with.' A report promising certainty from remote sensing is overselling.
- The consultant is named and reachable. You'd be surprised how many reports have no author you can call back.
Print this. Walk through it line by line with the report in front of you.
How to actually check the satellite data yourself
You can do a basic version for free. Here's the rough process.
| Step | Free tool | What you're checking |
|---|---|---|
| Confirm location | Google Earth | Terrain and coordinates match the report |
| Check surface rock/alteration | Sentinel Hub EO Browser | Colour and spectral anomalies at the site |
| Check structure and terrain | SRTM DEM / Google Earth | Faults, slopes, drainage patterns |
| Compare over time | Sentinel-2 archive | Is this site actually being worked or untouched? |
EO Browser (from Copernicus, the EU's satellite program) lets anyone pull Sentinel-2 imagery for free. It takes an afternoon to learn the basics. You won't produce a mineral map, but you'll confirm whether the consultant's described surface features are really there.
For the part you can't do yourself — the spectral analysis that separates alteration minerals from ordinary rock — that's where you need a specialist read. This is what we do at GeoMine AI (geomines.org). We run Sentinel-2, ASTER, SAR, and SRTM DEM data through AI models to generate an independent geological report. If your consultant's findings and ours disagree, that disagreement is worth more than either report alone. It tells you exactly where to spend your drilling budget to settle the question.
Common tricks a bad report uses
A few patterns I've learned to watch for.
Recycled reports. Same wording, same photos, different coordinates. Search a distinctive phrase from the report online. If it shows up attached to someone else's mine, you have your answer.
Grade claims with no basis. Numbers like '12 g/t gold' presented without drill assays. Surface samples and satellite data can show an anomaly — they cannot confirm a grade across your whole claim.
Confusing surface showings with reserves. A visible mineral outcrop isn't a reserve. Reserves require drilling, sampling, and a resource estimate under a recognised standard. Don't let a shiny rock photo stand in for that.
Vague boundaries. If the report won't tell you where the anomaly starts and stops, you can't size what you're buying.
Honestly? The most expensive mistake I see isn't fraud. It's a sincere consultant stretching weak surface data into confident conclusions. Satellite cross-checking catches both.
What to ask your consultant directly
Before and after you get the report, put these questions to them:
- Which satellite datasets did you use, and on what dates?
- Can you share the raw imagery or anomaly maps, not just the conclusions?
- What's the difference between what you confirmed from space and what still needs drilling?
- Would you stand by this report if a second remote-sensing analysis contradicted it?
A good mining consultant in Pakistan will answer all four without flinching. If they get defensive about an independent satellite check, that's information too.
Next step: pull up your report, open Google Earth, and run the eight-point checklist above tonight. If anything doesn't line up — or you want an independent satellite read before you drill — send us the coordinates and the claimed mineral at geomines.org and we'll tell you what our data shows.
