Lithium in Pakistan: What We Actually Know About the Pegmatite Belts

Three weeks ago I was standing on a ridge above Shigar valley, looking at a tourmaline-rich pegmatite dyke that locals have been chipping at for gemstones since the 1970s. The dyke is roughly 4 meters wide. Nobody had ever tested it for lithium.

That's the state of lithium exploration in Pakistan right now. Pegmatites everywhere. Assays almost nowhere.

And honestly, that's both the problem and the opportunity.

The pegmatite belts nobody is talking about loud enough

Pakistan has three serious pegmatite provinces. The Northern Pakistan belt running through Gilgit-Baltistan — Skardu, Shigar, Stak Nala, Braldu, Haramosh. The Chitral-Swat zone in KP. And the smaller but interesting Mansehra granite-related pegmatites further south.

Most geologists outside Pakistan only know these from the gemstone literature. Aquamarine. Tourmaline. Topaz. The GSP has documented over 200 pegmatite occurrences in the Shigar-Braldu area alone. But the documentation focuses on gem potential, not on the boring stuff that actually matters for battery supply chains — spodumene, petalite, lepidolite, amblygonite.

Here's the thing. Where you find clean gem tourmaline and beryl, you very often find LCT-type pegmatites. LCT means lithium-cesium-tantalum. These are the same chemical fingerprints that produced Greenbushes in Australia and Manono in the DRC.

I'm not saying Shigar is Greenbushes. I'm saying we don't know yet because nobody has properly looked.

What the satellite data is actually showing us

At GeoMine AI we've been running Sentinel-2 and ASTER stacks across the Northern Areas pegmatite belt for the better part of two years now. A few things worth sharing.

Pegmatites are tricky targets from space. They're narrow (often 2-20 meters wide), and most satellite pixels are 10-30 meters. So you're rarely seeing the dyke itself. You're seeing the alteration halo, the muscovite-rich wall rock, the K-feldspar weathering signature, and sometimes the topographic expression where a resistant pegmatite stands up above the schist around it.

Sentinel-2's SWIR bands (11 and 12) pick up muscovite reasonably well. ASTER does better on the AlOH features around bands 5-6. When we combine those with SRTM-derived ridge extraction and structural lineament mapping, we can narrow down pegmatite-favorable zones from thousands of square kilometers down to maybe 40-60 priority targets in a district.

That's not a discovery. That's a shortlist. Big difference.

The actual lithium content still needs ground sampling and XRF or ICP-MS. No satellite on earth can tell you a pegmatite is spodumene-bearing without ground truth. Anyone selling you that is lying.

I used to think hyperspectral would be the answer here. Then I spent six months testing PRISMA scenes over Shigar and realized the swath coverage and cloud issues make it borderline useless for systematic exploration in mountain country. Multispectral with smart processing wins on practicality.

Where the assessment status actually stands

Let me be blunt about what exists and what doesn't.

What exists: GSP reconnaissance reports from the 1980s and 90s describing pegmatite mineralogy in qualitative terms. A handful of academic papers (Kausar, Khan, and others) that mention lithium minerals in passing. A 2023 preliminary screening by SUPARCO that flagged some Skardu pegmatites. The Reko Diq and Saindak attention has sucked most of the exploration oxygen out of the room for the last decade.

What doesn't exist: a systematic, drill-tested lithium resource estimate anywhere in Pakistan. Not one JORC or NI 43-101 compliant lithium resource. Zero.

Compare that to neighbors. Afghanistan has USGS-documented lithium occurrences in Nuristan and Badakhshan that are geological extensions of the same Hindu Kush pegmatite system that crosses into Chitral. The rocks don't care about borders. The data gap does.

So when people ask me "how much lithium does Pakistan have?" — I genuinely don't know. Nobody does. The honest answer is that we have geologically permissive ground covering maybe 15,000 to 20,000 square kilometers across the northern pegmatite provinces, and a sampling density that's less than 1 site per 100 km² in most of it.

That's not an exploration program. That's a starting line.

What needs to happen next

A few things, in order of how cheap they are.

Reprocess existing satellite archives properly. Sentinel-2 has been free since 2015. There are 200+ usable scenes over Gilgit-Baltistan that have never been touched for lithium-specific spectral targeting. This costs almost nothing if you have the right pipeline. We've been doing this at geomines for our internal targeting and it's where I'd start if I were a provincial mining department.

Follow up with focused stream sediment sampling. Lithium is mobile in surface water. A few hundred well-placed sediment samples across the Shigar, Braldu, and Hushe drainages would tell us more than any amount of remote sensing alone.

Then, and only then, start trenching the priority dykes. Drilling comes much later.

The whole sequence — from satellite reprocessing to first drill program — should cost under $4 million for a serious district-scale assessment. The Punjab and KP mining departments spend more than that on conferences in a year.

Look, I own 15 mines in GB. None of them are lithium projects, at least not yet. But I've walked enough pegmatite outcrops in Shigar and Stak Nala to know there's something real here that the country is sleeping on while the world is paying $20,000+ a ton for battery-grade lithium carbonate.

The rocks have been there for 50 million years. They'll wait. But the market window for being early on Pakistan lithium deposits — that's measured in maybe 3 to 5 years before the easy ground gets claimed.

So who's actually going to go look?
