Copper Concessions in Gilgit-Baltistan: Porphyry Geology, Grades and JV Structure

Last month I sat across from a copper buyer from Jiangxi who'd flown into Islamabad with one question: "Show me the assays, not the brochure." Fair.

That's how most of these conversations start now. The Reko Diq headlines from Balochistan have done their job — every commodity desk from Shanghai to Frankfurt now knows Pakistan has copper. What they don't know is what sits 800 km north, in the Karakoram and Kohistan arcs, where we hold ground.

So this is the assay-first version. No brochure.

The porphyry story, in plain language

Gilgit-Baltistan sits on the collision zone between the Indian and Eurasian plates. The Kohistan Island Arc — a Cretaceous-to-Eocene volcanic arc that got squeezed between two continents — runs right through our concession map. Arcs like this are how you get porphyry copper. Andean-style, more or less. The geological cousins are the deposits in Iran's Kerman belt and parts of southern Tibet.

We've got 16 concessions in total across the region. Four of them sit on copper-bearing ground, with three more under early-stage reconnaissance for porphyry and skarn-style mineralisation. The host rocks are mostly diorite to granodiorite intrusives cutting older volcanics — exactly what you want to see.

Honestly, when I first started walking some of these valleys in 2018, I thought we were looking at a straightforward vein system. I was wrong. The alteration halos — phyllic into propylitic, with patchy potassic at depth — told a porphyry story I hadn't read properly. Took a senior geologist from Quetta two days in the field to set me straight.

What the grades actually look like

Let me give you real numbers from rock-chip and channel sampling. Not inferred resources — we're pre-JORC on most of these blocks, and I won't pretend otherwise.

• Concession block near Chalt (Kohistan arc): rock-chip grades ranging 0.38% to 1.24% Cu, with one outlier channel at 2.7% over 1.8 m. Associated Au values of 0.2–0.9 g/t. Classic porphyry-style with secondary chalcocite enrichment near surface.
• Block in the Hunza valley corridor: disseminated chalcopyrite-pyrite in altered granodiorite. Average of 47 samples came back at 0.46% Cu. Lower grade, but the footprint is large — we've mapped surface alteration over roughly 2.3 km².
• Skardu district block: more of a skarn signature where intrusives meet carbonate. Grades patchier, 0.6% to 3.1% Cu, with meaningful Mo (up to 380 ppm) and silver credits.

For comparison, Reko Diq's reserve grade is around 0.41% Cu. Most operating porphyries globally sit between 0.3% and 0.8%. So we're in the conversation. Whether we're in the top quartile is what drilling has to prove.

Drilling. That's the gap. We've done trenching, channel sampling, and surface mapping. What we haven't done — and what no serious off-take buyer should commit on without — is a diamond drill program. That's exactly what a JV is supposed to fund.

How the licensing actually works in GB

This trips up almost every overseas party I talk to, so worth being direct.

Gilgit-Baltistan has its own mineral regime, separate from the four provinces. Licensing runs through the GB Department of Mines and Minerals under the GB Mining Concession Rules. Our concessions are held as mineral titles in good standing — exploration licences with defined coordinates, annual fees paid, and renewal pathways clear.

What we hold is the ground. What an incoming JV partner brings is capital, drilling capacity, and (in most cases) processing know-how. The legal vehicle is usually a Pakistani-registered JV company, with the foreign partner taking equity, and an off-take agreement layered on top if that's the structure they want.

Foreign direct investment into mining is permitted under SBP rules and the Board of Investment framework. Repatriation of dividends works. I won't pretend the paperwork is fast — it isn't — but it's navigable and we've walked partners through it before.

What a serious JV looks like

Here's the thing. I've had maybe forty inbound enquiries on copper alone since January. Maybe four of them were serious. The rest wanted exclusivity without commitment, or off-take pricing without drilling spend.

A workable Pakistan copper joint venture, in my experience, has three layers:

1. Earn-in phase. Partner funds a defined drill program — usually USD 3–6 million for a first-pass 4,000 to 6,000 metre program across the priority blocks — in exchange for a defined equity percentage. We've structured these at 25–40% earn-in depending on commitment depth.
2. Development phase. Pre-feasibility and feasibility studies, with the partner stepping up to majority equity if they choose to fund through to production.
3. Off-take. Concentrate off-take rights for the funding partner, typically at LME-linked pricing with treatment and refining charges negotiated against the concentrate spec.

The concentrate spec matters more than people think. Karakoram porphyry concentrate is likely to run clean — low arsenic, low fluorine — based on what we've seen so far in the sulphide mineralogy. That's a real commercial advantage for smelters in China and Japan who are increasingly fussy about penalty elements.

Logistics — the part nobody asks about until it's too late

Concentrate from GB moves by road down the Karakoram Highway to either Karachi port (roughly 1,700 km) or, for Chinese off-take, north through the Khunjerab Pass to Kashgar. The Khunjerab route closes in winter. Karachi runs year-round but the road haul is long and the trucking sector is fragmented.

For any JV, logistics capex needs to sit in the model from day one. We've costed concentrate trucking at roughly USD 95–110 per tonne to Karachi based on current diesel and contractor rates. That changes. But it's the order of magnitude you plan around.

If you're sitting in Shanghai or Hamburg or Tokyo and you've read this far, you probably already know the global copper picture — IEA projecting a supply gap by 2030, EV demand pulling 2.5 to 3 times more copper per vehicle than ICE, grid build-out in Europe alone needing millions of tonnes. The question isn't whether copper concessions Gilgit-Baltistan will matter. The question is who funds the drill rig first.

Drop me a note if you want the sample location maps and the assay sheets. The brochure version exists too, but I'd rather send you the spreadsheet.
