From Sample to Shipment: How a Serious Buyer Actually Sources Minerals from Pakistan

A trader from Ningbo emailed me last March asking if we could ship 500 tonnes of antimony concentrate within six weeks. No sample review, no assay verification, no site visit. Just a wire transfer and an expectation.

I said no. And I want to explain why, because that email is the exact opposite of how a real buyer should approach mineral sourcing in Pakistan.

Here's the thing — the buyers who actually close deals and get containers moving from Karachi are the ones who move slowly at the start and quickly at the end. The buyers who lose money (or never receive material) do the opposite. So let me walk through what a proper sample-to-shipment workflow looks like from our side of the table, with 16 concessions in Gilgit-Baltistan and enough closed transactions to know where things break.

Stage One: Sample, Assay, and the Boring Paperwork

Everything starts with a representative sample. Not a hand-picked lump of high-grade ore that photographs well — a properly quartered sample from an actual working face or stockpile, with GPS coordinates and photos of where it came from.

For a first engagement we typically ship 2 to 5 kg by DHL or FedEx from Islamabad. Larger bulk samples (50 to 500 kg for pilot metallurgical testing) move by air freight from Islamabad or Karachi, and those need an export permit even at sample volumes. That permit alone takes 3 to 4 weeks on a good run. I've had it take 11 weeks when the Mineral Department was reshuffling staff.

Buyers should always run their own assay. Always. We provide SGS or Bureau Veritas certificates from Islamabad or Karachi labs, but any serious off-take partner sends the sample to ALS Loughrea, SGS Tianjin, or their own in-house lab for a second opinion. Grade disputes at shipment stage are the single biggest reason deals collapse, and they're almost always preventable by doing dual assays at sample stage.

One detail people miss: for copper concentrate, ask for the full deleterious element panel — arsenic, antimony, bismuth, mercury, fluorine. A 24% Cu concentrate with 0.7% arsenic is a very different product from a clean 22% Cu concentrate. Smelter penalties will eat the margin.

Stage Two: Due Diligence That Actually Matters

Once assays agree within tolerance, the real diligence begins. Honestly, this is where I see the most confusion from first-time buyers into Pakistan.

What you need to verify:

• The mineral title itself. Every concession in Gilgit-Baltistan is issued by the GB Mineral Department under the GB Mining Concession Rules 2016. Ask for the lease number, area in hectares, coordinates, expiry date, and the current royalty status. We share ours openly — if a counterparty won't, walk away.
• Environmental and operational clearances. For any commercial-scale extraction you want to see the approved mining plan and the environmental NOC from GB-EPA.
• Export registration. The seller needs to be registered with FBR, hold a valid NTN, be a member of the relevant chamber of commerce, and ideally have prior export history you can verify through bill of lading records.
• Site visit. I know this sounds obvious. But maybe one buyer in four actually visits before signing an off-take. The ones who do almost always end up structuring better deals, because they understand the logistics reality — the KKH, the winter road closures above Chilas, the trucking capacity out of Skardu versus Gilgit.

We host buyers regularly. Chinese teams from Xinjiang cross overland via Khunjerab in summer. European and Gulf buyers usually fly Islamabad, then domestic to Skardu or by road up the Karakoram Highway. Plan five days minimum. Two of those will be travel.

Stage Three: Contract, LC, and the Shipment Itself

Once diligence is clean, contract structure matters more than price. I'll say that again because buyers under-weight it constantly. Contract structure matters more than price.

A typical off-take for concentrate from our operations runs on these terms: CIF Shanghai or FOB Karachi, monthly tonnage bands with a ±10% seller's option, payment by irrevocable LC at sight against shipping documents, provisional invoice at 90% on B/L, final settlement after CIQ or independent assay at discharge port. Umpire lab pre-agreed in the contract — usually Alfred H Knight or SGS.

For jade and granite (non-concentrate, dimensional or block material) the workflow is different. TT payment is more common, with 30% advance and 70% against B/L copy. Inspection happens at the yard in Skardu or at the Karachi port container yard before stuffing.

Logistics timing, roughly, from mine gate to vessel:

• Skardu or Bunji to Karachi port: 7 to 10 days by road in summer, 12 to 15 in winter
• Container stuffing and CHA clearance at Karachi: 4 to 7 days
• Ocean transit Karachi to Shanghai: about 18 days; to Rotterdam about 22; to Jebel Ali 5 to 6

So from the day a truck leaves our stockpile in GB to the day the container is on water, budget three weeks. First shipments always take longer. I tell every new buyer to add a two-week buffer on the maiden container and stop worrying about it.

What Usually Goes Wrong

A few honest patterns I've watched over the years.

Buyers rush the sample stage and then argue about grade at loadport. Buyers negotiate hard on price but ignore Incoterms and end up eating demurrage. Buyers assume Pakistan works like Chile or Zambia on export documentation and get surprised by the Mineral Department clearance layer that sits on top of federal customs.

And sellers — I'll be fair here — sellers oversell what's in the ground. I got this wrong myself early on. In 2019 I quoted an indicative grade on a molybdenum showing based on limited grab sampling, and the follow-up channel sampling came back materially lower. We had to reset the conversation with the buyer. Painful, but the relationship survived because we corrected it before contract, not after shipment.

So if you're evaluating Pakistan for critical minerals — copper, antimony, tungsten, moly, or the strategic side with jade and granite — the workflow isn't complicated. It's just sequential, and most of the pain lives in stages one and two. Get those right and the shipment almost handles itself.

What's the mineral you're actually trying to source, and how far along are you?
