Ten assessments, and what they taught us

A perimeter for construction limestone is offered in a national licensing round. The holder-to-be has the capital for the fee but no route to market beyond two local cement buyers.

Perimeter boundaries against the cadastral record; whether the resource statement is a historic estimate or a code-compliant one; haul distance to the nearest rail loading point; the real buyer list within economic haul range.

Resource figures come from a pre-1990 survey and are not reportable. Economics are decided not by grade but by the 38 km haul to rail — above roughly 60 km this material has no market at all.

Proceed, but on aggregates economics, not on a resource story. The value is the logistics position, not the rock.

Representation mandate on output, with the group funding a compliant resource statement in exchange for exclusivity on the first three years of sales.

A quarry that sells locally at the gate earns the gate price. The same quarry, put on rail with certified specification, reaches three countries.

A producing operation with decades of history sells almost entirely to domestic de-icing contracts, seasonal and concentrated in a handful of public buyers.

Production and delivery records against declared capacity; NaCl content and insolubles by lot; whether the product meets EN 16811 for road salt and the far stricter specifications for chemical and water-treatment use; port access at Constanța.

Quality is well above what the domestic de-icing market pays for. The producer is selling a chemical-grade product at road-salt prices because nobody has ever qualified it for the higher use.

Strong. The upside is in reclassification, not in more tonnes.

Offtake with a qualification programme: accredited assay campaign, sample submission to two industrial buyers, and a price formula that shares the uplift once the higher grade is accepted.

The same tonne, correctly qualified, changes market and changes price. Verification is the entire margin.

A graphite perimeter with historic workings is put back on the market. The seller's material speaks of the battery chain and of European critical-raw-materials policy.

Flake size distribution, not just carbon content; historic concentrate specifications; what the previous operation actually produced and why it stopped; distance to any existing processing capacity.

Carbon grade is respectable but flake distribution is dominated by fines. Fines serve refractories, not anode feed. The battery-chain story does not survive the size analysis.

Proceed on refractory economics. Refuse the battery narrative until spherical-grade testwork exists.

Staged: an option over the licence, exercisable only after a defined testwork programme, so the price is not paid for a market the material cannot enter.

Saying no to the story and yes to the rock is what separates a buyer from a believer.

A tailings facility from a closed metallurgical operation is offered as a low-capex reprocessing opportunity: the material is already mined, already crushed, sitting on surface.

Who legally holds the tailings and the liability attached to them; the environmental permit position; representative sampling across depth and area, not a single grab; recoverable metal by modern flotation, not head grade.

Metal content is real. The obstacle is that title to the tailings and responsibility for the closure obligation are not held by the same party, and neither is the party offering the deal.

Stop. Not a technical problem, a title problem — and the closure liability can exceed the metal value.

None until the holder of the environmental obligation is at the table. If they come, a processing contract with liability expressly retained by the site owner.

Most projects die on the assay. This one would have died on a permit — which is cheaper to find out first.

An alkaline complex with documented rare earth mineralisation is proposed as a European REE project, in a market where any European REE occurrence attracts attention.

Whether published work is exploration-stage or resource-stage; the split between light and heavy rare earths, since the value sits in a few elements and not in total oxide; mineralogy and whether the host mineral is treatable at all; where separation capacity exists in Europe.

The occurrence is genuine and geologically interesting. It is exploration-stage. And even a good concentrate has almost nowhere in Europe to be separated — the bottleneck is downstream, not underground.

Real, long, and not a trading opportunity. It is a development position.

Exploration agreement with staged earn-in and a first-refusal on future offtake. Money committed to drilling, not to acquisition.

Being early is only valuable if you pay early-stage prices. The discipline is refusing to pay a production multiple for exploration ground.

Six independent quarries within a hundred-kilometre radius each produce 80,000 to 200,000 tonnes a year. Public infrastructure tenders in the region require volumes and guarantees none of them can meet individually.

Each operation's licence validity and capacity, verified against delivery records; whether specifications are compatible enough to be pooled; the bonding and guarantee requirements of the tenders actually being lost.

Individually every one of them is disqualified on volume before quality is even examined. Together they clear the threshold with margin. The barrier is commercial and contractual, not geological.

The strongest structure on this list, and the least glamorous.

A commercial aggregation: each producer keeps ownership and independence and signs a representation mandate; the group bids as a single accountable counterparty, provides the guarantees, allocates volumes and pays each producer on delivery.

Ten operations that are individually unbankable become one counterparty that a public buyer can contract with. That is the whole business in one line.

A small operation produces lead-zinc concentrate and sells it ex-works to a single trader at a fixed discount, unchanged for years.

Assay by lot against the trader's settlement sheets; the payable terms actually applied; treatment and refining charges against current benchmarks; penalty elements and whether they are being charged correctly.

The contract applies penalties for an impurity that the last eleven assays show below the penalty threshold. The producer has been paying for a contaminant that is not there.

No new mine, no new market, no new tonne. Read the contract properly and the margin appears.

Renegotiation mandate with a success fee on recovered value, then an offtake on corrected terms with an umpire procedure.

A large part of what we do is not finding material. It is finding the money already being lost on material that is already moving.

A silica sand producer wants to move from foundry to glass. Glass pays materially more, and two rejected qualification attempts have already cost the producer a year.

Iron content lot by lot; whether iron is in the grain or in the coating, since one is removable by attrition and the other is not; the consistency of the product rather than its best result; the actual specification of the target buyer.

Average iron would pass. Variability would not. The buyer is not rejecting the average, they are rejecting the worst lot — and no glassmaker buys a product that is good most of the time.

Fixable, and worth fixing, but with process money rather than sales effort.

Technical assistance with a defined attrition and classification scope, paid against the qualified price once achieved. We are paid when it works.

Qualification with an industrial buyer is a discipline of consistency. Producers routinely sell the average and lose on the variance.

A gravel operation adjacent to a publicly funded road programme is producing well below capacity, while material for the programme is being imported.

Whether the operation is eligible to bid at all — registration, certification, guarantees; whether the product meets the technical specification written into the programme; who is currently supplying it and at what landed cost.

The material is compliant. The operation is excluded on procurement formalities it has never been shown how to satisfy, and imported material lands at a higher cost than local supply would.

The obstacle is administrative and is the cheapest kind to remove.

Representation and tender mandate: the group prepares the qualification file, provides the guarantee, bids, and subcontracts the supply back to the producer.

Access to a market is a product in itself, and it is the one small producers most often lack.

A bentonite producer sells a single undifferentiated product to whoever calls, at a single price, into three markets with completely different requirements.

Swelling index, moisture, montmorillonite content and rheology by lot; what drilling, foundry and civil-engineering buyers each actually specify; whether the deposit is uniform or zoned.

The deposit is zoned. Part of it meets drilling-fluid specification and commands a considerably better price; the rest is a civil-engineering product. Mixing them destroys the value of the better half.

Selective mining and two product lines, not one blended price.

Offtake on the premium fraction with a specification-linked price formula, plus technical support to separate the mining faces.

Blending a good product into an average one is the most common and most expensive mistake we see.
