Six review lanes for a lithium asset file
Huayou International Lithium (Hong Kong) Limited keeps six standing lanes in its Hung Hom vault. Each lane is a method, a set of records and a written output, and each can be engaged on its own or joined to the others when a holder needs one coherent file instead of six separate opinions.
Claims Ledger Bays
The claims ledger is the ground floor of every other review, because a file that cannot show where the ground sits cannot support a tonnage, a shipment or a sale. Claims Ledger Bays takes the full set of mineral claims, licence blocks and recorded boundaries held by a client and assigns each one a numbered bay in our vault. Every bay carries the recorded claim identifier, the grant and expiry dates, the registered holder, the boundary geometry as recorded and any known encumbrance such as a royalty or a partial assignment. We then reconcile the bay record against the public register and against the map the client has been using in its own materials.
Disagreement is common, and it is not usually dramatic. A boundary recorded in degrees and minutes may drift twenty metres against a boundary recorded in decimal degrees, and that drift can pull a collared hole outside the claim line. A licence may have been renewed in a name that differs slightly from the trading name used in an offtake note. A block may carry a caveat that was never picked up when the asset was transferred between two group companies. The bay method exposes each of these because the record is entered once and checked three ways: against the register, against the client map and against the geometry in the drilling file.
The output of this lane is a ledger table with one row per bay, a boundary overlay drawing and a short written note naming any claim where the register and the client map do not agree. Holders use that ledger as the base for due diligence, for a joint venture pack or for the claims schedule attached to a shipment booking. We also keep a change log for each bay, so a renewal or a partial surrender can be traced to the date it was entered rather than reconstructed from memory.
Assay Report Runs
Assay certificates are usually stored as single sheets and read the same way, one page at a time. Assay Report Runs treats them differently. We assemble the certificates from a programme into a chronological run, then read the run as a whole. That change of view is where most of the value sits. A run will show whether the laboratory methods changed midway, whether the check samples held their tolerance, whether the standards behaved as the certificate claims, and whether the reported grades sit in a pattern that matches the geology logged at the time.
The lane begins with an intake check: certificate number, sample number, hole number, depth interval, method, laboratory, date of receipt and date of report. We flag any certificate that cites a superseded method or a laboratory that is not accredited for the element concerned. From there we build a sample to depth index for each hole and look for the ordinary faults of a busy programme: samples that overlap, intervals that skip, a sample number used twice, a duplicate that was never reported. Each finding is entered against the certificate that carries it, so the note never floats free of its evidence.
We finish with a run summary that states the range of grades, the consistency of the check programme and the level of confidence we would attach to the assay base if it were used in an estimate or an offtake note. Where a run is clean we say so in plain terms; where it is not, the summary names the specific certificates that need to be re-run or explained. Clients often bring the Assay Report Runs output straight to their laboratory for a follow-up, which shortens the cycle considerably.
Offtake Note Desks
An offtake note is a promise about material, and a promise is only as strong as the file behind it. Offtake Note Desks compares the note against the assay base, the tonnage schedule and the tenement position, so the obligation in the document matches what the programme can actually deliver. Tariff tables for each desk sit on the same shelf as the notes, and the review keeps them in sight. We read the note in two passes. The first pass reads it as a document: parties, term, quantity, specification, pricing basis, delivery point, quality adjustment and termination rights. The second pass reads it as an obligation: can the quantity be met from a claim the holder controls, at the grade the specification requires, within the window the note names, through the delivery point the note names.
The two passes often produce different pictures. A note may set a specification that the assay run can meet in the higher grade zones but not across the whole schedule, or a term that outlasts a tenement the holder has not renewed. We write those findings into a comparison table with two columns, what the note promises and what the file supports, and a short paragraph for each line where the two differ. That table is the most useful thing a trading desk can carry into a negotiation, because it tells them which of their promises is already safe and which still needs a document behind it.
Where a note is still in draft we will sit with the holder at the desk and mark the clauses that need work. We do not draft legal terms and we do not act as counsel; we supply the factual comparison the drafting team needs. At the close of the lane the desk file holds the note set, the comparison table, the assay references used and a note of any item held open pending a certificate or a renewal.
Tenement Status Windows
Tenement rights move on a calendar, and most of the risk in a lithium file sits in that calendar rather than in the geology. Tenement Status Windows keeps a live view of each tenement: grant date, expiry date, renewal filing window, expenditure commitment, reporting obligation and any encumbrance recorded against the title. Each window is set to open well ahead of a filing deadline, so a holder sees the renewal before it is urgent rather than after it has lapsed.
The lane works from the register first and the client correspondence second. We do not rely on a summary sheet prepared years ago if the register says something different today. Where a renewal has been filed we trace it through to the date it was recorded, and where an expenditure commitment has been reported we check it against the programme of work lodged with the authority. The windows also carry the practical items that never appear on a title document but decide whether work can proceed: land access arrangements, heritage clearances, water licences and any native title agreement that governs the ground.
Output is a status sheet for the current quarter, a calendar of the next four quarters and a one page note on anything that needs action within thirty days. Holders on the other side of a transaction use the status sheet as a condition precedent tracker; operational teams use the calendar to plan work programmes. We refresh the windows at the start of each quarter for clients on a continuing arrangement, and on demand for clients who hold a standing file.
Resource Estimate Reviews
A resource estimate is a conclusion drawn from a long chain of evidence, and the chain can only be tested by rebuilding it. Resource Estimate Reviews starts from the underlying drill and assay file and reconstructs the estimate inputs: the collar and survey table, the assay base, the domaining method, the top cut, the variogram, the block model dimensions and the classification boundaries. We do not produce a statutory estimate and we do not sign one. We test whether the stated tonnage and grade can be reached again from the same evidence, and we report where the rebuild diverges from the published number.
Divergence is not proof of error. It is a question that deserves an answer. A difference may come from a legitimate change in the top cut, from a refined domaining decision, or from a denser sample set that arrived after the original estimate. What matters is that the file can explain the difference in writing. Where it cannot, the review names the specific input that moved the number and asks for the supporting note. That is the practical test a technical reader applies, and it is the test we apply too.
The lane closes with a rebuild summary, a variance table by domain and a short set of questions for the estimate author. We also keep a copy of every input file we used, with its version and date, so the rebuild can be repeated exactly if a later estimate is issued. For holders preparing to sell a stake, the rebuild summary is often the document that turns an argument about numbers into a conversation about assumptions, which is a far more productive place to be.
Shipment Booking Sittings
When material is ready to move, the paperwork has a way of multiplying. Shipment Booking Sittings brings the loading window, the quay allocation, the bill of lading instructions, the assay certificate set, the packing list and the origin documents into a single sitting so the whole pack is read against the vessel plan at once. The sitting is a working session, usually held at the Hung Hom office with the holder, the freight forwarder and the trading desk on the line, and it ends with a signed off booking sheet.
We begin with the loading calendar and work backwards. A vessel slot that looks comfortable on a spreadsheet can become impossible once the assay certificates for the lot are due, the packing list has to be verified against the warehouse tally and the origin documents have to clear a customs broker. The sitting maps each dependency to a date and a responsible party, then walks the pack item by item to confirm it exists rather than to assume it will exist. Anything missing goes onto the open items list with an owner and a deadline.
The closing booking sheet records the lot identifiers, the quay, the window, the document set reviewed and the open items accepted by the holder. It is not a shipping instruction and it is not a customs filing; it is a factual record that the pack was read together before the window opened. Holders who sit with us before the booking window tightens tend to lose far fewer days at the quay, and the record they keep afterwards answers the questions that always arrive a month after the vessel has sailed.
A single sequence behind all six lanes
The lanes differ in subject but not in discipline. Every engagement runs through the same sequence, and every finding inside a lane is tied to the document that supports it.
Scope
We agree which lanes are engaged, what records you will provide and who will read the output.
Intake
Documents arrive as one bundle, receive a bay number and are indexed before any review comment is written.
Run
Each lane is worked in the order the file demands, with findings logged against their source record.
Close
The file closes with a summary, a support table, a list of open items and a retention period agreed at intake.
