RehabLedger security for the transition economy

Engine room

Upload. Compute. Twelve questions, then stop.

Drop a PDF report, spreadsheet, GIS package, or AutoCAD file. The engine answers a short interrogatory — about a dozen questions, fifteen at most. To retain a position or run a full estimate, engage and pay.

Mining companies

What should we lodge, on which tool version, and what is already held? Remaining liability is stated only where remaining work is evidenced. Accounts stay apart from the regulator’s assessed deposit.

Banks & surety

Instrument type, principal, issuer, beneficiary, restricted cash, staged funding, expiry. A rehabilitation provision in the accounts is not a bond you can call.

Regulators

Current official rates and workbooks, historic estimates left intact, evidence for progressive rehabilitation and completion. Disagreement is recorded, not overwritten.

Enviro & engineering

Quantity × rate × modifier + allowances, exposed line by line. Scenarios labelled. Offsets scored on the Guide, not confused with the cost of works.

    Gated adapters refuse unofficial rates. A reprice of old quantities at new rates is a scenario, not an assessed deposit. A historic estimate is not remaining cost. Missing quantity or missing rate means that figure is unavailable.

    What the engine is built on

    Case types only. Named operations, counterparties, and dollar figures are confidential and are not shown.

    NSW base metals mine

    Underground base metals. Rehabilitation cost estimate, assessed security, lodged instrument, and accounts provision held as four dated objects.

    Copper comparison. Progressive rehabilitation and closure planning and financial assurance — not the NSW rate workbook.

    Black-throated finch offset

    Land-based Commonwealth offset for southern black-throated finch and related matters in North Queensland.

    Central-western NSW mining precinct

    Regional setting around the base-metals case. Not a second copy of that mine’s security.
