Financial Analysis — Tilden Mine

Mission: Bottom-up value and cost analysis for every Tilden initiative. Each card defines the formula and variables — the math structure, not necessarily the final number. Numbers are tagged by source: workshop-confirmed, estimated, or needs-corporate. This is the audit trail: every dollar in the business package traces back to a card here.

Methodology: Value per §3 of consolidation-plan.md (5-step: metric → current state → target → delta → sensitivity). Cost per §4 (effort-based: team composition × duration × rates).

Important: Tilden is a MINE, not a steel mill. Value drivers are reagent spend, ore recovery, fleet lifecycle, pellet quality, and logistics — not throughput per heat or coil quality. Mining equipment costs are higher per unit ($12M trucks, $30M shovels, $70K tires) and the operational environment (open-pit, mobile fleet, seasonal constraints) is fundamentally different.

Last updated: 2026-04-16 (appendix preparation — no content changes, audit trail preserved as constructed)


How to Read This File

Initiative cards define the value formula and cost structure for each of Tilden's 53 initiatives. They are grouped by parent site project (TLD-P01..P16).

Three card types: - Type A — Anchored: Formula defined, key variables have workshop-confirmed values. Math can be partially computed now. - Type B — Structured: Formula defined, but most variables need corporate data to populate. The math is built, the inputs are TBD. - Type C — Absorbed: No standalone formula. Value captured in parent project (enabler, seed, or subsumed scope).

Project roll-ups aggregate initiative cards into site project totals.

Corporate Inquiry Table (end of file) collects all needs-corporate variables into one table for IE to take to Cleveland-Cliffs.
