How does the skill extract AISC (All-In Sustaining Cost)?

The skill uses a priority-based approach: first searching SEC XBRL filings for standardized fields, then parsing MD&A text for keywords, and finally using a proxy formula (OpCost + SustCapex + G&A - Byproduct) / Oz if direct disclosure is missing.

What is the purpose of the 'Backsolve' logic?

Backsolve logic allows you to set a target ratio (e.g., a historical peak of 1.7) and mathematically determine what specific improvements in AISC, debt reduction, or multiple expansion would be required to reach that level.

Which metals and mining universes are supported?

It supports any metal symbol available via Yahoo Finance (e.g., SI=F for Silver, GC=F for Gold) and can analyze individual stocks or entire ETF holdings like SIL, GDX, or SILJ.

Can this skill generate visual reports?

Yes, it includes scripts to generate a four-panel visual dashboard containing time-series ratios, factor radar charts, fundamental scoring bars, and scenario-based heatmaps.

Decomposes mining stock-to-metal price ratios into fundamental drivers like AISC, leverage, and valuation multiples using automated financial data extraction.

关于

This skill provides a quantitative framework for analyzing the valuation gap between mining companies and their underlying physical metals. By automatically scraping financial reports from SEC EDGAR and SEDAR+, it extracts key metrics—All-In Sustaining Costs (AISC), net debt, EV/EBITDA multiples, and share dilution—to perform a four-factor decomposition of the 'Miner/Metal Ratio.' It is particularly useful for macro analysts and investors seeking to determine if a mining stock's underperformance is due to fundamental cost pressures, leverage issues, or broader market sentiment, providing actionable 'backsolve' targets for recovery scenarios.
