Junior mining · due diligence tool · V10

Read a junior gold explorer the way a professional does.

A structured checklist for private investors: a 28-question quick screen with hard stops, a 199-row questionnaire that adapts to the company's stage, thirteen calculators, and a glossary. Every row says what it means, where to find the answer and which answer is good. Your entries stay in your browser; export them whenever you like.

How to use

    Legend

    Currency, price deck and calibration

    Quick screen

    28 public-source checks, 60-90 minutes

    Answer every row before reading any geology. Under the author's rule any hard stop, or three or more counted red flags, ends the analysis. Row references point to the full guidance in the questionnaire.

    Questionnaire

    199 criteria in 16 sections

    Fill Answer, Result, Source and Notes. Tier 1 = quick public-source checks; Tier 2 = core deep dive; Tier 3 = optional or expert. Score one fact in one row only. Hover or focus a chip for its meaning.

    Rows are gated to project stage . .

    This row applies from a later project stage. It is hidden by default; if you score it anyway, the result is counted.

    Calculators

    Every number-bearing rule, computed

    Example values are shown; replace them with the company's figures. Blank price fields fall back to the price deck.
