Know if a mining stock is worth owning — and what still needs an answer
“Have a hunch, grab a bunch” is how most investors get burned on mining stocks. CoreMultiplier replaces the hunch with a framework: it pulls the numbers straight from SEC and Canadian filings, scores the company against 44 published tests, and works out what it could be worth at a gold price you choose. Then it tells you the one thing a score can’t: what the filings still don’t say, and how to ask.

What you get
Everything a mining investor needs
Built by a mining investor, for mining investors. Not a generic screener bolted onto gold data - a purpose-built evaluation system.
44-Test Scoring Model
Every company is graded against 44 published tests across eight areas - asset quality, management, capital structure, jurisdiction, growth, cost position, balance sheet, and relative value. Every score decomposes into the tests behind it, right down to the answer and the filing it came from.
Open Questions
CoreMultiplier does not just score a company - it tells you what its own record still does not settle: a financing gap, an unexplained management decision, a resource that has not been upgraded. Get a drafted email to investor relations, sent from your own inbox.
Projected Return, At Your Price
Set a future gold and silver price once, and every company recalculates: future cash flow times your multiple for producers, or a resource-based estimate for developers with no cost basis yet. "Show Your Work" prints the arithmetic line by line.
Refreshed Every Night, Automatically
No stale spreadsheets and nothing for you to run. Every AISC, reserve figure, and share count is re-checked against the most recent filing on a nightly schedule, with market prices refreshed twice on trading days.
Jurisdiction Red Flags
A severe jurisdictional problem cannot hide inside an average score. Any company with more than 30% of its production in a country the US State Department rates "Do Not Travel" gets an unconditional red flag, independent of every other strength it has.
Stock Sentiment, Kept Separate
A great company the market is ignoring, and a mediocre one riding a hot chart, are both real things worth seeing. Nine deterministic signals - momentum, trend, news, flows - are tracked on their own axis, never blended into the company-quality score.
Core School - Built In
A structured 23-lesson curriculum teaches you to value majors, mid-tiers, developers, and explorers using the exact same methodology CoreMultiplier runs under the hood - including how to use Open Questions well.
Your Portfolio, Private
Your cost basis, share counts, and position sizes never leave your account. Company data and Open Questions answers are shared to keep them useful to everyone; your personal numbers stay yours.
New in CoreMultiplier
A score tells you what the filings say. Open Questions tells you what they don’t.
Every company carries a short, capped list of the specific things its own record raises but does not answer - the things that would genuinely change whether you buy, hold, or sell. No hallucinated numbers, no invented facts: every question quotes the exact record it came from.
CoreMultiplier is never in the send path. The email leaves your mailbox, the reply comes back to your mailbox - which is exactly why an answer you record is visible to every other holder of the company the same day.
CoreMultiplier finds what the record does not settle
Two questions come from pure arithmetic - a financing gap, an unconverted resource. The rest come from a nightly read of everything on file: the numbers, the mines, every graded test, recent news - thinking adversarially about financing, management, insiders, jurisdiction, and more. It is never allowed to use anything it was not shown, and an empty field is treated as a question, never as permission to guess.
You ask, from your own inbox
Every open question carries a drafted email to the company’s investor-relations contact, found automatically from its own website. It opens in your email program, never CoreMultiplier’s - the reply comes straight back to you.
Record the answer, and everyone benefits
Press "I got an answer" and it is shown to every CoreMultiplier user, with your name or a stable alias if you would rather not share it. A question stays open - never deleted, never silently reworded - until someone answers it or it stops applying.
A bad answer gets flagged, not filed away
If the numbers that closed a question moved against you - more dilution, less cash, weaker reserves - the question is promoted to a red "finding" that stays until you dismiss it, with the before and after shown side by side.
The workflow
From ticker to investment decision, hands-off
CoreMultiplier eliminates the hours spent digging through PDFs, reconciling numbers, and second-guessing your math. The analysis and the monitoring both run automatically.
Add a company to your portfolio
Search for any gold or silver miner by ticker or name. CoreMultiplier resolves the right listing and starts tracking it - nothing to configure.
It researches automatically, overnight
A nightly run pulls the latest SEC and Canadian regulatory filings, extracts AISC, reserves, production, share structure, management, and mines - and re-checks all of it on every future run. There is no button to click.
Review the score, the return, and the open questions
