Type a ticker. The filings become a worksheet you can challenge: every filed figure cited, every assumption yours. Review the sources, change your assumption, and compare scenarios in this research tool.
For gold and silver investors who value producers and developers themselves. Your first company needs no signup.
The Canadian exchanges list more mining companies than any other market, and most of them reach you through news releases, promotional newsletters and social media. Little of it separates what a company has reported from what it hopes for. A first look should start from the filings: what was disclosed, on which page, and what a valuation built on it shows. Enter a name you've come across, and decide from the facts whether it deserves deeper work.
Illustrative reading exercise: compare the example figures with an assumption. These checks are not automatic alerts or worksheet updates.
Use the cited figures to decide which assumption you want to review.
Review the filings, test your assumption, and return to your saved worksheet when you want to revisit your research.
Decide whether a company deserves deeper research. Stage, principal asset, resource basis, cash, burn and capital structure — each with its source and date.
Turn the technical and financial disclosure into your own economic view. Replace management's assumptions with yours; run bear, base and bull.
Reopen your worksheet to review its sources and test a different assumption.
Evaluate holdings and watchlist candidates on the same gold deck, discount rate and date.
How costs, capital and share count stand between the gold price and the share price, then the same steps on a real company. Free, no signup.
Open the filings as a cited worksheet. Change an assumption and see the case recompute.
Market assumptions and company-specific operating assumptions sit side by side. Replace any reported figure with your own; the range recalculates and the reason stays attached.

Question you asked: “If production falls 10%, gold falls to $2,100/oz and AISC rises $150/oz, what happens?” → base value/share C$2.04 · bear case falls below the share price

| $1,900 | $202.7M | $186.3M | $171.8M |
| $2,100 | $318.1M | $292.4M | $269.6M |

| $2,700 | $664.3M | $610.5M | $562.9M |
Fifteen cells the engine computed, not a curve drawn between two of them. Your case sits at $2,300 /oz and 10% — C$398.4M.
Ranges, not a target. The grid above sweeps price and discount rate only; the bull case is its $2,700 row, while the bear case moves production 10% below the filing plan, moves price to $2,100 and adds $150/oz of cost — which is why it lands below the grid's own $2,100 row rather than on it.
Holdings ask “is this still investable?” Watchlist asks “has this become investable?” Statuses are research states you set — never buy or sell signals.
Every number on a worksheet is either quoted from a filing, with its page, or labelled as an assumption you can change. Pick a figure.
Total cash costs were $1,096 per ounce sold for the quarter, compared with $1,012 in the comparative period. All-in sustaining costs were $1,410 per ounce sold, reflecting higher sustaining capital at the mill and the timing of the tailings lift. Management expects sustaining capital to normalize in the fourth quarter.

A miner's value depends on its margin: the gold price minus the cost of each ounce, less the capital it spends and the shares it issues. That can make it more sensitive to gold in both directions, and exposed to things the metal is not.
Yes. The guided path explains mining terms, why an input matters, how reported facts differ from targets and assumptions, and which questions apply to the company's stage. You get the same source-cited evidence and calculations as an experienced investor, not a simplified score or a stock pick.
No. The model reads across the filings, connects the evidence and explains what changed. The case you build on top, the conditions you set and your conclusion stay yours.
You get an explorer worksheet: geological and mineral-inventory evidence, project enablers, treasury, runway, and the financing and dilution cases you define. No mine DCF is manufactured when the disclosures cannot support one.
Every worksheet is built by reading the company's filings page by page, pulled from SEDAR+ and EDGAR, with a model whose cost scales with the pages it reads, plus the price and FX feeds that keep it current. A cheaper plan would have to read less: skip the technical report, or extract only the summary tables. That is exactly where the figure on page 38 gets missed. The price buys the whole document set, read every time, and the market data behind every recompute. Free covers two companies a month at the same depth, so you can judge the depth before you pay for the breadth.
