What this tool covers

Supports unit conversion, price scenario comparison, sensitivity analiz, PDF export, and çok dilli use across regions.

Instant calculation

Normalize prices and maliyets, then calculate the break-even cutoff grade immediately.

Unit conversion

Convert g/t, %, ppm, oz/t, and kg/t to absorb differences in regional notation.

Scenario comparison

Compare Low / Base / High cases by changing metal price only.

Easy to paylaşım

Save the result as a PDF from the tarayıcı print diakayıt and use it in meetings right away.

How to use

  1. 1 Enter the metal price para birimi, unit, and recovery.
  2. 2 Align madencilik maliyet, processing maliyet, and G&A to the same ore basis unit.
  3. 3 Add scenario rows if needed and review the sensitivity span.
  4. 4 Check the cutoff grade and export it by CSV or PDF.

Glossary

cutoff grade
The minimum grade used as a break-even reference.
recovery
The paylaşım of metal recovered from the ore.
G&A
Short for Genel & Administrative expense.
ppm
In this tool, ppm uses the same number as g/t on a metric-tonne basis.
st / lt
Short ton and long ton. Ambiguous ton is not accepted.

Formulas

Metal price / g = metal price ÷ grams per price unit
Total maliyet / t ore = (madencilik maliyet + processing maliyet + G&A) × ore basis factor
cutoff grade (g/t) = total maliyet ÷ (metal price / g × recovery)
g/t → % = g/t ÷ 10000
g/t → oz/t = g/t ÷ 31.1034768

SSS

What is cutoff grade?

It is the minimum grade used as a break-even reference. It changes with metal price, recovery, and maliyet assumptions.

Does this tool handle payability?

Not in the first version. It assumes 100% payable and uses recovery only.

Are ppm and g/t the same?

Yes, on a metric-tonne basis this tool uses the same number for ppm and g/t. It treats 1 ppm = 1 g/t.

Can I use short ton and long ton?

Yes. Enter t, st, or lt explicitly. Ambiguous ton is not accepted.

Can I save PDF çıktı from the tarayıcı only?

Yes. The tool provides a print layout and uses the Chrome / Edge / Safari print diakayıt for PDF saving.

Notlar

  • This tool is for quick reference only and does not replace JORC / NI 43-101 / technical reports.
  • Dilution, madencilik loss, payability, royalties, taxes, and freight are not part of the core calculation.
  • Enter metal price and maliyet in the same para birimi.
  • All calculations stay inside the tarayıcı and are not sent to the sunucu.
