Proved Ore Reserve Calculator
Summarize explicitly already independently classified proved dry-tonnage inventory, unknown labels remain separate; no geological/economic classification, reserve declaration or confidence inferred. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
A proved inventory subtotal summarizes a classification established before this calculation.
A proved inventory subtotal summarizes a classification established before this calculation.1
This tool counts exact labels without assigning geological or economic confidence.
When to use Proved Ore Reserve Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Proved Ore Reserve Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedAlreadyClassifiedTonnes, callerIndependentClassLabels, using the field meanings and rules below, then run the tool.
- Read matchedTotal, matchedCount, unclassifiedCount. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAlreadyClassifiedTonnes | Observed already classified tonnes | list of number | Required |
| callerIndependentClassLabels | Caller independent class labels | list of string | Required |
Use aligned nonnegative tonnes and nonblank class labels. Match the exact proved token for total and count, and count literal unknown separately. Other nonblank labels are accepted but contribute neither to the target nor unknown count; duplicate records are not detected because this tool has no ID field.
matchedTotal=Σ_labelEqualsTarget tonnes; matchedCount=count(label=target); unclassifiedCount=count(label=unknown) Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| matchedTotal | Matched total | number |
| matchedCount | Matched count | number |
| unclassifiedCount | Unclassified count | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
Alternative or Complementary methods
For a related step, use Total Ore Reserve Calculator: A reserve inventory summary needs nonduplicate blocks with classifications already assigned independently. For a complementary comparison, use Probable Ore Reserve Calculator: A probable inventory subtotal summarizes a classification established before this calculation.
