Lab Result
Chemical Composition
| Element | Symbol | Unit | Value (approx.) |
|---|---|---|---|
| Zinc | Zn | % | 52.5 |
Other notes
-
Strontium determination (FT-IR) reported as “Low”, no significant strontium contamination.
-
No other major metals are quantified in this report.
Economic Values
Main economic metal
-
A Zn grade of 52.5% is in the range of high-grade zinc ore or zinc concentrate, well above typical run-of-mine ore.
At this grade, the material is mainly valued for its zinc content; by-product credits are not evaluated in this report. -
The absence of major impurity metals or penalty elements in the certificate is positive, but buyers would normally request a full multi-element assay for commercial negotiations.
Market & Application
-
Material at ~52.5% Zn is suitable as smelter feed or concentrate blend in zinc smelting and refining operations.
-
This analysis demonstrates that our zinc material can be upgraded or selectively sourced to reach higher Zn grades when required.
-
For long-term contracts, this test will typically be combined with mine-head and bulk-cargo assays to define a specification range (e.g., standard ore at ~38–42% Zn, premium lots higher).

Laboratory Information
Regional analytical laboratory (Iran)
Laboratory: Regional analytical laboratory (Iran)
Sample reference: zno% 21091402
Material: Zinc ore from our Afghan operation
Context: Mine-head / site sample composed of multiple subsamples
Number of highlighted subsamples: 2 (representative of typical ore quality)
Reported elements: Mg, Ni, Cd, Co, Mn, Cu, Fe, Ag, ZnO, Zn, PbO
Summary
The aim of this test is to define the chemical signature and typical grade range at the mine. This analysis represents mine-level zinc ore (code: zno% 21091402) tested by a regional laboratory. Two highlighted subsamples show zinc grades from ~32.6% to 40.6% Zn, with low lead oxide (PbO 0.22–0.25%) and moderate iron and copper.
Lab Result
Chemical Composition
| Element | Symbol | Unit | Value (approx.) |
|---|---|---|---|
| Magnesium | Mg | % | 0.413–0.475 |
| Nickel | Ni | ppm | 79.5–152 |
| Cadmium | Cd | ppm | 136–182 |
| Cobalt | Co | ppm | 31–53 |
| Manganese | Mn | % | 0.357–0.368 |
| Copper | Cu | ppm | 43–85 |
| Iron | Fe | % | 5.05–6.27 |
| Silver | Ag | ppm | <10 |
| Zinc Oxide | ZnO | % | 30.76 39.24 |
| Zinc | Zn | % | 32.56–40.62 |
| Lead Oxide | PbO | % | 0.22–0.25 |
Other notes
-
These values show a medium- to high-grade zinc ore with modest impurities.
Economic Values
Main economic metal
-
Main value: Zinc, with Zn 32.6–40.6%, which is attractive as zinc ore / pre-concentrate feed.
Lead: PbO 0.22–0.25% (corresponding to very low Pb) – not enough for a separate lead credit but beneficial because it avoids strong lead penalties. -
Impurities:
Fe at 5–6% is typical for zinc ores and manageable in most smelter flowsheets.
Cd at 136–182 ppm should be monitored; many smelters apply Cd thresholds, but these levels are usually manageable. -
Other metals (Ni, Co, Cu, Mn) remain in trace to low ranges and act mainly as gangue.
-
Overall, this analysis suggests a solid commercial zinc ore with a clean impurity profile.
Market & Application
-
Ore with ~33–41% Zn is suitable for zinc smelters and traders as either direct ore feed or blending material.
-
The low PbO and limited impurities make the ore attractive where smelters are concerned about environmental and metallurgical penalties.
-
This data is typically used to define the “typical ore spec” for long-term supply, while SGS cargo assays (see next analysis) confirm export cargo quality.

Economic Values
Main economic metal
-
Zinc (~41.26%)
Falls in the range of commercial zinc ore suitable for smelters and traders.
At this grade, zinc is the primary value driver in the cargo. -
Lead (~6.40%)
Provides a secondary value component as lead metal.
Depending on smelter and contract, Pb may be paid as a separate credit or factored into overall value. -
Overall
The combination of ~41% Zn and ~6% Pb classifies the cargo as a Zn–Pb ore. -
Actual payables will depend on agreed treatment/refining charges, deduction schedules, moisture, and any impurity limits defined in the final contract (impurities are not listed on this page).
Market & Application
-
This cargo is suitable for zinc–lead smelters or integrated plants that can recover both metals from mixed ore feed.
-
An SGS report is widely recognised in the industry and provides strong third-party assurance on grade and sampling procedure.
-
For buyers, this document confirms that large-scale cargo from the stockpiles can reliably deliver around 41% Zn and 6.4% Pb on a dry basis.
-
This SGS result is ideal to:
-
Support initial negotiations and LOIs
-
Demonstrate that our zinc ore can reach export-grade specifications at bulk ports
-
Serve as a basis for defining contract specifications, with future cargos referenced to this grade.
