A Strategic Mineral
High-Grade Antimony Feed
Antimony is a strategically important metal used across flame-retardant systems, lead-alloy hardening, specialty chemicals, ammunition, semiconductors and a growing range of energy and defence applications.
Antimony-bearing ores are commonly associated with stibnite and other mineral phases. Commercial performance, however, is determined by more than Sb grade alone. Mineralogy, sulfur, arsenic, lead, silica, iron, liberation characteristics and particle size can all influence the appropriate processing and smelting route.
Laboratory-tested samples demonstrating a broad range of high antimony values.
Very low lead reported in selected material, including Pb below 0.02% in one Qualitest assay.
Independent analytical results obtained using titrimetric, ICP-AES and ED-XRF methods.
Scope for buyer-specific sampling, metallurgical evaluation, beneficiation and lot qualification.

Chemical Composition
| Element | Symbol | Unit | Reported value |
|---|---|---|---|
| Antimony | Sb | % | 38.10% |
Key Characteristics
- SGS reports 38.10% Sb in the submitted antimony sample.
- The result was determined by an acid-digestion titrimetric method specifically targeting antimony content.
- This sample represents the lower end of the published King Mining antimony assay portfolio and provides a useful reference for medium-to-high-grade ore evaluation.
- The SGS report measures Sb only; a complete impurity profile was not included in this test.
Potential Technical Review
- Complete a multi-element assay covering As, Pb, Fe, Si, S and other buyer-specified elements.
- Determine mineral phases and liberation characteristics.
- Evaluate direct processing, beneficiation or blending options according to the buyer's plant and target feed grade.
- Confirm commercial-lot composition through agreed representative sampling.

| Zinc | Zn | % | 0.036% |
Key Characteristics
- CRL reports 76.430% Sb, the highest reported antimony value among the samples currently published by King Mining.
- Sulfur is the principal associated element reported by the XRF analysis.
- Iron, copper, manganese and zinc are present at comparatively low reported levels.
- The test provides an elemental XRF profile rather than a complete mineralogical characterization.
Potential Technical Review
- Confirm Sb concentration using an additional quantitative wet-chemistry or ICP method before establishing a commercial specification.
- Identify the Sb-bearing mineral phases through mineralogical analysis.
- Determine sulfur deportment and the relationship between Sb and sulfide minerals.
- Conduct representative multi-sample testing before extrapolating the result to a larger ore lot.

- The multi-element analysis provides considerably more information about associated elements than Sb-only assays.
- Lead is reported at 0.055%, while zinc and several other measured metals are below the stated detection threshold.
- Arsenic is reported at 0.33% and should be evaluated against the receiving smelter's individual acceptance and penalty schedule.
Potential Technical Review
- Compare the reported arsenic level against the buyer's maximum feed specification.
- Confirm antimony and key penalty elements through buyer-selected or mutually agreed assay procedures.
- Determine whether arsenic is locked within the antimony mineral phase or associated with separate minerals.
- Develop processing, sorting or blending options where required by the receiving facility.
