Quantity and volume
Estimated tonnage should be assessed using geometry, density assumptions, historical records, weighing data or staged collection results. Bulk density can materially affect tonnage estimates.
Mineral Stockpiles
Above-ground mineral stockpiles require technical, physical and commercial evaluation.
Mineral stockpiles are accumulated raw material volumes stored above ground for later processing, trading, blending, collection or industrial use. Their commercial value depends on composition, quantity, homogeneity, moisture, particle size, access, collection readiness, environmental profile and buyer specification.

Sampling & Quantity Review

Technical Evaluation
How mineral stockpiles are evaluated before commercial discussion.
A mineral stockpile cannot be evaluated only by visual inspection. Technical review normally combines physical inspection, representative sampling, quantity estimation, laboratory analysis and commercial buyer specification.
Representative sampling
Samples should reflect the full stockpile, including surface, interior, base, colour variation, particle size variation and moisture differences. Single-point sampling is not enough for serious buyer review.
Commercial suitability
Buyers review whether the material fits their processing route, impurity limits, storage requirements, collection schedule, logistics and payable value structure.
Current Stockpile Reference
Initial material ready for collection and larger volume planned for staged storage.
Viden Grup currently presents an initial mineral stockpile reference of approximately 22,000 MT ready for collection, with a larger estimated trading volume of approximately 350,000 MT to be processed and stored in staged lots.

Initial quantity ready for collection and commercial buyer review.
350,000 MT
Estimated trading volume planned for processing and storage in 20,000–25,000 MT lots.
Stockpile Parameters
Key physical and commercial factors in stockpile review.
| Parameter | Technical Meaning | Commercial Impact |
|---|---|---|
| Quantity | Estimated or measured tonnage available for collection or storage. | Defines shipment size, lot structure, buyer commitment and logistics planning. |
| Homogeneity | Consistency of material composition across different zones of the stockpile. | Affects assay reliability, pricing confidence and buyer risk. |
| Moisture | Water content in the material. | Impacts net payable weight, handling, transport and storage behaviour. |
| Particle size | Fine, granular, compacted or mixed-size material distribution. | Influences dust, loading, processing, screening and buyer preparation route. |
| Access | Physical ability to collect, load and move the material. | Can reduce or increase logistics cost and collection timing. |
| Environmental profile | Potential leaching, sulphide oxidation, dust and water interaction. | May influence buyer acceptance, storage requirements and handling controls. |
Sampling Logic
Representative sampling is the bridge between visual stockpile and commercial material.
For serious commercial evaluation, buyers usually need confidence that the sample represents the whole stockpile. Sampling should consider depth, surface weathering, colour variations, grain size and moisture.
Multiple collection points
Samples should be collected from several parts of the stockpile rather than only from the surface or edge. Different zones may show different oxidation, moisture and composition.
Composite sample preparation
A composite sample can be prepared from several increments to represent the average condition of the material. Counter-samples may be retained for verification.
Laboratory analysis
Analytical review should include main payable elements, moisture and penalty elements relevant to buyer processing routes.
Buyer specification match
The material is then matched against buyer limits for composition, moisture, particle size, storage, impurity thresholds and delivery basis.
