Assaying

Precious Metal Assaying & Analysis

Aussiemint provides professional assaying and precious metal analysis for clients who need clear, evidence-based value from gold and silver materials. Whether you are assessing dore, mined gold, mixed-carat jewellery, estate scrap, lemel, sweeps, bullion or manufacturing waste, accurate testing is essential before refining, settlement, buyback or bullion conversion.

Assaying gives commercial clients a clearer understanding of metal content, purity and recoverable value. For miners, it supports yield visibility. For pawn brokers and gold buyers, it helps verify scrap lots quickly. For jewellers and manufacturers, it helps identify fine metal value in trade residues and production by-products.

Where required, Aussiemint can support testing pathways using fire assay, XRF analysis, ICP-based analysis or physical authenticity checks, depending on the material type, grade and intended commercial outcome.

Analytical Methods We Can Support

Fire Assay

Fire assay is widely used for high-value gold and silver determination, especially where a more detailed result is required for dore, mined material, bullion, lemel or commercial refining lots. It is suited to clients who need stronger confidence before settlement or refining.

XRF Analysis

XRF is a fast, non-destructive screening method used to identify elemental composition. It is useful for mixed-carat jewellery, bullion checks, scrap sorting and initial verification, particularly where quick commercial decisions and rapid liquidation are required.

ICP-Based Analysis

ICP analysis may be used where broader elemental profiling or trace-level information is required. It can support investment-grade purity verification, base metal scans and high-purity precious metal assessment where suitable.

Density & Authenticity Checks

Physical testing can help support bullion and coin verification by comparing weight, dimensions and density against expected specifications. This can be useful for detecting inconsistencies before further analysis.

Assaying for Commercial Clients

Mining Operations

Aussiemint supports miners, prospectors and exploration clients with assay pathways for raw, alluvial and semi-refined gold or silver material, including dore. Testing can help clarify precious metal content, support yield reporting and guide the next step into refining, settlement or bullion conversion.

Pawn Brokers & Gold Buyers

For pawn brokers, gold buyers and second-hand dealers, rapid verification matters. Aussiemint can assist with mixed-carat jewellery, estate scrap and liquidation lots that need quick assessment before buyback, refining or bank transfer settlement.

Jewellers & Manufacturers

For jewellers and manufacturers, assay support helps identify recoverable value in lemel, filings, sweeps, bench waste, casting material and other trade by-products.
