Methods are based on creation on artifical luminescent-emissive screens on primary not luminiscent minerals by their special processing. Thus under action of radiation of lamp and especially laser source radiation, the brigth specific luminiscence arise on the native gold(fineness more than 500), native silver, and also in Ag-bearing sulfide concentrates.

The technique allows to find out the thin-occuring native gold, primary Ag-minerals in lums of ore, core samples, crushed samples, and technical products.

The methods are used:

• when prospecting for gold, silver, polymetals for field semi-quantitive express train-analysis;
• when special mineralogical mapping;
• when core working sampling for purposes of outlining of ore zones, columns, and intervals;
• when defining primary sources of placer gold;
• when adjusting scheme of sampling and ore treatment;

Advantages:

• Relative quickness of the method (up to 100 samples per instrument-shift);
• Prompt service (the method can be carried out in field conditions, that promises to correct lines of prospecting and exploration works);
• Simple maintenance;
• Low cost of works, materials and equipment.

Forms co-operation:

• Adaptation to specific ores and objects;
• Analysis of Customer’s samples and materials;
• Training of the Customer’s employers.
