Sample preparation

1. Provide at least 200kg representative ore sample. It requires even more than 500kg samples for rock gold ore according to the gold particle size distribution and homogeneity.

2. If there are multiple mineral veins (or mineral zones or occurrences), take samples separately for different ore occurrences with at least 50-100kg per ore occurrence.

3. Pick the rock-mineral determination specimen. If the samples have been processed, pick the rock-mineral determination specimen separately with at least 20 pieces.

4. Channeling sampling is the most common way. Pls pay attention to the channeling spacing and distribution points.

5. Separately collect the ore samples with different properties, and do not mix them. e.g. separately collect the samples of oxidized ore and primary ore.

6. Collect both of the high grade and low grade ore sample, but not collect only the high grade type.

Document preparation

1. Provide the detailed sampling instruction which clearly inllustrates the information like sample number, weight, and so on.

2. Provide the key ore matching proportion, ore matching grade, etc.

3. Provide the detailed geological survey report of the mine or detailed document about the ore occurrence, including the deposit amount, daily mining capacity, ore grade, ore property, etc.

4. The time requirement for the experimental research.

5. The already existing research documents.
