Specification for Uranium Ore Sampling
1 Scope
This standard specifies the objectives, principles, methods, and requirements for sample preparation and transportation for non-in-situ leaching uranium ore geological sampling, including rock and mineral specimen collection, rock and mineral identification sampling, analytical sampling, isotope geological sampling, ore processing technology test sampling, and mining technology sampling.
This standard applies to geological sampling work for non-in-situ leaching uranium deposits.

3 Sampling for Rock/Mineral Specimens and Identification
3.1 Sampling Objectives
3.1.1 Rock and Mineral Specimens
Various rock and mineral specimens are collected for visual observation, comparison, and display purposes, facilitating unified understanding and standardized nomenclature of rocks and minerals.
3.1.2 Samples for Rock and Mineral Identification
The objectives of sampling for rock and mineral identification are as follows:
a)To identify and measure the content and grain size of various minerals in rocks, determine mineral physical properties and some optical parameters, study the texture, structure, mineral composition, and paragenetic associations of rocks and minerals, investigate alteration and metamorphism phenomena in rocks and minerals, and establish the nomenclature of rocks and minerals;
b) To cooperate with phase analysis and chemical analysis to determine the degree of ore oxidation, classify ore types, and study alteration zoning of deposits;
c) To determine and study the metamorphic grade of geological bodies, classify metamorphic facies zones, and assist in identifying relevant structural zones;
d) To cooperate with ore processing technology tests, providing rock and mineral identification data related to ore processing technology and comprehensive utilization of mineral resources.
3.1.3 Single Mineral Samples
Used for mineral identification, spectral analysis, chemical analysis, X-ray diffraction analysis, differential thermal analysis, and other analyses and identifications; to compare and divide metallogenic epochs (or generations); to study the occurrence state and distribution patterns of industrially significant associated, rare, and dispersed elements; to determine mineral names; and to investigate their relationship with uranium mineralization and their industrial utilization potential.
3.1.4 Paleontological Fossil Samples
Used for stratigraphic correlation and determination of geological age and sedimentary environment.
3.1.5 Artificial Heavy Mineral Concentrate Samples
Used to study the assemblage, characteristics, and provenance of accessory minerals in rocks, thereby exploring rock genesis; to study the occurrence state of useful elements in rocks (ores), ore potential, mineral assemblage characteristics, and rock geochemical characteristics; to investigate the formation and alteration of intrusive rock bodies, the provenance and transport of sedimentary rocks, and the progressive and retrogressive metamorphism of metamorphic rocks; and to obtain relevant single minerals from rocks (ores) for various analyses and tests, including isotope geological age determination.
3.2 Sampling Principles
The sampling principles are as follows:
a)The objectives for collecting specimens and samples shall be clear, with key points emphasized and representativeness ensured;
b) Sampling shall be conducted systematically according to the variations of the geological body;
c) Sampling should be carried out along the direction of greatest variation in rock layers and lithology (generally the dip direction);
d) Ore specimens shall be sampled based on ore type, mineral assemblage, texture, structure, wall rock alteration or metamorphic grade, the relationship between ore and wall rock, and the interrelationships among various minerals;
e) Unless required for special purposes, the collected specimens and samples shall be fresh samples. Field descriptions, identifications, and gamma exposure rate measurements shall be performed;
f) When collecting various types of rock and mineral specimens and samples, small specimens for preparing polished sections and thin sections shall generally also be collected, and the sectioning position shall be marked. When specially required, oriented polished section and thin section specimens shall also be collected, and gamma exposure rate measurements shall be performed;
g) Sampling should be coordinated or a single sample used for multiple purposes to allow for mutual verification and supplementation, avoiding contradictions;
h) When collecting coordinated samples or multiple types of samples, sampling should, as far as possible, be conducted at the same location, with unified processing, for use in various analyses and identifications.
3.3 Sampling Classification
The classification of rock/mineral specimens and identification samples is shown in Table 1.
Table 1 Classification of Rock/Mineral Specimens and Identification Samples
3.4 Sampling Methods and Requirements
3.4.1 Sampling for Rock/Mineral Specimens and Identification
In the early stage of geological work, a set of specimens shall be collected and gradually supplemented and improved as the work progresses. During the exploration stage, a systematic set of specimens representative of the deposit shall be collected. When arranged according to their original spatial positions, these specimens should reflect a microcosm of the deposit (ore body).
a) Sampling of Sedimentary and Extrusive Rocks: Samples shall be collected systematically according to the stratigraphic sequence, representing different horizons, rhythmic layers, and lithofacies variations.
b) Sampling of Intrusive Rocks: In addition to collecting rock specimens for each unit or intrusion along the route profile, generally at least three thin-section samples shall be taken
