Clause 3. Information and data on geological and mineral samples shall be established according to Form No. 01 of Appendix II issued together with this Circular.
Article 9. Specifications for Geological Samples and Mineral Samples
1. Block Samples
a) Block samples are used to observe and describe petrographic or mineralization characteristics. The samples have a rectangular or cubic shape, arranged according to stratigraphic sequence or depth. The size is (3×6×9) cm and must be fully described with all petrographic and mineralization characteristics as specified by technical regulations.
b) Block samples used for analysis (thin sections, petrography, isotopic) must have dimensions ranging from (5×3×2) cm to (9×6×3) cm in length, width, and thickness. For petrographic samples with directional structure, the orientation and dip must be clearly determined before sampling. Collected samples must be fresh, solid, and meet analytical requirements.
c) Block samples for mechanical and physical property analysis and small density determination are taken with dimensions ranging from (10×10×10) cm to (30×30×30) cm in length, width, and thickness. After collection, the samples must be sealed tightly with wax or paraffin to maintain their natural state and initial moisture.
d) Block samples for physical parameter analysis (geophysical parameter samples) must be collected and preserved in their original intact state, maintaining their initial natural condition. After collection, the samples must be wrapped in cloth, wax, paraffin, or suitable preservation tools to minimize changes in physical state and natural characteristics.
đ) Density measurement samples: maximum dimensions (10×10×10) cm in length, width, and thickness.
e) Magnetic parameter samples: maximum dimensions (20×10×5) cm in length, width, and thickness; to determine residual magnetic vector Jn and paleomagnetic direction, cube or rectangular block samples with edge lengths from 5.0 cm to 20 cm should be taken, with the north direction and two square edges' azimuths of the sample determined.
g) Electrical parameter samples: at least one relatively flat surface, minimum dimensions (10×10×10) cm.
h) Radioactive parameter samples: minimum dimensions (7×7×7) cm.
i) Radioactive chemical samples (to determine emanation coefficient, radioactive equilibrium) are taken in their original form, with dimensions (10×10×10) cm.
k) Block samples for paleontological research must be taken with sufficient size to identify the maximum morphological and structural features of fossils. At the end of the project, block samples must be reduced according to current regulations on geological sample management and reduction. For paleontological samples, only characteristic and scientifically valuable samples are retained.
2. Slot Samples
a) Slot samples are arranged perpendicular to the ore body to ensure the highest representation of actual component and thickness of the ore body. Depending on actual conditions such as topography, attitude (dip angle, strike), and ore uniformity, slot samples may be taken vertically or horizontally. Subsequently, measurement results will be converted to true thickness for resource and reserve calculations.
b) Slot sample dimensions are defined as follows: width from 5.0 cm to 10 cm, depth from 3.0 cm to 5.0 cm. Sample length depends on the type of ore and ore body uniformity to determine.
3. Point Samples, Slot Point Samples, Grid Point Samples
a) Point samples are used in primary rock geochemical sampling, in the discovery of mineralization through rolling stones, or to check for potential mineralization in large outcrops with unclear mineralization. Point samples must be uniform.
b) Slot point samples are used in investigations and evaluations of easily identifiable minerals by eye, with characteristics of component variation following a certain pattern (stratification, layering, banding, or striping) such as construction materials, cement limestone, phosphorite, and other minerals. Slot point samples consist of blocks collected along one or several lines perpendicular or nearly perpendicular to the ore body's direction.
c) Grid point samples are used for minerals distributed in clusters, leopard skin patterns, or irregularly without clear patterns. Samples are taken in small blocks distributed in rectangular, square, triangular, or diamond grids. Each block has a size of about 1.0 cm to 3.0 cm, taken at grid points. The distance between grid points depends on the uniformity and size of ore clusters or outcrops.
4. Stripping Layer Samples
a) Stripping layer samples are used in investigating types of minerals with uneven distribution in two directions: thickness and strike or thickness and trend.
b) Stripping layer samples are taken in the shape of one side being the thickness of the ore body and another side following the change direction of the ore body in mining works.
c) The sampling area must be flat, and the sampling depth must be uniform to ensure the representativeness of the sample.
5. Block Samples
a) Block samples are taken directly at sites after cleaning the surface of outcrops, pits, trenches, or wells. Block samples are used to determine parameters such as bulk density, recovery rate, and other mechanical properties as required by research.
b) Block samples taken for research purposes must be returned to the site, ensuring that the sampling location is cleaned and restored appropriately. The retained sample portion only includes the necessary volume for analysis and quality determination as required.
6. Drilling Core Samples
a) Drilling core samples are arranged on trays with dimensions (0.3-0.5)m x 1m, divided into 3-5 sample compartments. Samples are arranged in increasing order of depth. On each tray, an etiket must be attached with detailed information about the drilling interval, accompanied by an arrow indicating the depth direction. The start of each tray must clearly indicate the drill hole name and depth range (- to). The observer is responsible for describing and marking rock layers on the sample tray according to technical regulations. Photographs of the sample tray must clearly show the date of photography, tray sequence, stratigraphic depth, drilling interval parameters, and sample depth range in each tray.
b) When the project plan and report have been approved by the competent authority, sample retention should be reduced, retaining only the ore samples and a representative number of samples. For reports using non-budgetary funds, the decision on whether to retain or reduce core drill samples shall be made by the investor who will bear responsibility for retention except in cases of mineral exploration.
Article 10. Catalogue of Museum Samples
1. The catalogue of museum samples includes: rock samples, mineral specimens in lump form, single mineral samples, paleontological samples, fossil samples, rock samples in mineral form, crystal samples; semi-precious stone samples, decorative stone samples, stone veneer samples, core drill samples.
2. Annually, geological and mineral samples submitted by organizations and individuals pursuant to Clause 1 of Article 8 of this Circular, the agency responsible for storing geological and mineral information and data shall review, select, and propose a catalogue and quantity of museum samples for approval by the competent state management agency.
3. Museum samples shall be preserved according to the provisions of Clause 2 of Article 8 of this Circular and relevant technical regulations.
4. The agency responsible for storing information and data on museum samples shall establish digital data for museum samples, including: detailed descriptions, illustrative images, 3D models, source of collection, and classification based on professional criteria.
5. Annually, the agency responsible for storing geological and mineral information and data shall conduct reviews and evaluations of the current status of samples; compile and develop plans for collecting and supplementing samples to complete sets of museum samples, ensuring systematic representation and serving display, research, and educational purposes.
6. Information and data forms for museum samples shall be established according to Form No. 02 attached as Appendix II to this Circular.
