1. What is the primary purpose of mineral resource classification
systems?
A. To estimate mining equipment costs
B. To categorize resources based on geological confidence and
economic feasibility
C. To determine shipping routes for minerals
D. To regulate labor wages in mining operations
Answer: B
Rationale: Mineral classification systems organize resources based
on certainty and economic viability, aiding exploration and
development decisions.
,2. Which mineral is most commonly used as the primary ore of iron?
A. Galena
B. Hematite
C. Bauxite
D. Chalcopyrite
Answer: B
Rationale: Hematite is one of the most abundant and economically
important iron ores.
3. What does "ore grade" refer to?
A. The depth of a mineral deposit
B. The weight of ore transported
C. The concentration of valuable mineral in rock
D. The hardness of a mineral
Answer: C
Rationale: Ore grade measures the percentage of valuable mineral
content in a deposit.
4. Which geological process forms placer deposits?
A. Volcanic eruption
B. Chemical precipitation
C. Sediment concentration by water or wind
D. Metamorphism
Answer: C
, Rationale: Placer deposits form when heavy minerals are
concentrated by flowing water or wind.
5. Which mineral property is most useful for field identification?
A. Radioactivity
B. Color alone
C. Hardness
D. Magnetic susceptibility only
Answer: C
Rationale: Hardness is a consistent diagnostic property used in
mineral identification.

7. Which of the following is a metamorphic rock?
A. Basalt
B. Sandstone
C. Marble
D. Obsidian
, Answer: C
Rationale: Marble forms from metamorphism of limestone.
8. What is the main purpose of geochemical sampling?
A. To map political boundaries
B. To determine mineral composition of soils and rocks
C. To measure atmospheric pressure
D. To test water pH only
Answer: B
Rationale: Geochemical sampling identifies elemental composition to
detect mineralization.
9. Which mineral is commonly associated with copper deposits?
A. Quartz
B. Chalcopyrite
C. Gypsum
D. Halite
Answer: B
Rationale: Chalcopyrite is a major copper-bearing mineral.
10. What does "stripping ratio" refer to in mining?
A. Ratio of ore to water used
