GIA Diamonds Do Good (DDG) 2025 – 400 Free Practice Questions to Pass the Exam

The profitability of a diamond mine is primarily influenced by its ore grade. Ore grade refers to the concentration of diamonds within the mined material; a higher ore grade indicates a greater amount of diamonds can be extracted from a given volume of ore, which directly affects the potential revenue.

When the ore grade is high, the overall yield of diamonds is likely to increase, resulting in higher profits for the mine. Conversely, if the ore grade is low, the mine will produce fewer diamonds, which can significantly hurt profitability. Therefore, understanding the ore grade is crucial for evaluating the economic viability of a diamond mining operation.

Other factors listed, such as geographical location, depth, and mining technology, can impact operations and costs, but they do not have as direct an effect on profitability as ore grade. For example, a mine might be located in an advantageous geographical area, but if the ore grade is low, it may struggle to be profitable despite its location. Conversely, advanced mining technology can enhance efficiency but ultimately hinges on the underlying ore grade for profitability.
