Explanation

To determine which statement is true regarding ores and minerals, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Minerals and Ores**:
- **Minerals**: Naturally occurring inorganic substances with a definite chemical composition and crystalline structure.
- **Ores**: Specific types of minerals from which metals can be extracted profitably.

2. **Analyzing Option 1**:
- Statement: "All ores are minerals but all minerals are not ores."
- This statement is true because all ores are indeed minerals, but not all minerals can be classified as ores since some may contain impurities or may not be economically viable for metal extraction.

3. **Analyzing Option 2**:
- Statement: "All minerals are ores but all ores are not minerals."
- This statement is false because while all ores are minerals, not all minerals can be classified as ores.

4. **Analyzing Option 3**:
- Statement: "Both the above statements are wrong."
- This statement is also false because option 1 is correct.

5. **Analyzing Option 4**:
- Statement: "None of these."
- This statement is false since option 1 is correct.

### Conclusion:
Based on the analysis, the correct answer is **Option 1**: "All ores are minerals but all minerals are not ores."
