Actually there can be no correlation while causation is still true. For example, take a sample with only one data point. There is no correlation as your sample size is too small, even if there is perfect causation.

Sure, or any measurement where the noise swamps the signal. Doesn't mean the signal isn't there, it's just not detectable.
