The sample is likely to be from a meteorite.

The reason for this is the fact that the isotope Copper-63 is more abundant on planet Earth than the isotope Copper-65 is. Therefore, if a sample of rock has Cu-65 in a greater quantity, it is likely to be from outer space. Many other elements entered the Earth's crust as a result of meteorite impacts, such as Iron (Fe).
