I agree with SaltySalt. It's common, and if it's on the front right, it will be crank position sensor. If it's on the front left, it will be harmonic balancer/crank shaft seal.
actually option 1 is very easy and super DIY, the motor mount oil is a thicker black, and if you pop the hood, youll see it spread all over the crash bar next to the mount

Clean the engine well and then look for the leak. Many people (including Mini Techs) have changed the oil pan gasket trying to resolve an oil leak when the leak was actually coming from the crank position sensor.
Check the oil filter housing and cooler. Sometimes leaks from the oil cooler attached to the filter housing can appear to be more like oil than coolant by the time it reaches the garage floor.
