Is there the same reward for one who is unable to go to the Sacred House of Allah and circumambulates mountains as there is for circumambulating the Kaaba?

The aforementioned hadith (definition) regarding the virtue of circumambulating the Sacred House (Kaaba) is authentic, and circumambulation is an act of worship specific to it, which cannot be performed elsewhere. Whoever circumambulates anything other than the Sacred House incurs a burden of sin unless he repents. As for "freeing a slave," it refers to the immense reward for performing the deeds mentioned in the hadiths, such as the reward for freeing a slave. Islamic law has encouraged the freeing of slaves and has assigned a great reward for it. Whoever frees a Muslim slave, Allah will free every limb of his from the Fire for every limb of the slave.
