Companiganj is one of the resourceful upazila of Sylhet district, though no gas or oil field have not been found yet, renowned for its hard rock. Hard rock, one of the main geo-resources of Bangladesh after gas and coal, is very useful in construction sector and cement industry. The source of this rock is near Meghalaya of India. This part of India is relatively in higher than the ground level of Bangladesh. That’s why the rock comes down by gravity especially in the rainy season. The water is the main transportation media which brings these rocks. People normally use manual hand tools for rock extraction and use two type of crusher to crush these rocks. In this research paper, we tried to find the economic feasibility of extracting these rocks. Though the extraction method of this quarry is not technologically advanced, but after doing this research, we can say that this quarry is economically feasible.
