Despite the small area of the Philippines, it is one of the most richly endowed nations in the world in terms of mineral resources (PSA, 2016b). Estimated production value of metallic minerals by the Philippines for the year 2014 amounted to PhP142.11B, with Gold, Copper and Nickel as the top metal ore commodities. The production value, however, went down by 22.45% to PhP110.21B in 2015 due to fluctuating market conditions (DENR, 2016).

Out of the 46 operating metallic mines of the country in 2014, 28 were in the mountain belts of Min- danao with 20 Nickel Mines, 4 Gold mines, 2 Copper Mines, 1 Chromite Mine and 1 Iron mine (Billedo, 2014). But even with 60.8% of the oper- ating mines already located in Mindanao, it is still largely untapped for its mineral wealth, estimated to host 50% of the Gold and 65% of Nickel reserves of the country (Billedo, 2014).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
