Students conducted underground fieldwork at the Itogon-Suyoc Resources Inc. tunnel.
The students visited the Itogon-Suyoc Resources Inc. (ISRI) in Itogon, Benguet. Itogon-Suyoc Resources Inc. (ISRI) is a subsidiary of Apex Mining Company Inc. (AMCI). The trip was made possible through Dr. Eric S. Andal, Vice-President of Geology and Exploration of AMCI. Underground fieldwork was conducted to look at the mineralization of the vein system, particularly the Taka Barr vein which is the most productive and has the highest gold grade. The students were also able to look at the exploration drill core samples. Geologists from ISRI, namely Ms. Danella Trina Callosa, Mr. Paul Villora, Mr. Eldy Lim, Ms. Angela Joyce Tamaño, Mr. Ray Mark Gaviño led the team and the discussion on the structural controls of the deposit.

The 2nd leg of the fieldwork was at LNL Archipelago Minerals Inc. in Sta. Cruz, Zambales. The fieldwork was made possible through Engr. John Gregory M. Go, General Manager of LNL. The students visited chromite and nickel laterite outcrops, and mantle outcrop exposures of the Zambales Ophiolite Complex, which hosts the chromite and laterite deposits. Dr. Gabo-Ratio highlighted the processes involved in the formation of magmatic and weathering deposits. The class also visited LNL’s nursery and rehabilitation area and had the opportunity to conduct tree-planting activities. Ms. Arianne Destura, a Mine Geology Officer assisted the team at the mine site.
