Geosoc together with other geology students went to Padcal, Benguet to visit the mining area of the Philex mining corporation last April 2-3, 2011. This activity aims to broaden the knowledge of the geology students in the field of mining, to give them a background of the mining industry, and to expose them to what they will be doing in the future if they choose to pursue mining.
After the museum, we went to the “core log house” which stores hundreds or even thousands of core logs that were drilled recently or even years ago. These served as references to where the mining should take place. This core logging, highlights the main role of the geologists in the mining industry. They are responsible for the directions of the drilling. They will identify the rocks present in the core and then they will know the orientation or position of the minable materials such as gold through association. It may sound simple but the task should be carried out with utmost care and thinking because each drilling costs a lot of money.
Next to the “core log house” was the assay laboratory. The team demonstrated to us the preparations they do for the analysis of the samples and for knowing the percentage composition of each sample. There, we observed under a microscope a flake of gold embedded in a rock.
After the laboratory, we proceeded to the briefing and distribution of the equipments for our trip underground. Everyone was excited to descend underground with the complete outfit and gears. The whole trip was tiring but fun and full of experience. We were able to see the actualities of mining especially the part on exploration. We were also able to observe the organization inside the mine – the different roles the people play in order to carry out the mining process. For example, the role of mining engineers, mechanical engineers, geologists, etc. It was just amazing to think that we were actually in the core of the mountain thousands of meters from the surface. And with us were huge tanks and bulldozers very busy on their respective tasks.
Next was the “mill operations”. This is where the processing of the ores gathered from the mining production lines take place. The end products here are the extracted important metals from the ore ready for export or transport for further processing. The process involves big machineries. The process seemed to be complicated but according to the metallurgical engineer that toured us, “It is just as simple Chem16.”
