The application of life cycle assessment in mining industry is still limited, especially small-scale mining. According to the mining sites due diligence, small-scale mining practices in the Philippines are mostly unregulated, so there is a lack of data, especially inventory data. The objectives of this research is therefore to build a local life cycle inventory data for the small-scale gold production in the Philippines and estimate its life cycle impacts using LCA method. The result shows that the factor driving the gold production system is the ore characteristic. The level and amount of contamination to the environment depends on the amount of gold and metals present in the natural ore extracted. Apart from that, the high use of machines results in higher air emission and fuel consumption. In contrast, the manual method depletes water resources and produces a huge volume of waste. It is also found that most crucial environmental impact of gold production is the minerals consumption. However, globally, gold production contributes the most to a person's yearly emission to human toxicity impact. This research presents the inventory data of the small-scale gold production which gives the better understanding of its environmental impacts throughout its life cycle. Nevertheless, there are some uncertainties and missing data. Despite of that, it is a pioneering study that provides guidelines and beneficial insight to the future research.
