The story and history of the Little Jingua Gold Outcrop holds the origin of how the Jiufen and Jinguashi regions came to be gold mining areas.Prior to large scale gold mining in Jiufen and Jinguashi, legend has it that the Kaitaglan aborigines had already obtained indirect evidence of gold. The unexpected discovery of gold in the Keelung River attracted hordes of gold prospectors. As the area gold panning area expanded up along the Keelung River, the Lee family from Chaozhou, who had worked in the gold mining industry in San Francisco went up along the Xiaocukeng Creek and discovered that it was particularly rich in gold content. After some investigation, they discovered the Little Jingua Gold Outcrop in 1894, located right at the center of a radial river system, the true source of gold appearing in the Keelung River. The gold mine deposit at the Little Jingua Gold Outcrop was formed by hydrothermal gold ore fluids in sedimentary rock. The entrance is located at the 19.5 kilometer mark of County Highway 102, accessible through the footpath. It is at an altitude of 560 meters, an oval shape approximately 30 by 20 meters in size, oriented north-south and continues down in a tubular shape. According to its form and the fact that ore excavated contains conglomerate structures, it may also be a breccia pipe itself. The center of the the Little Jingua Gold Outcrop mine deposit is composed of hard silicified sandstone and shale, with prolific veined and disseminated pyrite deposits, approximately 8g of gold content per ton. A loose clay belt lies in the surrounding area, and sometimes a bright red rock can be found near the deposit, a mixture of secondary minerals such as realgar, orpiment, hematite, and limonite.When this outcrop was first discovered more than a hundred years ago, it was named Jingua because it resembled the shape of a pumpkin.
