Mat-I Project: Gold Prospects
Geology consists of ultramafics, sediments and volcanic tuffs intruded by intermediate porphyry intrusives. The Mat-I area was an important artisanal gold mining area and thousands of miners won gold from alluvials as well as shallow, hard-rock workings. There are spectacular examples of high-grade epithermal veins. However, most of the highest potential ground was lost in land disputes to other parties.
Systematic geochemical surveys by Mindoro defined four moderate-order copper in soil anomalies of greater than 100 ppm and up to 268 ppm. Maximum dimension is approximately 2,000 meters by 200 to 300 meters. Minor associated gold anomalies are present, as well as very strong arsenic anomalies of up to 1,520 ppm. The copper anomalies may reflect intrusive-related mineralization of potential interest. Further geological investigations are planned.
