The geological-geochemical "follow-up" investigation of the zinc-load-copper prospect in Palanas, Kawit, Ayala District, Zamboanga City was undertaken as part of the Bureau of Mines' continuing project. Results of this investigation show the relationship of the geochemical pattern or anomaly with the general trend of the mineralized zones. These zones are mainly controlled by structures.

Although the prospect is predominantly a zinc deposit with a ratio of 2:1 in relation with the lead, the zinc content of the residual soil is below the threshold value of 100 ppm. This can be attributed to its high solubility and mobility. The presence of smithsonite in underground workings suggests that the zinc ions have undergone dissolution and redeposition.
