This research has investigated the mode of occurrence of mineral deposit in Iperindo and its environs with integrated geophysical techniques. Total magnetic intensity map was enhanced by reduction to equator filter, magnetic susceptibility filter and analytic signal to suppress background noise and accentuate magnetic bodies within the field. 3-D Euler deconvolution and radial spectral analysis were both applied to locate and estimate the depth to magnetic anomalous bodies, suspected to host the mineral deposits. The magnetic deposits have a varying depth from 20 to 300 m. Two hundred and twenty-one (221) vertical electrical sounding (VES) stations were occupied to delineate geologic structure which could host mineral deposits within the study area. Quantitative interpretations of the VES curve revealed maximum of five (5) subsurface layers such as top soil, weathered layer, fresh basement and fractured basement. Combined vertical electric sounding and horizontal profiling (VES&HP) was acquired concurrently with induced polarization (IP) using dipole–dipole array to highlight areas with disseminated mineral deposits. The results revealed varying high and low resistivity anomalies across the study area. The observed high resistivity indicates the presence of quartz veins suspected to be hosting sulphide within schist. Areas with relatively low resistivity are suspected to be fault/fracture zones with a depth of 150 m of varying length, which are in agreement with high chargeability zones, indicating disseminated mineral deposits within the faulted/fractured zones. Delineated magnetic anomalies trend northeast–southwest direction implying geologic structures as a result of Pan-African orogeny, which were impregnated with mineralised bodies.

本研究采用综合地球物理技术研究了伊佩林多及其周边地区矿床的赋存方式。通过减少赤道滤波器、磁化率滤波器和分析信号来增强总磁强度图，以抑制背景噪声并突出场内的磁体。3-D 欧拉解卷积和径向光谱分析都被用于定位和估计磁异常体的深度，怀疑是矿床的宿主。磁性沉积物的深度从 20 到 300 m 不等。占用了 221 (221) 个垂直电测深 (VES) 站来描绘可能在研究区内拥有矿床的地质结构。VES 曲线的定量解释显示最多五 (5) 个地下层，例如表层土壤、风化层、新鲜基底和破裂基底。垂直电测深和水平剖面组合 (VES&HP) 与使用偶极-偶极阵列的激发极化 (IP) 同时获得，以突出具有浸染矿床的区域。结果显示整个研究区域存在不同的高电阻率和低电阻率异常。观察到的高电阻率表明存在石英脉，怀疑在片岩中含有硫化物。电阻率相对较低的区域被怀疑是深度为 150 m 不同长度的断层/断裂带，这与高带电带一致，表明断层/断裂带内有浸染的矿床。
