This work describes the reconnaissance and detailed phases of a potential copper sulfide mineralized target situated between the Sul-Riograndense Shield and the Camaquã Basin. The study area comprises the Victor Teixeira and the Capão Grande copper occurrences. These were recognized and catalogued in the 1960s by the Brazilian Department of Mining Production (DNPM in Portuguese) in the countryside of Caçapava do Sul, Rio Grande do Sul State, Brazil. These occurrences are delimited in the surface by malachite and azurite disseminated mineralizations which fill fractures and sandstone and schist pores. The initial phase of reconnaissance involved a gravimetric survey that revealed an anomaly with high amplitude between the copper occurrences. The forward modeling of this anomalous peak showed a body with significant density, which was related to chalcocite, and motivated the use of resistivity and induced polarization in the detailed phase. Our data were associated with a conductive body and three resistive and three polarized bodies. The correlation between the conductive and the polarized bodies (situated below 60 m) was associated with sulfides in the subsurface. The resistive bodies situated above the polarized ones were attributed to silicified portions in the country rocks. The combination of procedures based on the geophysical analysis in an area delimited by structural and metallogenetic control showed efficiency in the prospect of the buried target, which is a common paradigm in current minerals research.

这项工作描述了位于 Sul-Riograndense Shield 和 Camaquã 盆地之间的潜在硫化铜矿化目标的侦察和详细阶段。研究区域包括 Victor Teixeira 和 Capão Grande 铜矿。这些在 1960 年代由巴西南里奥格兰德州 Caçapava do Sul 乡村的巴西矿业生产部（葡萄牙语为 DNPM）认可并编目。这些矿点在地表被孔雀石和蓝铜矿浸染矿化所界定，这些矿化填充了裂缝以及砂岩和片岩孔隙。侦察的初始阶段涉及重力测量，揭示了铜矿之间的高振幅异常。这个异常峰的正向建模显示了一个具有显着密度的物体，这与辉铜矿有关，并促使在详细阶段使用电阻率和感应极化。我们的数据与一个导电体、三个电阻体和三个极化体有关。导电体和极化体（位于 60 m 以下）之间的相关性与地下的硫化物有关。位于极化电阻体上方的电阻体归因于围岩中的硅化部分。在由构造和成矿控制划定的区域中基于地球物理分析的程序的组合在埋藏目标的前景中显示出效率，这是当前矿物研究中的常见范式。我们的数据与一个导电体、三个电阻体和三个极化体有关。导电体和极化体（位于 60 m 以下）之间的相关性与地下的硫化物有关。位于极化电阻体上方的电阻体归因于围岩中的硅化部分。在由构造和成矿控制划定的区域中基于地球物理分析的程序的组合在埋藏目标的前景中显示出效率，这是当前矿物研究中的常见范式。我们的数据与一个导电体、三个电阻体和三个极化体有关。导电体和极化体（位于 60 m 以下）之间的相关性与地下的硫化物有关。位于极化电阻体上方的电阻体归因于围岩中的硅化部分。在由构造和成矿控制划定的区域中基于地球物理分析的程序的组合在埋藏目标的前景中显示出效率，这是当前矿物研究中的常见范式。位于极化电阻体上方的电阻体归因于围岩中的硅化部分。在由构造和成矿控制划定的区域中基于地球物理分析的程序的组合在埋藏目标的前景中显示出效率，这是当前矿物研究中的常见范式。位于极化电阻体上方的电阻体归因于围岩中的硅化部分。在由构造和成矿控制划定的区域中基于地球物理分析的程序的组合在埋藏目标的前景中显示出效率，这是当前矿物研究中的常见范式。
