search for Copper-Nickel ores

The main task of conducting geophysical, geochemical and geological works on Ulitaozerskaya square was to assess the prospects of this area for copper-Nickel and platinum mineralization, with the determination of the locations of the test wells.

The purpose of the work was to carry out detailed complex geophysical works and geological routes on a scale of 1:10,000 for sorting out geochemical anomalies that are promising for copper-nickel ores with platinum and further setting up drilling operations. Detailed complex geophysical work was a logical continuation of previous geochemical work. As a result of these previous works, a number of anomalous objects were identified that are promising for copper-Nickel and precious metal mineralization.

The purpose of the work was to conduct complex geophysical works on a scale of 1: 5000 to clarify the features of the geological structure of the ore-prospective area. Identification of zones of ore mineralization and metasomatic changes. The main geological tasks were to identify potentially ore-bearing structures in the geophysical fields for the purpose of their subsequent verification by mining and drilling operations.

1) promising ore-bearing objects are represented by pyroxenites, gabbro, which have the following geophysical parameters: RC >10000-20000 Ohms * m; PD > 3.5%, magnetic;

2) host rocks (gneiss, biotite shales, granites), including those with sulfide mineralization, are represented by low values of PK (50-1000 Ohms * m), in the PD fields are expressed implicitly from 1% to 20% and higher, weakly magnetic;

3) rocks of the kaalam Intrusive complex (diorites, gabbro-anorthosites) are expressed by average values of PK =1000-10000 Ohms*m, weakly polarizing PD < 2.5%, weakly and medium-magnetic ∆T = 200-500 NT.
