Abstract

Principally, Tin exists in Nigeria as tin oxide (SnO2) called cassiterite or tinstone, which is the chief ore of tin. It is widespread metal and the earth’s crust contains about 0.0002-0.0008 per cent or 2 to 8 grams per tonne of rocks. The primary deposit is considered workable if they contain up to a minimum of about 0.3-0.5 per cent tin (3-5 kg to a tonne of ore). The aim of the investigation is to delineate the likely Tin mineralization occurrences in the study area so as to aid further exploration studies that will identify Tin rich targets worth investing resources for detail exploration project before mining. The area of investigation is typical of both the basement complex of Nigeria and the Mesozoic younger granite ring complexes which intruded the previous and covers over 80% of the study area. In assessing the mineralization potential of the research area, a preliminary geological and geochemical investigation was carried out with emphasis on the mineralization pattern and the local geology, as well as taken into consideration the location, accessibility and topography. Basically, there are two lithological (Migmatite gneiss and biotite granite) exposures encountered in the course of the mapping exercise, outcropping both within the river channel, the low-land and upland. A total of 18 soil samples and panned concentrates were taken from the accessible area with an average of 500m spacing between each profile and each sampling point. Geochemical analysis reveals that tin concentration ranges from 7ppm to 1112 ppm with a mean value of 142.89 ppm and a background value of 53ppm. The threshold value being 159 ppm, indicates that there are three (3) isolated anomalous tin values. Comparing the background value (53 ppm) with the crustal abundance (2.2 ppm), the concentration is relatively high and this is traceable to placer tin deposit from the younger granite series.
