Geochemical exploration for copper, nickel, and zinc was carried out in the Longwood Range, Southland. The thick vegetation and lack of outcrops make other forms of exploration difficult. Anomalies found in the creeks draining the range were followed up with more detailed stream sampling (water and sediment) and soil sampling. Although no mineralisation was located, several chemical anomalies were found in the soil, and the method shows considerable promise for further exploration in the area.

“…The procedures used for the Nigerian project embody some modifications over those previously described in the literature (Lakin, Stevens and Almond, 1949;Almond and Morris, 1951;Lakin, Almond and Ward, 1952). The following pages give the analytical procedures as they were actually used on the samples from Nigeria and are essentially the same as those subsequently described by Bloom and Crowe.6…”

Geochemical prospecting investigations in the Nyeba lead-zinc district, Nigeria

A field study of the distribution of traces of lead and zinc in weathering products, particularly residual and alluvial soils, was made in the Nyeba lead-zinc district, southern Nigeria. Similar geochemical work in temperate climates has shown that systematic sampling and trace analysis of residual soils and other weathering products hold considerable promise as a method of mineral exploration. The purpose of the present investigation was to learn whether geochemical methods of prospecting would apply equally well in a tropical environment.The program consisted principally of detailed studies of the distribution of lead and zinc in residual and alluvial cover over known lead-zinc lodes, followed by experimental reconnaissance sampling surveys to determine the feasibility of large-scale geochemical prospecting work. A chemical kit was shipped to the field area and used for obtaining prompt analytical data to assist in guiding the sampling program.As a result of these experiments, it is concluded that the metal content of small, near-surface samples of residual soil collected at a spacing of 100 feet would be adequate to show the location of the important lead-zinc lodes of the Nyeba district, and that the metal content of deeper samples of alluvial soil collected at a spacing not greater than the width of the lode would indicate the presence of sulfides beneath alluvial cover.An all-African crew was trained to do all but a minor part of the routine work of sample collection and analysis.
