We have used Poseidon Geophysics over a period of 30 years for multiple types of projects. These have included supporting us in geotechnical investigations in undertaking resistivity surveys for powerlines, sub-stations and water pipelines and processing data for metalliferous exploration projects. We find them ideal partners in that they bring their expertise to the projects in the planning stage, before any field work is undertaken, which ensures that the investigation or exploration programme meets the Clients expectations.

Poseidon Geophysics have been a valued partner in diamond exploration in Botswana since 1982, and have performed a wide range of aerial and ground surveys in all parts of Botswana. Poseidon have acquired unrivalled experience in the search for kimberlite pipes, in environments which are often challenging for geophysics due to deep and conductive overburden or highly magnetic country rocks. Poseidon have contributed to many successful exploration programs and I am happy to endorse their work.

Aura Energy Limited has been using the services of Poseidon Geophysics (Pty Ltd) in its uranium exploration and evaluation activities in Mauritania in West Africa since 2009. Poseidon have carried out downhole gamma logging of bore holes in several extensive drilling campaigns. Most recently Aura engaged Poseidon for 2 extensive resource upgrade programmes in mid-2017. This was demanding work involving logging around 2000 holes. As the data was to be used for Measured Resource estimation it was required to be carried out under time pressure after competition of each hole and with extensive QAQC requirements. And it was done in mid-summer in the Sahara Desert! The Poseidon geophysicists operating on site were competent and cooperative and were able to provide quick turnaround in results to guide the drilling program. Aura will continue to use the services of Poseidon geophysics as the need for geophysics arises before any field work is undertaken, which ensures that the investigation or exploration programme meets the clients expectations.

The Gcwihaba Caves Project is one of the most unique and exciting projects to be found anywhere around the world. The project is a Botswana government initiative to develop a new tourist facility in the far northwest of Botswana for the benefit of the local community and for the country as a whole. The project includes the development of a number of spectacular caves which had no natural entrances which were discovered by using gravimetric surveying techniques provided by Poseidon Geophysics (Pty) Ltd. who are located in Gaborone. The application of using gravity surveys to locate caves is new in the field of geophysics and was aptly applied by Poseidon Geophysics. The methodology required laying out a grid pattern across selected areas of the extremely rugged dolomite hills where the caves were suspected to exist and then taking gravity readings which were analysed to reveal the exact location, profile and extent of the caves. The high quality of the services provided by Poseidon Geophysics and the accuracy of the data and the gravimetric surveys that were produced virtually guaranteed the discovery of the caves. The services provided by Poseidon Geophysics were at no cost to government and greatly appreciated by the team of cave explorers, the Botswana Tourism Organisation, the National Museum and the Office of the President of Botswana. Without the gravity surveys which were conducted at considerable cost, the discovery of the caves would not have been possible as the caves had no natural entrances. Consequently it was only by analysing the results of the gravity surveys in conjunction with the surface topography that made it possible to determine the best location to drill the large diameter boreholes to provide access for the cave explorers to conduct the exploration and survey of the caves.
