Arcadia Minerals Ltd. announced that initial observations of raw uninterpreted renditions of data from the recently completed regional electromagnetic survey over the Bitterwasser Lithium Brines Project have revealed the existence of a number of large geophysical anomalies, some of which are associated with the Lithium-rich Eden clay pan (where a Mineral Resource was defined in clays), and displaying features that are consistent with highly conductive aqueous brine pools. A helicopter airborne survey commenced on 11 October 2022 consisting of 52 lines on a 1 km grid was completed over the southern and central portion of the Bitterwasser Lithium in Brine project area in central Namibia. Initial observations of raw uninterpreted renditions of data from the recently completed regional electromagnetic survey over the Bitterwasser Lithium Brines, have revealed the existence of large geophysical anomalies displaying features representing highly conductive aqueous brine pools.

Historical water boreholes5 drilled by farmers and tested by the Namibian Ministry of Water Affairs in the 1980's indicated geothermal activity and that there is a close relationship between the water quality, total dissolve solids (TDS) and the EM anomaly. This may indicate that the anomaly could represent a deep seated brine deposit within the Bitterwasser half-graben basin. None of these boreholes was ever tested for lithium content.

Interestingly, all the boreholes drilled are located on the edge of the anomaly, presumably focused at the location of the throw of the major lineament making up the half graben. No information is available of any boreholes drilled within the anomaly. The anomaly measures 42 km along strike with a width of 9 km, resulting in a total anomalous extent of 19,904 hectares.

Lithium in brines is mostly associated with ancient, closed basins arising from tectonic sagging, located in an arid climate, containing geothermal activity, favourable source rocks and lithium-rich sedimentary rocks (such as clays). Detailed interpretation of the data, for both Electromagnetic (EM) and magnetics would be undertaken to render a 3D model of the anomaly to aide accurate location of drill holes. Based on the results, a stratigraphic drilling program would also be implemented to verify the geology in and around the anomaly, and to conduct a drilling program to verify the lithium content of the brines.

Some of the anomalies are closely related to the lithium-rich Eden Pan, which currently hosts a JORC compliant Mineral Resource of 85.2 million tonnes at 633ppm for 286,909t Li2CO3 (LCE), and another with the Madube Pan under which mineralisation similar to the Eden-Pan was recently encountered.
