The lithium bearing brines were intersected at a depth of 79.25 meters and continued to a depth of 103.63 meters resulting in a width of the aquifer of 24.38 meters.
Importantly, the assay of the brine returned a high of 95.9 ppm lithium.
Given the significance of the discovery, an immediate application has been made for available water rights within Columbus Marsh.
Steve Elliott, managing director, commented:
“The Columbus Marsh result is highly significant and has the potential for large quantities of commercial lithium brines to be defined in the area.
“To the best of our knowledge this is one of the highest lithium in brine assays ever to be recorded in Nevada outside of the Clayton Valley lithium brine operation and is extremely encouraging.”
Similarities to Clayton Valley
The Columbus Marsh property is situated 40 kilometres northwest of the Clayton Valley lithium brine operations.
The brine at Columbus Marsh was confined in the aquifer in a sequence of clay, salt and tuff.
It is expected that the tuff would be relatively permeable, similar to the lithium producing tuff aquifer at the Clayton Valley operations.
Indeed, it is possible that the tuff layer is the same tuff that produces lithium at Clayton Valley.
The brine also assayed up to 3,670 ppm potassium and 1,100 ppm boron, indicating strong potential for other revenue generating commodities to accompany the lithium.
Rhodes Marsh acquisition
Caeneus Minerals has acquired 78 placer claims to cover portions of the Rhodes Marsh basin, which is located circa 15 kilometres northwest of the company’s Columbus Marsh Project.
The Rhodes Marsh Project holds many similarities to basins such as Columbus Marsh and the Clayton Valley, and is therefore highly prospective for lithium brines.
Rhodes Marsh (like Columbus Marsh, Teels Marsh, and Fish Lake) is known for historic production of borax minerals.
