Lithium brines drilling underway at Reedy Lagoon's Nevada project
Reedy LagoonCorporation Limited (ASX:RLC) today provided an update on lithium drilling atits wholly-owned Columbus Salt Marsh Project in Nevada, USA. Extensive volcanicash deposits have been intersected in the current drill hole, indicatingprospectivity for lithium, while the presence of brine has been confirmed inaquifer above the Target Zone.
The ColumbusSalt Marsh Lithium Brine Project is one of three lithium brine projects inNevada, all of which are 100%-owned by RLC. The projects are located near NorthAmerica's only producing lithium brine operation, the Silver Peak Mine.
Drilling ofhold CBD-01 passed 750m depth late on Friday 23 March Australian time and isprogressing well towards its target depth of 1,000m.
The drillhole has intersected extensive thicknesses of locally derived clastic sedimentsand volcanic ash and tuff deposits which are interpreted to be derived from theeruption of Mt Bishop and the Long Valley Caldera 110 kilometres to the west.
Of course, as with all mineralsexploration, success is not guaranteed - consider your own personalcircumstances before investing, and seek professional financial advice[ME1] .

The blue box shows the approximate interval pump tested and sampled.Note that resistivity is the inverse of conductivity i.e. low resistivityequals high conductivity.
The MtBishop Tuff is believed to be the source of much of the lithium in ClaytonValley and the presence of extensive deposits of these tuff and ash beds in thecurrent drill hole is considered significant.
The drillprogramme at the Columbus Salt Marsh project is investigating a highlyconductive zone extending from 600m (1,968ft) to more than 1,000m (3,280ft)below surface.
A pump testwas conducted approximately 200ft (61m) above the Target Zone in order todetermine if brine is present. An aquifer within a zone of tuff and volcanicash deposits from 1642ft (500m) to 1742ft (531m) was pump tested and sampled.
The aquiferwas confirmed to be brine with an average TDS of 48,803 ppm, and EC of 53,723micro-Siemens per centimetre ( uS/cm) (average of 11 consecutive readings takenover 2.5 hours of pumping), although assay detected no lithium in the brinesampled at this level. The elevated TDS and EC detected in the brine isconsistent with the modelled MT data at this depth.
Further pumptests will be carried out within the Target Zone to test for lithium in thezone of maximum TDS and conductivity.
