Geological Summary of Holes NN2001 thru NN2208

Generally, mineralization is found in three distinct horizons of silty, weakly calcareous, claystone and with seams of blue-grey clay. Sedimentary textures are not well preserved in the chips, so the depositional environment is not clear, but it is thought to be in a lakebed environment. Rocks between the productive horizon are mostly reduced felsic air fall tuffs and tuffaceous siltstone. All holes ended in coarse cobble to pebble conglomerate or ash flow tuff. The lower tuff shows moderate propylitic alteration with replacement of mafic minerals by chlorite and disseminated pyrite.

The tables below list the intercepts of the favorable claystone unit in each of the holes in the program. All holes were drilled vertically using reverse circulation percussion drilling methods.

Hole NN2201

was collared between four strongly anomalous soil samples (2770, 2550, 3100, and 5120 ppm Li) to evaluate the apparently favorable silty claystone rocks that largely correlated with the anomalous lithium values. This hole cut significant strong lithium values and may have been collared too deep in the geologic section to catch all the favorable unit.

The photo below shows the chip trays from Hole NN2201. These photos were taken in the field as the holes were being drilled so have some illegible markings. Samples represent  5 foot (1.52 m) intervals  of the sample stream and correspond with the assay intervals.

The tables below show the summary geologic logs and significant lithium intercepts for each hole. The intercepts are based on a 1,000 ppm lithium cut off. None of the intercepts have internal dilution. In most cases, the lithium values show sharp assay breaks at the top of the interval with a trailing effect at the lower contact. This appears to be a function of a “starved” geologic basin where the low values are associated with influxes of tuffs and clastic material while the higher values show very fine sediments more diagnostic of very low energy deposition. Lithium appears to be associated with the clay deposition, reflecting that these rocks are more susceptible to alteration and mineralization, or the lithium is co-precipitated with clay or other minerals from the water column.

Hole NN2202

was drilled towards the eastern edge of the soil anomaly to a depth of 91.4 meters, 300 feet. The hole only encountered two thin zones of mineralization and hit the apparent basement ashflow tuff at 30.5 m, 100 feet. The hole was continued to a total depth of 91.4 meters, 300 feet to see if a second clay layer lie beneath the ashflow.

Hole NN2204

tested the full section of the favorable claystone package near soil values of 3700 and 2680 ppm Li to the east with values of 160 and 174 to the west. This is the typical pattern where the favorable beds are covered by the siliceous “capping tuff” .

Hole NN2206

Hole NN2207

was designed to test another exposure of the favorable claystone and strongly anomalous soil geochemistry about 790 meters south of NN2201. The hole was sited on the capping tuff unit between two highly anomalous (4870 and 4940 ppm Li) soil samples located 130 meters west and 70 meters east respectively. This hole encountered a much thicker interval of the favorable claystone than the other holes, suggesting the unit may thicken to the south and southwest of the others. Assay results are still pending at of the publication date of this news release due to staff shortages at the ALS global preparation laboratory.

Hole NN2208

was sited on anomalous soil geochemistry about 354 meters south-southwest of NN2207. This hole penetrated a total of 73 meters (240 feet) of the favorable claystone and ended in a siltstone – shale band. The hole was cut at 300 feet due to time and budget constraints and did not penetrate to the basement welded tuff.
