Perth, Australia (ABN Newswire) – QX Resources Limited (ASX:QXR) is pleased to confirm that numerous brine aquifers were successfully intersected in the second hole of a two-hole diamond drill (DD) program over the large scale Liberty Lithium brine project in California, USA.

– Drillhole number 2 is now complete at a depth of 443m. Brine sampling, geophysics and other activities are currently underway.

– Numerous brine aquifers* were intersected between 90m and 295m depth in drillhole 2.

Both diamond drilling holes, located 4km away, were centred around significant geophysical target in magnetotellurics that indicated a number of conductive brine bearing subaquifers.

– Drillhole 1 results and interpretations are expected by mid-February. Drillhole 2, however, will be released in late March.

*Cautionary Statement: The intersection of brines does not imply that the brines are lithium bearing. A chemical analysis by an independent laboratory will be able to determine the lithium content in a salt.

Brine sampling*and downhole geophysics of the second drill hole is underway. Packer sampling is being used to sample specific aquifers, and intervals are determined by the downhole geophysical logs and geological logs.

Drillhole 1 will have lithium assays and interpretations in the coming week, while drillhole 2, with its lithium results, is expected to be released in late March.

The second vertical drill hole was completed at 443.5 metres. At 90m, 130m 210m 245m and 295m, numerous brine aquifers with a range of widths from a few meters to 10 metres were intersected. At these same levels, running sands that are favourable for brine-aquifers were encountered. The increased salinity suggests that a favourable zone extends from 210m up to 270m.

The top of the hole was dominated by fine-grained sediments and sandy layers. Below this, gravels, conglomerates, and coarse alluvial fans were found to the bottom of the hole. The geology intersected reflected Albemarle’s anticipated target sequence, as it was similar in profile to the producing layers of Silver Peak lithium producer in Clayton Valley USA.

The second hole, which is in a favourable aquifer, will be casing with slotted casing. This will allow for further monitoring and sampling. Large brine sample volumes (>20,000 litres) will then be pumped and stored. Bulk volumes will be sent to various direct lithium extraction providers for testing and analysis (refer ASX announcement of 25 October 2023).

Stephen Promnitz (Managing Director of QXR) said: “Intersecting multiple brine aquifers is very encouraging.” The saline and running sand horizons that were encountered are exactly what is needed when looking for new lithium-brine basins. The geology in the second borehole is also very similar to that of the nearby lithium brine producers. Albemarle.

The sampling is very specific. A packer sampler is used to take samples from individual aquifers ranging in thickness from 3m to ten meters. Once collected, bulk samples will be sent to a laboratory for direct lithium extraction tests.

It’s taken a little bit longer than expected for assays to be done and to interpret the results due to issues at the end of the year, but it’s a good start to this massive Liberty Lithium target project.”

Packer Sampling

Packer sampling using “straddle” packs is being used downhole to sample specific sub-aquifers. Within the open drillhole, below the drill bit head, rubber stoppers are inflated either side of the specific aquifer between 3m to 10m, with intervals determined from the resistivity and gamma downhole geophysical log together with the geological log, where brines were identified (see Figure 2*).

Drillholes & Deal Terms

The first vertical diamond drilling hole was completed in December 2023 at a depth of 369 metres. The target horizons were intersected between 49m and 329m. Along the length of the hole, fine-grained soils, gravels, and coarse alluvial fans were intersected.

Drillhole 2 is 4km south of Drillhole 1. Both holes are located over significant MT targets interpreted to indicate a series conductive brine bearing aquifers in depth. Both holes are situated within a lithium brine anomaly surface of over 10km as defined in auger sample (see image 4).

QXR is able to earn a 75 percent interest in the 102km2 Liberty Lithium Brine Project in California (USA) (refer ASX’s announcement dated October 5, 2023). The Project is the largest lithium brine project in the USA. (For scale, it is equivalent to two times the area of Sydney Harbour). The Project’s geological setting is similar to that of Albemarle’s nearby Silver Peak Lithium brine producer in Clayton Valley USA.

QX Resources Limited (ASX:QXR) is focused on exploration and development of battery minerals, with hard rock lithium assets in a prime location of Western Australia (WA), and gold assets in Queensland. The aim is for QXR to connect end-users (battery, car makers and cathode makers) with QXR. QXR is an experienced explorer/developer and has a growing portfolio of mineral exploration projects.

Lithium portfolio: QXR’s lithium strategy is centred around WA’s prolific Pilbara province, where it has acquired a controlling interest in four projects through targeted M&A – all of which sit in strategic proximity to some of Australia’s largest lithium deposits and mines. QXR has a regional lithium tenement portfolio (both granted and under application) that spans 350 km2 across the Pilbara.

QXR’s gold portfolio includes two Central Queensland projects, Lucky Break and Belyando, which are being developed through an earn-in arrangement with Zamia Resources Pty Ltd. Both gold projects are strategically located within the Drummond Basin, a region that has a >6.5moz gold endowment.
