ASX ANNOUNCEMENT
11 January 2022
Results Received from Yinnetharra Pegmatite Dykes
and Exploration Update
HIGHLIGHTS
- Yinnetharra samples variations in Li, Ta, Sn and REE suggest the presence of 2-3 phases/generations of pegmatite intrusions with more detailed exploration required to target any potentially important pegmatites.
- High resolution satellite imagery has been obtained covering all Yinnetharra Project tenements, and the preliminary review indicates a lot more sampling sites need to be visited, as indicated in Figure 2 and 3.
- Options for reprocessing and acquisition of complementary datasets to identify prospective targets are being canvassed.
- A report on an initial trial processing effort is anticipated in about 10 days.
- White Cliff plans to aggressively advance the Company's lithium and rare earth element project portfolio.
- Reedy's South Gold Project drilling due to start mid-January with field crew on site preparing McCaskill's and Cracker Jack for the arrival of the RC drill rig.
White Cliff Minerals Limited (White Cliff or the Company) is pleased to provide an update on the reconnaissance samples collected during the first pass field trip to Yinnetharra (Figure 1) and the start of exploration RC drilling at Reedy's South.
The results returned from the randomly selected sites confirmed presence of pegmatites within all tenements visited and was a critical first step. High- resolution air photography subsequently acquired by the Company has confirmed that there is a lot more sampling to be undertaken across a number of potential targets.
Commenting on the field trip, White Cliff Technical Director Ed Mead said:
"Clearly, we have work to do, but no way should 14 samples be regarded as representative of >750sq km; the site visit achieved our primary objective of proving pegmatites to be present within the White Cliff and Magnet Resource Company tenements. We have acquired high (0.5m) resolution WorldView-2, 3 and Geoeye-1 satellite data (Figure 3) which with be used to plan our ongoing exploration in 2022. We look forward to getting back on the ground, and also conducting first pass programs at Gardner Range, Rat Hill, Diemals, Hines Hill and Preston River, as we press forward on Li and REE exploration."

Yinnetharra - Li/REE Project
The Yinnetharra Li/REE project consists of six tenement applications (Figures 2), within the Gascoyne lithium region, located about 100km northeast of Gascoyne Junction and 85km south of Hastings Rare Earths (ASX:HAS) world-class Yangibana rare earths project. Two of the tenement applications are 100% owned by a subsidiary company, Electrification Metals Pty Ltd (E09/2628 & 2641). The other projects within the Yinnetharra area are Wabli Creek (E09/2629), Injinu Hills (E09/2609), Weedarra (09/2608) and Sandy Creek (E9/2630) to be 100% owned subject to shareholder approval of the Magnet acquisition (refer announcement dated 23 November 2021).

Samples MTX14012 D and 14014D show some values of interest; the variations in Li, Ta, Sn and REE suggest the presence of 2-3 phases/generations of pegmatite intrusion, detailed exploration will be necessary to identify and target any potentially important pegmatites.
Exploration planning will utilise the time prior to the granting of the tenements to refine the process to define areas of interest within the 775km2 of tenement applications.
Reedy South Gold Project
Following the successful Heritage clearance survey before Christmas, exploration Reverse Circulation (RC) drilling of the McCaskill's Hill and Cracker Jack prospects is expected to commence on or about 15 January.
