Wyemandoo Pegmatite Loop Priority Target
-
The Loop Pegmatite area located in the central Fairway Pegmatite corridor contains highly anomalous lithium and rubidium rock chip assays
-
A total of 22 pegmatite rock chip samples taken around the loop pegmatite had an average of 1.06% Li2O and 0.94% Rb with samples reporting up to 2.6% Li2O and 1.7% Rb.
-
Satellite imagery suggests a similar structure lies immediately to the south in a swarm of pegmatitic dykes
The Wyemandoo “ Loop Pegmatite ” structure located in the central corridor of the “ Fairway Pegmatite Field” contains lepidolite micas with anomalous lithium and rubidium assays that highlight the potential of the area for mineralisation. Pegmatites like the “ Loop Pegmatite ” structure are in the more distal areas from the parental granitic magma’s giving rise to fractionation and the potential for enriched Li, Rb and Cs metals. Sampling in and around the “Loop Pegmatite” and surrounds found over half the 22 samples analysed have >1% Li2O (up to 2.6% Li2O) and an average grade of 1.1% Li2O, which is within the range of typical lithium economic grades. Rubidium assays are above those typically found in LCT pegmatites with an average of 0.94% with values up to 1.7%. Caesium values average 262ppm with values up to 542ppm.

The Pegmatite corridor appears to be at least 10km long and up to 6km wide with lepodolite (Li) micas found in in several locations in the central fairway and a large section of the pegmatite bearing zone has the potential to be highly fractionated and enriched with the lithium suite of metals. Aldoro will

27 October 2021 be targeting this zone in the next phase of rock chip sampling across the “ Fairway Pegmatite Corridor” .
The Wyemandoo pegmatites generally trend NE and can strike over 1000m in length, vary from 1m to 20m in outcrop width with shallow to moderate dips, typically 30 to 60 degrees. While generally linear and sub parallel to the strike of host gabbro’s, the dykes show a range of morphologies including undulating, segmented en echelon style, pinch and swell as well as bifurcating. The Wyemandoo pegmatite swarm appears to cover a large area, a northeast corridor over 10km long and up to 4km wide where the full extent is masked by young alluvium and colluvium cover.
The Wyemandoo pegmatites represent a new Li-Rb bearing lepidolite pegmatite field, located over 25km north-northwest from the Youanmi Pegmatite Field. Anomalous Li- Rb bearing lepodolite rock chip samples have been taken over some 9km with planning underway to infill and extend sampling across the interpreted pegmatite corridor. The Wyemandoo Pegmatite Field will be a focus of investigation in the coming months.

Competent Persons Statement
The information in this announcement that relates to exploration data and results derived from open file reports and information supplied by the current licence holder has been prepared in accordance with the 2012 Edition of the Australian Code for reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC). The data was reviewed and compiled by Mr Mark Mitchell, a geological consultant to Aldoro Resources Ltd. Mr Mitchell is a Registered Professional Geoscientist (No.10049) with the Australian Institute of Geoscientists and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Mitchell consents to the inclusion in the release of the statements based on his information in the form and context in which it appears.
About the Wyemandoo Pegmatite Field
The Wyemandoo Project, 80km southeast of Mount Magnet, covers 259.78km[2] on granted licences E57/1017 and E59/2431 and applications E58/571 and E58/555 forming a contiguous belt along the margin of the -Windimurra Igneous Complex. Aldoro have agreements over licence applications ELA58/571 and E58/555 which both lie within the pegmatite corridor. The project is a rare metal exploration project in an Archean layered mafic intrusion cut by numerous pegmatite dykes. There is also an extensive zone of high-grade hydrothermal tungsten (scheelite) veins. Several pegmatites have been mapped and sampled in granted licences.

| • A small number of geochemical samples, including stream |
|||
| sediments, rocks and possibly soils, have been collected within the | |||
| current licence area but were not analysed for any elements | |||
| relevant to our current work. | |||
| • As far as we are aware, no exploration drilling on pegmatites has |
|||
| ever been carried out within the current licence area | |||

| • | The licence area is underlain by gabbroic rocks of the Wyemandoo | ||
| layered mafic intrusion. The Wyemandoo mafics are separated from the | |||
| main Windimurra mass by a major fault zone and a sliver of felsic and | |||
| sedimentary schists. The layering trend at Wyemandoo is very different | |||
| from that of the main Windimurra mass. It generally strikes east-north- | |||
| easterly, and dips to the north. Metamorphic grade at Wyemandoo is | |||
| possibly higher than at Windimurra | |||
| • | There are numerous pegmatite dykes at Wyemandoo. Some contain | ||
| lithium mica. Composite rock samples from the pegmatites have given | |||
| assays up to 2.6% lithium oxide, 276 ppm tantalum, and 3296 ppm | |||
| tungsten (0.42% WO3) | |||
| • | The nearby granite pluton, immediately east of the licence area, is | ||
| probably the parent source of the pegmatites this granite is named as | |||
| part of the Wogala Suite. It is described as a metamorphosed | |||
| monzogranite containing muscovite and biotite and local accessory | |||
| fluorite | |||
| • | In a geochronology report (Wingate 2015) the same granite is said to be | ||
| part of the Tuckanarra Suite and a sample of it from near the north- | |||
| eastern corner of the current licence area is described as biotite |

| • | Topaz, fluorite, beryl, lepidolite and trace tantalite have been recorded | ||
| at Mount Wyemandoo not far from the project area (suggesting strong | |||
