• Mt Mansbridge Heritage Survey Completed
• Earthworks underway with drilling scheduled to commence during October
• Mt Maitland South Assay Results
Red Mountain Mining Limited (RMX, the Company) (ASX:RMX) is pleased to provide an update for recent exploration
activities at its Western Australian Projects.
Mt Mansbridge Project
The company has recently completed a heritage surveying with members of the Tjurubalan, the Traditional Owners
of the land. Access to several prospects has been agreed with earthworks set to commence imminently with drilling
scheduled to commence in mid-October.

Rare Earth Elements
The Company recently announced several REE targets that will be tested during the upcoming drill program. The
targets were finalized during the recently completed mapping and rock chipping program and from various studies
and data acquisition programs by the Company over the past year. In summary, the following Rare Earth Element
targets have been identified by the company for drill testing (prospects are shown in Fig 2):
• Mansbridge Xenotime-Dysprosium Occurrence - Located within the Killi-Killi formation. A Xenotime-
Dysprosium occurrence within quartz veining and alteration identified during Uranium Exploration by BHP.
HREE mineralisation confirmed by recent rock chipping.
• Kylo Xenotime-Dysprosium Occurrence – A historical rock chip collected by Northern Minerals Ltd. within the
Killi-Killi Formation. The rock chip coincides with the T4 radiometric anomaly.
• Killi-Killi Unconformity Feature – Large unconformity feature to be tested as the possible source of REE
mineralization and soil anomalies which would be consistent with a geological model proffered for regional
REE discoveries.
All heritage clearance was achieved, other than for the Klli-Killi unconformity feature which contains particular
ethnographic significance.
An RC drill rig has been secured and drilling is scheduled to commence during October. The Company intends to
continue discussions with the Tjurubalan to potentially provide access to the Killi-Killi unconformity prospect during
the 2022 exploration season.

Déjà vu Prospect (Ni-Cu-Co-PGE’s)
The Déjà vu Prospect was identified and drilled by CRA between 1991 and 1993. The prospect was originally targeted
for diamond bearing kimberlites, however encountered serpentinised peridotite. Sporadic sampling and assaying
through the ultramafic intrusive unit returned several encouraging cobalt assay results between 70-100m including
0.34%, 0.32% and 0.22% Co (Previously announced 24/2/21 ASX Announcement: RMX to progress Ni-Cu-Co-PGE Target
at Mt Mansbridge). Litho-geochemical studies recently undertaken by the companies geochemical and geological
consultants highlighted the cobalt as primary magmatic related (i.e. not weathering enrichment) and also that the
anomalous Co values cannot be explained by the observed silicate minerals within the peridotite only.
A traverse of three RC holes is planned to be drilled across the intrusion. The holes are designed to provide further
geological information, intersect the prospective contacts and provide a comprehensive set of samples around the
existing cobalt anomaly.
All proposed drilling activity was successfully cleared from a heritage perspective.

Cow Creek Prospect (Ni-Cu-Co-PGE’s)
The Cow Creek Prospect consists of several regionally distinctive, generally north-north-west trending, elongated,
magnetic features. The magnetic features sit within a broader ovoid area measuring 7x7km, an area which is ringed
by further less intensive magnetic anomalies. The area has been interpreted as a mafic-ultramafic intrusive complex,
similar to what hosts the Sally Malay/Savannah Nickel Deposit owned by Panoramic Resources.
The interpreted intrusive complex is concealed below overlying sedimentary sequences of the Birrindudu Group. This
has resulted in the regionally significant geophysical anomaly never receiving any effective exploration activity.
An inversion of the magnetic data was undertaken by Southern Geoscience Consultants (SGC) recently to assist with
visualizing the geophysical feature in 3D (Fig 5.). Several magnetic features were identified from the inversion. A
number of prioritized holes have been planned to test the features during the upcoming program, to be carried out
on a phased basis subject to results of initial drilling. All proposed drilling activity was successfully cleared from a
heritage perspective.

Figure 5 – Mag Target A – Inversion Slice and Planned Drill Hole
Assays results have recently been received from the second drill hole at the Company’s 100% owned Maitland Project
located in the Murchison Region of Western Australia.
The purpose of the drill hole was to test an IP chargeability anomaly that coincides with the interpreted down dip
position of the mineralized Maitland Shear Zone (Fig 6). The geophysical survey and targets were previously
announced (ASX – Follow up drilling to test IP anomalies at Mt Maitland – 12/4/21). The Maitland South prospect is a
+500m long shear zone characterized by numerous historical workings with shallow RC drilling returning significant
intercepts: MMC001 – 7m @ 3.3g/t Au from 34m and MUDC008 13m @ 2.53g/t from 9m (previously announced
13/1/21). Drilling successfully intersected the Maitland South Shear Zone between 266.77m and 281.42m (14.65m
width).
The shear zone consisted of quartz filled breccias on the margins with strongly silica, sericite, with minor hematite
altered schist within the centre of the zone. Disseminations of pyrite were observed throughout the interval. A peak
assay result of 20ppb Au (270-271m) was achieved from the shear zone. A peak result for the hole of 50ppb Au was
returned from 261-262m. These results are considered insignificant in comparison to previously returned drill results.
