Taruga Minerals Limited ( Taruga or the Company ) is pleased to provide an update on the Manjimup Project, Western Australia. Recent review and reprocessing of historical company and government geophysical data has been completed by Taruga and geophysical consultants Southern Geoscience. This review highlighted priority target areas across the tenement package which stretches across the highly prospective Southwest terrane, along the western margin of the Yilgarn Craton. The Southwest terrane contains the nearby Greenbushes Li-Sn-Ta mine (60km) the Wheatley JV VHMS targets (5km) and the Chalice Mining-Venture Minerals JV ‘Julimar Lookalike’ Ni-PGE targets (Thor < 10 km) ( Figures 1 & 2 ).
Taruga is currently planning reconnaissance exploration which will include detailed mapping and surface sampling of laterite and outcrop geology over prospective geophysical anomalies. Infill airborne magnetics, extensional airborne EM and ground-based EM will be considered following the phase-1 reconnaissance exploration.

Local Mineralisation Styles
There are several known mineral occurrences and prospects within the project area ( Figures 1, 3, 4 & 5 ). The main style of mineralisation sought in the Manjimup project area is magmatic Ni-Cu-PGE. This is the same style of mineralisation as Chalice Mining’s Gonneville deposit within the Julimar project and at the Thor and Odin prospects of the South West Ni-Cu-PGE project located within between the Taruga central and eastern blocks. This style of mineralisation is hosted within mafic/ultramafic intrusions. The primary massive sulphide mineral assemblage is pyrrhotite-pentlandite-chalcopyrite, while the secondary (supergene) mineral assemblage is pyrite-violarite.
The exploration techniques to targets this mineralisation style include magnetic surveys as the serpentinized ultramafic rocks define magnetic anomalies and the primary massive sulphide assemblage is suitable for electrical surveys (EM and IP geophysical surveys) as the assemblage of pyrrhotite and pentlandite is conductive. Small intrusions are considered equally prospective as large intrusions.
3
If intrusions can be identified, primarily using magnetic interpretation, then surface geochemistry and electromagnetic surveying is a likely next step. Regionally, Chalice Mining has identified a large zone on the western margin of the Yilgarn craton considered prospective for Ni-Cu-PGE deposits. This is bounded on the west by the Darling Fault and on the south by the Manjimup Fault. The Manjimup project lies within this Western Margin prospective zone.
The Manjimup project is also prospective for VHMS style mineralisation as found at the Kingsley and Jack prospects located east of E70/5030. Generally, VHMS mineralisation is hosted within marine (meta) sedimentary sequences associated with felsic volcanics. The mineralisation itself can be present as massive or disseminated sulphide. The massive sulphide at Kingsley is predominantly pyrrhotite with subordinate pyrite, minor arsenopyrite, galena and sphalerite. The pyrrhotite in the ore is magnetic and conductive. The previous exploration program conducted by BHP has included airborne electromagnetic surveys with follow up ground electromagnetic surveys ( Figure 4 ), drilling and downhole electromagnetic surveying.
Lithium is produced from the Greenbushes mine approximately 30km north of the Manjimup project area ( Figure 7 ). The lithium is hosted in pegmatites. High resolution magnetics and radiometrics can be used for geological interpretation to identify pegmatite targets. Most exploration for pegmatite involves geochemical sampling and geological mapping.
Gold (Au) mineralisation is mapped to the north of E70/5031 at the Majenup occurrence and historical Nannup mine. Little information about these sites has been identified, however they appear to be associated with significant shearing along the Darling Fault.
Manjimup East (E70/5029)
The most eastern permit, E70/5029 adjoins the Chalice Mines tenure and Chalice/Venture JV tenure to the west. The permit is approximately 100 km[2] , with the Manjimup fault running east-northeast through its southern most part and a major fault / shear running southeast through the east of the permit, as can be interpreted from Figure 1 . The basement geology is interpreted as a combination of migmatite and granitic rocks, with migmatite more common in the western part of the block. Figure 3 shows a summary of the main geophysical and geochemical features in and around E70/5029.

Table 1. Rock chip samples collected from magnetic anomaly M1 within the Manjimup East permit E70/5029. Note that PGE3 includes Pt+Pd+Au.
The Odin prospect (Chalice / Venture Minerals) is a large intense magnetic anomaly associated with a local gravity high and elevated copper in surface geochemistry interpreted to be a mafic / ultramafic intrusion located at 432000 mE 6217000 mN. There is another similar feature ~8 km north of the Odin prospect (Odin North) at 434000 mE 6225300 mN.
4
The gravity anomalies from both features appear to extend east into Taruga’s E70/5029, where anomalous PGE’s ( Table 1 ) were identified from recent rock-chip sampling. Sparse regional laterite geochemical sampling has identified copper anomalism over the permit area, largely coincident with the mafic dykes in the eastern part of the block.
Taruga is evaluating the acquisition of detailed aeromagnetic (AM) and airborne electromagnetics (AEM) datasets to identify potential massive sulphide occurrences in the subsurface for follow-up investigation. The use of airborne EM has proven successful at the nearby Odin and Thor Ni-PGE prospects, and also at the Kingsley and Jack VHMS discoveries further west.

The Odin Ni-Cu-PGE Prospects (Odin North and South) Anomalies are Shown to the West of the Block, along with Interpreted Intrusions.

Manjimup Central (E70/5030)
Manjimup Central lies directly to the west of the Jack and Kingsley VHMS discoveries (BHP – Wheatley JV) and contains a well-defined mid-late-time EM conductor (EM1, Figure 4 ) along strike from these known VHMS deposits. The basement is mapped as quartz-feldspar-biotite gneiss, however detailed mapping over the tenure has not been conducted and basement is obscured by laterite and vegetation. Figure 4 shows a summary of the main mid-late time VTEM anomalies along strike from the Jack and Kingsley VHMS mineralisation which sits only 2km to the east.

Figure 4: E 70/5029 Summary. VTEM 3.74 mSec Channel Image and VTEM 3.74 mSec Channel Contours are shown highlighting mid-late time VTEM anomalies EM1 – EM3, as well as major faults. The Jack and Kingsley VHMS prospects are also Shown Along Strike from EM1, where Massive Sulphides (VHMS) have been Intersected by Historical Drilling (Cu-Au-Pb-Zn).
AEM data has previously been acquired over the entire block by the Wheatley VTEM survey and Wheatley TEMPEST survey. The VTEM survey ( Figure 4 ) is considered the better survey for detecting basement conductors prospective for mineralisation. Immediately east of the tenement lie the Kingsley and Jack VHMS prospects. The prospects have subtle magnetic anomalies and mid-late time responses in the VTEM survey. Follow up ground EM allowed plates to be modelled at Jack and Kingsley which were targeted with drilling where massive sulphides were intercepted.
6
There is a mid-late time VTEM response in the southwest corner of Taruga’s Manjimup Central Block ( EM1 - Figure 3 ) that is coincident with a subtle magnetic anomaly along strike from the Kingsley prospects. EM1 spans 1.7km long by 0.7km wide and is considered a strong exploration target for VHMS potential and will be followed up along with other smaller VTEM anomalies ( EM2 and EM3 ) in the project area.
==> picture [261 x 537] intentionally omitted <==
Manjimup West (E70/5030)
The Manjimup West block lies on the western margin of the Yilgarn Craton. The Darling Fault and associated escarpment are located at the western edge of the block. The block covers ~300 km[2] and with a northsouth strike length of ~46km. The basement is mapped as quartz-feldspar-biotite gneiss, however limited exposure has made interpretation and mapping difficult historically. A large magnetic anomaly extends over 38km coincident with the Darling Fault, within the Taruga Tenure ( Figure 4 ). Taruga XRF sampling has confirmed anomalous Cu in Mafic/Ultramafic rocks and Banded Iron Formation (BIF) which coincide with magnetic high features in the northern part of the permit. Two bullseye VTEM anomalies have been identified in the southern potion of the project area, coincident with the Darling Fault and the semi-coincident with the magnetic and gravity anomalies (Figure 5). These anomalies (EM4 & EM5) may be associated with interpreted intrusive bodies.
The Darling fault records over 500 million years of intense shearing. The local rocks are intensely deformed, and the structure is believed to have acted as a major fluid pathway for mineralising fluids. Two gold prospects lie directly north of the Manjimup West block, along strike on the Darling Fault on a similar but smaller magnetic feature that Taruga’s Darling Anomaly.

Infill Airborne magnetics to a tighter spacing is being considered to further define the magnetic features, along with ground base EM over priority areas to identify potential massive sulphide mineralisation.
