ASX ANNOUNCEMENT
Drilling Commenced at Morgan’s Creek
HIGHLIGHTS:
-
2,000m Reverse Circulation (RC) drilling program has commenced at Morgan’s Creek
-
RC program will target Kipushi-Style polymetallic mineralisation and Burra-Style polymetallic mineralisation (along with associated REE’s and Critical Metals ) both associated with diapiric breccia system exposed across the project
-
Hydrothermal Hill and New Burra prospects were identified from an intensive reconnaissance sampling and mapping program which highlighted multi-element geochemical anomalies over a strike of more than 3km, along the western margin of the diapiric breccia at Morgan’s Creek, in the same geological setting as the nearby Burra Monster Mine ( 75kt Cu metal – never tested for Rare Metals) ~ 160km south, and the same geological setting as the African Copperbelt Kipushi Polymetallic Deposit ( 40 Mt @ 18% Cu Eq ~ 52% Zn Eq, includes Rare Metals mineralisation)
-
Recent Diamond drilling at Hydrothermal Hill intercepted chalcopyrite mineralisation within mafic-ultramafic intrusions, along with contact skarn alteration ( assays pending ~ late December). In addition:
-
Strong Cu, REE, Li, Co and Zn in rock chip anomalism has been returned from samples collected over Hydrothermal Hill prospect and the surrounding dolomites
-
Strong REE-Zn-Li in soils anomalism is zoned around the intrusion at Hydrothermal Hill, and over surrounding dolomites
-
Large breccia system and structural fluid pathways surrounding the prospect
-
The New Burra Prospect is a 3km linear extension (south) from the Hydrothermal Hill prospect, and is comprised of highly reactive dolomites of the Skillogalee Dolomite, known to be a favourable unit for economic metal deposition (e.g. Burra Monster Mine)
-
Reconnaissance sampling (rock chips + soils) has recently returned strong Co, REE, Li, and Cu anomalism at the Oxide Hill prospect, where recent drilling intercepted REE’s-Li-Zn-CuSc-V mineralisation, both within, and zoned around a large mafic-ultramafic intrusion
Taruga Minerals Limited (ASX: TAR , Taruga or the Company ) is pleased announce that a 2,000m RC drilling program has commenced at Morgan’s Creek, one of 7 sub-project areas within the Mt Craig Copper Project (MCCP).
Taruga CEO Thomas Line commented: “We are seeing everything an exploration team would hope to see at Morgan’s Creek. Morgan’s Creek has an analogous geological setting as the giant Kipushi polymetallic deposit in the Central African Copperbelt, which boasts 40Mt @ 52% Zn equivalent, and that of the nearby Burra Monster Mine which was the world’s largest operating Cu mine during its peak. These are just a few examples of deposits which are associated with the rare diapiric breccia systems which dominate Morgan’s Creek, and we know that at least some of these deposits contain rare metals (such as REE’s and Critical Metals) like we are seeing at Morgan’s Creek. The combination of strong geochemical anomalies with strong geophysical support, along with encouraging drill intercepts from recent RC and diamond drilling, has highlighted new priority drill targets at Morgan’s Creek that we are very excited to test.”

The magnetics data allows us to see magnetic bodies such as intrusions, and areas of magnetic (and nonmagnetic, or remnant magnetic) alteration which may be related to mineralisation. Together, gravity and magnetics form core exploration tools which enhance targeting efficiency.

The Gravity data has highlighted different lithologies and structures in the subsurface, and together with the magnetics allows us to see areas of alteration and potential mineralisation, which causes variations in density and magnetism.

Mineralisation and rocks are exposed from surface at MCCP, allowing a full spectrum of exploration techniques to be used in order to asses and prioritise targets. The MCCP has the ideal source rocks and trap sites for metal deposition, which is a result of a combination of geological factors, summarised below:
Prospective Geological Features and Deposit Associations at MCCP:
ASX:TAR
-
A major structure (the Worrumba Anticline) extending the full length of the project. This has acted as a major fluid pathway for metalliferous fluids, and a conduit for intrusive igneous rocks and intrusive diapiric breccias to reach the surface and react with younger host rocks, depositing metals.
-
Over 60 recorded copper occurrences, and over 30 historical artisanal and small-scale copper mines at surface.
-
A large diapiric intrusive breccia system spanning the full 34km strike of the project, which has intruded along the Worrumba Anticline.
-
Nearby significant deposits associated with diapiric breccias include:
-
Burra Monster Mine ( 75kt Cu metal );
-
Beltana high-grade zinc deposit ( 1Mt @ 29% Zn );
-
Blinman Cu deposit (10kt Cu metal produced).
-
-
Global significant deposits associated with Diapiric breccias include:
-
Kipushi Polymetallic deposit – Congo ( 40Mt @ 10% Cu, 18% Zn, 1% Pb and 160g/t Ag )
-
Tunisia Zn-Pb deposit ( 5Mt Zn+Pb metal produced) Northern Africa
-
▪ Reocin Zn-Pb-Ag ( 87Mt @ 11% Zn, 1% Pb ) Northern Spain
-
-
Common presence of Neoproterozoic Callana Group mafic volcanics, which are known to be a source rock and host rock for significant Cu mineralisation within diapiric breccias throughout the Adelaide Fold Belt.
-
Basal unit of the highly reactive Skillogalee Dolomite is present throughout the MCCP, and in places contacts on the margin of the diapiric breccia, forming the same setting as the nearby Burra Monster Mine ( 75k Cu metal produced).
-
58km of outcropping reduced black shales of the Tindelpina Shale Member (basal unit of the Tapley Hill Formation) along a rift margin environment, extending from the Wyacca Prospect, where high grade copper has been intercepted by recent drilling. This setting is an analogous to the Central African Copper Belt deposits, and Kuperschiefer Cu ore-host lithology, along with the nearby Mt Gunson and Windabout Cu-Co-Ag deposits.
-
Nearby relevant sed-Cu deposits hosted within Tapley Hill Formation include:
-
Mt Gunson (75 kt Cu metal produced +Co + Ag)
-
Windabout (250kt Cu metal equivalent: Cu + Co + Ag)
-
-
Globally relevant sediment-hosted Cu deposits include:
-
Kamoa ( 760 Mt @ 2.73% Cu ~ 20Mt contained Cu metal) Congo
-
Kuperschiefer deposits ( 32 Mt Cu metal and 3.1 Billion Oz Ag metal collectively)
-
-
Differentiated/layered mafic-ultramafic intrusions identified at Morgan’s Creek. The geological setting at Morgan’s Creek is that of a Continental Rift setting. Significant deposits associated with layered mafic-ultramafic intrusions in Continental Rift settings include:
-
Ni-Cu-PGE + Cr/V (Scandinavia)
-
Pechenga ( 339Mt @ 1.18% Ni, 0.63% Cu, 0.3g/t PGE )
-
Penikat ( 15Mt @ 7.8 g/t Pt+Pd )
-
-

- Voisey’s Bay ( 124.4 Mt @ 1.66% Ni, 1.19% Cu and 0.13% Co
-
Vanadium (Australia)
-
Speewah ( 4,712 Mt @ 0.3% V2O5 )
-
Gabanintha ( 131 Mt @ 0.9% V2O5 )
-
ASX:TAR
- Windimurra ( **235 Mt @ 0.49% V2O5** )

- Julimar (Resource pending – N-Cu-Au-PGE; Discovery hole **19m @ 2.6% Ni, 1.0% Cu, 8.4 g/t Pd and 1.1 g/t Pt** )
-

-

-
Wyacca (sediment-hosted Cu)

-
Hawk (Sediment-hosted Au-Cu)

Greens + Schute (sediment-hosted Cu; Alkaline igneous REE, Ionic clay REE’s)
The MCCP is situated within the Adelaide Fold Belt ( AFB ), and lies at the intersection of the G2 and G8 structural corridors (lineaments). The G2 and G8 lineaments mapped by O’Driscoll led to the discovery of Olympic Dam, and reflect the deep lithospheric structure of Australia, hosting the majority of South Australia’s major base metal deposits. The AFB has hosted over 800 historical copper mines or workings, and multiple polymetallic mines since the 1840’s. Copper-gold associations are common within the AFB, with many of the old copper mining ventures not recognising the presence of gold and other metals which were not assayed for. Modern exploration has continued to uncover significant large-scale, polymetallic, base and precious metal potential around historical mining regions within the AFB, which have undergone limited exploration and development since initial mining ceased in the late 1800’s.
