KEY SWEDISH COPPER-GOLD SYSTEM CONFIRMED IN NEW WORK BY TALGA
==> picture [71 x 45] intentionally omitted <==
~~TALGA~~ R E S O U R C E S
Talga Resources Limited (ASX:TLG) (“Talga” or “the Company”) is pleased to announce that a review of historic drill data from one of its Swedish mineral projects has confirmed a significant new copper-gold play in close proximity to Europe’s largest operating copper-gold mine, Aitik (2,760 Mt @ 0.17% Cu, 0.1g/t Au[(1)] ).
The key findings of the new work – which digitised then analysed historic drill records and assay data that was previously only in hard copy – revealed significant copper-gold grades over substantial widths at Talga’s Kiskama project in northern Sweden. This program represents the first substantial review of its 100%owned copper-gold assets in the Kiruna mining district since acquiring the Swedish assets of Teck Resources (“Teck”) 18 months ago.
Highlights include:
-
Confirmation of potentially large Iron Oxide Copper-Gold (“IOCG ”) mineralisation system.
-
Currently producing mines in the vicinity are profitable at very low grades.
-
Historic diamond drilling focused on only 1km of strike; mineralisation is open in all directions.
-
A further 7km of strike remains largely untested and forms a high priority target zone.
-
Of the 13,836m drilled (101 holes) only 27% was assayed for copper and less than 2% for gold.
-
Significant shallow, wide intercepts of copper-gold revealed including:
-
Hole 80004: from 20m depth 42m at 0.49% Cu, 0.07g/t Au incl 10m at 1.23% Cu , 0.16g/t Au from 45m
-
Hole 77001: from 16m depth 21m at 1.02% Cu , 0.25g/t Au incl 6m at 1.98% Cu , 0.54g/t Au from 16m
-
- Hole 77007: from 34m depth 66m at 0.41% Cu incl 7m at 1.24% Cu from 92m
-
Hole 72004: from 66m depth 40m at 0.68% Cu incl 5m at 1.07% Cu from 70m & 11m at 1.51% Cu from 94m
-
Hole 78016: from 8m depth 16m at 0.36% Cu , 0.45g/t Au incl 6m at 0.75% Cu , 1.14g/t Au from 16m
-
Hole 77006: from 31m depth 39m at 0.62% Cu , 0.22g/t Au
Talga Managing Director, Mr Mark Thompson:
“As a Company our primary development focus is our Swedish graphite deposits, however we were aware of the district’s high IOCG prospectivity and are pleased that these new findings confirm a substantial coppergold system at our wholly owned Kiskama project.
Additionally, Talga’s work has revealed high potential for a much larger copper-gold deposit than previously recognised. The proximity of the deposit to road and rail links to nearby mines offers potential synergies for development and we note recent moves by other companies to take land positions adjacent to Talga’s Kiskama tenement. We believe these results will open up myriad potential opportunities to commercialise value from this IOCG deposit and Talga’s entire north Sweden portfolio. Talga is now better informed to accurately pursue divestment or joint venture opportunities for the Kiskama project.”

Introduction and Background
Talga’s Kiskama copper-gold project is located in Sweden within the Fennoscandian Shield, a geological province that covers much of northern Scandinavia and western Russia. Kiskama is situated in the Kiruna mining district which hosts multiple large mining operations, including Boliden’s giant Aitik copper-gold mine (currently milling 36Mt ore per annum[(2)] ) located approximately 80km south from Kiskama (Fig 1).
Mineral deposits in this region can be highly profitable at what are considered very low grades elsewhere in the world. This is due to low power costs (hydro and nuclear) and favourable fiscal regimes combined with high quality established infrastructure. For example, the nearby Aitik open cut copper-gold mine, the largest in Europe, hosts resources of 2,760 Mt @ 0.17% Cu, 0.1g/t Au[(1)] . First Quantum’s Kevitsa mine (Finland) is another large open cut operation in the Fennoscandian Shield which currently mines a resource of 238Mt @ 0.41% Cu, 0.30% Ni and 0.12g/t Au[(3)] .
Despite this, Sweden remains relatively immature in terms of modern mineral exploration, in part due to private mineral ownership only being permitted since 1992. Exploration post-1992 was generally restricted to targeting and minor ground work, with little follow up drilling, due to the changing circumstances of the major companies involved (e.g. Phelps Fig 1 Kiskama project geology map showing Talga tenements (blue), transport Dodge was taken over by Freeport, infrastructure and selected mines, mills and deposits. Teck scaled back exploration in Europe due to the global financial crisis and Equinox changed focus to Africa). An exception was Anglo American whose persistence led to discovery of the giant Sakatti coppernickel deposit over the border in Finland in 2011.
Talga took 100% ownership of the Kiskama project in June 2012 as a result of the acquisition of a Teck subsidiary, leaving a sole 1% net smelter royalty due on future production.
While Talga has since focussed its efforts on drilling and developing the nearby graphite deposits, the Company has always considered the high potential of commercialising the copper-gold assets. This prompted the decision to digitise then fully analyse the copper-gold data.
Geology and Mineralisation
The Kiskama project is located in the Karesuando-Arjeplog deformation zone (“KADZ”), a giant structural feature that strikes through the Kiruna mining district and forms a major terrane and metamorphic gradient boundary which hosts s e v e r a l s i g n i fi c a n t m i n e r a l occurrences.

Mineralisation at Kiskama comprises chalcopyrite-pyrite-magnetite-hematite as breccia infill in association with strong K-feldspar alteration, within an extensive zone of hydrothermally brecciated felsic to intermediate volcanics of the Porphyrite Group (~1.86Ga)[(4)] .
The mineralisation has been described as a shear-hosted iron-oxide copper-gold “IOCG” style deposit[(5)] . Iron oxide copper-gold deposits are highly prized as mineral deposits due to their often sizeable dimensions and shapes being conducive to large scale bulk mining. Nisbet et al.[(6)] noted that the extensive alteration systems at Svappavaara near Kiskama are comparable to the Cloncurry district (Australia) which hosts the Ernest Henry Cu-Au deposit (Fig 2). They considered that a major Cu-Au-Ag-U deposit remains to be discovered in the Kiskama-Kiruna region.

Drilling
Talga has located and reviewed results from 101 historic drill holes (13,836m) at Kiskama. Diamond drilling was primarily carried out by the Swedish Geological Survey (“SGU”) episodically in the period 1972-80. Drilling focussed on a one kilometre long zone in the north of the tenement which defined three sulphidic lenses up to 40m wide and up to 180m vertical depth, that remain open in all directions. Sampling of the core was selective and only 27% was assayed for copper and less than 2% for gold . See Table 1 for a summary of significant copper-gold intercepts and see Fig 3-5 for plan map and sections.
Talga has procured and analysed modern geophysical data and identified a 10km long magnetic high associated with mineralisation. It is of note that one hole (78016), located 5.5km to the south of the main drilled area along this trend intercepted 16m @ 0.36% Cu and 0.45g/t Au including 6m @ 0.75% Cu , 1.14g/t Au , highlighting the prospectivity of this largely untested priority target.

Review and Next Steps
The intercepts to date are highly encouraging in the context of nearby mines, proximity to established transport solutions and geology/mineralisation styles. There is clear potential for other metals in the system to add economic credits e.g. iron in hematite/magnetite. Additionally the scope for defining new and higher grade copper-gold zones is considered high, both adjacent to the known deposit and within the 7km strike magnetic target zone.
Talga has confirmed drillcores from 95 of the 101 holes drilled are stored at the SGU’s facility in Malå. Further work on the historic drillcore should include systematic resampling for gold and copper as a cost effective way of advancing the deposit before considering new drilling to infill and extend mineralisation and test for

resource potential. Considering Talga’s graphite focus, joint venture and divestment opportunities will be sought before dedicating further resources and funds towards Kiskama.
