Commenting on the new discovery at Mount Lindsay, Venture Minerals’ Managing Director Andrew Radonjic, said:
“Immediate success from the first exploration drilling at Mount Lindsay since 2013, has seen the discovery of a substantial skarn system immediately along strike from one of the world’s most significant and high-grade tin mines (Renison Bell Mine) and adjacent to Venture’s Mount Lindsay Tin Deposit located within Australia’s premier tin district.
The discovery of a potential new tin-bearing skarn system so close to the Company’s flagship tin deposit delivers Venture an excellent opportunity to add to the already significant resource base at Mount Lindsay. Consumers and investors are becoming extremely focused on ESG-compliant sourcing of tin, Mount Lindsay is well positioned to meet this demand, being in a ESG compliant jurisdiction, with access to renewable hydropower, combined with the Company’s commitment to minimizing its carbon footprint, through planned underground mining and processing strategies”.
Venture Minerals Limited ( ASX: VMS ) (“ Venture ” or the “ Company ”) is pleased to announce that recent exploration drilling at Mount Lindsay on the Priority Tin Target delineated along strike from the High Grade Renison Bell (Renison) Tin Mine (one of the world’s largest and highest grade tin mines) successfully intersected in ML337, 16 m of potentially tin bearing sulfide rich, magnetite skarn within the extension of the Renison Mine Sequence (host to the High Grade Renison Tin Deposit).

The Renison Tin Mine has seen mining span over three centuries[1] . Previous exploration at Mount Lindsay identified potential tin targets located within the carbonate units correlated with the Renison Mine Sequence of the upper Success Creek Group and potentially the extension of the same fault zone (Federal-Basset Fault) that hosts the Renison Mine only 12 kms along strike to the southeast (Refer Figure 6) . The Renison tin deposit is a major carbonate replacement and skarn system with significant pyrrhotite associated with cassiterite mineralisation[2] , hence Venture believed that the airborne EM survey conducted in 2019 (Refer to ASX Announcement 12 December 2019) would be an ideal exploration tool to lead to a discovery of Renison style tin mineralisation.
The follow-up diamond drilling program was designed to test EM anomalies identified within the Renison Mine Sequence in the Mount Lindsay area, with ML337 specifically targeting a coincident EM and surface geochemical anomaly (with a nearby significant historic alluvial tin field), favourably located on highly prospective carbonate units that typically dominate the Renison Mine Sequence ( Refer Figure 4 and to ASX Announcement 12 December 2019) ).
The ML337 intersection comprising 16 m (downhole) of sulfide and magnetite dominated mineralisation within a >150 m thick (downhole) calcsilicate alteration halo typical of the mineralisation style seen in the Company’s adjacent Mount Lindsay Deposit and confirms Venture’s priority target rating. ML337 shows the Renison Mine Sequence is approximately 250 m thick in the Mount Lindsay area and includes at least five major carbonate (dolomite/marble) units prospective for carbonate replacement and skarn tin, tungsten and magnetite deposits (Refer Figures 4 & 5) . Venture’s project tenure includes 10 km strike extent of the Renison Mine Sequence.
The Mount Lindsay style of mineralisation is strongly zoned and following the discovery of the new skarn system, Venture has immediately committed to a downhole EM program to identify more sulfide rich targets while the Company awaits assay results from ML337.
The Mount Lindsay Project is already classified by the Australian Government as a Critical Minerals Project[3] with an advanced Tin-Tungsten asset which is significantly enhanced by the discovery of a new skarn zone and high priority drill targets within the Renison Mine Sequence in the Mount Lindsay area. Mount Lindsay is already one of the largest undeveloped tin projects in the world, containing in excess of 80,000 tonnes of tin metal and within the same mineralised body a globally significant tungsten resource containing 3,200,000 MTU (metric tonne unit)[4] of WO3 ( Refer Table Three ).
Tin is now recognised as a fundamental metal to the battery revolution and new technology ( Refer Figure 7 ) and the International Tin Association is predicting a surge in demand driven by the lithium-ion battery market of up to 60,000tpa by 2030 (world tin consumption was 328,400t in 2020[5] ).

Reporting to two significant figures. Figures have been rounded and hence may not add up exactly to the given totals. Full details of the Note: estimate are in the ASX release for the Quarterly Report on 17 October 2012. This information was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported.
Notes:
-
The Sn equivalent formula used to calculate the Sn equivalent values for the Main and No.2 Skarns is as follows: Sn Equivalent (%) = Sn% + (WO3% x 1.90459) + (mass recovery % of magnetic Fe x 0.006510) + (Cu% x 0.28019). Whereas for the Sn equivalent formula used to calculate the Sn equivalent values for the Stanley River South and Reward Skarns is as follows: Sn Equivalent (%) = Sn% + (WO3% x 1.65217) + (Cu% x 0.34783);
-
The mass recovery of the magnetic iron is determined mostly by Davis Tube Results (“DTR”);
-
The Sn equivalent formulae uses a tin metal price of US$23,000/t, an APT (Ammonium Para Tungstate) price of US$380/mtu (1mtu =10kgs of WO3), a magnetite concentrate price of US$110/t and a copper metal price of US$8,000/t;
-
Pilot scale metallurgical testwork has been completed on the Main and No.2 Skarns with results indicating the metallurgical recovery for tin is 72%, for WO3 is 83%, for iron in the form of magnetite is 98% and for copper is 58%. The results of this testwork are stated in the ASX release dated 31 August 2012;
-
It is the Company’s opinion that the tin, WO3 and copper as included in the metal equivalent calculations for the Stanley River South and Reward Skarns have a reasonable potential to be recovered for when the Mt Lindsay Project goes into production.

About Venture
Venture Minerals Ltd (ASX: VMS) is entering an exciting phase as the Company moves from a highly successful explorer to producer with the booking of the first shipment for early September 2021 from the Riley Iron Ore Mine in northwest Tasmania. At the neighbouring Mount Lindsay Tin-Tungsten Project, higher Tin prices and the recognition of Tin as a fundamental metal to the battery revolution has refocused Venture’s approach to developing Mount Lindsay. Already one of the world's largest undeveloped Tin-Tungsten deposits, the Company has commissioned an Underground Scoping Study on Mount Lindsay that will leverage off the previously completed feasibility work. In Western Australia, Chalice Mining (ASX: CHN) recently committed to spend up to $3.7m in Venture’s South West Project, to advance previous exploration completed by Venture to test a Julimar lookalike Nickel-Copper-PGE target. At the Company’s Golden Grove North Project, it has already intersected up to 7% Zinc, 1.3% Copper and 2.1g/t Gold at Orcus and has identified several, strong EM conductors to be drill tested along the 5km long VMS (Volcanogenic Massive Sulfide) Target Zone, along strike to the world class Golden Grove Zinc-Copper-Gold Mine. Venture recently doubled the Nickel-CopperPGE landholding at Kulin by securing two highly prospective 20-kilometre long Ni-Cu-PGE targets.
COVID-19 Business Update
Venture is responding to the COVID-19 pandemic to ensure impacts are mitigated across all aspects of Company operations. Venture continues to assess developments and update the Company’s response with the highest priority on the safety and wellbeing of employees, contractors and local communities. Venture will utilise a local workforce and contractors where possible, and for critical mine employees that are required to fly in and fly out, Venture has obtained the appropriate COVID-19 entry permits into Tasmania.

| Stanley Reward and the adjacent Mount Lindsay in the early 1900s with minor small-scale open-cut and underground tin mining occurring to about 1932. Production records are incomplete, but included at least 59.8 tons of lode tin from Mount Lindsay, and at least 79.6 tons of alluvial tin. Exploration for skarn and carbonate replacement tin mineralisation was resumed in the 1960s by several mining and exploration companies, most notably CSR Ltd, Aberfoyle Tin Development Partnership and Renison Ltd, and continued until the mid 1980s. |
||
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Mount Lindsay – Stanley River magnetite-tin-tungsten deposits are hosted by the Neoproterozoic Success Creek Group and Crimson Creek Formation within the southern contact metamorphic aureole of the Meredith Granite. The Meredith Granite is part of a suite of Devonian granites which is very important to tin-tungsten mineralisation in Tasmania, and deposits associated with this suite include the Renison Bell and Mount Bischoff tin mines, the Cleveland tin and copper mine, and the King Island tungsten mine. • Exploration indicates the presence of at least eight magnetite-tin- tungsten skarn, greisenized skarn and carbonate replacement deposits in the Mount Lindsay – Stanley River area. Resources are reported here for the Main and No.2 deposits which are hosted by calcareous sandstone horizons within the Crimson Creek Formation, and the Reward and Stanley River South deposits within dolomite and conglomerate of the Renison Mine Sequence, upper Success Creek Group and lowermost Crimson Creek Formation. |
