Lincoln Minerals Limited is an Australian company with a portfolio of quality iron ore, nickel-cobalt, uranium, lead-zinc-copper-silver and gold projects in Indonesia and the highly prospective Gawler Craton in South Australia.
In Indonesia, Lincoln Minerals is jointly developing a small but high grade iron ore mine with target production in excess of 250,000 tpa at 63-68 percent Fe.
The Company has secure land positions, with projects close to established infrastructure, including rail and heavy haulage road networks, shipping ports, electricity networks and water services.

    Torrens

  • The Lake Torrens project (EL 3563) is located on the margin of Lake Torrens southeast of Carapateena and Punt Hill in a similar structural position along a major NNW-trending lineament.  Carrapateena (RMG/Teck Cominco) is a complex haematite breccia system containing Olympic Dam style sulphide mineralisation (178m @ 1.83% Cu + 0.64g/t Au) from 476-654m.  Drilling stopped in mineralisation.

    At Punt Hill, iron-oxide copper-gold style (bornite and chalcopyrite) mineralisation occurs within highly hematite altered Gawler Range Volcanics and hematite breccia at depths from ~750-960m.  Mineralisation occurs on coincident/semi-coincident gravity and magnetic anomalies along a regional NW-trending fault.

  • The Lake Torrens project is east of the Torrens Hinge Zone in an area where depths to Mesoproterozoic basement are traditionally believed to be >1,000m.

However, recent work by Lincoln Minerals suggests that depths to magnetic units along the NNW-trending lineament may locally be as shallow as 200m.  Magnetic units in this area are likely to be basalts within the Beda Volcanics rather than older basement. However, whatever the magnetic units are, they have been uplifted relative to the surrounding area so this structure probably represents a basement horst or anticline.

In addition to IOCGU mineralisation, the Lake Torrens project also has potential for Mount Gunson style copper mineralisation developed immediately above or along the flanks of the interpreted horst block.
