Lyndon Station Gold Mine

The historic Lyndon Station gold mine is located over a quartz vein system. Previous production (3 stopes and 2 shafts to a depth of 9 m) between 1952 and 1954 was 100t at 3-5oz (124g/t) (source: MINEDEX) and between 1990 and 1991 via an open cut extension to 10m with 29 tons of quartz ore @ 22g/t (source:WAMEX)

Total production from Lyndon Station Mine was 129t @ approx 101g/t Au (419 ounces Au) that by modern standards has been under explored. The property has never been drilled at depth. The location of the 27.36km2 Lyndon Exploration Licence application is shown below.

Basement geology is comprised of metamorphic, migmatites and granitoids belonging to the northwestern portion of the Gascoyne Complex. These rocks host a number of high grade quartz/gold reefs associated with multiple deformation and intrusive events.

The Lyndon Station Gold Mine is documented as lying on an east/west structure that hosts several high grade reefs. This structure appears to be partly obscured by colluvium and wind blown sand and has not been tested by modern exploration techniques including drilling within the Lyndon Licence.

IRG Lyndon Tenements

• Located in the Gascoyne Region of Western Australia approximately 300km northeast of Carnarvon.
• Gold, Silver and Copper prospects.
• A cluster of high grade workings dating back to the 1950’s previously announced. Never drilled at depth nor explored by modern techniques.
• 100% owned.
• Four contiguous tenements of 652 square kilometres.
• First two samplings in late 2009 confirm high grade gold, silver and copper rich systems.
• Skarn found, Induced Polarization (IP) program planned.
• RC Drilling program planned to determine grade and tonnage potential.

Extract from the ASX announcement Jan 19th 2010 Results of sampling:

The sampling has confirmed the prospectivity of the Company’s tenements for open pittable high grade gold and also gold, silver and base metal targets.

Eric’s Find Prospect.

High grade assays for gold (maximum 19.4g/t), silver (maximum 202g/t) and copper (maximum 6.4%) were returned from the Eric’s Find Prospect including a strong association with lead and bismuth values giving a geochemical signature for further exploration. These results show that the Eric’s Find prospect is a gold, silver and copper rich system. The size of the prospect is unknown but there is widespread quartz veining in the area.

Lyndon Station Mine.

Confirmation of high grade gold (maximum 46.5g/t) in quartz veins in narrow structures in the Lyndon Station Mine.

These results confirm the high grade gold pedigree of the Lyndon Station Mine determined from the previous sampling to a maximum of 81.2 g/t gold and including 10.9g/t and 16.5g/t reported on 14 September 2009 and demonstrate that the great majority of the gold is carried by the quartz veins.
