                                   Exploration Update



Dated: 3 August 2006



Red Rock Resources plc ('Red Rock' or the 'Company') the mineral exploration and
development company focused on advancing iron ore, uranium and manganese
projects in Australia and East Africa, reports that a announcement was issued
today to the Australian Stock Exchange by Jupiter Mines Limited ('Jupiter')
(www.jupitermines.com) in relation to the Company's Mt Ida tenement that is
under an option and royalty agreement with Jupiter. The text of that
announcement is reproduced below, and a full version with maps and photographs
can be found at the Australian Stock Exchange website (www.asx.com.au) by
entering the stock code 'JMS'.



               'SIGNIFICANT NEW IRON DISCOVERY AT CENTRAL YILGARN



•  The new high grade (+66%Fe) iron discovery confirms the Central
   Yilgarn Iron Project contains multiple high grade haematite zones.



•  The Central Yilgarn new discovery of massive blue haematite grades
   66.25% iron at surface and all impurities are low tenor.



•  This new zone is located 1.5km north of Mt Ida and 11km south of Mt
   Mason confirming Jupiter's iron ore potential.



•  Jupiter has also confirmed through mapping and surface sampling an
   additional eastern +10km continuous high grade haematite zone between Mt 
   Mason and Mt Ida grading on average over 60% Fe.



•  Production from the Central Yilgarn Iron Project is planned to be
   crushed on site, trucked to Menzies (90km) and then railed to the Port of
   Esperance.



Summary



Jupiter's recent mapping has discovered an additional Mt Mason style high grade,
blue - grey haematite zone located approximately 1500 metres north of the Mt Ida
trig. Surface sampling of rock chips assayed 66.25% Fe, 2.1% SiO2, 0.4% Al2O3,
0.4% P, 0.4% S, and a LOI of 2.6%.



This massive blue haematite discovery is very significant as it adds to the
viability of the Mt Mason iron occurrence and will add high grade tonnage to the
project.



The mapping also identified an additional haematite lens some 500m east of Mt
Mason that is continuous over all 13km to Mt Ida. All samples averaged a range
of 54.3% Fe to 63.6% Fe, however the overall iron assay was 60.2% Fe.



In physical appearance this eastern unit appears to be a shaly, haematite
enriched banded iron unit that occurs as low relief, rounded hillocks of
lateritic rubble with a spine 5 -15 metres wide of outcropping or subcropping
shaly haematite.



The assays carried out on this unit show that almost no shale is present and due
to its continuous nature it should add more tonnes to the overall prospective
future iron ore resource/reserve.



The next phase of exploration at Mt Mason/Mt Ida will be to thoroughly sample
and delineate:

1.      The new discovery of blue -grey haematite;

2.      The eastern +10km haematite unit and,

3.      Commence resource delineation.

4.      Continue scoping work.



The eastern haematite unit needs to be drill tested over its strike length as
the first stage in accurately delineating the depth and width of haematite in
the unit and to better understand the potential size and grade of the iron
occurrence here. Given the high grade of the blue-grey haematite patch this will
also need drill testing to check its size potential.



Work Program



Two areas have been mapped that require further work. The newly discovered, high
grade haematite patch north of Mt Ida needs careful mapping and some drilling to
discover potential mineralisation at depth and under cover. The eastern unit of
haematite that stretches the length of the leases needs to be tested first with
continuous chip sampling across the unit at 100 to 200 metre spacing with the
sample locations flagged and controlled with GPS coordinates.



After these sample results are evaluated a program of wide spaced (given the
strike length involved) drilling needs to be carried out to at least 20 metres
depth then followed up with closer spaced drilling as required.



Conclusion



The new high grade haematite discovery at Mt Ida has the potential to add
significantly to the high grade Mt Mason haematite occurrence and should give
the Central Yilgarn Iron Project viability.



In addition the new eastern zone will provide large tonnage and Jupiter is
targeting plus 20 million tonnes.



Additionally, iron ore can also be obtained from the well developed Kanga zone.
