OPERATIONS UPDATE



London 26 July 2007.  The directors of Tarquin (AIM : TQN), the mining company
focused on copper exploration and production in Chile, wish to inform and update
the market on the following activities which have been carried out during the
quarter ended 30 June 2007.



Project Las Pascualas:



As announced on 27 June 2007, a scoping/pre-feasibility study was completed and
a summary of that study was contained in the announcement.



Exploration continued on tenements held around the Las Pascualas project option
area.



At Las Nipas, which is located five kilometres to the east of Las Pascualas, a
programme to locate additional leachable ore commenced.   Surface geological
mapping together with rock chip geochemistry has revealed porphyry style
mineralisation with anomalous copper, molybdenum and gold over an area of 80
hectares.  A strong NW - SE trending structure which crosses the zone appears to
separate dominant copper and molybdenum values to the north-east from gold to
the south-west.  Further work is planned with drilling scheduled to be completed
following final infill drilling at Las Pascualas.



Other areas to the south of Las Pascualas, where strong zones of alteration are
present, are under investigation.



The information set out above is based on data compiled by Roger Shakesby, who
is a Director of the Company.  Mr Shakesby has sufficient experience which is
relevant to the style of mineralisation and type of deposit under consideration
and to the activity which he has undertaken and consented to the inclusion of
the data in the form and context in which it appeared.
