OPERATIONS UPDATE

18 April 2008.  The directors of Tarquin (AIM : TQN) wish to inform
and update the market on the following activities which have been
carried out during the quarter ended 31 March 2008.

Project Puquios:

Puquios is an open-cut, heap leach SX EW project located in northern
Chile.  The project is planned to produce 15,000tpa of copper cathode
commencing in early 2010.  The completion of the bankable feasibility
study and finalisation of project financing of the Puquios project is
the major focus for the Company during 2008.

The bankable feasibility study continued.  Progress was to plan, with
the key activities undertaken being:


  * The in-fill drilling programme and associated assay work was
    completed.  Work is underway on the revised geological
    model/resource evaluation and is expected to be finished during
    the June quarter.  The closer spaced drill hole data now
    available will result in a geological model with a much improved
    confidence level.



  * The Phase 1 metallurgical test programme was completed with
    preliminary results indicating metal recoveries in excess of
    pre-feasibility study assumptions.  The final report for this
    test work is being prepared.



  * The preparation and planning of engineering flow-sheets, general
    arrangement drawings, electrical distribution requirements,
    leach-pad design and the mechanical equipment list continued.



  * Pump testing of the water well that is proposed as the major
    source of project water supply indicated a continuous flow of 40
    litres/second is available.


Detailed mine planning and cost estimation will commence with the
completion of the geological model.  However, initial vendors'
quotations for some major equipment has been received and a
preliminary cost estimate prepared.  This capital estimate is
currently approximately US$130m including pre-strip, working capital
and taxes.  Preliminary economic analysis indicates very robust
project economics over a range of copper prices.

SRK Consulting was appointed as the Independent Engineers to
undertake the independent technical review of the project.  This
comprehensive and independent due diligence of the Puquios project
will enable potential project lenders to fast-track their internal
assessment processes.

Exploration drilling commenced at the end of the quarter at Las
Nipas, a nearby significant copper-molybdenum-gold geochemical
anomaly.  Las Nipas is one of a number of exploration targets located
in close proximity to Puquios that could potentially provide
resources to supplement the supply of ore to the Puquios plant.

The target completion date for the bankable feasibility study remains
late in the September 2008 quarter.
