The Board of Admiralty Resources NL ("Admiralty") advise that
progress continues to be made on the current diamond drilling
programme at the Mariposa iron target, where 7 out of the
10 holes planned have been drilled to a combined depth of
2130m.
The drilling is now taking place at AD-10 and platforms for
AD-08 and AD-09 are ready for the rig to move in.
A new drill hole at the La Chulula iron target has been
delineated by Goldberg Resources, the company's external
geologists, following the promising results of the high
resolution ground magnetic survey undertaken in
September 2011.
Blue dots show completed holes. Red dot shows current working hole.
Progress Report on Mariposa diamond drilling campaign
The diamond drilling ("DD") campaign commenced on 19 November
2011 and it is expected to be completed in February 2012. It
consists of approximately 3,000 m subdivided within 10 drill
holes, with a depth distribution between 255m to 350m and a
diameter of 2.5 inches (HQ diameter). Details of the drilling
done to date is shown on the table below.

thin veins, caused by the presence of faults, which confirms the geological model established by SRK Consulting Chile S.A. in the past: the ore body is composed by subvertical bodies, quite close to each other, and separated by areas with low Fe grade in which the iron is mainly located in veins with Fe grade no lower than 15% intercepted by areas in which the veins show intense Fe mineralization between 40-45%, reaching up to 50-60%.

La Chulula target was identified as the most important target
in relation to size/susceptibility by the high resolution
ground magnetic survey carried out in September 2011.
The survey identified a north/south vertical body, with
dimensions of 250 x 750m, located near the surface, with
depths up to 700m.
Taking advantage of the drilling rig currently at work at
Mariposa, a new hole of up to 600m depth has now been
scheduled to be drilled so metallurgical testing can be
performed on the sample cores as this area has not been
drilled before.
Work has already been completed to prepare the access roads
and platform for the drill rig. The approximate cost for this
hole is expected to be
US$160,000.

Execution of the DD campaign and parallel works
The DD campaign is being conducted by Superex S.A. and being
monitored by Admiralty's external geological consultants,
Goldberg Resources.
Redco Mining Engineers is conducting weekly audits upon the
drilling process as well as data interpretation and quality
control to conduct the due diligence section of the
prefeasibility study.
A sample room to store previous campaigns and this campaign's
core samples has been erected at Mariposa. The shelving and
transportation of samples is currently being undertaken.
Minor civil works are being carried out to complete the
installation of a modular office and camp site.
Yours faithfully,
Stephen C. Prior
Managing Director

About Harper South
The Harper South Project (Harper South) lies 15 km south west
of the city of Vallenar in Region III of Chile. It covers an
area of 2,498 hectares, divided in
14 exploitation concessions and where exploration work to
date has identified six anomalous targets:
Mariposa, La Chulula, Soberana, Negrita, La Vaca and Mal
Pelo.
Mariposa is the most developed target, having a currently
JORC compliant resource statement of
168 million tonnes in the inferred and indicated
categories.
An engineering mining plan to produce one million tonnes of
finished product per annum has been commissioned with Redco
Mining Engineers.
About Admiralty Resources NL
Admiralty Resources NL is a public diversified mineral
exploration company listed in the Australian Securities
Exchange (ASX: ADY) with mineral interests in Chile and in
Australia.
Admiralty's flagship project is the iron ore projects in
Chile: Harper South (2,498 Ha) and Pampa Tololo (3,455 Ha)
near Vallenar.
Both projects are located in prime locations, with close and
