Excalibur Resources Ltd. Completes Drilling Program in Nye County, Nevada

NOT FOR DISTRIBUTION TO U.S. WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES
OF AMERICA


Excalibur Resources Ltd. (the "Company" or "Excalibur") (CNQ:EXBR)(Frankfurt
WKN: A0MMDH) reports that in late March 2008, the Company completed a 22 diamond
drill-hole program representing 1,535.9 meters on its Needles Property in Nye
County, Nevada. The drill program targeted portions of the Arrowhead Lineament
Fault which extends for over 3 km on the property. Drilling was primarily
conducted along the NNW-trending Arrowhead Lineament Fault in four zones that
are designated (from southwest to northeast) the Gladius, Arrowhead, Argenta and
Whopper Junior Zones.


Arrowhead Mine Area

A total of five drill holes were completed around the Arrowhead Mine area (N-52,
and N-61 through N-64). As reported in a previous News Release dated March 11,
2008, drill-hole N-61 reported a silver value of 721.69 g/t and a gold value of
2.34 g/t over a true width of 4.30 meters.


The results of the three additional holes N-52, N-62 and N-64 are reported
below. Drill holes N-62 and N-64 were drilled on the same setup as N-63. N-62
intersected the following zone:

N-63 (-75 degrees) entered a void at the bottom which is most likely a stope
from the old Arrowhead Mine. N-64 (-90 degrees) drilled from the same setup
intersected only geochemical levels of gold and silver mineralization.


N-52 (-60 degrees) was drilled 10 m south of the collars of drill holes N-61
through N-64, and intersected highly-altered volcanic rocks with 27.4 g/t Ag
over 6.74 m.

Whopper Junior Zone ("WJZ")

The WJZ is located on the Arrowhead Lineament Fault 1.3 km NNW from the
Arrowhead Mine area. Four holes (N-71, N-72, N-72A, and N-73) were completed on
the WJZ and intersected broad zones of disseminated pyrite and quartz stock-work
that is highly anomalous in gold, silver and other geochemical pathfinders
including arsenic, antimony and sulfur. The following table summarizes the
average geochemical values for each of the drill holes:

Area Southeast of Arrowhead Mine

Five drill holes were drilled on two sections south of the Arrowhead Mine. One
section was located 137 m south-southeast of the Arrowhead Mine (N-68 & N-70).
The other section was located 280 m south-southeast of the Arrowhead Mine
(N-54A, N-66 & N-67). Drill-hole N-66 (-45 degrees) intersected 2.0 g/t Au /
1.92 m.

------------------------------------------------------------------



Drill holes Needles-54A (-60 degrees) and Needles-67 (-90 degrees) drilled from
the same setup intersected only trace levels of gold and silver.


Area East of the Arrowhead Mine

Drill hole (N-65) was completed on an induced polarization anomaly located 265 m
east of the Arrowhead Mine. N-65 intersected a widespread zone of disseminated
pyrite, but only trace levels of gold and silver accompanied the sulphide
mineralization.


Argenta Mine

Drill Hole N-69 (-70 degrees) was completed adjacent to the Argenta Mine Shaft,
and was terminated early (51.15 m) owing to intense clay alteration which caused
difficult drilling conditions. N-69 potentially is a very important hole since
it is the only hole drilled between the WJZ and the Arrowhead Mine, and
intersected anomalous gold content in all 22 samples of the drill core.

Recommendation by Company Consultants

The recent drilling program has demonstrated that epithermal precious metal
deposits at Needles are hosted along the NNW-trending Arrowhead Lineament Fault
("ALF"); and occur in close proximity to epithermal quartz veins that have been
emplaced along the ALF. The recent drilling program has also demonstrated that
the ALF is a high-angle normal fault that dips steeply to the west and truncates
2 major, flat-lying volcanic cycles; a lower fragmental series of intermediate
composition and an upper tuffaceous series of felsic composition. Wide zones of
epithermal veining are more prone to formation at the contact between the two
volcanic cycles where the ALF crosscuts the stratigraphy such as the Whopper
Junior Zone.


The area between the Whopper Junior Zone and the Arrowhead Mine exposes 1.4 km
of intense hydrothermal alteration that has only been tested by one drill hole
to date (N-69) that intersected a wide zone of anomalous gold content before
being abandoned. The area is covered by volcanic rocks of the upper cycle, and
the prospective target horizon lies at relatively shallow depths below the
surface (less than 250 m). Based on the intense hydrothermal alteration seen at
surface, and persistent low levels of gold/silver mineralization seen at
surface, this area could host a large epithermal precious metal deposit that is
currently not exposed at surface.


It is highly recommended that a grid be installed on the area between the
Arrowhead Mine and the Whopper Junior Zone on 100 m line spacing and that soil
sampling, and geophysics be undertaken to identify quartz-veining and
disseminated sulfide mineralization that frequently accompany precious metal
mineralization at Needles. Targets generated in this area are considered a
high-priority, and should be tested by diamond drilling. Please refer to a
schematic longitudinal section of the Arrowhead Lineament Fault in the corporate
presentation illustrating the above discussion that can be found on the
Company's website, www.excaliburresources.ca.

Proficiency PTP-MAL, accredited by the Standards Council of Canada. American
Assay Laboratories also participates in the Society of mineral analysts-Round
