The Results of EMIT Maxwell Plate Modeling of VTEM anomalies for theKAN Gold Extension Project

________________________

The Kan project is located in the Labrador Trough of Northern Quebec, approximately 85km South West of Kuujjuag, Nunavik Territory.

Early exploration on the property was initiated by Cominco Ltd. (Cominco) in 1965 with the discovery of a massive
sulphide showing located under a sphalerite-galena-pyrite, glacial boulder train. Limited drilling by Cominco at the
time failed to define the extensions of this sedimentary exhalative (Sedex) base metal showing. Work resumed in
1993-1996 by Kennecott Canada Inc. (Kennecott) and then in 1999-2000, Noranda Exploration Ltd. (Noranda).
Kennecott discovered two more massive sulphide boulder trains located within 1.5km of the original discovery. The
average grade of 28 of these boulders is 7.7% lead, 9.7% zinc, 276g/t silver and 0.65g/t gold. Dimensions of some of
these boulders reach more than 2 meters across and their angular shapes point to local sources.

While Sedex base metals were the focus of exploration work on the Kan Property, several gold showings were
recorded in the historic assessment reports. The first gold occurrences were located during a Labrador Trough
precious metals reconnaissance campaign done by Noranda in 1987-88. Six grab samples reporting grades from
1.10g/t gold to 9.20 g/t gold were collected from an iron formation ridge located 1.5km east of the Kan showing.
There was no follow-up done on these gold results and this area will be a priority target for Rio Silver.

In 1993, during base metal reconnaissance work, Kennecott discovered a quartz vein cross-cutting iron formations
located 7km NW of the Kan showing. This vein (the Ferricrete showing) reported surface channel assays of up to
280.8g/t gold over 0.30m and 143.4 g/t gold over 0.40m. Four holes were drilled under the showing to test both the
vein and the host iron formations. Results from the drilling are reported below:

K94-11: 4.14g/t Au over 3.8m
K94-12: 6.29g/t Au over 3m and 1.24g/t Au over 2m
K94-21: 5.07g/t Au over 6m and 3.64g/t Au over 4m
K94-22: 4.01g/t Au over 1m and 1.64g/t over 1m.

Drill program based on EM modeling

Posted by on Friday, 10 September, 2010

Excalibur Resources Ltd. reports that it has signed a contract with Distinctive Drilling Services Inc.  for a drill program of a minimum of 4,000 meters at the Sturgeon Lake Property.

The Company’s Sturgeon Lake Property, comprising 91 sq. km., is a Volcanogenic Massive Sulphide (VMS) and Gold and Copper prospect situated in northwestern Ontario. In March, 2010 the Company received positive results from a VTEM (Versatile Time-Domain ElectroMagnetics) survey conducted by Geotech Ltd. The VTEM survey detected areas that have coincident high conductance and high magnetic anomalies. Results from the survey are similar to the electromagnetic characteristics of known VMS deposits. The VTEM data was used to select 29 highly prospective targets based on their conductance and magnetic responses, as well as the available geological data. Geotech has further analyzed the VTEM data using Maxwell Modelling to estimate the size and dip of each of these targets.

On June 1, 2010 three additional claims approximately 2 sq. km in area were staked along a banded iron formation that runs for approximately 15 km along the northern part of the Sturgeon Lake property. This iron formation could contain gold and copper mineralization, and therefore soil samples have been taken in this part of the property to test for the presence of gold and copper. On July 2, 2010 a claim approximately 1 sq. km. in area was staked near a positive result from geophysics and geochemistry for a VMS deposit.

Excalibur’s Sturgeon Lake property is directly along strike and to the east of 6 VMS deposits that were mined between 1970 and 1991. A total of 19 million tonnes of ore was mined from these 6 VMS deposits with typical grades of 9% zinc, 1.5% copper, 140 g/tonne silver and 0.5 g/tonne gold. These 6 mines and the Sturgeon Lake property are all in the Sturgeon Lake Greenstone Belt. Another nearby past producing mine in the Sturgeon Lake Greenstone Belt is the St. Anthony Gold Mine that produced 63,310 ounces of gold at an average grade of 6.6 g/tonne.

On June 1, 2010 the Company commenced its exploration program of the Sturgeon Lake property, consisting of line cutting, geological mapping, geochemistry which, along with the Maxwell Modelling, has been used to define the drill program. The Company plans to drill a minimum of 4,000 meters during the 2010 exploration season, which will be focused on the the most promising targets. The Company is also having approximately 15 km of roads and trails constructed to extend the existing logging roads to provide access to all of the exploration targets. All exploration staff and contractors are being housed in an exploration camp that the Company has constructed on its mineral claim.

Recently, the Company announced the first set of results from geochemical surveys being carried out that include both Enzyme Leach (inorganic geochemistry) and Soil Gas Hydrocarbon (organic geochemistry) in order to discriminate which geophysical targets are associated with VMS deposits..SGH results have been received, which show strong coincident apical and halo anomalies typical of signatures from known VMS deposits. Enzyme Leach results have also confirmed the presence of metals that are characteristic of VMS deposits. The geochemistry and strong geophysical conductors and magnetic signatures in volcanic terrain along strike of 6 past producing deposits provides compelling reason for drill-testing of the identified targets. See web site at www.excaliburresources.ca for further details.

It is the Company’s belief that the results of each step of its comprehensive and systematic exploration program have provided indications of the presence of possible VMS deposits.
