Castleworth Offsets Continue to Expand Gold Resource at Pan

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 19, 2005) -

More Black Stallion, Syncline, Gnarly Drilling Intercepts Mineralization in Nevada

Castleworth Ventures Inc. (TSX VENTURE:WTH) announced today that additional results from its Phase IV (2005) drill program at the 4,852 acre (more than 7.5 square miles) Pan Project near Eureka, Nevada have been received.

Current measured and indicated resources at the 100% owned Pan Gold Project are reported at 361,400 ounces and inferred resources are 140,600 ounces, both at a 0.01opt gold cut-off and are based on records from 550 rotary, reverse circulation, and diamond core holes totaling 154,391 ft that were drilled between 1978 and 2004(i).

Seventeen previously unreported reverse circulation holes in the Black Stallion, Gnarly, and Syncline areas encountered potentially economic intercepts of gold mineralization. Twenty six additional holes are being assayed and results are expected within several weeks.

Drill holes in this program were targeted on a number of soil geochemical anomalies away from the Pan Fault structure, supporting the possibility of a large number of new targets west of Pan's known gold resources.

Three areas have now been identified that show potentially mineable quantities of gold that were previously unexplored or unreported.

Results from those 17 reverse circulation drill holes are as follows:

Holes 89, 90, 91 and 92 are open to the southeast and may be structurally related/connected to the Middle Pan Zone some 800-1,000 feet southeast. The mineralization encountered in these holes is primarily hosted in Devil's Gate limestone, similar to the South Pan Deposit located one mile to the south-southeast.

Plans are currently under review for prior-to-year-end offset drilling of those holes as well as additional drilling to test the strong possibility of larger mineralized zones in the west and southwest portion of the property.

Michael Gustin, P.Geo, of Mine Development Associates, has resumed as the company's qualified person on the Pan Gold project and oversees the 2005 exploration program. Assays reported herein were conducted by ALS Chemex in Elko, Nevada using a fire assay with an AA finish.

Castleworth's objective is to create wealth for its stockholders by acquiring, exploring, and developing advanced-stage projects located within the major gold producing areas of Nevada. The Company's total land position is in excess of 10,800 acres, comprised of three projects on the Tonopah/Walker Lane Trend, two on the Battle Mountain-Eureka Trend and one on the Carlin Trend. Two of the projects have known mineralization or resources of potentially economic grade and dimension.
