X-Cal Resources Ltd.: Exploration and Development Drilling Continues at Sleeper

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 10, 2007) - X-Cal Resources Ltd. (TSX:XCL) -

The Sleeper Gold Project is progressing well on several fronts. The District Scale (30 square mile) Gold Property, located in Humboldt County Nevada, is 100% owned by X-Cal Resources Ltd.

1. At the Facilities Area: the holes necessary to publish resource numbers within NI-43-101 parameters by calendar year-end are being drilled. The Facilities Area is approximately 2,950 feet (900 meters) long and 1,300 feet (400 meters) wide. Within this area previous exploration programs had completed 178 drill holes.

During 2007 X-Cal has completed 23 reverse-circulation (RC) and 4 core holes to date. An additional 30 RC and 4 core holes are planned for this area. Expansion drilling may increase the total number of holes to be drilled at Facilities.

A recent break-through in geologic understanding has significant implications for the modeling of and possible future mining of the Facilities Area.

Detailed examination of core indicates a low-angle stratigraphic unit that appears to control mineralization. This was not recognized previously in the reverse-circulation (chip type) drilling.

Gold and silver values can be placed within the stratigraphic layer on repeated assay data cross-sections. The strata can be projected east, up-dip to the range front break and located there on the surface. The western projection passes underneath the mine pit, through significant areas of no data.

There is much work to be done, but the tonnage and low strip ratio implications for the Facilities Area are encouraging. Other target areas may be re-drilled in light of the new interpretation.

Current additional drill results for the near surface Facilities Area mineralization include:

The (2007) target for the Facilities Area is a near-surface heap leachable resource, to be combined with the above ground materials in the nearby heap leach pads.

2. X-Cal is preparing a bulk sample from the above ground heap materials for column leach tests, as part of the overall program for the mineralization located east of the mine site in the Heaps and Facilities areas.

An access road has been built on Pad #1 in preparation for a 160 ton sample to be leach tested. The objective is a publishable resource figure for the Heaps within NI-43-101 regulations, inclusive of metallurgical testing by calendar year end.

3. At West Wood: drilling is in-filling the zone of mineralization and expanding it, both to the south and west.

An indication of a possible deeper zone located directly underneath the known high-grade mineralization will also continue to be tested (see March 8, 2007 press release).

Previous work outlined a mineralized area approximately 800 feet (250 meters) long and 320 feet (100 meters) wide. Earlier high-grade intercepts at West Wood can be reviewed in the NI-43-101 technical report for the property available at www.x-cal.com or on SEDAR.

The following West Wood drill result has both in-filled and expanded the mineralization to the west.

There are significant areas of "no data" north of West Wood, parallel to the pit, in the intervening area between West Wood and the NW target, which are also prospective.

4. The NW target is located north-west of the pit, approximately 1,500 meters north of West Wood. It is one of the areas where exploration with the objective of a breakthrough new discovery is in progress. The January 2006 paper "Exploration Potential of the Sleeper Project" by Dr. Richard Sillitoe describes this and five other priority exploration targets.

Current drill core from the NW area has encountered a silicified sulphide breccia. From a geological perspective the hydrothermal alteration is apparent and encouraging. Drill testing of this area will continue.

The mine scale exploration targets described by Sillitoe will be tested in series (NW, then SW, etc).

A third drill will be added to the program at the earliest opportunity. The program is operating efficiently and can be accelerated.

Drilling, engineering and report preparation will continue throughout 2007 with the goals of: defining base resource for the project and making a breakthrough exploration discovery.

The contents of this release have been reviewed by Robert Thomason, M.Sc., who is a "Qualified Person" as defined by NI-43-101.

The Sleeper drill samples were collected following standard industry practice and were assayed by American Assay Laboratories, Inc. of Sparks, Nevada. Gold results were determined using standard fire assay techniques on a 30 gram sample with an atomic absorption finish. QA/QC included the insertion of numerous standards and blanks into the sample stream.
