Cross Lake Minerals Ltd.: Drilling Underway on Ruddock Creek Property B.C.; Airborne EM Survey Confirms Known Mineralization and Outlines New Targets

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - July 21, 2005) - Cross Lake Minerals Ltd. (the "Company" or "Cross Lake") (TSX:CRN) is pleased to announce that diamond drilling and surface exploration has commenced on the Ruddock Creek Property, which is located 100 km north of Revelstoke in the Kamloops and Revelstoke Mining Divisions, British Columbia. The 2005 drilling is planned to be a three phase program, firstly to locate the extension of the E-Zone of mineralization west of the E-fault, secondly to continue to define and expand the E-Zone and thirdly to test several high priority targets defined along the "Ruddock Creek Sulphide Horizon".

The E-Zone massive sulphide deposit has been traced by drilling from outcrop on the eastern end for an approximate length of 250 metres and a width of 150 metres in plan view. The shape and exact location of the Zone has now been defined right up to the E-fault. It is unlikely that the Zone will not continue west of this fault.

The significant results from the 2004 drilling program as tabulated below:

Note: Drill hole 104 is true width while drill holes 101, 102, and 103 are approximately 78% of true width. The calculated true widths of the mineralization are 87% and 91% for holes RD-04-105 and 106 and 77% and 75% for holes RD-04-107 and 108. Drill hole intersections for RD-04-109, 110 and 111 are 91, 83 and 77 percent of estimated true width respectfully.

The potential continuity of the E-Zone west of the E-Fault has been confirmed by the intersection of a limb of the E-Zone 350 metres west of the E-Fault in drill hole C-75-1, which was completed by Cominco Ltd. in 1975. This drill hole intersected 5.50 metres of massive sulphides grading 7.60% zinc and 1.53% lead. (Refer to website for drill hole locations). A second hole in 1976 was drilled over 500 meters from C-75-1 and overshot the sulphide horizon. A down hole EM survey showed an anomaly indicating the massive sulphide target offsetting hole C-75-1. The first drill hole in 2005 will be located between the previous drill holes targeting the EM Conductor between the two previous holes. At least three holes are planned to test for the western extension of the E-Zone.

In June, Cross Lake completed an airborne EM survey over the 4000 meter long Ruddock Creek Sulphide Horizon. In addition to the E-Zone, historic surface mapping has defined at least seven exploration targets defined by Zn-Pb-Ag mineralization over widths of greater than 2 meters. The airborne survey successfully identified most of these known exploration targets but most importantly also identified a number of untested high priority exploration targets. Each of these targets has an EM and Magnetic signature similar to the E-Zone and several are extensions of an existing zone of surface massive sulphide mineralization.

During the 2005 exploration program as many as possible of these exploration targets will be evaluated at surface and tested with a second small helidrill similar to the one used in 2004. Surface exploration and diamond drilling can continue later into the summer and fall as a number of the targets are a much lower elevation than the E-Zone area allowing for a much longer exploration season.

The Company is confident that the western extension of the E-Zone will be located during the 2005 drilling program and looks forward to the results of the ongoing exploration both on the E-Zone and the numerous other well defined targets along the Ruddock Creek Sulphide Horizon. Exploration work has been conducted under the supervision of the Cross Lake's Qualified Person and Vice President, Exploration Jim Miller-Tait, P.Geo. All drill core samples were analyzed at ACME Analytical Laboratories Ltd. of Vancouver.
