Columbia Progress Report On PII Llano Colorado Project

TORONTO, ONTARIO--(CCNMatthews - July 5, 2005) - Columbia Metals Corporation Limited (TSX VENTURE:COL) ("Columbia") is pleased to provide a progress report on the work being conducted on, and planned for, it's PII Llano Colorado Project located in south-eastern Sonora, Mexico.

The PII claim was acquired, initially, to cover a high-grade sphalerite (zinc) showing in felsic volcanic rocks. Subsequent geological and prospecting work on the claim revealed several extensive gossan zones and highly oxidized areas containing anomalous values in gold, silver, copper, lead and zinc. A reconnaissance scale soil geochemical survey revealed the presence of four, partially overlapping, geochemical anomalies complemented by anomalous rock samples (previously reported Dec 29, 2004). Additional claims have been acquired to cover all of the gossan and anomalous areas. The project area now consists of nine (9), 100% owned, claims, (2,434.23 hectares).

A detailed grid, with lines at 150 metre intervals, was established over the geochemically anomalous areas and soil sampling has been conducted at 50 metre intervals on the grid. The more detailed work has confirmed the reconnaissance anomalies, has extended the anomalous areas to west and to the south and provided additional detail to the previously recognized anomalies. In the area of Buenavista Hill, in-fill lines have been established at 25 metre centres and the soil sample interval was reduced to 25 metres. More detailed work is also being carried out in the vicinity of the zinc zone to help establish the strike extent of this zone. Some of the analytical data has still not been received and much has yet to be plotted and contoured.

Systematic geological mapping and rock sampling are nearing completion. The anomalous results from two rock sample areas are presented below. A link to a more extensive table of recent rock sample results is found at the end of this news release. An additional link is also included to a generalized geological map of the property, which illustrates the location of the two most significant recent samples presented below. The results summarized are those obtained from the analysis of rock chips taken from approximately 1 metre by 1 metre portions of oxidized, weathered outcrop.

Two new gossan areas have been found to the west of the original gossan area on the Zinc Claim and an outcrop containing significant copper mineralization was located (sample number 11315) east of and apparently, stratigraphically below, the original massive sphalerite occurrence.

Sample No. Au (ppm) Ag (ppm) Cu Zn (ppm)
A 11315 0.035 48 1.45% 648
A 11316(1) 7.2 10.4 2,038 ppm 493
(1)average of 2 samples

Sample number 11316 is from a weathered, silicified, andesitic outcrop located in the east, northeast portion of the claim group.

Environmental permits have been secured and access roads to the anomalous areas have been established with the concurrence of the local ranchers. Additional permits have been applied for to permit stripping, trenching and detailed surface sampling of some of the anomalous areas. Arrangements have been made to conduct induced polarization ("IP") surveys over the presently known mineralized and anomalous areas. Geophysical survey work is scheduled to begin in late July. Diamond drill ("DD") and Reverse Circulation ("RC") drill tests of the known mineralized areas, the geochemically anomalous areas, and the likely forthcoming geophysical targets is planned for late August.

Field work was carried out by the Columbia's Mexican geological personnel under the supervision of S. Sears, P. Geol., Q.P. and J. Steers, P. Eng., Q.P.

Sample preparation was performed by the ALS Chemex sample preparation laboratory in Hermosillo; all assay work was performed by ALS Chemex in Vancouver. In addition to the routine quality control work carried out by ALS Chemex the company has established a quality control protocol consisting of the routine use of certified standards, sample duplicates and blank samples.

This news release was prepared by J. E. Steers, P. Eng., Q.P., and V. P. Exploration for the Company.
