Columbia Metals Corporation Limited: Update On Columbia Metals' PII Llano Colorado Project In Sonora, Mexico.TORONTO -- Columbia Metals Corporation Limited (TSX TSX Toronto Stock Exchange (TSE before April, 2002) TSX Transfer from Stack Pointer to Index TSX True Space Extension VENTURE:COL) the "Company") is pleased to provide a progress report on the work being conducted on, and planned for its PII See Pentium II.

The PII claim was acquired, initially, to cover a high-grade sphalerite sphalerite (sfăl`ərīt, sfā`–), mineral composed of zinc sulfide, usually containing some iron and a little cadmium.

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 eight (8) 100% owned claims (1984 hectares). A detailed grid with lines at 150 metre intervals was established over the geo-chemically anomalous areas and soil sampling has been conducted at 50 metre intervals on the grid. Only partial results have been received to date but the early returns are confirming and providing additional detail to the previously recognized anomalies. In the area of Buenavista Hill, location 1 described below, in-fill lines have been established at 25 metre centres and the soil sample interval was reduced to 25 metres. Systematic geological mapping and rock sampling are being carried out over the grid area. The property geology is proving to be considerably more complex, lithologically li·thol·o·gy n. 1.

Some recently received results are presented on the accompanying tables. A map showing the location of the zones will be posted to the company's website following publication of this news release.

The full significance of all of these occurrences is not yet understood. What is clear, is that at all locations, except location 6, where the weathering/oxidation is extremely intense, the results from both rock and soil samples are clearly anomalous at the geochemical level.

Additional results from rock and detailed soil sampling are still outstanding but are expected shortly. An additional news release will be issued as soon as the results have been received, compiled and plotted.
