Mineralization Extended Over One Kilometre at Linear Metals' Cobre Grande Project

TORONTO, ONTARIO--(Marketwire - Nov. 8, 2007) - Linear Metals Corporation (TSX VENTURE:LRM) is pleased to report that drilling has substantially extended both the North and South Zones at its Cobre Grande project, located in Oaxaca, Mexico. The combined strike of the two zones is now over one kilometre in length. Highlighting the most recent drill results are significant intervals of copper and molybdenum including:

- CG-42B (North Zone): 28 metres of 1.18% copper and 73.95 metres of 0.094% molybdenum; and

- CG-47 (South Zone): 40.35 metres of 1.36% copper and 115.54 metres of 0.092% molybdenum

The original 10,000 metre 2007 drill program is complete and has been extended by an additional 10,000 metres with two drills currently active. Assay results from drill holes CG-42B, CG-44, CG-45, CG-46, and CG-47 have been received, all with significant intercepts which are summarized in the table below (a drill hole location map is available on the Company's website at

Note 1: the intervals in the table are based on core lengths and not true
widths of the zone, however, all holes are west directed angle holes and
have mineralized widths believed to approximate the width of the
mineralized zones. All holes are drilled down steep slopes; consequently,
depths of the intercepts below the surface are less than the metres
indicated down hole (e.g. the top of the copper zoned in CG-42B is at a
vertical depth of 130 metres).

Drill hole CG-42, which was twinned by CG-42B, was lost in a cavern prior to reaching the skarn target and is not reported in the table. Results are pending for hole CG-43, as well as holes CG-48 to CG-55.

Increased Strike to the Mineralized Skarn

Drill-hole CG-42B is a 130 metre step-out to the north of CG-40B reported previously (96.31 metres of skarn averaging 1.76% copper, 0.070% molybdenum, 0.55% zinc and 60.0 grams per tonne silver) and CG-46 is an additional 100 metres north of CG-42B. Together these holes have extended the North Zone by 230 metres for a total strike of 380 metres which is still open to the south and potentially still open to the north despite the lower grades and widths encountered in CG-46.

In the south, CG-44 and CG-45, were west directed holes drilled 600 and 560 metres south of hole CG-41, reported previously (105.5 metres of 1.01% copper, 0.033% molybdenum and 12.1 grams per tonne silver) and which was the first west directed hole drilled in the South Zone. The similarity in the results of CG-44 and CG-45, along with the mineral zoning seen in all west directed holes, gives encouragement that mineralization is more consistent along strike than previously thought. These two holes have extended mineralization in the South Zone 200 metres to the south for a total strike length of 700 metres.

Importance of Molybdenum

Hole CG-47, drilled 150 metres north of CG-45, and 400 metres south of CG-41, has encountered the best molybdenum intercept to date at Cobre Grande with 115.54 metres of 0.092% molybdenum. Previous drilling returned several molybdenum intercepts in the range of 0.07% to 0.1% and were assumed to be related to small higher grade zones of limited economic significance. The program of west directed holes has changed this assessment and shows that stockwork quartz veining at the base of the skarn is continuous along the strike of the skarn in its footwall and consistently carries plus 0.04% molybdenum. More significantly, there appear to be core areas, in both the North and South Zones, where molybdenum in stockwork approaches or exceeds 0.1% molybdenum over 50 to 100 metre widths. Vice President of Exploration, Robert Page, comments "the current phase of drilling, with its emphasis on west directed angle holes, has clarified the mineral zoning picture at Cobre Grande. These holes pass from unaltered limestone in the east, successively through zinc skarn, copper skarn, copper-molybdenum quartz-stockworked skarn and finally into molybdenum dominated stockworks in skarn or porphyry in the centre of the system. The surprise in this program has been molybdenum. The significant molybdenum mineralization intersected at Cobre Grande adds an exciting dimension to the discovery. The identification of the molybdenum stockwork zone, adjacent to the copper skarn, is very attractive and could have a significant impact on the economics of the project".

Current Program

Linear Metals is currently drilling holes on sections spaced 100 metres apart over a strike length of 1400 metres in preparation for a 43-101 compliant independent resource calculation to be completed in March 2008. The drilling of outlying targets, like the outcropping Northwest Skarn, will be delayed until delineation drilling on the North and South Zones has been completed.

The Quality Control program at Cobre Grande is supervised by Linear Metals' Senior Resource Geologist, Geoff Chinn, P.Geo., who is a Qualified Person as defined under National Instrument 43-101. Drill core is sawn in half on site and samples collected over 1 to 3 metre intervals based on geology. Prior to shipping sealed sample bags are stored in a locked facility on site at the project. Samples are shipped via air to the ALS Chemex sample preparation facility in Guadalajara, Mexico. The Guadalajara prep facility then sends pulps to the ALS Chemex Vancouver, B.C. laboratory - ISO 9001-2000 registered. All samples are assayed for silver, copper, zinc, lead, and molybdenum using 4 acid digestion and ICP-AES analysis. In addition, samples from oxide zones are further analyzed for copper and zinc solubility. For copper, there is sequential analysis first with sulfuric acid leach and sequentially for cyanide leach. For zinc there is a single solubility analysis using acetic acid. The project uses a protocol that includes blanks, standards, and duplicates which make up 12% of each sample shipment.

All statements in this release, other than statements of historical facts, that address future production, reserve potential, continuity of mineralization, exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements. Although the Company believes that the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. The likelihood of future mining at Cobre Grande is subject to a large number of risks and will require achievement of a number of technical, economic and legal objectives, including obtaining necessary mining and construction permits, completion of pre-feasibility and final feasibility studies, preparation of all necessary engineering for pits and processing facilities as well as receipt of significant additional financing to fund these objectives, as well as funding mine construction. Such funding may not be available to the Company on acceptable terms or on any terms at all. There is no known ore at Cobre Grande and there is no assurance that the mineralization at Cobre Grande will ever be classified as ore.
