Linear Metals Intersects 96 metres of 1.76% Copper at Cobre Grande Project, Oaxaca, Mexico

TORONTO, ONTARIO--(Marketwire - Oct. 11, 2007) - Linear Metals Corporation (TSX VENTURE:LRM) is pleased to report that it continues to intersect significant copper-molybdenum-zinc mineralization at its Cobre Grande project, located in Oaxaca, Mexico. Highlights from the most recent drill results are:

- CG-39: 46.9 metres of 3.62% zinc, 0.09% copper, 0.022% molybdenum and 8.2 grams per tonne silver;

-- including 28.0 metres of 5.20% zinc, 0.11% copper, 0.010% molybdenum and 8.7 grams per tonne silver;

- CG-40B: 96.31 metres of 1.76% copper, 0.070% molybdenum, 0.55% zinc and 59.8 grams per tonne silver;

-- including 26 metres of 3.37% copper, 0.128% molybdenum, 0.60% zinc and 119.7 grams per tonne silver; and

- CG-41: 105.5 meters of 1.01% copper, 0.033% molybdenum and 12.1 grams per tonne silver.

The current exploration program is multi-faceted with drilling augmented by a detailed soil sampling program, a 20-line kilometre IP survey, rock chip sampling of new road cuts, and sampling for the first phase of a metallurgical testing program. Assay results from drill holes CG-38 to CG-41 have been received and the results from an additional nine holes are pending. Drill-holes CG-37, twinned by CG-38, and CG-40, twinned by CG-40B, were lost at 68 metres and 16 metres, respectively, before reaching the mineralized skarn target.

Results for holes CG-38 through CG-41 are summarized in the table below (a drill hole location map is available on the Company's website at

North Zone

Drill-hole CG-40B was drilled in the North Zone from the same site as hole CG-40 which was lost in bad ground short of target. Hole CG-40B cut 96.31 metres of skarn averaging 1.76% copper, 0.070% molybdenum, 0.55% zinc and 59.8 grams per tonne silver, including a 26 metre high grade zone of 3.37% copper, 0.128% molybdenum, 0.60% zinc and 119.7 grams per tonne silver. The final 1.7 metre sample from CG-40B returned 0.76% copper, 0.041% molybdenum, and 36.0 grams per tonne silver before it was also lost in bad ground. Holes in the current phase of the drill program, initiated August 1, 2007, are being drilled from east to west across the zone in an effort to provide a better estimate of thickness.

The CG-40B intersection parallels the 55.63 metre intersection previously reported in CG-32 that returned 1.53% copper, 1.41% zinc, 0.031% molybdenum, and 54.0 grams per tonne silver and while comparable in grade, was over 40 metres thicker, indicating the zone thickens with depth (the trace of CG-40B is 100 metres below that of CG-32).

South Zone

Hole CG-41 is the first hole of a series of west directed angle holes which are planned to test the width and strike extent of the steeply east dipping South Zone skarn in preparation for the resource estimate. The hole was successful in cutting 105.5 metres of mineralized skarn grading 1.01% copper, 0.033% molybdenum and 12.1 grams per tonne silver. Furthermore, the hole cut 58 metres of 0.091% molybdenum beneath the copper zone which, along with the significant molybdenum intercept in hole CG-40B, highlights the potential of Cobre Grande to host a significant molybdenum resource.

In addition to results from the current phase of the program in the South Zone, Linear is pleased to report on the final two holes of the previous 4,000 metre phase of the program completed in June 2007. Holes CG-38 and CG-39 were drilled as offsets to CG-36 (132 metres of 1.62% copper, 0.01% molybdenum, 0.51% zinc and 26.0 grams per tonne silver) located at the north end of the South Zone. Hole CG-38, an east directed hole, collared 80 metres northeast of CG-36, returned 68.4 metres of 0.37% copper, 0.011% molybdenum, 0.14% zinc and 12.6 grams per tonne silver and has extended the South Zone to the north. Hole CG-39, a northeast directed hole, collared 90 metres southeast of CG-36, failed to encounter a substantial copper zone as it appears to have been collared too far east to cut the east side of the north-south trending zone of copper mineralization in skarn. However, with 28 metres of 5.20% zinc, hole CG-39 has produced one of the best zinc intercepts to date at Cobre Grande. This intercept combined with previous zinc intercepts in hole CG-08, located 100 metres to the north (26 metres of 1.50% zinc and a second intercept of 36 metres of 2.09%), and hole CG-09, located 100 metres to the south (150 metres of 2.06% zinc, 0.22% copper and 15.0 grams per tonne silver) are starting to define a significant zinc zone along the eastern edge of the South Zone skarn.

IP Survey

The results of a 20 line kilometre IP survey, recently completed by Pacific Geophysics of Vancouver, B.C., indicate the South Zone sulfide bearing skarn could extend south to 1900N, a potential strike length of 1,000 metres - double what has been delineated by prior drill programs (2400N to 2900N - see website for map). Drilling is now progressing south from hole CG-41 to test the length of this anomaly. The results of the IP survey also identified several new significant targets that will be tested by future drilling.

Grant Ewing, Linear Metals President states, "Linear Metals continues to intersect significant high-grade mineralization on the Cobre Grande property. This is an exciting time for Linear with two major projects, KM 61 and Cobre Grande, returning impressive results. Linear has made two significant mineral discoveries and work is in progress to complete NI 43-101 compliant resource estimates on each of the projects over the coming months. With a strong balance sheet, experienced technical staff, and an attractive equity structure, we look forward to aggressively advancing both projects for the benefit of our shareholders."

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.

This press release was prepared under the supervision of Linear Metals' Vice President of Exploration, Dr. Robert Page, P. Geo., who is a Qualified Person as defined under National Instrument 43-101. Dr. Page has reviewed the scientific and technical information in this press release.

This release includes certain statements that may be deemed "forward-looking statements". 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.
