Linear Metals Extends Northern Copper-Silver Skarn Zone at Cobre Grande Project, Oaxaca, Mexico

HALIFAX, NOVA SCOTIA--(CCNMatthews - April 10, 2007) - Linear Metals Corporation (TSX VENTURE:LRM) is pleased to provide an update on activities at its Cobre Grande Project, located 60 kilometres west of Oaxaca, Mexico. The results from drill holes CG-30 and CG-32 have successfully expanded the northern copper skarn zone intersected in CG-28, previously reported, which contained 1.0% copper and 23.2 grams per tonne silver over 270.7 metres. Drill hole CG-29, drilled in the southern zone of the deposit, also cut the first porphyry copper style mineralization encountered at Cobre Grande including a 50.55 metre zone with 0.62% Cu and 18.4 grams per tonne silver.

A table of recent assay results from drilling at Cobre Grande is included with this press release, and a Drill Hole Location Map is posted on Linear Metals' website at www.linearmetals.com.

Northern Copper Skarn Zone

Hole CG-30, collared 40 metres north of hole CG-28, was drilled at an azimuth of 90 degrees and an inclination of -65 degrees. This hole expanded the zone of mineralization with an intersection of 91.44 metres of 0.80% copper and 23.2 grams per tonne silver, starting at 172.21 metres, which correlates with the intersection in hole CG-28. Several additional mineralized zones were also intersected including 12.19 metres of oxidized skarn mineralization that assayed 1.56% copper, 34.6 grams per tonne silver, 1.56% zinc and 0.042% molybdenum starting at 19.81 metres.

Hole CG-32, collared 28 metres southeast of CG-28, between holes CG-28 and CG-01, was drilled at an azimuth of 270 degrees and an inclination -70 degrees. Hole CG-32 was drilled in the opposite direction to better understand the geometry of the mineralized interval intersected in CG-28. Hole CG-32 intersected 55.63 metres of 1.53% copper, 53.8 grams per tonne silver, 1.49% zinc and 0.037% molybdenum, starting at 18.12 metres. This intercept, along with those of holes CG-28 and CG-30, includes a significant thickness of oxidized mineralization that could be amenable to low cost SXEW processing.

Hole CG-31, drilled from an existing road, located 130 metres west of hole CG-28, was also an east directed hole, but was collared at an elevation 100 metres lower than hole CG-28. This hole appears to have drilled underneath the copper skarn, cutting intensely quartz stockworked porphyry and hornfels with 104 metres of 0.024% molybdenum.

Southern Zone

Hole CG-29 was drilled in the southern zone, 100 metres east of hole CG-24. This -65 degrees hole drilled to the east (080 degrees) targeted the eastward extension of the well developed stockwork previously intersected in CG-24, which assayed 0.88% Cu over 148 metres. Hole CG-29 successfully expanded mineralization to the east, intersecting 50.55 metres of 0.62% copper and 18.4 grams per tonne silver, starting at 224.85 metres. Most importantly, however, this is the first porphyry copper style mineralization encountered at Cobre Grande. Hole CG-29 also had a 30.49 metre intercept of polymetallic mineralized skarn starting at 90.85 metres grading 0.40% copper, 1.58% zinc and 30.4 grams per tonne silver.

The significant copper-silver mineralization identified in holes CG-28, 30 and 32 remains open to the north and north-west. New road construction is required to access these areas for drilling and the Company has applied for the necessary environmental permits which are expected to be received in the coming weeks. In the short term, drilling at Cobre Grande has been reduced to one drill rig focused on delineation drilling in the southern zone of the deposit.

Linear has also initiated a property wide reconnaissance program on its 6200 hectare Cobre Grande property. Regional stream sediment sampling, soil sampling and geologic mapping have begun and a high resolution airborne magnetics and EM survey has been contracted with Aeroquest International and is expected to be flown over the entire property by the end of May.

Robert Page, V.P. Exploration commented that, "We are excited about the high grade Cu-Zn-Ag skarn in the northern zone of the deposit and will continue to aggressively track the mineralization to the north and northwest as soon as we receive the permit to complete the necessary road construction. In the meantime, we are fortunate to be able to advance the project towards a 43-101 compliant resource by having access to drill sites in the southern zone. In addition, we are particularly pleased with the copper porphyry cut in CG-29 which potentially opens up a whole new target type within the Cobre Grande project. Previously holes have cut intense quartz vein stockworks with low copper values. In contrast, in hole CG-29 we see a long zone of porphyry copper style alteration and mineralization in porphyry including a 50.55 metre zone with 0.62% Cu and 18.4 grams per tonne silver. This intercept suggests the potential for more extensive porphyry mineralization within this area and elsewhere on the larger Cobre Grande concession which we are just beginning to explore."

This press release was prepared under the supervision of Robert Page, P. Geo. who is the Qualified Person for the project. The Cobre Grande Project ships samples 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. Samples from CG-29 were analyzed for gold by fire assay with Atomic Absorption (AA) finish. Copper, zinc, molybdenum, silver, lead and 31 other elements were determined by aqua regia acid digestion, followed by ICP finish. Starting with drill hole CG-30 the protocol for analyzing core was changed. 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.
