Linear Metals announces new discovery

Linear Metals Corporation has reported a new discovery on the Northwest Skarn target, located 600 metres west of the Main Zone, at its Cobre Grande Project, in Oaxaca, Mexico.

The recently announced 49.8 million tonne resource estimate from the Cobre Grande Project did not include any mineralization from the Northwest Skarn, which now represents a priority target for significant expansion of the Cobre Grande Project’s initial resource.

The second hole, in this previously undrilled target, has produced the following discovery intercept and highlights the excellent exploration potential remaining to be tested at Cobre Grande:

• CG-68: 228 metres of 0.91% copper equivalent starting at 29 metres.

Linear is also pleased to announce that it has received assays from the bottom of hole CG-60 which include:

• CG-60: 72 metres of 0.073% molybdenum

Added to the previously reported intercept of the hole the new assays document the longest molybdenum-rich intercept to date on the property of 332 metres of 0.058% molybdenum starting at 4 metres depth.

The copper equivalent calculations also take into account assumptions regarding concentrate properties, smelter charges, and payable percentages as well asmetallurgical recoveries (zinc will not be recovered in any of the mineralization types encountered in this hole) which vary between sub-zones, resulting in different copper equivalent formulas for each zone as follows:

1. Composite weighted average copper equivalent from intervals below.

2. Copper sulphide skarn copper equivalent = Cu%+Mo%($233.01/$39.25) + Ag g/t($0.31/$39.25);

3. Molybdenum sulphide stockwork = Mo%($349.65 /$39.25); Pending further metallurgical testing, copper and silver are assumed non-recoverable in the Molybdenum Stockwork sub-zone.

4. Partially oxidized copper and molybdenum zones copper equivalent = Cu%+Mo%($150.98/$37.84) + Ag g/t($0.27/$37.84)

Hole CG-68 is one of the longest continuously mineralized intercepts to date at Cobre Grande.

This hole, a -70° east directed angle hole, started in an oxide zone of mineralized garnet skarn and entered the sulphide zone beginning at 29 metres.

It then continued through increasingly altered and quartz veined skarn until passing through a major fault at 257 metres and into weakly altered footwall rocks.

This intercept appears to be in a skarn that is, in terms of sulphide mineralogy and skarn alteration, similar to the copper bearing skarn of the Main Zone, 600 metres to the east.

Based on this interpretation, hole CG-68 may have drilled down-dip a steeply east dipping body with a true thickness, by analogy to the Main Zone, of approximately 20 to 100 metres.

Additional drilling will be required to better understand the orientation of the geology in this new discovery zone and confirm the true thickness.
