Montcalm, Ontario

Montcalm

The 11 claim (145 unit, 2,320 hectares) Montcalm property, located 65 km northwest of Timmins, is adjacent to Xstrata Nickel's producing Montcalm mine and covers four kilometres of the interpreted strike extension of the host geology, with only two known historic boreholes within that trend. The most recent ground electromagnetic survey was in 1995 and it detected a number of conductors. INV completed linecutting, ground electromagnetic ("UTEM") and magnetometer surveys in the winter of 2008.

A drill program commenced in late January 2009 and was completed in early March to test a number of UTEM anomalies. Although the original contemplated drill program consisted of testing nine UTEM anomalies, the program was terminated after drilling six anomalies totaling 1,530 metres, as several of the planned drill holes had no readily available water source for drilling purposes due to harsh winter conditions.

INV-09-001 was drilled to a final depth of 206 metres to test a two line UTEM anomaly (anomalies 126 and 129, both ten channel conductors with late time support), trending in a north-south orientation, and parallel to the orientation of the Montcalm orebody. There was no explanation for the conductor in the hole.

INV-09-002 was drilled to a final depth of 233 metres to test a two line UTEM anomaly (anomalies 116 and 118, both nine channel conductors), trending in a north-south orientation. In 2004, Aurora Platinum Corp. ("Aurora") drilled MC-04-04 in a north to south direction to test a conductor at the same location. The hole failed to explain the conductor but intersected thick sequences of gabbroic breccias locally containing ultramafic fragments with minor sulphides. INV-09-002 was drilled from west to east based on the interpretation that the conductor was trending north-south, and therefore, the Aurora hole had run parallel to the target, remaining either in the footwall or hangingwall. The INV conductor was explained by several narrow bands of semi-massive magnetite.

INV-09-003 was drilled to a final depth of 389 metres to test a one line, ten channel conductor, UTEM anomaly 52. Six separate intervals of disseminated to semi-massive sulphide, predominantly pyrrhotite, were intersected, ranging in core length from 6.2 to 17.5 metres. However, the sulphide sections did not carry anomalous base or precious metal values.

INV-09-004 was drilled to a final depth of 325 metres to test a one line, ten channel conductor, UTEM anomaly 103. There was no explanation for the conductor.

INV-09-007 was drilled to a final depth of 209 metres to test a one line, ten channel conductor, UTEM anomaly 149. Minor disseminated gabbro-hosted pyrite may explain the conductor.

INV-09-008 was drilled to a final depth of 167 metres to test a one line, nine channel conductor, UTEM anomaly 148. Minor disseminated pyrite and pyrrhotite may explain the conductor.

Given that there is virtually zero outcrop exposure on the property, exploration must rely almost entirely on geophysics, in particular electromagnetic surveys such as UTEM. Any conductors detected could be indicative of a sulphide body similar to the Montcalm orebody and therefore represent valid exploration targets. There are numerous untested conductors, including the three targets which were not drilled during the 2009 winter program due to the conditions. The untested conductors remain of interest and may be drilled at a later date.
