Rockcliff drills copper-zinc at Rail property

Rockcliff Resources (RCR-V) has completed the first phase of drilling at the Rail base metal property, part of its Snow Lake project in central Manitoba. A total of 5,870 metres in 27 holes have been completed.

Rockcliff highlights assay results from four holes: hole 25 returned 5.5 metres grading 2.14% copper and 2.09% zinc from a depth of 137 metres, including 1.8 metres of 5.16% copper and 4.91% zinc; hole 27 cut 8.2 metres of 1.36% copper and 0.08% zinc from 159 metres, including 3.2 metres of 2.19% copper; hole 24 intersected 3.2 metres of 1.13% copper and 1.03% zinc from 89 metres, including 0.3 metre of 3.7% copper and 5.36% zinc; and hole 26 returned 1.4 metres grading 1% copper and 0.15% zinc. Gold grades in the four holes range from 0.02 to 0.88 gram gold per tonne.

The drilling has intersected potentially continuous volcanogenic massive sulphide (VMS) -style mineralization across a northsouth strike length of over 500 metres and to a vertical depth of 300 metres. Geophysical testing indicates that mineralization is open along strike and at depth.

The VMS mineralization is associated with juvenile arc rocks, the same type of rocks that host all of the mined VMS deposits in Manitoba’s Flin Flon and Snow Lake camps.

The Rail property’s mineralization consists of stringers and massive sulphide lenses of pyrite, pyrrhotite, chalcopyrite and sphalerite.

The mineralization is associated with a 5-km-long conductive horizon hosting a pervasive, highly altered juvenile arc rock package. Rockcliff’s drilling has intersected VMS-style mineralization within and beyond the limits of the historical deposit.

The historical Rail VMS deposit averages 1.6 metres wide, with a strike length of about 300 metres and a vertical depth of 150 metres. Rockcliff says its drilling suggests that the deposit is more extensive than previously interpreted, and that additional drilling will be needed to define the limits of the deposit and surrounding VMS mineralization. Additional drilling in 2008 will focus on further delineation.

Rockcliff can earn a 100% interest in the Rail property from Hud-Bay Minerals (HBM-T). If Rockcliff earns its interest, HudBay will receive a 2% net smelter return royalty, and has the right to back in to a 65% interest.

On April 7 Rockcliff announced a proposed private placement of $5 million, comprising up to 5.7 million flow-through shares at 70, and up to 1.5 million units at 65.

Each unit consists of one share and half a warrant. Each whole warrant entitles the holder to buy one share at 95 for 24 months.
