In March of 2007, Rockcliff began its acquisition process and
eventually acquired a significant, “district size” land package
in the Snow Lake area. Our Snow Lake VMS Project now covers over
1,800 square kilometres of favorable, prospective geology to
host VMS style deposits located within the Flin Flon Greenstone
Belt, Manitoba. The belt is one of the most prolific and the
largest Proterozoic VMS district in the world. We completed
property deals with HudBay Minerals and a prospecting syndicate,
acquired Mineral Exploration Licenses (MEL) from the Province of
Manitoba and staked crown lands. Rockcliff is presently the
second largest landholder in the belt behind HudBay Minerals.
Our project presently hosts five historical (non NI 43-101
compliant) VMS deposits rich in copper, zinc, gold and silver
(Table 1).

In November 2007, Rockcliff completed an
independent NI 43-101 Technical Report on the Snow Lake VMS
Project. This report recommended $9.7M of exploration to be
conducted on the project in 2008. It also concluded that the
deposits have excellent potential to expand beyond their
historical resources and that all of the deposits are open along
strike and at depth. Furthermore, the report concluded that
excellent potential to discover additional VMS-type targets
exists throughout the project area. The recommended exploration
program for 2008 included 10,000 line kilometres of airborne
geophysics, deep penetrating EM geophysical surveys over the
historical deposits, and 35,000 metres of resource definition
and reconnaissance diamond drilling.
Additional areas with underexplored VMS
potential are located under a thin (<100 metres) cover of
sedimentary rocks located in the southern part of the project
area. This area is known to contain a large volume of “juvenile
arc rocks” which are the same type of rocks that host all of the
VMS mines in the belt north of the sedimentary cover. Two of
Rockcliff’s present deposits (Kof and Sylvia) and the former
Spruce Point Mine are associated with juvenile arc rocks under
this sedimentary cover. This fact provides significant evidence
of the untapped potential for additional VMS discoveries in this
underexplored area below the cover.
Also, VMS potential occurs on the properties
within the project area located in very close proximity to
HudBay Minerals recently discovered Lalor Lake VMS Deposit. It
is a world class deposit estimated to contain 20 million tonnes
of high grade zinc, copper and precious metals. Rockcliff has
acquired by staking two properties (Squall and Tramping Lake)
which are located to within 6 km north and south of the deposit.
Both properties host underexplored juvenile arc rocks and remain
excellent properties with VMS potential. By
April 2008, Rockcliff completed its first phase exploration
program at the Snow lake VMS Project. It included:
-
9,633 line km of high resolution
airborne magnetic and VTEM surveys covering 70% of the
project area
-
Surface, deep penetrating geophysical
pulse EM surveys over two (Rail, Reed)VMS deposits
-
Drilled 5,871m in 27 holes on the Rail
Property
-
Drilled 1,651m in 7 holes on the Kof
Property
-
Drilled 794m in 4 holes on the Sylvia

Interpretation and Prioritization of VTEM
Targets:
To date, the ongoing geophysical prioritization program of the
VTEM Survey has been completed on the Lon Property representing
651 line km of the 9,633 line km survey. The VTEM survey was
completed by Geotech Ltd of Aurora, Ontario. At Lon, it has
identified a minimum of sixteen high priority airborne targets.
The high priority airborne targets are all associated with
juvenile arc assemblage rocks, the same type of rocks that host
all of the VMS (copper, zinc, gold and silver) mines in the Flin
Flon and Snow Lake camps. Of importance is the fact that one of
the sixteen targets identified in the survey covers the
historical Lon Cu-Zn Deposit and the remaining targets all have
similar geophysical characteristics as the Lon Deposit
geophysical characteristics.
First Phase Drill Results
The Company’s first phase drill program has now been completed
in which 38 drill holes totaling 8,300m tested VMS (copper,
zinc, gold and silver) mineralization on three properties at the
Snow Lake VMS Project. Twenty-seven holes were completed at the
Rail Property, seven holes at the Kof Property and four holes at
the Sylvia Property. A total of 33 drill holes intersected
significant VMS mineralization. All VMS zones intersected in the
drilling are open along strike and at depth and are worthy of
additional drilling.
Some of the highlights from the first phase
drill program are outlined below. Rail
