 - Copper Extension Project

 

Location and Property Description
The Copper Extension Project is situated immediately south of both the Copperman and Copper project areas approximately 45 km south and east of the Town of Snow Lake where active mining and milling of base metal massive sulphide-type deposits and precious metals has been ongoing for decades. Access to the property is by a variety of logging and drill roads and trails. The Copper Extension Project consists of one mineral exploration license (MEL 264A) and 6 claims with a total area of 8,157 hectares. The property is 100% owned by VMS Ventures.

History of Exploration
The project area consists of 2 mineral exploration licenses that are characterized by extensive organic cover that overlies Ordovician dolomite. This dolomite veneer obscures the prospective volcanic and sedimentary rocks of the Flin Flon-Snow Lake greenstone belt. Accordingly, traditional bedrock geological mapping and prospecting are useless and indirect methods of exploration based on geophysics and geochemistry are required.
The project area straddles the same belt of sub-Paleozoic volcanic rocks and associated sedimentary rocks that host the Copperman copper-zinc deposit and underlay the Copper Project. The general area has been explored primarily by airborne geophysical surveys and some ground geophysical surveys and diamond drilling.

In 1985, Noranda Exploration Company, Limited undertook a Horizontal Loop electromagnetic geophysical survey and defined multiple conductive zones, some with strike lengths of up to 2.25 km. A total of 17 bedrock conductors were defined and recommended for further exploration. In 1986 Noranda with joint venture partner Manitoba Mineral Resources Ltd. undertook ground electromagnetic and magnetometer surveys and drilled a total of 1423 metres in 11 holes. Results indicated graphitic conductive zones with up to 60% pyrite and lesser pyrrhotite were present. Assays indicated base and precious metal contents were low.

In 1990 Quest Canada Resources flew Questor airborne geophysics including electromagnetic and magnetic surveys and documented multiple conductive zones. The Snow Lake joint venture, consisting of Teck Explorations Ltd., Consolidated Samarkand Resources Inc. and T.S.A. Explorations Ltd., established grids over Questor airborne electromagnetic and magnetic anomalies and followed up with DEEPEM and magnetic surveys in 1991. The best conductive responses were targeted with nine diamond drill holes. Previous drilling had intersected mafic flows and intrusions, sulphide-rich graphitic argillite, mixed mafic and felsic flows and tuff with lenses of graphitic argillite and metasedimentary rocks with graphitic argillite and pyrrhotite-bearing iron formation. The Snow Lake joint venture concentrated drilling on the sequence of mafic to felsic flows and tuff and intersected pyrite-pyrrhotite-rich graphitic argillite although locally the host rock units were strongly altered to a combination of chlorite and sericite. Numerous additional conductors were never tested.

Between 1993 and 1995 Hudson Bay Exploration and Development Co. Ltd. undertook airborne electromagnetic and magnetic using their SPECTRUM system and defined multiple bedrock conductors.

Philosophy of VMS Ventures Exploration
At the Copper Extension Project the recognition of the same belt of volcanic and sedimentary rocks that host the Copperman copper-zinc massive sulphide deposit, underlay the Copper Project and the extension of this geology on to the Copper Extension Project provides an excellent case for follow-up exploration. The presence of the Sylvia and Kof Zones copper-zinc mineralization within the southern end of the greenstone belt is indicative of potential for the discovery of additional VMS-type mineralized zones. Subsequent to historic exploration data review an integrated geological-geophysical-geochemical exploration program to assess the Copper Extension Project area for additional base metal massive sulphide-type mineralization and associated precious metal mineralization was initiated. Due to dolomite cover the initial phase of exploration on this project will consist of geophysical and geochemical targeting with diamond drill follow-up.

Geology
The area of the Copper Extension is characterized by variably altered and mineralized volcanic rocks overlain by a veneer of Ordovician dolomite. These Proterozoic volcanic rocks, which also host base metal massive sulphide deposits in the Snow Lake area, continue southwards from the Copperman and Copper project areas.

The sub-Paleozoic southwest-trending greenstone belt that underpins the Copper Extension Project consists primarily of juvenile arc volcanic rocks including mafic and felsic volcanic and volcaniclastic rocks, greywacke and derived gneiss. This sequence is intruded by a compositionally diverse suite of lithologies including gabbro, diorite, quartz diorite, leucocratic granodiorite to tonalite, granite and syenite to monzonite. This sequence is flanked to the east and in fault contact with graphitic greywacke and derived gneisses and migmatite that are intruded by monzodiorite to quartz monzonite. 

Geophysics
VMS Ventures Inc. conducted an airborne geophysical survey over the property in early 2007 using GEOTECH’s VTEM system. Numerous well-defined conductors were identified. Some of the conductors were drilled previously and found to contain pyrite and graphite rock units, but others have not been tested to date. These anomalous VTEM responses indicate the presence of bedrock-hosted conductive metals such as copper- and zinc-bearing sulphide with associated gold and silver as well as graphite and the iron sulphide minerals pyrite and pyrrhotite. Of importance is the recognition of VMS-style alteration associated with some of the undrilled conductors. Follow-up geochemical surveys have been initiated and VTEM anomalies with coincident geochemical survey results become targets for follow-up drill testing.

Geochemistry
Phase 1 partial extraction soil geochemical surveys were completed in 2008 and 2009 resulting in the detection of several areas of base and precious metal anomalous responses on the property. These responses were coincident with individual airborne VTEM responses. More detailed grid-based soil geochemical surveys were initiated in early 2010 to pinpoint coincident multi-element base and precious metal anomalies and VTEM geophysical responses. These targets will help to focus diamond drilling planned in 2010.

Deposit Types
Base metal massive sulphide-type mineralization hosted within a sequence of altered volcanic rocks and chemical sedimentary rocks or exhalites are indicative of volcanogenic massive sulphide-type base metal mineralization (“VMS”). This deposit type is representative of Flin Flon – Snow Lake VMS-type deposits and includes the Discovery Zone at Reed Lake. This type of mineralization is the target at the Copper Extension Project.
