Capsule Geology

The Stir Stick showing area is dominated by a thick succession of intermediate to felsic volcanic rocks of the Lower Jurassic Telkwa Formation. Dacite and andesite flows, breccias and volcaniclastic rocks as well as small localized areas of basalt are typical. Sedimentary rocks of the Lower Cretaceous Skeena Group occur as a minor constituent of the local property geology.

At the Stir Stick zone, road cuts expose vertical faces of dark-green to greyish-green micro-brecciated and flow banded dacitic lavas. The lavas are broken by a multitude of fractures and small shears, many of which carry minor malachite staining. A shallow dipping fault appears to separate the flow banded unit from the brecciated unit below. Small amounts of chalcopyrite are typically associated with calcite, and occasionally barite, along fractures

A 2 metre trench sample of healed dacitic breccia, locally flow-banded, and containing occasional quartz-chalcopyrite stockworks and rare barite-calcite-chalcopyrite veinlets assayed 0.16 per cent copper (Assessment Report 30454).

WORK HISTORY

The Lund & Thompson property covers a few copper showings that have seen little previous exploration. Two MINFILE occurrences (093L 175 and 093L 176) are recorded on the property and other than the 2011 Aster interpretation received no other work during the 2000s.

The Stir Stick zone was discovered by Dwayne Lund in October, 2003, while investigating the western end of the Shea Creek road where a new logging block and road network had been developed. Several road cuts excavated into bedrock exposed fractured and malachite-stained volcanic rocks and, locally, chalcopyrite and bornite with calcite-barite and quartz in fractures, narrow veins and crude stockwork zones.

The Umbrella zone was discovered by Dwayne Lund, who noted malachite-stained float over several hundred metres in a narrow canyon while descending from Herd Dome Mountain following a hunting expedition in September 2004. Early snow prevented immediate follow-up, but return prospecting trips to the steep drainage corridor in 2005, yielded impressive bedrock mineralization.

In 2008, a limited geological mapping and sampling program was conducted on the Lund & Thompson property for Lowprofile Ventures Ltd. A total of 27 rock samples were collected. The Stir Stick and Umbrella showings were examined and sampled and high copper samples LTSB079 and LTDB046 were collected. A third unnamed showing was discovered in the southeast corner of the tenure but was not properly documented in reports.

In 2011, Lowprofile Ventures Ltd engaged Cal Data Ltd (Ward Kirby, PGeo) to provide an in-depth analysis ASTER (Advanced Spaceborne Thermal Emission and Reflection) and Landsat imaging of the property area signatures for buddingtonite or similar ammoniated minerals show a particular concentration near the northern boundary of the property. These types of signatures are known to mark gold deposits in other districts.

In 2012, 71 soil samples were collected on a small grid along an apparent strike of the Stir Stick zone as well as soil samples along southern and south eastern road accesses.
