Capsule Geology

The David minerals property, including the Spark and Joy claims, is located between Morrison and Nakinilerak lakes, 18 kilometres southeast of the community of Fort Babine.

Generally, a granodiorite stock containing phases of quartz monzonite and hornblende biotite feldspar porphyry of the Eocene Babine Intrusions cuts grey, locally graphitic siltstones of the Middle to Upper Jurassic Ashman Formation (Bowser Lake Group).

Locally, stratified intermediate composition tuffs or greywacke and mudstone with minor silicification and some graded sandstones have been identified. These units have been locally strongly fractured and cemented with quartz and/or pyrite.

Pyrite has been identified in six outcrops and chalcopyrite in one.

Work History

In 1969, David Minerals Ltd. contracted Evergreen Exploration to survey claims including Joy and Spark with helicopter-mounted magnetic and electromagnetic equipment (Assessment Report 02103). Results identified two zones of possible porphyry mineralization.

In 1970, Palisade Exploration and Evergreen Exploration completed 56 327.04 line-metres of cut grid and 67 592.448 line-metres of flagged grid as well as a program of geophysical and soil geochemical surveys on the property. Soil samples were taken every 60.96 metres of the B horizon. Soil sampling yielded no significant results. Two magnetic anomalies were identified on line 120 north (Assessment Report 02896).

In 1971, Palisade Exploration tested the southern magnetic anomaly with a diamond drilling program (68.4 metres).
