The claims are underlain by several formations, the oldest being Lower Jurassic Hazelton Group volcanics (Telkwa Formation), comprised of red, green to maroon andesitic tuffs and flows. To the west, the Telkwa rocks are overlain by Upper Cretaceous Francois Lake Group, Tip Top Hill Formation volcanics comprised of biotite-hornblende andesite and andesitic to dacitic flows and breccia. These rocks are intruded by a Late Cretaceous Bulkley Intrusive comprised of quartz monzonite to porphyritic granodiorite and associated feldspar porphyry dikes (Bulletin 78, Figure 1).
To the east, the Telkwa rocks are overlain by Eocene Goosly Lake volcanic sills and trachytic flows of the Francois Lake Group. These are overlain by the Houston Member of the Eocene Buck Creek volcanics comprised of massive, vesicular to aphanitic andesite, dacite flows, breccia and minor basalt. To the south, near Parrott Lake these rocks are intruded by an Eocene Goosly Lake syeno-monzonite plug.
Locally, the volcanics were mapped as Late Cretaceous Tip Top Hill andesitic, dacitic and rhyolitic flows and pyroclastics. The most common outcrop is red andesitic tuff which is sheared, bleached as well as carbonate altered and silicified hosting 0.1 per cent barite. Other rocks include rhyolitic to dacitic flows with a white, dense groundmass some hosting quartz eyes. Some of these rocks are brecciated and are crosscut by quartz veinlets hosting pyrite.
A syeno-monzonite plug or a northwest trending Tertiary dike is in contact with the rhyolitic rocks.
Mineralization consists of low grade disseminated galena, sphalerite and pyrite in a calcareous arkose(?) on the east side of the claims. Also, weak chalcopyrite and pyrite occurs in quartz veinlets in the rhyolitic and andesitic flows. In 1984, a sample of the mineralized andesite assayed 39.6 grams per tonne silver and 0.277 per cent zinc (Assessment Report 12753).
In 2012, Quartz Mountain Resources Ltd. conducted an airborne magnetometer survey on the area northwest of Parrott Lakes. The results are reported to reflect a large oval-shaped 12 km by 6 km caldera-like feature, with several internal magnetic highs that may reflect intrusive centres.
In 2013, Quartz Mountain Resources Ltd, as part of a much larger program, carried out reconnaissance exploration on the current south-central part of the Property. Work comprised an induced polarization (IP) survey, two reconnaissance geochemical soil lines and scattered rock sampling. The IP survey was run in part over the southern portion of a caldera-like magnetic response from the 2012 airborne survey. The results show zones of weak to moderate chargeability with high resistivity overlain by low resistivity, indicative of thick overburden.
