The Boomerang property is in the Yeheniko Lake region of northwest B.C. approximately 30 kilometres south-southwest of Telegraph Creek.
The property is within a broad northwest trending belt of Stikine Terrane consisting predominantly of Lower to Middle Jurassic Hazelton Group calc-alkaline volcanic and sedimentary rocks. Two Middle Jurassic tonalite bodies of the Three Sisters Plutonic Suite intrude into the southern edge of the Hazelton Group volcanics. Cretaceous to Paleocene coarse clastic sedimentary rocks occur in the south and western regions. Mid to Late Triassic quartz diorite intrusive rocks fringe the northeast sector of the property, part of a much larger batholith. Several quartz monzonite dikes occur in the Hazelton Group rocks in the northern part of the property.
In 2018, Hawkeye Gold and Diamond Inc. conducted a rock and soil sampling program on the Boomerang Property Assessment Report 37812). Thirty rock samples collected confirmed an east-west trending copper mineralized area (Zone 1) hosted within calc-alkaline Hazelton Group volcanic rocks and quartz monzonite dikes in the north-central part of the property. This zone is characterized by a nearly 4-kilometre-long trend of intermittent propylitic alteration and veined volcanic rocks and the intruding dikes. Mineralization consists of narrow copper-bearing calcite veinlets and fractures. Nine rock samples had copper grades ranging from 0.1 per cent to 1.8 per cent. The zone also showed weakly anomalous molybdenum (18 to 23 parts per million) and moderately to strongly anomalous silver (0.9 to 1.4 grams per tonne). This zone follows the southwest edge of a magnetic high identified as 200 by 3000 metres in the 2016 Geological Survey of Canada aeromagnetic data compilation.
A 0.5 metre sample taken across a fracture zone in mafic volcanics returned 1.56 per cent copper.
A 0.5 metre sample across a potassium feldspar-rich porphyritic dike returned 1.71 per cent copper.
The 2018 soil sampling program, consisting of 402 samples, assessed several areas of calc-alkaline volcanic rocks and overlying clastic sedimentary rocks on the Boomerang Property (Assessment Report 37812). Anomaly A (corresponds to Zone 1): 500 by 2600 metres: 100 to 1225 parts per million Cu; 10 to 12 parts per billion Au; 6 to 13 parts per million Mo. Anomaly B (northwest of Anomaly A): spotty anomalies of 246 to 599 parts per million Cu; 11 to 64 parts per billion Au. Anomaly C: (south region of property) discontinuous anomalies of 51 to 126 parts per billion Au.
Work History
The first recorded work on the property was by Teck Corp. in 1989 and consisted of prospecting, geological mapping, stream sediment and soil sampling (42 soil, 42 stream sediment, 11 moss mat and 50 rock samples). Several anomalous rock samples showed copper values up to 0.727 per cent and gold up to 1.38 grams per tonne (Assessment Report 19267).
In 1990, Teck followed-up the previous work with more soil sampling and a ground magnetometer survey. The 230 soils collected resulted in moderately to strongly anomalous copper and zinc values and few weakly anomalous gold values. The magnetometer survey showed a strong east-west alignment of highs and lows appearing to correspond with quartz diorite intrusions, intrusive dikes and structures (Assessment Report 37812).
