Bridgeland’s 100% owned, contiguous 2,108 hectare Tower Property is located 10 km. south of Sayward, between the White and Salmon Rivers. The Property is underlain primarily by volcanic rocks of the Triassic Karmutsen Formation, and locally by sedimentary rocks of the Triassic Parson Bay Formation. These are intruded from the south by a large stock and surrounding halo of narrow sills and dikes of Jurassic Island Plutonic Suite granodiorite and diorite.   The Property covers a copper-silver breccia vein showing (BC MINFILE 092K167 – North Memekay), discovered in 2005. The showing consists of three clusters of north-south trending quartz-epidote-sulphide veins exposed in logging roads over a 1.2 km distance along the north side of a small mountain at approximately 600 m. elevation. The area of Jurassic intrusions near the Triassic/Jurassic boundary is considered an ideal geological setting on Vancouver Island for Porphyry Copper-Molybdenum-Gold deposits, and related Copper, Iron, Lead-Zinc and Gold Skarn deposits.


In early 2006, a single 130 m. diamond drill was completed to test a north-south trending, copper-silver-gold bearing quartz sulphide vein occurrence discovered by Mr. Dan Berkshire in a logging road cut near the centre of cell mineral tenure 551391. The author logged and sampled the core from the hole, with intercepts achieved as follows:

  • 42.4 to 43.9 – 1.5 m. @ 0.106% copper in silicified, epidotic, locally hematitic and brecciated mafic volcanics with 35% quartz-epidote-actinolite-sulphide zones
  • 72.4 to 77.0 – 4.6 m. @ 0.438% copper in silicified, magnetitic mafic volcanics with 35% quartz-epidote-sulphide stockwork zones
  • 114.3 to 116.6 – 2.3 m. @ 0.151% copper in silicified, epidotic porphyritic mafic volcanics with 20% quartz-epidote-sulphide stringers and seams


During 2007, Auracle Geospatial Science Inc. completed a remote sensing spectral analysis program over and surrounding cell mineral tenure 551391. Four areas with alteration mineral signatures were identified all surrounding the granodiorite stock intruding from the southeast corner of the Tower Property, two of which are located on the property, and two immediately east of the property. The largest area of alteration mineral signature surrounds the three clusters of the North Memekay showing; and the next largest is located along a ridge on the southwest portion of the property.


During 2010, the author supervised and conducted a field exploration program on the Tower Property, consisting initially of property wide prospecting and rock and stream moss mat sampling, followed concurrently by GPS controlled, grid-based soil sampling and geological mapping over a 2 by 1 km area surrounding the North Memekay showing. Rock geochemistry highlights from seven samples taken at the three clusters of narrow (0.05 to 1 m. thick) quartz-epidote-sulphides veins (Tower East, Tower Central and Tower West) consist of elevated values up to 7.24 ppm Ag, 19.3 ppm As, 110 ppm Ba, 149 ppm Co, 5.05% Cu, 0.12 ppm Hg, 32.1 ppm Se, 0.34 ppm Te and 758 ppm Zn. Soil geochemistry highlights consist of five clusters of elevated multi-station and multi-element values in at least one target (Cu, Mo, Au) and/or indicator (Ba, Co, Pb) element, identified as anomalies. Stream moss mat geochemistry highlights consist of 9 samples in five areas with elevated values in target (Au, Mo) or indicator (Co, Hg, Pb, Zn) elements, identified as anomalies (BC ARIS Report 31811). Also during 2010, Aeroquest completed 309 line-km of combined magnetic, electromagnetic and radiometric airborne geophysics over all the claims of the Tower Property (BC ARIS Report 32164).


The results of the field exploration program and the airborne geophysical surveys from 2010 have yet to be integrated, which is recommended, along with inversion and modeling of the aeromagnetic data. Recommended follow-up ground work includes extending the soil geochemistry and geological mapping grid to cover three soil anomaly clusters extending beyond the area of the 2010 grid. Prospecting and detailed stream moss mat sampling are recommended for the area of the other two soil anomalies, and for the five areas of stream moss mat anomalies. The 2006 drill intercepts clearly warrant follow-up drilling to determine extent and continuity of copper mineralization.


In summary, the Tower Property hosts a copper-silver breccia vein showing and surrounding alteration signatures in a geological setting appropriate for hosting porphyry copper-molybdenum mineralization. The Property requires additional focused exploration work surrounding the North Memekay showing, plus continued reconnaissance scale exploration. An exploration budget of $400,000 has been proposed, which includes 1500 metres of diamond drilling.
