The Lloyd-Nordik property is located approximately 57 kilometres northeast of Williams Lake and adjoins the Mount Polley property (093A 008) on the north and east. The occurrence is in the Quesnel Trough, a 30 kilometre wide, northwest trending, Mesozoic volcanic-sedimentary belt of regional extent that is fault bounded to the east by rocks of the Barkerville and Slide Mountain terranes, and to the west by Paleozoic rocks of the Cache Creek Terrane.
The current phase of exploration began in 1993 and focused mainly on a gold-bearing breccia 1.5 kilometres north of the Mount Polley pit location, called the Lloyd 2 zone. The property was previously explored by Big Valley Resources in the mid-1980s. Samples, at this time, assayed up to 2.03 grams per tonne gold, 8.94 grams per tonne silver and 1.49 per cent copper (Property File - Chevron File - Poloni, J., 1985). During the mid-1970s the flat-laying area immediately northwest of Mount Polley and stretching nearly to the Quesnel River, bounded by Morehead and Little lakes, was held as the Train claims by Quintana Minerals. Soil geochemical sampling encountered three areas containing 200 to 400 parts per million copper as chalcopyrite and widespread mineralized float boulders containing up to 1.1 per cent copper (Property File Placer Dome Wolfhard, M.R., 1977).
Mineralization occurs on the northern margin of the Mount Polley stock, a high-level alkalic intrusion that, locally, has imparted intense potassium feldspar flooding in the Upper Triassic Nicola Group rocks which it cuts.
The Lloyd 2 mineralized breccia zone has a minimum strike length of 250 metres along its northeast trend and appears to dip steeply to the northwest. The mineralized zone is composed of several lenses that appear to coalesce at the north end of the zone and diverge to the south; they are associated with porphyritic dikes and sills. Mineralization is concentrated in intensely potassium feldspar altered volcanic and dioritic to monzonitic intrusive rocks near intrusive contacts. It is open along strike at both ends. The breccia is composed of angular clasts of salmon coloured potassium feldspar-flooded volcanic and intrusive lithologies healed by a magnetite>>chalcopyrite>pyrite matrix. There is generally a 1:1 relationship between gold and copper grades, but a narrow, high grade gold zone, that averaged 13.45 grams per tonne gold and 0.02 per cent copper over two metres, was intersected during last years drilling and will be tested again early this year (R. Lane, personal communication, 1996).
Preliminary resource estimates for the Lloyd 2 target carried out by Montgomery Consultants Ltd. are as follows (George Cross News Letter No. 60 (March 25), 1996):
--------------------------------------------------------------- Tonnes Cu (%) Au (g/t) Cu cutoff (%) 7,190,000 0.310 0.243 0.10 4,950,000 0.396 0.319 0.15 3,920,000 0.455 0.359 0.20 2,930,000 0.531 0.401 0.25 --------------------------------------------------------------- |
During 1997, Big Valley Resources Inc. conducted diamond drilling on the Lloyd 2 deposit and other zones on its Lloyd-Nordik property. The Lloyd 2 zone (now known as the Boundary zone) mineralization consists of pyrite and chalcopyrite in a monzonitic breccia healed with magnetite. The Boundary zone within the Lloyd 2 claim consists of generally two zones of copper mineralization each a few metres to over 30 metres in thickness and which are interpreted to dip to the west. While most of the mineralization is within hydrothermally brecciated monzonite, minor disseminated chalcopyrite is recognized in nonbrecciated to only mildly “crackle” brecciated monzonite. Mineralization has not been recognized within the overlying volcaniclastic breccia unit. Similar mineralization occurs at the Road showing at Mount Polley, immediately to the east. In March 1996, the company reported a preliminary resource estimate for the Lloyd 2 deposit of 7,190,000 tonnes grading 0.31 per cent copper and 0.243 gram per tonne gold (Information Circular 1998-1, page 25). An indicated resource is reported as 2.5 million tonnes grading 0.55 per cent copper and 0.39 gram per tonne gold, at a cutoff grade of 0.20 per cent copper (Exploration in BC 1996, page C10). A resurvey of the Lloyd 2 claim boundary indicated that about half of its resource lay within an adjoining claim that is held by Mount Polley Mines Ltd. (Assessment Report 29118).
During November 2000, Big Valley Resources Inc. completed four diamond drillholes on the Lloyd 2 mineral claim.
In 2003, 289 soil samples were collected from a geochemical survey on the eastern part of the Lloyd 2 claim on behalf of owners/operators Glengarry Developments Inc. and Quantum Speed Internet Products Inc.
In 2006, approximately 27 line-kilometres of induced polarization/magnetometer surveying and 5283.9 metres of diamond drilling in 25 drillholes were completed by operator Valley High Ventures Ltd.
Between 2006 and 2008, Imperial Metals Corp. carried out yearly drill programs on the Boundary zone with 22 holes (5417 metres) in 2006, 14 holes (4511 metres) in 2007, and 20 holes (5260 metres) in 2008.
In 2009, Imperial Metals Corp. optioned the entire Boundary zone from Valley High Ventures Ltd. and completed a seven-hole drill program. Highlights of this program include drillhole ND09-96, which returned 7.5 metres grading 0.54 per cent copper (Assessment Report 31472).
In 2011, Imperial Metals Corp. conducted underground diamond drilling on the Boundary zone, which was successful in delineating a block of breccia-hosted copper/gold mineralization. Highlights of the program include drillhole NDU11-189, which returned 35 metres grading 4.8 per cent copper, 2.76 grams per tonne gold and 71.06 grams per tonne silver (Press Release, Imperial Metals Corp., August 23, 2011).
In 2012, Imperial Metals Corp. conducted underground diamond drilling on the Boundary zone. Drillhole NDU12-196 was the highlight of this successful program, returning 12.8 metres (estimated true width of eight metres) grading 4.73 per cent copper, 2.61 grams per tonne gold and 30.05 grams per tonne silver (Press Release, Imperial Metals Corp., January 7, 2013).
