The Line 6 showing is located on Shovelnose Mountain, approximately 5 kilometres north of the community of Brookmere.
The area is underlain by Nicola Group intermediate volcanics and minor intrusives, Spences Bridge Group andesite flows, volcaniclastics, crystal lithic tuffs and rhyolite flows, and Princeton Group basalt flows. Cretaceous rhyolite flows form a cover sequence. Normal faulting along north to northeast- and northwest-trending structures offset the Nicola and Spences Bridge Group rocks.
Locally, gold mineralization is spatially associated with north-northeast– and northwest–trending normal faults and hosted by south-southwest–trending, shallowly west-dipping quartz veins. Gold- bearing veins are preferentially hosted within Cretaceous felsic heterolithic crystal lithic tuffs.
The Line 6 showing comprises a 600 by 400 metre area of south-southwest–trending massive and crustiform quartz veins and local vein breccia zones hosted within sericite argillite-limonite-altered felsic crystal siliceous lithic tuff.
In 2006, a sample (K-R65) of rhyolitic volcanic(?) with quartz veinlets, taken southeast of the occurrence, yielded 0.09 gram per tonne gold and 19.8 grams per tonne silver (Assessment Report 28926).
In 2009, trenching of the showing returned 0.8 gram per tonne gold over 21 metres, including 4.86 grams per tonne gold over 2 metres (Assessment Report 32109).
The Brookmere zone, located approximately 800 metres to the southwest of the Line 6 zone, comprises several extensive vein systems that are exposed in proximity and aligned subparallel to syenite dikes. One vein system has been traced for 200 metres north-northwest. Veining consists of coarse, centimetre-scale cockscomb quartz coating open fractures and fault breccia. The veins are generally south-southeast–striking (160 degrees) with moderate to steep southwest dips (50 to 60 degrees), which is different from the predominantly south-southwest–striking veins at the Mik (MINFILE 092HNE309) and Line 6 zones and therefore do not appear to be the southwestern extension of those zones. Some of the veins appear to have the characteristics of epithermal veins and may be associated with extensively developed silica alteration. Assay results from this zone have yet to return significant gold values.
Work History
The showing was staked in 2005 by Strongbow Exploration and exploration was done on a part of the Shovelnose property. Exploration from 2006 to 2009 exposed four zones of gold mineralization on the property: Mik (MINFILE 092HNE309), Line 6, Tower (MINFILE 092HNE309) and Brookmere. In 2010, exploration was focused on expanding the surface extent of the Mik and Line 6 showings through surface and auger soil sampling, prospecting and ground magnetometer surveys.
In 2011, Westhaven Ventures Inc. optioned the property from Strongbow Exploration Inc. and completed a program including soil and rock sampling, mechanical trenching and diamond drilling. Highlights of this drill program included drillhole 11-SH-005, which returned 0.54 metres grading 2.91 grams per tonne gold (Assessment Report 32921).
