Bulk-tonnage, Porphyry Target with High Grades in Drilling, Trenching, Underground Exploration
First explored in the early 1980s, the Bonaparte Gold Property hosts a series of well-developed shear/fracture zones hosting near-surface quartz veins
. The veins have produced high-grade intersections for gold in drilling, trenching and underground sampling. The zones average two-to-three meters in thickness and appear to be located 12 to 15 meters apart within a larger regional structure. Exploration to date indicates the zones are open to expansion in all directions, and a much larger target zone, located east of the original Discovery Zone, was identified in the 2015 drill program.
Bulk Sample Program
In April 2016, WestKam received an underground Bulk Sample Permit from the BC Ministry of Energy and Mines, allowing for the extraction of 10,000 tonnes of ore from the Bonaparte Project. The permitted design of the bulk sample program includes extension of the existing decline approximately 200 meters through to the Grey Jay/Crow vein systems. The program began in early July 2016 and was suspended in late 2016. Subject to financing and other considerations, the program is expected to resume in 2017.
Exploration in 2015: Cooler Creek Zone
A seven-hole, 583.22 metre drill program was carried out in the fall of 2015. Highlights included discovery of a new vein, 450 metres east of the Crow/Grey Jay/Owl veins of the Discovery Zone. This new vein discovery from DDH-15-05 (see November 16 News Release) lies within an anomalous IP resistivity, chargeability and Au/Cu geochemical trend which extends 1.2 kms to the south-southeast and is open both northward and southward. The new zone, called the Cooler Creek Zone, will be the target of drilling planned for 2016.
Exploration in 2014: Discovery Zone Extended
The 2014 program further advanced and tested both the Discovery Zone and porphyry potential. The field program included mapping and prospecting, 3D IP and magnetic geophysical surveys and soil geochemistry.
The Volterra 3D IP and ground magnetic surveys substantially extended the strike length of the high-grade Discovery gold zone trend. The extent of the zone's chargeability and resistivity anomalies has now been traced 1.2 kms from the Discovery Zone to the south-southeast, and the zone remains open. Several parallel features of similar chargeability and resistivity signatures have also been identified. These discoveries provide a number of attractive drill targets for the next phase of exploration.
Southwest of the Discovery Zone, the 2013 surveys discovered a large magnetic anomaly comprised of extreme highs and lows with coincident IP chargeability responses under a younger basalt cap. These results suggested potential for a multi-phase intrusive. Additional Volterra 3D IP and magnetic surveys conducted in 2014 expanded this target zone a further 800 meters to the south. Several chargeability anomalies within this zone present drill targets for the 2015 exploration program.
Copper-Gold Porphyry Potential
Supporting the 2013 exploration IP results are findings published by the British Columbia Geological Survey in Paper 2012-1 entitled "Bonaparte gold: another 195Ma porphyry Au-Cu deposit in Southern British Columbia?" In support of a Cu-Au porphyry target, the Bonaparte Intrusions align with a north-west trending belt of early Jurassic porphyry deposits in the Takomane-Wildhorse Magmatic belt (TWM belt). The metal and alteration assemblages at Bonaparte are shared by porphyry deposits within the TWM belt such as the Brenda Cu-Mo and the Woodjam Au, Cu-Mo porphyry deposits. As well, drilling at Bonaparte in 1986 reported polylithic breccias demonstrating the presence of high-level porphyry processes on the property.
In 1994 a 3,700 metric ton bulk sample of mineralized vein material from surface trenching with an average grade of 26.5 g/t Au produced 3,160 ounces of gold. In 2009 a 3m X 3m decline was collared on the Raven vein and the underground development program was designed to evaluate the vein system at depth. A total of 161m of underground development was completed. An initial underground bulk sample shipment of 364.61 short tons was processed, assaying 0.475 oz/t Au, yielding 161.95 troy ounces of gold.
Diamond drilling beneath the bulk sample pits produced several high-grade intersections including:

for more information and detailed drill results.
One of the key goals of the next exploration program is to establish connectivity between the intersections as part of the property's first NI 43-101 resource calculation.
Second, Smaller Bulk Sample in 2010
In 2010 a small bulk sample from the Crow Vein was shipped to the Kinross Mill in Republic, Washington. The 364-ton sample assayed 0.475 oz Au/ton with the recovered gold sold for $145,783.
