The 15,542 ha Shovelnose property is located near the southern end of the Spences Bridge Gold Belt (SBGB), approximately 30 km south of Merritt, British Columbia. The property is accessible by the Coquihalla Highway (BC Provincial Highway #5) at the Coldwater exit, then by a series of logging roads to the northern and southern portions of the property.
The Shovelnose claims cover prospective stratigraphy in the southern SBGB, a 110 km northwest–trending belt of intermediate to felsic volcanic rocks dominated by the Cretaceous Spences Bridge group. These relatively underexplored volcanic rocks are highly prospective for epithermal style gold mineralization. Low-sulphidation epithermal gold quartz veins occur throughout the range of Spences Bridge Group stratigraphy. Westhaven has a 100% interest in this property subject to a 2% NSR. Westhaven has the option to purchase to purchase 1% of the 2%NSR back for $500,000.
As of 2019, we have drilled 69 holes for a grand total of 18,212 metres of diamond drilling across the entire property focused in five separate target areas; the Line 6 Zone, Mik Zone, Tower Zone, Alpine Zone and the recently discovered South Zone.
In late 2017, Westhaven discovered a significant gold-bearing vein system, the South Zone. In 2018, we completed 22 holes for a total 8,543 metres of diamond drilling.

In February of 2019, Westhaven is planning to initiate a fully financed drill program of approximately 7 holes for 2,500m’s of diamond drilling.

Between the 19th and 20th centuries the discovery of placer gold 75 km to the northwest of Shovelnose ignited the Fraser and Thompson Rivers gold rush (Balon, 2005). Placer gold was mined from gravel bars on major tributaries in the Ashcroft-Lytton-Lillooet district. In particular, the Nicoamen River, located 23 km northwest from Shovelnose Mountain, played a role in initiating the gold rush in the Merritt region.
In 2011, Westhaven Ventures Inc. acquired an option on the Shovelnose gold property from Strongbow Exploration Inc. In the same year Westhaven completed a program including soil (972) sampling, stream silt (28) sampling, rock grab (107) and rock chip (91) sampling, mechanical trenching (146.5 m), and diamond drilling 606m in 7 holes). Drilling tested the Mik (3 holes), Line 6 (3 holes) and Tower (1 hole) showings.
In 2012 Westhaven completed 5.8 line-kilometres (3 lines) of reconnaissance-scaled Induced Polarization and ground magnetic geophysical surveys in the vicinity of the Tower, Mik, and Line 6 showings. Follow-up diamond drilling consisted of 5 holes totaling 778.5 metres. The 2012 drill program tested the Tower zone (holes SN-12-02, 03, and 04), intersecting a zone of intensely silicified, limonite stained rhyolite tuff with pyritized grey chalcedonic quartz flooding. Gold mineralization was encountered in all five drill holes, however, the Tower zone appears to host the largest consistent near surface gold mineralization discovered on the Property to date.
Hole SN-12-04 intersected 106.5 m of very highly silicified breccias with original lithologies and textures mostly obliterated due to the intense silica flooding. Within the 106.5 m long zone of silicification a 53.5 m long zone containing dark grey to black pyritiferous breccia matrix accounted for most of the gold mineralization grading 0.51 g/t Au; 4.6 g/t Ag.
In 2013 Westhaven completed programs consisting of prospecting, geophysical Induced Polarization and ground magnetic geophysical surveys (3.75 line-km on 5 lines) and diamond drilling (8 holes totaling 1,043.0 metres) in the Tower zone area. The main focus of the 2013 drill program was to test extensions of mineralization at the Tower zone.
In 2014 Westhaven completed 6 diamond drill holes totaling 662.5 metres. The drill program was designed to test for extensions and the potential for a possible feeder zone bearing higher grading gold mineralization below or along strike to SN-12-04. One hole was drilled in the MIK showing to possibly undercut gold mineralization discovered during the 2011 drill program.
In 2015 Westhaven completed an airborne Light Detection and Ranging Survey (LIDAR) over an area of 19.5 km2, Induced Polarization (12.75 line-kilometres), VLF-EM (54.94 linekilometres),and ground magnetic (23.45 line-kilometres) geophysical surveys. The most significant discovery was the Alpine showing, a northwesterly trending, moderate intensity resistivity anomaly coincident with a moderate intensity chargeability anomaly, located approximately 450 metres east of the Tower zone that has been defined over a strike length of 1 kilometre. Follow-up diamond drilling consisting of 5 holes totaling 1,408 metres drilled in the Line 6 (2 holes), Tower (2 holes), and Alpine (1 hole) zones.
In 2016 Westhaven completed 9 diamond drilling holes totaling 1,902 metres. Three holes were drilled into the Tower zone in an attempt to ascertain the geometry of possible feeder zones to the upper lower-grading gold mineralized tuffs and six holes tested the Alpine Zone IP chargeability anomaly.
In 2017 a ground magnetics survey was completed over the Tower and Alpine Zones. A northeast trending linear magnetic low was noted truncating the southern extent of the chargeability anomaly.
Drillholes 17-06 and 17-07 targeted the linear magnetic anomaly (Figure 6). Drillhole 17-06 (Az 110°, Dip -50°) was collared 210 metres southwest of drillhole SN16-02. Drilling intersected an upper unit of silicified rhyolite tuff to 266 metres depth, underlain by heterolithic, welded, and rhyolite tuffs to 447 metres depth which were underlain by andesites and basalts to 506 metres depth. Although west dipping quartz veining was noted from bedrock surface to 477 metres depth, gold mineralization was most prominent within the upper rhyolite tuffs averaging 0.52 g/t Au and 1.4 g/t Ag over 85.0 metres (Figure 11). Within this zone higher grading intervals include 1.02 g/t Au and 2.5 g/t Ag over 17.0 metres.
Drillhole 17-07 (Az 110°, Dip -50°) was collared 120 metres northeast of 17-06. Drilling intersected silicified rhyolite tuffs from bedrock surface to 293 metres depth, underlain by heterolithic tuffs to the end of the hole at 431 metres depth (Figure 12). Numerous steeply dipping basalt dykes were intersected near the bottoms of both 17-06 and 17-07. Similar to 17-06, west dipping quartz veining was noted throughout the hole and gold mineralization was most prominent within the near surface silicified rhyolite tuffs averaging 0.29 g/t Au and 1.1 g/t Ag over 101.0 metres. Within this area higher grading zones include 2.48 g/t Au and 5.4 g/t Ag over 5.7 metres.
