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 $500,00.
There is evidence of a significant mineralized alteration system within the property where float samples grading 119 g/t Au (Gold) and 273 g/t Ag (Silver), veins exposed by trenching grading 66 g/t Au, and wide low-grade alteration zones typical of epithermal gold deposits. Recent drilling intersected 17.7 metres (m) of 24.5 g/t Au, including 6.78m of 50.76 g/t Au and, in a separate hole, 1.65m of 175 g/t Au and 249 g/t Ag, including 0.65m of 285 g/t Au and 255 g/t Ag.
In late 2017, Westhaven discovered a significant gold-bearing vein system, the South Zone.
In 2018 thus far we’ve completed 17 diamond drill holes (DDH) totaling 6,360 metres.
As of October 17, 2018 assays are pending for DDH’s SN18-15 through SN18-17 from the recently completed 10 hole 3,721 metre program.

Westhaven is planning to initiate a fully financed, follow-up drill program in November 2018. The property borders the Coquihalla Highway and is only 35 kilometres from the city of the Merritt, allowing for low cost, year-round exploration.
Gareth Thomas, President & CEO of Westhaven stated, “We are excited to report the widest high-grade drill intercept to date at Shovelnose of 17.70m of 24.50 g/t Au and 107.92 g/t Ag, including 6.78m of 50.76 g/t Au and 203.54 g/t Ag (hole SN18-14). It is important to highlight that hole SN18-14 is 300 metres to the southeast of hole SN18-12, (previously announced October 2, 2018) which contains the highest-grade gold assays to date including 1.65m of 175 g/t Au and 249 g/t Ag, including 0.65m of 285 g/t Au and 255 g/t Ag. These results further validate management's belief that this property has the potential to host multiple economic gold deposits. Assays pending include hole SN18-15 which is 100 metres to the southeast from hole SN18-14 and contains visible gold. We are initiating a fully financed, follow-up drill campaign to begin in early November as we look to advance this important new discovery."

To date at the Shovelnose gold project there's been 64 drill holes completed (2 were abandoned in overburden) for a cumulative total of 16,000 metres, in five separate target areas; the Line 6 Zone, Mik Zone, Tower Zone, Alpine Zone and the recently discovered South Zone.
In January 2018, the Company announced the results of a recently completed drill program that consisted of 7 holes totaling 3,269 metres of diamond drilling. This drill program was successful in discovering a new quartz vein system, the South Zone. This target was first outlined by ground magnetics as a northeast trending mag low anomaly, and then confirmed with 2 drill holes SN17-06 and 07. Drilling intersected a 370 metre long zone of quartz veining in SN17-06 and a 316 metre long zone of quartz veining in SN17-07.
It is management’s belief that these newly identified gold mineralized structures in the South Zone are likely the feeder zones responsible for the gold mineralization found near surface in the Alpine Zone. This quartz vein system remains open along strike to the northeast and southwest. The broader zone of gold mineralization and associated metre-scale quartz veins (to 4.3m width) remains open to the southwest. This target is just the southernmost extent of drill testing along the 1,000 metre long north-south trending Alpine Zone, which has had only limited shallow drilling to date.
The Alpine zone, located approximately 350 metres east of the Tower zone, is defined by a 1 kilometre long chargeability anomaly trending to the northwest. In the northern portion of the anomaly, drilling intersected ginguro quartz veins in rhyolites. In the southern portion of the anomaly, the chargeability delineated a thick (to 150m thick) interval of siliceous crystal lithic tuff similar to the upper silicified tuffs intersected in the Tower zone that is striking northwest (parallel to the Tower zone) and dipping approximately 35° to the southeast.
Quartz occurs primarily as flood zones and ginguro veins and stockworks. Gold mineralization occurs over large intervals within the upper rhyolite tuffs averaging approximately 0.23 g/t Au and 1.4 g/t Ag over 161.1 metres (SN16-07) and containing smaller intervals of up to 16.7 g/t Au over 0.5 metres (SN16-02), 8.3 g/t Au and 77 g/t Au over 0.2 metres (SN16-06), 3.6 g/t Au and 24 g/t Ag over 2.0 metres (SN16-07), and 3.3 g/t Au and 8 g/t Ag over 1 metre (SN16-08).
Quartz veins within the upper crystal lithic tuffs dip predominately 40° westward. Chargeability inversions delineated a moderately high coincident chargeability and resistivity anomaly dipping 40° westward, suggesting a possible feeder zone to the upper mineralized zone that has yet to be tested by drilling.
The Tower zone, located approximately 1,200 metres south of the cell/radio tower on the summit of Shovelnose Mt, is underlain by the Pimainus Formation of the Spence's Group, consisting of flat lying limonite-stained felsic crystal lithic tuffs that have been intensely silicified from surface to a depth of approximately 60 metres. These tuffs are underlain by nonmineralized heterolithic tuffs and rhyolite flows. Silicification is pervasive and/or localized along fractures and vuggy/drusy cavity fillings to the west and occurs within stockwork and veins to the east.
Quartz veining within the upper crystal lithic tuffs occurs as; 1) light grey to white chalcedonic veins occurring as narrow veins to stockworks, 2) dark pyrite-rich quartz (“ginguro”) veins, 3) silica flooding zones, and 4) quartz breccia infilled with strongly deformed dark pyritic quartz exhibiting foliation, layering, ribbon, tension gashes, etc developed near the Tower Creek fault zone. Grey quartz gets its colour from up to 10% fine pin-prick size pyrite disseminated inside veining. Pyritic quartz veins, occurring in the southern portion of the Tower zone, have returned assays grading up to 1.7 g/t Au. Recent drilling intersected a feeder zone to the upper zone mineralization to a depth of 250 metres striking northwest and dipping approximately 70° westward, paralleling the Tower Creek fault. At depth, this feeder zone occurs as white quartz stockwork containing high levels of silver and low levels of gold mineralization.
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.
