The property is centered at 52°55’32.3” N and 123°44’10.8” W (NAD83), between Fishpot Lake to the west and Marmot Lake to the east. The Nazko property covers parts of BCGS maps 093B.082 and 093B.092. The Nazko property consists of two contiguous mineral leases that cover 400.00 hectares (ha) of land that are encompassed by seven mineral claims that cover 2261.20 ha. The leases and claims that comprise the Nazko property are 100% owned by CANLAVA Mining Corp. (CANLAVA). Access to the property is west from Quesnel via the paved Nazko Road to the village of Nazko, then west along the well-travelled gravel 4000 Road to the Nazko cone and approximate centre of the property. The Nazko property covers the Recent Nazko cinder cone where scoria and tephra is currently being mined and processed on mining leases into finished product by owner- operator CANLAVA. Underling rocks include prospective Eocence Ootsa Lake Group rhyolitic volcanic rocks and Cretaceous Skeena Group fine to coarse-grained siliciclastics. The Nazko property has only recently been the subject of exploration for precious metals. Geochemical surveys have outlined several anomalies that warranted follow-up work. In 2016, bedrock mapping, prospecting and sampling conducted over the southern half of the property identified a previously unrecognized window through the young volcanic cover. The older rocks are locally Fe and Mn-altered chert pebble conglomerate and coarse-grained sandstone of the Skeena Group; they are overlain to the west by weakly altered rhyolitic volcanics of the Ootasa Lake Group. In 2017, additional bedrock mapping, prospecting and sampling examined the southerly projection of the Skeena Group – Ootsa Lake Group contact in an effort to identify gold mineralization that is suggested by elevated concentrations of pathfinder elements. The work identified altered Skeena sediments and Ootsa Lake Group volcanics, but sampling returned only background levels of gold and silver. It is recommended that CANLAVA conduct a VLF-EM survey across the Skeena Group-Oosta Lake Group contact in an effort to identify anomalies that may be indicative of buried sulphide- rich zones and/or geological structures that may control as-yet undiscovered mineralization. A suggested budget for a 1-week follow-up program of VLF-EM surveying is an estimated $12,000.00. CANLAVA MINING CORP.

Introduction The Interior Plateau region of British Columbia is con- sidered to have high exploration potential as it hosts a variety of deposit types including Late Cretaceous and Eocene epithermal Au and Ag deposits (e.g., Blackwa- ter, Capoose and Wolf) and porphyry Cu and Mo depos- its (e.g., Endako and Chu) ranging in age from Late Ju- rassic to Eocene. Exploration activity has historically been hindered by a limited understanding of the charac- ter and distribution of prospective units owing to the masking effects of overlying Eocene and Neogene ba- salt flows and extensive glacial till cover. The Targeting Resources through Exploration and Knowledge (TREK) project is a Geoscience BC initiative to inte- grate geophysical, geological and geochemical data in order to improve our geological understanding and, ul- timately, reduce the risk associated with exploration in such a poorly understood region (Clifford and Hart, 2014).
