50 Mineral Exploration | amebc.ca Itochu Corporation (20 per cent), and Japan Oil, Gas and Metals National Corporation (2 per cent). In 2019, Nicola Mining Inc. drilled at the New Craigmont Cu skarn project. Among results from the first three holes were 44 m of 0.56 per cent Cu in orebody 3, and 84 m of 0.34 per cent Cu in a 50 m westward step out. The British Columbia Environmental Assessment Office terminated Yellowhead Mining Inc.'s Harper Creek copper project assessment in 2018. However in early 2019, Taseko Mines Limited acquired Yellowhead, renamed the project Yellowhead and is evaluating advancing it. Surge Exploration Inc. trenched at its Hedge Hog project, following up in-soil geochemistry anomalies from a 2018 survey. The primary target is VMS mineralization as suggested by sulphide boulders discovered in the 1990s. Of 29 excavations, 25 reached bedrock. Ni-Cu-Co-precious metal projects The Iron Lake project is a Cu-Au-Pt- Pd-Co-Ni target in mafic and ultramafic intrusive rocks. Eastfield Resources Ltd. reported carrying out an IP survey. The property is subject to an option agreement with GK Resources Ltd. Tungsten projects Happy Creek Minerals Ltd. drilled 372.5 m in two holes near the Nightcrawler zone at its Fox Tungsten project. Results include 6.3 m 0.43 per cent WO 3 and 4 m of 0.29 per cent WO 3 at the Nightcrawler zone. Fox is a skarn prospect with 582,400 t of 0.826 per cent WO 3 (Indicated) and 565,400 t of 1.231 per cent WO 3 (Inferred) in three zones. Cobalt, base and precious metal projects Blackstone Minerals Ltd.'s work at the BC Cobalt project included soil and stream- sediment geochemistry and mapping. Specialty metal projects Delrey Metals Corp. flew an airborne survey and identified a large magnetic anomaly at its Peneece Fe-Ti-V project. Delrey increased the size of the property to cover the anomaly. Previously called Wigwam Magnetite, this prospect comprises a large, low grade (5 to 10 per cent) titaniferous magnetite deposit. SOUTH CENTRAL AND SOUTHWEST REGIONS PUBLIC GEOSCIENCE 2018-2019 Celebrating its 125th anniversary in 2020, the British Columbia Geological Survey (BCGS) is the oldest scientific organization in the province. The Survey conducts research to establish the geological evolution and mineral resources of the province. It partners with federal, provincial and territorial geoscience agencies and other national and international organizations. Drawing on continuously advancing concepts and technologies, the Survey creates knowledge to guide societal decisions centred on the Earth sciences, connecting government, the minerals industry and communities to the province's geology and mineral resources. The information provided by the Survey is used for effective mineral exploration, sound land use management and responsible governance, benefitting decisions that balance the economy, the environment and community interests. It delivers reports, maps and databases, which can be freely accessed through MapPlace 2, the BCGS geospatial web service. The largest field project in 2019 was centred on the northern Hogem Batholith and adjacent rocks of the Takla and Cache Creek groups. In its second year, the project will provide a modern understanding on the controls of diverse mineralization types in the region, and includes both bedrock and surficial mapping. An ancillary project evaluated the production of digital elevation models from drone-mounted optical systems, and how these models can be used to support field mapping and exploration. North of the Hogem Batholith, the second year of a TGI-5 partnership with the Geological Survey of Canada was completed. This study, designed to establish the geological framework and geochronology of the Polaris ultramafic intrusion, will be integrated with work on the Tulameen ultramafic body to create a new model for Ni-Cu-PGE ore-forming processes in these Alaskan-type intrusions. The BCGS also partnered with the Bradshaw Research Initiative for Minerals and Mining at the University of British Columbia on a project that examines the feasibility of sequestering carbon dioxide through reactions with alteration minerals in serpentinized ultramafic rocks. Field activities centered on the Trembleur ultramafic unit in the Cache Creek terrane and will be followed by province-wide delineation of serpentinized ultramafic bodies that could potentially sequester carbon dioxide. In the Golden Triangle of northwestern British Columbia, a new multi-year mapping project was started to further refine the stratigraphy of the Hazelton Group and associated mineralization near Kitsault. Also in the northwest, field work in the Dease Lake area examined critical sections to support a report summarizing three years of mapping in an area rich in mineral potential. A pilot project was undertaken in northern Vancouver Island to test panned stream-sediment and water geochemistry combined with Pb isotopic compositions to explore for metallic deposits in glaciated terranes. A depth-to-bedrock study was started along the Quesnel arc in the largely till-covered area between the Mount Milligan and Mount Polley porphyry Cu deposits, using surface and subsurface data from assessment reports, water wells, and bedrock and surficial maps. The BCGS houses, maintains, and regularly updates numerous databases,
