Cardero Resource Corp. announced that continuing surface trenching, sampling and mapping at the Ledgend nickel-cobalt property in south eastern British Columbia is well underway. In addition, approximately 90 line kilometres, or 375 hectares, of drone airborne magnetometer geophysics has been flown. Ledgend is one of five properties in the Kootenay project that together total approximately 8,000 hectares. The property owners and Cardero completed soil, silt and rock sampling on Ledgend in 2016 and 2017, collecting over 1,300 samples that produced significant anomalies for this follow-up work. The properties are located within prospective Lardeau Group metamorphic rocks, the host of several volcanogenic massive sulphide deposits, including the past-producing Goldstream mine located north of Revelstoke. The Ledgend property has exposures of massive and semi-massive sulphides and significant Ni - Co ± Cu ± Zn soil anomalies. Trenches completed to date have exposed mineralized bedrock beneath the soil anomalies, and the magnetometer survey results support interpretations of the possible extents of subsurface sulphides. Current work is focused on soil anomalies within the North Grid, which covers an area measuring 1,100 by 2,000 metres. The central nickel-cobalt soil anomaly is 800 metres in length, with the peak of the anomaly (values up to 0.84% Ni, 0.025% Co) located about 200 metres southeast of the massive sulphides boulders of the discovery showing. Three hand trenches spaced 100 metres apart have been completed so far on this anomaly and vary from 0.5 to over 3 metres in depth. All trenches uncovered interlayered biotite, actinolite-tremolite, and talc-carbonate schist with disseminated sulphides. The actinolite and talc schists are altered remnants of high Ni-Co ultramafic rocks that intruded calcareous sedimentary rocks, and are interpreted as one probable source of the metals. Outcrop east of the end of the TR1000N comprises highly siliceous schist, with fine disseminated sulphides and common fuchsite (Plate 1). This is a classic exhalative horizon. Identical units were uncovered in trench TR1600N-1425, located about 500 metres to the north of the trench TR1000N area. This indicates that favourable rocks of the Central Zone extend over 600 metres of strike length and confirm the soil sampling results. Northwest trending Cu-Zn-Co-Ni anomalies occur along the western and eastern margins of the soil grid. Four trenches have been completed over the East Zone anomaly, which has the most anomalous copper, cobalt, and nickel outside of the Central Zone. Rock units comprise interlayered actinolite, muscovite-biotite and narrow talc schist, with sparse disseminated sulphides in a narrow unit of highly gossanous, calcareous quartzite. Four trenches are planned along the West Zone, which is a two kilometre long, Cu-Zn ± Co-Ag anomaly along the northwest margin of the soil grid, open to the north and southwest. The pyrrhotite-bearing massive sulphides as exposed at the Discovery Showing were considered to be most easily traced in the subsurface with a magnetometer survey. Pioneer Aerial Surveys Ltd. mobilized to the property in mid-June to fly approximately 90 line kilometres of aeromagnetometry, covering 375 hectares over the North Soil Grid. Pioneer used their UAV-MAGTM system, consisting of a multi-rotor UAV platform, a GEM Systems GSMP-35A potassium vapor magnetometer, and GEM Systems GSM-19 Overhauser base station. The survey flew east-west lines spaced at 50m with 500m perpendicular tie lines. Drone-flown magnetometer surveys have the advantage of low-flight speed, resulting in ultra-high-density resolution with the average station separation around 60cm at 10 m/s. Cardero has received plan maps of total magnetic intensity ("TMI"), analytical signal ("AS"), 1st vertical derivative ("VD"), and horizontal derivative ("HD"), as well as a 3D inversion and elevation sections through the 3D model. The Central Zone magnetic anomaly extends over 500 metres farther south past TR0900N, to the southwest corner of the soil grid, merging with the West Zone soil anomaly. The West Zone also has a coincident magnetic anomaly at the north end, separated from the Central Zone anomaly by a northeast trending fault running along upper Ledgend Creek. Trenching is planned for this area.
