The Lardeau property comprises three claims totaling 5386.5 Ha along the west side of the Lardeau River, covering prospective Index and Jowett Formation rocks. The heavily vegetated area contains three B.C. RGS Ni-Co anomalies (95th percentile) and two lesser anomalies. Limited reconnaissance work along the access roads at Lardeau has identified listwanite float in the creeks with anomalous nickel silt samples. Listwanite is an alteration product of nickel-bearing ultramafic rocks, similar to the talc and actinolite schists found at Ledgend. Ultramafic rocks are also associated with the massive sulphides at the Standard showing. Most of the creeks are perpendicular to the dominant northwest trend of the geology and are ideal for detailed (200m spaced) silt sampling.
Cardero collected 126 silt samples at approximately 200-metre spacing from the numerous small creeks which cut across the regional geological trend in the fall of 2017. Three drainages returned highly anomalous Ni (>100 ppm), Co (>30 ppm) and Cu (>50 ppm) values, over up to three kilometres of their length.
Cardero intends to fly helicopter-borne aeromagnetic survey over the north block of the Lardeau claims. Base metal mineralization at Lardeau is expected to be associated with pyrrhotite, which has a strong magnetic signature. New logging roads are also planned for this area and will aid in access for prospecting and geochemical sampling.
