CanAlaska Uranium Ltd. reports that plans have been made for drill testing of the northern portion of Grid 5, where Cameco identified multiple intercepts of uranium mineralization in the most recent drill programs. Under the Joint Venture with Cameco, CanAlaska will act as Operator and plans to drill 7,000 metres in 10 drill holes this summer to endeavor to intersect lenses of higher-grade uranium mineralization. West McArthur uranium discovery: In August 2017, Cameco intersected the first high grade uranium mineralized intervals on the northern portion of the five-kilometre long Grid 5 target area at the West McArthur uranium project. The project extends over 36,000 hectares and the eastern boundary is 6 kilometres (4 miles) northwest of Cameco's majority-owned McArthur River uranium mine and associated infrastructure. To date three holes have intersected mineralization, up to a maximum of 1.51% U3O8 over 5.5 metres. The main anomalous zone is situated at a flexure in the three recognizable conductors, (the "C10" graphitic conductor package). Four kilometres to the east, the C10 conductor hosts the Cameco/Orano Fox Lake high grade uranium deposit. Three graphite-bearing rock units ("conductors") define a 6.6 km long conductive trend west from the Fox Lake uranium deposit onto the West McArthur project. The first 1.6 kilometres (one mile) of this trend onto the project hosts a significant flexure, and the conductors rotate to the south. The large ZTEM geophysical anomaly shows that this trend continues for a further five kilometres to the south, and is shown as insert in Figure 1. High grade mineralization was intersected at target B, where the trend bends southward, 1,600 metres west of the property boundary. The eight drill holes carried out by Cameco, under their previous option to earn 30% of the project, intersected a series of geochemical halos around and above uranium mineralization. The halos are very distinctive and characteristic of known uranium deposits. The size of the halos, with boron and uranium values to near surface, and high uranium and base metal values at the unconformity, suggest the possible presence of significant uranium mineralization.
