Black Lake Project - Maps and Figures
The Company has planned a radon and helium survey at Black Lake while snow cover remains and the low-lying swamps in the northern part of the Project are still frozen. C.O. Geosciences Inc. of St-Lazare, Quebec has developed for ALX a new technique of augering into frozen swamps to collect sediment samples for analysis.
Approximately 160 radon and helium sample sites are planned on a grid established in the northernmost area of the Project located above the main conductive system. Historical drilling bracketing the survey area has intersected faulted and fractured rocks, which are more likely to allow the escape of radon, helium, and other gases known to be emitted by uranium mineralization. Anomalous uranium mineralization was intersected in Eldorado Nuclear Ltd. 1980 drill hole RL-4B and in two drill holes completed by ALX in 2017 (BL-155 and BL-156) at the edges of the 2019 survey area, which has received sparse drill testing in relatively shallow sandstone cover (225 to 250 metres to basement).
