Located 14 kilometres east from the Sand Lake uranium deposit (1.3 metres @ 22% U3O8) and only 6.5 kilometres west of highway 905, the Madison property has seen 11 historic drill holes by Eldorado, Denison, and Cameco, with only one occurring after 1989. Sandstone cover is very thin at Madison at only 60 metres. Historic drilling has returned intersections of up to 217 ppm U3O8.
IsoEnergy recently completed a 20 line-kilometre DC-Resistivity survey at Madison. Results have been compiled with an airborne electromagnetic (VTEM) survey flown by NexGen in 2014. Interpretation of the combined datasets has resulted in several drill targets, many of which are discrete VTEM anomalies coincident with DC-Resistivity lows and/or magnetic lineaments.
