Purepoint Unveils Results of the Red Willow North EM Survey

Purepoint Uranium Group has announced the completion of an airborne electromagnetic (EM) survey at its Red Willow North property.

The Red Willow North project, located on the northeastern edge of Saskatchewan's Athabasca Basin, is also adjacent to Rio Tinto's Hatchet Lake Project. Purepoint has signed an earn in agreement with Rio Tinto for the advancement of the project.

The survey was a helicopter-based VTEM plus Time Domain EM survey conducted by Geotech. The helicopter was flown in two diverse directions over the Topping Island conductor to collect magnetic and EM data over 255 line kilometres of VTEM at a line spacing of 125 m.

Following are the highlights of the survey:

  • The EM conductor is more than 6 km in length and arcuate in shape.
  • The Topping Island conductor’s location seems to be the eastern side of the conductive trend of the Richardson-Crooked Lake. Over 0.8 m along the lake, Denison Mines/Virginia Energy have encountered basement mineralization of up to 0.15% eU3O8.
  • There are several lateral displacements in the conductor. These could be interpreted as faults that could represent high priority drill targets.
  • In the 1970s, there was a pitchstone cobble discovered on Topping Island. The cobble had off-scale radioactivity (>99,999 cpm) and was situated glacially down-ice of the conductor.

A recent VTEM survey stated that there is an inward dip in the eastern portion of the arcuate conductor that suggests a basin structure. On the other hand, the conductor’s northern arm shows a sudden change when it trends towards the west, showing an outward dip. These results reveal the presence of a synform that plunges to the west and another movement on the north flank.
