The survey extension, which was completed April 21, 2013, covered 220 stations on a grid with sample spacing 25 metres north-south by 50 metres east-west. Highlights include:
- Strongest radon-in-water anomaly to date (13.3 picocuries per litre) -- located approximately 170 metres northeast and along strike of the R780E radon anomaly;
- Six new radon anomalies, in addition to the five anomalies identified during the initial survey, all associated with known conductors and offsetting structures;
- The easternmost radon anomaly located some 1,500 metres east-northeast along strike of the R780E zone has been confirmed, refined and extended;
- The radon survey appears to have successfully detected uranium sources at greater than 50 metres depth that justify further drill testing.
Ross McElroy, president, chief operating officer and chief geologist for Fission, commented: "Radon survey results have been used by Fission's technical team to great success at PLS and the technique was instrumental in identifying the first pass holes at two of the three discovery zones. These survey results have delivered new and highly promising targets as we continue to plan for our Summer drill program."
