Patterson Lake South Project

PLS Title Map

Client: Fission Uranium

Year: 2013 – 2014

In early 2013 RadonEx, in collaboration with the JV clients, designed a completely unique radon-in-water survey. Execution of the resultant EIC radon-in-water program from the ice of Patterson Lake by RadonEx Vice-president Joshua Owen, led directly to the drilling discovery of the Patterson Lake South (PLS) uranium deposit – the biggest mineral discovery of 2013 in the world. The survey outlined a number of radon-in-water anomalies and drill testing of the largest anomaly led to the discovery of the R390E Zone.  After the discovery of R390E Zone, drilling at PLS has been focused on radon anomalies with coincident geophysical conductors.  During 2013 six (6) radon-in-water anomalies were tested and 6 areas of new mineralization were discovered (including 5 new mineralized zones), a perfect anomaly-to-discovery ratio.

In the summer of 2013 RadonEx crews returned to PLS to conduct a RFM radon in soil survey directly west of the R00E Discovery Zone.  The survey was successful in locating a number of radon targets for follow-up drill testing.  Drill rigs at PLS have now moved from the lake and are focused on the area west of the R00E Zone. So far one anomaly has been drill tested and another new zone (R600W) was discovered, continuing the PERFECT anomaly-to-discovery ratio at PLS!

This brief selection of news releases refers to RadonEx’s role in the PLS discovery:

From Fission Energy release of February 19, 2013, commenting on the 390 Zone discovery drill hole, Ross McElroy, President, COO, and Chief Geologist for Fission stated “Hole PLS13-038, based on anomalous results of a recently completed radon in water and sediment survey, clearly builds on the strong start we’ve had to the winter program at PLS….Further drilling will be focused in the area around this new exciting drill result” This release went on stating, “The drill hole location was based on anomalous results of a recently completed radon in water survey…. RadonEx Exploration Management of Montreal were contracted to conduct a 191 station Lake Water and Sediment Radon survey over Patterson Lake, on strike to the east of the mineralization encountered in drilling last November 2012”.

On August 12th 2013, in a news release entitled, “Fission Hits 13.41m Total Composite “Off-Scale” Radioactivity in 48.5m of Mineralization at R780E Zone”, Fission go on to state that, “The R780E zone discovery was the result of follow-up by drilling of a radon in water anomaly identified during the January – February 2013 survey conducted by RadonEx Exploration Management.”

Alpha Minerals stated on September 23rd 2013, “This first hole on line 585E, PLS13-098, intersected 76.0m total composite mineralization within 107.5m section (62.5m – 170.0m), including 7.62m total composite off-scale radioactivity. [….] This is the fourth successful test of Radon targets from the survey carried out by RadonEx earlier in 2013 for the Joint Venture.”

On the discovery of the R945E Zone, Alpha Minerals on October 9, 2013 stated: “The R945E zone discovery was the result of follow-up by drilling of a radon in water anomaly identified during the Phase 2 EIC radon in water and sediment survey completed during April 2013 by RadonEx.  The radon anomaly is the strongest radon in water anomaly to date.”

On the discovery of the R600W Zone, Alpha Mineral on November 12, 2013: “The R600W zone discovery was the result of follow-up by drilling of a radon in soil gas anomaly identified during the summer program by RadonEx of Montreal”.
