SASKATCHEWAN – The first two summer holes at the R1515W zone hit high grades and wide mineralization in multiple stacked lenses at the Patterson Lake South project of Fission Uranium from Kelowna, B.C. The zone has been expanded both laterally and down-dip.

The shallow R1515W zone – discovered during winter 2017 drilling – is located on land along the western strike extension of the Patterson Lake Corridor, west of both the Triple R deposit and the R840W zone.

Two holes were of particular interest:

  • Hole PLS17-562 returned 5 metrestotal composite mineralization over a 148.5-metre section (between 104.0 to 252.5 metre), including 3.37 metres  >10,000 cps.
  • Hole PLS17-561 returned 0 metretotal composite mineralization over a 162.5-metre section (between 111.0 to 273.5 metres), including 1.38 metre  >10,000 cps.

Fission reminds readers that uranium mineralization at PLS has been traced by core drilling approximately 3.17 km along an east-west strike length in five separated mineralized zones – R1515W, R840W, R00E, R780E and R1620E. Thus far only the R00E and R780E have been included in the Triple R deposit resource estimate.

The Triple R deposit is estimated to contain indicated resources of 2.3 million tonnes grading 1.58% uranium oxide plus an inferred resource of 901,000 tonnes at 1.30% U3O8.
