The angled hole, which is located 555m west of the Triple R deposit, yielded high-grade, shallow depth mineralization, including 14.74% U3O8 over 9m within a larger interval of 3.36% U3O8 over 44m.

Said to be the first hole at the land-based R600W zone, the PLS15-343 encountered large amounts of strong anomalous radioactivity, while follow-up including PLS15-352 and PLS15-360 also showed wide intercepts of radioactivity.

Fission president, COO, and chief geologist Ross McElroy said: "The R600W zone is emerging as an impressive high-grade zone and importantly, it is open in all directions.

"Encountering this grade and width 555m from the Triple R deposit is tremendously exciting and we are looking forward to receiving the assays from our follow up holes at the zone.

‘Just as importantly, this hole has very similar geology to the Triple R deposit and our recently announced winter program expansion will focus on the R600W."

During the summer 2013 program, the follow-up by drilling of a radon in sediment anomaly identified R600W zone.

The radon anomaly is located along an ENE trend, parallel and just north of the PL-3B EM conductor, between 540W and 630W and could host inferred north-south cross cutting structures, the company said.

In 2015, five additional holes intersected mineralization at the R600W with significant widths of high-grade radioactivity, compared to five holes identified with low grade mineralization in 2013.
