Fission Regional Exploration Drilling At Saloon East Hits Strongest Radioactivity to Date Outside of the Triple R Deposit
A total of 65.5m of anomalous radioactivity was detected on the downhole gamma probe, with the best intervals occurring between 205.7m to 216.9m, 285.4m to 296.9m and 323.5m to 337.9m with peaks of 4,077.3 cps, 1,916.2 cps and 1,601.9 cps, respectively. PLS24-681 was drilled at the main Saloon target area, testing the strongest radioactivity intersected in PLS24-661 30m along strike to the southwest. Bedrock was intersected at a depth of 114.4m and like other drillholes in the Saloon area, consisted of alternating very strongly silicified, hematite-clay altered, brecciated to mylonitic rocks to the end of the drillhole at 332.0m. Five zones of anomalous radioactivity were intersected, with the best occurring from 296.3m to 302.1m with a peak of 2,830.5 cps. PLS24-680 tested a strong EM conductor along the South Patteson trend. It is interpreted that the top 80m of bedrock in this drillhole, consisting of Cretaceous mudstone and altered bedrock were washed away during drilling, and solid basement was intersected at a depth of 107.3m. Basement units consisted of an upper sequence of variably chlorite-clay altered intermediate orthogneiss and quartz-feldspar-biotite-garnet gneiss with wet-rock style alteration, followed by graphitic cataclasite and an intensely silicified unit. The silicified "hanging wall" was underlain by a clay altered graphitic fault zone and then mafic gneiss, sheared granitoid and quartz-feldspar-biotite-garnet gneiss to the end of the hole at 410.0m. Eight zones of elevated radioactivity totaling 25.9m were intersected between 269.4m and 360.4m. Strong radioactivity was detected from 306.7m to 313.5m hosted in the clay altered graphitic fault zone with a maximum of 10,428.7 cps, and from 325.3m to 326.4m hosted in a hematite-clay altered shear zone with a maximum of 7,833.6 cps. PLS24-682 was drilled to test 25m up-dip of the strong radioactivity intersected in PLS24-680. Bedrock was encountered at 47.0m downhole and consisted of Cretaceous mudstone to 89.0m, followed by a similar hanging wall sequence of chlorite-clay altered intermediate orthogneiss and quartz-feldspar-biotite-garnet gneiss with wet-rock style alteration, graphitic cataclasite and a strongly silicified "hanging-wall". The silicified hanging wall was underlain by a clay altered graphitic fault zone and then sheared granitoid, mafic granofels and quartz-feldspar-biotite-garnet gneiss to the end of the hole at 344.0m. Six zones of anomalous radioactivity were encountered, with the best occurring from 267.7m to 273.3m and 296.1m to 301.2m returning peaks of 1,950.5 cps and 5,841.8 cps, respectively. PLS24-684B was drilled to test 25m down-dip of the strong radioactivity intersected in PLS24-680. Bedrock was encountered at 20.0m downhole and consisted of Cretaceous mudstone to 68.0m, followed by a hanging wall sequence of chlorite-clay altered intermediate orthogneisses and quartz-feldspar-biotite-garnet gneiss with wet-rock style alteration, graphitic cataclasite and a strongly silicified zone. The silicified zone was underlain by a thin clay altered graphitic fault zone and then primarily quartz-feldspar-biotite-garnet gneiss to the end of the hole at 401.0m. Five zones of anomalous radioactivity were encountered, with the best occurring from 278.0m to 289.6m and 315.4m to 319.4m returning peaks of 12,677.6 cps and 6,736.7 cps, respectively. Saloon - General: PLS24-651 was drilled 1 km southwest of the main Saloon target area, testing an airborne EM conductivity high coincident with a magnetic low running along the southern flank of a broad magnetic high. The drillhole intersected bedrock at a depth of 122.5m downhole, consisting of an upper sequence of mafic and quartz-feldspar gneisses to 214.0 m, a variably silicified and graphitic zone to 325.3m and quartz-feldspar gneisses to the end of the hole at 458.0m. Two 0.3m zones of anomalous radioactivity were detected on a 2PGA-1000 gamma probe, with maximums of 591.7 counts per second (cps) and 745.6 cps at 369.1m and 442.0m, respectively. PLS24-667 tested a northeast trending EM conductor located south of the main Saloon target, within a broad magnetic low. Bedrock was intersected at a depth of 130.6m and consisted of an upper package of coarse garnet quartz-feldspar-biotite gneiss and intermediate orthogneiss to 223.2m, followed by variably graphite altered and structurally deformed mafic gneiss, intermediate orthogneiss and mylonite to the end of the hole at 389.0m. No anomalous radioactivity >500 cps was detected on the downhole gamma probe. PLS24-670 tested northeast of the main Saloon target area, along a strong EM conductor coincident with a magnetic low. A 1.4m thick lens of Cretaceous mudstone was intersected at 110.6m downhole and basement units consisted primarily of intermediate orthogneiss and mafic gneiss to the final depth at 364.0m. Two broad fault zones with moderate to strong clay and graphite alteration were intersected between 194.1m to 223.4m and 251.4m to 275.0m. Four thin zones of anomalous radioactivity were detected on the downhole gamma probe associated with the graphitic damage zones, with a peak of up to 2,668 cps between 245.8m and 246.4 m. PLS24-672 tested the clay altered, graphitic fault zones intersected in PLS24-670 up-dip near the top of bedrock. Bedrock was intersected at a depth of 115.3 m downhole and consisted primarily of variably altered intermediate orthogneiss and mafic gneiss to the final depth at 252.7 m. Strong graphite-clay alteration was intersected in a fault zone between 191.0 and 227.8 m. Three zones of anomalous radioactivity were detected on the gamma probe, including a continuous 4.7 m thick interval between 185.1 and 189.8 m with a peak of 2,860.9 cps. PLS24-674 was drilled 290m north of PLS24-670 and 672 testing a parallel northeast trending EM conductor system, termed the South Patterson trend. A 15.2m thick lens of Cretaceous mudstone was intersected starting at 97.8m, followed by a complex, interfingered sequence of variably chloritic, silicified quartz-feldspar-biotite-garnet gneiss, intermediate orthogneiss and mafic gneiss cut by numerous strongly graphitic shear zones to a final depth of 486.6m. Interpreted dravite breccia, occurring as cm veins to 10's of cm thick breccia was intersected throughout the drillhole.
