Purepoint Uranium Group (TSXV:PTU) has expanded its recently announced discovery of high-grade mineralization at its Hook Lake joint venture with a 40 meter stepout. Furthermore, the final drill hole of the program intersected 8.6 metres of uranium mineralization that includes a 20 cm interval of semi-massive pitchblende.
Purepoint Uranium Group (TSXV:PTU) has expanded its recently announced discovery of high-grade mineralization at its Hook Lake joint venture with a 40 meter stepout. Furthermore, the final drill hole of the program intersected 8.6 metres of uranium mineralization that includes a 20 cm interval of semi-massive pitchblende.
As quoted in the press release:
Drill hole HK15-33 intersected mineralization 40 metres up-dip of drill hole HK15-27 that returned 12.90% U3O8 over 0.4 Metres within 2.23% U3O8 over 2.8 metres. The step-out hole averaged 8,900 counts per second (cps) over 8.6 metres from the downhole gamma probe and returned a peak reading of 32,600 cps from an interval of semi-massive pitchblende. The uranium mineralization of HK15-33 again coincides with the upper contact of a strongly sheared Graphitic-pyritic Pelitic Gneiss unit. Assay results will be provided as soon as they become available.
Drill hole HK15-31 tested the structure intersected by HK15-27 that returned 2.23% U3O8 over 2.8 metres at depth by backing the drill up 35 metres and drilling with a dip of -70 degrees. The unconformity was reached at a depth of 158 metres then Quartz-rich Pelitic Gneiss displaying hematite, clay and chlorite alteration was encountered to 409 metres. Two zones of anomalous radioactivity, 3.4 and 4.1 metres in thickness, were encountered with grades slightly lower than 0.05% eU3O8 between 387 and 396 metres. A brecciated and re-silicified quartz vein, a product of hydrothermal fluids, was intersected at the projected depth of the high-grade mineralization. Graphitic-pyritic Pelitic Gneiss was encountered between 409 and 432 metres, Pelitic Gneiss was then drilled to 499 metres and the hole was completed within Granitic Gneiss at 549 metres.
Drill hole HK15-33 was collared 35 metres west of the HK15-27 drill hole and was drilled with a dip of -70 degrees. Quartz-rich Pelitic Gneiss with hematite, clay and chlorite alteration was encountered to a depth of 362 metres and a 4.4-metre wide clay-altered fault zone, which returned an average of 1,500 cps from the downhole probe, was intersected between 304.4 and 308.8 metres. Strongly sheared Graphitic-pyritic Pelitic Gneiss was encountered to 392 metres with the targeted mineralized zone being intersected over 8.6 metres immediately above the graphitic unit between 344.0 and 352.6 metres. The mineralized zone included a 20-cm interval of semi-massive pitchblende. Moderately clay altered Quartz-rich Pelitic Gneiss was then drilled to 445 metres followed by unaltered Granitic Gneiss to the completion depth of 542 metres.
