Blue Sky Uranium Corp. (TSXV: BSK) (OTC: BKUCF) is resuming its 4,500 m exploration drilling programme with new holes planned at the Ivana Central target.
The drilling is located 10 km north of the company’s Ivana Deposit at its wholly-owned Amarillo Grande Uranium-Vanadium Project in Rio Negro Province, Argentina (AGP).
Six holes totalling 286 m were drilled at Ivana Central in 2020 before the programme was paused, leaving approximately 1,200 m to be completed at this target.
Two of the first six holes at Ivana Central intersected anomalous uranium, including 120 ppm U3O8 over 1.0 metre in hole AGIC-01 and all holes returned anomalous vanadium and pathfinder elements similar to those associated with uranium mineralisation at the Ivana deposit. The new drilling will test the continuity of the prospective horizons intersected in the initial holes.
“Ivana Central is the next area we are evaluating in our continued push to identify and delineate new mineralization and deposits at the district-scale Amarillo Grande project. We look forward to completing this tranche of drilling so that we can plan detailed follow up and advance to testing other targets in the Ivana area,” President and CEO. Nikolaos Cacos, said.
A total of 1,584 metres have also been completed at the Ivana North target (see October 21, 2021 News Release.) Following completion of the current tranche of drilling at Ivana Central, approximately 1,500 metres of drilling will be deployed in refining delineation of areas with the best results from both targets.
Ivana Central Target Details
Ivana Central is a blind exploration target consisting of a mainly soil-covered depression covering an area of five by nine km. This target zone was initially identified by Blue Sky’s previous joint venture partner Areva in 2013 via a drilling programme of 11 core holes totaling 2023.5 metres, with depths ranging from 110 to 280 m, in the southern sector of the Amarillo Grande project.
In 2018 Blue Sky’s exploration team relogged, sampled and re-interpreted those holes and applied the in-house geological and exploration models and experience that have been developed and refined as the Ivana deposit has been discovered and advanced.
This work identified a suite of pathfinder element anomalies, including molybdenum, selenium, cobalt, lanthanum, rhenium, yttrium, lead, and zinc, that the company employs as geochemical indicators to vector towards blind uranium deposits.
The exploration work at Ivana Central continued with auger-holes, radiometric surveys and pit-sampling, followed by induced polarisation (IP) Pole-Dipole tomography. From the auger-holes surveyed, radiometric anomalies were detected in some holes and at several different depths; some are open to depth.
The sampling programme encountered reduced carbonaceous alteration and carnotite mineralisation. The IP survey detected areas with high chargeability anomalies interpreted to represent moderate to low levels of disseminated pyrite, suggesting proximity to an oxidation-reduction (REDOX) zone as potential “trap” for uranium mineralisation.
This information was used to plan the initial reverse circulation (RC) drilling programme originally launched in 2020, as reported on March 2, 2020. Two holes successfully intercepted uranium-vanadium anomalies at the expected depths, with a third showing weak uranium values. Those intercepts suggest that the mineralisation potentially continues to the west, onto a mineral tenure for which permits were pending at that time but which have now been secured. The new programme is designed primarily to test that potential westward continuity of the mineralisation as well as to test some undrilled areas to the east showing IP chargeability anomalies.
The drilling programme will employ a multipurpose direct circulation hydraulic drilling rig on tracks. This drill produces wet chip samples which are collected from sampling buckets every metre; the drill rig also has the ability to recover drill core.
Every hole will be surveyed with a calibrated radiometric Mount Soprys probe. An additional geoelectrical SP-SPR survey will be completed on holes in order to approximate the location of geological contacts between sedimentary units.
