Ivana Process Style Testwork
As an upgrade to the procedure style testwork program for Ivana (see April 6, 2021 Press Release), uranium/vanadium leach tests have actually been finished on the ~ 294 kg averaging 530ppm U 3 O 8 composite bulk sample # 2 prepared from RC chips from the Ivana deposit. The enhanced leach conditions were 60 g/L Na 2 CO 3 and 10 g/L NaHCO 3 , at 95 ° C for 8 hours. For these brand-new tests, uranium healing for the alkaline leach phase was 96%, vanadium healing was 35%.
In December 2018 , Blue Sky finished a very first set of procedure style tests for the Ivana uranium-vanadium mill. Based upon this test work, the total procedure plant healing was 85% for uranium (originated from 89% leach feed preparation healing and 95% subsequent alkaline leach circuit healing); and 53% for vanadium (originated from 89% leach feed preparation healing and 60% subsequent alkaline leach circuit healing) (see February 7, 2019 Press release, submitted on SEDAR).
Preparations are underway for checking the next action in the milling procedure: membrane purification. 4 litres of leach service have actually been gotten ready for the small membrane purification tests, which will recognize the very best nanofiltration and reverse osmosis membranes for the procedure. Seeping of the rest of mineralized sample # 2 is underway to supply feed for the bigger scale membrane purification operation, which will supply options for subsequent solvent extraction tests.
Ivana Resources and Researches
Designing work utilizing external experts has actually been advancing to examine the effect of the extra 3,346 m of drilling in 350 RC drill holes and extra density measurements performed in 2022 on the tasks’ existing mineral resources and the PEA finished in 2019. This work was performed to improve the borders of the deposit and to possibly update the classification of mineral resources from presumed to suggested where possible.
Ivana East Drilling Program
The formerly revealed RC drilling at Ivana East has actually been postponed due to technical concerns with the drilling rig and will resume when it has actually been fixed. This program becomes part of the Business’s staged method to examining targets with-in numerous 10s of kilometres from the Ivana deposit that might contribute to the tasks resource base.
Ivana Central Drilling Program
Drilling at Ivana Central was at first introduced in 2020, later on suspended due to pandemic impact, and lastly finished in 2022. The program amounted to 2,607 m of drilling in 43 scout holes ( Figure 1 ); the very first 6 holes drilled in 2020 were reverse flow (RC) holes, the following 36 holes were drilled by direct flow (DC) due to the geological conditions, and the last (AGIC-043) was drilled DC for the preliminary 31m and was finished as a diamond drill hole with core recuperated. Radiometric borehole studies were ranged from hole AGIC-007 to AGIC-043. It was not possible to survey the preliminary 6 RC holes due to the geological conditions. All holes were vertical, and due to flat strata, sample outcomes are thought to approximate real density.
Based upon borehole radiometric abnormalities and chip logging, the target REDOX front is comprehended to have actually been obstructed in 18 holes, marking a +2.4 km long and +1 km broad NNW-SSE passage at in between 40m and 60m , open up to the north and south (see Figure 2 and Figure 3 ). This REDOX front is identified by “black” sandstones with raw material and shared pyrite, accompanied by radiometric abnormalities for the most part. This “black sand” horizon was at first determined at hole AGIC-01, where it yielded 1m @ 120ppm U 3 O 8 at 46m in depth.
An overall of 281 1m samples were gathered from RC holes AGIC 001-006; Uranium varied from less than detection to 120 ppm U 3 O 8 in 1m samples. Just 56 cutting samples were recuperated from the scout drillholes AGIC -007 to AGIC 042 due to healing constraints; samples recuperated from these holes created for prospecting have possible for contamination due to the DC drilling method used. Uranium varied from less than detection to 32 ppm U 3 O 8 from 1m samples. Radiometric probe results varied approximately 1442 cps (AGC-028), an outcome constant with uranium leads to the 150 ppm U variety based upon connection with other drilling on the job (see Table 1 ).
Hole AGIC-043, the last in the program, was drilled in order to much better specify and examine the geological attributes of the REDOX front with anomalous uranium and radiometric levels that had actually been converged by previous DC drilled holes. The healing of drill core in AGIC-043 allowed in-depth logging of the geological systems and the collection of better-quality samples. The hole cut mainly great tuffaceous sediments from surface area to 38m in depth, and mainly sandy sediments from 38 to 63m in depth, ending the hole with more great tuffaceous product at 65m The black sand horizon was converged in between 46 and 62m in depth, translated as the REDOX front. Numerous samples with raised silver-cobalt-copper-uranium-tungsten were observed in the analytical outcomes and, and when it comes to the high-silver samples ( 0.35 m at 2880 ppm Ag), the core allowed re-sampling of 1/4 core for verification analyses. Emphasizes of the AGIC-043 drill results consist of:
- 1.0 m at 43 ppm Ag, 47ppm Cu and 1.3 ppm U 3 O 8 from 39m
- 0.35 m at 2880 ppm Ag, 4720 ppm Cu and 16 ppm U 3 O 8 from 46m
- 0.5 m at 89 ppm Ag, 202 ppm Cu and 13 ppm U 3 O 8 from 49m
- 0.3 m at 19 ppm Ag, 50ppm Cu and 72ppm U 3 O 8 from 60.7 m
2 extra alternate radiometric anomalous “black sand” horizons were obstructed at shallower depths in the 20- 30m depth variety in numerous holes. These black sand systems associate with chargeability abnormalities determined in the IP Pole-Dipole studies covering the location (see September 19, 2019 Press release, submitted on SEDAR). More follow-up of the forecasted level of the REDOX front at Ivana Central and evaluating of the state-of-the-art silver capacity is being performed by the Business.
Continuous Expedition Program
Regional prospecting mapping, tasting, and radiometric studies have actually been performed over the southern sector of the Amarillo Grande job. The program is gathering soil samples for detection of Pb-isotopic abnormalities that might be connected to uranium-sandstone type deposit or REDOX fronts. The expedition efforts are finished with pit tasting or auger drilling when uranium mineralization and/or radiometric abnormalities are found while mapping.
Assay Approach and QA/QC
Drill samples were sent out to ALS Argentina for preparation by drying, squashing to 70% 100pm, were processed by HF-HNO3-HClO4 food digestion with HCl leach, ICP-AES or AAS surface (OG62), on the other hand over limitations >> 1500ppm Ag were evaluated by fire assay and gravimetric surface (GRA21). Gold was processed by fire assay and AAS (AA24). Roughly every 10 th sample a blank, replicate, or basic sample is placed into the sample series for quality assurance/quality control (” QA/QC”) functions. The QA/QC internal evaluation identified that analytical outcomes reported herein are within basic market limitations.

About the Amarillo Grande Job
The Business’s 100% owned Amarillo Grande Uranium-Vanadium Job in Rio Negro Province , Argentina is a brand-new uranium district managed by Blue Sky. The Ivana deposit is the foundation of the Job and the very first part of the district for which both a Mineral Resource Quote and a Initial Financial Evaluation have actually been finished. Mineralization at the Ivana deposit has attributes of sandstone-type and surficial-type uranium-vanadium deposits. The sandstone-type mineralization is connected to a braided fluvial system and suggests the capacity for a district-size system. In the surficial-type deposits, mineralization coats loosely combined pebbles, and is open to seeping and basic updating.
The Job consists of numerous other target locations over a local pattern, at or near surface area. The location is flat-lying, semi-arid and available year-round, with close-by rail, power and port gain access to. The Business’s method consists of marking resources at numerous locations and advancing the job to prefeasibility level.
