SNOWLINE GOLD INTERSECTS 2.3 GRAMS PER TONNE GOLD OVER 282.9 METRES AT ITS VALLEY ZONE AND COMMENCES DRILLING AT GRACIE, ROGUE PROJECT, YUKON
Snowline Gold Corp. has released initial, preliminary assay results from its 2022 drilling program at the Valley zone, Rogue project, Yukon, and has provided a general exploration update. Holes V-22-005 and V-22-007 each intersected broad zones of mineralization averaging over 1.5 grams per tonne gold over significant widths. V-22-007 averaged 2.30 g/t Au over 282.9 metres from bedrock surface to 288 m depth, with assays still pending past that point for the bottom 127.1 m (31 per cent of the total hole).
"Our initial assay results demonstrate increasing scale and fertility in the Valley zone," said Scott Berdahl, chief executive officer and director of Snowline. "In an aggressive step back 154 m to test the width of the system with hole V-22-005 and an aggressive step out 340 m along the length of the system with V-22-007 we've encountered grades and intervals greater than those of our discovery holes last season. These high grades are associated with unusually high quartz vein densities that are present across a large area. The presence of consistent grades from near surface is also encouraging as it improves the potential economics of the prospect. The Valley discovery is a work in progress -- we eagerly await the remainder of results for V-22-007 and for many other holes from this year's ongoing drill campaign."
Hole V-22-007 was collared in the Valley intrusion and remained in the intrusion for its entire length. Moderate to strong (over 15 veins/metre) quartz vein intensities occur regularly throughout the hole.
Gold grades within V-22-007 exhibit a high degree of consistency. One hundred sixty-eight of 232 samples -- representing 204.85 m (non-contiguous) or 72.4 per cent of the 282.9 m length of the interval returned to date -- assayed higher than one g/t Au. Conversely, only five samples -- representing 6.5 m (again, non-contiguous) or 2.3 per cent of the length of the hole returned to date -- assayed below 0.2 g/t Au, with the lowest assay for the hole returning 0.152 g/t Au over 0.5 m. When capped at 10 g/t Au, the interval received to date (282.91 m) drops by just 0.05 g/t Au from an average of 2.30 g/t Au to 2.25 g/t Au.
Only partial results from hole V-22-007 have been received at this time. For expediency in processing, the top 282.9 m of the hole were shipped when ready on an available supply flight, independently of the bottom 127.1 m. Results for the remainder of the hole will be released when available.
Holes V-22-005 and V-22-006
Holes V-22-005 and V-22-006 were drilled along section with 2021 discovery hole V-22-003 (1.25 g/t Au over 168.7 m from bedrock surface -- see Snowline news release dated Feb. 10, 2022) to test the local width of the mineralized quartz vein system.
Hole V-22-005 was collared in the Valley intrusion as a 154 m stepback from V-21-003 to test width of the system. The hole averaged 1.03 g/t Au across its entire 331.30 m length, including 191.95 m averaging 1.52 g/t Au from 132 m downhole. As with V-22-007, capping of assays at 10 g/t Au only diminishes overall grade by 0.05 g/t Au, demonstrating the widespread and relatively consistent nature of gold mineralization.
Hole V-22-006 was collared at the same site as V-22-005 and drilled to the northeast as a further test of the width of the system. The hole encountered sheeted quartz vein mineralization in diorite, averaging 0.23 g/t over its entire 301 m length with broadly consistent grades and mineralization to the end of the hole.
Valley drilling update
Two drills are active at Valley, with 6,750 m drilled on the target so far this season for 7,554 m total drilled on the target to date. Drilling to the southeast of previous holes has extended the known strike length of the mineralization to over one kilometre, with lower vein densities to the extreme southeast. Hole V-22-024 was drilled roughly 1.3 km southeast of V-21-004 to test a magnetic low thought to be a potential southeastern extension of the Valley. Dioritic dikes up to 26.2 m drilled width (true width unknown) were encountered in drill core, but the hole was primarily hornfels and sediment, with light quartz veining.
Gracie zone drilling
Initial drilling has also commenced at the nearby Gracie zone, with sparse quartz-bismuthinite veins and three instances of trace visible gold encountered in G-22-001, the first-ever drill hole into the target.
G-22-001 intersected silicification and mostly light to locally moderate quartz veining, with three instances of visible gold. G-22-002 intersected fractured sedimentary rocks with light veining and was discontinued at 165 m. Assays for both holes are pending, and drilling at Gracie is continuing.
The hole, drilled to a total depth of 380.16 m, intersected a deformed and hornfelsed sedimentary succession. The rocks intersected in the hole predominantly exhibit biotitic and sericitic alteration with moderate silicification and minor carbonatization. Disseminated to semi-massive pyrrhotite, pyrite and chalcopyrite are associated with alteration and quartz-carbonate-sulphide veins, up to two centimetres in width, that comprise pyrrhotite, pyrite, chalcopyrite and bismuthinite with visible gold hosted in the veins at 62.9 m, 265.8 m and 275.5 m. Locally, vein densities are up to five veins/metre, though more typical is 0.5 to one vein/metre over the length of the hole. Assays for this hole are pending,
The geological setting and style of mineralization at Rogue's Valley zone indicate the presence of a bulk-tonnage gold target, with similarities to Kinross's Fort Knox mine in Alaska and Victoria Gold's Eagle mine in Yukon. Gold is associated with bismuthinite and telluride minerals hosted in sheeted quartz vein arrays along the margins of a mid-Cretaceous-aged Mayo-series intrusion. The Rogue project hosts multiple intrusions of similar age and affinity to that at Valley along with widespread gold anomalism in stream sediment, soil and rock samples. The project is thus considered by the company to have district-scale prospectivity for reduced-intrusion-related gold systems.
Valley is an early-stage exploration project without a resource estimate, and the presence or absence of an economically viable orebody cannot be determined until significant additional work is completed.
Quality assurance/quality control
On receipt from the drill site, Valley's NQ-sized drill core was systematically logged for geological attributes, photographed and sampled at Snowline's 2022 field camp. Sample lengths as small as 0.5 m were used to isolate features of interest, otherwise a default 1.5 m downhole sample length was used. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently) collected for analysis and one-half stored as a record. Standard reference materials, blanks and duplicate samples were inserted by Snowline personnel at regular intervals into the sample stream. Bagged samples were sealed with security tags to ensure integrity during transport. They were delivered by expeditor and by Snowline personnel to ALS Laboratories' preparatory facility in Whitehorse, Yukon, with analyses completed in Vancouver.
ALS is accredited to ISO 17025:2005 UKAS ref. 4028 for its laboratory analysis. Samples were crushed by ALS to over 70 per cent passing below two millimetres and split using a riffle splitter. Two-hundred-fifty-gram splits were pulverized to over 85 per cent passing below 75 microns. A four-acid digest with an inductively coupled plasma mass spectroscopy (ICP-MS) finish was used for 48-element analysis on 0.25 g sample pulps (ALS code: ME-MS61L). All samples were analyzed for gold content by fire assay with an atomic absorption spectroscopy (AAS) finish on 30 g samples (ALS code: Au-AA23). Any sample returning over 10 g/t Au was reanalyzed by fire assay with a gravimetric finish on a 30 g sample (ALS code: Au-GRA21).
Samples with visible gold and other samples returning over two g/t Au by fire assay, along with a set of randomly selected samples, will undergo further processing, analyzing the screen rejects to determine whether the screening process could introduce a sampling bias in current results by excluding coarse gold from analysis, resulting in an underreporting of true grades. Other biases are also possible.
As noted, results reported herein are considered preliminary following receipt of a low percentage of abnormal assays from standard and blank samples inserted by the company into the Valley sample stream (standard samples are prepared by a third party laboratory to have known quantities of gold, and blank samples are known to contain very limited concentrations of gold). In total, seven of 74 reference samples fell outside of acceptable limits. Two standards failed with low values underreporting gold, while four failed with high values overreporting. Reanalysis of samples run along with these reference materials will provide greater certainty in the final assay numbers. These results will be reported if a material difference is identified between the current assays and the rerun sample batches. Based on the widespread and consistent mineralization throughout all three holes reported herein, however, the company does not believe that the reanalysis of this relatively small number of samples will have a significant impact on the preliminary mineralized intervals reported herein.
During the months of July and August, 2022 (to date), 5,033,018 warrants were exercised, for gross proceeds to the company of $2,611,205.75.
About Snowline Gold Corp.
Snowline Gold is a Yukon-focused gold exploration company with a seven-project portfolio covering over 127,000 hectares. The company is exploring its flagship over-85,000-hectare Einarson and Rogue gold projects in the highly prospective yet underexplored Selwyn basin. Snowline's project portfolio sits within the prolific Tintina gold province, host to multiple million-ounce-plus gold mines and deposits including Kinross's Fort Knox mine, Newmont's Coffee deposit and Victoria Gold's Eagle mine. The company's first-mover land position and extensive database provide a unique opportunity for investors to be part of multiple discoveries and the creation of a new gold district.
These results are considered preliminary as seven out of 74 of the company's QA/QC insertions of blanks and standard reference materials into holes V-22-005 through 007 returned values of outside of acceptable limits. This is not an unusual nor necessarily unexpected failure rate. In response, five samples on either side of failed insertions will be reanalyzed along with the insertions themselves. Given the scale and general consistency of the gold mineralization across the holes where insertions did pass QA/QC screening, the company deems these preliminary results to be strongly indicative of overall grade and thus material information. Final assay results may be updated in a future release. For more information, see the QA/QC section of this release.
Information in this release has been prepared under supervision of and approved by Thomas K. Branson, MSc, PGeo, exploration manager for Snowline and a qualified person for the purposes of National Instrument 43-101.
