Gold Stock Investor News - Grizzly (TSXV: GZD) (OTCQB: GZDIF) Reports on High Grade Ag-Au-Pb-Zn Samples Obtained from the Historical Midway Mine

 

Edmonton, Alberta - October 17, 2022 (Newsfile Corp.) (Investorideas.com Newswire) Grizzly Discoveries Inc. (TSXV: GZD) (FSE: G6H) (OTCQB: GZDIF) ("Grizzly" or the "Company") is pleased to announce that it has recently received analytical results for 12 selective rock grab samples from the historical Silver(Ag)-Gold(Au)-Lead(Pb)-Zinc(Zn) Midway Mine area in the Greenwood area, about 4 km northwest of the town of Midway in the Kettle River Valley area of BC. The Midway - Picturestone mineral claims were recently acquired from Mr. Dan Hurd (see Company NR dated October 11th, 2022) and are strategically located within the Company's Greenwood land holdings and in particular the Company's Midway lands.

Highlights

  • 12 selective rock grab and composite rock grab samples from outcrop collected from the Midway Mine -Picturestone area, with 4 of 7 rock grab samples from outcropping mineralization in the Midway Mine small historical pits yielding a range of 12.05 grams per tonne (g/T) (or 0.351 ounces per ton [oz/t]) gold (Au) up to 70.8 g/T (2.065 oz/t) Au (Table 1).
  • Three (3) of the 7 selective rock grab samples from the Midway Mine pits yielded from 1,360 g/T silver (Ag) (39.7 oz/t Ag) up to 2,140 g/T Ag (62.4 oz/t Ag) Table 1.
  • All highly anomalous samples are from outcrop and characterized by the presence of abundant pyrite, arsenopyrite with visible galena and sphalerite in a siliceous chalcedonic host. The mineralization is hosted in polymetallic veins that display the presence of lead (Pb), zinc (Zn), copper (Cu), arsenic (As) and antimony (Sb) and are likely epithermal in nature.
  • Host rocks are altered with disseminated sulphide and are likely altered sedimentary rocks to altered intermediate intrusions including quartz-feldspar porphyry and diorite.
  • A selective rock grab sample from outcrop 200 m west of the main Midway Mine yielded 15.85 g/T Au (0.462 oz/t Au) and 1,530 g/T Ag (44.6 oz/t Ag), illustrating that there is potential for additional high grade mineralization in the area.

Assaying was conducted at ALS Global in Vancouver with each sample analysed for gold by a standard fire assay (Au-ICP-21), which involved the fusion of a 30 g sample aliquot and a wet chemical (ICP) finish. "Overlimit" Au-ICP21 results (>10 g/T Au) were followed up with Au-GRA21 analysis. This involved a 30 g fire assay fusion and gravimetric finish. Additionally, each sample was submitted for multi-element geochemical analysis by the ME-MS61 technique, which is an ICP-MS analysis following a near-total, four-acid, digestion of a 0.25 g sample aliquot. Initial silver and base metal (Cu, Pb and Zn) "overlimit" ICP-MS results (>100 g/T Ag and >1% for base metals) were analysed by a follow-up, "ore grade" ICP technique (OG62), which also involved ICP analysis following a four-acid digestion on a 0.4 g sample aliquot. Any samples with silver values by OG62 >1,500 g/T were re-analysed by 30 g fire assay with a gravimetric finish (Ag-GRA21). ALS Minerals has developed and implemented strategically designed processes and a global quality management system at each of its locations that meets all requirements of International Standards ISO/IEC 17025:2017 and ISO 9001:2015.

The Midway Mine and the Picturestone (aka Picture Rock) Quarry area have seen intermittent exploration and mining since the late 1800's through to as recent as 2012. In the case of the historical Midway Mine, limited underground and open pit development has occurred. The Midway Mine and the Picturestone Quarry are situated within the "Midway Window", a structural zone within the Toroda Graben exposing Late Paleozoic to Jurassic sediments, volcanics and intrusions, including the Knob Hill and Brooklyn formations, centered on an old thrust fault in a similar setting to the Golden Crown and Lexington Mine area near Greenwood, BC as displayed in Figure 1. The presence of serpentinite and listwanite in a thrust fault setting along with what is likely Jurassic aged quartz-feldspar porphyry and diorite has been noted.

The Company's Midway Lands have been a focus of exploration since acquiring lands in the area. The current status of historical and modern exploration by the Company is illustrated in Figure 1, with most of the recent work focused on lands to the west and southwest of the historical Midway Mine.

Prior owners and operators describe significant epithermal mineralization in the form vertical polymetallic sulphide veins enriched in pyrite, arsenopyrite, galena, sphalerite and stibnite, quartz veins and significant alteration at the Midway Mine and Picturestone Quarry. The Midway Mine is spatially associated with a northeast trending gold (Au), silver (Ag), lead (Pb), zinc (Zn) and arsenic (As) soil geochemical anomaly that is approximately 300 m in length and 100 m in width in the area of the Midway Mine1. Historical trench sampling yielded 2.8 grams per tonne (g/t) Au and 218 g/t Ag over a 4.5 m interval in chip/channel sampling at the Midway Mine1. Limited drilling with some significant intercepts was carried out in the 1980's to 1990 at the Midway and Picturestone prospects.

Minnova Inc. conducted a 7 hole core drilling program for a total of 1,170 m 1990 in the Midway Mine area2. No drilling has been conducted since. A total of 274 m of core was sampled and two holes tested the actual historical Midway Mine. Hole 90-1 drilled to a depth of 84.45 m intersected 23 m of altered quartz-feldspar porphyry with pyrite and some pyrite-galena veins. The best result obtained in sampling was 1.14 g/T Au (0.033 oz/t Au) and 208 g/T Ag (6.1 oz/t Ag) over 1.5 m core length. A 10.5 m interval of strongly altered quartz-feldspar porphyry returned an average grade of 0.33 g/T Au (0.001 oz/t Au) and 52.7 g/T Ag (1.54 oz/t Ag). A number of the drill holes completed intersected serpentinite, listwanite, diorite and then bottomed in Triassic Brooklyn Formation sharpstone conglomerate with pyrite and skarnified limestone clasts. A number of the other holes intersected similar geology, alteration and gold - silver values as hole 90-1. Additional trenching and drilling were recommended.

The most recent work in 2012 resulted in a recommendation of ground geophysical surveys, additional soil sampling and drilling. The work was never completed. The Company has commenced follow-up ground magnetic and electromagnetic surveys at the Midway Mine area and will conduct follow up rock sampling. Permitting in order to conduct trenching and drilling in the spring or early summer of 2023 has commenced.

The Company has recently completed Phase 1 drilling on the Dayton and Motherlode North prospects and will provide an update on the drilling in the near future.

Brian Testo, President and CEO of Grizzly Discoveries stated "We are excited at the high grade gold and silver values that have been obtained from the historical Midway Mine and potential for additional mineralization. We have had our eyes on the historical mine for a number of years! We view the acquisition of the Midway and Picturestone prospects as a good quality strategic acquisition to our current significant land holdings in the Greenwood District."
