Grizzly Reports on Additional High Grade Ag-Au-Pb-Zn Grab Samples from 248 g/T Silver up to 2,700 g/T Silver Obtained from the Midway Mine and Copper Mountain Area Greenwood
- A total of 18 additional and new selective rock grab and composite rock grab samples from outcrop collected from the Midway Mine-Picturestone area, with 8 of 18 rock grab samples from outcropping mineralization in the Midway Mine area yielding a range of 0.119 grams per tonne (g/T) gold (Au) up to 12.85 g/T (or 0.375 ounces per ton [opt]) Au (Table 1, Figures 1 to 3).
- Three (3) of the 18 new selective rock grab samples from the Midway Mine area yielded from 248 g/T silver (Ag) (7.2 opt Ag) up to 2,700 g/T Ag (78.8 opt Ag), with highly anomalous and associated lead (Pb), zinc (Zn), copper (Cu), arsenic (As) and antimony (Sb) (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 and altered wall rock that display the presence of Pb, Zn, Cu, As and Sb, and are likely epithermal in nature. Mineralized veins with northwest and northeast orientations were noted.
- Host rocks are altered with disseminated sulphide and are likely altered sedimentary rocks to altered intermediate intrusions including quartz-feldspar porphyry and diorite.
- Anomalous Au and Ag associated with silica-potassic alteration detected along a strike length of more than 450 m in sampling along a northwest magnetic trend from the Picturestone Quarry to the Midway Mine that marks a faulted contact between diorite and serpentinite (Figures 2 & 3).
- A total of 28 of 90 new rock grab samples with greater than 0.1 g/T Au up to 96.9 g/T (2.83 opt) Au collected from the Copper Mountain area about 10 km north of Midway (Table 1, Figure 4).
- Three (3) high grade gold values (9.05 g/T up to 96.9 g/T) obtained from the historic Coronation Mine area extending the footprint of the Coronation epithermal vein mineralization (Figure 5).
- Four (4) new Au-Cu showings were identified from 100 m to 400 m west of the Mabel Jenny Au-Cu showings that were drilled in 2010 with intersections of up to 1.0 g/T Au and 4.65 g/T Ag over 30 m core length, and 4.31 g/T Au and 10.13 g/T Ag over 5 m core length.
- In addition to Au, a total of 30 of the 90 rock grab samples yielded Cu assays greater than 200 ppm up to 1,465 ppm Cu (Table 1, Figure 4). Almost all of the samples collected in the Copper Mountain area have anomalous copper. Mineralization consists of pyrite and minor chalcopyrite hosted in strongly altered diorite and/or volcanics. Skarn and/or porphyry style mineralization is the anticipated target for the Mabel Jenny portion of the Copper Mountain Prospect.

*Selective rock grab samples are illustrative of the tenor of mineralization for the material collected but may or may not be characteristic of the overall mineralization of the mineralization zone as they are selective in nature.
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 and APEX have commenced permitting for a number of other target areas, including drilling and trenching at Sappho, Midway and Copper Mountain.
The Company has recently completed Phase 1 drilling on the Dayton and Motherlode North prospects. The results have been received for Dayton and been provided in a news release by the Company dated December 23, 2022. The Company will provide an update on the results of drilling at Motherlode North in the near future. Assays are still pending for a number of drillholes.
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 this historical mine for several years and view the acquisition of the Midway and Picturestone prospects as a good quality strategic addition to our current significant land holdings in the Greenwood District. We are even more encouraged by the rock grab samples collected and reported today from the Midway and Picturestone area which yielded from 248 g/T silver (Ag) (7.2 opt) up to 2,700 g/T Ag (78.8 opt), as well as previously reported results of 1,360 g/T Ag (39.7 opt), 1,530 g/T Ag (44.6 opt) and up to 2,140 g/T Ag (62.4 opt) along with 12.05 g/T gold (Au) (or 0.351 opt) up to 70.8 g/T Au (2.065 opt)!"
