MIDWAY
Grizzly Discoveries optioned the mineral rights to 317 hectares in seven (7) mineral claims in the Greenwood area, BC including the historical Silver (Ag)-Gold (Au)-Lead (Pb)-Zinc (Zn) Midway Mine and the Picturestone Quarry, which are about 4 km northwest of the town of Midway in the Kettle River Valley area of BC. The Midway – Picturestone mineral claims are strategically located within the Company’s Greenwood land holdings and in particular the Company’s Midway lands.
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.
An extensive rock and soil sampling program along with new geological mapping during 2023 has been conducted in preparation for drilling this fall. The work has yielded two new showings identified near the historical Midway Mine including up 5.64 g/t Au from a showing 400 m to the north of the Midway Mine and a second showing along an apparent fault structure with 4.19 g/t Au from a grab sample collected about 375 m to the west of the Midway Mine (Figure 2). At least 6 new areas with anomalous gold (> 100 ppb Au), silver or copper in soils has been identified across the Midway Mine Property with follow up work continuing to be conducted (Figure 2).
To date, gold-silver-base metal mineralization appears to be related to veins and stockworks at contacts between altered ultramafic-carbonate rocks (listwanites) in contact with diorite intrusions in a complex structural setting, with the intersections of structures playing a key role in the localization of alteration.
Highlights from 2022 Exploration Program on the Midway Mine:
- 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.
- 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).
- 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.
- A selective rock grab sample from outcrop 200 m west of the main Midway Mine yielded 15.85 g/T Au (0.462 opt Au) and 1,530 g/T Ag (44.6 opt Ag), illustrating that there is potential for additional high grade mineralization in the area.
Selected geochemical highlights for 12 rock grab samples* collected in the Midway Mine area.
*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 deposit as they are selective in nature.
