Point Location Description: Shaft
Location Method: Conversion from MDI
Access Description: The occurrence is located in Patience Township about 0.8 km north-northeast from Ozone siding on the CPR. Ozone Creek is approximately 17.6 km east of the town of Nipigon (claim map G-142). Access is via Highway 17 to a point north of the Ozone siding, then north by foot for 750 m to the shaft.
1919: J. Lawrence and A.P. Rochon discovered the Ozone Siding occurrence. Eighty tons of ore was removed. 1923: Area prospected by J. Lawrence. Shaft sunk 50 to 55 feet by an unrecorded operator (likely J. Lawrence). Sampling was also conducted. 1995: Patented claims TB 44224, 44225, 44226, 44227, 44257 and 44258 cover the occurrence.
Province: Superior
Geological Age: Archean
Dec 07, 2005 (B Nelson) - Tanton (1931) describes the occurrence on mining claims TB 3745 and TB 4737 as: A granite breccia occurs in a narrow zone on both sides of Ozone Creek between two rapids or small waterfalls flowing westerly into the creek. The showing is closer to the more northerly rapids. A small open cut occurs on the west side of the creek, as well as an old stripped and trenched area on the same side of the creek. The old workings are greatly overgrown with vegetation. Two other trenches were found about 400 m westerly from the creek showing. These trenches were dug on similar granite breccia with pink sugary quartz and barite and mineralized sparsely with galena. Here the barite, which is both massive and crystalline, gives the rock a high specific gravity. Hawley (1929) adds that the brecciated zone, which strikes E-W and dips steeply north in places, has been explored for about 30 chains (600 m). In the zone are also larger blocks of granite, which are fractured and penetrated by narrow quartz or barite stringers. The mineralized portions of the zone ranges in width from a few cm to 1.06 m. The usual width of breccia is from 30 to 60 cm. On claim No. 3745 a shaft was sunk to a reported depth of 15 m. Just to the east of this, two veins are exposed: one is from 5 to 15 cm wide; the other, 2.1 m to the north, is a stockwork of several quartz-barite veins in brecciated granite.

Dec 07, 2005 (B Nelson) - Hawley (1929) writes that a chip sample across a 1.06 m mineralized zone on claim No. 4737 gave an assay of 0.2% Pb and 3.16% Zn. Angular pieces of granite are cemented by white and amethystine quartz and some of the quartz crystals have a slight purple tinge. The breccia is quite vuggy in places and also contains some pink barite needles and galena crystals. Both brown and black varieties of sphalerite are present in the breccia. The bottom of the shaft is well mineralized with sphalerite. It averages about 5% of the volume of the vein filling. This mineralization is said to occur at a width of 2.7 m. Historical assays in old newspaper clippings indicate values as high as 45% zinc from selected grab samples and up to 3 oz/ton Ag. Samples taken by Resident Geologist personnel returned 6900 and 3.05% Pb and 2700 and 7700 ppm Zn. Gold and silver values assayed <0.01 and <0.10 oz/ton respectively.
