1897: report of first work on this property. 1901: L. Benn discovered Zn and sank a pit and removed more than 100 tons of ore. 1902-1913: James Richardson bought the property and sunk 5 shafts 18 to 47 m deep along with numerous pits and trenches. 1902-1907: 3,442 tons of Zn were shipped valued at $41,550. 1914-1915: Long Lake Zn Company optioned the property, dewatered the old workings and completed 300 m of diamond drilling. 1927: M.E. Wilson of the Geological Survey of Canada dewatered and examined some of the pits and shafts. 1947-1950: Rochette Gold Mines Ltd optioned the property from J. Richardson. 1949: a 35 tpd mill was installed to process oxidized ore from the surface dumps - this was not successful. One of the shafts was dewatered and 90 m of drilling carried out. 240 tons of Zinc concentrate and 15 tons of lead concentrate were produced. 1950: 25 diamond drill holes were completed. 1966: Mid South Explorations Ltd. optioned the property and completed surface exploration. 1970-1974: Lynx Canada Explorations Ltd in partnership with Canadian Reynolds Metals Ltd purchased the mining rights and leased the surface rights. Initially 25 diamond drill holes (1830 m) were completed that outlined a number of massive sulphide lenses. Another 66 holes (5651 m) outlined the mineralization in detail. Another 68 holes (5041 m) were carried out from surface. An additional 114 holes (1370 m) of drilling was carried out underground. Ground Geophysical surveys were carried out. Production commenced on March 1, 1973 at a rate of two to three hundred tons per day. Maximum depth of the mine was 45 m. Ore was beneficiated to approximately 20% zinc in a heavy media concentrator. This concentrate was shipped to Balmat, NY. to the mill of St. Joe Minerals Corp. The mine closed on Dec 31, 1974.Total production was 94,631 short tons averaging 11.6% zinc, from which 22.3 million pounds of zinc were extracted. OFR5515. 1998: Sparton Resources diamond drill tested EM anomalies on the Long Lake zinc property. Nine diamond drill holes were completed to the west and to the east of the old mine workings. The holes were sampled and assayed for Ni, Ag, Pb, Zn (OFR 5992, p3).

Province: Grenville
Subprovince: Central Metasedimentary Belt
Geological Age: Mesoproterozoic
Jan 30, 2020 (C Papertzian) - (From GR 216, Geology of the Long Lake Area) The deposit is situated within carbonate metasediments of late precambrian age, and surrounded by mafic intrusive rocks of the Mountain Grove Mafic Intrusion also of the same age. Irregular masses and dykes of granitic pegmatite intrude the above two lithologies. The carbonate metasediments are calcite-rich and have three modes of occurrence: 1) medium to coarse grained granoblastic calcite marble. 2) fine grained to medium grained granoblastic laminated calcite marble with continuous well-defined 0.5 to 2 cm think layers. 3) very coarse grained (2 to 7.5 cm) varieties of the first unit. The band of carbonate metasediments has a strike length of 1 km and a width at the surface of 180 m. It strikes N40 to 60 degrees east with generally steep but variable dips. The geology of the mineralized zones is slightly different. On surface disseminated sphalerite, galena and pyrite occur in definite horizons within the laminated carbonate unit. Below ground the ore bodies are lens shaped and separated from one another. The ore is either massive coarse-grained sphalerite or disseminated sphalerite, galena, pyrite, pyrrhotite plus or minus chalcopyrite. The massive coarse-grained ore type is usually dark brown to black. Grain size varies from 2 to 7 cm and usually the only other sulphide minerals are minor. The disseminated ore type is medium to coarse-grained and contains sphalerite, pyrite, galena, pyrrhotite plus or minus chalcopyrite, chlorite plus or minus calc-silicate gangue. These lenses often contain pyrite-rich zones near the contact with the carbonate unit. The gangue consisted of minor quartz, pyrite and pyroxene. The contact with the carbonate of both ore types often includes calc-silicate minerals, the most common being dark green pyroxene (diopside); loss common are chondrodite and grossularite. Minor amounts of galena plus or minus molybdenite are found.

Jan 30, 2020 (Sheree Hinz) - The Long Lake deposit is in the southern portion of the Sharbot Lake domain, in the eastern part of the Composite Arc Belt. The deposit area is located within a NE-trending belt that is generally composed of mafic to intermediate meta-volcanic rocks (amphibolite gneisses). The core of the sequence is intruded by the Mountain Grove gabbroic Intrusion which is in turn intruded to the SW and the NE by the McLean Pluton granite (quartz-feldspar phyric granite to quartz-monzonite). A small belt of calcitic marble, belonging to the Grenville Supergroup, approximately 4 km long and at most 1.5 km wide is spatially associated with the SW contact of the Mountain Grove Intrusion. Many small elongated enclaves of the calcitic marble are observed in the southern portion of the Mountain Grove Intrusion. The Long Lake Zinc deposit is located within the largest of these marble enclaves which is NE-trending, 1.1 km long and less than 200m in width.

Jan 30, 2020 (Sheree Hinz) - The ore, as seen in waste piles and large blocks near the ramp opening, consists of conformable bands of massive coarse-grained sphalerite or disseminated sphalerite, pyrite, pyrrhotite with minor amounts of galena and chalcopyrite. The colour of the massive coarse-grained ore is usually a dark wine to brown to black (locally with a dark purple hue). Grain size varies greatly from 2 to 7 cm and usually, minerals other than sphalerite constitute only a minor part of the rock. Minor amounts of pyrite, pyrrhotite, galena diopside and hematite are also observed in the massive ore. The disseminated ore type is medium to coarse grained and contains sphalerite, pyrite, galena, pyrrhotite with minor chalcopyrite, chlorite and diopside. Individual zinc assays reported in drill logs are highly variable but are as high as 49.5% Zn (DDH K-9) and 50.90% Zn over 1.53m (DDH K-20) in the massive ore lenses. Even when galena was observed visually, when reported lead assays are erratic and typically less than 0.8% Pb. Silver assays, when reported are also erratic but typically below 0.5 oz/t Ag. Some notable spikes in Pb and Ag are: DDH K-12: 19.2% Zn, 9.90% Pb and 3.20 oz/t Ag over 27cm, DDH K-20: 28.52% Zn, 4.35% Pb and 2.01 oz/t Ag over 75cm.

Geologist: C Papertzian
Notes: The ore was extracted from 3 zones - A, B, and C. The A zone was the riches with grades up to 40% or more. The B zone was the most voluminous with typical grades of 23%. The C zone was smaller in volume and a little lower in grade. The B zone had a strike length of 100 m, a maximum width of 4 to 5 m and extended 30 m vertically (from GR 216, Geology of the Long Lake Area). This deposit was visited briefly on July 23, 2004 in the search for high grade sphalerite samples and coarse-grained calcite. The main opening (ramp) is fenced and is water filled. There is one other opening to the north east that was used as a water supply for the mine that is fenced. The rest of the shafts on the property are capped.
