Long Lake Mine (Richardson Zinc Mine; Lynx Mine), Long Lake Village, Olden Township, Frontenac Co., Ontario, Canada. The mine opened about and closed Reopened and closed during the 's. The mine is located about 9 km northwest of Parham on Long Lake . What it is: Nickel does not occur as a native element in the rocks of the Lake Superior region, but rather in certain sulfide minerals such as millerite (NiS) and pentlandite (Fe,Ni)9S8. The greatest nickel deposits in the world occur in the Sudbury, Ontario, area .
VMS deposits are major sources of the base metals Cu, Zn, Pb, as well as Au and Ag. They are classified according to metal content, gold content, and host-rock lithology and are divided into Cu–Zn, Zn–Cu, and Zn–Pb–Cu groups based on the ratio of Cu, Zn, and Pb contained in them (Franklin, ).The deposits contain the sulfide minerals chalcopyrite, . Straddling the provinces of Ontario and Quebec, Canada’s Abitibi Greenstone Belt is a kilometer-long by kilometer-wide mineral-rich geological belt that stretches from Foleyet, Ontario.
Copper mining deposit report for "Deposit #Usgs" (#USGS) in Ontario, Canada. The principal concentrations of rare earth elements are associated with uncommon varieties of igneous rocks, namely alkaline rocks and carbonatites. Potentially useful concentrations of REE-bearing minerals are also found in placer deposits, residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold.

The Long Lake zinc deposit occurs within a remnant of calcitic marble which forms a xenolith within a large gabbroic intrusion termed the Mountain Grove Mafic Intrusion.
The marble remnant has total strike length of about 1 km and is up to metres wide. Layering in the marbles strikes northeast and generally dips steeply to the northwest. The Long Lake zinc deposit was first discovered in by L. Benn and tons of ore was recovered from a small pit.
From to the property was mined using trenches and pitting - resulting in 3, tons of ore. In shafts were constructed, milling equipment was installed and another 1, tons of ore was extracted.
Ontario Department of Mines, Vol. LVI, Part VI,pp. 91 - This deposit is located on lot 3, concession V and lot 3* concession VI, Olden township, Frontenac county. It is sometimes referred to as the "Richardson Zinc Mine" or "Olden Zinc Mine".
The mine IB situated a third of a mile Wast of Long Lake post office* Map No*. It was very up-to-date at the time when the book was published, but is not the most current information. It has been greatly simplified. Discovering a deposit On August 7,two railroad workers –J.H.
McKinley and Ernest Darragh. The metamorphic activity endured for a long period, producing large feldspar, apatite and mica. One crystal “book” of biotite was reported to be 12 feet across and four feet thick.
The sedimentary deposits immediately north of Madoc which survived the turbulence of the shield’s late stage activity were typically converted to marble. The diversity of rocks found In the same location is a direct result of the rather unique origin of the Lake Ontario beach rocks in the region.
The same drumlins and other glacial features that give Wayne County its unique topography and character (WCGMC June newsletter) are also responsible for the nature of the Lake Ontario beaches. Mining Matters is a charitable organization dedicated to bringing knowledge and awareness about Canada's geology and mineral resources to students, educators and the public.
The organization provides current information about rocks, minerals, metals, mining and the diverse career opportunities available in the minerals industry. Late one afternoon, we arrived in Parham, Ontario, which is so small it's barely a town. We turned left and drove north through the countryside until we located the abandoned Long Lake Zinc Mine.
The sky finally got dark and we got our first look at the large rock. Scientific Definition MVT deposits are stratabound, carbonate-hosted sul-phide bodies, composed predominantly of zinc and lead, bound in sphalerite and galena. The deposits. Since Cross Lake Minerals has been exploring an area approximately 15 km east of Nighthawk Lake and in announced that drill hole CLS returned a 33 meter section which assayed b% zinc, *^0 lead, g/tonne of silver and Q% copper.
Since Kidd Creek Mine (a major VMS copper-zinc deposit), and Redstone. Environment Formed by reduction of sulfides in the lower part of lead, zinc and silver deposits. Sometimes also a primary mineral, either in low-temperature hydrothermal veins associated with calcite or in high-temperature veins associated with nickel or cobalt sulfides and uraninite.
Frequently associated with s: Much of the copper, zinc, lead, silver, and gold mined in Canada is mined from volcanic–hosted massive sulphide (VHMS) deposits associated with submarine volcanism (VMS deposits).
Examples are the deposits at Kidd Creek, Ontario, Flin Flon on the Manitoba-Saskatchewan border, Britannia on Howe Sound, and Myra Falls (within Strathcona Park) on.
The Kokanee Range Ag-Pb-Zn-Au vein and replacement deposits formed during Eocene crustal extension and unroofing of the Valhalla metamorphic core complex, in the hanging wall of the transcrustal Slocan Lake fault.
fossil hydrothermal system. Sulfur was derived from local country rocks, but carbon was derived from a deep-seated reservoir. Zinc Monuments in Little Lake Cemetery (GC5VMPD) was created by Skyecat on 5/16/ It's a Other size geocache, with difficulty ofterrain of 2.
It's located in Ontario, Canada. History of Zinc Zinc ores have been used in the making of brass and zinc compounds for over years, going back to the Romans who used zinc to make brass in. Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures.
They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore some occurrences, minerals can be extracted at a profit by mining. Geology is a science which focuses on the study of solid Earth, the rocks of which it is composed and the processes by which it changes.
It provides insight into the Earth's past including the evolutionary history of life and past y is commercially important for mineral exploration and for evaluating natural resources. It also helps find solutions to. It is km ( mi) long and less than m ( ft) thick.
The thickest portion of this lava flow or dome is located at the western end of Link Lake, where it is likely associated with a volcanic vent. The bulk of felsic rock in the Link Lake Formation occurs as subaqueous pyroclastic flow deposits.
DuringCanadian reserves of zinc declined by about t (3%) to a year-end total of approximately million tonnes (Mt). The greatest reduction in zinc reserves was recorded at the Kidd Creek mine in Timmins, Ontario.
As the result of lower tonnage and grades, Kidd Creek’s reserves decreased by t. Detour Lake not far from Cochrane, close by the Quebec border had a hard time finding ore for a long time.
Now they have found a good ore body and are mining gold in the shadow of the original mine. Get a prospector’s license and go out and look for gold.
After all, history shows that its location is anybody’s guess. Kuroko deposits are zoned from copper-rich near the center, to zinc-rich, to lead-rich at the outer edges of the deposit. The fluids that form Kuroko deposits have twice the salinity of average ocean water and temperatures of C.Metallurgical ContentSilverWhere to Find Silver in OntarioWhere to Find Silver in British ColumbiaWhere to Find Silver in YukonLead and ZincOre Minerals of Lead and ZincLead-Zinc Deposits near Igneous IntrusionsWhere to Find Pb & Zn In OntarioWhere to Find Pb & Zn In QuebecLead-Zinc Deposits Independent of Igneous IntrusionsWhere to Find Lead & Zinc In OntarioWhere to Find Lead & Zinc .Porphyry deposits.
Among the most distinctive hydrothermal deposits is a class known as porphyry copper deposits, so called because they are invariably associated with igneous intrusives that are porphyritic (meaning the rock is a mixture of coarse and fine mineral grains).Porphyry copper deposits (and their close relatives, porphyry molybdenum deposits) .
