Within this syenite, gold mineralization is associated with a stockwork of quartz veinlets and narrow quartz veins, rarely greater than a few centimetres thick, that are within a broader halo of disseminated pyrite and potassic alteration. Mineralization is known to extend beyond 1,500 metres below surface and the orebody remains open at depth.
Although pure gold is rarely used as it is too soft, gold is often mixed (alloyed) with other metals. The term 'carat' is used to describe the purity of gold and is based on a total of 24 parts. Pure gold ( gold .
Throughout the district, the Archean intrusive rocks are hosted as plugs, small stocks and dikes of augite syenite, syenite and feldspar porphyry that are associated with the spread of the Timiskiming group sediments. The syenite mass that hosts most of the property's gold mineralisation extends 900m east west and 300m north-south.
Exploration by Northstar and others since then has defined additional shallow high-grade gold veins, with a historic estimate of 270,000 ounces of gold at 11.5 grams per ton, and a lower-grade bulk tonnage gold exploration target at Planet Syenite that may contain up to 500,000 ounces of near-surface gold ranging in grade from 1 to 3 grams per ton.
Apr 08, 2020· Exploration by Northstar and others since then has defined additional shallow high-grade gold veins, with a historic estimate of 270,000 ounces of gold at 11.5 grams per ton, and a lower-grade bulk tonnage gold exploration target at Planet Syenite that may contain up to 500,000 ounces of near-surface gold ranging in grade from 1 to 3 grams per ton.
Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%).Some syenites contain larger proportions of mafic components and smaller amounts of felsic material than most granites; those are classed as being of intermediate composition.
In 2011, AuRico Gold acquired Northgate Minerals and commenced open pit mining operations at Young-Davidson. First gold was poured in April 2012 and by October 31, 2013, the underground mine achieved commercial production. AuRico Gold merged with Alamos Gold .
To prospector the first Association of gold and magnetite occurs in the bottom of your cold pan in the form of black sand that contains small specks of gold. This black sand along with other heavy minerals is considered to be ore in its own right, and is often refined away from streamside to .
The United States has natural gold in every state but it takes a good concentration of AU (atomic number 79) for gold digging to be profitable. Public lands are available for new prospectors to take advantage of and dig for gold. You can dig for gold in waterways that trap the traveling gold or in dry deserts where ...
Gatling Exploration (GTR:TSX-V) is a Canadian gold exploration company focused on resource development at the Larder Lake Project, a high-grade gold deposit located in the prolific Abitibi greenstone belt. An updated NI 43-101 mineral resource update is anticipated in 2019.
Higher grade gold mineralisation occurs in 800m wide elliptical shaped porphyritic intrusions. Mining and processing at the Usak province gold mine. Drilling and blast mining methods are used to recover .

Syenite, any of a class of intrusive igneous rocks essentially composed of an alkali feldspar and a ferromagnesian mineral. A special group of alkali syenites is characterized by the presence of a feldspathoid mineral such as nepheline, leucite, cancrinite, or sodalite (see nepheline syenite).

Understanding Gold Grading . All precious metals are graded by the proportion of metal in the ore. Grams per tonne of milled ore, or g/t, is the most common metric used to represent the grade of ore.
The syenite-associated Beattie deposit (measured and indicated resources of 60.9 Mt grading 1.59 g/t Au, and inferred resources of 29.7 Mt grading 1.51 g/t Au), located in the Abitibi greenstone belt, consists of two styles of gold mineralization: lithology controlled and structure controlled.
A small high-grade (16-20 g/t) gold mining operation was centered on this discovery during the 1930's. Historic records indicate that Northshore Gold Mines produced 3.808 tons of gold ore from the Northshore Zone at an average grade of 0.64 oz/ton (21.80 g/t gold.
Panning, in mining, simple method of separating particles of greater specific gravity (especially gold) from soil or gravels by washing in a pan with water. Panning is one of the principal techniques of the individual prospector for recovering gold and diamonds in placer (alluvial) deposits. The
So didn't know exactly what to expect. GOLDN Paydirt arrived in 2 days the package represented was as advertised. Panned about a 1/3 of the bag and got gold. Smaller then pickers but way larger then flower gold. I saved the black sand and ran it maybe 4 times and kept getting flower gold.
Sep 12, 2019· Middleton Target is near Middleton Lake, in the northeast region of the claim block. It is prospective for syenite-hosted gold (Au) mineralization along syenite-basalt contacts. It connects the CLLB on its north side. Four diamond drill holes and 15 percussion holes were drilled at this location between 1964 and 1997.
Nepheline syenite is a medium to coarse-grained, light- to medium-gray, igneous rock that is composed predominantly of a silicate mineral called orthoclase (KAlSi3O8) and has a granite-like appearance. .
