So, for instance, you can find a report on the Ontario gold camps that doesn't even mention that there is any interest at Shining Tree... doesn't name it as a camp:

As it was explained to me what will typically happen is various companies will see what they have but one will typically have the big find and the others will end of JV with the main property? Not sure that is what will happen here as we don't have enough info yet although I expect there will be more to go on before or when the ST spin happens and it begins trading on its own which should be early 2012?

Very nice explanation about the glacial till. Looks like that technique is also useful for finding kimberlites. http://en.wikipedia.org/wiki/Till

Very active mining camp there at Shining Tree.

Seems there are good gold occurrences in greenstone belts like the Abitibi where Sarissa's Shining Tree claims are.

So, it sounds like a happy coincidence that glaciers may also improve the regions chances of finding a gold discovery.

Also of note has been that part of this area is under-explored due to the land use caution and the staking rush in Tyrell township by Carl Forbes and others

"In geology, metavolcanic rock is a type of metamorphic rock. Such a rock was first produced by a volcano, either as lava or tephra. Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. Metavolcanic rock is commonly found in greenstone belts.

http://en.wikipedia.org/wiki/Greenstone_belt

"Greenstone belts have been interpreted as having formed at ancient oceanic spreading centers and island arc terranes.

Greenstone belts are primarily formed of volcanic rocks, dominated by basalt, with minor sedimentary rocks inter-leaving the volcanic formations. Through time, the degree of sediment contained within greenstone belts has risen, and the amount of ultramafic rock (either as layered intrusions or as volcanic komatiite) has decreased.

There is also a change in the structure and relationship of greenstone belts to their basements between the Archaean where there is little clear relationship, if any, between basalt-peridotite sheets of a greenstone belt and the granites they abut, and the Proterozoic where greenstone belts sit upon granite-gneiss basements and/or other greenstone belts, and the Phanerozoic where clear examples of island arc volcanism, arc sedimentation and ophiolite sequences become more dominant.

This change in nature is interpreted as a response to the maturity of the plate tectonics processes throughout the Earth's geological history. Archaean plate tectonics did not take place on mature crust and as such the presence of thrust-in allochthonous greenstone belts is expected. By the Proterozoic, magmatism was occurring around cratons and with established sedimentary sources, with little recycling of the crust, allowing preservation of more sediments. By the Phanerozoic, extensive continental cover and lower heat flow from the mantle has seen greater preservation of sediments and greater influence of continental masses.

Greenstones, aside from containing basalts, also give rise to several types of metamorphic rocks which are used synonymously with 'metabasalt' et cetera; greenschist, whiteschist and blueschist are all terms spawned from the study of greenstone belts."

Abitibi greenstone belt
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Canadian Shield

The Abitibi greenstone belt is a 2,800-2,600 million year old greenstone belt that spans across the Ontario-Quebec border in Canada. It is mostly made of volcanic rocks, but also includes ultramafic rocks, mafic intrusions, granitoid rocks, and early and middle Precambrian sediments.[1]
[edit] Geographical extent

The Abitibi greenstone belt is one of the world's largest Archean greenstone belts. It appears to represent a series of thrusted subterranes that exhibit similar geological, geochemical, and isotopical signatures as those formed during the evolution of paired active-arc-back-arc systems. The huge 2,707-2,696 million year old Blake River Megacaldera Complex is within the belt.

"The evolutionary history of the Abitibi Greenstone Belt extends from 2750 to 2660 million years, a span of 90 million years, and includes volcanism, sedimentation and plutonism. The Abitibi Greenstone Belt is found approximately 33% in Ontario and 67% in Quebec. The Belt has produced over 180 million ounces of gold, and 450 million tonnes of copper and zinc ore over the last 100 years. Greenstone belts are generally elongate formations consisting of variably metamorphosed mafic to ultramafic volcanic sequences often with associated igneous intrusions and sedimentary rocks. Greenstone belts most commonly occur within Archean, and Proterozoic cratons, as is the case with the Abitibi belt, which is found within the Canadian Shield.

The western part of the Abitibi greenstone belt contains some of the world’s largest copper-zinc and gold deposits and significant amounts of nickel-copper-platinum group element (PGE) mineralization. Early discoveries were made by classical prospecting with subsequent discoveries commonly resulting from diamond drilling targeted by electromagnetic surveys. The next generation of deposits will be found at greater depth, principally beneath the extensive overburden that covers most of the Abitibi greenstone belt. Thus, exploration will require improved knowledge of the geological characteristics of the existing deposits, the stratigraphic, plutonic, structural and metamorphic architecture of the region and will rely more heavily on expensive geophysical and geochemical techniques, verified by diamond drilling."
