View Full Version : Any help with these rocks

Dont know how to post photos so I took one and put it as my profile photo, I think I need to be looking for more of these, sand and rock bed used a glass jar and picked out maybe half of a qurt jar. worked most of the night and came up with these. Kinda looks like silver in qurts, also maybe a little gold. Spent maybe two mins looking at the river as it made the best sluice box I have ever seen. As soon as I get some rest I will post photos but please let me know if I am looking in a good spot. Thanks for all the help.

I took a look and the photo is just too low in quality to say much. Cell phones take poor quality close ups, and little thumbnail profile shots just are too tiny to see much.
Steve has instructions on posting photos to the forum, so take a look and see if you cant get some better pics uploaded.
I certainly saw nothing in the photo that looked like quartz, and mica often fools new prospectors - it can look like silver or gold to those who don't have lots of experience with finding the real thing.

Reno Chris,
Sorry for the low quality photo, but thanks for helping me out. It turn out to be fools gold not suprised for my 2nd outing to the area.

Igneous rocks that are formed as the lava cools above ground might be a clue for me to dig deeper. But I am only guessing when I say this, wouldn't this be a spot for Possible places for gold to end up since it was pushed out of the earth at a high temp? Also on the hill sides you can see deep cracks in the sides of the Mt. by earth quakes. Another sign of possible gold hang outs by the hot fluid excaping from the earth?

Just a few thoughts from a rookie, any old timers are welcome to blast me if I am thinking wrong, I have thick skinn.

Igneous means the rock material has been melted.

Igneous extrusive rocks are those which are formed as lava cools on the surface. They include rocks like Basalt. Although there are exceptions, they are generally not the best rocks in which to look for gold bearing quartz veins.

Igneous Intrusive rocks are those which melt, but never get too close to the surface while molten. They cool very slowly and form rocks with visible crystals like granite. In Alaska, many gold veins and other hard rock deposits of gold are related to igneous intrusive type rocks. See this thread: http://www.akmining.com/forums/showthread.php/2948-Golden-Goose
(a pluton is a good sized body of igneous intrusive rock)
