Would love to take core samples here

I own property in a known gold producing area (several underground placer mines in the area) and I have information about the direction the old tertiary channels flowed. I often wonder what is underneath the basalt lava cap that is the surface of my property. I figure the only way to find out is to core sample. But thats super expensive. What do you think?

Why would you spend the time and money to do that? A basalt lava cap? seriously? Youd have to have a huge operation to work through that. Reminds me of one of the basic rules of paleontology; dont go looking where you dont want to dig.

Well, since I know what I am talking about and you dont know any circumstances behind my theory involving a property you have never been to, I might just go ahead and take core samples. And yeah, a lava cap. seriously. Do some research in this part of the country.

ok first question how thick is the basalt? second you say u know the trend of the tericary channels but how far away and would they be known on both sides of you? the underground placer mines are intresting and I have read the geoloogy of the serirra nevadas. I wish you luck but worry you could miss a channel by a few feet and never know. I wounder if ground penitrating raday could trace the channels filled by the lava?

Some nearby mines are capped with about 2-300 ft of lava. Others are nearly at the surface. But see, they didnt dig a shaft straight down. They dug from the side. Old glaciers exposed the channels. And yes, my friend did the whole radar thing on his property back in 1989 and found 2 channels. (Which the old timers dug into) My friend wanted to find the confluence.

I don't own a single chair with arms on it.

I don't suck at prospecting.

You asked what people thought. Yet, got all diaper rash about one of the first responses.

I agree with the guy that gave you diaper rash.

Been a lot of newbies lecturing and disguising it as questions lately.

My Advise is, Don't ask advise if you already know the answer to your question. Spend the money and bore a hole to China. I hope your hunch pans out for you. Cheers!

check your well log.
After all it's just to satisfy your curiosity.

Maybe it will be shallow and you can start testing the gravel using a large skid steer or something.

Many have done it, Jeff Williams on youtube is doing the same thing. Here are 2 pictures of what the old timers here in AZ have done. one is an adit going into caliche until they hit the gravel, shaft runs 100-150 feet, hard to tell crawling. the picture with my thumb in the way is a shaft, about 30 feet deep until they hit the gravel, did not go in the hole. 20190609_125529.jpg 20190622_114102.jpg

I'd look for a spot where the edge of the basalt is exposed, and you can excavate under it.

Also you don't use a "core" drill to sample placer deposits.

Sometimes the best way to make $100,000 in gold is to spend $500,000 on a hunch.
