@@cribbsprojects There is no ore vein in the US you are just going to walk up to, to find economical metal anything. What you do is not run around to find any vein system. You pan the washes at the base of the mountains and save yourself all that energy. If you find a drainage with anything, you work up the drainage until it stops.
Teaching is precisely my aim! I can't go to every prospect in every country, but there is an army of young enthusiastic geologists out there who are keen to go out and find their own deposit. With the right tools, they will succeed :)

On the contrary. High grade discoveries are being made on a weekly basis. Here is just one example www.linkedin.com/posts/minerdeck_weekly-gold-drilling-highlights-credits-activity-7045028120034168833-yW9D?
Hello Nick, I would like to add that each PCD system is a "World" and there is no doubt that the veinlet classification helps a lot in the evaluation of these systems; but those B veinlets are not the classic ones. A more classic veinlet is one that has quartz crystals (comb) and straighter walls, those look more sinuous. I have doubts if they are transitional between veinlets A and B or is it due to the deformation that affected the area?
The veins you describe with comb textured quartz sound similar to the original D veins of Gustafson and Hunt (which commonly represent the ore phase). The trouble is that those textures are not unique to porphyry deposits so they are not as diagnostic as the B veins. The great thing about South Korea is that there has been almost no compressional deformation since the Cretaceous so you can be sure that sinuous shapes are exactly as they formed.
Unfortunately the ASX rules around JORC reporting (and client confidentiality) prevent me from saying, but you can make an educated guess if you search the literature.
Thanks for sharing!!!
Another great content... fascinanting insights!!!
Thanks Vitor. The great thing about geology is that it has an endless supply of mysteries to be solved.
Thank you for the very nice content! If I may ask, what is your references for the classification of porphyry veins?
The lettering system was coined by Gustafson and Hunt (1975)
Thanks for sharing this great information with us.
My pleasure!
And with that, the actual intrusion system he keeps to himself.
It's all about how to find it, not showing you the result. Teach a person to fish, rather than give them fish!

GREAT INFO!!! THANKS"
Thanks. Hope it helps you to find some B veins in your part of the world.
AWESOME TIPS" Thanks for Sharing!!! Cheers" from -12c Idaho!
Thanks. It is amazingly warm for early spring in Korea this year.
Valuable information!!! I'm in charge of a magnetite mine in South Korea. I would like to invite you to show you the geology here.
Sounds interesting. Please get in touch via geologyupskill@gmail.com and I will try to organize a visit.
Excellent, thanks for share.
Are u on PDAC 2023?
Thanks Manuel. I'm in still in Korea. PDAC is a little too crowded for my liking!
Many life truths applied here!
True!
Better than most of my professors!
Thanks. Good geology is a mix of theory and field experience.
Great Channel!
Thanks Paul.

Sir kindly send me basic topic about vein types. I face many problem about it

Where is this porphyry?

They had bad geological mapping
The geological mapping wasn't too bad, but there was no mineralization or alteration mapping. That's an opportunity!
Great geologist Voice hah but really
You can always turn on the auto generated subtitles in RUclips ;)
@@GeologyUpSkill no I wasn’t saying that you have a great voice very fitting for a geologist
